Ingredients

Gather these simple ingredients to create your delectable cheesy tortellini casserole. Fresh, high-quality ingredients will always yield the best results, but feel free to adapt based on what’s available. This recipe is designed to serve 5, but you can easily adjust the quantities.

• 1 lb ground beef (For an alternative, consider using mild or spicy Italian sausage to introduce a different flavor profile and a subtle kick.)
• 1 yellow onion, diced. Finely dicing the onion ensures it cooks down smoothly and integrates well into the sauce without large chunks.
• 19 oz bag frozen cheese tortellini. The beauty of frozen tortellini is that it can go straight into the casserole without needing to be thawed or pre-cooked, saving you precious prep time.
• 24 oz jar marinara sauce. Select your favorite brand of marinara sauce; a good quality sauce forms the backbone of this dish’s flavor.
• ⅓ cup water. This small amount of water helps to slightly thin the sauce, ensuring the tortellini cooks perfectly and the casserole maintains a luscious consistency during baking.
• 1 cup mozzarella cheese, shredded. This is essential for the classic cheesy stretch and rich, melty topping.
• ⅓ cup Parmesan cheese, shredded. Parmesan adds a sharp, salty, and nutty depth of flavor that complements the other cheeses and sauce beautifully.
• 1 tsp onion powder. A concentrated way to enhance the onion flavor throughout the dish without adding additional moisture or texture.
• 1 tsp garlic powder. Offers a consistent garlic flavor that disperses evenly into the sauce.
• 1 tsp dried oregano. A foundational herb in Italian cooking, oregano adds an authentic aromatic quality to the casserole.

Ingredient Tip: For an extra layer of freshness and color, consider garnishing the finished casserole with freshly chopped basil or parsley. If you’re aiming for a vegetarian meal, simply omit the ground meat and boost the vegetable content with sautéed mushrooms, bell peppers, or spinach, adding them during the assembly stage.

Instructions

Follow these straightforward steps to assemble and bake your mouth-watering cheesy tortellini casserole. Each step is designed for clarity and ease, ensuring a delicious outcome every time. Remember to always practice kitchen safety and enjoy the process!

1. Step 1: Preheat Your Oven

   Begin by preheating your oven to 375 degrees Fahrenheit (190 degrees Celsius). This crucial first step ensures the oven is at the optimal temperature for even baking as soon as your casserole is assembled, contributing to perfectly cooked tortellini and a beautifully melted cheese topping.

2. Step 2: Brown the Meat and Sauté Onion

   In a large skillet, place it over medium heat. Add the ground beef (or Italian sausage if you’re using that alternative) and the diced yellow onion. Using a sturdy spatula or wooden spoon, break up the ground beef as it cooks. Continue to cook, stirring occasionally, until the meat is thoroughly browned and the onion has softened and become translucent, typically about 5-7 minutes. This browning process is crucial for developing deep, savory flavors. Once cooked, carefully drain any excess grease from the pan. This prevents the casserole from becoming oily and allows the flavors of the meat and onion to truly shine.

3. Step 3: Assemble the Casserole Base

   Lightly spray a 9×13 inch baking dish with a nonstick cooking spray. This essential step will help prevent the casserole from sticking to the dish, making both serving and cleanup significantly easier. Transfer the cooked ground beef and onion mixture evenly into the prepared baking dish. Next, spread the frozen cheese tortellini in a single layer over the meat mixture. Pour the entire jar of marinara sauce evenly over the tortellini and meat. Add the ⅓ cup of water, ½ cup of the shredded mozzarella cheese, all of the shredded Parmesan cheese, and all the specified seasonings: onion powder, garlic powder, and oregano. Using a large spoon or spatula, gently yet thoroughly stir all the ingredients together in the baking dish until everything is well combined and the tortellini is mostly submerged in the sauce. Ensure the seasonings are evenly distributed so that every bite offers a balanced and flavorful experience.

4. Step 4: Bake to Cheesy Perfection

   Evenly sprinkle the remaining ½ cup of mozzarella cheese over the top of the casserole mixture. This final layer of cheese will melt and bubble into that irresistible golden crust we all love. Cover the baking dish tightly with aluminum foil. Place the covered dish into your preheated oven and bake for 25 minutes. Covering the casserole during this initial phase helps to create a steaming environment, ensuring the tortellini cooks through perfectly and remains tender without drying out. After 25 minutes, carefully remove the aluminum foil. Return the uncovered dish to the oven to bake for an additional 20 minutes. This final uncovered baking period allows the cheese on top to melt, turn beautifully golden brown, and develop a delicious, slightly crispy edge, completing the casserole.

