Ingredients:
Preparing the Lasagna
Sautéing the Vegetables
The foundation of any great lasagna is its filling, and for this recipe, we’re building that flavor with aromatic vegetables. Start by heating the 2 tablespoons of olive oil in a large skillet or Dutch oven over medium heat. Once the oil is shimmering, add the finely chopped onion. We want to sauté the onion until it becomes translucent and begin extracts to soften, which usually takes about 5-7 minutes. This process releases its natural sweetness and creates a lovely base for our dish. Next, stir in the minced garlic and cook for another minute until it’s fragrant. Be careful not to burn the garlic, as it can turn bitter.
Now comes the star of our veggie filling: the mushrooms! Add the sliced pound of mushrooms to the skillet. It might seem like a lot of mushrooms, but they will cook down significantly. Cook the mushrooms, stirring occasionally, until they release their liquid and begin extract to brown. This browning is key to developing their deep, savory flavor. This can take about 8-10 minutes. Sprinkle in the 1/2 teaspoon of dried thyme, and season generously with salt and pepper to taste. The thyme adds a subtle earthy note that pairs beautifully with the mushrooms. Finally, add the 2 cups of chopped fresh spinach to the skillet. Stir it in until it wilts, which will happen quite quickly. Remove the skillet from the heat and set aside.
Preparing the Cheese Mixture
While our vegetable mixture cools slightly, let’s prepare the creamy cheese layer. In a medium bowl, combine the 2 cups of ricotta cheese, 1/2 cup of the grated Parmesan cheese, and about half of the shredded mozzarella cheese (1/2 cup). Season this mixture with a pinch of salt and pepper. Stir everything together until it’s well combined and creamy. This ricotta mixture will add a wonderful richness and tang to every bite of our lasagna. It’s also a good idea to have your remaining 1/2 cup of mozzarella and 1/4 cup of Parmesan cheese ready for topping the lasagna later.
Assembling the Lasagna
Preheat your oven to 375°F (190°C). Now it’s time to assemble our masterpiece! You’ll need a 9×13 inch baking dish. To prevent the lasagna from sticking and ensure even cooking, spread a thin layer of marinara sauce on the bottom of the baking dish. This first layer of sauce also helps to soften the bottom lasagna noodles.
Next, arrange 3 of the lasagna noodles in a single layer over the sauce. You might need to break some noodles to fit them snugly. Spoon about one-third of the ricotta cheese mixture evenly over the noodles, spreading it out to the edges. Then, top the ricotta with about one-third of the sautéed mushroom and spinach mixture. Finally, ladle about one-third of the remaining marinara sauce over the vegetable layer.
Repeat this layering process two more times: noodles, ricotta mixture, mushroom and spinach mixture, and marinara sauce. For the final layer, top the last layer of noodles with the remaining marinara sauce. Make sure the top noodles are well covered in sauce to prevent them from drying out during baking.
Baking the Lasagna
Once your lasagna is fully assembled, it’s time to bake. Cover the baking dish tightly with aluminum foil. This is important to trap the steam and ensure the noodles cook through and become tender. Place the covered lasagna in the preheated oven and bake for 25 minutes.
After 25 minutes, carefully remove the aluminum foil. Sprinkle the remaining 1/2 cup of shredded mozzarella cheese and the remaining 1/4 cup of grated Parmesan cheese evenly over the top of the lasagna. This cheesy topping will melt and turn golden brown, creating a beautiful crust. Return the uncovered lasagna to the oven and bake for another 20-25 minutes, or until the cheese is melted, bubbly, and lightly browned, and the lasagna is heated through.
Resting and Serving
This is perhaps the hardest part, but the most crucial for a perfectly sliced lasagna: let it rest! Once you remove the lasagna from the oven, let it sit uncovered for at least 10-15 minutes. This resting period allows the layers to set, making it much easier to slice and serve without it falling apart. If you cut into it too soon, it will be a delicious but messy affair.
Once rested, cut into generous portions. Garnish with fresh basil leaves for a pop of color and a burst of fresh, herbaceous flavor. This Mushroom and Spinach Lasagna is wonderful served on its own, or with a simple side salad and some crusty bread. Enjoy every comforting, delicious bite!

The possibilities are endless!
Frequently Asked Questions:
Can I make this Mushroom and Spinach Lasagna ahead of time?
Absolutely! You can assemble the entire lasagna up to 24 hours in advance and store it covered in the refrigerator. When you’re ready to bake, simply remove it from the fridge about 30 minutes before baking to allow it to come closer to room temperature, and adjust the baking time slightly as needed, likely adding an extra 10-15 minutes.
What kind of mushrooms are best for this recipe?
A mix of mushrooms adds the most depth of flavor and texture. I recommend using cremini mushrooms for their earthy taste and good texture when cooked. Sautéing them beforehand is crucial to remove excess moisture and concentrate their flavor. You can also include some shiitake mushrooms for a more intense umami kick.
Is this recipe vegetarian?
Yes, this Mushroom And Spinach Lasagna recipe as written is vegetarian. If you’d like to make it vegan, you would need to substitute the ricotta cheese with a cashew-based ricotta or a store-bought vegan ricotta alternative, and ensure your lasagna noodles and sauce are vegan-friendly.
