This quick cauliflower mac and cheese recipe is creamy, cheesy, and made with simple ingredients. It’s a healthy option that can be served as a side dish or as an easy meatless meal, oven-baked with roasted cauliflower for added flavor.
Preheat the oven to 425°F. Line a baking sheet with parchment paper.
Chop the cauliflower into bite-sized pieces, then place the pieces on the baking sheet and drizzle the olive oil all over. Toss gently to distribute the oil.
Roast for about 30 minutes, flipping all of the pieces halfway through.
While the cauliflower is roasting, start the cheese sauce by melting the butter in a large pot over medium heat. Once the butter is melted, sprinkle in the flour and spices and stir until the mixture is bubbly. This is called a roux.
Add the milk into the pot very slowly while continuing to stir. Remove the pot from the heat when the roux is thickened and bubbly.
Stir in the cheese until the sauce is smooth and all one even color.
Once the cauliflower is fork-tender, remove it from the oven and fold it into the cheese sauce.
