This recipe for crustless quiche is perfect for breakfast, brunch, lunch, or a light dinner.
Eggs, ham, and zucchini are baked into a cheesy, crustless ham and cheese quiche that’s as easy to make as it is delicious.
Make this Recipe For Crustless Quiche on Repeat Because…
- This keto quiche is easy to prep, ready in minutes, and is always an elegant crowd-pleaser.
- High protein and low-carb, this is the best crustless quiche recipe. It’s the perfect meal to enjoy hot or cold.
- No crust quiche is endlessly customizable so you can use leftover meat, veggies, and cheese.
Ingredients
Eggs: Be sure to use fresh eggs for the best flavor.
Add-ins: Precooked cubes of ham are delicious and convenient. A ham steak can be cut into small bite-sized pieces, or use deli ham if desired. Zucchini adds both color and valuable nutrients. Cheddar cheese gives just the right amount of flavor. Choose a mild, medium or sharp variety.
Seasoning: All you need is a little salt, pepper and dry mustard for a deliciously seasoned keto quiche.
Variations
Experiment by adding, or completely subbing in, cooked chorizo, ground sausage, and bacon bits. Other keto veggies you could include are broccoli, spinach, shredded Brussels sprouts, sliced green olives, and mushrooms. Choose your favorite cheese, or cheese blend, such as Monterey Jack, Mozzarella, Feta, Gruyere, or even a Mexican cheese blend.
Whisk in some low-carb taco seasoning and add chopped jalapenos or green chiles and black olives for a Mexican-style quiche. Chopped fresh herbs like basil, parsley, or chives would all be delicious added to the mix.
Make a higher protein quiche by using a ratio of 4 whole eggs to 6 whole egg whites.
Try mini crustless quiches. Pour the mixture into greased muffin tins and bake until they reach 165˚F.
How to Make Crustless Ham and Cheese Quiche
- Place zucchini, ham, and cheese on the bottom of a pie plate.
- Whisk remaining ingredients together and pour over the top.
- Bake (recipe below).
- Let cool before slicing.
A Successful Quiche
- Be sure to squeeze the zucchini dry in Step 2. This removes the excess moisture so the quiche doesn’t get soggy.
- If adding extra veggies, chop them finely so they don’t sink to the bottom of the quiche – you want a little of everything in each bite. Veggies that have a high moisture content, such as mushrooms, should be pre-cooked to remove the excess moisture.
- For the best results, shred the cheese from a block instead of using pre-packaged shredded cheese, which contains anti-caking agents that prohibit the best melt.
- Be sure to grease the pie pan (or oven-safe skillet) so the quiche doesn’t stick.
- Cover the top of the quiche with foil if it is browning before it is cooked in the middle.
Leftovers
Keep leftover crustless ham and quiche in an airtight container in the refrigerator for up to 3 days. Reheat covered in the microwave.
To freeze leftover quiche, cut cooled pieces into wedges, wrap them in plastic wrap, and transfer them to a zippered bag for up to 3 months. Thaw in the refrigerator overnight and enjoy cold. Reheat in the microwave or a low temperature oven if desired.

- ¼ teaspoon pepper or to taste

Notes
- Be sure to grease the pan well so the quiche doesn’t stick.
- Squeeze the liquid out of the shredded zucchini before adding.
- Avoid using pre-shredded cheese. These products often have starch added to keep them from clumping, so they may not melt as well.
- If the top begins to brown too quickly, cover with foil and continue baking.

REPIN this recipe for Crustless Quiche
I made muffins out of this recipe. They were awesome! Going to make the quiche pie for next get together with sister and mom.
So glad you enjoyed it Elaine!!
How long did you cook the muffins?
how many muffins did the recipe make?
Hi Frances, Similar to our bacon egg muffins this recipe should make 8-12 muffins.
Ty love it and so easy
Thank you Vicki! Enjoy!
There is sugar in ham, at least 1g per 2oz. But still is Keto friendly enough meaning only 4 grams of sugar for the whole pie!. Very delicious as well
So happy you love the quiche Walter!
I made this last night. It was super easy to make and was delicious. Thank you for sharing.
You’re welcome! So glad you loved it Karla!
I loved this dish. Super easy to make and delicious
It is great and easy! Glad you loved it!
