Instructions
Preheat oven to 400°F. Butter a 12-inch round cast iron skillet or a small casserole dish (like a 9×9), set aside.
Toss Brussels sprouts with oil and arrange on a baking sheet lined with parchment paper. Sprinkle 1/2 tsp salt and 1/2 tsp pepper over the sprouts. Roast in the oven for 12 minutes. Remove from the oven and set aside to cool for 5 minutes.
In a large bowl, combine the heavy cream, garlic, Italian seasoning, 3/4 cup parmesan cheese, 1 cup mozzarella cheese, and renaming 1/2 tsp salt and 1/2 tsp pepper.
Fold in the Brussels sprouts and pour mixture into the prepared skillet/casserole dish. Sprinkle the remaining cheeses (1/4 teaspoon parmesan and 1/2 cup mozzarella) over the top of the casserole.
Bake for 25 to 30 minutes, until bubbly and edges are browned. Let rest for 5 minutes and then serve immediately!
Notes
Store: Store leftover casserole in an airtight container in the refrigerator for up to 4 days.
Reheat: For best results, reheat individual portions in the microwave for 30 to 45 seconds, or warm the entire dish in a 350°F oven for 10 to 15 minutes, until heated through. Add a splash of heavy cream if it seems dry.
