Preheat oven to 400
Use a 12" or larger cast iron skillet or you will need to transfer from a regular skillet to oven safe baking dish before baking. Brown meat and sausage in skillet. Once fully cooked drain fat.
Add onion and all spices, stir.
Add marinara sauce and stir to mix with meat mixture. Simmer for 5-6 minutes.
In a small/medium bowl combine ricotta, 1/2 mozzarella and 1/2 parmesan. Stir.
Remove from heat. If your skillet is not oven safe, transfer to oven safe baking dish at this time. Evenly spread meat and sauce in pan. Use a spoon to scoop ricotta mixture onto meat and sauce. Try to cover as much as possible, flatten ricotta scoops if needed.
Cover top with remaining cheese.
Bake for 20 minutes and serve warm.
