Ingredients and Variations

Just like the original, cauliflower mac and cheese can be a new recipe every time!

CAULIFLOWER: One large head of cauliflower will yield about 6 to 7 cups of small pieces. Make a broccoli mac and cheese by switching out the cauliflower for broccoli or use equal amounts of both. Frozen cauliflower should be thawed and patted dry before use so it doesn’t get mushy.

SAUCE: A variety of cheeses and a generous helping of cream will give the dish its robust flavor and velvety texture. Stir in a few tablespoons of a spicy sauce like buffalo or barbecue or add some homemade Keto Taco Seasoning for a grown-up mac and cheese!

ADD-INS: Bacon bits, leftover shredded chicken, diced ham, or sliced summer sausage are all good ways to add some protein. Chopped spinach, diced zucchini, and shredded brussel sprouts add a pop of color, flavor, and a boost of nutrition.

How to Make Baked Cauliflower Mac and Cheese

  1. Season & roast cauliflower (as directed in the recipe below).
  2. Simmer cream, chicken broth, mustard and onion powder. Whisk in cream cheese.
  3. Mix cheeses together, and add half to creamy mixture. Stir and season to taste.
  4. Add cauliflower and pour into a casserole dish. Top with remaining cheese and bake.

PRO TIP: Cauliflower pieces can also be boiled or steamed. Pat dry to prevent sauce from becoming watery.

Serving Suggestions

Creamy cauliflower mac and cheese is a meal in itself, but also is delicious served with a crisp salad full of healthy fiber and nutrition! Try a tangy Cherry Tomato Salad or a Cucumber Feta Salad. Or arrange some low-carb veggies on a platter and serve with a tasty Dill Veggie Dip.

Recipe Tips!

  • Bring cream cheese to room temperature so that it is easier to blend.
  • This recipe looks best when the cauliflower pieces are broken into small, equal sizes. Just like the size of elbow macaroni.
  • If there is extra cheese sauce, freeze it for another use. Or simply add extra cauliflower, cauliflower rice, or a bag of frozen peas and carrots. (Choose veggies that are cut the same size as the cauliflower pieces).
