Ingredients Method Notes

Ingredients
  

  • 1 lb lean ground beef
  • 1/2 medium yellow onion diced
  • 3 cloves garlic minced
  • 24 oz marinara sauce
  • 8-10 oven-ready lasagna noodles
  • 15 oz whole milk ricotta cheese
  • 2 cups mozzarella cheese shredded, divided
  • 1/2 cup Parmesan cheese grated
  • 1 large egg
  • 1 tsp Italian seasoning
  • 1/2 tsp kosher salt
  • 1/4 tsp black pepper

Method
 

  1. Place the cast iron skillet over medium-high heat. Cook the ground beef and diced onions until the meat is browned. Drain excess fat.
  2. Add the minced garlic and cook for 1 minute. Stir in the marinara sauce and simmer for 5 minutes.
  3. In a separate bowl, mix the ricotta, egg, 1/2 cup of mozzarella, Parmesan, Italian seasoning, salt, and pepper until smooth.
  4. Scoop out two-thirds of the meat sauce from the skillet and set aside, leaving a thin layer on the bottom. Remove skillet from heat.
  5. Break noodles to fit the skillet and place a layer over the bottom sauce.
  6. Spread half of the ricotta mixture over the noodles, then top with half of the reserved meat sauce.
  7. Repeat the layers: noodles, remaining ricotta, remaining meat sauce.
  8. Preheat oven to 375°F (190°C). Top the lasagna evenly with the remaining 1.5 cups of mozzarella cheese.
  9. Cover the skillet tightly with foil (spray the underside with non-stick spray) and bake for 30 minutes.
  10. Remove foil and bake for another 10-15 minutes until the cheese is golden and bubbling.
  11. Let the lasagna rest for 15-20 minutes before slicing and serving.

Notes

Skillet Care: Wash the cast iron skillet relatively soon after dinner to prevent the acidic tomato sauce from sitting on the metal overnight. Dry thoroughly and rub with a light coat of oil.
