The Ultimate Creamy Chicken, Mushroom & Spinach Lasagna: A Cheesy White Sauce Delight for Any Occasion
This Chicken, Mushroom, and Spinach Lasagna with a luxurious cheesy white sauce isn’t just a meal; it’s an elevated experience. It’s the ingenious twist on the classic comfort food you’ve been eagerly seeking, transforming traditional lasagna into something fresh, vibrant, and utterly delicious. Forget the familiar red sauce for a moment and prepare to be enchanted by layers of tender chicken, earthy sautéed mushrooms, and wholesome spinach, all generously enveloped in a rich, creamy, and undeniably cheesy béchamel sauce.
Why Chicken, Mushroom, and Spinach Lasagna is Your Go-To for Effortless Entertaining
When it comes to hosting friends or family, lasagna consistently tops my list of ideal main courses. It’s truly a secret weapon for entertaining, offering a perfect blend of elegance and practicality. The biggest win for me? This hearty dish can be almost entirely prepped ahead of time, freeing you from kitchen duties when your guests arrive. Imagine: your lasagna is nestled in the oven, filling your home with an inviting aroma, while you relax, sip a glass of wine, and genuinely connect with your friends. No one is stuck tending to pots and pans on the stove, allowing everyone, including the host, to enjoy the evening to its fullest. This kind of hands-off cooking during a party is, in my opinion, a huge success.
I find immense joy in reinventing classic recipes, always searching for innovative ways to make them feel new and exciting. While it’s certainly challenging to surpass the original, time-honored lasagna with its robust tomato sauce and generous layers of cheese, that doesn’t deter me from exploring new interpretations. My family also adores this delightful butternut squash version, which offers a wonderful autumnal flavor. However, I’ve long felt the need to add one more versatile variation to my culinary repertoire, something distinctly different and equally impressive for those special dinner parties and gatherings. This chicken, mushroom, and spinach lasagna with its divine white sauce has perfectly filled that delicious void.
A Symphony of Flavors: What Makes This Lasagna Special
This particular lasagna stands out with its meticulously crafted layers. It features succulent shredded chicken, infused with aromatic garlic and sautéed with tender mushrooms and fresh spinach. This savory filling is beautifully complemented by a velvety, cheesy white sauce, which binds everything together with its creamy texture and rich flavor. Generous amounts of mozzarella cheese add to the decadent gooeyness, while oven-ready lasagna noodles simplify the assembly process, cutting down on prep time significantly. The result is a dish that is wonderfully creamy, incredibly cheesy, and provides an unparalleled sense of comforting warmth with every bite. It’s a complete meal that feels both wholesome and indulgent, perfect for warming up a chilly evening or celebrating a special occasion.
Key Ingredients for a Perfectly Creamy Lasagna
The magic of this Chicken, Mushroom, and Spinach Lasagna lies in the harmony of its simple yet high-quality ingredients. Each component plays a vital role in creating its rich flavor and comforting texture. Let’s delve into what makes each ingredient essential:
- Shredded Cooked Chicken: The foundation of our savory filling. You can easily use leftover rotisserie chicken for ultimate convenience, or quickly boil and shred chicken breasts. The tender chicken provides a satisfying protein element that makes this lasagna a hearty meal.
- Garlicky Mushrooms: Sliced mushrooms, such as cremini or button, add an incredible depth of earthy, umami flavor. Sautéing them with garlic until they are golden and slightly caramelized unlocks their full potential, creating a rich base for the filling.
- Fresh Spinach: This vibrant green vegetable not only adds a touch of color and nutrients but also wilts down beautifully into the filling, balancing the richness of the cheese and chicken with its fresh, slightly bitter notes. Using fresh spinach is preferred for its texture, but frozen (thawed and squeezed dry) works too.
- Cheesy White Sauce (Béchamel): This is the heart of our creamy lasagna. Made with butter, flour, milk, and generously seasoned with Parmesan cheese, coarse salt, black pepper, and a hint of freshly grated nutmeg, this sauce creates an incredibly smooth, rich, and flavorful binding agent for all the layers. The nutmeg is crucial here, providing that classic, warm, and sophisticated flavor profile often associated with creamy sauces.
- Whole Milk Ricotta Cheese: Blended into the white sauce, ricotta adds another layer of creamy texture and a subtle tang, characteristic of a well-made Italian lasagna. Using whole milk ricotta ensures maximum creaminess and flavor.
- Mozzarella Cheese: What’s lasagna without gooey, melted cheese? Shredded mozzarella provides that irresistible stretchy texture and mild, milky flavor that perfectly complements the other ingredients, creating beautiful, comforting layers.
