Butternut Squash Puree: I like to use fresh roasted squash pureed until silky, which gives the filling a smooth, naturally sweet base.
Ricotta Cheese: Adds creaminess and a mild tang that balances the sweetness of the squash.
Milk: Helps loosen the butternut squash mixture into a spreadable consistency—feel free to add more for extra creaminess.
Nutmeg: Just a pinch elevates the butternut squash, enhancing its flavor without overpowering it.
Fresh or Cooked Spinach: Provides a verdant contrast and earthy flavor that wakes up the dish.
Mozzarella Cheese: Melts beautifully for that stretchy, gooey texture that makes lasagna so comforting.
Garlic: A little minced garlic adds a gentle kick and savory depth to the spinach layer.
Lasagna Noodles: You can use regular or gluten-free noodles; either one will work beautifully here.
Parmesan Cheese: Sprinkled on top for a nutty, salty finish and a golden crust.
Italian Seasoning, Paprika & Basil: These herbs and spices bring brightness and warmth that tie all the layers together.

Make It Your Way

One of my favorite things about this Butternut Squash Spinach Lasagna Recipe is how easy it is to personalize. Whether you want to make it vegan, gluten-free, or spice it up, this recipe adapts without losing its heart.

Gluten-Free Version: Swap out traditional noodles for brown rice or gluten-free lasagna noodles. I’ve done this often, and the texture is just as satisfying! Just be sure to check your noodle package for cook times.
Vegan Twist: Use vegan ricotta alternatives made from tofu and plant-based mozzarella. I tried this once for a friend, and nobody missed the dairy!
Seasonal Spin: In spring or summer, try using fresh baby spinach and a hint of lemon zest instead of garlic for a lighter flavor.
Extra Protein: Add some cooked lentils or crumbled tofu to the spinach filling for a protein boost without meat.

Step-by-Step: How I Make Butternut Squash Spinach Lasagna Recipe

Step 1: Roast and Puree Your Butternut Squash

I always start by roasting the butternut squash until it's tender and sweet—this usually takes about 40 minutes at 400°F. Once cooled, I puree it until silky smooth. This step is key to getting that luscious filling texture. Feel free to make extra puree; it keeps well for future recipes.

Step 2: Prepare the Butternut Squash Filling

In a bowl, combine your butternut squash puree with ricotta, milk, salt, and just a touch of nutmeg. I stir this well, tasting to adjust salt as needed. If the mixture feels too thick, add more milk gradually to make it spreadable but still creamy—this filling is the heart of the recipe, so getting this right makes all the difference.

Step 3: Cook and Prep the Spinach Filling

Cook your spinach until just wilted, then squeeze out excess water to avoid soggy layers. Mix it with ricotta, mozzarella, minced garlic, salt, and pepper. I sometimes toss in a splash of lemon juice to brighten it—a personal favorite touch. Again, tasting is key here; adjust seasoning so the spinach shines but isn’t overpowering.

Step 4: Cook the Lasagna Noodles

Boil your noodles according to package directions until al dente, then rinse in cold water. Trimming them to fit your baking dish neatly helps with a tidy assembly. If you’re short on time, you can use no-boil noodles—just add a bit of extra milk or stock to your squash filling to keep things moist during baking.

Step 5: Layering the Magic

Grease your baking dish lightly so nothing sticks. Spread a third of the squash mixture on the bottom, sprinkle mozzarella, then add noodles in a single layer without overlapping. Spread half the spinach filling, then more mozzarella, more noodles, another third of squash, sprinkling mozzarella again, noodles, rest of the spinach, mozzarella, noodles, and finish with the remaining squash filling. Top everything with mozzarella, parmesan, and a sprinkle of Italian seasoning, paprika, and basil.

Step 6: Bake and Enjoy

Cover with foil and bake at 375°F for 30 minutes, then remove the foil and bake another 10 minutes to get a golden cheesy top. Let it rest a few minutes before slicing—this helps it set and makes serving neater.

Top Tip

From my many batches, I've learned a few little tricks that really elevate the Butternut Squash Spinach Lasagna Recipe—these help you avoid soggy layers and keep every bite creamy yet firm.

Perfect Consistency: Don’t skip adding milk to the squash filling; it helps keep each layer luscious and prevents dryness.
Drain Your Spinach Well: Excess water from spinach can turn your lasagna watery—use a kitchen towel or cheesecloth to squeeze it dry.
Layer Smart: Trim noodles so they fit snugly and don’t overlap—this helps the lasagna bake evenly.
Let It Rest: After baking, give the lasagna at least 10 minutes to set; cutting too soon leads to runny layers.

How to Serve Butternut Squash Spinach Lasagna Recipe

butternut squash lasagna - Serving Suggestion

Garnishes

I love topping my lasagna slices with freshly chopped basil or parsley—it adds a fresh pop of color and a burst of herbal brightness. A drizzle of good quality olive oil or a sprinkle of chili flakes can also boost the flavor if you like a little heat.

Side Dishes

To balance the richness, I usually serve this dish with a crisp green salad dressed simply with lemon and olive oil. Roasted garlic bread or a light soup on the side also complement it perfectly for a well-rounded meal.

Creative Ways to Present

For special occasions, try assembling individual portions in small ramekins—people love the personalized touch and these mini servings make for charming presentations. You can also top each piece with little parmesan crisps or microgreens for added elegance.

Make Ahead and Storage

Storing Leftovers

I store leftovers covered tightly with foil or plastic wrap in the fridge for up to 4 days, though I swear my family never lets it last that long. To keep it from drying out, place the dish in a shallow container and cover snugly.

Freezing

This lasagna freezes beautifully. I usually freeze it before baking, wrapped tightly, then bake from frozen adding about 10-15 extra minutes. You can also freeze leftovers after baking—just make sure to cool completely before wrapping.

Reheating

Reheat in the oven at 350°F, covered with foil to prevent drying, until warmed through (about 20 minutes). Avoid microwaving if you want to keep that perfect texture, but if you’re in a hurry, microwave in short bursts and stir gently to distribute heat.

Frequently Asked Questions:

Can I use frozen spinach instead of fresh?

Absolutely! Thaw and squeeze out all excess water from frozen spinach before using it in the filling to avoid sogginess. Fresh spinach is lovely, but frozen works well for convenience.

Can I prepare this lasagna vegan-friendly?

Yes! Swap regular cheeses for vegan ricotta and mozzarella alternatives—which can be store-bought or homemade using tofu and nutritional yeast. I’ve tried this substitution, and it’s delicious without losing that creamy texture.

What’s the best way to prevent watery lasagna?

Drain spinach thoroughly to remove excess moisture, don’t overcook the noodles, and avoid overlapping noodles in the layers. Also, adding milk to the butternut squash mixture ensures creamy but not watery filling.

Can I make this dish ahead of time?

Yes! This dish is great for meal prep. Assemble it a day ahead, store covered in the fridge, and bake it fresh. It also freezes wonderfully, either pre- or post-baking. Just remember to adjust baking time if baking from frozen.

Final Thoughts

This Butternut Squash Spinach Lasagna Recipe is one of those dishes I come back to again and again when I want comfort food without feeling heavy.
