This recipe is originally from http://stellastyle.com. I only have two minor tweaks…I don’t add any salt since the cheese seems to make it salty enough, and I hold back 3/4 cup of cheese for the topping.
Cauliflower Mac and Cheese
1 large head cauliflower, cut into small florets
3/4 cup heavy cream
2 ounces cream cheese, cut into small pieces
1 1/2 teaspoons Dijon mustard
2 cups grated Cheddar cheese
1/4 teaspoon black pepper
1/8 teaspoon garlic powder
Cook the cut cauliflower in boiling water for 5 minutes. Drain well and let sit on a dry towel on the counter while making the sauce.
Bring cream to a simmer, add cream cheese and mustard, whisking until smooth.
Stir in 1 1/4 cups of cheese, salt, pepper, and garlic powder, and whisk just until the cheese melts. Transfer cauliflower into an 8×8 pan, and pour sauce over the cauliflower. Stir so it’s all coated.
Top with the remaining cheese. Bake at 375 F until browned and bubbly hot (about 15 minutes).
