Boil lasagne noodles according to package instructions. Drain well and place them flat to prevent sticking together.

Heat olive oil in a skillet. Add beef and sausage. Cook until browned and fully cooked completely.

Stir onion and garlic into the meat mixture. Cook until onions become soft and fragrant nicely.

Add marinara sauce, tomato paste, Italian seasoning, salt and pepper. Simmer gently for fifteen minutes while stirring occasionally.

Combine ricotta cheese, eggs, parsley and half parmesan cheese in a bowl. Mix until smooth and creamy.

Preheat oven to 375°F. Grease a baking dish lightly with oil or cooking spray before layering ingredients.

Spread a thin layer of meat sauce across the bottom of the baking dish evenly and carefully.

Place lasagne noodles over the sauce layer. Cover the bottom completely without leaving large empty spaces visible.

Spread ricotta mixture over the noodles evenly. Sprinkle mozzarella cheese generously across the entire layer carefully.

Repeat sauce, noodles, ricotta mixture and mozzarella layers until all ingredients are fully used evenly throughout.

Top the final layer with remaining mozzarella cheese and parmesan cheese for golden cheesy baked perfection.

Cover baking dish with foil carefully. Bake for thirty-five minutes until hot and bubbling around the edges.

Take foil off the baking dish. Bake another fifteen minutes until cheese becomes golden and slightly crispy.

Remove lasagne from oven carefully. Let it rest ten minutes before slicing and serving warm for cleaner pieces.
