• Milk – Creates a creamy sauce; can use whole milk or a non-dairy alternative for richness.

Step‑by‑Step Instructions for Creamy White Chicken Lasagna with Spinach & Mushroom
Step 1: Sauté the Vegetables
In a large skillet, heat a drizzle of olive oil over medium heat. Add finely chopped onions and minced garlic, sautéing for 2-3 minutes until fragrant and translucent. Stir in sliced white mushrooms along with dried basil, oregano, and red pepper flakes. Cook for an additional 5-7 minutes until the mushrooms are soft. Finally, add fresh spinach and stir until wilted, then mix in the shredded cooked chicken, incorporating everything evenly.
Step 2: Prepare the White Sauce
In a saucepan, combine 2 cups of chicken stock and 1 cup of milk over medium heat. Gradually whisk in a slurry of ¼ cup all-purpose flour mixed with a bit of cold chicken stock until smooth. Bring the mixture to a gentle simmer while continuously stirring for about 5-7 minutes, allowing it to thicken. Once thickened, remove from heat and stir in ¾ cup grated Parmesan cheese until melted and creamy; this will be the luscious sauce for your lasagna.
Step 3: Assemble the Lasagna
In a 9×13-inch baking dish, spread half of the creamy white sauce on the bottom. Layer in 3 no-boil lasagna noodles, ensuring they are evenly spaced. Spoon half of the spinach and chicken mixture over the noodles, followed by one-third of the remaining sauce. Sprinkle a generous layer of 1 cup of shredded mozzarella cheese on top. Repeat this layering process once more, ending with the last 3 noodles, remaining sauce, and the last cup of mozzarella to create a delicious topping.
Step 4: Bake the Lasagna
Preheat your oven to 375°F (190°C). Cover the assembled lasagna with aluminum foil to prevent drying out, and place it in the preheated oven. Bake for 25 minutes, then carefully remove the foil and bake for an additional 15 minutes or until the cheese on top is bubbly and golden brown. The edges should be slightly crispy, indicating that your creamy white chicken lasagna is ready to come out of the oven.
Step 5: Let it Rest
Once your lasagna is out of the oven, allow it to rest for 15-20 minutes before slicing. This resting period lets the layers firm up and makes serving easier, ensuring you get beautifully cut pieces. Trust me, this step is essential for a satisfying bite that showcases all those lovely creamy layers packed with flavor in your white chicken lasagna!

How to Store and Freeze White Chicken Lasagna
Fridge: Store leftovers in an airtight container for up to 4 days to keep your creamy lasagna fresh and delicious.
Freezer: Wrap individual portions securely in plastic wrap or aluminum foil and place them in a freezer-safe container. Enjoy your white chicken lasagna for up to 3 months.
Reheating: Thaw overnight in the fridge before reheating. Heat in the oven at 350°F for about 20-25 minutes until warmed through, or microwave for a quick option.
Layering: When freezing, consider separating layers with parchment paper to make it easier to reheat individual servings.

White Chicken Lasagna with Spinach & Mushroom Recipe FAQs
How do I choose the best spinach for the lasagna?
Absolutely! When selecting spinach, look for vibrant green leaves without any dark spots or wilting. Fresh spinach has a crisp texture and a slightly sweet taste, which will enhance your lasagna. If using frozen spinach, ensure it’s thawed and thoroughly drained to remove excess water, preventing a soggy dish.
What’s the best way to store leftover creamy white chicken lasagna?
Very! Store leftovers in an airtight container in the fridge for up to 4 days to maintain their creamy goodness. If you plan to keep it longer, freeze portions by wrapping them tightly in plastic wrap or aluminum foil and placing them in a freezer-safe container. This way, your lasagna can be enjoyed for up to 3 months!
Can I freeze white chicken lasagna, and how do I do it?
Certainly! To freeze your white chicken lasagna, first, let it cool to room temperature. Then, slice it into individual portions for easy reheating. Wrap each piece securely in plastic wrap or aluminum foil, and place them in a freezer-safe container. For optimal flavor, I recommend adding a layer of parchment paper between portions, making it easier to reheat later without sticking.
How can I prevent my lasagna from being watery?
Great question! To ensure a satisfying texture, make sure to thoroughly sauté the mushrooms and spinach until all moisture is released before layering them in your lasagna. Additionally, using no-boil noodles helps absorb some moisture during cooking, but it’s vital to layer generously with sauce and chicken. Lastly, allow the lasagna to rest for 15-20 minutes after baking, which will help the layers firm up for cleaner slices and a more appealing presentation.
Are there any dietary considerations related to this recipe?
Absolutely! If you’re hosting someone with dietary restrictions, it’s easy to adapt this recipe. For a gluten-free version, substitute all-purpose flour with cornstarch for the white sauce and ensure your noodles are gluten-free. Additionally, for those who prefer a vegetarian option, simply omit the chicken and load up on extra vegetables like zucchini or bell peppers to make a delicious, veggie-packed dish!
