How to Make Roasted Butternut Squash Lasagna Recipe
Step 1: Roast the Squash
Preheat your oven to 450 degrees Fahrenheit. Spread the diced butternut squash on a large sheet pan and toss with oil and a pinch of salt. Roasting at high heat caramelizes the squash beautifully, drawing out its natural sugars and giving it a tender, golden-brown finish. Flip the squash halfway through to ensure every piece gets that lovely roast.
Step 2: Infuse the Milk
While the squash roasts, gently simmer milk with fresh rosemary and sage. This step infuses the milk with herbal aroma, creating a subtle yet unforgettable base for your sauce that complements the sweetness of the roasted squash perfectly.
Step 3: Prepare the Creamy Sauce
In a saucepan, soften minced garlic in melted butter. Stir in flour and cook for a few minutes to form a roux, which thickens your sauce. Gradually whisk in the infused milk until smooth and simmer until luxuriously thick. Finally, fold the tender roasted squash into the sauce and season to taste — this mixture is the heart of your lasagna.
Step 4: Prep the Lasagna Noodles
Reduce the oven temperature to 375 degrees Fahrenheit and butter your baking dish. To avoid dryness, briefly soak the no-boil lasagna noodles in hot water before assembling—this simple trick ensures they’ll be tender and pliable, creating harmony between the layers.
Step 5: Assemble the Layers
Begin by spooning some sauce into the baking dish, then layer three noodles without overlap. Spread half of the remaining sauce over the noodles and sprinkle with Parmesan. Repeat with noodles, sauce, and Parmesan, finishing with noodles on top. Each layer builds the perfect balance of creamy texture and cheesy flavor.
Step 6: Add Cream and Bake
Whip the heavy cream with a pinch of salt until soft peaks form, then spread it evenly on the top pasta layer to create a cloudlike cap that locks in moisture. Sprinkle the final Parmesan over the cream, cover with foil carefully, and bake for 30 minutes. Remove foil and bake for another 10 to 20 minutes until bubbly and golden. Let rest before slicing to let all flavors meld beautifully.
How to Serve Roasted Butternut Squash Lasagna Recipe
Garnishes
Fresh herbs like chopped sage or rosemary make fantastic garnishes, adding a fresh, green contrast to the rich lasagna. A light drizzle of high-quality olive oil or a sprinkle of toasted pine nuts can also introduce an unexpected pop of texture and flavor that elevates your presentation.
Side Dishes
Pair this lasagna with a crisp, peppery arugula salad tossed in lemon vinaigrette to balance richness with brightness. Roasted Brussels sprouts or sautéed garlic green beans also complement the hearty squash beautifully, rounding out the meal with color and variety.
Creative Ways to Present
Try serving individual portions in small ramekins for cozy, personal servings at dinner parties. Alternatively, top slices with a spoonful of ricotta or dollops of pesto for a fresh twist. For a festive look, layer thin slices of apple or pear on top before baking for a subtle hint of sweetness and eye-catching texture.
Make Ahead and Storage
Storing Leftovers
Leftover roasted butternut squash lasagna keeps beautifully in the fridge for up to 3 days when covered well. The flavors actually deepen overnight, making it an ideal next-day meal that reheats beautifully without losing its creamy texture.
Freezing
This lasagna freezes wonderfully, making it a great make-ahead dish. For best results, freeze fully assembled but unbaked lasagna in an airtight container or wrapped tightly in foil and plastic wrap. It can be frozen for up to 3 months, ready to pop straight into the oven when needed.
Reheating
Reheat in the oven at 350 degrees Fahrenheit, covered loosely with foil to keep the moisture in, until warmed through and bubbly. Microwave reheating is possible for single servings but may cause uneven heating or dryness, so the oven is preferred for best results.
FAQs
Can I use fresh pasta sheets instead of no-boil noodles?
Absolutely! Fresh pasta sheets work wonderfully and often require less soaking time. Keep an eye on the moisture level in your sauce to ensure the lasagna layers cook through evenly.
Is there a good substitute for heavy cream in this recipe?
If you want a lighter option, you can substitute half-and-half or a combination of milk and Greek yogurt, though the topping won’t be quite as rich or hold peaks as well when whipped.
Can I make this recipe vegan or dairy-free?
With some tweaks like using plant-based milk, vegan butter, and dairy-free cheese alternatives, you can adapt this dish. Consider blending silken tofu or cashew cream into the sauce to maintain the creamy texture without dairy.
How do I avoid watery lasagna with no-boil noodles?
