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 them just to al dente, so they don’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.

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).
