• Fresh Garlic – Enhances flavor; approximately 4-6 cloves minced.
• All-Purpose Flour – Used to create the roux, essential for thickening the béchamel.

• Grated Parmesan Cheese – Introduces a sharp, savory depth to the sauce.
• Kosher Salt & Black Pepper – Essential for seasoning; adjust to taste.
• Ground Nutmeg – Provides warmth and enhances the flavor profile.
For the Filling
• Olive Oil – Used for sautéing vegetables; can substitute with butter.
• Baby Bella Mushrooms – Adds an earthy flavor; can substitute with button mushrooms.
• Fresh Baby Spinach – Contributes vibrant color and nutrients; can swap for kale if preferred.
• Whole Milk Ricotta Cheese – Forms the creamy filling; consider using part-skim for a lighter option.
• Large Eggs – Binds the cheese mixture; omit for a completely dairy-free version.
For Assembly

Step‑by‑Step Instructions for White Lasagna with Spinach and Mushrooms
Step 1: Make the Roux
In a medium saucepan over medium heat, melt 4 tablespoons of unsalted butter until foamy. Add 4–6 minced garlic cloves and sauté for about 1 minute until fragrant. Stir in 1/4 cup of all-purpose flour and continue cooking for an additional minute until toasted, creating a roux with a light golden color.
Step 2: Prepare the Sauce
Gradually whisk in 2 cups of half and half and 1 cup of whole milk, stirring continuously to avoid lumps. Keep the mixture on the heat for 2–3 minutes, or until it thickens to a creamy consistency. Once thickened, mix in 1 cup of grated Parmesan cheese, along with kosher salt, black pepper, and a pinch of ground nutmeg. Set this creamy béchamel sauce aside.
Step 3: Cook the Vegetables
Heat 2 tablespoons of olive oil in a large skillet over medium-high heat. Add sliced baby Bella mushrooms, sautéing for about 3–4 minutes until they are tender and golden brown. Toss in the baby spinach and minced garlic, stirring until the spinach wilts, which should take about another 2–3 minutes. Allow the mixture to cool slightly.
Step 4: Prepare Cheese Filling
In a mixing bowl, combine 15 ounces of whole milk ricotta cheese, 1/2 cup of grated Parmesan, 1 large egg, and a sprinkle of salt and pepper. Gently fold in the cooled mushroom and spinach mixture, creating a rich, flavorful filling for your white lasagna with spinach and mushrooms.
Step 5: Assemble the Lasagna
Preheat your oven to 375°F (190°C). In a greased 9×13-inch baking dish, spread a thin layer of the béchamel sauce on the bottom. Layer over 3–4 oven-ready lasagna noodles, followed by half of the ricotta mixture, and a layer of shredded mozzarella cheese. Repeat these layers, finishing with the béchamel sauce and a generous topping of mozzarella.
Step 6: Bake
Cover the lasagna with foil and bake in the preheated oven for 50 minutes. After 50 minutes, remove the foil and bake for an additional 10 minutes, or until the top is golden and bubbly. Let the white lasagna with spinach and mushrooms rest for 15 minutes before slicing to allow the flavors to meld beautifully.
