Step 1: Roasting the Vegetables
Roasting brings out the natural sweetness of the vegetables and reduces moisture, which prevents soggy lasagna.

- Season and Roast:
- Preheat oven to 425°F (220°C).

- Spread on a baking sheet and roast for 20–25 minutes until slightly caramelized.
Step 2: Making the Béchamel Sauce
Béchamel is a classic French sauce that forms the creamy foundation of this lasagna.
Ingredients for Béchamel:
- 4 tablespoons butter
- 4 tablespoons all-purpose flour
- 4 cups whole milk (warm)
- Salt, pepper, pinch of nutmeg
Instructions:
- Melt the Butter: Use a saucepan over medium heat.
- Add Flour: Whisk in flour to form a roux. Cook for 1–2 minutes.
- Gradually Add Milk: Whisk continuously to avoid lumps.
- Season: Add salt, pepper, and nutmeg. Simmer until thickened to a pourable consistency.
Step 3: Layering the Lasagna
Now the magic happens as you build the layers.
Assembly:
- Spread a layer of béchamel on the bottom of a greased 9×13 inch baking dish.
- Add a layer of lasagna sheets.
- Distribute roasted vegetables evenly.
- Dollop ricotta cheese and drizzle béchamel.
- Sprinkle mozzarella and Parmesan.
- Repeat until all ingredients are used. Top with béchamel and cheese.
Step 4: Baking the Lasagna
Instructions:
- Cover and Bake: Use foil and bake at 375°F (190°C) for 30 minutes.
- Uncover and Finish: Remove foil and bake an additional 10–15 minutes until golden and bubbling.
Step 5: Serving Suggestions
Let the lasagna rest for 10–15 minutes after baking for cleaner slices and better texture.
Serve With:
- A fresh green salad with vinaigrette
- Warm garlic bread or sourdough baguette
