Instructions
 

Preheat the Oven

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

Cook Lasagna Noodles

  • Bring a pot of salted water to a boil. Add the lasagna noodles and cook according to package instructions until al dente. Drain well and set aside to cool slightly.

Prepare Mushroom Filling

  • In a large skillet, heat olive oil over medium heat. Sauté the onion for about 3–4 minutes until translucent. Add minced garlic and cook for an additional minute until fragrant.
  • Stir in sliced mushrooms, dried thyme, salt, and pepper. Cook until the mushrooms are tender. Add chopped spinach and cook until wilted. Remove from heat.

Assemble Lasagna

  • Spread a generous layer of marinara sauce over the bottom of the greased baking dish.
  • Place three lasagna noodles side by side on top of the sauce. Spread half of the ricotta cheese over the noodles.
  • Layer half of the mushroom mixture followed by one-third of the mozzarella and Parmesan cheeses.
  • Repeat the layering process with the remaining ingredients, finishing with a layer of marinara sauce and the remaining cheeses on top.

Bake

  • Cover the baking dish with aluminum foil and bake in the preheated oven for 25 minutes.
  • Uncover the lasagna and bake for an additional 10–15 minutes until the cheese is bubbly and golden brown.

Serve

  • Let the lasagna cool for a few minutes. Garnish with fresh basil leaves before slicing into squares and serving warm.

Notes

You can prepare the lasagna in advance and refrigerate overnight. Consider using no-boil lasagna noodles, adding more vegetables like zucchini or bell peppers, or experimenting with different cheeses.
