Casseroles and one-pan meals are my love language! Also anything Buffalo Chicken. Which makes this meal a winner in my book! All of my kids LOVE buffalo anything (as long as I use mild sauce), so it’s also great for the whole family. This Loaded Potato and Buffalo Chicken Casserole is so simple to make, and it only uses 5 ingredients. You truly can’t beat that!

What Ingredients You Need to Make This Loaded Potato & Buffalo Chicken Casserole
Like I mentioned, you only need 5 (maybe 6) ingredients to make this!
- Chicken – I love to get my organic, free-range chicken breasts from Butcher Box. They deliver the meat straight to your doorstep, and it’s seriously the best chicken I’ve ever had!
- Potatoes – For this recipe, you can use 1 lb of yellow or red baby potatoes or 4-5 russett potatoes (peeled or not, up to you!). If you use baby potatoes, I like to cut them into halves if they’re smaller, or fourths if they’re on the bigger side.
- Buffalo Sauce – Some of my favorite healthier (and Whole30 compliant) brands of buffalo sauce are: The New Primal, Tessemae’s, and Primal Kitchen.
- Green onions
- Bacon – I also love to get this from Butcher Box. It’s sugar free and so delicious!
- Green onions
- Ranch dressing – My favorites are Tessemae’s or Sir Kensington’s!
You can get both of the sauces needed for this recipe on Thrive Market. Thrive is an online store that sells pantry staples for cheaper than retail price. I love getting everything delivered to my doorstep! You can use this link to get 25% off your first order plus a free gift!
I used my 9×13 Staub Baking Dish for this recipe. Any 9×13 pan will work well!

How to Make This Whole30 Loaded Potato & Buffalo Chicken Casserole
-
Cook your bacon. I like to do this using my No Mess Oven Baked Bacon method! Drain it on a paper towel lined plate while you make the casserole.
-
Preheat your oven to 450. Spray a 9×13 casserole dish with avocado or olive oil. In a large bowl, combine the diced potatoes and buffalo sauce. Toss to coat, then use a slotted spoon to remove the potatoes and add them to the baking dish in a single layer. Add the raw chicken pieces to the same bowl with the remaining buffalo sauce and toss. Keep the bowl in the fridge and let the chicken marinate while the potatoes cook.
-
Cook the potatoes for 30-35 minutes, tossing every 10 minutes, until cooked through and crispy. Reduce the oven temperature to 400. Add the raw marinated chicken pieces on top of the potatoes along with the bacon pieces. Cook for an additional 15-20 minutes until the chicken is cooked through. Top with green onions and a drizzle of ranch dressing and serve. Enjoy!

this one is a winner and will be added to our family’s rotation!
This was INSANE, and so so easy. My husband has requested it be made once a week! It’ll make great leftovers too!
So good! One of those meals you eat then can’t wait to eat the leftovers! Can’t wait to make again!
So easy and delicious!! Perfect for a busy weekday or game day meal!
Easy recipe to follow and delicious at the same time. We will definitely make it again.
I made this tonight for dinner and it was a family hit! Everyone raved about it and asked where I got the recipe from. I will definitely be making this again. Thank you for creating and sharing whole meals! 🙂
This was so amazing! So easy, and I had precooked chicken to make it even easier! I also added broccoli which was a nice mix in! I doubled it for my family and there was only 1 serving left! It’s a must make recipe for sure! Yum 😋
Like most of the recipes I’ve tried of Mary’s, this one was delicious! The Buffalo sauce added just the right amount of heat! Super easy to prep, especially with my 14 yo daughters help. ☺️
Thank you so much!!
This dish is awesome! My whole family loved it, even my 3 year old and 5 year old. Putting the ranch on took some of the heat down so the kids could tolerate the spice. I think next time I roast potatoes I am going to toss them in buffalo sauce just because that was my favorite part of the meal!
Easy and delicious!
