You’ll love how easy it is! Just mix everything together, pop it in the oven, and let the magic happen. Perfect for busy days when you want something cozy and comforting.
Key Ingredients & Substitutions
Tortellini: Cheese tortellini is the star here! If you can’t find it, any pasta shape like shells or penne can work, but make sure to cook it a bit less since the sauce will bake it further.
Italian Sausage: Ground Italian sausage gives great flavor. If you want a lighter option or need to avoid red meat, turkey or chicken sausage are good swaps. You can also use lentils for a vegetarian version.
Marinara Sauce: A jar of marinara makes it simple. If you’re feeling adventurous, homemade sauce can be made with tomatoes, garlic, and herbs. Canned tomato sauce can work too, but add some herbs for flavor.
Cheeses: Mozzarella is important for that gooey texture. Use part-skim for a healthier option. Ricotta can be swapped for cottage cheese if you’re looking for a lower-fat alternative, but it will change the creaminess a bit.
How Do You Get the Cheese Melty and Golden?
To achieve that perfect bubbly cheese topping, you want to ensure the following:
- Mix mozzarella into the casserole before baking; this adds creaminess.
- Sprinkle extra mozzarella on top just before it goes in the oven for that beautiful melted layer.
- Keep an eye on the casserole for the last few minutes to prevent burning; you want it golden, not dark.
Let it cool a few minutes before serving so cheese has time to set for cleaner portions. Enjoy your cheesy delight!

- 1 cup ricotta cheese

- 1/4 cup chopped fresh parsley (or 1 tsp dried Italian seasoning)
- 1/2 cup chopped tomatoes (fresh or canned)
- 3 cloves garlic, minced
- 1/2 cup onion, finely chopped
- 2 tbsp olive oil
- Salt and pepper, to taste
- Red pepper flakes (optional, to taste)
How Much Time Will You Need?
This delicious casserole will take about 15 minutes to prep and around 30 minutes to bake. So, you can expect to have it ready in about 45 minutes—perfect for a busy weeknight dinner or a cozy weekend meal!
Step-by-Step Instructions:
1. Preheat Your Oven:
Start by preheating your oven to 350°F (175°C). While it’s warming up, lightly grease a 9×13-inch casserole dish so your casserole won’t stick!
2. Cook the Tortellini:
Next, cook the tortellini according to the package directions until they are al dente. Once they are just right, drain them and set aside.
3. Sauté the Vegetables:
In a large skillet, heat olive oil over medium heat. Add the finely chopped onion and minced garlic to the pan. Sauté them until the onion is translucent and fragrant, which should take about 3-4 minutes.
4. Brown the Sausage:
Now, add the ground Italian sausage into the skillet. Cook it while breaking it up with a spoon until it’s browned and cooked through, which will take around 6-8 minutes. Drain any extra fat in the pan to keep it nice and healthy!
5. Mix in the Flavors:
To the sausage mixture, stir in the marinara sauce, chopped tomatoes, parsley (or Italian seasoning), and sprinkle in salt and pepper. If you like a little kick, toss in some red pepper flakes! Let it all simmer together for about 5 minutes to let those flavors blend nicely.
6. Combine Everything:
In a large mixing bowl, combine the cooked tortellini, the sausage sauce mixture, ricotta cheese, 1 cup of mozzarella cheese, and grated Parmesan cheese. Gently fold everything together so the tortellini is well coated.
7. Assemble the Casserole:
Transfer the delicious mixture into your prepared casserole dish and spread it evenly. Make it look nice and even!
8. Add More Cheese:
Now for the best part—sprinkle additional shredded mozzarella cheese over the top. Cheese is life, right?
9. Bake It Up:
Pop your casserole in the preheated oven and bake it for 25-30 minutes, or until it’s bubbly and the cheese on top is melted and lightly golden brown.
10. Cool and Serve:
Once it’s done, let the casserole cool for about 5 minutes before serving. If you’d like, garnish with a sprinkle of fresh parsley for a little color and freshness!
Enjoy your creamy, cheesy Million Dollar Tortellini Casserole!
Can I Use Frozen Tortellini?
Absolutely! If you’re using frozen tortellini, there’s no need to thaw it. Just cook it according to the package instructions while your sausage and sauce are simmering.
How Do I Store Leftovers?
Store any leftovers in an airtight container in the fridge for up to 3-4 days. Reheat in the microwave or oven, adding a splash of marinara sauce if it seems dry.
Can I Make This Casserole Ahead of Time?
Yes! You can assemble the casserole and then cover it with foil. Store it in the fridge for up to 24 hours before baking. Just add a few extra minutes to the baking time if you’re cooking it straight from the fridge!
What Can I Substitute for Ricotta Cheese?
If you’re looking for a substitute, cottage cheese is a great option! You can also blend silken tofu or use cream cheese for a different texture and flavor.
