Keto Buffalo Chicken Casserole

Break out a baking dish, preheat your oven and get ready to feed your whole family a weeknight dinner they’ll never forget! This keto buffalo chicken casserole recipe boasts big, bold flavors, quality fats from Bulletproof Grass-Fed Ghee and a supportive collagen boost from Bulletproof Unflavored Collagen Protein. Plus, this game-day comfort food keeps the carbohydrates in check by using spaghetti squash, along with your favorite low-carb buffalo sauce and mayonnaise.

As for the rest of the ingredients in this gluten-free buffalo chicken casserole recipe? All you’ll need from the grocery store are chicken breasts, eggs and a few familiar veggies. If you’re not following the keto diet, feel free to include sweet potato, too. Just don’t forget the jalapeno for a garnish for a crunchy punch of heat!

While it does take some prep time to bring this main dish together, the end result is so delish that it’s totally worth it. Just see the total time it takes for the first person to ask for seconds. Hint: Not very long.

Get started on this keto buffalo chicken recipe by grabbing a large bowl, a casserole dish and setting your oven to 425ºF. As the squash gets in its 20 minutes of cook time, the leek and carrots get beautifully caramelized in ghee, olive oil, or whatever quality fat source you choose. Throw in some garlic powder and other spices to give your veggies even more flavor.

Once all the yummy low-carb buffalo chicken casserole ingredients have been mixed together and transferred to a baking dish, you can relax (for at least an hour) while your oven does all the work. Top with green onions and drizzle your nicely browned buffalo chicken dip with hot sauce (Frank’s Red Hot, anyone?) for a spicy finale.
