We love making easy weeknight dinners, and casseroles are the perfect dish to meal prep ahead of time, like Broccoli Casserole, Tater Tot Casserole, and Tuna Noodle Casserole!

Chicken CasseroleEASY CHICKEN CASSEROLE

Easy Chicken Casserole is the PERFECT throw-together weeknight dinner recipe. You can make it ahead and freeze it, or put it together that night. This dish is quick, easy, and kid friendly, taking a total time of 45 minutes to make!

This chicken casserole is a great recipe for meal prepping. I like to make a double batch, and freeze it in catering dishes, so I can throw it straight into the oven to bake when I need it. This is a great potluck recipe, or for when you have company coming over.

HOW LONG WILL EASY CHICKEN CASSEROLE KEEP?

Chicken casserole will last in the refrigerator for 3-4 days, or in the freezer for 4-5 months. Make sure it is sealed in an airtight container to prevent freezer burn. Defrost in the refrigerator the day before serving.

You can also freeze this casserole cooked or uncooked, depending on your preference.

HOW TO MAKE CHICKEN CASSEROLE IN THE SLOW COOKER

  • In a large skillet, brown chicken breasts with butter on all sides.
  • Add everything to the slow cooker (except for the topping) and stir together.
  • Close the lid and set on high for a total time of 4 hours, or on low for 8 hours.
  • When time is up, remove the chicken and shred with two forks. Return to slow cooker and stir.
  • Add topping, and leaving the slow cooker on high crack the lid open slightly for 30 minutes. This mimics what happens when you bake the casserole, and makes the topping nice and crispy.

  1. This dish is yummy. My mother and I and one of two children loved it. I added small can diced jalapeños and extra milk for extra sauce. With Basmati rice it was delicious. Even the little leftovers mom and I shared because it was just that good. Thank you for the recipe.

  2. Hello Sabrina,
    Is this using four *whole* boneless breasts, or half-breasts? Looking forward to making this!
    Thank you.

  3. I followed the recipe, and baked it for 35 minutes. The chicken was done, but when I dished up, the sauce was runny on the bottom. What went wrong?

  4. This was a HUGE hit with my husband, who is an extremely picky eater. He kept asking for more several days after we’d finished our leftovers! I’ve NEVER had a response like this from him. Can’t wait to try more recipes!

    1. I love when recipes win over the picky eaters. 🙂 Thank you so much for coming back to let me know how much you all enjoyed it.

  5. I added egg noodles to seasoned water that I boiled the chicken in. I used no onion,, 1/2 cup frozen mixed veggies,substituted sugar free plain yogurt for sour cream, baked for 30 mins on 350 and my husband and I loved it.

  6. For the show cooler version it talks about adding everything to the crockpot. Does that mean that you are not sautéing the onions then and do you throw all the butter in?

    1. I have an aluminum insert in my slow cooker that allows you to sauté. You can always do that on the stove top if yours doesn’t have one. Hope this helps!
