Ingredients You’ll Need

For the Cooked Spinach

Olive oil: Helps sauté the vegetables and adds a subtle richness.

Onion: Chopped white or yellow onion creates a savory base for the spinach.

Garlic: Fresh minced garlic adds plenty of flavor to the greens.

Fresh spinach: Spinach wilts down and becomes tender, savory, and easy to layer into the ricotta filling.

Salt and black pepper: Season the spinach and bring out its natural flavor.

For the Pumpkin Filling

Pumpkin puree: Use plain canned pumpkin puree, not pumpkin pie filling. It creates the creamy, slightly sweet base for the lasagna.

Unsweetened milk: Almond milk or another milk of your choice helps turn the pumpkin into a smooth, spoonable sauce.

Ground cinnamon: Adds gentle warmth that pairs beautifully with pumpkin.

Ground nutmeg: Gives the pumpkin layer a classic cozy flavor.

Kosher salt: Balances the sweetness of the pumpkin and enhances the other flavors.

For the Ricotta Filling

Ricotta cheese: Creates a creamy, rich filling with a light texture. Part-skim or full-fat ricotta both work.

Egg: Helps bind the ricotta mixture together as the lasagna bakes.

Shredded mozzarella: Adds extra creaminess and that delicious melted-cheese texture.

Parmesan cheese: Brings salty, savory depth to the ricotta filling.

Dried oregano or basil: Adds an herby flavor that complements the spinach and cheese.

Salt and black pepper: Season the creamy filling.

For Layering

No-boil lasagna noodles: These make this easy pumpkin lasagna especially convenient.

Shredded mozzarella: Melts over the layers for a gooey, cheesy finish.

Grated Parmesan: Adds a savory golden topping as the lasagna bakes.

Fresh basil or parsley: A sprinkle of fresh herbs brightens the finished dish.

How to Make Vegetarian Pumpkin Spinach Lasagna

Step 1: Cook the Spinach

Start by heating the olive oil in a large skillet or non-stick pan over medium heat.

Add the chopped onion and season with salt and pepper. Cook for about 2–3 minutes, stirring occasionally, until the onion begins to soften.

Add the minced garlic and cook for another minute, just until fragrant.

Add the fresh spinach to the skillet. It may look like a lot at first, but don’t worry—it will quickly wilt down.

Toss the spinach with the onion and garlic so it becomes coated in all those savory flavors. Cook for about 3–4 minutes, until the spinach is completely wilted.

Taste and adjust the seasoning if needed. Remove from the heat and allow the spinach mixture to cool slightly.

Step 2: Prepare the Pumpkin Filling

While the spinach cooks, prepare the pumpkin layer.

Add the pumpkin puree, unsweetened milk, cinnamon, nutmeg, and kosher salt to a medium mixing bowl.

Stir until everything is well combined and the pumpkin mixture is smooth and creamy.

Be sure to use pure pumpkin puree rather than pumpkin pie filling, since pie filling contains added sugar and spices.

Step 3: Make the Ricotta Filling

In another medium mixing bowl, combine the ricotta cheese, egg, shredded mozzarella, Parmesan, oregano or basil, salt, and black pepper.

Stir until the mixture is creamy and evenly combined.

Once the cooked spinach has cooled enough to handle, fold it into the ricotta mixture.

This creates a flavorful spinach ricotta filling that will spread beautifully between the lasagna noodles.

Step 4: Assemble the Lasagna

Preheat your oven to 400°F and lightly spray a 9×13-inch baking dish or lasagna pan with cooking spray.

Begin by spreading about ½ cup of the pumpkin mixture over the bottom of the prepared pan.

Arrange 5 lasagna noodles over the pumpkin layer.

Spread half of the spinach ricotta filling over the noodles. Add some of the mozzarella, followed by more pumpkin filling and Parmesan.

Repeat the layers with the remaining noodles, ricotta spinach mixture, pumpkin filling, mozzarella, and Parmesan.

Try to spread the fillings as evenly as possible so every serving has a good balance of pumpkin, spinach, noodles, and cheese.

Step 5: Bake

Cover the baking dish tightly with foil and place it on the center rack of the preheated oven.

Bake for 25 minutes.

Remove the foil and continue baking for another 15–20 minutes, until the cheese is melted and the lasagna is hot and bubbling.

