Preheat oven to 375°F. Line a large sheet pan (approximately 13x18 inches) with parchment paper.

Prepare the meat sauce: Heat olive oil in a large pot or Dutch oven over medium heat. Add ground beef and cook, breaking it apart with a spoon, until browned. Drain any excess fat. Add diced yellow onion and cook until softened, about 5 minutes. Stir in minced garlic and cook for 1 minute until fragrant. Add crushed tomatoes, tomato paste, dried oregano, dried basil, salt, and black pepper. Bring to a simmer, then reduce heat to low, cover, and let it cook while you prepare the noodles and ricotta mixture.

Cook the lasagna noodles: While the sauce simmers, bring a large pot of salted water to a boil. Add the ruffled lasagna noodles and cook according to package directions until al dente. Drain well. Once drained, break the noodles into smaller, irregular pieces (about 2-3 inches long) directly in the pot.

Prepare the ricotta mixture: In a medium bowl, combine ricotta cheese, chopped fresh spinach, grated Parmesan cheese, egg, chopped fresh parsley, salt, and black pepper. Mix until well combined.

Combine base ingredients: Add the prepared meat sauce to the pot with the broken lasagna noodles. Stir thoroughly until the noodles are evenly coated with the sauce.

Assemble on sheet pan: Pour the noodle and meat sauce mixture onto the prepared sheet pan. Spread it out evenly to form a single layer.

Add cheese layers: Sprinkle the shredded mozzarella cheese evenly over the noodle and meat mixture. Then, place dollops of the ricotta cheese mixture strategically over the mozzarella layer.

Bake: Transfer the sheet pan to the preheated oven and bake for 20-25 minutes, or until the cheese is melted and bubbly, and the ricotta is slightly browned in spots. If desired, you can broil for the last 1-2 minutes for extra browning, watching carefully to prevent burning.

Serve: Carefully remove the sheet pan from the oven. Let it rest for a few minutes before serving directly from the pan.
