My neighbor brought this over and I couldn't believe how good it was, seriously only 3 ingredients

This oven baked 3-ingredients sheet pan tortellini is exactly the kind of neighborly surprise that makes my whole week. My neighbor walked over with a foil-lined pan of these cheesy, saucy tortellini and I honestly didn’t believe her when she said it was only three ingredients. Everything toasts and melts together in the oven so you get crispy edges on the tortellini, pockets of gooey mozzarella, and a rich red sauce coating every bite. It’s a busy-night lifesaver: no boiling pasta, almost no cleanup, and it feels like real comfort food after a long day at work.

Serve this straight from the foil-lined sheet pan with a big spoon and let everyone scoop their own portion. It’s great with a simple green salad (bagged is totally fine) and some garlic bread or a sliced baguette to soak up the extra sauce and melted cheese. If you want to stretch it a bit further, add a side of roasted veggies you can cook on a separate rack while the tortellini bakes. A glass of red wine, sparkling water with lemon, or even a cold beer all pair nicely with the cozy, cheesy, tomato flavors.

Servings: 4

1 (20–24 oz) bag refrigerated cheese tortellini

Preheat your oven to 400°F (200°C). Line a rimmed sheet pan with aluminum foil for easy cleanup, making sure the foil goes up the sides a bit to catch any sauce.

Pour about half of the jarred marinara sauce onto the foil-lined sheet pan and spread it into an even layer to lightly coat the bottom.

Add the refrigerated cheese tortellini directly onto the sheet pan (no need to boil them first). Spread them into a mostly even single layer over the sauce.

Drizzle or spoon the remaining marinara sauce evenly over the tortellini, using a spoon or clean hands to gently toss and coat most of the pieces in sauce while keeping them in a single, even layer.

Sprinkle the shredded mozzarella cheese evenly over the top of the sauced tortellini, making sure most of the pasta is covered but leaving a few edges exposed so they can get toasty.

Place the sheet pan on the middle oven rack and bake for 18–22 minutes, until the sauce is bubbling around the edges and the cheese is fully melted.

For extra toasty, browned spots on the cheese and crispy edges on the tortellini, switch the oven to broil on high for 2–3 minutes at the end, watching closely so it doesn’t burn.

Remove the sheet pan from the oven and let the tortellini rest for 5 minutes so the cheese can set slightly and the sauce thickens a bit. Serve straight from the pan while hot.

If you want to keep the spirit of the three-ingredient magic but tweak it a little, you can play around within each ingredient category. Try different flavors of refrigerated tortellini like spinach and cheese or three-cheese blends for a slightly different taste without changing the process. Swap the marinara for a spicy arrabbiata or a roasted garlic tomato sauce if your family likes a little kick. Use a mozzarella blend (like an Italian cheese mix) instead of straight mozzarella for more flavor while still counting it as your one cheese ingredient. For meal prep, assemble the whole sheet pan earlier in the day, cover it, and refrigerate; when you get home, just bake as directed, adding a few extra minutes if it’s going in cold. To avoid sticking or dryness, make sure most of the tortellini are at least lightly coated in sauce before baking, and don’t skip the foil—it keeps cleanup to a quick crumple-and-toss so this really does feel like a neighbor-dropped-off dinner even when you made it yourself.
