Description

A deliciously lighter take on classic lasagna, layering tender zucchini planks, sautéed mushrooms, fresh spinach, and a blend of creamy cheeses with savory marinara sauce. This oven-ready lasagna is packed with flavor and perfect for a comforting, vegetable-rich dinner.


Ingredients

Scale
  • 3 tablespoons extra-virgin olive oil, divided

  • 1 pound cremini mushrooms, thinly sliced

  • 1 clove garlic, minced

  • ½ teaspoon salt

  • ¼ teaspoon ground pepper

  • 1 (11-ounce) package baby spinach

  • 1 large egg, lightly beaten

  • 1 (15-ounce) container part-skim ricotta cheese

  • 1½ cups shredded part-skim mozzarella cheese, divided

  • 1 cup grated Parmesan cheese, divided

  • 1 (25-ounce) jar low-sodium marinara sauce, divided

  • 6 sheets oven-ready lasagna noodles

  • 1 medium zucchini, cut lengthwise into 1/8-inch planks

  • Chopped fresh basil and/or parsley for garnish


Instructions

  • Preheat oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish.

  • Heat 1 tablespoon olive oil in a large skillet over medium heat. Add sliced mushrooms, garlic, salt, and pepper. Cook until mushrooms release moisture and become tender, about 6–8 minutes.

  • Add spinach to the skillet and cook until wilted, about 2–3 minutes. Remove from heat and let cool slightly.

  • In a medium bowl, combine ricotta cheese, egg, half of the mozzarella, half of the Parmesan, and the cooked mushroom-spinach mixture. Mix well.

  • Spread ½ cup marinara sauce evenly on the bottom of the prepared baking dish.

  • Layer 3 lasagna noodles over the sauce. Spread half of the ricotta mixture over noodles. Top with half of the zucchini planks, then 1 cup marinara sauce.

  • Repeat layers: noodles, remaining ricotta mixture, zucchini planks, marinara sauce.

  • Top with remaining 3 noodles, sauce, mozzarella, and Parmesan cheeses. Drizzle remaining 2 tablespoons olive oil over the top.

  • Cover with foil and bake for 35 minutes. Remove foil and bake an additional 15 minutes until cheese is bubbly and golden.

  • Let lasagna rest 10 minutes before serving. Garnish with chopped fresh basil or parsley.

Notes

  • Use oven-ready noodles for a quicker preparation without boiling.

  • Feel free to substitute cremini mushrooms with white or portobello.

  • Zucchini slices can be grilled or lightly sautéed if you prefer softer layers.
