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 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 together 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.
Step 4: Remove chicken from buttermilk, letting the excess drip off, then dredge each breast in the flour mixture, coating evenly.
Step 5: Carefully place the chicken in the hot oil and fry for 5-7 minutes on each side until golden brown and cooked through (internal temperature should reach 165°F).
Step 6: While the chicken is frying, 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, then add lettuce, a slice of tomato, and the crispy chicken. Top with the other half of the bun and serve immediately.

Tips & Variations

For extra heat, add a pinch of cayenne pepper to the flour mixture or aioli.
Use smoked paprika instead of regular paprika for a deeper flavor.
Try substituting romaine with arugula for a peppery bite.
For a lighter option, bake the coated chicken at 400°F for 20-25 minutes instead of frying.

Storage

Store leftover chicken in an airtight container in the refrigerator for up to 2 days. To reheat, warm gently in an oven at 350°F for about 10 minutes to maintain crispiness. Avoid microwaving to prevent sogginess. Assemble sandwiches fresh before serving.

FAQs

Can I use frozen chicken breasts for this recipe?

It’s best to use fresh or fully thawed chicken breasts for even cooking and the best texture. If using frozen, thaw completely in the refrigerator before marinating.

What can I substitute for buttermilk if I don’t have any?

You can make a buttermilk substitute by mixing 1 cup of milk with 1 tablespoon of lemon juice or white vinegar. Let it sit for 5 minutes before using.
