Step-by-Step Instructions
- In a large skillet, heat 2 tablespoons of olive oil over medium-high heat. Add 1 ½ cups of chopped yellow onion, 1 red bell pepper (diced), 8 ounces of chopped cremini mushrooms, and 2 medium diced zucchinis. Sauté for 7-8 minutes until softened and slightly caramelized. Stir in 4 minced garlic cloves and cook for an additional 30 seconds until fragrant.
- Reduce heat to low. Stir in 48 ounces of marinara sauce, 1 teaspoon of dried Italian seasoning, salt, pepper, and a pinch of crushed red pepper flakes. Simmer for 10-15 minutes, stirring occasionally. Fold in 5 ounces of chopped baby spinach, letting it wilt into the sauce.
- In a medium bowl, beat 1 egg until well combined. Add in 1 cup of ricotta cheese and mix until smooth and creamy.
- Preheat your oven to 375°F (190°C). Spread 1 cup of marinara sauce on the bottom of a 9x13-inch baking dish. Place 3 oven-ready lasagna noodles on top, followed by half of the ricotta mixture, and a third of the 16 ounces of shredded mozzarella and ½ cup of grated Parmesan cheese. Repeat the layers, finishing with the noodles topped with remaining sauce, mozzarella, and Parmesan.
- Cover the assembled lasagna tightly with aluminum foil and bake for 35 minutes. Carefully remove the foil and continue baking for an additional 10-15 minutes until bubbly and golden brown.
- Let the lasagna rest for 15 minutes before slicing. Garnish with fresh basil or parsley if desired.
