Holly’s Recipe Highlights: Cheesy Chicken Casserole

  • Flavor: This casserole is rich, creamy, with savory chicken, sharp cheddar cheese, mild green chiles, and a hint of warmth from chili powder and seasoned salt.
  • Why Make It: Made with leftover chicken or poached chicken breasts, this casserole is super quick to prepare. It can even be prepped ahead of time!
  • Recommended Tools: You’ll need a pot, a skillet, a large mixing bowl, and a 9×13-inch casserole dish.
  • Serving Suggestions: Pair with a simple vegetable side, such as roasted asparagus or honey roasted carrots, to balance the rich and creamy flavors.

Ingredient Notes

  • Cooked Chicken: Rotisserie chicken, leftover baked chicken, or poached chicken all work for this casserole. Turkey or ham can also be used.
  • Pasta: Any medium pasta will work in this recipe. But be sure to cook it just to al dente, so it doesn’t become too soft while baking.
  • Red Bell Pepper: It adds a touch of sweetness and color to the casserole. Green bell pepper can be used instead for a slightly sharper, more savory flavor.
  • Chili Powder: It adds a warm, gentle hint of spice without making the casserole overly hot. Taco seasoning can be used as a substitute, but start with less since the flavors are stronger.
  • Condensed Cream of Chicken Soup: It creates a creamy, flavorful sauce quickly and helps bring the casserole together with minimal prep. Any cream-based soups can be used, so use whatever you have in your pantry.
  • Sharp Cheddar Cheese: Sharp cheddar gives the most flavor, while mild cheddar creates a softer taste. For extra spice, replace part of the cheddar with pepper jack cheese.

Leftovers You’ll Love

Keep leftovers in an airtight container in the refrigerator for up to 4 days and in the freezer for up to 3 months.

Notes

Any medium pasta will work in this recipe. Be sure to cook it so it’s still a bit firm, it’ll cook more in the oven.
This recipe is versatile, you can swap out the chicken for ham or turkey.
If adding extra vegetables, ensure they’re pre-cooked (leftovers work well).
To Add a Bread Crumb Topping: Combine 3 tablespoons panko crumbs with 1 tablespoon melted butter (add a sprinkle of garlic powder, salt & pepper). Sprinkle over the casserole and bake as directed.
Keep leftovers in an airtight container in the refrigerator for up to 4 days.

  1. Cooking is not my greatest talent, but this recipe is fantastic! Everyone who ate it raved about how good it was and said they couldn’t believe “I” made it
    My husband is still talking about it today!5 stars

  2. This dish is delicious! Unfortunately I did something wrong and mine is soooo runny! I don’t know what I did wrong nor how to correct it. It’s more like a cream based soup or a pot pie than a casserole.

    I will definitely try it again, though.5 stars

      1. Hi Holly

        I used condensed right from the can. No liquid other than the milk was added.

        Thanks

      2. Hmm, I can’t say for sure what went wrong as I haven’t had that problem before. I’m sorry it didn’t work out for you.

  3. We are making this and having a lot of fun! We want to eat it later. Should we cook it and reheat it later, or should we not cook it at all, pop it in the fridge and just bake it once? So far it smells delicious!

  4. Loved this recipe! Even my husband, who is not a casserole fan, liked it! Will be making again for years to come!5 stars

  5. I love this recipe but it always makes so much and we are not big on leftovers, do you have a recipe for an 8×8 or 9×9 pan???

    1. Hi Carrie, we don’t have a version of this recipe for an 8×8 or 9×9 but you could half the recipe and bake it in a 9×9 pan if you would like :)

  6. I made this delicious casserole tonight and it was a hit! I used cream of onion soup instead of cream of chicken for a little more flavor. I also cooked my chicken in my pressure cooker with Holly’s recipe before assembling the casserole. It took under an hour from start to finish!5 stars

  7. What could I sub for the chicken soup? I have all the ingredients but that one. Love your recipes! They are great for my family of 10

  8. Holly, I just want to tell you how much I love your recipes. I get so excited to see a new one and they’re always so delicious. Thank you and God bless you and your family.5 stars

  9. One of my all time favorite recipes. My husband and daughter love it, as well. My picky daughter didn’t pick anything out of it. She devoured the first serving and came back for seconds. Will definitely make this over and over again.5 stars

  10. I made the cheesy chicken casserole, and although the nutrition information is noted, it does not specify what the serving size is for the nutritional information provided. Would you happen to know what serving size that information is based on? In

    1. Hi Ronda, the nutrition information is for ⅙ of the casserole. This would be approximately 1 to 1½ cups per serving.

  11. Great recipe!! My husband does all the cooking but I will get in the kitchen if I find a recipe I wanna try…We are a family of 6 so this was perfect..It pleased everyone even the picky eater..Definitely will make again. Thank you

  12. Loved this! I cut the chicken up and baked it seasoning it with black pepper, seasoned salt, onion powder and smoked paprika. I didn’t have shells so I used rotini. Otherwise followed the recipe. Will definitely make this again!5 stars
