Main ingredients

  • 9 pieces lasagna noodles Cook according to package instructions.
  • 2 tablespoons olive oil For sautéing.
  • 1 medium onion, finely chopped
  • 3 cloves garlic, minced
  • 1 pound mushrooms (cremini or button), sliced
  • ½ teaspoon dried thyme
  • Salt and pepper, to taste Adjust based on preference.
  • 3 cups marinara sauce For layering.
  • 2 cups ricotta cheese
  • 1 cup shredded mozzarella cheese
  • ½ cup grated Parmesan cheese
  • 2 cups fresh spinach leaves, chopped
  • Fresh basil leaves, for garnish Add before serving.

Instructions
 

Preparation

  • Preheat the oven to 375°F (190°C) and grease a 9×13-inch baking dish.
  • Bring salted water to a boil and cook the lasagna noodles until they're al dente. Drain them and set aside.
  • In a skillet, heat olive oil over medium heat. Sauté the onion for about 3–4 minutes until translucent, then add the minced garlic for another minute.
  • Stir in the sliced mushrooms along with thyme, salt, and pepper. Cook until the mushrooms are tender, then add the spinach and cook until just wilted. Remove from heat.

Assembly

  • Begin with a layer of marinara sauce in your baking dish. Place 3 noodles on top, followed by half of the ricotta, half of the mushroom mixture, and a third of the mozzarella and Parmesan.
  • Repeat the layers and finish with more marinara sauce and the remaining cheeses.

Baking

  • Cover the dish with foil and bake for 25 minutes.
  • Remove the foil and bake for an additional 10–15 minutes, allowing the cheese to become bubbly and golden.

Serving

  • Let the lasagna cool slightly, then garnish with fresh basil before serving warm.

Notes

This lasagna is a great standalone dish but can be paired with a crisp salad or garlic bread. Store leftovers in an airtight container in the refrigerator for up to 3-4 days, or freeze them for up to 3 months.