Mine never stays puffy…it always flatens a bit…
This is caused by the egg to dairy ratio, your eggs may be a little larger. Try adding an extra splash of cream!
Is it still keto if I add onion and mushrooms?
Mushrooms are keto friendly. Onions are okay, but used in moderation. 1/2 cup of diced onions contains approximately 5 grams of carbs.
Can you convert to an instant pot or crock pot?
I haven’t tried it in the IP but I’m sure it would work.
Can you use spinach instead of zucchini?
Sure you can!
This was awesome, We had for dinner. I added bacon to it. My husband really enjoyed it and he’s not doing keto.
Keto is delicious! Happy to hear that your husband loved it too Natalie!
Can I use half and half instead of whipping cream? Whipping cream is not at all healthy.
As this intended to be low carb it calls for heavy cream. You can certainly make this with half and half however that will increase the carb count (and this will no longer be keto friendly).
How is half and half not keto friendly? Cream has 0.4g of carb per T and half & half has 0.5g per T. The difference is negligible.
Keto pro tip: there is no zero carb heavy whipping cream, no matter what the label says. US labelling laws allow them to round down to zero if the carb count is less than 0.5g per serving.
Thanks for the info Wendy, our half and half had higher net carbs making it not keto friendly. But if you found on with that low of carbs you could definitely use it!
Made the quiche and it is great! Husband loved it too. I covered it in frig and took a slice each morning…popped in microwave for 35 seconds. Perfect for quick morning breakfast thanks
You’re so welcome Debbie, great idea for the quick breakfast!
I’ve used spinach and red peppers it was awesome!!!
So glad you loved it Bernadette!
What kind of ham are you using? I’ve searched a lot of ham steaks, etc and they all seem to have sugar.
I am using the ham steak with the lowest sugar I can find. You’re right, many include sugar. Enjoy Christine!
Do I have to use the zucchini or can I just leave it out and add a little bit of onion.
I have only tried this recipe as written, but if you do omit the zucchini let me know how it turns out!
I don’t use zucchini and only add Onion and it’s a hit around my house.
Thank you for sharing Jenn! Enjoy!
Loved this recipe! Delicious and so easy to make! Thank you
So glad you loved it Pat!
Do u cook veg before adding into quiche? X
Can this be frozen to eat later in the week?
This quiche can be frozen for up to 2 months. Enjoy!
I’m diabetic and really have to watch my carbs. I’m looking forward to enjoying this for my dinner tonight
Let me know how you like it Betty!
Trying in the morning can already taste it!
Let me know how you like it Amy!
Thank you for posting this recipe. I recently pinned several quiche recipes and decided on making yours because the thought of eliminating the crust was appealing. This did not disappoint!! In addition to the ham and zucchini, I also added a couple cans of mildly spicy diced Hatch chilis. The results were amazing. It also tastes great warmed in the microwave as leftovers. This will definitely become a go-to recipe for breakfast and brunch.
So glad you loved it Ken! That sounds like a great addition!
I am doing keto. I don’t like zucchini, but I love yellow squash. Could I substitute the yellow for the zucchini? This recipe looks amazing. Thank you.
I think that would work perfectly.
I have made the crustless quiche several times for Church breakfast. I get rave reviews!
So happy to hear that everyone loves the quiche Susan!
I am excited to try this… it is in the oven with a few variations due to what I had in the house… I used spaghetti squash instead of zucchini and put onions peppers and mushrooms as well as a bit of cottage cheese… here’s hoping it turns out good cause it is going to a potluck in half an hour!
Hope you enjoyed it Melissa! It’s always a hit for us.
How did the spaghetti squash turn out? How much did you use?
Can this be made the night before and bake in the morning?
While I have never done that with this quiche, I think that it would work. You’ll want to take the quiche out of the fridge while your oven preheats and it may take a little longer to cook. Let us know if you try making it the day before Sue!
So simple, quick, and most of all DELICIOUS. I omit the zucchini and add scallions. Thank you for sharing your recipe.
You’re so welcome Gene! So happy to hear that you love this quiche!
I’m wanting to make this in a bundt pan. Should I double the recipe or use as is? Will the cook time change for bundt pan? Thanks.
I have only made the recipe as written so can’t say for sure. Let us know if you try it in a bundt pan Beth!
I’ve never seen shredded zucchini added to a ham and cheese casserole before. It sounds delicious! Thanks for sharing.
