🥬 Ingredient Swaps and Additions

Cheese choices: Fontina, Gruyère, or provolone all melt beautifully here.

👩‍🍳 How to Make Creamy Spinach Mushroom Lasagna

Step 1: Prepare the Veggies

In a large skillet, heat olive oil over medium heat. Sauté onions until translucent, then add garlic and mushrooms. Cook until mushrooms are tender and golden (about 8–10 minutes). Add the spinach and cook just until wilted. Season with salt and pepper. Set aside.

Step 2: Make the Béchamel Sauce

In a medium saucepan, melt butter over medium heat. Whisk in the flour and cook for 1–2 minutes. Slowly whisk in the milk, stirring constantly to avoid lumps. Cook until thickened (about 5–7 minutes). Season with salt, pepper, and a pinch of nutmeg. Remove from heat.

Step 3: Assemble the Lasagna

Preheat oven to 375°F (190°C). In a greased 9×13-inch baking dish, spread a thin layer of béchamel. Layer in the following order: noodles, béchamel, ricotta (if using), mushroom-spinach mixture, shredded mozzarella, and a sprinkle of Parmesan. Repeat layers, finishing with sauce and cheese on top.

Step 4: Bake to Perfection

Cover the dish with foil and bake for 25 minutes. Uncover and bake an additional 15–20 minutes, until bubbly and golden. Let rest 10 minutes before slicing.

🍷 What to Serve with It

• Garlic bread or focaccia – to mop up all that creamy sauce!
• Simple arugula salad – with lemon vinaigrette to cut the richness.
• Roasted vegetables – like carrots or zucchini for a seasonal touch.
• A crisp white wine – such as Sauvignon Blanc or Pinot Grigio.

🌟 Tips for the Best Spinach Mushroom Lasagna

Drain your spinach well to avoid watery lasagna.
Use no-boil noodles to save time, but make sure your sauce is slightly looser to help cook them.
Grate your own cheese for the best melt and flavor—pre-shredded often has anti-caking agents.
Let it rest after baking! It sets better and slices cleanly.

🧊 Storage and Make-Ahead Tips

Fridge: Store leftovers in an airtight container for up to 4 days.
Freezer: Freeze unbaked or baked lasagna for up to 2 months. Thaw overnight in the fridge before baking or reheating.
Reheat: Warm in a 350°F oven, covered with foil, until heated through.

Cremini or baby bellas give the best texture and flavor, but any mix (shiitake, oyster, even portobello) will shine.
