Step-by-Step Guide
How to Make Butternut Squash Lasagna
- Preheat the Oven and Prepare the Squash:
Start by preheating your oven to 400°F (200°C). Peel and cube the butternut squash. Spread the cubes on a baking sheet, drizzle with olive oil, and season with a pinch of salt and pepper. Roast the squash in the oven for 25-30 minutes or until soft and lightly caramelized. Once roasted, mash the squash with a fork or blend it in a food processor until smooth.
- Make the Béchamel Sauce:
In a medium saucepan, melt 2 tablespoons butter over medium heat. Add 2 tablespoons flour and whisk continuously to form a roux. Gradually add 2 cups milk, whisking until the sauce thickens. Season with salt, pepper, and a pinch of nutmeg. Stir in 1 teaspoon fresh sage for a fragrant, herbal note. Set aside.
- Prepare the Lasagna Noodles and Spinach:
While the squash is roasting, cook your lasagna noodles according to package instructions (or use no-boil noodles for convenience). Drain and set aside. In a separate pan, sauté the spinach in 1 tablespoon olive oil until wilted. Add the minced garlic during the last minute of cooking, and season with a little salt and pepper.
- Assemble the Lasagna:
In a 9×13-inch baking dish, spread a thin layer of béchamel sauce on the bottom. Place a layer of lasagna noodles over the sauce. Spread half of the roasted butternut squash mixture over the noodles, followed by half of the sautéed spinach. Add a few dollops of ricotta cheese (if using), then sprinkle with mozzarella and Parmesan cheese. Repeat the layers, finishing with a final layer of béchamel sauce, mozzarella, and Parmesan on top.
- Bake the Lasagna:
Cover the lasagna with aluminum foil and bake at 375°F (190°C) for 30 minutes. Remove the foil and bake for another 15-20 minutes, or until the top is golden and bubbly. Let the lasagna rest for about 10 minutes before slicing to allow the layers to set.
Butternut Squash Lasagna Variations
1. Add Protein:
For a heartier meal, consider adding cooked chicken or turkey to the layers. Ground sausage or even a mixture of beans can also add protein without sacrificing flavor.
2. Use Sweet Potatoes:
If you’re craving a slightly different taste, swap out the butternut squash for roasted sweet potatoes. This variation will give your lasagna a slightly different sweetness and texture but still complement the other ingredients perfectly.
3. Spice It Up:
If you like a little heat, add a sprinkle of red pepper flakes to the sauce or mix in a dash of cayenne pepper. You can also try using spicy sausage or chili flakes in the squash filling for an extra kick.
4. Vegan Butternut Squash Lasagna:
To make this dish vegan, simply swap out the cheese for dairy-free alternatives like vegan ricotta and mozzarella. Use a plant-based béchamel sauce made with non-dairy milk and butter to keep the flavors rich and creamy.
5. Try Pesto:
For a burst of fresh flavor, swirl a few tablespoons of pesto into the butternut squash filling. It adds a fresh herbal flavor that complements the sweetness of the squash beautifully.
Expert Quote:
“As a chef, I find butternut squash to be a perfect fit for lasagna. Its natural sweetness balances out the richness of the cheese and the depth of the béchamel sauce. It’s an ideal way to introduce more vegetables into a traditionally indulgent dish, while still preserving that comforting lasagna experience. Plus, it’s a great way to incorporate seasonal ingredients into your cooking, especially during the fall and winter months.”

Helpful Tips for the Perfect Butternut Squash Lasagna
- Roast the Squash for Maximum Flavor:
Roasting the butternut squash instead of boiling it enhances its natural sweetness and gives it a caramelized, rich flavor. It makes a big difference in the depth of taste. - Use Fresh Noodles for a Softer Texture:
While no-boil noodles are convenient, using freshly cooked pasta noodles can make your lasagna layers extra soft. Just be sure to cook them al dente to prevent them from becoming mushy during baking. - Add Extra Greens:
If you want to increase the nutritional value, consider adding more greens like kale, chard, or even broccoli to the spinach. These vegetables complement the sweet butternut squash and add a nice texture. - Let It Rest:
Allow the lasagna to cool for at least 10 minutes before cutting into it. This gives the layers time to set and makes it easier to serve. It also enhances the flavors. - Freeze Leftovers:
Butternut squash lasagna freezes beautifully. Store any leftovers in an airtight container for up to 3 months. Simply reheat in the oven, covered with foil, until warmed through.
