- 2 tablespoons olive oil
- 1 medium yellow onion, finely chopped
- 1 pound cremini or white mushrooms, sliced
- 4 garlic cloves, minced
- 1 teaspoon salt
- 1 teaspoon black pepper
- 10 ounces fresh baby spinach
- 2 tablespoons butter
- 2 tablespoons all-purpose flour
- 2 cups whole milk
- ¼ teaspoon ground nutmeg
- 1 cup ricotta cheese
- 2 cups shredded mozzarella cheese

This ingredient list balances rich dairy, earthy mushrooms, and fresh greens, delivering an irresistible lasagna that’s both satisfying and wholesome.
Step-by-Step Guide to Making Spinach and Mushroom Lasagna
Begin by heating olive oil in a large skillet over medium heat. Add the chopped onion and sauté until translucent, about 5 minutes. Then stir in the sliced mushrooms and cook until they release their moisture and become golden brown, around 10–12 minutes. Add minced garlic, salt, and pepper and cook for an additional minute until fragrant. Once the mushrooms are cooked, add the fresh spinach in batches, stirring until wilted. Set the vegetable mixture aside.
Next, prepare the béchamel sauce by melting butter in a saucepan over medium heat. Whisk in the flour to form a smooth roux, cooking for 1–2 minutes until it slightly darkens. Slowly pour in the milk while whisking constantly to prevent lumps. Cook the sauce until it thickens and coats the back of a spoon, about 6–8 minutes. Stir in the nutmeg, then remove from heat.
Now it’s time to assemble the lasagna. Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish. Spread a small amount of béchamel sauce on the bottom of the dish, followed by a layer of noodles. Add a layer of the spinach and mushroom mixture, a few dollops of ricotta, and a generous sprinkle of mozzarella. Repeat the layers—béchamel, noodles, vegetables, ricotta, and cheese—until all ingredients are used up, finishing with a layer of béchamel and a topping of mozzarella and Parmesan cheese.
Cover the lasagna with foil and bake for 25–30 minutes. Remove the foil and bake for an additional 10–15 minutes, or until the top is golden and bubbling. Let it rest for at least 10 minutes before slicing and serving. This allows the layers to set beautifully.
Expert Tips for a Perfect Spinach and Mushroom Lasagna
To elevate your lasagna game, keep these expert tips in mind:
- Use no-boil lasagna noodles to save time, but make sure there’s enough moisture in your sauce to soften them properly.
- For extra creaminess, mix a bit of ricotta into the béchamel before layering.
- Always sauté the mushrooms long enough for them to caramelize and develop deep flavor.
- Layer evenly to ensure each bite includes a perfect balance of filling, sauce, and cheese.
- Let the lasagna rest before slicing to help it hold its shape and avoid a soupy serving.
Common Mistakes to Avoid When Making Spinach and Mushroom Lasagna
Even the best recipes can go wrong if you’re not careful. Avoid these common pitfalls:
- Skipping the sauté: Raw mushrooms and spinach will release water and make the lasagna soggy.
- Not thickening the béchamel enough: A runny sauce can ruin the texture of the dish.
- Overstuffing the layers: Too much filling makes it hard for the lasagna to hold together.
- Forgetting to cover with foil: This can cause the cheese to burn before the inside is cooked.
- Cutting too soon: Without a resting period, the layers won’t stay intact when sliced.
Tasty Variations and Swaps for Spinach and Mushroom Lasagna
Want to make this recipe your own? Try one of these delicious variations:
- Add thinly sliced zucchini or roasted red peppers for more veggie variety.
- Use kale or Swiss chard instead of spinach if you prefer a different green.
- Swap out ricotta for cottage cheese for a lighter, protein-rich alternative.
- Use a gluten-free flour blend and noodles to make this dish gluten-free.
- Add a layer of marinara sauce between noodles and vegetables for a hybrid red-white lasagna.
These substitutions and additions are easy to incorporate while keeping the heart of the recipe intact.
Serving and Presentation Ideas for Spinach and Mushroom Lasagna
To make your lasagna as eye-catching as it is tasty, try these serving ideas:
- Sprinkle fresh chopped parsley or basil on top just before serving for a touch of color.
- Serve each slice on a wide plate with a light drizzle of olive oil or a spoon of extra béchamel.
- Pair with a green salad dressed in lemon vinaigrette for balance.
- Offer a bowl of roasted vegetables or garlic bread as hearty side dishes.
Presentation doesn’t have to be complicated—a few thoughtful touches make a big difference.
How to Store and Reheat Leftover Spinach and Mushroom Lasagna
One of the best things about lasagna is how well it stores. Here’s how to keep leftovers fresh:
- Refrigerate leftovers in an airtight container for up to 4 days.
- For longer storage, freeze individual portions tightly wrapped in foil or in freezer-safe containers for up to 2 months.
- To reheat, place a slice in a baking dish covered with foil and bake at 350°F (175°C) for 20–25 minutes. Alternatively, microwave on medium power in 1-minute intervals until heated through.
Proper storage not only preserves the flavor but makes for an easy weekday meal.
What to Serve with Spinach and Mushroom Lasagna

- A fresh arugula or mixed greens salad
- Roasted vegetables like carrots, asparagus, or Brussels sprouts
- A warm side of garlic or herb focaccia bread
- A simple bowl of tomato basil soup
- Steamed green beans with a squeeze of lemon
These pairings keep your meal balanced and satisfying without overwhelming the rich main dish.
