Tips from my kitchen

Here are some tips to make sure this cauliflower mac and cheese turns out perfectly every time:

  1. Don’t overcook the cauliflower! It’ll continue cooking in the cheese sauce, and you want some texture.
  2. Grate your cheese from a block for a smoother sauce that won’t turn lumpy.
  3. Want a crispy top? Make sure to broil it for a couple of minutes right at the end.

Variations

Feel free to get creative! Here are a few ways you can customize this dish:

  1. Add a handful of cooked turkey bacon or sausage for a meaty twist.
  2. Throw in some roasted vegetables like broccoli or bell peppers for extra flavor and nutrition.
  3. Spice things up by adding a pinch of cayenne or some hot sauce to the cheese sauce.
  4. Swap out cheddar for Gouda or mozzarella for a different flavor profile.

Substitutions

Here are some substitutions to fit your needs or preferences:

  1. Use almond milk or coconut milk for a dairy-free version.
  2. For a vegan option, substitute the cheese with vegan cheese and use plant-based milk.
  3. If you’re gluten-free, this recipe is already a perfect fit!
  4. Swap cauliflower for broccoli if you prefer.

Frequently Asked Questions:

Can I use frozen cauliflower instead of fresh?

Can I make this ahead for a party?

Can I use non-dairy cheese?

Yes! Just make sure to use a good melting vegan cheese for the best results.

This Cauliflower Mac and Cheese is a low-carb, veggie-packed twist on the classic comfort dish! It’s creamy, cheesy, and satisfying.

Ingredients

  • 1 large head of cauliflower, chopped into 1-inch pieces (around 8 cups)
  • 2 cups whole milk
  • 2 tablespoons cornstarch
  • Kosher salt and ground pepper, to taste
  • 1/2 teaspoon nutmeg
  • 1/2 teaspoon garlic powder
  • 1/2 teaspoon onion powder
  • 8 ounces sharp cheddar cheese

Instructions

  • Preheat the oven to 375°F.
  • Using a steamer basket fitted over a pot of boiling water, steam the 1 large head of cauliflower for around 7-8 minutes. Don't overcook it, we want it with some crunch, as it will continue to cook in the sauce.

  • In a saucepan, add the 2 tablespoons cornstarch and 1/4 cup milk (from the 2 cups whole milk). Whisk until smooth. Stir in the remaining milk and seasoning (Kosher salt and ground pepper, 1/2 teaspoon nutmeg, 1/2 teaspoon garlic powder, and 1/2 teaspoon onion powder), and place over medium heat.

  • Once the milk mixture starts to bubble, it will thicken. Add the 8 ounces sharp cheddar cheese and continue to stir until the cheese is melted and the sauce is thickened and creamy. Remove from heat.

  • Place the steamed cauliflower in an oven-safe dish. Stir in the cheese sauce and give it a quick toss to coat the cauliflower with the sauce.

  • Bake for 35 minutes. Broil for 2-3 minutes for a golden top.

Notes

  • Use shredded cheese from a chunk of cheese that you grate yourself. This is better than already-shredded, because the already-shredded has some coating that will prevent it from fully melting, and the sauce may get lumpy.
  • Feel free to use 2% milk if you like
  • Add other veggies like broccoli or zucchini
