Gather Your Ingredients
- Nine lasagna noodles: choose good quality dried noodles for even cooking
- Two tablespoons olive oil: adds richness and enhances sautéed veggies
- One onion, finely chopped: provides a sweet and savory base
- Three cloves garlic, minced: essential for depth of flavor
- One pound mushrooms, sliced: cremini or button mushrooms give earthiness and texture
- Half teaspoon dried thyme: adds a subtle herbaceous note pick fresh or well-sealed dried thyme for best taste
- Salt and pepper to taste: use sea salt if possible for a cleaner seasoning
- Three cups marinara sauce: choose a simple high-quality tomato sauce for bright acidity
- Two cups ricotta cheese: creamy layer that balances the tangy tomato

- Half cup grated Parmesan cheese: sharp and nutty accent
- Two cups fresh spinach leaves, chopped: adds color, nutrients, and mild flavor
- Fresh basil leaves for garnish: brightness and freshness to finish the dish
How to Make It
- Sauté the Aromatics:
- Heat olive oil in a large skillet over medium flame. Add finely chopped onion and cook for about three to four minutes until translucent and fragrant. Stir in minced garlic and continue cooking for an additional minute so the flavors meld without burning.
- Cook the Mushrooms and Spinach:
- Add the sliced mushrooms to the skillet with dried thyme, salt, and pepper. Sauté until mushrooms are tender and all released moisture evaporates, which concentrates their umami flavor. Toss in the chopped spinach and cook down for two to three minutes until wilted. Remove from heat.
- Prepare the Pasta:
- Fill a large pot with salted water and bring it to a rolling boil. Add lasagna noodles carefully to avoid breaking them. Cook according to package directions until al dente which usually takes around eight to ten minutes. Drain noodles and lay them flat or in a single layer on a clean kitchen towel to prevent sticking.
- Assemble the Lasagna:
- Preheat oven to 375 degrees Fahrenheit (190 degrees Celsius). Lightly grease a nine by thirteen inch baking dish with olive oil or cooking spray. Spread a thin layer of marinara sauce at the bottom to prevent noodles sticking to the dish. Lay three lasagna noodles side by side on the sauce. Spread half of the ricotta cheese evenly over the noodles. Spoon half of the mushroom and spinach mixture on top and distribute it evenly. Sprinkle a third of the mozzarella and Parmesan cheese over the top. Repeat layers with remaining noodles, ricotta, mushroom mixture, and cheeses. Finish with a generous layer of marinara sauce on top.
- Bake the Lasagna:
- Cover the dish tightly with aluminum foil and place it in the preheated oven. Bake for 25 minutes to heat everything through and allow flavors to meld. Remove foil carefully and continue baking for another 10 to 15 minutes until the cheese on top melts and turns golden brown and bubbly.
My favorite ingredient here has to be the mushrooms. They soak up flavors beautifully and give this vegetarian dish a meaty texture without heaviness. I remember making this for my family when a friend brought over fresh mushrooms from a local farm. The dish felt extra special that night and has since been a beloved repeat on our table.
Flavor Boosters
Store any leftover lasagna covered tightly in the refrigerator for up to four days. Reheat in the oven or microwave until warmed through. To freeze, portion into airtight containers and freeze for up to three months. Thaw in the refrigerator overnight before reheating.
Serving Suggestions
Pair the lasagna with a simple mixed green salad dressed with lemon vinaigrette to cut through the richness. Serve alongside garlic bread or toasted baguette slices to soak up extra sauce. A light sparkling water with lemon or an Italian red wine like Chianti complements the flavors well.
Creative Twists
Swap ricotta for cottage cheese for a lighter texture. Use kale or Swiss chard instead of spinach for a heartier green. Substitute shredded cheddar or Gruyère cheese for mozzarella for a new flavor twist. Try a jarred roasted red pepper sauce instead of marinara for a smoky profile.
This lasagna delivers hearty flavor and comforting textures that delight all ages.
Common Questions About the Recipe
- → What type of mushrooms work best in this dish?
Cremini or button mushrooms are ideal for their firm texture and earthy flavor, which complement the spinach and cheeses well.
- → Can I prepare the filling in advance?
Yes, sauté the mushrooms and spinach beforehand and store them in the refrigerator. Assemble and bake just before serving for best freshness.
- → Is it necessary to cook the noodles before layering?
Yes, boiling the lasagna noodles until al dente ensures they soften properly during baking and blend smoothly with the layers.
- → How can I achieve a bubbly and golden top?
Baking covered initially locks in moisture, then uncovering in the final 10-15 minutes allows the cheese to bubble and brown nicely.

Dried thyme adds subtle earthiness to the mushrooms, while fresh basil leaves garnish the finished dish with fragrant brightness.
