Oven Baked 4-Ingredient Beef Stuffed Shells
Servings: 6
Ingredients
12 jumbo pasta shells
1 pound ground beef
2 cups pasta sauce, divided
2 cups shredded mozzarella cheese, divided
Directions
1. Preheat the oven to 375°F. Cook the jumbo pasta shells in salted boiling water just until al dente according to the package directions, then drain and set aside to cool enough to handle.
2. In a large skillet over medium heat, cook the ground beef until fully browned and cooked through, breaking it up with a spoon as it cooks. Drain off any excess grease.
3. Spread 1 cup of the pasta sauce across the bottom of a white ceramic baking dish. Fill each cooked shell with a spoonful of the browned beef and arrange the shells in the dish.
4. Spoon the remaining 1 cup pasta sauce over the stuffed shells, then sprinkle with the remaining mozzarella cheese.
5. Bake for 20 to 25 minutes, until the cheese is melted and bubbly and the sauce is hot. Let rest for 5 minutes before serving.
Variations & Tips
Add ricotta: If you don't mind moving beyond the 4-ingredient format, a spoonful of ricotta mixed into the beef filling makes the shells creamier and a little more traditional in texture.
Use a flavorful sauce: Since the ingredient list is short, the pasta sauce matters quite a bit. Choose one you already enjoy, because its seasoning will carry much of the finished flavor.
Make-ahead tip: Assemble the shells a day in advance, cover the baking dish tightly, and refrigerate. When ready to bake, add a few extra minutes to the cooking time if the dish is going into the oven cold.
Freezer-friendly version: These shells freeze well before or after baking. Store them in a tightly wrapped dish, then thaw overnight in the refrigerator for easier, more even reheating.
Mini party portions: For appetizer service, keep the shells slightly firmer when boiling so they hold their shape better on a platter. A little extra cheese on top also helps them stay neatly together when served.
