Why You’ll Love This Jalapeño Buffalo Chicken Casserole

The Secret to Bold, Creamy Buffalo Sauce
Classic buffalo flavor is all about that tangy, slightly spicy sauce. For a Whole30, keto, and paleo-friendly take, use compliant ranch or mayo as the creamy base. Whisk together with your favorite hot sauce (look for sugar-free, clean labels), add a splash of apple cider vinegar, and season with paprika and garlic powder for extra depth. Fresh jalapeños are the game-changer—choose your heat level by seeding or leaving them whole.
Assembling a Show-Stopping Casserole
Once you’ve prepared your sauce and shredded your chicken, the rest comes together in minutes. Layer the chicken into a casserole dish, drizzle generously with buffalo sauce, and top with sliced jalapeños. For a touch of crunch, garnish with thinly sliced green onions and a sprinkle of almond flour or crushed pork rinds (totally optional but totally delicious).
Serving Suggestions for a Spicy, Low-Carb Casserole

If you’re not avoiding dairy, a sprinkle of crumbled blue cheese makes a delectable addition. This dish stays delicious for days—making lunch meal prep a breeze!
