Million Dollar Baked Tortellini Casserole is a fantastic mix of cheesy, gooey, and baked goodness all in one dish. With tender tortellini pasta wrapped around creamy cheese, swimming in a rich tomato sauce, and topped with a golden layer of melted cheese, it’s an easy way to bring everyone to the table. You can almost smell the warm herbs and garlic as it bakes.
I love making this casserole because it feels like a special meal without a ton of work. I usually whip it up when I want a comforting dinner that kids and adults alike will dig into happily. Pro tip: let it sit for a few minutes after baking—it helps everything set so your first slice stays nice and neat, plus it gives the flavors time to blend perfectly.
For serving, I like to pair it with a simple green salad or some garlic bread to soak up all the extra sauce. It’s one of those dishes that makes any evening feel a little cozy and satisfying. Plus, it reheats beautifully, so you get a tasty lunch or dinner out of it the next day, too!
Key Ingredients & Substitutions
Cheese Tortellini: Cheese-filled tortellini add creaminess and chew to this casserole. If you can’t find tortellini, ravioli or even large cheese-filled shells work well as substitutes.
Ground Beef: This gives the casserole a hearty flavor. For a lighter option, try ground turkey or chicken. You can also make it vegetarian by using cooked lentils or chopped mushrooms instead.
Marinara Sauce & Diced Tomatoes: These form the base of the sauce. Use your favorite tomato sauce or homemade marinara to add freshness. Draining the diced tomatoes prevents extra wateriness in the casserole.
Sour Cream: Adds richness and a slight tang. If you prefer, try Greek yogurt as a healthier swap—it still gives creaminess without overpowering flavor.
Mozzarella & Parmesan Cheese: Mozzarella melts beautifully for that gooey top, while Parmesan adds a salty depth. Feel free to mix in provolone or cheddar if you like a sharper taste.
How Do I Get My Baked Cheese Melty & Golden Without Overcooking?
Melting cheese perfectly on top without burning it is all about timing and temperature:
- Preheat the oven fully to 375°F to ensure even cooking.
- After assembling, bake uncovered so the cheese melts and forms a light crust.
- Check the casserole around 20 minutes to see if the cheese is bubbly and starting to brown. If not, let it go a few minutes more but watch closely.
- If cheese browns too fast, loosely cover with foil to avoid burning while the rest heats through.
- Let the casserole rest 5 minutes after baking. This cool down helps cheese set so it doesn’t slide off when serving.
Equipment You’ll Need
- 9×13-inch baking dish – I like this size because it’s just right for reaching all the baked goodness without spilling.
- Large pot – perfect for boiling the tortellini and keeping things simple with just one pot.
- Large skillet – for browning the beef mixture; a wide pan helps you cook it evenly.
- Colander – to drain the cooked tortellini easily without making a mess.
- Mixing spoon or spatula – to stir everything together smoothly.
- Measuring cups and spoons – for precise ingredients and seasoning.
Flavor Variations & Add-Ins
- Swap ground beef for cooked sausage or turkey for different flavors and textures.
- Mix in chopped spinach, kale, or mushrooms to add some veggies and boost nutrition.
- Use different cheeses like provolone or mozzarella sticks for extra cheesy pulls.
- Add red pepper flakes or Italian herbs to spice things up or give it a more herbaceous flavor.

How Much Time Will You Need?
This recipe takes about 15 minutes to prepare, 20-25 minutes to bake, plus a few minutes to let it rest before serving. Total time is roughly 40-45 minutes from start to finish.
Step-by-Step Instructions:
1. Prepare and Cook Tortellini
Start by cooking the cheese tortellini according to the package instructions until it’s tender but still firm (al dente). Drain and set aside while you prepare the rest.
2. Make the Sauce Base
In a large skillet over medium heat, brown the ground beef with the finely chopped onion and minced garlic. Cook until the beef is no longer pink and the onions become soft. Drain any excess fat to keep the casserole from being too greasy.
3. Combine Sauce and Seasonings
Stir in the marinara sauce, drained diced tomatoes, Italian seasoning, salt, and black pepper. Let it simmer gently for about 5 minutes, so all the flavors mix nicely. Then, remove the pan from heat and stir in the sour cream for a creamy touch.
4. Assemble the Casserole
Add the cooked tortellini to the sauce mixture and toss gently to coat the pasta evenly. Transfer everything into your greased 9×13-inch baking dish. Sprinkle shredded mozzarella cheese over the top, then add grated Parmesan cheese for extra flavor.
5. Bake and Serve
Bake the casserole uncovered in the preheated oven at 375°F (190°C) for 20 to 25 minutes. You want the cheese to be melted, bubbly, and slightly golden on top. Once done, let it rest for about 5 minutes so it sets nicely before serving. Garnish with chopped fresh parsley for a fresh, colorful finish.
Serve this delicious baked tortellini with garlic bread or a simple green salad for a filling and tasty meal everyone will love!
Can I Use Frozen Tortellini Instead of Refrigerated?
Yes! Just make sure to thaw frozen tortellini before cooking, or add a few extra minutes to the boiling time. Drain well to avoid excess water in the casserole.
How Can I Make This Recipe Vegetarian?
Simply skip the ground beef and use sautéed mushrooms, lentils, or your favorite plant-based meat substitute. You can keep the rest of the ingredients the same for a tasty meatless version.
Can I Prepare This Casserole Ahead of Time?
Absolutely! Assemble the casserole, cover it tightly, and refrigerate for up to 24 hours before baking. Add a few extra minutes to the baking time if baking from cold.
What’s the Best Way to Store Leftovers?
Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in the oven or microwave until warmed through, adding a splash of water or sauce if it seems dry.
