Ingredients You’ll Need

The ingredients here come together in perfect harmony to create the ultimate cozy casserole. Plus, many of these are pantry staples or fresh finds that make this a go-to weeknight winner. Here’s what you’ll want:

• Olive Oil: I prefer extra virgin for that slight fruity flavor when sautéing the onions and garlic.
• Lean Ground Beef: I use 97/3 to keep it lean but flavorful without too much grease.
• Small Onion: Diced finely so it melts into the sauce without overpowering.
• Garlic Cloves: Minced fresh is a must—garlic powder just won’t do.
• Crushed Tomatoes: Canned works great, and I sometimes crush whole peeled tomatoes by hand for texture.
• Tomato Sauce: Adds richness and balances the texture.
• Dried Italian Seasoning: A blend is so handy here—gives that signature savory flavor without fuss.
• Kosher Salt: Essential for seasoning; remember, it’s our flavor booster.
• Freshly Ground Black Pepper: Adds a gentle kick—freshly ground tastes best.
• Fresh Cheese Tortellini: You want fresh for the right tender-chewy texture that bakes beautifully.
• Mozzarella Cheese: Freshly grated melts perfectly—avoid pre-shredded if you can.

Variations

I often like to switch things up with this Cheesy Baked Tortellini Casserole Recipe depending on what’s in my fridge or who’s coming over. The base is so forgiving and adaptable, so feel free to get creative!

• Vegetarian Version: I swap ground beef for sautéed mushrooms, zucchini, or spinach—and add extra mozzarella for richness.
• Spicy Kick: Sometimes I sprinkle red pepper flakes into the sauce for a little heat; my family loves this twist.
• Cheese Blend: Mixing mozzarella with parmesan or provolone adds complexity to the cheesy top layer.
• Using Frozen Tortellini: You can use frozen, but I slightly reduce bake time and add a bit more sauce for moisture.

How to Make Cheesy Baked Tortellini Casserole Recipe

Step 1: Sauté the Aromatics and Brown the Beef

Start by heating the olive oil in a large skillet over medium heat. Toss in diced onions and cook until they’re soft and translucent—this usually takes about 5 minutes. Then add the minced garlic and sauté for just about a minute more until fragrant, but don’t let it burn! Next, add your lean ground beef, breaking it up with a spoon as it browns evenly. You’ll want to cook it through until there are no pink bits left—about 6 to 8 minutes. The smell at this stage is seriously amazing and sets the tone for the entire dish!

Step 2: Build the Sauce

Once the beef is perfectly browned, stir in the crushed tomatoes and tomato sauce. Sprinkle the dried Italian seasoning, kosher salt, and freshly cracked black pepper over the sauce. Give everything a good stir to combine. The sauce doesn’t need to simmer for long since it’s going to bake later—but letting it bubble gently for 5 minutes helps the flavors marry nicely. I discovered that hand-crushing whole peeled tomatoes adds a lovely texture if that’s what you have on hand.

Step 3: Add the Tortellini and Cheese

Now, stir in the uncooked fresh cheese tortellini directly into the sauce. This is the magic part—you don’t need to boil the pasta first! The tortellini will cook perfectly in the casserole. Mix in about half of the mozzarella cheese (around 1 1/2 cups) to start layering that cheesy goodness throughout the casserole. This step ensures every bite is a perfect blend of sauce, pasta, and cheese.

Step 4: Assemble and Bake

Transfer your cheesy tortellini mixture into a 9×13-inch casserole dish and spread it evenly. Sprinkle the remaining 1 1/2 cups of mozzarella cheese over the top for that irresistible golden crust. Cover the dish tightly with aluminum foil—this locks in moisture so the tortellini cooks up tender and the cheese melts beautifully without burning. Pop it in your preheated oven at 350°F (175°C) and bake for about 40 minutes, until it’s hot and bubbly. When it’s ready, you’ll see the cheese beautifully melted and slightly browned around the edges. Let it sit for a few minutes before digging in!

How to Serve Cheesy Baked Tortellini Casserole Recipe

Garnishes

I like to finish my cheesy baked tortellini casserole with a sprinkle of freshly chopped basil or parsley—it adds a pop of color and brightens up the richness. Sometimes, a dusting of grated parmesan right before serving brings an extra savory note. If you like a bit of heat, a pinch of crushed red pepper flakes over the top is fantastic.

Side Dishes

To balance the richness, I often serve this casserole alongside a bright green salad with a tangy vinaigrette or some garlic-roasted broccoli. A crusty baguette or garlic bread is always a hit too—perfect for mopping up every last bit of that sauce.

Creative Ways to Present

For special occasions, I’ve baked this casserole in individual ramekins or mini cast iron skillets—everyone loves having their own cheesy pot of goodness. You can also add a breadcrumb topping mixed with melted butter and parmesan for an extra crunchy contrast. It’s a simple step that impresses every time!

Make Ahead and Storage

Storing Leftovers

My family almost never has leftovers, but when we do, I store them in airtight containers in the fridge for up to 4 days. Reheating in the oven or microwave works well; the key is to cover loosely with foil or a microwave-safe lid so the cheese doesn’t dry out.

Freezing

I’ve frozen this casserole successfully by assembling it in a freezer-safe dish, then covering tightly with foil and plastic wrap before freezing. When ready to eat, I thaw it overnight in the fridge and bake it as usual, adding a bit more bake time. The texture is still wonderful and perfect for those nights you want to skip cooking.

Reheating

To reheat leftovers, I preheat my oven to 350°F and warm the casserole uncovered for about 15 to 20 minutes until heated through. This keeps the cheese melty and edges just a little crisp again, which I love. You can also microwave single servings, but I recommend adding a splash of water and covering to maintain moisture.
