- Yield: 8 servings
Description
Creamy, comforting, and easy to assemble, this Chicken Alfredo Lasagna Casserole combines tender chicken, savory mushrooms, and rich Alfredo sauce between cheesy layers — all baked into a bubbling, golden casserole that’s gluten-free and crowd-pleasing.
Ingredients
1 pound mushrooms, chopped
1 tablespoon plus 2 teaspoons olive oil
8 cups cooked chicken, diced
1 small onion, chopped
2 teaspoons poultry seasoning
2 teaspoons garlic powder
1 teaspoon dried sage, or to taste
15 ounces prepared Alfredo-style sauce
4 large Parmesan-style cheese wraps or slices, cut in half
3 cups shredded mozzarella cheese
Instructions
1. Preheat the oven to 375°F.
2. If not already prepared, dice the cooked chicken into bite-size pieces and set aside.
3. Heat 1 tablespoon of the olive oil in a large skillet over medium heat. Add the mushrooms and cook, stirring occasionally, until they are well browned and any liquid has evaporated. Transfer mushrooms to a plate.
4. Add the remaining olive oil to the skillet, then stir in the chopped onion. Cook for about 3 minutes, until softened.

7. Pour in the Alfredo-style sauce, reduce heat to low, and let the mixture simmer for about 10 minutes, stirring occasionally, until slightly thickened.
8. Lightly grease a medium casserole dish. Arrange a single layer of the Parmesan-style wraps over the bottom of the dish.
9. Spread half of the chicken and mushroom mixture evenly over the wraps. Sprinkle with 1½ cups of mozzarella cheese.
10. Add a second layer of wraps, followed by the remaining chicken mixture and the remaining mozzarella cheese.
11. Bake uncovered for 30 to 35 minutes, until the casserole is bubbling and the top is lightly golden.
12. Let rest for about 10 minutes before slicing and serving for best texture.
Notes
You can substitute rotisserie chicken for faster prep. To add greens, sauté spinach with the onions before layering. This casserole can be made a day ahead and baked fresh before serving.

Why Chicken Alfredo Lasagna Casserole is the Ultimate Comfort Food
The magic of this Chicken Alfredo Lasagna Casserole is how it transforms a handful of everyday ingredients into something that feels utterly luxurious. It borrows the richness of traditional Alfredo pasta, infuses it with the structure of lasagna, and simplifies everything by making it a single-layered, no-boil bake. It’s that creamy-meets-savory blend that hits all the right notes — from the first bite to the last.
There’s something about casseroles that evoke a kind of nostalgia. They remind us of family dinners, of food that was made with love and intended to be shared. This casserole does all of that, but with an elevated flavor profile thanks to the earthy mushrooms, aromatic sage, and poultry seasoning. Whether you’re making it for a cozy night in or meal prepping for the week ahead, it never fails to satisfy.
Part of its appeal is the melt-in-your-mouth texture. The Alfredo sauce wraps around each chunk of chicken and mushroom, clinging to every crevice in the Parmesan wrap layers. The top, golden and bubbling, delivers that oven-baked crispness we all crave — creating a perfect contrast to the creamy layers underneath.
Ingredients That Make This Chicken Alfredo Lasagna Casserole Irresistible
At the heart of this recipe is a brilliant combination of texture and flavor. The mushrooms, sautéed until golden brown, bring a deep umami flavor that adds serious depth to the dish. When cooked properly, they release all their moisture and concentrate in flavor, ensuring they don’t water down the Alfredo sauce later.
Then there’s the chicken — tender, juicy, and versatile. Whether you use leftover roasted chicken, store-bought rotisserie, or prepare it fresh, it becomes the hearty anchor of this casserole. When paired with sage and garlic powder, it takes on a homey, herbal warmth that balances out the richness of the cream sauce.
But perhaps the most unexpected hero is the use of Parmesan-style cheese wraps in place of traditional lasagna noodles. Not only do they make this dish gluten-free, but they also contribute a nutty, salty backdrop that enhances every bite. Layered with a generous amount of shredded mozzarella, it all melts together into a beautifully cohesive casserole that feels both indulgent and comforting.
Step-by-Step Cooking Method for Perfect Results
Great casseroles start with a solid flavor base, and this one begins in a skillet. First, you’ll want to give the mushrooms the attention they deserve — cooking them until their edges caramelize and all their liquid has evaporated. It’s a small step that pays off big in flavor.
Once those are set aside, sautéing the onions in the same pan allows you to build on that flavor. A few spices — poultry seasoning, garlic powder, and dried sage — are added at just the right moment to bloom in the hot oil, releasing their aromas before the chicken and mushrooms are folded back in. Then comes the Alfredo sauce, stirred in and allowed to simmer until slightly thickened, blending all the ingredients into one velvety mixture.
Assembling the casserole is as easy as layering. You start by greasing your dish, then laying down the first layer of Parmesan wraps. Half the creamy chicken mixture is spread over them, followed by a thick sprinkle of mozzarella. Then the layering is repeated, finishing with a final blanket of cheese.
Once it’s baked, the casserole emerges golden and bubbling, with crispy edges and an aroma that fills your entire kitchen. Letting it rest before slicing is key — it allows the layers to set, giving you perfect slices that hold together beautifully.
Tips and Tricks for the Best Chicken Alfredo Lasagna Casserole Every Time
If you’re looking to make this casserole even more efficient for busy nights, consider prepping your ingredients ahead of time. You can sauté the mushrooms and onions, dice the chicken, and even assemble the entire dish the night before. Just cover and refrigerate it, then pop it in the oven when ready to bake.
Avoiding a watery casserole is all about cooking off excess moisture in the early steps. Make sure the mushrooms are browned and dry before adding them back in with the sauce, and always let your Alfredo mixture simmer long enough to thicken slightly before layering.
Using leftover rotisserie chicken is not only convenient but incredibly flavorful. It’s a great way to minimize prep while maximizing taste. And if you’re looking to make a double batch, this casserole freezes well too — just be sure to wrap it tightly and label it.

Variations to Keep Your Chicken Alfredo Lasagna Casserole Fresh
If you’re in the mood to experiment, there are endless ways to customize this casserole. Adding fresh spinach or kale to the layers gives it a pop of color and a welcome nutritional boost. Just make sure to sauté any greens before layering to remove excess moisture.
Want to add a little heat? A sprinkle of crushed red pepper or a dash of cayenne in the Alfredo sauce will liven up the flavor without overpowering it. You could also swap in spicy Italian sausage for the chicken if you’re after something a bit bolder.
For those following a low-carb or keto lifestyle, you’re already off to a great start with the cheese wraps instead of pasta. To take it even further, you can use a homemade Alfredo sauce made with heavy cream and Parmesan for more control over the macros.

Serving Suggestions and What to Pair With Chicken Alfredo Lasagna Casserole
This casserole is rich and satisfying on its own, but a few simple sides can round out the meal beautifully. A crisp green salad with a bright vinaigrette cuts through the richness and adds freshness to the plate. Roasted asparagus or steamed green beans make excellent companions as well.
If you’re serving it for guests or a holiday meal, a loaf of garlic bread or low-carb rolls on the side turns it into a feast. And for something to sip, a glass of chilled Chardonnay or sparkling water with lemon adds just the right contrast.
Leftovers store beautifully, and reheating is simple — just cover and warm in the oven at 350°F until heated through. You can also reheat individual slices in the microwave with great results.
