Ingredients for the Perfect Mac and Cheese

ingredients for cauliflower mac and cheese
  • Cheese – For a super smooth cheese sauce, start with some high-quality, sharp cheddar and then add another of your favorite cheese. I chose Gruyere cheese, but you can use White Cheddar, Monterey Jack, etc.
  • Cauliflower – You’ll need about one medium head of cauliflower chopped into small, bite-sized florets. 
  • Heavy Cream adds that extra creaminess and helps blend all the ingredients.
  • Seasonings such as garlic powder, paprika, pepper add a distinct but not overpowering note to the sauce. Feel free to play around and add your favorite seasonings.

How to Make Cauliflower Mac and Cheese

The secret is the sauce, which is so smooth and creamy because it’s a combination of butter, three types of cheese, heavy cream, and spices. It will naturally thicken into this really creamy low carb cheese sauce that’s perfect for pasta. 

Here’s everything you need to do to make the most fantastic sauce for this creamy cauliflower:

  1. Boil the cauliflower until for tender but still a little crunchy or to your desired texture. Drain well and set aside.
  2. Melt the butter in a medium saucepan over medium heat. Add in the heavy cream, and stir to combine.
  3. Once hot, add the softened cream cheese, spices and continue stirring until fully incorporated.
  4. Reduce the heat and add in shredded cheese.
  5. Pour over the “cauliflower” pasta.
  6. Serve hot, topped with green onions of crispy bacon. Yum!

Tips for a Creamy Cheese Sauce

  1. Grate your cheese at home. To make sure your cheese is going to melt properly and have the best flavor possible, take this extra step. I promise it’s a game-changer.
  2. DO NOT ADD CHEESE TO THE EXTREMELY HOT SAUCE. When adding the grated cheese, it’s VITAL to reduce the heat and wait until the sauce stops boiling. If you add cheese to the boiling sauce, you will end up with a gritty texture.
  3. Use your favorite cheese – I chose cheddar and Gruyere, but you can change things up and make different combinations.
