• 1 teaspoon dried basil
• 1/2 teaspoon salt
• 1/4 teaspoon black pepper
• 1/4 cup dry white wine (optional)

For the Creamy Cheese Sauce:

• 15 ounces whole milk ricotta cheese
• 1 large egg
• 1/2 cup grated Parmesan cheese
• 2 tablespoons fresh parsley, chopped
• 1 teaspoon garlic powder
• 1/2 teaspoon salt

For Assembly:

• 12 lasagna noodles, cooked according to package directions
• 3 cups shredded mozzarella cheese, divided
• 1/2 cup additional Parmesan cheese for topping
• 2 tablespoons fresh basil leaves for garnish

Step-by-Step Instructions

Step 1: Prepare the Pasta

Cook the lasagna noodles according to package directions until al dente. Drain and set aside. To prevent sticking, you can drizzle a little olive oil over the cooked noodles.

Step 2: Create the Mushroom-Spinach Filling

1. Heat olive oil in a large skillet over medium-high heat.
2. Add diced onion and cook for 3-4 minutes until softened.
3. Add minced garlic and cook for another minute until fragrant.
4. Add sliced mushrooms to the pan and cook for 8-10 minutes, stirring occasionally, until they release their moisture and become golden brown.
5. If using wine, add it now and let it cook for 2 minutes to evaporate.
6. Add fresh spinach leaves (or drained frozen spinach) and cook until wilted, about 2-3 minutes.
7. Season with oregano, basil, salt, and pepper. Remove from heat and set aside.

Step 3: Make the Creamy Cheese Mixture

In a large bowl, combine ricotta cheese, egg, Parmesan cheese, chopped parsley, garlic powder, salt, and nutmeg. Mix until smooth and well combined.

Step 4: Assemble the Lasagna

1. Preheat your oven to 375°F (190°C).
2. Spread a thin layer of the ricotta mixture on the bottom of your 9×13 inch baking dish.
3. Place 4 lasagna noodles over the ricotta layer.
4. Spread half of the remaining ricotta mixture over the noodles.
5. Add half of the mushroom-spinach mixture.
6. Sprinkle 1 cup of mozzarella cheese over the vegetables.
7. Repeat layers: 4 more noodles, remaining ricotta mixture, remaining mushroom-spinach mixture, and another cup of mozzarella.
8. Top with the final 4 noodles, remaining mozzarella, and additional Parmesan cheese.

Step 5: Bake to Perfection

1. Cover tightly with aluminum foil and bake for 25 minutes.
2. Remove foil and bake for an additional 15-20 minutes until the cheese is bubbly and lightly golden.
3. Let the lasagna rest for 10-15 minutes before serving to allow it to set properly.

Pro Tips for Perfect Lasagna

Don’t Skip the Resting Time: Allowing your lasagna to rest after baking is crucial. This helps the layers set and makes serving much easier.

Mushroom Preparation: Make sure to cook your mushrooms until most of their moisture has evaporated. This prevents your lasagna from becoming watery.

Spinach Drainage: If using frozen spinach, squeeze out as much liquid as possible to avoid soggy layers.

Cheese Distribution: Save some of the best cheese for the top layer to get that beautiful golden-brown finish.

Make-Ahead and Storage Tips

This creamy spinach mushroom lasagna is perfect for meal prep! You can assemble it completely and refrigerate for up to 2 days before baking. If baking from cold, add an extra 10-15 minutes to the cooking time.

Freezing Instructions: Wrap the assembled (unbaked) lasagna tightly in plastic wrap and aluminum foil. Freeze for up to 3 months. Thaw overnight in the refrigerator before baking.

Leftover Storage: Store leftover lasagna in the refrigerator for up to 4 days. Reheat individual portions in the microwave or reheat the whole dish covered in a 350°F oven.

Variations and Substitutions

Vegan Option: Replace ricotta with cashew cream, use nutritional yeast instead of Parmesan, and dairy-free mozzarella.

Gluten-Free: Use gluten-free lasagna noodles or substitute with thinly sliced zucchini or eggplant.

Additional Vegetables: Try adding roasted bell peppers, sun-dried tomatoes, or artichoke hearts for extra flavor.

Herb Variations: Fresh thyme, sage, or rosemary can add different flavor profiles to your mushroom mixture.
