How to Make Tortellini Casserole

1
Preheat your oven to 375 F (190 C). This will ensure that your casserole cooks evenly and at the right temperature.
2
Cook the tortellini according to the package instructions until it's al dente. This should take about 5-7 minutes, depending on the brand and type of pasta you're using.
3
In a large skillet or saute pan, heat the olive oil over medium-high heat. Add the chopped onion and cook until it's translucent, about 3-4 minutes.
4
Add the minced garlic and cook for an additional 1-2 minutes, until it's fragrant. Be careful not to burn the garlic, as it can quickly become bitter.
5
Add the marinara sauce to the skillet and stir to combine. Bring the sauce to a simmer and let it cook for a few minutes until it's heated through.
6
In a large bowl, combine the cooked tortellini, marinara sauce, and chopped onion mixture. Stir to combine and season with salt and pepper to taste.
7
In a separate bowl, combine the grated mozzarella and parmesan cheese. You can also add some chopped fresh herbs like parsley or basil if you prefer.
8
In the prepared 9x13 inch baking dish, create a thin layer of the marinara sauce on the bottom. This will help prevent the casserole from sticking to the dish.
9
Add a layer of the tortellini mixture on top of the sauce, followed by a layer of the cheese mixture. Repeat this process until you've used up all of the ingredients, ending with a layer of cheese on top.
10
Cover the dish with aluminum foil and bake for 25-30 minutes, until the casserole is hot and the cheese is melted.
11
Remove the foil and continue baking for an additional 10-15 minutes, until the top is golden brown and the casserole is heated through.
12
Remove the casserole from the oven and let it rest for a few minutes before serving. This will help the cheese set and the flavors to meld together.
