For the Creamy Béchamel Sauce
4 tablespoons unsalted butter
4 tablespoons all-purpose flour
4 cups whole milk
1 cup heavy cream
4 cloves garlic, minced
1 small yellow onion or 2 shallots, finely diced
¼ teaspoon ground nutmeg
1 teaspoon salt
½ teaspoon black pepper
1 tablespoon fresh chopped rosemary
For the Cheese Layer
2 cups freshly grated Parmesan cheese
2 cups shredded mozzarella cheese
1 cup ricotta cheese (optional)
For Assembly
9–12 lasagna noodles, cooked or no-boil
1 tablespoon fresh chopped rosemary
½ teaspoon paprika or red pepper flakes (optional)
Instructions
Roast the Butternut Squash
Preheat the oven to 400°F (200°C).
Place the cubed butternut squash on a baking sheet. Drizzle with olive oil and season with salt and pepper. Toss to coat evenly.
Roast for 25–30 minutes until tender and lightly caramelized. Remove from the oven and set aside.
Prepare the Béchamel Sauce
In a large saucepan, melt the butter over medium heat. Add the onion and cook for 3–4 minutes until softened.
Stir in the garlic and cook for 1 minute.
Whisk in the flour and cook for 1–2 minutes, stirring constantly.
Gradually pour in the milk and heavy cream while whisking continuously to prevent lumps.
Cook for 5–7 minutes until thickened.
Season with rosemary, nutmeg, salt, and black pepper. Remove from heat.
Prepare the Baking Dish
Lightly grease a 9×13-inch baking dish.
Spread a thin layer of béchamel sauce across the bottom.
Assemble the Lasagna
Arrange a layer of lasagna noodles over the sauce.
Spread a portion of roasted squash over the noodles.
Spoon béchamel sauce over the squash.
Sprinkle Parmesan and mozzarella cheese evenly.
Repeat the layers until all ingredients are used, finishing with béchamel sauce and a generous layer of cheese on top.
Bake the Lasagna
Cover with foil and bake at 375°F (190°C) for 30 minutes.
Remove the foil and continue baking for 15–20 minutes until golden and bubbling.
Rest Before Serving
Allow the lasagna to rest for 15 minutes before slicing. Garnish with fresh rosemary and extra Parmesan if desired.
Tips
Roast for Maximum Flavor
Roasting caramelizes the squash and enhances its natural sweetness.
Cut Uniform Cubes
Evenly sized squash pieces cook consistently and create better layers.
Use Fresh Herbs
Fresh rosemary provides the best aroma and flavor for this recipe.
Whisk the Sauce Constantly
Continuous whisking prevents lumps and creates a silky béchamel.
Don’t Skip Nutmeg
A small amount adds classic depth to cream-based sauces.
Allow the Sauce to Thicken
A properly thickened sauce helps maintain clean lasagna layers.
Shred Your Own Cheese
Freshly grated cheese melts more smoothly than pre-shredded varieties.
Rest Before Cutting
Resting allows the layers to set and prevents a runny lasagna.
Use No-Boil Noodles Carefully
Ensure enough sauce surrounds no-boil noodles so they soften properly.
Make It Ahead
Assemble the lasagna a day in advance and refrigerate until ready to bake.
