How to Make Vegetable Lasagna with White Sauce

  1. Prepare the Vegetables:
    • Preheat your oven to 400°F (200°C). Toss the zucchini, yellow squash, bell peppers, and mushrooms with olive oil, salt, and pepper. Spread them on a baking sheet and roast for 20-25 minutes until tender.
  2. Make the White Sauce:
    • In a medium saucepan, melt the butter over medium heat. Add the flour and whisk continuously for about 2 minutes until it forms a roux. Gradually add the milk, whisking constantly to avoid lumps. Cook until the sauce thickens, about 5-7 minutes. Stir in the Parmesan cheese, salt, pepper, and nutmeg.
  3. Assemble the Lasagna:
    • Preheat your oven to 375°F (190°C). In a large baking dish, spread a thin layer of white sauce. Place a layer of lasagna noodles over the sauce. Add a layer of ricotta cheese, roasted vegetables, baby spinach, and a sprinkle of mozzarella cheese. Repeat the layers, ending with a layer of noodles topped with white sauce and a final sprinkle of mozzarella and Parmesan cheese.
  4. Bake:
    • Cover the baking dish with aluminum foil and bake for 25 minutes. Remove the foil and bake for an additional 15 minutes, until the top is golden and bubbly.
  5. Serve:
    • Let the lasagna cool for about 10 minutes before slicing. Garnish with fresh basil and serve.
