This is a copycat of KFC’s Crispy Colonel — a buttermilk-brined, double-dredged fried chicken breast on a toasted brioche bun with peppery mayo and bread-and-butter pickles. The honest reason to make it at home: you control the oil quality, the salt level, and the thickness of the chicken, and it costs a fraction of the drive-through price.
Before you start
Two things actually determine whether this sandwich works. First, oil temperature: keep it between 325°F and 350°F throughout the fry. A cheap clip-on thermometer handles this — without one you’re guessing, and the coating will either burn or turn greasy. Second, the double-dredge only builds those craggy ridges if the buttermilk brine is still wet on the chicken when it hits the flour the second time; don’t shake off too much liquid between dips or you’ll get a smooth, thin crust instead of a crunchy one. If you don’t have buttermilk, mix 1½ cups whole milk with 1½ tablespoons white vinegar or lemon juice, let it sit five minutes, and use it the same way — it works.
Troubleshooting
- Coating slides off during frying: The chicken was too dry going into the second flour dredge, or the oil was too hot and the crust set before it bonded. Make sure the surface is visibly wet before the final dredge, and verify your oil temp before each batch.
- Chicken cooked through but bun is soggy by the time you eat: The chicken sat in a closed container or was covered while resting. Rest it on a wire rack uncovered — even a cooling rack set over a sheet pan works — so steam escapes instead of softening the crust.
- Coating is pale and greasy, not golden: Oil temperature dropped when you added the chicken. Fry in smaller batches and give the oil a minute to recover between them. Crowding is the most common cause of greasy fried chicken at home.
- Chicken is 165°F inside but the coating looks dark: Your oil ran too hot, likely above 360°F. Lower the heat and use a thermometer rather than eyeballing color — the coating browns faster than the interior cooks, especially with thicker fillets.
- No brioche buns available: A standard potato roll or a plain soft hamburger bun works fine here. Butter and toast it in a dry skillet until golden — that step matters more than the specific bun type.
Leftovers and meal prep
Fried chicken fillets keep in the fridge for up to 3 days in an airtight container. Reheat them on a wire rack in a 375°F oven for 10–12 minutes — this is the only method that brings the crust back without turning it rubbery; a microwave will make it soft and sad. For meal prep, you can bread the raw chicken fillets and freeze them on a sheet pan until solid, then transfer to a zip bag; fry straight from frozen at 325°F, adding 4–5 minutes to the cook time and confirming 165°F internal before serving. The peppery mayo keeps refrigerated for up to a week, so make a double batch and use it on sandwiches all week.
KFC Crispy Colonel-Style Sandwich (Copycat)
Ingredients
Buttermilk Brine
- 1.5 cup cultured buttermilk, cold Full-fat preferred for best tenderness
- 1 tbsp hot sauce Crystal or Frank’s for balanced heat
- 1.5 tsp kosher salt Diamond Crystal; reduce to 1 tsp if using Morton’s
- 1 tsp ground black pepper Freshly ground for aroma
- 1.25 lb boneless, skinless chicken breasts Cut into 4 equal fillets (about 4–5 oz each) and pounded to 1/2-inch thick
Seasoned Flour Dredge
- 1.5 cup all-purpose flour Unbleached, high-quality brand for best crust
- 0.33 cup cornstarch For extra crispness and lightness
- 1 tbsp kosher salt Season the flour boldly to carry flavor through the crust
- 2 tsp garlic powder Granulated works too; powder adheres better in dredge
- 2 tsp onion powder Sweet-savory backbone in the crust
- 1 tsp paprika Sweet or smoked; smoked adds subtle campfire depth
- 1 tsp ground white pepper Classic for that nostalgic fast-food warmth
- 0.5 tsp baking powder Lightens the crust for a delicate shatter
- 0.5 tsp cayenne pepper Optional, for a gentle kick
- 1 tsp granulated sugar Balances the spice and promotes browning
Egg Wash
- 2 large eggs Room temperature for smoother coating
- 2 tbsp buttermilk Loosens the egg wash for even coverage
For Frying
- 6 cups neutral frying oil Peanut, canola, or sunflower; high-heat and fresh oil for best flavor
Peppery Mayo (Colonel-Style Sauce)
- 0.5 cup mayonnaise Duke’s or Hellmann’s preferred for body and tang
- 1 tsp Dijon mustard Adds gentle heat and emulsified sheen
- 1 tsp lemon juice Fresh-squeezed for brightness
- 1 tsp hot sauce Adjust to taste for a mild kick
- 0.25 tsp garlic powder Sub with a tiny grate of fresh garlic for a sharper bite
- 0.25 tsp ground black pepper Freshly ground for aroma and speckled look
- 0.125 tsp kosher salt Season to taste
- 0.5 tsp granulated sugar Optional, rounds the sauce
Assembly
- 4 whole brioche or potato sandwich buns Soft, slightly sweet buns echo the fast-food classic
- 1 tbsp unsalted butter For toasting buns to a light golden sheen
- 8 slices bread-and-butter pickle chips Or dill pickle chips if you prefer tangier
Instructions
- Pound and brine the chicken (45 minutes): Trim the chicken and pound to roughly 1/2 inch thick for even cooking. In a bowl, whisk buttermilk, hot sauce, salt, and black pepper. Submerge the chicken, cover, and refrigerate for 45 minutes to tenderize and season deeply.
- Make the peppery mayo (5 minutes): In a small bowl, whisk together mayonnaise, Dijon, lemon juice, hot sauce, garlic powder, black pepper, salt, and sugar until smooth. Cover and chill.
