The story behind this recipe

This recipe was born out of a summer garden frenzy. I had more zucchini and bell peppers than I knew what to do with, and I didn’t want to just sauté them all the time. I remembered how my grandma used to layer her vegetables in lasagna, making it feel like a celebration of the season’s best flavors.
One afternoon, I threw together this veggie-packed version, improvising with what I had on hand. It turned into a dish that’s hearty enough to satisfy, but still bright and fresh—kind of a nod to those lazy, sunny afternoons in the garden. Now, it’s become a staple for when I want comfort without losing that vibrant, seasonal punch.

Trivia and historical tidbits

Vegetable lasagna has roots in Italian cuisine but gained popularity in American kitchens during the health food movement of the 1960s and 70s.
Early veggie lasagna recipes often used canned vegetables, but today’s versions celebrate fresh, seasonal produce for vibrant flavor.
In some regions, this dish evolved as a way to make hearty, meatless meals that still felt indulgent and satisfying.
The colorful layers of vegetables in this dish are inspired by traditional Italian vegetable stews, reimagined in lasagna form.

Ingredient breakdown: key components

Zucchini: I slice it thin so it cooks evenly and layers nicely, releasing a sweet, grassy aroma that fills the kitchen. Feel free to swap for yellow squash for a slightly sweeter note.
Ricotta: I prefer whole-milk ricotta for creaminess and richness that melts into the layers. For a lighter version, try part-skim, but you might notice a less velvety texture.
Spinach: I wilt it first to remove excess moisture and darken its vibrant color. Frozen spinach works in a pinch, just squeeze out the water to avoid sogginess.
Bell Peppers: Roasted until smoky and tender, they add a sweet, caramelized depth. Use a mix of colors for visual pop, or skip if you want to keep it simple.
Tomato Sauce: I simmer it with garlic and herbs until it’s thick and fragrant, with a tangy brightness. Canned crushed tomatoes are a reliable shortcut; fresh can work if in season.
Lasagna Noodles: I use no-boil noodles for convenience, but traditional ones work better if pre-cooked. Just ensure they’re fully submerged in sauce to prevent dryness.
Cheese: A generous layer of mozzarella melts into gooey goodness, while Parmesan adds a salty, nutty kick. Feel free to top with fresh basil for a fragrant finish.

Notes for ingredient swaps

Dairy-Free: Swap ricotta for blended silken tofu—creamy but with a more neutral flavor that absorbs herbs well.
Vegan: Use vegan cheese and plant-based béchamel instead of traditional cheese layers—less cheesy, more savory.
Gluten-Free: Replace lasagna noodles with thinly sliced zucchini or gluten-free pasta—keep an eye on moisture levels to prevent sogginess.
Low-Sodium: Choose no-salt-added canned tomatoes and unsalted cheese—let the herbs and vegetables shine more clearly.
Extra-Flavor: Add a splash of balsamic vinegar to your tomato sauce for a deeper, slightly sweet tang—brightens the whole dish.
Rich & Oily: Use a splash of olive oil in the tomato sauce or veggies—enhances richness without overwhelming the dish.
Herb Variations: Toss in fresh basil or thyme instead of oregano—fresh herbs add a fragrant, lively note to the layers.

Step-by-step guide to vegetable lasagna

Preheat your oven to 200°C (390°F). Slice zucchini into thin rounds, about 3mm thick. Roast on a baking sheet for 15 minutes until slightly golden and fragrant. Set aside to cool slightly.
Prepare your spinach by wilting it in a dry skillet over medium heat for 2-3 minutes, just until wilted and dark green. Squeeze out excess moisture and chop roughly. Set aside.
Cook or soak your lasagna noodles according to package instructions if using traditional noodles. For no-boil noodles, skip this step. Keep them ready in a lightly oiled dish to prevent sticking.
Make the tomato sauce: In a saucepan, heat 2 tablespoons olive oil over medium heat. Sauté 3 minced garlic cloves until fragrant, about 30 seconds. Add 400g crushed tomatoes, 1 teaspoon dried oregano, and salt to taste. Simmer for 15 minutes until thick and aromatic. Set aside.
In a mixing bowl, combine 1 cup ricotta, 1 beaten egg, ½ cup grated Parmesan, a pinch of salt, and some freshly cracked black pepper. Mix until smooth.
Layer the lasagna: In a 9×13 inch (23×33 cm) baking dish, spread a thin layer of tomato sauce on the bottom. Place a layer of noodles over the sauce. Spread a third of the ricotta mixture, then layer roasted zucchini and wilted spinach. Repeat layers until all ingredients are used, finishing with a layer of noodles topped with sauce and shredded mozzarella.
Cover with foil and bake at 200°C (390°F) for 35 minutes. Remove foil and bake an additional 10 minutes until bubbly and golden on top. Let rest for 10-15 minutes to set before slicing.
Resting & Finishing: Rest the lasagna on a wire rack for at least 10 minutes. Slice carefully with a sharp knife, ensuring clean edges. Serve warm, garnished with fresh basil if desired.

Let the lasagna rest uncovered for at least 10 minutes. Slice with a sharp knife, serving warm with a sprinkle of fresh basil or extra Parmesan if desired.
