My college roommate showed me this recipe for busy weeknights. It’s so creamy and ready in minutes with just 3 ingredients.

This 3-Ingredient Cheesy Tortellini Bake is the ultimate “emergency dinner” for those nights when you have zero energy but want something that tastes like a homemade Italian feast. By using refrigerated tortellini, you skip the boiling step entirely—the pasta cooks right in the marinara sauce under a foil seal, absorbing all that tomato flavor. It results in plump, tender pasta enveloped in a thick, cheesy “blanket” that rivals any lasagna.

How To Make 3-Ingredient Cheesy Tortellini Bake:

Step 1: Prep the Oven and Dish: Preheat your oven to 400°F. Lightly grease a 9×13-inch white ceramic baking dish.

Tip: Ceramic dishes are excellent for pasta bakes because they retain heat longer than metal, keeping the tortellini warm for seconds (and trust me, people will want seconds).

Step 2: Mix in the Pan: Pour the entire jar of marinara into the dish. Add the refrigerated tortellini and 1 cup of the mozzarella. Stir gently until every piece of pasta is coated.

Note: There is no need to boil the pasta beforehand! The moisture in the sauce will cook the refrigerated dough perfectly.

Step 3: The Cheese Blanket: Spread the mixture into an even layer and sprinkle the remaining 1 cup of mozzarella over the top.

Step 4: The Steam Phase: Cover the dish tightly with foil. Bake for 15 minutes.

Tip: The foil is crucial here—it traps the steam from the sauce, which is what actually “boils” the tortellini inside the oven.

Step 5: The Golden Finish: Remove the foil and bake uncovered for another 10/15 minutes. You want the sauce bubbling vigorously around the edges and the cheese on top to have those beautiful toasted golden-brown spots.

Step 6: The Rest: Let the bake sit for 5 minutes before serving. This allows the sauce to “tighten up” so it clings to the tortellini rather than pooling at the bottom of the plate.
