Preheat your oven to 375 degrees Fahrenheit.
Combine all the ingredients, except the mozzarella cheese, in a baking dish. Give it a good stir.
Cover the dish and bake for 45 minutes. Remember to stir it about 20-25 minutes in – don't forget this step!
Once it's out of the oven, sprinkle the top with mozzarella cheese.
Bake it uncovered for an extra 8-10 minutes, or until the cheese is nice and bubbly!
