Ingredients
- 2 boneless, skinless chicken breasts
- 1 cup buttermilk
- 1 tablespoon Cajun seasoning
- 1 cup all-purpose flour
- 1 teaspoon paprika
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- 1/2 teaspoon salt
- 1/2 teaspoon black pepper
- Vegetable oil for frying
- 1/2 cup mayonnaise
- 2 cloves garlic, minced
- 1 tablespoon lemon juice
- 1/2 teaspoon salt (for aioli)
- 1/4 teaspoon black pepper (for aioli)
- 4 brioche buns
- Leafy romaine lettuce
- Sliced tomatoes
Instructions
- Step 1: In a bowl, combine the buttermilk and Cajun seasoning. Add the chicken breasts, cover, and marinate in the refrigerator for at least 1 hour.
- Step 2: In a separate bowl, mix the flour, paprika, garlic powder, onion powder, salt, and black pepper.
- Step 3: Heat vegetable oil in a deep skillet over medium-high heat until it reaches about 350°F (175°C).
- Step 4: Remove the chicken from the buttermilk, letting excess drip off, then dredge each breast evenly in the seasoned flour mixture.
- Step 5: Carefully place the chicken in the hot oil and fry for 5-7 minutes on each side, or until golden brown and cooked through. The internal temperature should reach 165°F (74°C).
- Step 6: While the chicken fries, prepare the garlic aioli by mixing mayonnaise, minced garlic, lemon juice, salt, and pepper in a small bowl.
- Step 7: Once cooked, drain the chicken on paper towels and let it rest for a few minutes.
- Step 8: To assemble, spread garlic aioli on the bottom half of each brioche bun. Add a layer of lettuce, a slice of tomato, and top with the crispy chicken. Place the other half of the bun on top and serve immediately.
Tips & Variations
- For extra crispiness, double-dip the chicken by dipping it back into the buttermilk and then the flour mixture before frying.
- Substitute the brioche buns with ciabatta or potato rolls for a different texture.
- Add pickles or sliced jalapeños for an extra kick.
- If you don’t have buttermilk, mix 1 cup milk with 1 tablespoon lemon juice or vinegar and let it sit for 5 minutes to substitute.
Storage
Store leftover chicken and aioli separately in airtight containers in the refrigerator for up to 3 days. Reheat the chicken in a preheated oven at 350°F (175°C) for 10-15 minutes to maintain crispiness. Avoid microwaving to prevent sogginess. Assemble sandwiches just before serving.

- Yield: 4 sandwiches 1x
Description

This sandwich delivers a perfect balance of spicy, tangy, and savory flavors with a delightful crunch.
Ingredients
For the Chicken:
- 2 boneless, skinless chicken breasts
- 1 cup buttermilk
- 1 tablespoon Cajun seasoning
- 1 cup all-purpose flour
- 1 teaspoon paprika
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- 1/2 teaspoon salt
- 1/2 teaspoon black pepper
- Vegetable oil for frying
For the Garlic Aioli:
- 1/2 cup mayonnaise
- 2 cloves garlic, minced
- 1 tablespoon lemon juice
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
For Assembly:
- 4 brioche buns
- Leafy romaine lettuce
- Sliced tomatoes
Instructions
- Marinate the Chicken: In a bowl, combine buttermilk and Cajun seasoning. Add the chicken breasts, cover, and refrigerate for at least 1 hour to allow the flavors to infuse and tenderize the meat.
- Prepare the Flour Mixture: In a separate bowl, mix together the all-purpose flour, paprika, garlic powder, onion powder, salt, and black pepper to create a flavorful coating for the chicken.
- Heat the Oil: Pour vegetable oil into a deep skillet to a depth suitable for frying and heat it over medium-high heat until it reaches about 350°F, the ideal temperature for crispy frying.
- Coat the Chicken: Remove the marinated chicken from the buttermilk, allowing any excess to drip off. Dredge each piece thoroughly in the seasoned flour mixture, making sure they are evenly coated on all sides.
- Fry the Chicken: Carefully place the coated chicken breasts in the hot oil. Fry for 5–7 minutes on each side, or until the chicken is golden brown and fully cooked with an internal temperature of 165°F. Use a thermometer to ensure safety.
- Make the Garlic Aioli: While the chicken fries, combine the mayonnaise, minced garlic, lemon juice, salt, and black pepper in a small bowl. Stir well to create a smooth and tangy aioli sauce.
- Drain and Rest the Chicken: Once cooked, remove the chicken from the oil and place on paper towels to drain excess oil. Let it rest for a few minutes so the juices settle and the coating remains crispy.
- Assemble the Sandwich: Spread a generous layer of garlic aioli on the bottom halves of the brioche buns. Add leafy romaine lettuce and a slice of tomato on top of the aioli, then place the crispy Cajun chicken breast. Top with the bun’s top halves and serve immediately to enjoy the sandwich at its best.
Notes
- For extra heat, add cayenne pepper to the flour mixture.
- Ensure the oil maintains 350°F for perfect frying; too hot may burn the coating, too cool will absorb excess oil.
- Use a meat thermometer to confirm the internal temperature reaches 165°F for food safety.
- Letting the chicken rest after frying helps maintain juiciness and crispiness.
- Can substitute romaine with iceberg lettuce or mixed greens as preferred.
- Brioche buns add sweetness and softness, but any sandwich bun can be used.
- Make the garlic aioli ahead and refrigerate to deepen flavors.
