The Ingredients

Meat: Cooked chicken (we used a rotisserie chicken)

Pantry: Olive oil, all-purpose flour, dry lasagna pasta sheets.
Pantry Seasonings: Dry Italian herbs, garlic powder, ground nutmeg, black pepper

We made the white sauce from scratch but if you want to take a shortcut and purchase a jar of alfredo sauce, that works too.

Variations to Try: Recipes with a Twist

Spinach and Ricotta Alfredo Chicken Lasagna: Thaw and drain a 10-ounce package of frozen spinach. Spread a layer of ricotta cheese over each layer of pasta. Sprinkle the drained spinach evenly over the chicken in each layer.

Mushroom and Chicken Alfredo Lasagna: Sauté 2 cups of sliced mushrooms (such as cremini or button mushrooms) in olive oil until they are browned and tender. Add the mushrooms to each layer of the lasagna along with the chicken.

Sun-Dried Tomato and Chicken Alfredo Lasagna: Chop 1 cup of sun-dried tomatoes and add them to each layer along with the chicken. You can also sprinkle a little bit of the oil from the sun-dried tomatoes for extra flavor.

Helpful Tips for Making Chicken Alfredo Lasagna

If you want to add frozen spinach, make sure to thaw and drain it well to avoid excess moisture in the lasagna.
When you cook the pasta, make sure to use plenty of salt in the water. This is your chance to season the pasta from the inside out.
Cook the pasta to al dente, as they will continue to cook in the oven and absorb the sauce.
Cover the lasagna with foil during the first half of baking to prevent the cheese from browning too quickly.
Allow the lasagna to rest for 10 minutes after baking. This helps it set and makes it easier to cut and serve.

Storing Leftovers

Allow the lasagna to cool to room temperature before storing it.

Refrigeration: Cover the lasagna with plastic wrap or aluminum foil, or transfer it to an airtight container. Store in the refrigerator for up to 3 days.

Freezing: To freeze, wrap the entire lasagna tightly in plastic wrap, then cover it with aluminum foil or place it in a freezer-safe container. Label with the date and freeze for up to 3 months.

Reheating: Thaw the frozen lasagna in the refrigerator overnight. Reheat in a 350°F oven, covered with foil, for 25-30 minutes or until heated through. For quicker reheating, microwave individual portions until warm.

With the convenience of rotisserie chicken, this alfredo lasagna is perfect for those busy nights when you want something hearty without all the hassle.
