A delicious and healthier take on the classic lasagna, packed with flavor and nutrients.
Preheat your oven to 350°F (175°C).
Preheating ensures even cooking from the start.
Cook the lasagna noodles according to the package instructions, then drain and set aside.
Add a bit of oil to the boiling water to prevent sticking.
In a skillet, cook the ground beef until browned, then drain any excess fat.
Break the beef into small pieces for even cooking.
Sauté the onions and mushrooms in a pan until softened, then add the soy sauce and vinegar.
Cook until the liquid is mostly evaporated for concentrated flavor.
Mix the ricotta cheese, one cup of mozzarella, and the egg in a bowl.
Ensure the mixture is smooth for easy spreading.
Layer the lasagna in a baking dish: start with a layer of tomato sauce, followed by noodles, cheese mixture, beef, and spinach. Repeat until all ingredients are used, ending with a layer of sauce.
Press each layer gently to compact the lasagna.
Cover the dish with foil and bake for 45 minutes. Remove the foil, sprinkle the remaining mozzarella on top, and bake for another 15 minutes.
Let the lasagna rest for 10 minutes before serving to set the layers.
Serve the lasagna warm, garnished with fresh basil if desired.
Pair with a side salad for a complete meal.
