This oven baked 3-ingredient lazy Alfredo tortellini is the kind of weeknight shortcut that earns a permanent place in your dinner rotation. It turns refrigerated cheese tortellini, jarred Alfredo sauce, and shredded mozzarella into a bubbling casserole with almost no prep, and the oven does nearly all the work. The result is rich, creamy, and deeply comforting, with a browned cheesy top that feels far more special than the effort involved would suggest.
Serve this with a crisp green salad, simple roasted broccoli, or garlic bread to balance the richness of the sauce. If you want to round it out into a heartier meal, a side of sautéed mushrooms, steamed green beans, or a platter of roasted chicken works especially well, and a sprinkle of black pepper or chopped parsley at the table brightens the whole dish.
Oven Baked 3-Ingredients Lazy Alfredo Tortellini
Servings: 4 to 6
Ingredients
1 package (20 ounces) refrigerated cheese tortellini
2 jars (15 ounces each) Alfredo sauce
2 cups shredded mozzarella cheese
Directions
1. Preheat the oven to 375°F and lightly grease a medium casserole dish.
2. Spread a thin layer of Alfredo sauce over the bottom of the dish, then add the tortellini and pour the remaining sauce over the top. Stir gently in the dish so the pasta is evenly coated.
3. Sprinkle the mozzarella evenly over the top, covering the tortellini from edge to edge.
4. Cover the dish with foil and bake for 25 minutes, then uncover and bake for 10 to 15 minutes more, until the sauce is bubbling and the cheese is melted and lightly golden.
5. Let the casserole rest for 5 minutes before serving so the sauce settles slightly and the tortellini stay nicely coated.
6. Spoon onto plates or into shallow bowls and serve hot.
Variations & Tips
Add protein: Stir in cooked shredded chicken, chopped rotisserie chicken, or browned Italian sausage before baking if you want to make this more filling without changing the method much.
Vegetable boost: Add a few handfuls of baby spinach, thawed frozen peas, or lightly steamed broccoli florets to the dish before baking for color and a little freshness.
Cheese finish: Mozzarella gives you that stretchy browned top, but a little grated Parmesan over the casserole before the final bake adds sharper flavor and better browning.
Sauce consistency: If your Alfredo sauce is very thick, add 1/4 to 1/2 cup water or milk before baking so the tortellini stay creamy rather than dry as they heat through.
Make-ahead note: Assemble the casserole a few hours ahead, refrigerate it covered, and add a few extra minutes to the baking time if it goes into the oven cold.
