Preheat your oven to 375°F (190°C).
In a large oven-safe skillet over medium heat, brown the ground beef with diced onion and minced garlic until the meat is no longer pink.
Stir in the crushed tomatoes, dried oregano, Italian seasoning, salt, and pepper. Let it simmer for 5 minutes.
Layer the uncooked lasagna noodles on top of the meat sauce in the skillet, breaking them as needed to fit.
Spoon dollops of ricotta cheese over the noodles and top with one cup of mozzarella cheese.
Pour 3 cups of water or broth over the noodles, ensuring they're mostly submerged.
Cover the skillet with a lid or aluminum foil and bake in the oven for 45 minutes.
Remove the lid or foil, sprinkle the remaining mozzarella and Parmesan cheese on top, and bake for an additional 10-15 minutes until the cheese is melted and bubbly.
Let it rest for 10 minutes before serving, allowing the layers to set.
