9 lasagna noodles: Choose regular noodles that will cook up tender but sturdy for layering.
1 15-ounce package whole milk ricotta: Whole milk ricotta ensures a creamy, smooth texture.
2 10-ounce packages frozen chopped spinach, thawed and drained: Properly drained spinach prevents excess moisture in the lasagna.
3 cups shredded mozzarella cheese, divided: Mozzarella melts beautifully, creating that gooey, cheesy stretch we all love.
¾ cup freshly grated Parmesan, divided: Parmesan adds a punch of nutty, savory flavor.
2 tablespoons chopped fresh parsley leaves: Fresh parsley tops off the dish with a pop of green and freshness.
¼ cup unsalted butter: Butter forms the base of the luscious mushroom sauce.
2 cloves garlic, minced: Garlic adds a warm, aromatic foundation.
1 pound cremini mushrooms, thinly sliced: These mushrooms offer an earthy, meaty bite.
1 onion, diced: Onion brings sweetness and depth when sautéed.
¼ cup all-purpose flour: Flour thickens the rich sauce to the perfect consistency.
3 cups milk, at room temperature: Milk creates the creamy base of the sauce without overpowering other flavors.
1 teaspoon dried basil: Basil infuses herby warmth that complements the vegetables.
½ teaspoon dried oregano: Adds a hint of classic Italian flavor.
Pinch of nutmeg: Nutmeg surprises with a subtle, comforting spice in the sauce.
Kosher salt and freshly ground black pepper, to taste: Essential seasonings to balance and highlight every flavor.

How to Make Creamy Spinach and Mushroom Lasagna Recipe

Step 1: Prepare the Mushroom Sauce

Start by melting the butter in a saucepan over medium heat, then add minced garlic, sliced mushrooms, and diced onion. Cook these together until everything is tender and wonderfully fragrant—around 3 to 4 minutes. Next, sprinkle in the flour and stir it in well, cooking for about a minute until it’s lightly browned. This step is key as it will thicken the sauce and create that beautiful velvety texture.

Step 2: Add the Milk and Seasonings

Slowly whisk in the room temperature milk, ensuring no lumps form. Keep whisking for 2 to 3 minutes until the sauce begins to thicken up nicely. Now, stir in dried basil, oregano, and the pinch of nutmeg—these herbs will awaken the flavors and complement the mushrooms and spinach perfectly. Season with kosher salt and freshly cracked black pepper to your taste, then set the sauce aside. It’s already smelling incredible!

Step 3: Cook the Lasagna Noodles

While the sauce cools slightly, bring a large pot of salted water to a boil and cook the lasagna noodles according to the package instructions. Once cooked, drain and lay them flat to prevent sticking. The noodles will create the sturdy yet tender layers that hold all those creamy fillings together so beautifully.

Step 4: Assemble Your Lasagna

Grab a 9×13-inch baking dish and spread 1 cup of the mushroom sauce evenly on the bottom. Layer on 3 lasagna noodles, then half of the ricotta, followed by half of the drained spinach, 1 cup of mozzarella, and a quarter cup of Parmesan cheese. Repeat this layering process once more for a rich, double-layered structure. After that, top with the remaining noodles, mushroom sauce, and cheeses. This final layer seals in all the gooey goodness.

Step 5: Bake to Perfection

Pop the assembled lasagna into a preheated 350°F oven and let bake for 35 to 45 minutes until it’s bubbling happily and heated through. For that irresistible golden, slightly crispy top, switch the oven to broil for the last 2 to 3 minutes. Keep an eye on it—it goes from beautifully browned to burnt quickly! After removing, let it rest for about 15 minutes to set up for perfect slicing.

Garnishes

Finishing your lasagna with freshly chopped parsley really brightens the plate and adds a refreshing herbaceous note that cuts through the richness. A light sprinkle of extra Parmesan at the table invites those who want a cheesier experience.

Side Dishes

This dish pairs wonderfully with crisp, simple sides like a fresh green salad dressed with lemon vinaigrette or roasted seasonal vegetables. They add a pleasant crunch and freshness to each satisfying, creamy bite of lasagna. Garlic bread is also a classic companion, perfect for sopping up any leftover sauce.

Creative Ways to Present

For a special occasion, serve the lasagna in individual ramekins or smaller portions. Garnish each one with a sprig of parsley and a drizzle of high-quality olive oil. Another idea is layering the ingredients in a glass casserole dish for a beautiful visual effect where you can see each luscious layer.

Make Ahead and Storage

Storing Leftovers

Your Creamy Spinach and Mushroom Lasagna Recipe keeps beautifully in the refrigerator, tightly covered, for up to 3 to 4 days. The flavors meld and deepen overnight, so leftovers often taste even better than when freshly made.

Freezing

This lasagna shines as a freezer-friendly meal. After assembling and before baking, cover it tightly with foil and freeze for up to 3 months. When you’re ready, simply thaw in the refrigerator overnight and bake as directed. It’s the perfect stress-free dinner option for busy weeks.

Reheating

Reheat individual slices in the microwave for about 2 minutes or until heated through, or warm a larger portion in a 350°F oven covered with foil to prevent drying out. If frozen, make sure to thaw completely for even heating and best texture.

FAQs

Can I use fresh spinach instead of frozen in this Recipe?

Absolutely! If you prefer fresh spinach, sauté about 10 ounces until wilted, drain any excess liquid, and use as directed. Frozen spinach is just convenient and helps avoid extra moisture.

Is this lasagna recipe suitable for vegetarians?

Yes, this Creamy Spinach and Mushroom Lasagna Recipe is completely vegetarian-friendly, as it contains no meat or meat-based broths—just hearty vegetables, cheese, and herbs.

How can I make this dish gluten free?

You can swap out regular lasagna noodles for gluten-free varieties. Just make sure to follow the cooking instructions on the package since gluten-free noodles can vary in texture and cook time.

What wine pairs well with this lasagna?

A medium-bodied white wine like Chardonnay or a light red such as Pinot Noir complement the creamy, earthy flavors nicely. The key is to balance intensity without overpowering the dish.
