Ingredients

Gather these ingredients to create your delicious Mushroom and Spinach Lasagna:

For the Lasagna Layers

  • 9 lasagna noodles
  • 3 cups marinara sauce
  • 2 cups ricotta cheese
  • 1 cup shredded mozzarella cheese
  • ½ cup grated Parmesan cheese

For the Filling

  • 2 tablespoons olive oil
  • 1 onion, finely chopped
  • 3 cloves garlic, minced
  • 1 pound mushrooms (cremini or button), sliced
  • ½ teaspoon dried thyme
  • Salt and pepper, to taste
  • 2 cups fresh spinach leaves, chopped

For Garnish

  • Fresh basil leaves

How to Make Mushroom and Spinach Lasagna

Step 1: Preheat the Oven

Preheat your oven to 375°F (190°C) and grease a 9×13-inch baking dish.

Step 2: Cook Lasagna Noodles

Boil salted water in a pot. Cook the lasagna noodles until al dente according to package instructions. Drain the noodles and set them aside.

Step 3: Prepare Mushroom Filling

Heat olive oil in a skillet over medium heat.
1. Sauté the finely chopped onion for about 3–4 minutes until translucent.
2. Add minced garlic and cook for another minute.
3. Stir in sliced mushrooms, dried thyme, salt, and pepper. Sauté until mushrooms are tender.
4. Add chopped spinach to the mushroom mixture; cook until wilted. Remove from heat.

Step 4: Assemble Lasagna

Spread a layer of marinara sauce on the bottom of the greased baking dish.
1. Lay down 3 lasagna noodles across the sauce.
2. Spread half of the ricotta cheese over the noodles.
3. Layer half of the mushroom filling on top of the ricotta.
4. Sprinkle one-third of mozzarella cheese and half of Parmesan cheese over this layer.
5. Repeat these layers once more—sauce, noodles, ricotta, mushroom filling, mozzarella, and Parmesan—finishing with marinara sauce topped with remaining cheeses.

Step 5: Bake

Cover your assembled lasagna with foil. Bake in the preheated oven for 25 minutes. Remove foil and bake uncovered for an additional 10–15 minutes until cheese is bubbly and golden brown.

Step 6: Serve

Allow your Mushroom and Spinach Lasagna to cool slightly before slicing. Garnish with fresh basil leaves before serving warm.

Enjoy this comforting dish that showcases layers of flavor in every bite!

Mushroom and Spinach Lasagna is a versatile dish that can be enjoyed in various ways. Whether you are hosting a dinner party or enjoying a cozy family meal, these serving suggestions will elevate your dining experience.

Family Style

  • Serve the lasagna directly from the baking dish, allowing guests to help themselves. This creates a warm, communal atmosphere.

Individual Portions

How to Perfect Mushroom and Spinach Lasagna

Creating the perfect Mushroom and Spinach Lasagna requires attention to detail and some helpful tips. Here are some suggestions to ensure your dish turns out flawlessly.

  • Use Fresh Ingredients: Fresh mushrooms and spinach will provide more flavor than frozen counterparts.
  • Don’t Overcook Noodles: Cook lasagna noodles just until al dente to avoid mushiness after baking.
  • Layer Wisely: Alternate layers evenly, ensuring each bite has a balanced mix of cheese, sauce, and filling.
  • Let it Rest: Allow the lasagna to sit for about 10 minutes before serving. This helps it set and makes slicing easier.
  • Customize Cheese: Feel free to mix different cheeses like goat cheese or fontina for added richness.
  • Experiment with Spices: Adjust seasoning and add spices like nutmeg or red pepper flakes for a unique twist.

Best Side Dishes for Mushroom and Spinach Lasagna

Mushroom and Spinach Lasagna pairs well with several delightful side dishes. Here are some great options that complement its flavors beautifully.

  1. Caesar Salad – A classic Caesar salad adds crisp romaine lettuce, crunchy croutons, and creamy dressing for contrast.
  2. Garlic Bread – Warm, buttery garlic bread is perfect for scooping up sauce and adds a satisfying crunch.
  3. Roasted Vegetables – Seasonal roasted vegetables bring color and nutrition to your meal while enhancing taste.
  4. Steamed Broccoli – Lightly steamed broccoli provides a healthy side that balances the richness of the lasagna.
  5. Caprese Salad – Slices of fresh mozzarella, tomatoes, and basil drizzled with balsamic glaze offer freshness.
  6. Antipasto Platter – A selection of cured meats, cheeses, olives, and marinated veggies can serve as an elegant appetizer before the main course.
  7. Mixed Greens – A simple mixed green salad dressed in vinaigrette keeps things light alongside the hearty lasagna.
  8. Pasta Primavera – Lightly sautéed seasonal vegetables tossed with olive oil make for an excellent complementary pasta dish.

Common Mistakes to Avoid

Making Mushroom and Spinach Lasagna can be straightforward, but some common mistakes can affect the final dish. Here are a few to keep in mind:

  • Ignoring the Noodle Cook Time: Cooking lasagna noodles for too long can lead to a mushy texture. Always boil them until al dente before layering.
  • Overstuffing Layers: Adding too much filling can make it hard for the lasagna to cook evenly. Stick to recommended amounts for best results.
  • Skipping the Resting Time: Cutting into the lasagna immediately after baking can cause it to fall apart. Let it rest for at least 10 minutes before serving.
  • Not Seasoning Enough: A lack of seasoning will dull the flavors of your Mushroom and Spinach Lasagna. Taste as you go and adjust salt and pepper accordingly.
  • Using Low-Quality Ingredients: The quality of your cheese and sauce makes a huge difference. Opt for fresh ingredients for a better taste.
