Step‑by‑Step Instructions for Creamy White Chicken Lasagna with Spinach and Mushrooms
Step 1: Sauté Vegetables
In a large skillet, heat 2 tablespoons of oil over medium-high heat. Add 1 diced onion, 2 minced garlic cloves, and 8 ounces of sliced white mushrooms. Sauté for about 5 minutes until the onions are translucent and mushrooms are tender. Stir in 4 cups of fresh spinach and cook until wilted, about 2 minutes. Add 2 cups of shredded cooked chicken, mixing well before setting aside.
Step 2: Prepare Sauce
In a medium saucepan, combine 2 cups of chicken stock, 2 cups of milk, a pinch of nutmeg, and salt to taste. Bring this mixture to a gentle simmer over medium heat. Gradually whisk in a slurry made from ¼ cup of all-purpose flour mixed with ½ cup of water, stirring continuously until thickened, about 5 minutes. Remove from heat and fold in 1 cup of grated Parmesan cheese until creamy.
Step 3: Layer Lasagna
Preheat your oven to 375°F (190°C). In a 9×13-inch baking dish, pour half of the prepared sauce on the bottom. Arrange a layer of no-boil lasagna noodles over the sauce, followed by half of the chicken and vegetable mixture. Pour more sauce over this layer, then sprinkle 2 cups of shredded mozzarella cheese on top. Repeat the layering process once more, finishing with noodles and remaining white sauce.
Step 4: Bake
Cover the baking dish tightly with aluminum foil, ensuring it doesn’t touch the cheese. Bake in the preheated oven for 25 minutes. Uncover the dish and bake for an additional 15 minutes, or until the cheese is bubbly and lightly golden on top. Keep an eye on the edges to ensure they don’t over-brown.
Step 5: Rest and Serve
Once out of the oven, let the creamy White Chicken Lasagna rest for about 15-20 minutes. This resting time allows the layers to set, making it easier to slice. When ready, cut into squares and serve warm, garnishing with extra Parmesan or a sprinkle of chopped herbs if desired.