- Oven-Ready Lasagna Noodles: A game-changer for reducing prep time! These noodles eliminate the need for pre-boiling, making the assembly process quicker and cleaner. However, traditional noodles can certainly be used if you prefer, just follow their package instructions.
Make This Part of Your Next Dinner Party Menu
While this chicken, mushroom, and spinach lasagna is wonderfully adaptable for any occasion, from a casual weeknight dinner to a festive holiday meal, it truly shines as the centerpiece of a dinner party. Here are a few invaluable tips to ensure it becomes the star of your next gathering and keeps you relaxed while entertaining:
- Master the Art of Make-Ahead: The beauty of lasagna lies in its ability to be prepped in advance. Assemble the entire lasagna earlier in the day, or even the day before, cover it tightly with foil, and store it in the refrigerator. This significantly reduces stress on the day of your event, allowing you to simply pop it into the oven when your guests are about to arrive. This forethought is a game-changer for any host.
- Presentation Matters: Elevate the dining experience by using your prettiest ceramic or glass casserole dish. A beautiful baking vessel means you can take the lasagna straight from the oven to the table, serving it family-style. This approach is not only charming but also encourages conversation and a relaxed atmosphere around the table.
- The Golden Rule of Resting: This step is non-negotiable for perfectly sliceable lasagna. Be sure to plan for the lasagna to rest for approximately 15 minutes after it comes out of the oven, uncovered. This crucial resting period allows all the different cheeses and fillings to set properly. The result? Clean, stable, and beautifully defined slices that hold their shape on the plate. Don’t worry, it will still be wonderfully hot and ready to enjoy!
- Effortless Side Dishes: For truly easy entertaining, pair your rich lasagna with simple, complementary sides. A store-bought artisan baguette or a crusty loaf of bread, perhaps warmed and served with garlic butter, is perfect for soaking up any extra sauce. A crisp green salad, tossed with a light vinaigrette just before everyone sits down to eat, offers a refreshing contrast. If you’d like one more side, consider roasting easy vegetables like asparagus or green beans in the oven while the lasagna is resting. This adds another layer of flavor and texture without much extra effort.
- Delightful Make-Ahead Desserts: After indulging in such a satisfying and comforting lasagna, your guests will likely be quite full. Therefore, there’s no need to fuss over an overly elaborate dessert. Opt for something simple yet elegant that can also be prepared ahead of time. My personal favorites that pair wonderfully and keep the relaxed vibe going include this light and fragrant lemon olive oil cake, refreshing and creamy strawberry chocolate parfaits, or delightful and easy chocolate hazelnut cookies. These sweet endings provide a perfect, relaxed conclusion to your meal.
Tips & Customization for Your Perfect Lasagna
Beyond the core recipe, a few extra tips can help you achieve lasagna perfection and even customize it to your liking:
- Spinach Prep: If you opt for frozen spinach, ensure it’s fully thawed and squeeze out *all* excess moisture. This prevents a watery lasagna and ensures the flavors remain concentrated.
- Noodle Choice: While I highly recommend no-boil, oven-ready lasagna noodles for their convenience, don’t hesitate to use traditional lasagna noodles if that’s what you have on hand or prefer. Just make sure to prepare them according to the package instructions before assembling your lasagna.
- Advance Preparation & Freezing: This lasagna is an excellent candidate for meal prep.
- Chilling: Assemble the lasagna completely, cover it tightly with aluminum foil, and store it in the fridge for up to 24 hours before baking. When ready to bake, you might need to add an extra 10-15 minutes to the covered baking time if it’s straight from the cold fridge.
- Freezing: For longer storage, assemble the lasagna, then double-wrap it securely in plastic wrap and then foil. It can be frozen for a month or even longer. To bake from frozen, simply remove the plastic wrap, keep it covered with foil, and add approximately 15-20 minutes to the initial covered baking time. You’ll know it’s ready when it’s bubbling through the layers.
- Personalize Your Lasagna: Feel free to experiment with different herbs like thyme or sage in the white sauce, or add a pinch of red pepper flakes for a subtle kick. You could also try different combinations of cheeses, such as a sharp cheddar or provolone for added depth. A sprinkle of fresh parsley or chives at the end can also enhance the aroma and presentation.

