This oven baked 3-ingredients creamy tomato tortellini is one of those weeknight miracles I picked up from my sister, and it truly is absolutely divine for how little effort it takes. It’s the kind of spring dinner you can throw together after work while the kids finish homework, and it still feels special enough for a Sunday table. Everything bakes together in one glass casserole dish until the cheese turns golden and bubbly, the tomato sauce mellows into a pretty blush pink, and the tortellini stay tender and cozy in their creamy bath.
Serve this creamy tomato tortellini straight from the glass casserole dish with a big green salad (spring mix, cucumbers, and a simple vinaigrette work nicely) and some warm crusty bread or garlic toast to scoop up the extra sauce. A side of roasted asparagus or green beans makes it feel extra springy. For kids, I like to add a small bowl of apple slices or carrot sticks on the side—it rounds out the plate without much extra work.
Oven Baked 3-Ingredients Creamy Tomato TortelliniServings: 4
Ingredients
1 (20–24 oz) package refrigerated cheese tortellini
1 (24 oz) jar tomato pasta sauce (your favorite marinara or tomato basil)
1 1/2 cups heavy cream (or half-and-half for a lighter version)
2 cups shredded mozzarella cheese, divided (this is included as part of the 3 main ingredients: pasta, sauce + cream, cheese)
Directions
Preheat your oven to 375°F (190°C). Lightly grease a 9x13-inch glass casserole dish so the pasta doesn’t stick.
In a large bowl or directly in the casserole dish, whisk together the tomato pasta sauce and heavy cream until the color turns a smooth blush pink.
Add the refrigerated cheese tortellini to the creamy tomato sauce and stir gently until every piece of pasta is well coated. Spread the mixture into an even layer in the glass casserole dish.
Sprinkle 1 1/2 cups of the shredded mozzarella evenly over the top, reserving the remaining 1/2 cup for later.
Cover the casserole dish tightly with foil and bake for 20 minutes, until the sauce is hot and the tortellini are just tender.
Carefully remove the foil, sprinkle the remaining 1/2 cup mozzarella over the top, and return the dish to the oven uncovered.
Bake for another 10–15 minutes, or until the cheese on top is melted, golden in spots, and the sauce is bubbling gently around the edges.
Let the tortellini rest for 5–10 minutes before serving so the sauce can thicken slightly and the cheese sets just enough. Serve warm straight from the glass casserole dish, scooping down to get plenty of pasta, creamy tomato sauce, and that golden cheesy top in every serving.
Variations & Tips
To keep this truly in the spirit of a simple 3-ingredient spring dinner, think of the categories as pasta, creamy tomato sauce, and cheese—then play within those. For a lighter version, use half-and-half instead of heavy cream and part-skim mozzarella. If your family likes a little extra protein, you can stir in some cooked, sliced chicken sausage or rotisserie chicken before baking (this would make it more than 3 ingredients, but it’s a nice add-on for heartier appetites). For picky eaters, use a very smooth tomato sauce with no chunks and cut any larger tortellini in half before baking so they’re easier for little mouths. You can also sprinkle just a thin layer of cheese on top if you have kids who don’t like a super cheesy crust. To sneak in veggies, stir in a handful of baby spinach or some thawed, well-drained frozen peas; they’ll soften nicely in the sauce. Food safety tips: Keep the tortellini refrigerated until you’re ready to bake, and don’t leave the finished casserole at room temperature for more than 2 hours. If you add any meat, make sure it’s fully cooked before mixing it in. Leftovers should be cooled quickly, stored in an airtight container in the refrigerator, and eaten within 3–4 days; reheat until steaming hot all the way through before serving.
