This oven baked 3-ingredients lazy cheddar tortellini is the kind of back-pocket dinner that saves busy weeknights. It leans on store-bought cheese tortellini, shredded cheddar, and pasta sauce to make something warm, filling, and extra cozy with almost no effort. It reminds me of the sort of roommate recipe that gets passed around because it actually works: cheap, easy, and somehow always better than you expect once the top turns golden and bubbly.
Serve it with a simple green salad, roasted broccoli, or garlic bread if you want to stretch it into a fuller meal. It also pairs well with steamed green beans or a handful of fresh basil on top for a little freshness against the rich cheese and sauce.
Oven Baked 3-Ingredients Lazy Cheddar Tortellini
Servings: 4
Ingredients
1 (20 ounce) package refrigerated cheese tortellini
2 cups shredded cheddar cheese
1 (24 ounce) jar pasta sauce
Directions
1. Preheat the oven to 400°F and lightly grease a medium casserole dish.
2. Spread a thin layer of pasta sauce in the bottom of the dish, then add the tortellini and pour the remaining sauce over the top. Stir gently to coat.
3. Sprinkle the shredded cheddar evenly over the top.
4. Bake uncovered for 25 to 30 minutes, until the sauce is bubbling and the cheese is melted with golden edges.
5. Let it rest for 5 minutes before serving so the cheese and sauce can settle slightly.
Variations & Tips
Add a protein: Stir in cooked Italian sausage, shredded rotisserie chicken, or browned ground beef if you want to make it heartier. This is a great way to turn leftovers into a complete one-dish dinner.
Use a different cheese: Mozzarella, Monterey Jack, or an Italian blend all work well here. Cheddar gives it that extra cozy, slightly sharper flavor, but this recipe is very forgiving.
Make it extra saucy: If you like softer pasta bakes with more sauce, add an extra 1/2 to 1 cup of pasta sauce. This also helps if your tortellini absorbs a lot of liquid while baking.
Cover if browning too fast: If the top gets darker before the tortellini is fully heated through, loosely tent the dish with foil for the rest of the bake time. Then uncover it for the last few minutes if you want more color on top.
Meal prep tip: Assemble the casserole earlier in the day, cover, and refrigerate until you're ready to bake. If baking straight from the fridge, add a few extra minutes so the center gets hot all the way through.