Ingredients
- 4 tablespoons butter (56 grams), divided
- 8 ounces mushrooms (227 grams), sliced
- Salt and pepper , to taste
- 8 ounces spinach (1 medium bunch)
- 2 cloves garlic , minced
- 2 cups shredded cooked chicken (300 grams)
- 2 tablespoons all-purpose flour
- 2 cups milk (500 ml)
- 15 oz whole milk ricotta cheese (425 grams)
- 1 cup shredded Parmesan cheese (100 grams), divided
- 1 teaspoon coarse salt
- ½ teaspoon ground black pepper
- ½ teaspoon freshly grated nutmeg
- 8 ounces lasagna noodles (227 grams), I used no-boil, oven-ready
- 8 ounces mozzarella cheese (227 grams), shredded
- Chopped basil ,for garnish
Instructions
-
Preheat your oven to 350 degrees F (175 degrees C). Take a 9×13-inch or similarly sized casserole dish and lightly grease it. This step helps prevent sticking and ensures easy serving.
-
In a large skillet, melt 2 tablespoons of the butter over medium heat. Add the sliced mushrooms and season them generously with salt and pepper. Cook, stirring occasionally, until the mushrooms have softened and released their moisture, which typically takes about 5 minutes. Next, add the fresh spinach and minced garlic to the skillet. Continue to cook for another 1-2 minutes, stirring frequently, until the spinach is completely wilted. Transfer this aromatic mushroom and spinach mixture to a large bowl and gently fold in the shredded cooked chicken. Set aside.
-
Return the same skillet to the heat and melt the remaining 2 tablespoons of butter. Once melted, add the all-purpose flour and stir continuously for about 1 minute to create a roux. Gradually pour in the milk, whisking constantly to ensure there are no lumps and the mixture is smooth. Bring the sauce to a gentle boil, then reduce the heat and continue to cook, whisking, until it has thickened to your desired consistency – usually a creamy, pourable sauce.
-
Reduce the heat to low. Stir in the whole milk ricotta cheese, 1/2 cup of the shredded Parmesan cheese, a generous pinch of salt and pepper, and the freshly grated nutmeg. Continue to stir until the sauce is completely smooth and all the cheeses are well incorporated. This forms your rich and creamy white sauce base.
-
Now, it’s time to assemble your delicious lasagna! Spread a thin spoonful of the prepared white sauce onto the bottom of your greased casserole dish. This prevents the first layer of noodles from sticking. Arrange a layer of lasagna noodles over the sauce, gently breaking them to fit the dish as necessary (especially if using no-boil noodles). Spoon more of the creamy white sauce evenly over the noodles, followed by 1/3 of the chicken, mushroom, and spinach mixture. Sprinkle with 1/4 of the shredded mozzarella cheese. Repeat these layers two more times, ensuring each layer is evenly distributed. For the final top layer, spread the remaining white sauce, then sprinkle generously with the rest of the mozzarella cheese, and finally, the remaining 1/2 cup of Parmesan cheese for a golden, cheesy crust.
-
Cover the casserole dish tightly with aluminum foil and bake in the preheated oven for 35 minutes. After this time, carefully remove the foil and continue baking uncovered for another 10-15 minutes, or until the cheese on top is beautifully melted, bubbly, and lightly browned to perfection.
-
Once baked, remove the lasagna from the oven and let it sit undisturbed for about 15 minutes before serving. This resting period is crucial as it allows the layers to set, making for cleaner, more stable slices. Garnish with fresh chopped basil if desired, then slice, serve, and savor every comforting bite!
Notes
- You can definitely use frozen spinach as a convenient alternative. Just be sure to thaw it completely and squeeze out all excess moisture before adding it to the mushroom mixture. This prevents the lasagna from becoming watery.
- I prefer using no-boil, oven-ready lasagna noodles to significantly cut down on prep work, making the recipe faster and easier. However, if you prefer traditional lasagna noodles, feel free to use them. Just make sure to prepare them according to the package instructions (usually boiling them first) before assembling your lasagna.
- This chicken, mushroom, and spinach lasagna is an excellent make-ahead dish, perfect for busy weeknights or entertaining:
- Assemble and Chill: You can fully assemble the lasagna, cover it tightly, and chill it in the refrigerator for up to 24 hours before baking. Simply take it out of the fridge about 30 minutes before baking to let it come closer to room temperature, and potentially add an extra 10-15 minutes to the initial covered baking time.
- Assemble and Freeze: For longer storage, assemble the lasagna as directed, then double-wrap it securely first in plastic wrap and then in aluminum foil. It can be safely frozen for a month or even longer. When you’re ready to enjoy, bake it directly from frozen, adding approximately 15-20 minutes to the covered baking time until it’s heated through and bubbling.
