Step‑by‑Step Instructions for Mushroom And Spinach Lasagna
Step 1: Preheat and Prepare
Begin by preheating your oven to 375°F (190°C) and greasing a 9x13-inch baking dish with a light coating of olive oil. This ensures the Mushroom and Spinach Lasagna won’t stick, allowing for easy serving later on. Gather all your ingredients so you have everything within reach for a smooth cooking process.
Step 2: Cook the Noodles
Fill a large pot with water, adding a generous amount of salt, and bring it to a boil over high heat. Once boiling, carefully add the lasagna noodles and cook according to package instructions until they’re al dente, typically about 8–10 minutes. Drain the noodles and set them aside on a baking sheet to prevent sticking while you prepare the filling.
Step 3: Sauté the Aromatics
In a large skillet, heat 2 tablespoons of extra virgin olive oil over medium heat. Once the oil is shimmering, add the chopped onion and sauté for about 3–4 minutes, or until it becomes translucent. The aroma will fill your kitchen, setting the stage for the delicious flavors to come in your Mushroom and Spinach Lasagna.
Step 4: Add the Garlic and Mushrooms
Stir in the minced garlic, cooking for an additional minute until fragrant. Then, add the sliced mushrooms, dried thyme, salt, and pepper to the skillet. Cook the mixture for about 5–7 minutes, stirring occasionally, until the mushrooms are tender and most of their moisture has evaporated, which intensifies their flavor.
Step 5: Incorporate the Spinach
Add the fresh spinach to the skillet and cook until wilted, which should take about 2–3 minutes. Stir the mixture well to blend all the flavors together. This vibrant filling will be layered throughout your Mushroom and Spinach Lasagna, bringing both color and nutrition to the dish.
Step 6: Assemble the Layers
Start assembling your lasagna by spreading a thin layer of marinara sauce on the bottom of the greased baking dish. Then, place three lasagna noodles on top. Next, spread half of the ricotta cheese over the noodles, followed by half of the mushroom and spinach mixture. Top with a sprinkle of a third of the mozzarella and Parmesan cheeses.
Step 7: Repeat the Layers
Repeat the layering process, starting again with three more noodles. Place the remaining ricotta and the rest of the mushroom and spinach mixture on top, along with another third of the mozzarella and Parmesan. Finish with a final layer of noodles on top, ensuring everything is evenly distributed in your Mushroom and Spinach Lasagna.
Step 8: Final Topping and Bake
Spread the remaining marinara sauce over the top layer of noodles, then sprinkle with the remaining mozzarella and Parmesan cheese. Cover the baking dish securely with aluminum foil to prevent the top from burning. Bake in the preheated oven for 25 minutes; then, uncover and bake an additional 10–15 minutes until the cheese is bubbly and golden brown.
Step 9: Cool and Serve
Once baked, remove the Mushroom and Spinach Lasagna from the oven and let it cool for about 10 minutes before serving. This resting time allows the layers to set, making it easier to slice. Garnish with fresh basil for an aromatic touch and enjoy the comforting flavors of this delicious dish!

How to Store and Freeze Mushroom And Spinach Lasagna
Fridge: Store leftovers in an airtight container for up to 3-4 days to keep your delicious Mushroom and Spinach Lasagna fresh and flavorful.

Reheating: When ready to enjoy, thaw in the fridge overnight, then bake at 375°F (190°C) until heated through, about 30-40 minutes.
