Italian Sausage Casserole Recipe
This casserole is so simple to make that you’ll want to add it to your regular meal rotation. It will only take you 5 minutes to throw together! The hardest part is waiting for it to finish cooking. Here’s how it all comes together:
- Add: Preheat the oven to 425 degrees Fahrenheit and then spray a 9x13x2-inch baking dish with cooking spray. Slice the sausage into ¼-inch thick rounds, then place the sausage disks on top of the uncooked pasta at the bottom of the baking dish.
- Combine: Pour the broth, marinara sauce, Italian seasoning over the sausage and pasta. Add salt and pepper to taste, then stir to combine.
- Bake: Cover the baking dish with aluminum foil, then bake for 40 minutes. Remove the foil and stir the casserole. If the noodles aren’t cooked through yet, add more broth or water. Stir, cover, and then cook for 5 more minutes.
- Add Cheese: When the noodles are cooked and tender, top the casserole with the parmesan and mozzarella cheese. Bake uncovered for an additional 5 minutes, until the cheese is melted and bubbly. Remove from the oven and let the casserole rest for at least 5 minutes before serving.

The great thing about this one pan recipe is how easy it is to adjust it by using what you have on hand. Here are some easy ways to make this Italian sausage casserole your own!
- Different Pasta: You can use whatever pasta you have on hand. The cooking time may vary depending on the type of pasta you use.