For an especially golden top, you can keep an eye on the cheese during the final few minutes of baking.

Step 6: Rest and Serve

Remove the lasagna from the oven and let it rest for at least 25 minutes before slicing.

This resting time is important because it allows the creamy layers to settle, making the lasagna much easier to cut and serve.

Finish with freshly chopped basil or parsley before serving.

Tips for Success

Use pure pumpkin puree. Avoid pumpkin pie filling, which contains sugar and added spices that can make the lasagna overly sweet.

Don’t skip the resting time. Letting the lasagna cool for at least 25 minutes helps the layers set and makes cleaner slices.

Season each component. The spinach, pumpkin mixture, and ricotta filling should each be properly seasoned so the finished lasagna doesn’t taste bland.

Let the spinach cool slightly. Adding very hot spinach directly to the ricotta mixture can make the filling looser than you want.

Use no-boil noodles for convenience. They make this recipe much easier to assemble. If using regular lasagna noodles, cook them according to the package directions before layering.

Watch the moisture. If using frozen spinach, thaw it completely and squeeze out as much excess liquid as possible before sautéing.

Equipment Needed

• 9×13-inch baking dish or lasagna pan

Recipe Variations

Pumpkin Kale Lasagna

Swap the spinach for kale for a slightly heartier version. Remove the tough stems, chop the kale finely, and sauté it until tender before mixing it into the ricotta filling.

Vegan Pumpkin Lasagna

Make this pumpkin lasagna completely dairy-free by using plant-based ricotta, mozzarella, and Parmesan. Choose vegan lasagna noodles as well.

Pumpkin Butternut Squash Lasagna

Replace the pumpkin puree with mashed or pureed butternut squash. The squash provides a similar creamy texture with a naturally sweet, earthy flavor.

Sweet Potato Spinach Lasagna

Mashed or canned sweet potato can also replace the pumpkin. It creates a slightly sweeter filling while keeping the cozy flavor profile of the original recipe.

Pumpkin Lasagna With Sausage

For a non-vegetarian variation, add cooked crumbled sausage to the ricotta and spinach mixture or layer it separately between the noodles.

Pumpkin Lasagna With Ground Turkey

Cooked ground turkey can be mixed into the ricotta filling for extra protein and a heartier dinner.

Gluten-Free Pumpkin Lasagna

Use your favorite gluten-free lasagna noodles. No-boil gluten-free noodles can make the recipe especially convenient.

What to Serve With Pumpkin Spinach Lasagna

This vegetarian lasagna is hearty enough to be the centerpiece of a meal, but a few simple sides make it even better.

Serve it with a crisp green salad tossed with a light lemon vinaigrette for freshness. Roasted vegetables such as broccoli, Brussels sprouts, or carrots also pair nicely with the creamy lasagna.

For a cozy Italian-inspired dinner, add warm garlic bread or crusty bread on the side.

A simple tomato salad can also provide a refreshing contrast to the rich pumpkin and cheese layers.

Frequently Asked Questions

Can I use frozen spinach?

Yes. Thaw the frozen spinach completely and squeeze out as much excess liquid as possible. Then sauté it with the onion and garlic before adding it to the ricotta mixture.

Can I make pumpkin lasagna ahead of time?

Yes. You can assemble the lasagna ahead of time and keep it covered in the refrigerator until you’re ready to bake. If it is very cold when it goes into the oven, it may need a little additional baking time.

Can I use regular lasagna noodles?

Absolutely. If you use traditional lasagna noodles, cook them according to the package instructions before assembling the lasagna. Rinse them after cooking and lay them on a lightly sprayed baking sheet while you prepare the remaining ingredients.

Can I make this lasagna vegan?

Yes. Replace the ricotta, mozzarella, and Parmesan with dairy-free alternatives and use vegan lasagna noodles. For lentil lasagna noodles, cook them according to the package directions before assembling.

How long does pumpkin spinach lasagna last in the refrigerator?

Store the cooked lasagna covered in the refrigerator for up to 5 days. The flavors often become even better after a day or two, making this a great meal-prep recipe.

Can I use something other than pumpkin?

Yes. Mashed sweet potato or butternut squash are excellent alternatives. Pumpkin gives the most distinctive seasonal flavor, but both substitutions work well.
