Creamy Buffalo Chicken Casserole

Upgrade your dinner menu with this Creamy Buffalo Chicken Casserole.

A hearty, warm and flavorful dish. I love casseroles this time of year and being from Minnesota, it’s a dish that has some pretty strong roots – also known as  a “hot dish.” Whatever you choose to call it, this Creamy Buffalo Chicken Casserole is truly a must try. It’s made with a combination of tender chicken (shredded or cubed), cauliflower rice, onion, red pepper, carrots and is held together with the most creamy and flavorful sauce made of buffalo sauce, mayo and eggs. Can you say comforting? You can choose your level of heat by adding a Mild Buffalo Sauce or Hot Buffalo Sauce. For family friendly, I recommend sticking with a mild sauce.

Made with Tessemae’s Buffalo Sauce.

We partnered with our friends at Tessemae’s to bring you this incredibly delicious Creamy Buffalo Chicken Casserole featuring buffalo sauce. While making your own buffalo sauce is always an option, we love the convenience of Tesseame’s Buffalo Sauces. With two levels of heat (Mild and Hot), you can choose what suits your preferences. The buffalo sauces are made with only clean ingredients and are Whole30-approved, have no sugar-added, are dairy-free, gluten-free and vegan-friendly. Best of all, they’re packed with flavor and definitely a staple in my house!

You can purchase Tessemae’s Buffalo Sauce online or in stores

Serve it up with your favorite side.

You really can’t go wrong no matter what you serve with this Creamy Buffalo Chicken Casserole. In fact, you really could just serve it on its own as it’s complete with plenty of satisfying protein and fats. However, if you want  to add a little bit more to the plate, you have options. To keep this recipe lower in carbs, I recommend serving it with a green veggie such as broccoli, green beans, Brussels or a side salad. With that said, my ultimate favorite way to serve this recipe is over a baked potato or sweet potato. It adds a little starch (and fiber) to the meal and is so so comforting and delicious!

Don’t forget the drizzle of ranch!

The pairing of Buffalo sauce and ranch is a combo that’s adored by many! Adding a drizzle to your serving of Creamy Buffalo Chicken Casserole is really a no brainer. It adds both creaminess and flavor to this recipe and really takes it to the next level. Tessemae’s Ranch is another staple in my house. I love the creamy texture, the flavor (the best) and the ingredients it’s made of. Many people also like the combination of blue cheese and buffalo sauce. So if that’s your thing and you’re not in need of a recipe that’s dairy-free (or Whole30), you could also add a sprinkle of your favorite blue cheese crumbles.

It’s time to give this Creamy Buffalo Chicken Casserole a try!

Oh and before I forget, this recipe is also freezer-friendly. So if you’re looking to stock your freezer with some tasty meals to enjoy in the future, this recipe is perfect for that!
