How to Make Homemade Macaroni and Cheese

If you’re wondering how make homemade macaroni and cheese, look no further! This delicious keto mac and cheese recipe gives you the option to use real macaroni as well. While the name keto cauliflower mac and cheese is somewhat of a misnomer, it’s still absolutely delicious and a more healthy version than the original.

Eating real macaroni and cheese and staying in ketosis is difficult. Most pasta is very high carb and low carb varieties often don’t taste very good. That’s where cauliflower comes in as a tasty substitute for macaroni. Although it doesn’t taste exactly the same, this keto cauliflower mac and cheese recipe definitely hits the mark on cheesy goodness! Or, if you don’t mind the carbs, read on because you’ll have the option to use real macaroni too.

How to Make Homemade Macaroni and Cheese Healthier

Mac and cheese is a classic comfort food. The original Kraft Mac and Cheese has 58 grams of carbs in a one cup serving. And it’s not even that good! That’s exactly why you should learn how to make homemade mac and cheese (or the more common web search for how make homemade mac and cheese.) Making homemade mac and cheese from scratch isn’t that hard. Plus, it tastes so much better than what you get out of the box. Even better, this baked version adds more cheese to the top for extra cheesy mac and cheese.

Keto Cauliflower Mac and Cheese

To make the keto cauliflower mac and cheese, everything is same as traditional homemade mac and cheese. The only difference is you’re using cauliflower instead of macaroni…duh.

If you can find a keto or low carb pasta that does taste good too you, it’s perfectly acceptable to use it in this recipe. I’ve tried several brands and I prefer sticking with cauliflower.

How to Make (How Make Homemade Macaroni and Cheese): Traditional Version

If you want to make the real macaroni and cheese version, you’ll substitute eight ounces of macaroni for the cauliflower. Boil the macaroni for about seven minutes. It should still be fairly firm because it will finish cooking in the oven.

So that’s really the only difference between the two! The macros below are for the healthier keto cauliflower mac and cheese variation. If you make this with real macaroni, the net carb count per serving goes from 3 grams to 23.
