Tips To Make Keto Cauliflower Mac and Cheese

Don’t overcook the cauliflower. It will continue to cook as it bakes.
Drain the cauliflower very well so your mac and cheese isn’t watery.
Experiment with different cheeses. Cheddar, fontina, mozzarella and gouda are all great alternatives.
Always use freshly grated cheese. It will melt better and smoother and taste creamier.
Don’t overheat the cheese sauce or it may break and become oily.
To make the topping extra crunchy, broil for a few minutes before serving.
No cauliflower? Steamed broccoli can also be used, but the flavor will be a little more pronounced.
Customize this recipe by adding garlic, chopped veggies, shredded chicken or bacon.
Make it spicy by adding sliced jalapeno or green chilis.
