Three-Cheese Creamy Lasagna (Print Version)

# Ingredients:

→ Base Layer

01 - 12 wide lasagna sheets, classic or a gluten-free pick you love

→ Hearty Vegetable Filling

02 - 10 ounces of fresh leafy spinach (or a frozen pack, thawed and squeezed dry)
03 - 2 tablespoons of rich olive oil
04 - 16 ounces of sliced mushrooms (a mix of button and cremini is great)
05 - 3 cloves of garlic, finely chopped
06 - 1 small onion, diced into small bits

→ Velvety White Sauce

07 - 4 tablespoons of smooth unsalted butter
08 - A generous pinch of both sea salt and ground black pepper
09 - 1/4 cup of plain flour (gluten-free blends work too)
10 - 1/2 teaspoon of ground nutmeg, for a warm touch
11 - 3 cups of whole milk to make it creamy

→ Cheese Blend

12 - 1 large egg, lightly whisked
13 - 2 cups of freshly shredded mozzarella
14 - 1/2 cup of freshly grated Parmesan cheese
15 - 1 1/2 cups of creamy ricotta

# Instructions:

01 - Fill a big pot with water, bring it to a bubbling boil, and toss in some salt. Cook your noodles until just soft but not mushy. Drain them and spread flat so they don't stick.
02 - Heat olive oil in a large pan. Add chopped onions and cook for a few minutes until clear and soft. Stir in your garlic and let it get fragrant for a minute. Toss in your mushrooms and cook until they're golden brown and their liquid is gone, about 8 minutes. Finally, wilt the spinach down in the pan and season with pepper and salt to your liking.
03 - In a medium saucepan, melt butter over medium heat. Mix in your flour and stir constantly for about a minute until golden and fragrant. Slowly pour in the milk and whisk like crazy to avoid lumps. Cook until thickened, about 5-7 minutes. Add a sprinkle of nutmeg, salt, and pepper at the end.
04 - In a bowl, mix the ricotta, egg, and half a cup of mozzarella. Add just a bit of salt to enhance the flavor.
05 - Set your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish. Spread a thin layer of white sauce on the bottom, then lay down your first layer of pasta sheets. Add 1/3 of the ricotta mix and then half the spinach-mushroom mix. Repeat the layers and finish with noodles, the remaining sauce, and a top layer of both mozzarella and Parmesan.
06 - Cover the dish with foil and bake for 25 minutes. Then, remove the foil and bake another 15-20 minutes until the top turns golden brown and the edges bubble. Let it rest for 10 minutes before cutting into it.

# Notes:

01 - You can prepare this dish up to a day in advance and refrigerate it, covered, until baking time.
02 - Store leftovers in an airtight container in the fridge; they stay good for 5 days.
03 - Play around with mushroom types to switch things up a bit.
