Ingredients
Gathering your ingredients is the first step to creating this delightful tortellini casserole. While the list is straightforward, a few notes on selection can elevate your dish.
- 1 19 oz bag frozen tortellini (Choose your favorite filling – cheese, meat, or spinach & ricotta work wonderfully. No need to thaw or pre-cook!)
- 24 oz jar spaghetti sauce (Pick a good quality marinara or your preferred red sauce for the best flavor.)
- 15 oz jar alfredo sauce (The combination of red and white sauce creates a delightful “pink sauce” that is rich and creamy.)
- 2 cups shredded mozzarella cheese (Freshly shredded cheese melts better than pre-shredded, but either works.)
- 1 lb Italian sausage links (Remove casings and crumble. Use mild or hot depending on your preference. Ground Italian sausage is also an option.)
- 1 white onion diced (Any type of onion will do, but white onion offers a mild sweetness.)
Instructions
Follow these simple steps to assemble your incredible tortellini casserole. Each instruction is designed to be clear and easy, ensuring a perfect bake every time.
- Step 1: Prepare Your Oven and Dish. Preheat your oven to 400℉ (200℃) and generously grease a 9×13 inch baking dish. Greasing prevents sticking and makes cleanup much easier.
- Step 2: Cook the Sausage and Onion. In a large skillet over medium-high heat, cook the Italian sausage links (removed from casings and crumbled) with the diced white onion. Break up the sausage with a spoon as it cooks until it is no longer pink and the onion is softened and translucent.
- Step 3: Drain and Combine Sauces. Once the sausage is thoroughly cooked, carefully drain any excess grease from the pan. This step is crucial to prevent your casserole from becoming oily. Then, add both the spaghetti sauce and the alfredo sauce to the pan with the sausage and onion. Stir everything together until well combined, creating a wonderfully creamy pink sauce. Now, gently fold in the frozen tortellini, ensuring each piece is coated in the delicious sauce mixture.
- Step 4: Layer the Casserole. Spread half of the tortellini mixture evenly into the prepared baking dish. Sprinkle about 1/2 cup of shredded mozzarella cheese over this first layer. Then, add the remaining tortellini mixture from the pan on top. Finally, generously sprinkle the remaining 1.5 cups of mozzarella cheese over the entire casserole for a beautifully cheesy crust.
- Step 5: Bake to Perfection. Cover the baking dish tightly with aluminum foil. Bake in the preheated oven for approximately 40 minutes. This covered baking allows the tortellini to cook through and absorb the flavors while keeping the casserole moist. After 40 minutes, remove the foil and bake for an additional 10 minutes, or until the cheese on top is bubbly, golden brown, and slightly crispy.
Once out of the oven, let the casserole rest for 5-10 minutes before serving. This allows the sauces to set and makes for easier, cleaner serving. Enjoy your homemade, comforting tortellini casserole!
Tips for the Perfect Tortellini Casserole
- Don’t Pre-Cook Tortellini: Using frozen tortellini directly from the bag is key! It cooks perfectly in the oven, absorbing the rich sauces and becoming tender without getting mushy.
- Drain the Grease: Italian sausage can release a lot of fat. Ensure you drain it thoroughly after cooking to prevent your casserole from being greasy.
- Seasoning is Key: While jarred sauces are convenient, taste the mixture before adding tortellini. You might want to add a pinch of salt, black pepper, garlic powder, or Italian seasoning to enhance the flavors.
- Rest Before Serving: Letting the casserole sit for a few minutes after baking allows the sauces to thicken and settle, making for cleaner slices and preventing it from falling apart.
Delicious Variations & Substitutions
This tortellini casserole recipe is incredibly versatile. Feel free to experiment with these ideas to suit your taste or what you have on hand:
- Protein Swaps:
- Ground Beef or Turkey: Replace Italian sausage with 1 lb of seasoned ground beef or turkey for a different flavor profile.
- Shredded Chicken: Stir in pre-cooked shredded rotisserie chicken for an even quicker assembly.
- Vegetarian: Omit the sausage entirely and add sautéed mushrooms, bell peppers, zucchini, or a can of drained lentils for a hearty vegetarian option.
- Add More Veggies: Sauté spinach, chopped bell peppers, sliced mushrooms, or zucchini with the onion and sausage for added nutrients and flavor.
- Cheese, Please!: Beyond mozzarella, consider adding a layer of provolone, a sprinkle of Parmesan, or a blend of Italian cheeses for extra complexity. A dollop of ricotta cheese stirred into the sauce can also add incredible creaminess.
- Spice It Up: If you love a bit of heat, add a pinch of red pepper flakes to the sausage and onion mixture.
- Herbs and Aromatics: Fresh basil, oregano, or parsley chopped and stirred into the sauce will brighten the flavors. You can also add minced garlic to the pan with the onion.
- Creamier Sauce: For an even richer sauce, stir in a splash of heavy cream or a tablespoon of cream cheese along with the jarred sauces.
Serving Suggestions for Tortellini Casserole
This cheesy tortellini casserole is a complete meal on its own, but it pairs beautifully with a few simple sides:
- Fresh Green Salad: A light, crisp green salad with a vinaigrette dressing cuts through the richness of the casserole perfectly.
- Garlic Bread or Breadsticks: Essential for soaking up any leftover sauce and adding a satisfying crunch.
- Roasted Vegetables: Roasted asparagus, broccoli, or green beans make excellent companions.
Storage and Reheating
- Storing Leftovers: Any leftover tortellini casserole can be stored in an airtight container in the refrigerator for up to 3-4 days.
- Freezing: This casserole freezes wonderfully!
- To Freeze Cooked Casserole: Let it cool completely, then cover tightly with plastic wrap and then foil. Freeze for up to 2-3 months. Thaw in the refrigerator overnight before reheating.
- To Freeze Unbaked Casserole: Assemble the casserole as directed, but do not bake. Cover tightly and freeze for up to 1-2 months. When ready to bake, thaw in the refrigerator overnight, then bake as directed, adding an extra 10-15 minutes to the covered baking time.
- Reheating:
- Oven: For best results, reheat individual portions or the entire casserole in a preheated oven at 350°F (175°C) until heated through, about 20-30 minutes for a full casserole, covered with foil to prevent drying out.
- Microwave: Individual servings can be reheated in the microwave for 2-3 minutes, stirring halfway through, until hot.
