Spinach Lasagna Recipe

Spinach lasagna has always been one of those reliable meals I turn to when I need something hearty that will feed a group without much stress.

It feels comforting and familiar, and it works just as well for a casual family dinner as it does for a gathering with friends. I especially love that it gives you all the satisfaction of classic lasagna while being packed with greens.

This version layers tender noodles with sautéed spinach, creamy ricotta filling, marinara sauce, and plenty of mozzarella and Parmesan.

It bakes into a bubbling, cheesy dish that slices beautifully after a short rest. And if you are lucky enough to have leftovers, it tastes even better the next day.

I started making spinach lasagna when I wanted a vegetarian main dish that still felt complete. Meatless recipes can sometimes feel like they are missing something, but with three cheeses and well-seasoned spinach, this one never does. Over time, I learned that squeezing the spinach dry and letting the lasagna rest before slicing makes all the difference.

Now it is one of my go-to recipes when I need something dependable and filling.

Ingredients in This Recipe

For the Filling

1. 1 tablespoon butter: Used to sauté the spinach and enhance flavor.
2. 24 ounces fresh spinach leaves: Wilted down to create a rich green layer.
3. 15 ounces ricotta cheese: Provides creamy texture and mild flavor.
4. 2 eggs: Help bind the filling together.
5. ¾ cup grated Parmesan cheese: Adds sharp, savory depth.
6. 1 cup shredded mozzarella cheese: Mixed into the filling for creaminess.
7. ½ teaspoon salt (plus more if needed): Balances flavors.
8. ¼ teaspoon pepper (plus more if needed): Adds gentle warmth.
9. ½ teaspoon Italian seasoning: Brings classic herb flavor.

For Assembly

1. 1 box lasagna noodles: Cooked according to package directions.
2. 24-ounce jar marinara sauce: Provides moisture and rich tomato flavor.
3. 2 cups shredded mozzarella cheese: Sprinkled on top for a melted finish.
4. Cooking spray: Prevents sticking.
5. 2 tablespoons chopped parsley: Adds freshness and color at the end.

Ingredient Substitutions

Ingredient Spotlight

• Spinach: Fresh spinach cooks down significantly, creating a concentrated flavor while adding nutrients and color. Properly draining it ensures a firm, sliceable lasagna.

• Ricotta Cheese: This soft Italian cheese creates a creamy, rich layer that balances the acidity of the marinara sauce.

Instructions for Making This Recipe

Assemble the Lasagna

6. Preheat the oven to 375°F. Spray a 9×13 baking pan with cooking spray.
7. Spread a thin layer of marinara sauce on the bottom of the pan.
8. Add a layer of noodles, followed by one-third of the cheese and spinach mixture.
9. Spoon one-third of the marinara sauce over the filling.
10. Repeat the layers two more times, finishing with marinara sauce on top.
11. Cover with aluminum foil and bake for 45 minutes.
12. Remove foil, sprinkle 2 cups shredded mozzarella cheese evenly on top, and bake for an additional 15 minutes until melted and lightly golden.
13. Sprinkle with 2 tablespoons chopped parsley. Let rest for 5 to 10 minutes before slicing and serving.
