Leftover Chicken Casserole

My Everyday chicken casserole recipe is the perfect way to use cooked leftover chicken and turn it into a tasty creamy casserole. This easy chicken casserole recipe combines simple ingredients, including bell pepper, celery, white onion, and noodles, then creates a creamy taste with dairy – butter, milk, and cheese.

Casseroles are easy to make!

One-pot meals are perfect for busy cooks who don’t have time to make “fussy” recipes. Casseroles are the easiest kind of meal for weekday dinners because they are whole meals baked in just one casserole dish. Indeed, there are so many advantages of casseroles, including:

  • If you have a pantry stocked with basic ingredients, then preparing a casserole dish is no big deal. No need to make a special shopping trip.
  • A tasty way to use up leftover meat and leftover vegetables.
  • Perfect for experimenting with different ingredients. Casseroles are truly forgiving, allowing you the freedom to add or reduce ingredients as per your taste.
  • Can be prepared ahead of time. Just cover and store in your refrigerator. Heat up your casserole when you are ready to eat, and you have a perfect meal on your table.
  • Can be frozen. When you make a family favorite, consider fixing two of them. Place the spare one in your freezer and bake when needed.
  • Easy clean up; only one dish to take care of.

How to Cook Chicken for a Casserole

Boil the chicken breast for ten minutes or until the chicken is no longer pink. Once the chicken is cool enough to handle, use two forks to pull the breast apart. If you want smaller pieces, you can shred the larger chunks with your hands.

Tips for Freezing Your Casseroles

Although most casseroles can be frozen, there are a few guidelines to follow for best results:

  • Starchy ingredients such as pasta, rice, beans, etc. should not be overcooked as they will become mushy when reheated. Cooking them al dente is ideal.
  • Use full-fat dairy products in casserole dishes. Using low-fat cheeses and milk will result in a rubbery texture once thawed and reheated
  • If your casserole includes a crunchy topping, wait until the serving day to add it. Otherwise, your crunchy topping will not be crunchy at all, but horribly soggy.
  • When placing in your freezer, cover your casserole with freezer paper or foil, not plastic wrap.
  • For best results, let the casserole dish thaw in your refrigerator while you’re at work. Once home, bake at 350 degrees until heated through.

    My husband and I enjoyed it however. I used sour cream with chives to spice it up. It almost tasted like a chicken alfredo dishl. My husband usually thinks my cooking is bland but he LOVED this one. When I make it again I’ll serve with noodles for a little more texture!

    DELICIOuS! Followed recipe exactly except for baking it in the oven. I just combined everything at the end and let it simmer on the stove for a few more minutes! Will definitely be making it again! Thank you for the great recipe.😊
