Ingredients

(Tip: You can find the complete list of ingredients and their measurements in the recipe card below.)

Lasagna noodles – Choose classic or oven-ready noodles. They provide the perfect structure to hold the creamy layers together.

Fresh spinach – Adds a nutrient-packed green layer that balances out the rich cheese and sauce. You can also use frozen spinach (just make sure to squeeze out all the moisture).

Mushrooms – Cremini or button mushrooms work best, offering an earthy umami note that complements the creamy sauce.

Butter – Used as the base for the béchamel sauce, it gives the dish that silky texture and depth of flavor.

All-purpose flour – Helps thicken the sauce and gives it body. Stirring constantly ensures no lumps form.

Milk – The liquid foundation for the béchamel. Whole milk is ideal, but as I mentioned, almond milk or oat milk works wonderfully for a dairy-light version.

Garlic – Brings warmth and aroma to the spinach and mushroom mixture. Freshly minced garlic gives the best result.

Parmesan cheese – Adds a salty, nutty finish to the sauce, rounding out all the flavors perfectly.

Mozzarella cheese – Melts beautifully to give that signature cheesy stretch in every forkful.

Nutmeg – A pinch in the béchamel enhances its richness and complements the spinach beautifully.

Salt and black pepper – Simple seasonings that tie all the ingredients together, balancing the flavors.

Directions

Start by preheating your oven to 375°F (190°C). If you’re using regular lasagna noodles, cook them according to the package instructions, then drain and set aside.

In a large skillet, melt butter over medium heat. Add garlic and sauté until fragrant, then toss in sliced mushrooms. Cook until they release moisture and turn golden brown. Stir in the spinach and cook until just wilted. Set aside.

To make the béchamel sauce, melt butter in a saucepan, whisk in flour, and cook for about 2 minutes. Gradually add milk while whisking continuously until smooth and thickened. Stir in parmesan, nutmeg, salt, and pepper.

Assemble your lasagna in a baking dish by layering a thin layer of sauce, followed by noodles, the spinach-mushroom mixture, more sauce, and a sprinkle of mozzarella. Repeat the layers until all ingredients are used, finishing with sauce and cheese on top.

Bake uncovered for 35–40 minutes or until golden and bubbling. Allow it to rest for at least 10 minutes before slicing. This helps the layers set and makes serving much easier.
