What to Buy for Chicken Alfredo Lasagna Casserole

When it comes to the ingredients for Chicken Alfredo Lasagna Casserole, simplicity is key. Each ingredient plays a significant role in bringing the flavors together harmoniously. You’ll find that mushrooms add an earthy depth, while the creamy Alfredo sauce ties everything into a rich, comforting dish.
- 1 lb. mushrooms, chopped into medium-size pieces: Fresh mushrooms add a savory, umami flavor that complements the dish beautifully.
- 1 T + 2 tsp. olive oil: This is used to sauté your mushrooms and onions, adding a rich taste to the base of the casserole.
- 8 cups diced, cooked chicken: A great source of protein and the star of the dish, providing heartiness.
- 1 small onion, chopped: Onions add a subtle sweetness and depth of flavor when sautéed.
- 2 tsp. Poultry Seasoning: This blend enhances the chicken’s flavor, making it savory and aromatic.
- 2 tsp. garlic powder: Garlic powder brings a lovely, warm flavor that enhances the overall taste of the casserole.
- 1 tsp. dried sage: Sage contributes an herbal note that pairs perfectly with chicken and Alfredo sauce.
- one 15 oz. jar Rao’s Alfredo Sauce: The creaminess of the Alfredo sauce makes the layers indulgent and delightful.
- 4 Parmesan Cheese Folios, cut in half: These cheese layers substitute traditional pasta for a flavorful twist.
- 3 cups grated Mozzarella cheese: The gooey, melted goodness of Mozzarella is essential for a satisfying casserole topping.
How to Assemble Chicken Alfredo Lasagna Casserole

Assembling Chicken Alfredo Lasagna Casserole is a fun process that allows you to layer your favorite flavors. It’s a great way to get the kids involved in the kitchen too! Let’s walk through the steps together.
- Start by cutting up about 8 cups of diced chicken. Remember, a bit more or less won’t hurt! It’s all about personal preference.
- Next, chop up 1 lb. mushrooms and heat 1 T of olive oil in a large frying pan. Sauté the mushrooms until they’re nicely browned, and all their liquid has evaporated. This should take about 5 to 7 minutes. Once done, remove the mushrooms to a plate.
- In the same pan, add the chopped onion (adding a little more oil if needed), and cook the onion for about 3 minutes until it becomes translucent.
- Now, it’s time to add the Poultry Seasoning, garlic powder, and dried sage. Cook for another minute or two, allowing those flavors to meld together beautifully.
- Add the cooked mushrooms and diced chicken back into the pan. Gently stir to combine everything, ensuring that the spices coat the chicken and mushrooms evenly.
- Next, pour in the Rao’s Alfredo Sauce and stir to ensure the mixture is well combined. Cook this at a low simmer for about 10 minutes until the sauce thickens slightly.
- While that simmers, choose your favorite lasagna dish. I typically use one that measures about 7.5″ x 11.5″ x 3 inches deep. Spray the baking dish with non-stick spray to prevent sticking.
- Take the Parmesan Cheese Folios and cut them in half. Lay them down to cover the bottom of the dish, placing the straight edge against the side of the dish. For larger casserole dishes, you might need to use three Folios per layer.
- Spread half of the chicken and mushroom mixture over the Folios, making sure it’s evenly distributed.
- Sprinkle 1 1/2 cups grated Mozzarella cheese over the chicken and mushroom layer for that cheesy goodness.
- Make another layer with the remaining Folios, followed by the rest of the chicken and mushroom mixture, and top it off with another 1 1/2 cups grated Mozzarella cheese for a delightful finish.
- Preheat your oven to 375F (190C), and bake the casserole for about 30 to 35 minutes. You’re looking for the mixture to be bubbling hot and the top to be lightly browned.
- Once it’s out of the oven, let it sit for about 10 minutes before cutting it into eight pieces. And trust me, it will still taste fantastic if you can’t wait that long!