5. Step 5: Rest and Serve

   Once baked to perfection, carefully remove the cheesy tortellini casserole from the oven. Allow it to rest for about 5-10 minutes before serving. This crucial resting period allows the sauce to thicken slightly and settle, making it much easier to scoop out clean portions. Garnish with fresh basil or parsley if desired, for an added touch of freshness and color, then serve hot and enjoy!

Tips for the Perfect Cheesy Tortellini Casserole

Achieving a consistently delicious tortellini casserole is simple with a few helpful tips:

• Ensure Proper Browning: When cooking your ground meat, avoid overcrowding the skillet. If the pan is too full, the meat will steam instead of brown, resulting in less flavor. Cook in batches if necessary.
• Choose a Quality Marinara: The marinara sauce is a star ingredient here. Invest in a brand you love, or consider using your homemade marinara for an even more exquisite and personalized flavor.
• Frozen is Fine, Fresh is Flexible: This recipe is designed for the convenience of frozen tortellini. If you opt for fresh tortellini, it will cook even quicker, so you might check for doneness a few minutes earlier during the covered baking stage.
• Experiment with Cheese Blends: While mozzarella and Parmesan are classic, don’t hesitate to get creative. A blend of provolone, fontina, or even a dollop of ricotta stirred into the sauce can add more complex flavors and creaminess.
• Taste and Adjust Seasoning: Always taste your marinara and meat mixture before adding the tortellini and baking. Adjust salt, pepper, or additional Italian herbs to suit your palate. Remember, cheeses will also contribute to the overall saltiness.
• Broil for Extra Crispness: For those who adore a super crispy, golden, and slightly caramelized cheese topping, consider a quick broil for the last 1-2 minutes after removing the foil. Keep a very close eye on it to prevent burning.

Variations & Customizations for Your Tortellini Bake

This cheesy tortellini bake is incredibly versatile, making it easy to adapt to different tastes, dietary needs, or ingredients you have on hand. Don’t be afraid to experiment!

• Meat Alternatives: Beyond ground beef and Italian sausage, you can use ground turkey or chicken for a lighter meal. Leftover shredded chicken or rotisserie chicken can also be stirred in, making this an excellent way to repurpose ingredients.
• Boost Your Veggies: Enhance the nutritional value and add more flavor by incorporating extra vegetables. Sautéed spinach, diced bell peppers, sliced mushrooms, zucchini, or even a handful of frozen peas can be folded into the mixture before baking.
• Introduce Some Heat: If you enjoy a bit of spice, add a pinch of red pepper flakes to the ground meat as it cooks, or stir some into the marinara sauce for a subtle kick.
• Creamier Texture: For an even richer and creamier casserole, consider stirring about ½ cup of ricotta cheese or cream cheese into the marinara mixture. This adds a delightful smooth dimension.
• Different Pasta Shapes: While tortellini is the star, this recipe works wonderfully with other pasta shapes too! Penne, ziti, or rigatoni can be used for a similar baked pasta experience. If using dried pasta, ensure it’s pre-cooked according to package directions before combining with the other ingredients.
• Herb Enhancements: Beyond dried oregano, feel free to add other Italian herbs like dried basil, thyme, or a bay leaf to the sauce for a more complex aroma and taste.

Serving Suggestions & Storage Tips

Serving Your Delicious Casserole:

This Cheesy Tortellini Bake is a wonderfully hearty and complete meal on its own. However, it pairs exceptionally well with a simple, refreshing side salad dressed with a light vinaigrette to cut through the richness. A basket of warm garlic bread or crusty Italian bread is also a fantastic addition, perfect for soaking up every last drop of the delicious sauce. For a lighter vegetable accompaniment, steamed green beans, roasted asparagus, or broccoli florets make excellent companions.

Storing Leftovers:

One of the best things about casseroles is how well they keep! Leftovers of this tortellini bake are often even more flavorful the next day. Allow the casserole to cool completely to room temperature before transferring it to an airtight container. It can be safely stored in the refrigerator for up to 3-4 days. For longer storage, this casserole freezes exceptionally well. Divide cooled portions into individual freezer-safe containers or heavy-duty freezer bags and freeze for up to 2-3 months. Label with the date for easy tracking.

Reheating Instructions:

To reheat refrigerated leftovers, you have a couple of options: you can microwave individual portions until heated through, stirring occasionally to ensure even heating. Alternatively, for a larger portion or the entire dish, cover it with aluminum foil and bake in a preheated 350°F (175°C) oven until warm throughout, which typically takes about 20-30 minutes. If reheating from frozen, it’s best to thaw the casserole overnight in the refrigerator first, then reheat as directed for refrigerated leftovers. You may find that adding a splash of water or a little extra marinara sauce helps to restore the sauce’s consistency if it has thickened during storage.
