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

If you like a little extra richness, you can tuck a few spoonfuls of cream cheese or ricotta into the tortellini mixture before baking, though that will take you beyond the basic three ingredients. For a heartier version, stir in cooked Italian sausage, ground beef, or shredded rotisserie chicken with the sauce and tortellini. If your family enjoys a bit of heat, sprinkle crushed red pepper flakes over the top with the cheese. You can also swap in a different shredded cheese, such as provolone or cheddar, for a slightly sharper flavor. To stretch the dish for a bigger table, add an extra handful of tortellini and a splash of water or broth so there’s enough sauce to go around, then bake a few minutes longer until everything is tender and bubbly.
