My Tips for Making This Easy Confetti Chicken

  • Use any chicken that you have on hand. This recipe is great for utilizing leftover chicken breast or rotisserie chicken. You could also use leftover holiday turkey!
  • My husband loves the flavor of sharp cheddar cheese, and it’s what I used when I made the confetti chicken for these photos, but any shredded cheese will work fine.
  • Don’t have spaghetti noodles? You can substitute with another type of pasta.
  • This confetti chicken casserole is one of those versatile, everything-but-the-kitchen-sink recipes. Feel free to mix and match ingredients to suit your preferences. Don’t have green peppers? Use red. Don’t have cream of chicken soup? Swap it for cream of mushroom. It’s all good!
