How to make creamy cauliflower mac and cheese

Prepare the cauliflower: use a sharp knife to cut the cauliflower head into small cauliflower florets and rinse them.

STEP 1: Place the cauliflower into a large pot and add enough water to cover the bottom of the pan. Cover and cook over medium-low heat until the cauliflower can be pierced with a fork, drain and rinse under cold water to stop it from cooking.

STEP 2: Wipe out the pan and make the sauce. Melt butter in a saucepan. Once melted whisk in the flour to form a paste.

Ingredient Notes and Substitutions

Cauliflower – Look for a cauliflower head that is creamy white and free of dark spots. The head should feel heavy and be tightly packed.

Cheddar Cheese – This adds a rich, sharp flavor to this recipe. If you prefer a different type of cheese, try experimenting with swiss cheese, monterey jack cheese, gouda, provolone cheese or a combination of a few types of cheese.

Butter – If the butter isn’t unavailable, you can substitute it with olive, avocado, or plant-based butter.

Flour – To thicken the cheese sauce without flour, you can us arrowroot powder, tapioca flour or cornstarch. Mix them with a small amount of water and stir them into the milk to thicken instead of making a roux.

Milk – I prefer using whole milk to make this recipe, it can be swapped with an equal amount of non-dairy milk such as coconut milk, almond milk or oat milk.

Try replacing a quarter to half cup of milk with heavy cream for a more creamy texture or add 1 tablespoon or two of cream cheese or Greek yogurt.

How to store leftovers

Leftover cauliflower mac and cheese can be stored in the refrigerator for up to three days in an airtight container.

Reheat cauliflower mac and cheese on top of the stove over medium-low heat, in the oven or in the microwave.

Spicy – Add a kick of heat with the addition of diced jalapeno peppers, red pepper flakes or a dash of hot sauce to the cheese sauce.

Buffalo – Use half blue cheese, half cheddar and a dash or two of your favorite buffalo sauce such as Frank’s.

Pasta – Add a half to three-quarters cooked whole wheat pasta or any type of pastato the sauce to make for a heartier cauli mac and cheese.
