Holly’s Recipe Highlights
- Flavor: Mini quiches are oven-baked to fluffy perfection and bursting with savory bite-sized cheesy flavor.
- Skill Level: Make these in 4 simple steps with basic ingredients most kitchens already have on hand.
- Prep Note: Chop the veggies ahead of time and refrigerate, use pre-cooked bacon and pre-shredded cheese to save time.
- Freezing: Crustless mini quiches freeze well, maintaining their flavor for up to a month.

Ingredients That Keep It Crustless
- Eggs: Fresh eggs deliver the best flavor. You can also use liquid eggs or all egg whites as well.
- Meat: Bacon is the basic breakfast go-to, and it pairs so well with the other ingredients in this recipe, but you can use diced ham or sausage for a twist. Go vegetarian and omit the meat, but double up on the veg.
- Veggies: Colorful bell peppers and spinach are perfect keto-friendly vegetables, and they taste delicious with the other ingredients.
- Cheese: Sharp cheddar adds a lot of flavor and melts perfectly with the other ingredients, but any shredded cheese works.
Mini, Mighty & Made Your Way
- These quiches can be customized to pair perfectly with any breakfast or brunch menu. Add chopped black olives, jalapenos, diced tomatoes, and a dash of southwestern seasonings.
- Go for feta and spinach with egg whites only, for a lower cholesterol option.

- Spinach, onions, mushrooms, shredded zucchini, or any keto-friendly veggie can be added to a quiche.




How to Make Crustless Mini Quiches

Clever Quiche Tips & Tricks
- Fresh eggs are best! Place each one in a glass of water, and if it sinks and turns on its side, it’s fresh! If it sinks, but remains upright, save for hard-boiled eggs. If it floats, discard it.
- Drain the spinach well to avoid watery mini quiche, and make sure veggies are chopped into small pieces so the quiches stay whole.
- Avoid overbaking mini quiches, or they will be dense and chewy. Test them at the 20-minute mark by inserting a wooden pick in the center. If it comes out clean, they are ready.
- Let the mini quiches cool for a minute or two before removing from the pan. This allows the eggs to set properly.

From Brunch to Lunch
- Add mini quiches to a brunch bar with some breakfast sausage patties and a stack of cottage cheese pancakes.
- Keep leftover crustless mini quiches in a covered container in the refrigerator for up to 3 days.
- They are great for make-ahead or batch cooking. Double the batch and enjoy tasty pops of protein all week long, either cold or reheated in the microwave or air fryer.
- Wrap them in a low-carb tortilla for a grab-and-go breakfast or cut them into pieces and top a bed of greens for a high-protein workday lunch.

These were fantastic and just what I was looking for. The combination of flavors and the convenience of having them in muffin tins made it an excellent experience for me overall! I even added a dash of hot sauce and that gave it some kick but they are great just as they are.