Soaking the noodles briefly in hot water before assembly helps them hydrate evenly and prevents a watery dish. Also, be cautious about the moisture content in your sauce—thicker sauces reduce excess liquid during baking.
Can I prepare the sauce and squash ahead of time?
Yes! The squash sauce can be made up to 3 days in advance and stored in the fridge. This makes assembling the lasagna on the day of baking quicker and easier.

Ingredients
Roasted Butternut Squash
- 3 pounds butternut squash, quartered, seeded, peeled, and cut into 1/2-inch dice (about 8 cups)
- 3 tablespoons grapeseed or olive oil
- 1/2 teaspoon salt (for seasoning squash)
Sauce
- 4 cups milk, 2% or whole
- a few sprigs fresh rosemary
- a few sprigs fresh sage
- 1 tablespoon minced garlic
- 4 tablespoons unsalted butter
- 4 tablespoons all-purpose flour
- Salt and freshly ground black pepper, to taste
Assembly
- Nine 7– by 3 1/2-inch sheets dry no-boil lasagne pasta (such as Barilla brand)
- 1 1/3 cups freshly grated Parmesan cheese, divided
- 1 cup heavy cream
- 1/2 teaspoon salt (for whipped cream topping)
- Butter, for greasing baking dish
Instructions
- Roast the Squash: Preheat your oven to 450°F (232°C). Spread the diced butternut squash evenly on one extra-large sheet pan or two standard-sized sheet pans. Toss the squash with 2 tablespoons of oil if using one large pan, or 1 tablespoon per pan if using two. Season with salt and toss again to coat well. Roast in the oven for about 30 minutes, tossing once halfway through, until the squash is tender and starting to turn golden brown.
- Infuse the Milk: While the squash roasts, place the milk in a saucepan along with sprigs of fresh rosemary and sage. Bring to a gentle simmer over medium heat, then reduce to low and let it infuse for 10 minutes. Afterward, strain the milk through a sieve into a pitcher or large measuring cup, removing the herbs.
- Prepare the Sauce: In a large heavy saucepan over moderately low heat, cook the minced garlic in the butter, stirring until softened but not browned. Stir in the flour to make a roux and cook, stirring frequently, for about 3 minutes to remove the raw flour taste. Remove from heat and gradually whisk in the infused milk in a steady stream until smooth. Return to heat and simmer gently for about 10 minutes, whisking occasionally until the sauce thickens. Stir in the roasted squash and season with salt and freshly ground black pepper to taste. The sauce can be prepared up to 3 days in advance and refrigerated with plastic wrap directly on its surface to prevent skin forming.
- Preheat Oven and Prepare Bakeware: Lower the oven temperature to 375°F (190°C). Butter a 9×13-inch baking dish to prevent sticking. For improved noodle texture, if your no-boil noodles tend not to expand well, soak three sheets briefly in hot boiling water before assembly. This step is optional if your noodles perform well without soaking.
- Assemble the Lasagna: Begin by pouring 1 cup of the squash sauce into the bottom of the buttered baking dish—this won’t completely cover the bottom. Layer three lasagna sheets on top, ensuring they do not overlap; use tongs to handle noodles if soaked. Soak the next three noodles if needed. Spread half of the remaining sauce (about 2 cups) evenly over this noodle layer and sprinkle with 1/2 cup Parmesan cheese. Add the next three noodles and soak the final three if using the hot water bath. Spread the remaining sauce over this layer and sprinkle with another 1/2 cup Parmesan. Finish with the final noodle layer.
- Top with Whipped Cream and Bake: In a bowl using an electric mixer (or whisk by hand), beat the heavy cream and 1/2 teaspoon salt until soft peaks form. Spread the whipped cream evenly over the top layer of noodles, ensuring complete coverage. Sprinkle the remaining 1/3 cup Parmesan cheese over the cream layer. Tightly cover the dish with aluminum foil, tenting slightly so it does not touch the cream. Bake in the middle rack of the oven for 30 minutes. Remove the foil and bake for an additional 10 to 20 minutes, until the top is bubbly and golden brown. Let the lasagna rest for 5 minutes before cutting and serving.
Notes
- Soaking the no-boil noodles in hot water before assembly improves their texture but can be omitted if your brand expands properly without soaking.
- The roasted squash and sauce can be prepared up to three days ahead to save time on serving day.
- Cover the surface of the sauce with plastic wrap when storing in the fridge to prevent a skin from forming.
- Use fresh rosemary and sage for best flavor infusion in the milk.
- You can substitute grapeseed oil with olive oil for roasting squash based on preference.
- Allow the lasagna to rest after baking before cutting to ensure cleaner slices.
