Classic Lasagna with Meat Sauce

Preheat oven to 375°.

Combine ricotta, 2 ounces (about 1/2 cup) mozzarella, 2 tablespoons parsley, butter, oregano, 1 garlic clove, and egg; set aside.

Place ground beef in a large non­stick skillet over medium-high heat; sprinkle with peppers and remaining 4 garlic cloves. Cook for 9 minutes or until beef is browned, stirring to crumble; drain. Return beef mixture to pan; stir in marinara sauce, and remove from heat.

Spread 1/2 cup meat sauce in bottom of a broiler-safe 11 x 7–inch glass or ceramic baking dish coated with cooking spray. Cut bottom third off each noodle to form 6 long and 6 short noodles; cut short noodles in half to form 12 pieces. Arrange 2 long noodles along outside edges of dish; arrange 4 short noodle pieces along center of dish.

Top noodles with 1 cup meat sauce. Top with 2 long noodles and 4 short noodle pieces, all of ricotta mixture, and 1 cup meat sauce. Arrange remaining 2 long noodles and 4 short noodle pieces on top. Spread remaining meat sauce over top noodles. Sprinkle evenly with remaining 4 ounces (1 cup) mozzarella cheese and Parmigiano-Reggiano cheese. Cover with foil coated with cooking spray.

Bake at 375° for 30 minutes. Uncover and bake for an additional 10 minutes or until bubbly.

Preheat broiler to high. (Keep lasagna in oven.)

Broil lasagna for 1 to 2 minutes or until cheese is golden brown and sauce is bubbly. Remove from oven; let stand 10 minutes. Sprinkle with remaining 2 tablespoons parsley; cut into 6 pieces.