Thanks Roxana! Can’t wait for you to try it!
If I don’t have a pie plate, would a 9 inch cake pan work instead? Also what I be able to leave out the zucchini all together without replacing it?
We’ve only made the recipe as written. If you give it a shot, let us know how it turns out Victoria!
This recipe is fantastic! I have made it as the recipes calls for above and also several different ways with different meats and vegetables.
My one question is this recipe leaves me with a ton of leftovers. I thought about freezing portions so I could go grab a piece when I needed one. Has anyone tried freezing the leftovers?
That’s awesome Naomi! So happy to hear you are enjoying this recipe over and over. Leftovers can be frozen for up to 2 months so you can keep enjoying it whenever you want!
Made this tonight and have to say it was awesome! Couldn’t be more simple of a recipe. Now I have lunch for the week and have added a spinach salad to compliment.
That sounds like a delicious combination Shauna! Enjoy!
can I make this night before and refrigerate until morning?
We haven’t tried prepping it the night before but it should work Jo. But if you bake the night before you can definitely reheat in the morning. Let us know how it turns out!
Can you use something else apart from cream, Greek yogurt???
Hi Paula, we have only made this recipe as listed. Using greek yogurt may make your quiche a bit denser so if you give it a try let us know how it turns out!
I had gastric bypass 2 months ago and my diet is still somewhat limited. I’ve been struggling to find low carb meals that my body can tolerate. I made this recipe last night and WOW!!!! It’s the best thing I’ve eaten in months. I felt like I was cheating. I added a half cup of onions and it was so good. My husband loved it as well. It makes a large quiche but I will be eating this for breakfast lunch and dinner until it’s gone. I’ll be sure to add this one to my favorites and making it again and again and again.
So happy to hear this recipe works for you Robin! Enjoy!
Have made this recipe twice this week, BEST crustless quiche I have made! I made one with spinach, mushrooms, onion, sausage and pepper jack cheese and topped with Roma tomatoes…the second one was spinach, mushrooms, bacon, pepper jack cheese and topped with Roma tomatoes. (Used what I had on hand) Will be
Both of those sound so delicious Sandra!
I am severely lactose intolerant and mostly dairy free. I can substitute the cheese for a lactose free cheese but what could be a good dairy free substitute the heavy cream for?
Hi Amanda, I actually found a really good lactose free heavy cream at my grocery store last week. You could also try a cashew cream or something similar. It may change the consistency of the dish but it should still taste delicious.
I know this is an old post but may help someone else. A good alternative for heavy cream is to make your own. I use Fairlife whole milk and butter (butter has a VERY negligible amount of lactose with only a trace of lactose… most that cannot tolerate lactose can tolerate butter well). Use 3/4 cup milk and 1/3 cup melted butter. I prefer Fairlife to other lactose free milks because it is so low in carbs (6g per cup)
Thanks for the tip Chris!
Is that grated carrot in the photos or am I missing something?
Hey Scott, there is shredded cheese and zucchini with diced ham in the photos. But grated carrot would be a delicious addition.
So yummy and easy, I used chopped broccoli, ham, cheese and onion powder.
Those sound like delicious additions Donna! Thanks for sharing!
Just made it and its so delicious. Thanks for the recipe!
You’re welcome Nina! So glad you love it!
Started keto Monday and have had fun making new dinners every night. I found this recipe and decided to make it tonight. I didn’t have ham but had pork sausage. We loved it!!!! We sprinkled some chopped peppers on top and it was amazing. We also used Colby jack cheese. Thanks for the yummy recipe!
That sounds delicious Kelli! So glad you enjoyed the quiche. I love how versatile it is!
Made this tonight, and it was awesome!! My hubby, who hates veggies, never knew it had zucchini in it, and he loved it!! I will definitely be adding this recipe to my dinner rotation! Thank you!
So glad you both enjoyed it Connie!
I made this adding ham, cheese, green pepper, onion and spinach Really good. How many days can I eat this before I should freeze the rest ? 3,4 ?
Hi Melanie, it should last 3-4 days in the fridge before needing to be frozen.
Thank you for sharing this recipe! I followed the instructions as is, and it turned out perfect.
This looks delicious. What is a serving size please?
Hi Sonia, a serving is approximately 1 cup. It is so yummy, hope you enjoy it!
