Ingredients:
- 1 lb lean ground beef
- 1 tbsp olive oil
- 1 medium yellow onion, finely diced
- 3 cloves garlic, minced
- 24 oz marinara sauce
- 1 tsp dried oregano
- salt to taste
- black pepper to taste
- 15 oz whole-milk ricotta cheese
- 1 large egg, lightly beaten
- 1/4 cup fresh parsley, chopped
- 1/2 tsp salt
- 9 oz no-boil lasagna noodles
- 3 cups shredded low-moisture mozzarella cheese
- 1/2 cup grated Parmesan cheese
Instructions:
- Heat olive oil in a skillet over medium-high heat. Add the ground beef, breaking it apart with a spatula until browned.
- Stir in the diced onion and garlic, sautéing for 3-5 minutes until the onion is translucent.
- Pour in the marinara sauce and oregano. Simmer on low for 5 minutes until the sauce is thick and fragrant.
- In a medium mixing bowl, combine the ricotta cheese, beaten egg, chopped parsley, and salt. Stir until the mixture is smooth.
- Spread a thin layer of meat sauce on the bottom of a 9x13 inch baking dish. Layer 3 noodles side-by-side, followed by 1/3 of the ricotta mixture, a handful of mozzarella, and 1/3 of the meat sauce.
- Repeat the layering process two more times.
- Finish with a final layer of noodles topped with the remaining sauce, mozzarella, and grated Parmesan.
- Cover the dish tightly with aluminum foil. Bake at 375°F (190°C) for 25 minutes.
- Remove the foil and bake for another 15-20 minutes until the cheese is bubbling and golden brown.
- Let the lasagna rest for 15 minutes before slicing to ensure clean layers.
