How to Make Cheesy Chicken Lasagna Casserole

Ingredient Insights & Substitutions

Lasagna Noodles – No-boil noodles work if you want to skip a step, but traditional lasagna noodles provide a heartier bite.
Rotisserie Chicken – A flavorful, easy shortcut. Leftover roasted chicken or even shredded turkey works too.
Heavy Cream & Ricotta – Creates an ultra-rich, creamy sauce. If you prefer a lighter version, substitute half-and-half for the heavy cream.
Sundried Tomatoes – Add a tangy, umami depth that balances the richness of the cheese. If you’re not a fan, swap them out for roasted red peppers or sautéed mushrooms.
Baby Spinach – A pop of color and nutrients. Frozen spinach works too—just squeeze out any excess liquid before adding it.
Mozzarella & Parmesan – A combination of gooey and nutty goodness. Want a little kick? Try smoked mozzarella or pepper jack for a twist.

Tips & Suggestions

Want Extra Crunch? – Top with buttery breadcrumbs or crushed garlic croutons for a crispy topping.

Meal Prep Magic – Assemble in advance, refrigerate overnight, and bake when ready for an effortless dinner.
Pair It With – Serve with a simple green salad, garlic bread, or roasted veggies for a complete meal.
