Ingredient Notes

To make this easy baked Cauliflower Mac and Cheese, you will need the following ingredients (full measurements in recipe card below):

• cauliflower florets - this recipe works best with fresh cauliflower, so you can cut up your own heads or buy pre-cut florets and trim them to size as needed.
• unsalted butter - using unsalted butter gives you more control over flavor, but you can use salted butter if that’s what you have. Be sure to reduce or omit the salt called for in the recipe.
• all-purpose flour - to keep the recipe gluten-free, use a measure-for-measure gluten-free flour.
• milk - use regular dairy milk or try a plant-based milk like coconut milk instead.
• garlic powder - onion powder will also work in place of the garlic powder.
• cheddar cheese - you can use pre-shredded cheese to save time or buy a block and grate it yourself. You can also try Colby Jack or Monterey Jack instead.
• parmesan cheese - if you’re out of parmesan cheese, try Asiago instead.
• mozzarella cheese - mozzarella can be swapped for Monterey Jack or more cheddar as needed.
• salt
• panko breadcrumbs - you can use either regular or gluten-free breadcrumbs.
• paprika - if you don’t have paprika, try a bit of chili powder in its place.

You will also need measuring cups and spoons, a large skillet, small mixing bowl, large cooking pot, large saucepan, and 2.5 quart casserole dish (or 8-inch square baking dish).

How to Make the Best Cauliflower Mac and Cheese

First, make the breadcrumb topping.

1. Toast the breadcrumbs. In a large skillet, melt the butter over medium heat. Stir in panko breadcrumbs and cook for about 5 minutes until the breadcrumbs turn golden brown.

2. Season. Transfer into a small mixing bowl and stir in the paprika and salt. Set aside.

Next, cook the cauliflower.

Bring a large pot of salted water to a boil over medium-high heat. Add cauliflower florets and cook until tender but still slightly firm, about 5 minutes.  Drain well, rinse with cold water, and set aside.

Now, make the sauce.

1. Make the roux. In a large saucepan, melt the butter over medium heat. Whisk in the flour to make a roux. Stir constantly for about 1-2 minutes until the roux is light and golden.

2. Add milk. Gradually add in milk, whisking constantly until well incorporated and thickened.

3. Add cheese. Add garlic powder, cheddar cheese, Parmesan cheese, and mozzarella cheese and reduce the heat to low. Turn off the heat and stir until all the cheese has melted.

4. Toss in cauliflower. Add in cooked cauliflower and toss well.

Finally, assemble and bake.

1. Assemble. Transfer the cauliflower mixture into a 2.5 quart casserole dish (or an 8-inch square baking dish). Sprinkle the panko breadcrumb topping evenly on top.
2. Bake. Bake in a 375F preheated oven for 25-30 minutes until bubbly and golden brown. Let cool down for 5 minutes before serving.
