Step‑by‑Step Instructions for Roasted Vegetable Lasagna with Creamy Béchamel Sauce
Step 1: Prepare Vegetables
Preheat the oven to 425°F (220°C). In a large mixing bowl, toss together diced zucchini, eggplant, red and yellow bell peppers, and red onion with olive oil, dried Italian herbs, salt, and black pepper. Spread these vegetables evenly on a baking sheet and roast for 20-25 minutes, stirring once halfway through, until they are caramelized and fork-tender with a nice golden color.
Step 2: Make Béchamel Sauce
While the vegetables are roasting, prepare the béchamel sauce. In a medium saucepan, melt 4 tablespoons of unsalted butter over medium heat. Whisk in ¼ cup of all-purpose flour, cooking for 1-2 minutes until bubbly. Gradually add in 3 cups of warmed whole milk, whisking continuously until the mixture thickens, resembling a creamy consistency. Stir in a pinch of ground nutmeg, salt, white pepper, and ½ cup of grated Parmesan cheese until smooth and glossy.
Step 3: Assemble Lasagna
In a rectangular baking dish, start layering your ingredients for the Roasted Vegetable Lasagna. Begin with a layer of roasted vegetables, followed by a thin layer of béchamel sauce, and then place a layer of no-boil lasagna noodles. Repeat the layering process until all ingredients are used, ensuring the last layer is béchamel sauce topped with a generous sprinkle of shredded mozzarella cheese for a deliciously cheesy finish.
Step 4: Bake
Cover the assembled lasagna with foil to lock in moisture and bake in the preheated oven at 375°F (190°C) for 25 minutes. After this time, carefully remove the foil and continue baking for an additional 15 minutes. The top should be bubbly and golden brown, with the edges slightly crisped for that perfect texture.
Step 5: Finish and Serve
Once done, remove the lasagna from the oven and let it rest for about 10 minutes. This allows the layers to set and makes slicing easier. Garnish your Roasted Vegetable Lasagna with fresh basil leaves, adding a pop of color and flavor before serving. Enjoy this comforting homemade meal with friends or family!

Make Ahead Options
For busy home cooks, this Roasted Vegetable Lasagna with Creamy Béchamel Sauce is a dream come true for meal prep!

This way, you’ll have a delightful homemade meal ready with minimal effort, making dinner time stress-free!

Roasted Vegetable Lasagna Recipe FAQs
How do I choose the best vegetables for roasting?
Absolutely! When selecting your vegetables, look for firm, shiny zucchini and eggplants without dark spots all over. Colorful bell peppers should also feel heavy for their size. Freshness is key for enhancing the flavors in your lasagna. For best results, choose seasonal produce that shines in your local markets!
What’s the best way to store leftovers?
Very simple! Store your leftover Roasted Vegetable Lasagna in an airtight container in the refrigerator for up to 3-4 days. Just reheat individual portions in the oven at 350°F (175°C) for about 15-20 minutes for an optimal texture. Enjoying it as leftovers can be just as comforting—if not more so!
Can I freeze Roasted Vegetable Lasagna?
Absolutely! Freezing is a great way to enjoy your lasagna later. To freeze, cover it tightly with plastic wrap, then aluminum foil, and place it in a freezer-safe container for up to 3 months. When you’re ready to eat, thaw it overnight in the fridge. Reheat at 350°F (175°C) for about 25-30 minutes once it’s fully thawed.
What should I do if my béchamel sauce isn’t thickening?
If your béchamel sauce isn’t thickening, don’t worry! First, ensure you’re whisking continuously while adding the milk—it should be warmed for best results. If it’s still too thin, let it cook a little longer on medium heat, whisking constantly, until it thickens up. If you find it clumpy, you can pour it through a fine mesh strainer to achieve that smooth, creamy texture!
Is this recipe suitable for gluten-free diets?
Yes! To make your Roasted Vegetable Lasagna gluten-free, simply substitute all-purpose flour with a gluten-free flour blend when making the béchamel sauce, and use gluten-free no-boil lasagna noodles. Always check the labels to ensure all your ingredients are gluten-free, especially the sauces and cheeses!
Can I make this dish ahead of time?
Very much so! You can prepare your Roasted Vegetable Lasagna up to a day in advance. Assemble it completely, cover it tightly, and keep it refrigerated until you’re ready to bake. Just remember to adjust the baking time slightly if baking directly from the fridge, increasing it by about 10-15 minutes—for that golden, bubbling finish!
