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.

    THIS. IS. AMAZING. The perfect combination of all my favorite foods and flavors! I made a casserole for myself thinking I’d have it for lunch and/or dinner the rest of the week but my family wound up eating the entire thing as soon as it came out of the oven. SO tasty and smells incredible, can’t wait to make it again!

    Loved this recipe! Erin was even nice enough to quickly answer my question about using frozen broccoli (you can!) on Instagram since I didn’t have fresh. My husband raved about it!

    Made this over the weekend and it was so good! I enjoyed the fact it didn’t feel like a typical heavy casserole but more of a bowl with yummy spicy goodness! Definitely a recipe that will stay in my books.

    We LOVE this meal-
    My toddler clears his whole plate and asks for more.
    My husband’s favorite flavor is Buffalo sauce so he’s an easy win.
    I don’t eat cheese so we used a vegan bleu cheese dressing on the side and only put cheese on individual servings.

    I’ve made it for several other families and have been asked for the recipe so many times that I now print this page to give to others.
    Incredible meal.

    Such a great meal prep recipe! I add broccoli to up the veggie content even more. One of the few meal preps I make that I’m not sick of by the end of the week. Delish and so easy too!

    Never would have put together this combo, but wow! It was so good! Super quick one pan meal for any night of the week, reheats well too. I added blue cheese crumbles on top. I will say I overcooked mine a bit, your oven may need a shorter cook time.

    This is by far my favorite “all in one meal”. You have everything you need! Potato, veggie, protein, cheese 🙂 I’m obsessed with this casserole! One serving is filling and the leftovers are just as good!

    This was an amazing recipe! I actually made half with potatoes and half with sweet potatoes and it came out perfectly! This will be another staple in our household. I also shared it with my mom and sister. Love the spicy sweet potato, it totally works. Thanks Erin for another winning dish!

    My fiancé and I have probably made this one 10+ times and is in heavy rotation! We’ve switched it up here and there with sauce combinations, different cheeses, etc. but it’s always soo good! Best combo is 1/2 cup bbq sauce, 1/2 cup franks, topped with TJs unexpected cheddar shreds! We love that we can make this one time and we each get 3 nights of dinner out of it! Perfect meal prep dinner!