- Mix the seasoned flour and egg wash (10 minutes): In a shallow dish, combine flour, cornstarch, salt, garlic powder, onion powder, paprika, white pepper, baking powder, cayenne, and sugar. In a second dish, whisk eggs with buttermilk. Tip: Sprinkle 1 tablespoon of the buttermilk brine into the flour and rub it in with your fingertips—those tiny clumps become extra-crispy crags.
- Dredge for maximum crunch (5 minutes): Lift one piece of chicken from the brine, letting excess drip off. Press firmly into the seasoned flour, dip in egg wash, then press again in flour, squeezing to form ridges. Set on a rack for 5 minutes; this ‘sets’ the coating so it won’t blow off in the fryer.
- Heat the oil to 350°F (177°C) — about 8 minutes: In a heavy pot or Dutch oven, pour in 6 cups of oil (it should reach at least 1 1/2 inches deep). Warm over medium-high until an instant-read thermometer reads 350°F (177°C). A pinch of flour should sizzle on contact.
- Fry the chicken (about 8 minutes total): Gently lower the fillets into the oil, spacing them so they don’t touch. Fry 3–4 minutes per side until deep golden, the bubbling calms slightly, and the internal temperature hits 165°F (74°C). Adjust heat to keep the oil between 325–350°F (163–177°C).
- Drain and rest (5 minutes): Transfer to a wire rack set over a sheet pan. Lightly season with a pinch of salt while hot. Rest for 5 minutes so juices settle and the crust firms. If needed, keep warm in a 200°F (95°C) oven.
- Toast the buns (about 4 minutes): Split buns and butter the cut sides. Toast cut-side down in a skillet over medium heat until golden at the edges—about 4 minutes total. You’re looking for a gentle crisp that resists sogginess.
- Assemble: Spread peppery mayo on both bun halves. Add a crispy chicken fillet, then pickle chips. Cap with the top bun, pressing lightly to marry textures without crushing the crust.
- Serve immediately: The ideal sandwich should smell of warm spices and toasty butter, with a glassy, ridged crust that crackles under the first bite.
Notes
Chef’s Tips
- Thighs vs. breasts: Boneless thighs are extra-juicy and forgiving; cook time is similar. Pound to 1/2 inch for even frying.
- Craggy crust trick: After the first flour dip, dip only half the fillet in egg wash, then back in flour. The contrast creates dramatic ridges.
- Umami boost: A tiny pinch of MSG in the dredge (about 1/4 tsp) adds that unmistakable savory depth.
- Gluten-free: Use a cup-for-cup gluten-free flour blend and replace cornstarch with potato starch for superb crispness.
- Spicy version: Double the cayenne in the dredge and add extra hot sauce to the mayo.
- Oil care: Fry in clean, fresh oil and skim crumbs between batches to prevent bitterness.
- Air fryer option: Spray dredged fillets lightly with oil. Cook at 400°F (205°C) for 10–12 minutes, flipping halfway, until 165°F (74°C). Crust is slightly lighter but still crisp.
- Oven-fried option: Set a rack over a sheet pan, brush fillets with oil, and bake at 425°F (220°C) for 18–22 minutes until golden and 165°F (74°C).
Serving Suggestions
- Plating: Present in a parchment-lined basket or on a warm plate. Angle-cut the sandwich to showcase the juicy interior and craggy crust.
- Garnish: Extra pickle chips, a sprinkle of flaky salt on the crust, and a dab of sauce beside for dipping.
- Perfect partners: Crinkle-cut fries, creamy coleslaw, or tangy vinegar slaw. Drink with sweet tea, a crisp lager, or lemonade.
- Visual cues: The bun should be glossy and lightly browned, the chicken deep golden with sharp ridges, and steam fragrant with pepper and garlic when cut.
Culinary Context
This sandwich nods to the American Southern tradition of buttermilk-fried chicken—translated by fast-food culture into a craveable classic. The ‘Crispy Colonel’ became beloved for its shattering crust, bright pickles, and simple, peppery sauce. My version leans on professional technique—lightened dredge, temperature control, and resting—to achieve restaurant-level texture at home.Optional Advanced Instructions
- Make-ahead: Brine chicken up to 12 hours. Sauce keeps 3 days refrigerated.
- Staging: Dredge fillets and rest on a rack for up to 20 minutes before frying for an even better set crust.
- Batter alternative: For a thinner shell, whisk 1/2 cup buttermilk into 1 cup flour to make a loose batter; dip and fry. Texture will be smoother, less craggy.
Timing
- Prep Time: 1 hour 10 minutes (includes 45-minute brine)
- Cook Time: 25 minutes (oil preheat ~8 min, fry ~8 min, toast ~4 min, rest ~5 min)
- Total Time: 1 hour 35 minutes

Frequently asked questions
Can I use chicken thighs instead of a breast fillet?
Yes, and boneless skinless thighs actually stay juicier if you overcook them slightly. Pound them to an even thickness around ¾ inch so they cook at the same rate as a breast, and still verify 165°F internal before serving.
What can I use instead of hot sauce in the brine if I don’t have any?
A teaspoon of white vinegar plus a pinch of cayenne does the same job — it adds a little acid and background heat without changing the flavor profile much. The brine’s main work is tenderizing, so the exact hot sauce brand matters less than having some acid in there.
Can I air-fry this instead of deep-frying?
You can, but the crust will be noticeably thinner and less craggy — the circulating air dries the coating before it can puff and set the way hot oil does. If you go that route, spray the dredged chicken generously with neutral oil, cook at 390°F for about 18–20 minutes flipping once, and confirm 165°F internal; expect a crispier-but-flatter result rather than the thick, ridged crust the recipe is going for.
