1 . Stage

Preheat the oven to 375 degrees F (190 degrees C). Set a rack in the center of the oven, about 10 inches from the heat source.

Bring a large pot of salted water to a boil. Add shells and cook, stirring occasionally, until almost tender, about 7 minutes. Drain pasta in a colander. Return to pot and toss with 1 tablespoon oil. Dotdash Meredith Food Studios

Meanwhile, heat remaining 3 tablespoons oil in a large Dutch oven over medium-high heat. Add sirloin and sausage and cook, undisturbed, until bottom side is lightly browned, about 6 minutes. Stir, and continue to cook, stirring and breaking up meat into smaller pieces with a wooden spoon, until cooked through, about 4 minutes. Dotdash Meredith Food Studios

7 . Stage

To assemble, spread about 2 cups of the ragu in the bottom of a 13- x 9-inch baking dish. Spoon 1/2 of the pasta over sauce. Dollop half of the ricotta mixture over pasta, and sprinkle with 1 cup mozzarella cheese. Spoon remaining pasta over mozzarella cheese. Spread remaining ragu over pasta mixture, and dollop with remaining ricotta mixture. Top with remaining 1/2 cup mozzarella cheese. Cover lasagna with a large sheet of aluminum foil that's been lightly sprayed with cooking spray (to prevent the cheese from sticking to it).
