How to Make Mushroom and Spinach Lasagna

Preheat the oven to 375°F (190°C) and grease a 9×13-inch baking dish. This prepares your cooking space and ensures easy removal later!
Cook the lasagna noodles in salted water until al dente, usually about 8-10 minutes. Drain and set them aside, letting them cool slightly to avoid sticking.
Sauté the onion in olive oil over medium heat until it becomes translucent, about 3-5 minutes. Then, add minced garlic and cook for an additional minute for that aromatic flavor.
Add sliced mushrooms, dried thyme, salt, and pepper to the pan. Sauté until the mushrooms are tender, about 5-7 minutes. Stir in fresh spinach and cook until wilted, adding even more nutrients!
Assemble the lasagna by spreading a thin layer of marinara sauce on the bottom of the baking dish. Layer noodles, followed by ricotta, mushroom filling, and mozzarella. Repeat layers, ending with noodles layered with sauce and remaining cheese on top.
Cover the dish with foil and bake for 25 minutes. Remove the foil and bake for an additional 10-15 minutes until the cheese is bubbling and golden brown—yum!
Cool slightly before slicing. Garnish with fresh basil for a beautiful finish and serve warm to keep that cozy vibe alive!

Optional: Serve with a side salad or crispy garlic bread for a complete meal experience.
