How to Make Savory Pumpkin & Spinach Lasagna

1. Prepare the Pumpkin Filling

Heat the olive oil in a skillet over medium heat.

Add the chopped onion and cook for about 4–5 minutes, until softened and lightly golden.

Add the minced garlic and cook for another 30 seconds.

Stir in the pumpkin purée, sage, thyme, nutmeg, salt, and black pepper.

Pour in the broth and heavy cream. Stir everything together and simmer gently for about 5 minutes.

The mixture should be creamy but not watery.

Remove from the heat and set aside.

2. Prepare the Spinach

Heat a tablespoon of olive oil in a large skillet.

Add the spinach and cook until wilted, about 2–3 minutes.

Add the garlic, salt, and black pepper and cook for another 30 seconds.

Remove from the heat and allow the spinach to cool slightly.

If the spinach releases a lot of liquid, squeeze or drain it well. Excess moisture can make the lasagna watery.

3. Make the Spinach-Cheese Filling

Place the cooked spinach in a bowl.

Add the ricotta, feta, egg, and Parmesan.

Mix until evenly combined.

Taste and adjust the seasoning if necessary. Keep in mind that feta and Parmesan are already salty.

4. Cook the Lasagna Noodles

Cook the lasagna noodles according to the package directions until just tender.

Drain them and lay them flat on a lightly oiled baking sheet or parchment paper so they don’t stick together.

If you’re using oven-ready noodles, you can skip this step and follow the package instructions.

5. Assemble the Lasagna

Preheat your oven to 375°F (190°C).

Lightly grease a 9×13-inch baking dish.

Spread a thin layer of pumpkin sauce over the bottom.

Add a layer of lasagna noodles.

Spread part of the spinach-ricotta mixture over the noodles.

Sprinkle with mozzarella and a little feta.

Repeat the layers:

Pumpkin mixture → noodles → spinach mixture → cheese

Continue until everything has been used.

Finish with a final layer of noodles topped with pumpkin sauce.

Sprinkle the remaining mozzarella, Parmesan, and feta over the top.

For an especially beautiful finish, add a few fresh sage leaves.

6. Bake Until Golden and Bubbly

Cover the baking dish loosely with aluminum foil.

Bake for 25–30 minutes.

Remove the foil and continue baking for another 10–15 minutes, until the cheese is melted, bubbling, and lightly golden.

For a more deeply browned top, you can broil it briefly at the end, watching carefully so the cheese doesn’t burn.

Let the lasagna rest for 10–15 minutes before slicing.

This gives the layers time to settle and makes the lasagna much easier to serve.

Make the Brown Butter Sage Drizzle

While the lasagna is resting, prepare the finishing drizzle.

Place the butter in a small saucepan over medium heat.

Once melted, add the fresh sage leaves.

The butter will begin to foam. Continue cooking while swirling the pan occasionally.

After several minutes, you’ll notice small golden-brown specks forming at the bottom and a delicious nutty aroma developing.

Add the minced garlic during the final 30 seconds of cooking.

Remove from the heat and add a tiny pinch of salt.

If desired, stir in a teaspoon of lemon juice to brighten the richness.

Finish the Lasagna

Cut the rested lasagna into squares.

Drizzle a little brown butter and sage over each serving.

Finish with extra Parmesan, crumbled feta, and a few crispy sage leaves.

The combination of creamy pumpkin, earthy spinach, salty feta, and nutty brown butter is incredibly satisfying.

Tips for the Best Pumpkin Lasagna

Use Pure Pumpkin Purée

Make sure you’re using plain pumpkin purée rather than sweetened pumpkin pie filling. Pie filling contains sugar and spices that aren’t suitable for this savory dish.

Drain the Spinach Well

This is one of the most important steps.

Spinach naturally releases water as it cooks. Too much moisture can make your lasagna loose and watery.

Don’t Overdo the Nutmeg

A small amount of nutmeg adds warmth to pumpkin and creamy sauces, but too much can overpower the other flavors.

Let the Lasagna Rest

Don’t cut into the lasagna immediately after removing it from the oven.

Give it at least 10 minutes to rest so the layers can firm up.

Watch the Brown Butter

Brown butter can go from perfectly golden to burnt very quickly.

As soon as you see golden-brown milk solids and smell a nutty aroma, remove it from the heat.

Delicious Variations

Add Mushrooms

Sauté sliced mushrooms with the spinach for an earthy, hearty version.

Use Butternut Squash

Roasted butternut squash can replace some or all of the pumpkin.

Add Caramelized Onions

Slowly caramelized onions bring natural sweetness that works beautifully with pumpkin and sage.

Make It Extra Cheesy

Add shredded Gruyère, fontina, or additional mozzarella between the layers.

Add Walnuts

A small handful of toasted chopped walnuts adds wonderful crunch and pairs particularly well with brown butter and sage.

Add Red Pepper Flakes

For a little heat, add ¼–½ teaspoon red pepper flakes to the pumpkin mixture.

What to Serve With Pumpkin Lasagna

Because this lasagna is rich and creamy, simple sides work especially well.

Try serving it with:

Crisp green salad
Arugula with lemon vinaigrette
Roasted Brussels sprouts
Steamed green beans
Garlic bread
Crusty sourdough
Roasted vegetables

A bright salad with lemon-based dressing is particularly good because the acidity balances the richness of the cheese and brown butter.

Make-Ahead Instructions

This lasagna is an excellent make-ahead meal.

Assemble it completely, cover tightly, and refrigerate for up to 24 hours before baking.

When ready to cook, allow the dish to sit at room temperature briefly while the oven preheats.

You may need to add a few extra minutes to the baking time if the lasagna is thoroughly chilled.

For the best texture, prepare the brown butter sage drizzle shortly before serving.

Storage

Store leftover lasagna in an airtight container in the refrigerator for up to 3–4 days.

Reheat individual portions in the microwave or place them in a covered baking dish and warm them in a 350°F (175°C) oven until heated through.

The lasagna can also be frozen.

Wrap individual portions well and freeze for up to about 2–3 months for best quality.

Thaw overnight in the refrigerator before reheating.

Frequently Asked Questions

Can I use frozen spinach?

Yes. Frozen spinach works very well. Thaw it completely and squeeze out as much excess liquid as possible before adding it to the ricotta mixture.

Can I use canned pumpkin?

Yes. Plain canned pumpkin purée is convenient and works beautifully in this recipe.

Can I make this without feta?

Absolutely. Ricotta, Parmesan, mozzarella, and Gruyère can all be used to create slightly different versions.

Can I make it vegetarian?

Yes. Use vegetable broth rather than chicken broth.

Can I prepare the brown butter ahead of time?

Yes. You can prepare it several hours ahead and gently warm it before serving. However, freshly made brown butter has the best aroma and flavor.

Why is my lasagna watery?

The most common reasons are excess moisture from spinach, watery pumpkin purée, or cutting the lasagna before it has rested. Drain the spinach thoroughly and allow the finished lasagna to rest before slicing.
