Ready to layer these ingredients and create a comforting, Mushroom and Spinach Lasagna that your family will adore? Let’s move on to the instructions!
Step‑by‑Step Instructions for Mushroom And Spinach Lasagna
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). This ensures that when your Mushroom And Spinach Lasagna is ready to bake, the temperature is just right for perfectly melting cheese and warming the flavors. While the oven heats, gather all your ingredients and prepped tools, including a 9×13-inch baking dish and a pot for boiling noodles.
Step 2: Prepare the Baking Dish
Grease a 9×13-inch baking dish with olive oil or cooking spray. This step is crucial to prevent your delicious Mushroom And Spinach Lasagna from sticking to the sides as it bakes. Make sure the cover is even, creating an easy way to serve and slice once the dish is done.
Step 3: Cook the Lasagna Noodles
In a large pot, bring salted water to a boil. Once boiling, add the lasagna noodles and cook until al dente, about 8-10 minutes. Drain the noodles and set them aside. This step ensures that your layers maintain their structure while soaking up the flavorful sauces of the Mushroom And Spinach Lasagna.
Step 4: Sauté the Vegetables
In a large skillet, heat a tablespoon of olive oil over medium heat. Add chopped onion and sauté until it becomes translucent, about 3-4 minutes. Stir in minced garlic and cook for another 30 seconds until fragrant. This aromatic base will infuse your Mushroom And Spinach Lasagna with wonderful flavors.
Step 5: Add the Mushrooms and Seasonings
Next, add the sliced mushrooms to the skillet along with dried thyme, salt, and pepper. Sauté for about 5-7 minutes until the mushrooms are tender and release their moisture. This step ensures that the filling is packed with rich, earthy flavors that elevate your Mushroom And Spinach Lasagna.
Step 6: Incorporate the Spinach
Stir in the chopped spinach and cook until just wilted, approximately 2-3 minutes. As the spinach softens, it will blend beautifully with the mushrooms, adding vibrant color and nutrients. This mixture is a star layer in your Mushroom And Spinach Lasagna, contributing both texture and taste.
Step 7: Assemble the First Layer
Spread a thin layer of marinara sauce on the bottom of your greased baking dish, ensuring even coverage. This layer helps keep the lasagna moist as it bakes. Begin layering by placing three lasagna noodles over the sauce. This base will support the hearty filling of your Mushroom And Spinach Lasagna.
Step 8: Add the Filling
Spoon half of the ricotta cheese over the noodles, followed by half of the mushroom and spinach mixture. Sprinkle a mix of mozzarella and Parmesan cheese on top. This layering technique builds a richness that ensures every bite of your Mushroom And Spinach Lasagna is deliciously comforting.
Step 9: Repeat the Layering
Repeat the layering process by adding another set of three noodles, the remaining ricotta cheese, the rest of the mushroom mixture, and another sprinkle of mozzarella and Parmesan. This repetition builds depth and flavor in your Mushroom And Spinach Lasagna, creating a satisfying meal.
Step 10: Final Touches
Top the final noodle layer with the remaining marinara sauce, ensuring all noodles are covered without excess sauce, which could make the dish soggy. Sprinkle additional mozzarella and Parmesan cheese over the sauce for a beautifully golden finish as it bakes.
Step 11: Bake the Lasagna
Cover the baking dish with aluminum foil, creating a tight seal. Bake in the preheated oven for 25 minutes. Then, carefully remove the foil and continue baking for an additional 10-15 minutes until the cheese is bubbly and golden brown. This dual baking method keeps your Mushroom And Spinach Lasagna moist before achieving that lovely golden top.
Step 12: Cool and Garnish
Once baked, remove the Mushroom And Spinach Lasagna from the oven and allow it to cool for about 10-15 minutes. This resting period will let the layers set for easier slicing. Garnish with fresh basil before serving, adding a touch of freshness to this comforting dish.

Expert Tips for Mushroom and Spinach Lasagna
-
Layer Wisely: Ensure each layer is well-seasoned and evenly spread, so every bite of your Mushroom and Spinach Lasagna is bursting with flavor.

Cook Noodles Al Dente: Don’t overcook your lasagna noodles; they should still have a slight firmness to them. This prevents them from becoming mushy after baking.
-
Cover with Foil: Cover the lasagna with foil during the first part of baking to trap moisture. Remove it towards the end to create a beautifully browned cheese top.

Cool Before Slicing: Allow the lasagna to rest for at least 10-15 minutes after baking. This step helps the layers set and makes for easier, cleaner slices.

Minimize Sauce Overload: Be mindful not to overload on sauce. Utilizing a moderate amount prevents a soggy lasagna while still retaining ideal moisture.
