How to Make Mushroom Spinach Lasagna Vegetarian Step-by-Step
- Step 1: Preheat your oven to 375°F (190°C).
- Step 2: Finely chop your onion and mince the garlic.
- Step 3: Clean the mushrooms thoroughly with a damp cloth and slice them.
- Step 4: If using fresh spinach, quickly blanch it in boiling water for about 30 seconds until wilted, then immediately transfer to an ice bath. Once cool, squeeze out as much water as you possibly can. If using frozen, thaw and squeeze dry. Chop the squeezed spinach roughly.
- Step 5: Heat about 2 tablespoons of olive oil in a large skillet or Dutch oven over medium heat. Add the chopped onion and cook until softened, about 5-7 minutes. Add the minced garlic and cook for another minute until fragrant.
- Step 6: Add the sliced mushrooms to the skillet. Cook, stirring occasionally, until the mushrooms release their liquid and it mostly evaporates, and they start to brown, about 8-10 minutes. Season with a pinch of salt and pepper. Remove from heat and set aside to cool slightly.
- Step 7: In a large mixing bowl, combine the ricotta cheese, the thoroughly squeezed and chopped spinach, the large egg, ½ cup of grated Parmesan cheese, 1 teaspoon of Italian seasoning, a generous pinch of nutmeg, and salt and black pepper to taste. Mix well until everything is thoroughly combined.
- Step 8: Spread a thin layer (about ½ cup) of marinara sauce on the bottom of a 9×13 inch baking dish.
- Step 9: Arrange a single layer of lasagna noodles over the sauce. If using oven-ready noodles, make sure they don’t overlap too much. Break them if necessary to fit the dish.
- Step 10: Evenly spread half of the ricotta-spinach mixture over the noodles.
- Step 11: Spoon half of the cooked mushroom mixture over the ricotta layer.
- Step 12: Sprinkle about 1 cup of shredded mozzarella cheese over the mushrooms.
- Step 13: Top with another layer of noodles.
- Step 14: Spread another layer of marinara sauce (about 1 cup) over the noodles.
- Step 15: Repeat the ricotta-spinach, mushroom, and mozzarella layers.
- Step 16: Place the final layer of noodles on top.
- Step 17: Spread the remaining marinara sauce (about 1.5 – 2 cups) over these noodles, ensuring they are well covered.
- Step 18: Finish by sprinkling the remaining mozzarella cheese and ¼ cup of Parmesan cheese over the top.
- Step 19: Cover the baking dish tightly with aluminum foil.
- Step 20: Bake for 45 minutes.
- Step 21: Remove the foil and bake for another 15-20 minutes, or until the cheese is bubbly and golden brown.
- Step 22: Once out of the oven, let the lasagna rest for at least 15-20 minutes before slicing and serving.
