The best potato casserole recipe

I love a good casserole. I couldn’t always say that, as I grew up totally hating the idea of a one-dish meal. My food… touching? Nope!

Thankfully, I eventually got over that and realized just how wonderful casseroles can be. They’re easy, quick, and totally awesome for feeding a bunch of people. Plus, they taste fantastic!

This buffalo chicken sweet potato casserole is no different. Right away, it became a top favorite in my household and will without a doubt be a regular on our kitchen table. It’s sweet but also savory, and it’s without a doubt incredibly filling.

Next time you’re in the mood for a chicken casserole recipe, chicken sweet potato casserole is a must. With a little bit of buffalo sauce, this dish has a nice kick that’s perfect for anyone who likes spiciness, but not overwhelming to those who don’t.

Ingredients needed to make this chicken casserole

Buffalo chicken sweet potato casserole is made with more than just chicken and sweet potatoes. It includes broccoli, cheese, turkey bacon, and a variety of spices and sauces! Here is a list of everything you’ll need:

  • Chicken breasts
  • Sweet potatoes
  • Broccoli
  • Buffalo sauce
  • Avocado or olive oil
  • Salt
  • Pepper
  • Garlic
  • Cheddar cheese
  • Green onion
  • Turkey bacon
  • Ranch

Kitchen tools used to make sweet potato casserole

There aren’t many kitchen tools that are needed to create this dish. In total, you’ll only need a casserole dish, cutting board, chopping knife, and two mixing bowls! A 9×13 casserole dish will work perfectly for this recipe, but any size is doable. At least one of your mixing bowls should be large enough to easily stir and toss ingredients.

As far as ingredient amounts go, it will be helpful to have the following measurement tools: 1/4 cup, 1/3 cup, 1/2 cup, 1 cup, and 1 tsp.

How to make buffalo chicken sweet potato casserole

This is one of my favorite chicken casserole recipes, and not just because it tastes great! The recipe is foolproof and doesn’t require any extensive prepping. In fact, you’ll only need about 10 minutes! After that, throw it in the oven. In just 50 minutes, you’ll have a warm, delicious, satisfying casserole. This recipe yields 8 servings.

To start making this chicken casserole recipe, preheat the oven to 425F and grease a 9×13 casserole dish.

Prepare your chicken, potatoes, and broccoli by cutting them into small, 1 inch pieces.

In a small bowl, mix the buffalo sauce, avocado oil, salt, pepper, and garlic.

Then, in a large bowl, add your sweet potatoes and half of the buffalo sauce mixture. Toss until well-combined.

Pour the sweet potatoes into the casserole dish and roast for 30 minutes, flipping half way through.

While the potatoes are baking, add the chicken and broccoli to the bowl the sweet potatoes were in. Add the remainder of the buffalo sauce and toss to coat completely.

After the potatoes have baked for 30 minutes, add the broccoli and chicken on top.

Bake for 20-25 minutes or until the chicken reaches an internal temperature of 165F.

Remove the dish from the oven and top with cheese, green onion, and cooked bacon. Place back in the oven for five more minutes or until the cheese has melted.

Let cool for a few minutes. Finally, add any remaining toppings like ranch or blue cheese, and enjoy!

Casserole cooking tips

To make your casserole the best that it can be, here are a few tips that you may find helpful.

Preparing the chicken breasts
I recommend using about 2 lbs of chicken breasts for this recipe. That will amount to about 3 large breasts. Cut into 1 inch cubes.

Dicing the potatoes
Dice the sweet potatoes into 1 inch cubes, and nothing larger. This size will allow the potatoes to cook thoroughly and get nice and crispy! You can leave the skin on or take it off. I personally like to leave it on!

How to store leftover casserole
Any leftover casserole can be stored in the refrigerator for up to 5 days. If you’d like, you can freeze this recipe in an airtight container or freezer bag.

How to make vegetarian-friendly buffalo chicken sweet potato casserole

Making a vegetarian-friendly buffalo chicken casserole is so easy. In this recipe, there are two non-vegetarian ingredients: The chicken and the bacon. You can opt to simply omit these ingredients, or you can use plant-based alternatives.

If you go with the latter and use plant-based chicken, be sure to review the cooking instructions for that specific brand. You most likely will not need to bake it for 25 minutes.

When using plant-based bacon, cook as directed per the brand’s packaging, and sprinkle on top of the fully cooked casserole.

    Absolutely perfect for a fall/winter or rainy day and so easy to make. The combination of flavors and ease of throwing it all together in the oven makes this one a winner and a total repeat on the weekly meal plan.

    I’ve made this numerous times and it’s definitely a family favourite! I tend to use less hot sauce because I can’t handle much heat haha. I’ve also added other veggies I needed to use up like carrots, cauliflower, white potatoes. I also divide it up into meal size containers and freeze them (have for up to 4 months) and defrost over night for my lunch. Love it!

    Have been on a Buffalo chicken kick and this is one of my favorites!! Made this initially as a quick weeknight dinner.

    P.S. tastes EVEN BETTER the next day. The broccoli soaks up all the flavor and makes the most delicious bite!!!

    Love it for lunches. It reheats well…I just add the cheese, ranch, and more hot sauce as I am reheating so it doesn’t dry out.

    I was a little hesitant about this recipe but wanted something with sweet potatoes so thought I’d give it a whirl. My husband and I both loved it! It was easy and really good. It was a little spicy for the kiddos but they even kept eating it because it was so good.

    This casserole is soo good! We opted out on the bacon and it was still delicious!! My husband said next time we will have to try it with because he’s a turkey bacon lover! This dish tasted even better the next day when the flavors could all soak up together.. so yum!

    This is one of my favorite weeknight recipes! I have made it twice already and cannot wait to make it again. I just would like to comment that it definitely takes more than 10 minutes to prep everything, including cutting all the veggies/chicken and then cooking the bacon.

    This was very good, loved the flavors and it was super easy to make! We subbed some regular potatoes in for some of the sweet potato. My family found it a bit too spicy. I would for sure make it again but I would swap half the hot sauce for ranch or sour cream.
