• 4 tablespoon melted butter (plus more for toasting buns)
• 4 brioche burger buns
• spring mix or lettuce, for serving
• 1 cup all purpose flour
• ¼ cup potato starch
• ½ teaspoon dried oregano
• ½ teaspoon smoked paprika
• 1 teaspoon sea salt or kosher salt
• ½ teaspoon freshly ground black pepper
• ¼ teaspoon cayenne
• ½ teaspoon garlic powder
• ½ teaspoon onion powder
• ¼ cup sour cream + 1 tbsp
• 3 tablespoon blue cheese crumbles

• 1 teaspoon dried chives

How to Make the Sandwich

1. Slice each chicken breast in half lengthwise to create thinner pieces.
2. Place chicken in a resealable bag or under plastic wrap and pound to about 1/4″ thickness with a meat mallet or rolling pin; trim if needed.
3. Transfer chicken to an airtight container or resealable bag and pour in enough buttermilk to fully coat the pieces.
4. Refrigerate and marinate the chicken at least 4 hours or up to overnight.
5. Whisk all breading ingredients together in a large bowl until well combined.
6. Stir a few tablespoons of the buttermilk marinade into the dry breading, adding gradually to form craggly bits.
7. Allow excess buttermilk to drip off each piece before dredging.
8. Dredge each chicken piece in the breading mixture, coating evenly on all sides.
9. Place breaded chicken on a plate and let rest at room temperature 15 minutes or refrigerate up to 2 hours to set the crust.
10. Pour 2–3 inches of neutral oil into a large skillet, heat over medium-high 5–7 minutes, and test oil by dropping a pinch of breading to ensure it sizzles and browns without dissolving.

11. Fry chicken in batches of two, lowering pieces away from you, and cook 3–4 minutes per side until golden, crispy, and the internal temperature reaches 165°F.

    

12. Transfer cooked chicken to a wire rack set over a baking sheet to drain excess oil and keep the crust crisp; repeat with remaining pieces.
13. Melt butter and whisk together with hot sauce in a wide bowl or baking dish to make the buffalo sauce.
14. Dip each fried chicken piece into the buffalo sauce to coat both sides, then return to the wire rack.
15. Finely chop fresh dill.
16. Combine chopped dill, sour cream, blue cheese crumbles, minced garlic, lemon juice, dried chives, onion powder, salt, and pepper in a bowl and stir until smooth to make the dilly blue cheese sauce.
17. Toast brioche buns cut-side down in a little melted butter until golden and fragrant.
18. Assemble sandwiches: place spring mix or lettuce on the bottom bun, top with buffalo chicken, spoon on dilly blue cheese sauce, and crown with the top bun.

Pro Tips for Perfect Crunch

• Marinate 4–24 hours: soaking in buttermilk builds flavor and tenderness—overnight is ideal.
• Pound chicken to ¼ inch thickness so it cooks quickly and evenly every time.
• For extra-craggy breading, stir a few tablespoons of the marinade into the dry mix to build crunchy clumps that fry up crunchy and delicious.
• Rest breaded chicken 15 minutes at room temperature or chill up to 2 hours—this helps the crust stick firmly.
• Heat 2–3 inches of neutral oil over medium-high for 5–7 minutes; test with a pinch of breading—if it crisps up without falling apart, you’re good to go.
• Fry in small batches (two pieces at a time) to keep oil temperature steady—never overcrowd the pan.
• Drain chicken on a wire rack over a baking sheet to keep that crust crisp—skip paper towels to avoid sogginess.
• Toast the brioche buns in butter right before assembling for a rich, golden crunch; for fresh contrast, add a scoop of tangy vinegar coleslaw (no mayo).
• Make the dilly blue cheese sauce up to 2 days ahead to save time and meld the flavors, or grab your favorite bottled blue cheese dressing for a shortcut.
• No potato starch? Substitute with an equal amount of cornstarch for still crispy results.
• Check chicken is done with an instant-read thermometer; it should reach 165°F at the thickest point.
• Leftovers? Reheat in an air fryer at 350°F for 5–7 minutes or in an oven at 350°F for 20–30 minutes to bring back that fresh crisp.

Easy Swaps and Add-Ins

This fried buffalo chicken sandwich is super flexible so you can adapt it based on what’s in your pantry or your flavor preferences. Here are some handy swaps:

No potato starch? No worries! You can use the same amount of cornstarch in your breading mix with great crispy results. Blue Cheese Sauce Short on time or not feeling homemade? Grab your favorite bottled blue cheese dressing to top your sandwich instead. But trust me, the homemade version is worth it if you can spare the few minutes! For refreshing crunch that cuts the heat, pile on a scoop of this vinegar coleslaw for BBQ and sandwiches.

Keeping and Reheating Leftovers

Storing: Leftovers are a lifesaver! Keep any extra chicken in an airtight container or resealable bag in the fridge for up to 4 days.

Reheating: To bring back that just-fried crunch, pop your leftover fried buffalo chicken sandwich chicken in an air fryer at 350°F for 5–7 minutes, or warm in the oven at 350°F for 20–30 minutes. Avoid the microwave, which can make the crust soggy.

Common Recipe Questions

• Can I bake the chicken instead of frying it? Absolutely! Baking gives a lighter sandwich, though it won’t be quite as crisp. Bake on a wire rack at 425°F for 20–25 minutes, flipping halfway, until the internal temp hits 165°F.
• Can I use chicken thighs instead of breasts? Yes! Boneless, skinless thighs are juicier and work great here. They’re usually thicker, so just keep an eye on doneness and cook until 165°F internally.
• What if I don’t have potato starch? Use cornstarch in the same amount. It still adds great crispness to your breading.
• How long should I marinate the chicken? At least 4 hours is recommended; 24 hours max helps lock in the best moisture and flavor.
• Can I make the blue cheese sauce ahead of time? Yes, it actually tastes better after resting for a day or two. Store it in the fridge in an airtight container.
• How should I store and reheat leftovers? Keep leftovers in an airtight container in the fridge for up to 4 days. Reheat in an air fryer at 350°F for 5–7 minutes or the oven at 350°F for 20–30 minutes to keep the crunch.
• How spicy is this sandwich and can I adjust the heat? The heat comes from the hot sauce and cayenne in the breading. You can reduce or skip cayenne and dial down the hot sauce if you prefer less heat. Or add more if you like it fiery!
