A lighter, herb-free alternative to classic lasagna, this creamy spinach white lasagna features layers of ricotta, Alfredo sauce, and sautéed spinach, making it a comforting and family-friendly dish.
Preheat the oven to 375°F (190°C). Lightly oil or spray a 9x13-inch baking dish.
Cook the lasagna noodles according to package directions until al dente. Drain and lay them flat on a lightly oiled sheet to prevent sticking.
Heat 1 tablespoon olive oil in a skillet over medium heat. Add the spinach and sauté just until wilted — about 1 to 2 minutes. Remove from heat and let any excess liquid evaporate.
In a medium bowl, combine the ricotta cheese, garlic powder, salt, and black pepper. Stir until smooth.
Assembly
Spread a thin layer of Alfredo sauce across the bottom of the prepared baking dish (about 1/2 cup).
Place 3 lasagna noodles over the sauce. Spoon half of the ricotta mixture over the noodles and spread evenly. Sprinkle half of the mozzarella and scatter half of the wilted spinach.
Repeat the layering: 3 noodles, remaining ricotta, remaining mozzarella, remaining spinach. Top with the final 3 noodles.
Spread the remaining Alfredo sauce over the top layer of noodles and sprinkle with the remaining mozzarella. Finish with the grated Parmesan.
Baking
Cover the dish tightly with foil and bake for 25 minutes.
Remove foil and continue baking for an additional 15 minutes until the top is golden and the cheese is bubbling.
Serving
Let the lasagna rest for 10 minutes before slicing to help the layers set.
Notes
For best texture and to prevent a watery lasagna, pat spinach dry after sautéing. You can make this ahead of time and store in the fridge or freezer.
