  • 1 large sweet onion diced
  • 1 tablespoon Olive oil
  • 1 lb lean ground beef
  • 1 lb sweet or hot Italian sausage
  • 1 tablespoon Italian seasoning (Plus, 1 tsp) divided
  • 1 teaspoon garlic salt
  • 1 teaspoon red pepper flakes
  • 1 16 oz container ricotta cheese
  • 1 large egg beaten
  • ¼ cup grated Parmesan cheese
  • 1 12 oz box dry lasagna noodles
  • 1 67 oz jar marinara sauce (I.e. Prego)
  • ¼ cup tomato paste
  • 30 pepperoni slices
  • 4 cups shredded mozzarella cheese divided
  • Fresh basil for garnishing


  • Drizzle a large skillet with olive oil. Cook the onion over medium-high heat until translucent about 3 minutes.
  • Add the ground beef and sausage to the pan. Add 1 tablespoon Italian seasoning, garlic salt and red pepper flakes.
  • Cook over medium-high until no pink remains. Drain any excess fat from the pan.
  • Add the marinara sauce and tomato paste. Cook stirring just until the tomato paste has dissolved. Remove from the heat. (This can be done in advance and chilled until assembling)
  • In a small mixing bowl mix together the ricotta, beaten egg, grated Parmesan and remaining 1 teaspoon Italian seasoning.
  • To assemble: Spray the crock of a 6-quart oval slow cooker with cooking spray. Spread 1 cup meat sauce sauce on the bottom from edge to edge. Arrange 3 lasagna noodles in a single layer over the sauce. Break to fit as needed.
  • Spread noodles with ⅓ of the ricotta, ⅓ of the meat sauce, 1 cup shredded cheese.
  • Arrange 10 pepperoni slices over the cheese. Repeat 2 more times.
  • End with the 4th layer of noodles and cover liberally with sauce.
  • Cover and cook on low for 4-6 hours. (See Cook's note)
  • Uncover and top with remaining 1 cup cheese. Cover and let rest just until cheese melts. Let stand uncovered for 10 minutes.
  • Garnish with fresh basil, if desired. Cut and serve.


  • The entire lasagna may be assembled in the removable crock in advance then covered and chilled until cooking.  Check the manufacturers recommendation for your particular unit for safety.
  • If assembling with hot meat sauce and cooked immediately check for doneness at 4 hours.
