Cheesy, leafy spinach lasagna flavored with a hint of nutmeg. Layers of lasagna sheets are filled with three cheeses and a silky white béchamel, then baked until golden for a rich vegetarian lasagna.
This spinach lasagna is a staple for any cook looking for a satisfying vegetarian main. Fresh spinach becomes a flavorful, creamy filling tucked between pasta sheets and layered with ricotta, mozzarella and parmesan. The béchamel adds silkiness and a bit of nutmeg ties the flavors together for a comforting, cheesy bite every time.
Why this spinach lasagna recipe works
This version follows the structure of a traditional lasagna al forno but replaces meat with a rich spinach-cheese filling. It delivers restaurant-quality flavor because:
- Key components are made from scratch — a smooth white béchamel and a seasoned spinach mixture.
- Three cheeses (mozzarella, ricotta, parmesan) provide creaminess, structure and savory depth.
- The spinach filling is aromatic, seasoned with onion, garlic, Italian herbs and nutmeg for warmth.
History
Lasagna has roots in medieval Italy and now appears in many regional variations worldwide. The lasagna al forno, often associated with the Bologna region, features layered pasta sheets with rich sauces and cheese. Other notable regional versions come from Naples and southern Italy.
Spinach filling
Spinach is an excellent vegetarian lasagna filling: it cooks down to a soft, flavorful texture and pairs beautifully with cheeses. Onions and garlic build the base flavor while ricotta and eggs add body and binding. A pinch of nutmeg brightens the overall profile.
Béchamel sauce
Béchamel is a classic white sauce made from a roux (butter and flour) and milk or cream. For this recipe, half-and-half (equal parts milk and cream) gives a creamy consistency while chicken stock enriches the flavor. The sauce is seasoned simply with garlic, salt, pepper and a touch of nutmeg, then finished with mozzarella for extra creaminess.

How to make spinach lasagna
This summary shows the steps: cook the lasagna sheets, prepare the béchamel, make the spinach filling, then layer and bake.
- Make the béchamel sauce.
- Prepare the spinach-ricotta filling.
- Layer the lasagna and bake.
Cook lasagna sheets
Bring a large pot of salted water to a boil and cook the lasagna sheets until al dente, following the package directions. Slight undercooking is fine since they will finish cooking in the oven. Preheat the oven to 425°F (220°C).
Make the white sauce
Melt butter with a splash of olive oil in a saucepan. Sauté minced garlic briefly until fragrant. Stir in flour and cook on low for about a minute, keeping the roux pale. Gradually whisk in chicken broth, then half-and-half, until smooth and lump-free. Remove from heat, season with salt and pepper, and stir in about 1 cup of shredded mozzarella for a thicker, cheesy sauce.
Make the spinach filling
If using fresh spinach: blanch in boiling water for 1 minute, then transfer to ice water, drain, chop and squeeze out excess moisture. If using frozen spinach: thaw and squeeze dry.
Sauté chopped onion and garlic in olive oil until soft. Add the drained spinach and cook briefly until any remaining moisture evaporates. Let cool.
In a large bowl, combine the cooked spinach mixture with drained ricotta, shredded mozzarella, grated parmesan, eggs, Italian seasoning, nutmeg, salt and pepper. Mix until well combined.
How to layer the lasagna
Spread a couple tablespoons of béchamel in the bottom of a 9×13-inch baking dish. Arrange three lasagna sheets to cover the base. Spread about 1/2 cup of the spinach mixture over the sheets, then spoon 1/3 cup of béchamel on top.
Repeat with three more sheets and the fillings two more times, ending with a top layer of lasagna sheets. Spread remaining béchamel over the top. Insert 6–7 toothpicks vertically across the surface so foil won’t touch the sauce, then loosely cover with foil.
Bake the lasagna
Bake covered for 30 minutes. Remove foil and toothpicks, sprinkle 1 cup of mozzarella over the top, and return to the oven for 10–12 minutes until cheese is bubbly and lightly browned. Let rest for about 10 minutes, garnish with parsley, then cut into slices and serve.
Store lasagna
Refrigerate leftover lasagna for up to 5 days. For longer storage, freeze wrapped tightly in foil or placed in an airtight container for up to 3 months to avoid freezer burn.
To reheat from frozen, preheat the oven to 425°F (220°C). Add a little water or sauce to the top to keep it moist and bake for about 45 minutes. Reheat refrigerated portions in the oven for 15 minutes or microwave until warm.
Serve with
Lasagna is satisfying on its own but pairs well with garlic bread, a simple tossed salad or roasted vegetables to balance the richness. Light, fiber-rich salads or roasted root vegetables complement the dish nicely.
Other Italian recipes
For variety, consider other baked pasta or Italian-inspired dishes that pair well with this lasagna theme—creamy dressings, hearty soups, or roasted chicken and potato bakes offer complementary flavors and textures.
