Step‑by‑Step Instructions for Creamy Spinach Mushroom Lasagna

Step 1: Prepare the Béchamel
In a medium saucepan, melt 4 tablespoons of butter over medium heat. Whisk in ¼ cup of flour to create a roux, cooking for about 2 minutes until it turns a light golden color. Gradually whisk in 3 cups of milk, stirring constantly until the mixture thickens and bubbles, approximately 5–7 minutes. Add a pinch of nutmeg for warmth, then remove from heat and set aside.

Step 2: Sauté the Vegetables
In a large skillet, heat 2 tablespoons of olive oil over medium heat. Add 3 cloves of minced garlic and sauté until fragrant, about 1 minute. Toss in 8 ounces of sliced mushrooms, cooking until they are browned and tender, around 5 minutes. Finally, add 5 ounces of fresh spinach, stirring until just wilted, approximately 2 minutes, then remove from heat.

Step 3: Layer 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. Place a layer of lasagna noodles over the sauce, followed by half of the sautéed mushroom and spinach mixture. Sprinkle with a layer of cheese and repeat the process until all ingredients are used, finishing with a top layer of béchamel and cheese.

Step 4: Bake the Lasagna
Cover the baking dish with aluminum foil, ensuring it’s tight so steam stays inside. Bake in the preheated oven for 30 minutes, allowing the flavors to meld and the sauce to bubble. After 30 minutes, carefully remove the foil and bake uncovered for an additional 15 minutes, or until the top is golden brown and bubbling.

Step 5: Rest & Serve
Once out of the oven, let your creamy spinach mushroom lasagna rest for about 10 minutes. This cooling period allows the layers to set, making slicing easier. When ready, cut into squares and serve warm, maybe garnished with fresh herbs for that added touch.

How to Store and Freeze Creamy Spinach Mushroom Lasagna

Refrigerator: Store leftover creamy spinach mushroom lasagna in an airtight container for up to 3 days. Reheat individual portions in the microwave or in a low oven until warmed through.

Freezer: For longer storage, wrap the lasagna tightly in plastic wrap and then in aluminum foil. It can be frozen for up to 3 months. Thaw overnight in the fridge before reheating.

Reheating: When reheating, cover with foil to retain moisture. Bake at 350°F (175°C) for about 30 minutes or until heated through, ensuring it remains creamy and delicious.

Make-Ahead: You can prepare the lasagna a day in advance, store it in the fridge, and just bake it on the day of serving for a quick and comforting meal.

Expert Tips for Creamy Spinach Mushroom Lasagna

Béchamel Consistency: Ensure your béchamel is thick enough—it should not be runny. This is crucial for the layers to hold together in your creamy spinach mushroom lasagna.
Cheese Choices: Mix different cheeses! While mozzarella is delightful, adding ricotta or goat cheese can elevate the flavor profile and add creaminess.
Vegetable Variety: Don’t shy away from adding more veggies like zucchini or artichokes for a burst of flavor and texture, while keeping the dish hearty.
Season Generously: Taste as you go! Proper seasoning with salt and pepper enhances all the flavors, so adjust to your preference before layering the lasagna.
Make-Ahead Option: Prepare this dish in advance! You can assemble it a day ahead, store it in the fridge, and then bake it right before serving.
Resting Is Key: Let the lasagna sit for about 10 minutes after baking. This allows it to set perfectly for clean, delicious slices.

Make Ahead Options

These Creamy Spinach Mushroom Lasagna are perfect for busy home cooks looking to save time! You can prepare the entire lasagna (up to 24 hours in advance) by assembling it in your baking dish, then cover it tightly with foil and refrigerate. This method allows the flavors to meld beautifully while also preserving the quality of each layer. Alternatively, you can prepare the béchamel sauce and sauté the vegetables a few days ahead (up to 3 days), storing them separately in the refrigerator. When you’re ready to bake, simply layer everything and cook as directed. You’ll enjoy this comforting dish with minimal effort on your busy weeknights!
