Ingredients

• 2 medium zucchinis, sliced into 1/4-inch rounds
• 2 medium eggplants, sliced into 1/4-inch rounds
• 2 large red bell peppers, quartered and seeded
• 1 large yellow onion, thinly sliced
• 4 cloves garlic, minced
• 4 cups crushed tomatoes
• 2 tablespoons olive oil
• 1 teaspoon dried oregano
• 1 teaspoon dried basil
• Salt and freshly ground black pepper, to taste
• 12 no-boil lasagna noodles
• 3 cups whole milk
• 4 tablespoons unsalted butter
• 1/4 cup all-purpose flour, sifted
• 2 cups shredded mozzarella cheese
• 1 cup grated Parmesan cheese
• Fresh basil leaves, for garnish

Instructions

1. Preheat your oven to 425°F (220°C). Place the zucchini, eggplant, and bell peppers on a large baking sheet. Drizzle with olive oil and season generously with salt, pepper, and half the dried oregano and basil. Roast vegetables for 35-40 minutes, turning halfway, until edges are caramelized and golden. Remove from oven and let cool slightly.
2. While vegetables roast, prepare the tomato sauce. In a large saucepan over medium heat, sauté the minced garlic and onion in 1 tablespoon olive oil until translucent and fragrant, about 5 minutes. Stir in crushed tomatoes, remaining oregano and basil, salt, and pepper. Simmer gently for 20 minutes, stirring occasionally to deepen flavors.
3. Next, craft the béchamel sauce. Melt butter in a medium saucepan over medium heat. Whisk in the sifted flour and cook for 2 minutes to form a roux, stirring constantly to avoid lumps. Gradually whisk in warm milk, continuing to stir until the sauce thickens and coats the back of a spoon, about 7-10 minutes. Season with salt and pepper to taste.
4. Lower oven temperature to 375°F (190°C) to prepare for baking. In a large lasagna dish, spread a thin layer of tomato sauce on the bottom. Arrange 3 noodles over the sauce-no need to boil no-boil noodles ahead.
5. Layer roasted vegetables evenly over noodles. Spoon on more tomato sauce and drizzle béchamel sauce atop. Sprinkle a generous handful of mozzarella and a light dusting of Parmesan. Repeat layers twice more, finishing with noodles topped by béchamel and the remaining cheeses.
6. Cover the dish with foil and bake for 25 minutes. Remove foil and bake an additional 10 minutes until the top is bubbly and golden brown. For a beautifully browned crust, broil for 1-2 minutes, watching carefully to avoid burning.
7. Let the lasagna rest for 15 minutes before serving. This resting time allows the layers to settle, making it easier to cut clean slices and ensuring that every bite is moist and flavorful.

Tips for Success

• Roasting vegetables: Cut vegetables evenly for uniform roasting. Turning them halfway through ensures caramelization on all sides, which boosts natural umami.
• Tomato sauce: Fresh garlic and slow simmering coax out complexity-avoid rushing this step.
• Béchamel tips: Use warm milk to prevent lumps and whisk continuously; patience here rewards you with luscious creaminess.
• Assembling: No-boil noodles save time, but if preferred, boil and cool them as a backup option.
• Advance prep: Roast vegetables and prepare sauces up to 24 hours ahead, then assemble just before baking for ease and enhanced melding of flavors.
• Customization: Swap in seasonal veggies like butternut squash or mushrooms to keep the flavor profile exciting year-round.

Serving Suggestions

Serve your roasted vegetable lasagna warm, garnished with fresh basil leaves and a light drizzle of good-quality extra virgin olive oil to add an herbaceous finish. Pair with a crisp green salad tossed in lemon vinaigrette to balance richness. For an inviting presentation, slice generously and plate with a sprinkle of extra Parmesan and a few cracked black pepper flakes. Enjoy with crusty rustic bread to soak up every luscious bite.

Q&A

Q&A: Layers of Flavor – The Ultimate Roasted Vegetable Lasagna Guide

Q1: What makes roasted vegetable lasagna different from traditional lasagna?
A1: Unlike classic lasagna, which often relies heavily on meat and ricotta, roasted vegetable lasagna celebrates the deep, caramelized sweetness of perfectly roasted veggies. This technique adds layers of smoky, concentrated flavor that transform each bite into a complex, mouthwatering experience-making it just as satisfying for vegetarians and carnivores alike.

Q2: Which vegetables are best for roasting in this lasagna?
A2: The magic lies in root vegetables like sweet potatoes, carrots, and beets, alongside hearty options like zucchini, bell peppers, and eggplant. Roasting brings out their natural sugars and tender textures, creating a rich tapestry of flavor and color that shines between the sheets of pasta.

Q3: How do you roast vegetables to maximize flavor for the lasagna?
A3: Start by cutting vegetables into uniform pieces to ensure even cooking. Toss them lightly in olive oil, salt, and herbs like thyme or rosemary, then roast at a high temperature (around 425°F/220°C) until edges are caramelized and centers tender. This Maillard reaction is what unlocks the savory, almost sweet depths of flavor essential to the dish.

Q4: Can the sauce be adapted for a vegetarian-friendly lasagna?
A4: Absolutely! A classic tomato sauce enriched with garlic, onions, and fresh basil works beautifully. For creaminess, consider a ricotta and spinach mixture or a béchamel sauce with nutmeg. These layers add luscious texture and balance the roasted vegetables’ earthiness, creating a harmonious symphony of taste.

Q5: How do you assemble the layers to ensure every bite is balanced?
A5: Think of lasagna layering as building edible architecture: start with a thin layer of sauce to prevent sticking, then noodles, a hearty spread of roasted veggies, dollops of cheese or béchamel, and repeat. The key is moderation in each layer to keep the integrity of flavors distinct yet complementary-no one ingredient should overpower.

Q6: Any tips for baking the perfect roasted vegetable lasagna?
A6: Cover the lasagna with foil for the first 30-40 minutes to trap moisture and heat evenly, then remove it for the last 10-15 minutes to achieve a golden, bubbling cheese crust. Let it rest before cutting to allow flavors to meld and layers to set-patience here yields a perfectly cohesive slice.

Q7: Can this recipe be prepared ahead of time?
A7: Yes! Lasagna is a superb make-ahead dish. Assemble it a day in advance and refrigerate. When ready, bake it a bit longer than usual to ensure it’s heated through. This resting time often enhances flavor melding, making the roasted vegetable layers even more vibrant and irresistible.

Q8: What wine pairing would elevate the roasted vegetable lasagna experience?
A8: A bright, medium-bodied red like Chianti or a fruity Pinot Noir complements the earthy, caramelized notes of the roasted veggies without overshadowing them. For white wine lovers, a buttery Chardonnay or a dry, herbaceous Sauvignon Blanc can also enhance the dish’s complexity.
