Oven Baked 3-Ingredient Sausage Stuffed Shells

Ingredients:

Step-by-Step Directions:

Step 1: Prep the Oven and Glass Casserole Vessel: Preheat your oven to 375°F (190°C). Lightly grease the interior floor and sidewalls of a 9×13-inch glass baking dish with a light coating of butter or oil to prevent the pasta from sticking, then set it aside.

Step 2: Boil the Structural Shells: Bring a large pot of heavily salted water to an aggressive boil. Add your 24 jumbo pasta shells and cook until they are just shy of al dente—exactly 1 / to 2 / minutes less than the package directions.

Tip: Keep the shells slightly firm during this initial boil! This ensures the pasta walls maintain their structural integrity and hold their shape perfectly without tearing while you load the heavy filling.

Step 3: Cool and Arrange the Shells: Drain the jumbo shells thoroughly inside a colander and rinse them briefly under cool water to stop the cooking process immediately. Arrange the cooled shells out in a flat, single layer across a clean baking sheet or large plate so they do not stack or stick together while you prepare the meat core.

Step 4: Sear and Season the Sausage Core: Heat a large skillet over medium heat. Drop in your 1 1/2 pounds of casing-free Italian sausage and cook, breaking it apart into fine crumbles with a wooden spoon, for 7 / to 10 / minutes until beautifully browned with no pink remaining. Carefully spoon off and discard most of the excess rendered fat, leaving just a tiny coating in the pan for optimal moisture.

Step 5: Bind the Cheesy Meat Matrix: Turn off the burner heat and let the crumbled sausage cool down for a few minutes until it is warm but no longer piping hot. Tumble 2 / cups of your shredded mozzarella cheese directly into the skillet. Stir thoroughly until the cheese ribbons soften and begin to cling tightly to the meat, forming a cohesive, chunky, and cheesy filling.

Step 6: Load and Nest the Pasta Pods: Using a spoon or your fingers, pack a generous portion of the sausage-and-cheese mixture into the hollow center of each cooked shell. Arrange the loaded shells neatly in a single layer inside your prepared glass baking dish, nestling them tightly together side-by-side so they stay upright and lock the filling in place.

Step 7: Crown with the Cheese Canopy: Scatter the remaining 2 / cups of shredded mozzarella cheese uniformly over the top of the stuffed shells, creating a heavy, complete cheese blanket that covers the exposed sausage cores.

Step 8: Execute the Two-Stage Bake and Rest: Cover the baking dish loosely with a sheet of aluminum foil, tenting it slightly in the center so it doesn’t touch or pull away the top cheese layer. Bake in the preheated oven for 15 / minutes to heat the interior core through. Carefully remove the foil sheet and continue baking open for another 10 / to 15 / minutes until the top cheese canopy is fully melted, vigorously bubbling, and sports beautiful light golden-brown spots. Pull the dish from the oven and let it rest undisturbed for 5 / minutes to let the matrix set before scooping out steaming portions.
