¼ tsp cumin 0.5 g
¼ tsp black pepper 0.5 g

½ tsp garlic powder 1.5 g

Slaw

2 cups shredded cabbage 120 g
¼ cup shredded carrot 30 g
2 tbsp mayo 30 g
2 tsp lemon juice 10 ml
½ tsp sugar 2 g
Salt to taste, added just before serving

Assembly

4 brioche or potato buns
Dill pickle slices
6–8 cups neutral oil for frying 1.5–2 quarts / ~1.4–1.9 L

Instructions

Salt the chicken evenly with kosher salt and let it rest for 30 minutes to dry brine.
In a bowl, mix the buttermilk, harissa, smoked paprika, garlic powder, cumin, black pepper, and sugar. Add the chicken and marinate in the refrigerator for at least 4 hours or up to 24 hours.
Remove the chicken from the refrigerator and let it sit at room temperature for 15–20 minutes before frying.
Heat oil in a heavy pot to 350–355°F. Maintain oil temperature between 325–345°F while frying, allowing it to return to temperature between batches.
In a separate bowl, mix flour, cornstarch, baking powder, salt, paprika, garlic powder, onion powder, and cayenne.
Remove chicken from marinade, letting excess drip off. Dredge thoroughly in the flour mixture, pressing firmly for 5–10 seconds per side. Sprinkle 1–2 tablespoons of marinade into the flour mixture and toss lightly to create craggy bits, then re-press the chicken into the dredge.
Fry 1–2 pieces at a time for 5–6 minutes total, flipping once after 2–3 minutes when the crust is set. Cook until golden brown and the internal temperature reaches 165°F.
Transfer to a wire rack and rest for 3–5 minutes. Lightly sprinkle with fine salt while hot if desired.
In a small bowl, mix together the harissa mayo ingredients.
In another bowl, combine cabbage, carrot, mayo, lemon juice, and sugar. Add salt just before assembling to prevent excess moisture.
Toast buns until lightly golden and slightly crisp. Spread harissa mayo on the bottom bun, add fried chicken, pickles, slaw, and a light drizzle of sauce. Top with the bun and serve immediately.

Notes

🌶️ Getting the Crispiest Harissa Fried Chicken

For an ultra crispy harissa fried chicken sandwich, use a combination of flour, cornstarch, and a small amount of baking powder. This creates a light, airy crust that fries up golden and crunchy. When dredging, press the flour mixture firmly onto the chicken and create dry, craggy bits—this is what gives that signature crispy fried chicken texture.

🌡️ Oil Temperature for Perfect Fried Chicken

Maintaining the correct oil temperature is essential for a crispy chicken sandwich that isn’t greasy. Heat oil to 350–355°F before frying and keep it between 325–345°F while cooking. If the oil drops below 320°F, pause and allow it to return to temperature before adding more chicken.

🧂 Salt Balance for Best Flavor

This recipe uses a dry brine to season the chicken all the way through, which creates a juicy and flavorful interior. Using Diamond Crystal kosher salt ensures consistent seasoning. If using Morton kosher salt, reduce the amount slightly since it is denser and saltier by volume.

🥬 How to Keep Slaw Crisp (No Soggy Sandwiches)

To prevent a soggy fried chicken sandwich, add salt to the slaw right before assembling. You can also squeeze excess moisture from the cabbage for an extra crisp texture. This keeps the sandwich balanced with a fresh, crunchy bite.

🍞 Toasting Buns for Texture

Lightly toast brioche or potato buns until golden and slightly crisp on the cut side. This creates a barrier that helps prevent the sandwich from becoming soggy once the fried chicken and sauce are added.

🔥 Harissa Flavor Tips

Harissa paste adds smoky, slightly spicy depth to this sandwich. If you prefer a milder flavor, reduce the amount in the sauce. For a spicier harissa chicken sandwich, add extra harissa or a pinch of cayenne to the dredge.

🍗 Even Cooking Every Time

Pound the chicken to an even ½ inch thickness so it cooks evenly. This ensures the coating turns golden brown at the same time the inside reaches 165°F, preventing undercooked centers or overcooked crust.

🧊 Make Ahead Tips

You can marinate the chicken up to 24 hours in advance for deeper flavor. The slaw and harissa mayo can also be prepared ahead and stored in the refrigerator until ready to assemble.

🚀 Pro Tip for Restaurant-Quality Results

For the best fried chicken sandwich, lightly sprinkle fine salt over the chicken immediately after frying. This enhances flavor and gives the sandwich that professional, restaurant-quality finish.
