Ingredients
1 (12 ounce) box jumbo pasta shells
¼ cup extra-virgin olive oil, divided
1 pound ground sirloin
1 pound Italian sausage, hot or sweet
1 small yellow onion, finely chopped
6 cloves garlic, thinly sliced
1 (26 ounce) jar prepared marinara sauce
1 cup loosely packed fresh basil leaves
½ teaspoon crushed red pepper flakes
1 (15 ounce) container whole milk ricotta cheese

¼ cup heavy whipping cream
1 teaspoon kosher salt
1 ½ cups shredded part-skim mozzarella cheese
cooking spray
Directions
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.

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.

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).

Bake in preheated oven for 30 minutes. Remove from oven and remove foil. Increase oven temperature to broil with rack about 10 inches from heat source; preheat 5 minutes. Return baking dish to oven. Broil until cheese is browned in spots, 5 to 8 minutes.