I made this with smoked salmon, leeks and asparagus! It turned out beautiful and everyone loved it.
Many thanks for the idea of a crustless quiche!
So glad everyone loved it, Tatiana! It is such a yummy dish.
Can I cook and freeze for later?
Hi Dawn, This quiche can be frozen for up to 2 months.
At the last minute, I decided to make a keto quiche for Christmas breakfast, and I chose this one. I had everything but the ham, so I fried up some bacon as a substitute. Since it is Christmas, I added some red bell pepper (for color and flavor), and we like onion, so I decided to grate it. The excess onion juice seeped out of the pile of grated onion, so I sopped up the excess with a paper towel. Otherwise, I kept everything the same, and it came out fantastic!
That sounds delicious, Jan! Thanks for sharing your version of this yummy dish!
Also I saw someone comment earlier about making in muffin cups and others said that worked well. It might be a solution to easy portion sizes for you.
We have this delicious Bacon Egg Muffins recipe that you could follow for cooking instructions, Michelle.
So good!!! I halved the ingredients, used broc instead of zuc, and baked in smaller casserole dish for 30 minutes. Will definitely make this again, yum!!
Sounds delicious, Barb! Thanks for sharing your substitutions.
I LOVE, LOVE, LOVE this recipe!! I made 12 muffins before a surgery I had and froze them. When needing food for medicine, this worked so so great. I had enough egg mixture left for at least one more but I didn’t want to use up another pan.
Today I’m trying a new variation: 1/2 lb ground beef with onion and Monterey Jack cheese. 12 muffins and 5 mini quiches. 18 for the minis, about 25 min for muffins. SOOooooo good!!!
Delicious recipe great for keto and easy to take to work and just preheat
I made this recipe with bacon, onions, garlic, parmesan and Monterey Jack cheese.
Not having a pie pan, I baked it in a 10 inch oven-safe non-stick skillet. It took 25 minutes on 375.
It turned out delicious but a little thin. I think I’ll try with a smaller diameter pan next time so it will be a bit deeper.
Happy baking!
Thanks for sharing your alterations! Glad you enjoyed it.
Can I substitute sour cream for heavy cream?
I haven’t tried it so I can’t say for sure Courtney, but if you try it I would love to hear how it turns out!
This is so good. I substituted paprika for the dry mustard because I didn’t have any. Highly recommend.
Amazing and versatile recipe. I have used various veggies such as mushrooms, asparagus, or broccoli instead of zucchini. I cook them crisp tender and pat dry before adding. Have used sausage, tuna and chicken instead of ham. Use this basic recipe and add whatever u have available.
Very bland!!!
I added onion powder abd a bit of garlic powder. Still not enough! I would double the mustard, more onion a d garlic powder. Also more cheese, something more flavorful. I doubled the ham a d would do it again.
Oh my word. This recipe was such a hit! I actually doubled the recipe, and for convenience served it in an 8.5 x 11 inch pan. It was perfect. I did generous amounts of zucchini, ham and cheese, i.e. slightly more than double, and the family was enamored. We will be having this again – thanks for a great recipe!
What about substituting Gruyere cheese for cheddar cheese?
That would be delicious Angella!
Delicious. I used white Vermont sharp cheddar and Tillamook swiss. I also added 1/2 tsp of herbes de Provence .
Just made this quiche. It smells lovely.thankyou for sharing the recipe.
The flavor of this quiche was really good; however, I found the texture to be spongy. Anyone know why that might be? I did not vary the recipe at all.
Oh no Sherrille! It could possible be overcooked. Did you make sure to cook until just set?
I love Quiche, and this recipe looks like good ol’ basic Quiche. I will be adding some spices to add to the flavors. Some onion, garlic and perhaps a bit of the popular Slap Your Momma seasoning. I think I will add some baby shrimp. Crab too sounds like a good idea. Instead of Zucchini, broccoli or peas. I will make it this week. Thanks for sharing. **
We would love to hear how it turns out for you, Judy!
I made this recipe with leftover pate and added sauteed swiss chard, shallot and garlic. It was magnificent.
Delicious! I omitted the zucchini and added about 3/4 cup chopped, cooked, bacon. (I think I’ll add some slivers of spinach sometime). This is a definite keeper!
Yum! That sounds delicious, Patricia.
