List of ingredients

• 4 chicken thighs or 1-inch thick chicken breasts (boneless, skinless)
• 1 and 1/2 cups buttermilk
• 1 large egg
• ⅔ cup hot sauce (Louisiana style)
• 2 cups all-purpose flour
• ⅓ cup cornstarch
• 3 tsp. smoked paprika
• 2 tsp. chili powder
• 2 tsp. cayenne pepper
• 2 tsp. onion powder
• 2 tsp. garlic powder
• ½ tsp. ground mustard
• 2 tsp. kosher salt
• 1 tsp. black pepper
• 2 and 1/2 cups canola oil
• ½ cup buttermilk
• ½ cup sour cream
• ¼ cup mayonnaise
• 1 tsp. apple cider vinegar
• ½ tsp. garlic powder
• ½ tsp. onion powder
• ⅛ tsp. dried mustard
• 1/2 lemon (juiced)
• 1 tbsp. fresh dill (chopped)
• 1 tbsp. fresh chives (chopped)
• pinch salt and pepper
• 4 brioche buns (buttered and grilled on the flat side)
• iceberg lettuce (shredded)
• dill pickle chips

step-by-step instructions

1. Step: Prepare the marinade by whisking together the hot sauce, buttermilk and ground mustard in a medium-sized bowl.
2. Step: Place the chicken thighs or breasts in a casserole dish, and pour the buttermilk mixture over them. Let the chicken marinate in the refrigerator for 1-4 hours, or overnight.
3. Step: Prepare the buttermilk-ranch sauce by whisking together all of the sauce’s wet ingredients with the dry seasonings. Stir in the fresh chives and dill. Set aside, or chill in the refrigerator.
4. Step: Prepare the seasoned coating by whisking together the flour, cornstarch and dry seasonings in a large bowl.
5. Step: Pre-heat the oil to 350°F in a deep-sided dutch oven or large cast iron skillet.
6. Step: Remove the chicken from marinade, shake off any excess marinade and set the chicken aside. Add 1 egg to the bowl of leftover marinade and whisk until the egg is fully disbursed.
7. Step: Dredge each chicken breast/thigh in the seasoned flour, dip once more in the marinade and let the excess marinade drip off, then dredge in flour again.
8. Step: Drop each breast/thigh in the hot oil and fry for 15-18 minutes. Use a digital meat thermometer to measure the internal temperature of the chicken. The temperature needs to register at 170°F for thighs and 165°F for breasts.
9. Step: Assemble the sandwiches in this order: Bottom bun, a thin layer of ranch, a few pickle chips, crispy chicken, another spoonful of ranch, shredded iceberg, a few more pickle chips, top bun.

Successful frying techniques

Maintaining consistent oil temperature

Using a deep-fry thermometer is the most reliable way to ensure your oil remains at 350°F throughout the cooking process. If the temperature drops too low, the crust will absorb oil and become greasy rather than crispy. If it is too high, the outside will burn before the chicken is cooked through to the center.

Selecting the right cooking vessel

A heavy Dutch oven or cast-iron skillet is ideal because these materials retain heat remarkably well. This stability prevents the oil temperature from crashing when you introduce cold chicken pieces. The high sides of a Dutch oven also serve as a protective barrier, minimizing oil splatter around your stove area.

Refining your ranch sauce

Achieving the perfect creamy consistency

The balance between sour cream and mayonnaise is what gives this ranch its signature texture. The sour cream provides a light tang, while the mayonnaise ensures the sauce is thick enough to cling to the chicken without running off the bun. If you prefer a thinner consistency for drizzling, you can stir in an extra tablespoon of buttermilk.

Importance of fresh herbs

Using fresh dill and chives makes a significant difference compared to dried equivalents. Fresh herbs offer a vibrant, aromatic profile that cuts through the richness of the fried chicken. If you find yourself without fresh herbs, ensure you crush your dried herbs between your fingers before adding them to release their remaining essential oils.

Customizing your sandwich

Managing the spice levels

If you prefer a milder sandwich, simply omit the cayenne pepper and reduce the amount of hot sauce in the buttermilk marinade. Conversely, if you enjoy significant heat, you can add an extra half-teaspoon of cayenne to the dredging flour. This allows the heat to hit the palate from both the inside and the outside of the chicken.

Enhancing the bun experience

The brioche bun is structurally superior for this recipe due to its high fat and sugar content, which promotes excellent caramelization. By brushing the cut sides with a small amount of butter and heating them on a flat-top grill, you create a protective toasted surface. This prevents the ranch and juices from soaking into the bread and making it soggy.

Planning ahead and storage

Marination schedule optimization

While 4 hours is the minimum requirement for marinating, allowing the chicken to sit for 24 hours provides the best results. The acidity in the buttermilk has more time to break down the protein fibers, resulting in an exceptionally tender product. Always ensure your chicken is kept in a sealed container in the coldest part of your refrigerator.

Proper reheating methods

To restore the crunch of leftover chicken, avoid the microwave, as it will soften the breading. Instead, place the chicken on a wire rack set over a baking sheet and bake it at 350°F until the exterior is crisp and the center is heated through. This method allows hot air to circulate around the entire piece of chicken.

Frequently asked questions

Why did my coating fall off during frying?

This usually happens if the chicken was too damp before the first dredging or if the oil temperature was not hot enough. Ensure you pat the chicken slightly dry after removing it from the marinade and wait for the oil to fully recover its temperature between batches. Using a wire rack to let the breaded chicken rest for five minutes before frying can also help the coating adhere better.

Can I substitute the chicken thighs for breasts?

Yes, you can easily swap between breasts and thighs depending on your preference for white or dark meat. If using breasts, be sure to pound them to a uniform thickness so they cook evenly throughout. Thighs are generally more forgiving during the frying process due to their higher fat content, which keeps them juicy even if cooked for a minute or two longer.

How do I know the oil is ready without a thermometer?

If you do not have a thermometer, you can test the oil by dropping a tiny pinch of the flour mixture into the pot. If the flour sizzles and bubbles immediately upon hitting the surface, the oil is likely hot enough to begin frying. However, relying on a digital thermometer is still the safest way to ensure your kitchen remains safe and your food cooks correctly.

Is there a way to make this meal healthier?

You can achieve a similar texture by using an air fryer, which significantly reduces the amount of oil required. Simply spray the breaded chicken thoroughly with cooking spray and air fry at 370°F, flipping halfway through. While the texture will be slightly different from deep frying, it remains a delicious way to enjoy the same flavors with less added fat.
