Ingredients You’ll Need
- 1 19-oz. package frozen cheese tortellini pasta – The heart of this dish, giving it a satisfying and cheesy base without the fuss of making pasta from scratch.
- 8 oz. thick-cut bacon, chopped – Adds a delightful crunch and smoky flavor. Turkey bacon is a great alternative if you prefer something leaner.
- ½ cup unsalted butter – Creates a rich base for the sauce. Use unsalted to control the saltiness of your dish.
- 1 red bell pepper, diced – Offers sweetness and a pop of color; you can swap it with green bell pepper if desired.
- ½ cup diced yellow onions – Enhances the sauce with a savory depth. Don’t skimp on this ingredient!
- 1 tbsp minced garlic – Fresh garlic adds irresistible aroma and flavor. Garlic powder can be a quick substitute.
- ½ cup all-purpose flour – Thickens the creamy sauce. Gluten-free flour can be used for those avoiding gluten.
- 3 cups whole milk – Ensures a rich and smooth sauce. Substitute with half-and-half for extra creaminess.
- 1 cup low-sodium chicken stock – Helps to build flavor in the dish. Vegetable broth is a perfect alternative for a vegetarian version.
- 1½ tsp kosher salt – Essential for taste; adjust to your preference.
- 1½ tsp dried Italian seasonings – A blend of herbs that magically boosts flavor; you can use fresh herbs if available.
- ½ tsp onion powder – Adds more depth; if you love onions, feel free to increase this amount.
- ½ tsp garlic powder – Reinforces garlic flavor; using fresh is great, but powdered is super convenient.
- ½ tsp black pepper – Provides a bit of a kick; feel free to adjust based on your spice tolerance.
- 1½ cups grated Parmesan cheese – The star cheese that melts into the sauce beautifully; Pecorino Romano could be a great substitute.
- 1 12-oz. bag frozen broccoli florets, thawed – Gives a nutritional boost and prevents the casserole from being just pasta.
- 1 12-oz. bag frozen cauliflower florets, thawed – Adds creaminess and texture. You might substitute with green beans!
- 8 oz. fresh mozzarella pearls – Melts into gooey goodness on top; any shredded mozzarella will work, but pearls add a fun touch.
How to Make Cheesy Tortellini Casserole
- Preheat the Oven: Set your oven to 400°F to get it nice and hot while you prepare the casserole.
- Grease the Dish: Spray a 9”x13” casserole dish with nonstick cooking spray to ensure easy serving.
- Cook the Tortellini: In a large pot, cook the frozen cheese tortellini according to package instructions. Drain well and set aside; it’s okay if it’s slightly undercooked as it will finish cooking in the oven.
- Sauté the Bacon: Heat a large, deep skillet over medium-high heat. Once hot, add the chopped bacon. Cook until crispy, then remove the bacon with a slotted spoon. Pat dry with paper towels and set aside.
- Leave Some Grease: Drain excess grease from the pan but leave about 2 tablespoons; this adds wonderful flavor to the sauce.
- Make the Sauce: Add the butter to the skillet and melt it over medium heat. Add the diced bell pepper and onions, sautéing for 4-5 minutes until they soften. Stir in the minced garlic and cook for another 1-2 minutes until fragrant.
- Incorporate the Flour: Sprinkle the flour over the sautéed vegetables and stir until well combined. Sauté for 2 minutes to cook out the raw flour flavor.
- Add Liquids: Gradually pour in the milk and chicken stock while stirring continuously. Cook for about 7-8 minutes until the sauce thickens noticeably.
- Season the Sauce: Add in the salt, Italian seasonings, onion powder, garlic powder, black pepper, and 1¼ cups of grated Parmesan cheese. Stir well to combine all flavors.
- Combine with Veggies and Tortellini: Remove the skillet from heat and gently fold in the thawed broccoli, cauliflower, mozzarella pearls, and the cooked tortellini until everything is well-coated with sauce.
- Transfer to Baking Dish: Pour the mixture into your prepared casserole dish, spreading it evenly.
- Bake Covered: Cover the dish with foil and bake for 20 minutes, ensuring it heats through.
- Add Toppings: Uncover the casserole and sprinkle the remaining grated Parmesan along with the crispy bacon on top.
- Final Bake: Bake uncovered for another 5-6 minutes until the top is golden brown and bubbly.
- Cool Slightly: Allow the casserole to stand for 5-10 minutes to set before serving, making it easier to scoop.
- Serve and Enjoy: Slice up generous portions and get ready for everyone to ask for seconds!
Storing & Reheating
Leftovers of this cheesy goodness can be stored at room temperature for about two hours. For longer storage, place the casserole in an airtight container in the refrigerator for up to 3-4 days. If you’re looking to store it for even longer, you can freeze it for up to 3 months. Ensure it’s well-covered with foil or plastic wrap to prevent freezer burn. When you’re ready to enjoy again, simply reheat individual portions in the microwave for about 2-3 minutes, or warm it in the oven at 350°F until heated through. Just note that the texture may shift slightly after freezing and reheating, but you can refresh it with a sprinkle of extra cheese!
Chef’s Helpful Tips
- To prevent gummy tortellini, cook it al dente as it will absorb moisture during baking.
- Use room temperature ingredients for an even creamier sauce. If using canned or frozen veggies, thaw them beforehand for a more even texture.
- If you want a crispy top, broil the casserole for an additional 1-2 minutes post-baking, but watch closely to prevent burning.
- Don’t shy away from adding your favorite herbs or spices to customize the flavor profile, whether it’s a sprinkle of red pepper flakes or fresh basil.
- This casserole can be assembled a day ahead of time. Cover and refrigerate until you’re ready to bake, making weeknight dinners a breeze.
Cheesy Tortellini Casserole is not just a meal; it’s an invitation to gather, share, and savor.
