How to Make It (WATCH HERE)

Marinate the Chicken
Start by mixing your marinade. Combine buttermilk, garlic, mustard, spices, and chicken thighs. Let it soak for at least 20 minutes to tenderize and flavor the meat
Make the Ranch
Blend together mayo, sour cream, buttermilk, herbs, and seasonings until creamy and smooth. This ranch doubles as a dressing and sandwich spread
Prepare the Buffalo Sauce
Simmer butter, garlic, buffalo sauce, and brown sugar until rich and glossy. This garlicky, buttery hot sauce is the real star
Bread and Fry the Chicken
Dredge marinated chicken in seasoned flour and fry until golden brown and crisp, about 6 to 8 minutes per piece or until 165°F internally
Assemble the Sandwich
Toast your croissants. Toss romaine with ranch and Parmesan. Spread ranch on the croissant bottoms, add buffalo chicken, salad, and more cheese. Cap with the croissant tops and devour immediately
