Step‑by‑Step Instructions for Mushroom and Spinach Lasagna

Step 1: Prepare the Vegetables
Heat a large skillet over medium-high heat and add a drizzle of olive oil. Sauté 8 ounces of sliced mushrooms until they turn golden brown and release their juices, about 5-7 minutes. Stir in 6 cups of fresh spinach, cooking until wilted for another 2-3 minutes. Remove from heat and set aside. This will create a delicious base for your Mushroom and Spinach Lasagna.

Step 2: Make the Béchamel Sauce
In a medium saucepan, melt 4 tablespoons of butter over medium heat. Whisk in 4 tablespoons of all-purpose flour, cooking for 2-3 minutes until light golden. Gradually whisk in 3 cups of whole milk, stirring constantly until the sauce thickens and bubbles, around 5-7 minutes. Season with salt, pepper, and a pinch of nutmeg, enhancing the flavors for your creamy Mushroom and Spinach Lasagna.

Step 3: Assemble the Lasagna
Preheat your oven to 375°F (190°C). In a 9×13 inch baking dish, spread a thin layer of béchamel sauce on the bottom. Layer 3 no-boil lasagna noodles over the sauce, then add half of the mushroom and spinach mixture, followed by another layer of béchamel and a sprinkle of 1 cup of shredded mozzarella cheese. Repeat this process, finishing with a final layer of noodles, béchamel, and cheese on top.

Step 4: Bake the Lasagna
Cover the assembled Mushroom and Spinach Lasagna with aluminum foil, being careful not to touch the cheese. Bake in the preheated oven for 30 minutes, allowing the flavors to meld together. Remove the foil and bake uncovered for an additional 15-20 minutes, or until the top is golden brown and bubbly.

Step 5: Cool and Serve
Once baked, take the lasagna out of the oven and let it rest for about 10-15 minutes. This resting time will help the layers set and make slicing easier. Cut into hearty portions and serve warm, allowing the comforting flavors of the Mushroom and Spinach Lasagna to shine.

Make Ahead Options

These Mushroom and Spinach Lasagna layers are perfect for meal prep enthusiasts! You can prepare the filling and béchamel sauce up to 24 hours in advance, refrigerating them separately to maintain their flavors and textures. Simply sauté the mushrooms and spinach, then mix with the béchamel sauce and refrigerate in an airtight container. You can also assemble the lasagna up to 3 days ahead, just remember to cover it tightly with plastic wrap to keep it fresh. When you’re ready to enjoy, bake from the refrigerator, and allow an extra 10 minutes of baking time to ensure it’s heated through and just as delicious!

Variations & Substitutions for Mushroom and Spinach Lasagna

Feel free to dive into creativity and customize your dish with these tasty ideas!

  • Kale Instead of Spinach: Swap out the spinach for kale for a heartier green. Kale brings a unique texture and a slight bitterness that harmonizes beautifully with the creamy béchamel.

  • Nutty Twist: Add a sprinkle of nutmeg to the béchamel for a warm, aromatic depth. It’s a subtle change that adds a sophisticated flavor note to your lasagna.

  • Roasted Veggies: Incorporate roasted zucchini or bell peppers for added layers of flavor. Sweet roasted vegetables complement the earthiness of the mushrooms, making each slice even more delightful.

  • Cheese Upgrades: Mix in ricotta or goat cheese for creaminess. These cheeses can create a beautiful contrast, enriching the creamy texture with their distinct flavors.

  • Gluten-Free Option: Use gluten-free lasagna noodles for a deliciously inclusive meal. Make sure to adjust cooking times, as these noodles may require some extra care.

  • Extra Heat: Add a dash of red pepper flakes to the béchamel for a spicy kick. This simple enhancement can elevate the entire dish, appealing to those who love a little heat.

  • Herb Infusion: Boost freshness by mixing in fresh herbs like basil or thyme into the filling. Their vibrant notes will brighten the comfort of your Mushroom and Spinach Lasagna.

What to Serve with Mushroom and Spinach Lasagna

There’s nothing like a cozy homemade meal to bring friends and family together, especially when it’s a dish as comforting as this lasagna.

  • Garlic Bread: The crispy, buttery crust of garlic bread complements the creamy layers perfectly and adds a delightful crunch to every meal. Plus, it’s great for mopping up any extra béchamel sauce left on the plate!

  • Side Salad: A fresh salad with mixed greens, cherry tomatoes, and a tangy vinaigrette offers a bright contrast to the rich, cheesy lasagna. The freshness of the greens balances out the dish beautifully.

  • Roasted Vegetables: Serve a medley of roasted seasonal vegetables for a burst of flavor; think carrots, zucchini, and bell peppers. Their natural sweetness enhances the earthy flavors of the mushrooms and spinach.

  • Wine Pairing: A light-bodied white wine, like Pinot Grigio, pairs wonderfully with the mushroom and spinach lasagna, enhancing its flavors without overpowering them.

  • Herb-Infused Olive Oil: Drizzling some herb-infused olive oil over your plate adds a fragrant touch, elevating your experience with its fresh burst of flavor.

  • Tiramisu: End the meal with a classic Italian dessert like tiramisu for a sweet finish. Its coffee and cocoa flavors provide a delightful contrast to the lasagna’s savory richness.

  • Pesto Breadsticks: These flavorful twists are perfect for dipping in marinara sauce on the side. Their herby profile complements the spinach beautifully and adds another layer of taste to your meal.

Storage Tips for Mushroom and Spinach Lasagna

Fridge: Store leftover Mushroom and Spinach Lasagna in an airtight container in the refrigerator for up to 3 days. Reheat by covering with foil and baking at 350°F (175°C) until warmed through.

Freezer: For longer storage, freeze individual portions or the entire dish for up to 2 months. Wrap tightly with plastic wrap and then foil to prevent freezer burn.

Reheating: To reheat frozen lasagna, allow it to thaw overnight in the fridge before baking. Bake at 350°F (175°C) until heated completely, usually about 30-40 minutes.

Serving: Always let the lasagna rest for about 10-15 minutes after reheating; this helps the layers stay intact and enhances the overall texture.

Expert Tips for Mushroom and Spinach Lasagna

  • Drain Carefully: Make sure to drain the spinach well if using frozen, to prevent a watery lasagna. Excess moisture can ruin the creamy texture!
  • Layering Technique: Alternate the layers of noodles, béchamel, and filling strategically. Even layers ensure a perfect slice of Mushroom and Spinach Lasagna every time.
  • Rest Before Serving: Let the lasagna sit for 10-15 minutes after baking; this helps the layers settle and makes for cleaner slices.
  • Cheese Choices: Experiment with different cheese combinations for added flavor. A mix of mozzarella and sharp cheddar can elevate your lasagna’s taste.
  • Add Flavor: Consider mixing in other veggies like bell peppers or zucchini for an extra layer of taste without straying from the comfort of the Mushroom and Spinach Lasagna.
