Ingredients in Crispy Buffalo Chicken Croissant Sandwich

(Note: full measurements are in the recipe card below.)

Chicken Marinade:

Boneless, skinless chicken thighs marinated in buttermilk, garlic, mustard, paprika, onion powder, salt, and pepper. This tenderizes the meat and infuses it with flavor.

Crispy Breading:

Flour seasoned with thyme, paprika, garlic powder, onion powder, salt, and pepper. It gives that golden crunch everyone loves.

Homestyle Buttermilk Ranch:

A creamy, tangy dressing made with mayo, sour cream, buttermilk, chives, parsley, lemon juice, and a touch of seasoning. Perfect for drizzling or dipping.

Garlic Infused Buffalo Sauce:

Hot buffalo sauce enhanced with butter, garlic, and brown sugar. Sweet, spicy, and garlicky—utterly addictive.

Croissants:

Buttery, flaky, and soft—the perfect vessel for holding all that crispy, saucy goodness.

Instructions

Here’s how to turn this flavor-packed vision into reality:

Marinate the Chicken:

Combine chicken thighs, cold buttermilk, garlic, onion powder, yellow mustard, paprika, salt, and pepper in a large bowl. Cover and refrigerate for at least 2 hours or overnight for maximum flavor.

Prepare the Breading:

In a shallow dish, mix together flour, thyme, onion powder, garlic powder, black pepper, salt, and paprika.

Bread the Chicken:

Remove chicken from marinade, letting excess drip off. Dredge each piece in the seasoned flour, pressing lightly to adhere.

Fry the Chicken:

Heat oil in a frying pan over medium heat. Fry the breaded chicken thighs until golden brown and cooked through, about 4–5 minutes per side. Transfer to a rack or paper towels to drain.

Make the Buffalo Sauce:

In a small saucepan, melt butter with garlic, then whisk in buffalo sauce and brown sugar. Simmer briefly to combine flavors.

Toss Chicken in Sauce:

Once chicken is crispy, coat each piece in the buffalo sauce until evenly coated.

Make the Buttermilk Ranch:

In a mixing bowl, whisk together mayo, sour cream, buttermilk, chives, parsley, lemon juice, onion powder, garlic powder, salt, pepper, and sugar. Chill until ready to serve.

Assemble the Sandwich:

Slice croissants in half, layer buffalo chicken, and drizzle generously with buttermilk ranch. Add lettuce, tomatoes, or pickles if desired. Serve immediately.
