Description
Delicious and hearty vegetable lasagna packed with layers of fresh vegetables and creamy ricotta cheese.
Ingredients
Scale
- 2 tablespoons (30 ml) olive oil
- 1 ½ cups (about 1 medium) yellow onion, diced
- 1 whole (about 6–7 oz / 170-200 g) red bell pepper, diced
- 8 ounces (225 g) cremini mushrooms, sliced
- 2 medium (about 12 oz / 340 g) zucchini, sliced thin
- 4 cloves garlic, minced
- 48 ounces (1360 g) marinara sauce, store-bought or homemade
- 1 teaspoon dried Italian seasoning
- Salt and pepper, to taste
- 2 pinches crushed red pepper flakes
- ¼ cup (15 g) fresh parsley, chopped
- 5 ounces (140 g) fresh spinach, coarsely chopped
- 1 whole large egg, beaten
- 1 cup (245 g) ricotta cheese, preferably whole milk, lightly drained
- 9 oven-ready lasagna noodles
- 16 ounces (454 g, about 4 cups) shredded low-moisture mozzarella cheese
- ½ cup (50 g) freshly grated Parmesan cheese
- Optional: Fresh basil or parsley for garnish
Instructions
- Step 1: Preheat your oven to 375°F (190°C) and allow it to fully heat before baking.

- Step 2: Heat olive oil in a large skillet over medium-high heat. Add the diced onion, red bell pepper, and sliced zucchini. Sauté for about 5 to 7 minutes until softened, adjusting heat to medium if vegetables brown too quickly.

- Step 3: Stir in the minced garlic and cook for an additional 1 minute until fragrant.

- Step 4: Pour in the marinara sauce along with dried Italian seasoning, salt, pepper, and crushed red pepper flakes. Let the mixture simmer for 5 to 10 minutes to allow the flavors to meld and vegetables to be coated evenly. If the sauce becomes too watery, stir in 2 tablespoons (16 g) of cornstarch before layering.

- Step 5: In a mixing bowl, combine ricotta cheese with the beaten egg, salt, and pepper. Mix until smooth and creamy.

- Step 6: In the baking dish, assemble the lasagna by layering as follows:

- Step 7: First layer: Spread a thin layer of the vegetable and marinara sauce mixture on the bottom.

- Step 8: Second layer: Arrange 3 oven-ready noodles over the sauce.

- Step 9: Third layer: Spread a portion of the ricotta mixture evenly over the noodles.

- Step 10: Fourth layer: Add a layer of sautéed vegetables and spinach.

- Step 11: Fifth layer: Sprinkle shredded mozzarella cheese over the vegetables.

- Step 12: Repeat layering two more times, finishing with noodles topped with remaining sauce and mozzarella. Sprinkle Parmesan cheese evenly on top.

- Step 13: Cover the baking dish tightly with aluminum foil. Bake in the preheated oven at 375°F (190°C) for 30 minutes. Rotate the lasagna 180 degrees halfway through baking for even cooking and melting. If the cheese is not melted properly near the end, increase oven temperature to 400°F (204°C) and bake an additional 5 minutes while monitoring closely.

- Step 14: Remove the lasagna from the oven and let it rest for 15 minutes without uncovering. This is critical to allow the layers to set and the dish to firm up, making it easier to cut and serve without becoming soupy.

Notes
- Room Temperature: Store leftovers in an airtight container at room temperature and consume within 2 days for best texture and flavor.
- Refrigeration: Place cooled lasagna in an airtight container, refrigerate up to 5 days.
- Freezing: Wrap tightly in plastic wrap and aluminum foil or store in a freezer-safe container. Freeze for up to 3 months. Thaw overnight in the refrigerator before reheating.
- Use oven-ready lasagna noodles to save time but ensure proper layering and cooking to avoid toughness.
- Drain ricotta lightly to reduce moisture and prevent sogginess.
- Use fresh spinach with vibrant green leaves or well-drained frozen spinach.
- Use low-moisture mozzarella for better melting; avoid fresh mozzarella that may make the dish watery.
- Sauté vegetables just until softened to maintain their structure in the final dish.
- Adjust seasoning by tasting your vegetable sauce before layering to ensure balance.
- If the vegetables brown too fast during sautéing, reduce to medium heat and extend cooking time to 5-7 minutes.
- Reheat leftovers in a 350°F (177°C) oven for 20-25 minutes until heated through. Cover with foil to prevent over-browning or drying out.
- Serve with a crunchy side salad or garlic knots to complement the vegetable lasagna.
- Roasted asparagus or sautéed green beans are excellent vegetable sides to accompany this dish.
- Garnish with fresh basil, chopped parsley, or a drizzle of olive oil for added aroma and flavor.
- Substitute zucchini with yellow squash or asparagus for seasonal variations.
- Use spiralized zucchini for a lighter layering option.
- Make lasagna rolls or stuff bell peppers with this vegetable filling for an alternate presentation.
- Select firm zucchini with shiny skin for best texture.
- Choose a high-quality robust marinara sauce without added sugars for balanced flavor.
- Freshly grate Parmesan cheese to add deeper flavor than pre-grated versions.
- Use whole milk ricotta cheese for creaminess and texture.
- Fresh vegetables add vibrancy and seasonal freshness, but frozen can be used if well drained.
