- 1 tablespoon lemon juice
- 1/2 teaspoon salt (for aioli)
- 1/4 teaspoon black pepper (for aioli)

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.
- Step 4: Remove chicken from the buttermilk, letting excess drip off, then dredge each piece in the flour mixture, ensuring an even coating.
- 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 (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 the chicken is cooked, drain it on paper towels and let rest for a few minutes.
- Step 8: To assemble, spread garlic aioli on the bottom half of each brioche bun, add lettuce, a slice of tomato, and the crispy chicken. Top with the other half of the bun and serve immediately.
Tips & Variations
- For an extra spicy kick, add cayenne pepper to the flour mixture or sprinkle on the aioli.
- If you prefer a lighter option, bake the coated chicken at 400°F for 20-25 minutes instead of frying.
- Try swapping romaine for arugula or adding pickles for extra crunch and tang.
- Use homemade brioche buns or toasted sandwich rolls for additional flavor and texture.
Storage
Store leftover chicken sandwiches separately wrapped in the refrigerator for up to 2 days. To reheat, warm the chicken in a skillet or oven until heated through, then assemble the sandwich fresh to keep the buns from getting soggy. Garlic aioli can be stored in an airtight container in the fridge for up to 3 days.

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

- 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 chicken breasts, cover, and marinate in the refrigerator for at least 1 hour to infuse flavor and tenderize the meat.
- Prepare the Flour Coating: In a separate bowl, mix together flour, paprika, garlic powder, onion powder, salt, and black pepper, creating the flavorful coating for the chicken.
- Heat the Oil: Heat vegetable oil in a deep skillet over medium-high heat to about 350°F, ensuring the oil is hot enough for frying.
- Coat the Chicken: Remove chicken from the buttermilk marinade, allowing excess to drip off. Dredge each breast in the seasoned flour mixture, making sure to coat evenly on all sides for that crispy crust.
- Fry the Chicken: Carefully place the coated chicken breasts into the hot oil. Fry for 5-7 minutes on each side, or until they turn golden brown and reach an internal temperature of 165°F, ensuring they are fully cooked and juicy.
- Make the Garlic Aioli: While the chicken fries, combine mayonnaise, minced garlic, lemon juice, salt, and black pepper in a small bowl. Stir well to create a creamy, flavorful aioli.
- Rest the Chicken: Once cooked, transfer the chicken to paper towels to drain excess oil and let it rest for a few minutes to retain juiciness.
- Assemble the Sandwich: Spread garlic aioli on the bottom halves of the brioche buns. Layer with leafy romaine lettuce, a slice of tomato, and the crispy chicken breast. Top with the bun halves and serve immediately for the best taste and texture.
Notes
- Marinating the chicken overnight enhances flavor and tenderness even more.
- Use a meat thermometer to ensure the chicken is safely cooked to 165°F.
- For extra crispiness, double dredge the chicken by dipping back into the buttermilk and flour mixture before frying.
- Substitute brioche buns with potato buns or ciabatta for a variation in texture.
- The garlic aioli can be made ahead and stored in the fridge for up to 2 days.
