Ingredients
This recipe serves 8-10 people and fits a standard 9×13-inch baking dish. Feel free to adjust quantities based on your needs.
For the Vegetable Filling:
- 2 medium zucchinis, sliced into thin rounds (about 1/4-inch thick)
- 1 large red bell pepper, diced
- 1 large yellow bell pepper, diced
- 8 ounces cremini mushrooms, sliced
- 3 cups fresh spinach, roughly chopped
- 2 tablespoons olive oil
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1 teaspoon dried oregano
- 1 teaspoon garlic powder
For the Tomato Sauce:
- 2 tablespoons olive oil
- 1 medium yellow onion, finely chopped
- 3 garlic cloves, minced
- 1 (28-ounce) can crushed tomatoes
- 1 (15-ounce) can tomato sauce
- 1 tablespoon tomato paste
- 1 teaspoon dried basil
- 1 teaspoon dried oregano
- 1/2 teaspoon red pepper flakes (optional, for a kick)
- Salt and pepper to taste
- 1 teaspoon sugar (optional, to balance acidity)
For the Cheese Filling:
- 15 ounces ricotta cheese (whole milk or part-skim)
- 1 large egg
- 1/2 cup grated Parmesan cheese
- 2 cups shredded mozzarella cheese, divided
- 1 teaspoon dried parsley (or 1 tablespoon fresh, chopped)
- Salt and pepper to taste
For Assembly:
- 12-15 lasagna noodles (no-boil or traditional, cooked according to package instructions)
- 1 cup shredded mozzarella cheese (for topping)
- 1/4 cup grated Parmesan cheese (for topping)
Equipment Needed
- Large skillet or sauté pan
- Medium saucepan
- Baking sheet (for roasting vegetables)
- 9×13-inch baking dish
- Mixing bowls
- Wooden spoon or spatula
- Aluminum foil
Step-by-Step Instructions
Step 1: Prepare the Vegetables
Preheat your oven to 400°F (200°C). Roasting the vegetables enhances their natural sweetness and removes excess moisture, preventing a soggy lasagna.
- Spread the sliced zucchini, diced bell peppers, and mushrooms on a large baking sheet in a single layer.
- Drizzle with 2 tablespoons of olive oil and sprinkle with salt, pepper, oregano, and garlic powder. Toss to coat evenly.
- Roast in the preheated oven for 20-25 minutes, or until the vegetables are tender and slightly caramelized, flipping halfway through.
- Remove from the oven and set aside. Once cooled slightly, stir in the chopped fresh spinach—it will wilt from the residual heat.
Step 2: Make the Tomato Sauce
While the vegetables roast, prepare the sauce. A homemade tomato sauce adds depth and freshness to the lasagna, but you can use a high-quality store-bought marinara in a pinch.
- Heat 2 tablespoons of olive oil in a medium saucepan over medium heat.
- Add the chopped onion and sauté for 4-5 minutes, until soft and translucent.
- Stir in the minced garlic and cook for another 30 seconds, until fragrant.
- Add the crushed tomatoes, tomato sauce, and tomato paste. Stir to combine.
- Season with basil, oregano, red pepper flakes (if using), salt, pepper, and sugar. Simmer on low heat for 15-20 minutes, stirring occasionally, until the flavors meld. Adjust seasoning to taste.
Step 3: Prepare the Cheese Filling
The ricotta layer adds creaminess and binds the lasagna together.
- In a mixing bowl, combine the ricotta cheese, egg, 1/2 cup Parmesan, 1 cup of mozzarella, and dried parsley.
- Season with a pinch of salt and pepper. Stir until smooth and well-blended. Set aside.
Step 4: Cook the Noodles (If Using Traditional Lasagna Noodles)
If you’re using no-boil noodles, skip this step—they’ll soften during baking. For traditional noodles:
- Bring a large pot of salted water to a boil.
- Cook the lasagna noodles according to package instructions (usually 8-10 minutes) until al dente.
- Drain and rinse with cold water to prevent sticking. Lay the noodles flat on a clean kitchen towel or parchment paper.
Step 5: Assemble the Lasagna
Now comes the fun part—layering! Preheat your oven to 375°F (190°C) if it’s not already on.
- Spread a thin layer (about 1/2 cup) of tomato sauce on the bottom of the 9×13-inch baking dish to prevent sticking.
- Place a single layer of lasagna noodles over the sauce, overlapping slightly if needed.
- Spread 1/3 of the ricotta mixture evenly over the noodles.
- Spoon 1/3 of the roasted vegetable mixture over the ricotta.
- Drizzle 1 cup of tomato sauce over the vegetables.
- Repeat the layers two more times: noodles, ricotta, vegetables, sauce.
- Finish with a final layer of noodles, the remaining tomato sauce, 1 cup of shredded mozzarella, and 1/4 cup of grated Parmesan.
Step 6: Bake the Lasagna
- Cover the dish with aluminum foil (tent it slightly to avoid sticking to the cheese).
- Bake in the preheated oven for 30 minutes.
- Remove the foil and bake for an additional 15-20 minutes, or until the cheese is golden and bubbly.
- Let the lasagna rest for 15-20 minutes before slicing—this helps it set and makes serving easier.
Tips for the Perfect Vegetable Lasagna
- Control Moisture: Roasting the vegetables is key to avoiding a watery lasagna. Zucchini and mushrooms, in particular, release a lot of liquid when cooked, so don’t skip this step.
- Season Every Layer: Taste and adjust the seasoning in the sauce, vegetables, and ricotta mixture to ensure bold flavor throughout.
- Make Ahead: Assemble the lasagna up to a day in advance, cover it tightly, and refrigerate. When ready to bake, add 10-15 minutes to the covered baking time.
- Freezing: Vegetable lasagna freezes beautifully. Assemble it in a freezer-safe dish, wrap tightly with plastic wrap and foil, and freeze for up to 3 months. Bake from frozen at 375°F, covered, for 60-75 minutes, then uncover and bake until bubbly.
- Cheese Options: Swap mozzarella for provolone or fontina for a twist, or add a sprinkle of goat cheese for tanginess.
Variations to Try
- Mediterranean Twist: Use eggplant, artichoke hearts, and feta cheese instead of zucchini and ricotta.
- Spicy Kick: Add chopped jalapeños to the vegetable mix or increase the red pepper flakes in the sauce.
- Creamy White Lasagna: Replace the tomato sauce with a béchamel sauce made from butter, flour, and milk, seasoned with nutmeg.
- Vegan Version: Substitute ricotta with cashew cheese, use vegan mozzarella, and skip the egg—use a flax egg if needed for binding.
Serving Suggestions
Vegetable lasagna is a meal in itself, but it pairs wonderfully with simple sides:
- Garlic Bread: Perfect for sopping up extra sauce.
- Green Salad: A crisp salad with vinaigrette cuts through the richness.
- Wine: A medium-bodied red like Chianti or a crisp white like Pinot Grigio complements the flavors.
Nutritional Benefits
This vegetable lasagna isn’t just delicious—it’s packed with nutrients. Zucchini and spinach provide vitamins A and C, mushrooms offer B vitamins and antioxidants, and bell peppers are rich in fiber and vitamin C.
