Ingredients
Method
- Brown the ground beef with onion in olive oil over medium-high heat, about 8 minutes. Add garlic, cook 1 minute, drain fat, stir in marinara, and simmer for 5 minutes.
- Mix ricotta, egg, 1 cup mozzarella, ¼ cup Parmesan, Italian seasoning, salt, and pepper until combined.
- Spread a thin layer of sauce in a 9x13-inch dish. Layer half the frozen ravioli, half the ricotta mixture, half the remaining sauce, and ½ cup mozzarella.
- Repeat with remaining ravioli, ricotta, and sauce. Top with remaining mozzarella and Parmesan. Cover with foil and bake at 375°F for 20 minutes, then uncover and bake 15-20 minutes until bubbly and golden.
- Rest 10 minutes, slice into squares, and serve warm with fresh basil or extra Parmesan.
Notes
Assembling the lasagna a day ahead works great; just add 10 minutes to the covered bake time if it goes into the oven cold. The 10-minute rest after baking is what keeps each slice neat, so don’t skip it.
