Roasted vegetable lasagna with béchamel, zucchini, roasted peppers, spinach, and toasted hazelnut crumble topping.
A comforting, vibrant lasagna that layers charred zucchini, peppers, and spinach between creamy béchamel, while a delicate toasted hazelnut crumble adds unexpected crunch and nutty warmth.

This dish begins with a simple, patient roasting of vegetables to deepen their sweetness and color. Slice zucchini into half moons, peppers into wide strips, and keep spinach ready for quick wilting. As vegetables roast, simmer a smooth béchamel that thickens to a rich, glossy coat. The secret is a gentle spoon of nutmeg and a splash of white pepper for warmth without bitterness. An optional parmesan can be whisked into the sauce, or kept separate to preserve a creamier finish. Layering follows, building a fortress of flavor from the base to the top.
Assemble each component with care to preserve textures. Start with a thin blanket of béchamel on the baking dish, then lay sheets of lasagna that hold their shape. Above them, spread a light veil of béchamel, then add roasted zucchini slices, peppers, and a handful of wilted spinach that has released its moisture. Repeat layers until the dish sings with color and height. Finish with a final swirl of béchamel and a sprinkling of grated cheese if desired. Bake until bubbling, fragrant, and golden.
Rustic yet refined, this lasagna embraces seasonal produce boldly.
The hazelnut crumble topping is the unexpected star, offering a toasty, earthy counterpoint to the lush filling. Toast crushed hazelnuts lightly in a dry skillet until fragrant, then fold in a pinch of salt and a whisper of coriander seed to brighten the nuts. Scatter this topping over the lasagna’s final layer before the bake, allowing it to melt into the sauce beneath as it browns. The result is a delicate crunch that contrasts with the creamy béchamel and tender vegetables. This element can be prepared ahead, amplifying flavor over time when stored in an airtight container.
To balance richness, consider a fresh herb oil or a peppery arugula salad on the side. A drizzle of lemon juice can lift the béchamel’s silkiness, while a handful of baby spinach tossed with garlic adds a bright counterpoint. When serving, portions should show visible layers—zucchini ribbons, peppers, and greens peeking through the robe of white sauce. The dish comes together in stages, rewarding patience with depth of flavor and a satisfying, homey finish that still feels sophisticated.
Layering thoughtfully preserves structure and flavor harmony.
The groundwork rests on selecting vegetables that hold shape during baking. Choose firm zucchini and vibrantly colored peppers, ensuring they’re not overly wet after washing. Pat dry to prevent soggy layers, and roast at a high temperature to caramelize edges. Spinach should only just wilt; excess moisture can loosen the layers and dilute the sauce. The béchamel should be thick enough to coat without pooling. If time allows, prepare the sauce a day ahead—the flavors meld and intensify, and the assembly becomes quicker the next day, making weeknight dinners feel unhurried and celebratory.
A careful balance exists between the creamy center and the nutty finish. The hazelnut crumble lends a subtle sweetness and a gentle bite that contrasts with the mild richness of béchamel and the earthiness of vegetables. When breading or cooking steps feel lengthy, consider streamlining by premixing spices and toasting nuts in advance. The constructive point is to maintain the integrity of each component, ensuring that every forkful yields a chorus of textures rather than a single, dominant note. This approach helps the dish stay appealing across seasons.

The béchamel’s role as a unifier cannot be overstated. A glossy, evenly seasoned sauce helps the vegetables appear more vibrant and keeps the lasagna cohesive as it bakes. If the sauce thickens too much, whisk in a touch of milk to restore a silky pour. Conversely, if it’s too thin, cook briefly longer while stirring constantly to avoid scorching. The cheese, optional or integrated, should melt into the sauce rather than overwhelm it, creating a velvet backdrop for the vegetables’ color. Remember, patience during the bake yields cleaner slices later.
For serving, allow the lasagna to rest briefly after removing it from the oven. Resting helps the layers set, making slicing easier and preventing runny portions. A drizzle of olive oil and a final crack of black pepper can brighten the finish. Pair with a light salad of bitter greens to provide a sharp contrast to the lasagna’s mellow richness. This combination is a gentle way to present a substantial dish without feeling heavy, inviting guests to savor each mouthful slowly.

Memory and technique join in every bite, reminding cooks that good ingredients often tell the story themselves. Start with bright peppers roasted until their skins blister, then peel if desired for a smoother texture. Zucchini should emerge with caramelized edges and tender centers, offering a soft bite that harmonizes with the creaminess of béchamel. Spinach leaves can contribute a slight peppery note when lightly wilted, enriching the layer’s green depth. The hazelnut crumble should appear as small, warm islands across the top, giving aroma and a satisfying crunch.
This dish thrives on deliberate timing and clean flavor. Preheat your oven to a steady heat so the layers cook evenly without drying out. Keep a watchful eye during the final 15 minutes to prevent over-browning. If cheese is included, cover the dish loosely with foil for part of the bake to avoid scorching. Serve with a simple accompaniment that enhances rather than competes with the flavors, such as a citrusy vinaigette or a lightly dressed herb salad. The result is a meal that comforts while feeling fresh and modern.
The ingredient list is short, but the technique matters. Good veg selection and precise roasting time make the difference between soggy layers and vibrant, separate flavors. A béchamel that remains silky but not overly thick helps maintain the lasagna’s classic feel, while the hazelnut topping introduces an unusual, premium touch that elevates the dish. If you want to make this ahead, assemble and refrigerate before baking; the flavors will intensify as they rest. This approach suits gatherings or quiet weekends, offering a dish that travels well in memory and in portions.
Finally, consider variations that suit dietary needs without sacrificing essence. For a dairy-free option, swap béchamel for a velvety almond or cashew sauce with a touch of nutrient-rich miso for savory depth. You can substitute spinach with kale for a heartier bite or add mushrooms to deepen umami. The lasagna remains forgiving and adaptable, inviting cooks to experiment with textures and aromatics while preserving its core charm: roasted vegetables, creamy sauce, and a final, toasty crunch that lingers on the palate.
