Yields 4-6 servings


  • 6 lasagna noodles
  • 2 medium onions 350 g, sliced
  • 1 lb oyster mushrooms 454 g, sliced
  • 3 cups ricotta cheese 750 g
  • 4 Tbsp freshly grated Parmesan or Romano cheese
  • 2 cups shredded Mozzarella cheese
  • 1 1/2 eggs
  • 1 Tbsp chopped fresh dill
  • 1 Tbsp chopped fresh parsley
  • 4 Tbsp butter or vegetable or olive oil (butter recommended for better flavor)
  • 1 3/4 tsp salt 1 tsp for ricotta filling, 3/4 tsp for sauteed onions and mushrooms
  • 1/2 tsp freshly ground pepper


  1. Preheat oven to 375 F (190 C)
  2. Bring a large pot of lightly salted water to a boil. Cook lasagna noodles in boiling water for 8 to 10 minutes or as per instructions on the package. Drain the noodles and rinse with cold water
  3. In a medium size mixing bowl, combine ricotta cheese with egg, dill, parsley and 1 teaspoon salt. Set aside
  4. Preheat a large skillet with 2 tablespoons butter or oil. Add onions and saute over medium heat for 9-10 minutes, until translucent and golden brown. Add 1/4 tsp salt and 1/4 tsp black pepper when almost done. Transfer into a bowl
  5. Using the same skillet, saute oyster mushrooms with 2 tablespoons butter or oil over high heat for 5-6 minutes
  6. Turn heat to medium, add 1/2 teaspoon salt and 1/4 teaspoon ground pepper, and saute for another 3 minutes
  7. Add onions to mushrooms and continue sauteing over medium heat for another 2-3 minutes. Remove from heat and transfer to a bowl
  8. To assemble lasagna, spread about 1 tablespoon of ricotta cheese filling on the bottom of a 8 x 8 inch baking dish. Arrange 3 noodles on the bottom of the pan (you will need to cut them to needed length).
  9. Spread half of the ricotta cheese filing over noodles. Top with half of oyster mushroom and onion mix, followed by 1 cup mozzarella cheese and 2 tablespoons grated Parmesan cheese.
  10. Repeat another layer
  11. Cover with foil, ensuring that foil does not touch the top of the lasagna
