Preheat your oven to 400 F. Place parchment paper in a cast iron skillet or baking dish.

In a mixing bowl, take your frozen cauliflower gnocchi and toss it in the olive oil, salt, pepper, Italian seasoning, and red pepper flakes. Par-cook your gnocchi for 10 minutes in the oven or in an air fryer (if using the air fryer, pre-heat to 350 F). The gnocchi should be tender and defrosted.

While the cauliflower gnocchi is partially cooking, prep your toppings (cook any sausage, slice your veggies, etc.)

Remove and toss the gnocchi into a bowl with the tomato sauce and place into your parchment covered skillet. Paper is necessary if using cast iron to prevent a chemical reaction with the iron and the tomato sauce. If you don't have paper use a baking dish, pie plate, or similar size pan.

Layer the skillet with your gnocchi, half the cheese, your toppings, and then the remaining cheese. Bake for 20 minutes until heated through and bubbling.

If you'd like, you can broil the top for about 3-5 minutes (watch it or it could burn).

Remove from the oven and let it cool slightly before serving. Garnish with parmesan cheese, and seasonings and fresh basil if desired.
