Prep. Preheat oven to 450 F and line a baking sheet with parchment paper.
Roast cauliflower. Toss cauliflower in olive oil, Italian seasoning, salt, and ground black pepper, and spread onto a baking sheet. Bake in the preheated oven for 25 minutes, or until the florets begin to brown.
Make the sauce. Melt the butter in an oven safe pan over medium heat. Once melted, add the heavy cream and stir to combine. Sprinkle in the cheddar a little at a time as it melts. Cook on low until everything has melted together.
Assemble + bake. Remove from heat and stir in the cauliflower. Sprinkle the top of the dish with parmesan. Bake in the oven for 10 minutes, or until the top begins to brown.
Notes
Optional topping: 1/2 cup crushed pork rinds or bread crumbs for a bit of texture.
We also love adding 4 ounces of pancetta to the cream sauce.
