This recipe crafts a hearty and comforting vegetarian lasagna featuring tender butternut squash and fresh spinach layered with whole wheat or regular lasagna noodles. A creamy béchamel sauce, complemented by Parmesan and mozzarella cheeses, binds the savory components together. It's a delightful and substantial dish perfect for a family meal or entertaining.
1. For the butternut squash, ensure it's cooked until fork-tender, as undercooked squash can be firm in the final dish. Roasting the squash before adding it to the filling can deepen its flavor significantly. Toss with a little olive oil, salt, and pepper, then roast at 400°F (200°C) until caramelized. 2. When making the béchamel, gradually add the milk while whisking constantly to prevent lumps. Cook it until it coats the back of a spoon, but isn't too thick, as it will thicken further in the oven. Season generously with salt, white pepper, and a pinch of nutmeg for classic béchamel flavor. 3. Always let the lasagna rest for at least 15-20 minutes after baking before slicing. This allows the layers to set, preventing it from collapsing and ensuring clean, beautiful slices.
