- Step 3: Heat vegetable oil in a deep skillet over medium-high heat until it reaches about 350°F.
- Step 4: Remove the chicken from the buttermilk, letting the excess drip off, then dredge each breast in the flour mixture, coating evenly.
- Step 5: Carefully place the coated chicken in the hot oil and fry for 5-7 minutes per 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 black 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 the sandwich, 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 bun half and serve immediately.
Tips & Variations
- For extra heat, add cayenne pepper to the flour mixture or swap romaine for peppery arugula.
- Use chicken thighs instead of breasts for a juicier sandwich.
- Try adding pickles or sliced red onions for added crunch and tang.
- Buttermilk marinating helps tenderize the chicken; don’t skip this step if time allows.
Storage
Store leftover chicken and aioli separately in airtight containers in the refrigerator for up to 2 days. Reheat the chicken in the oven or air fryer to keep the coating crispy. Assemble the sandwich fresh before serving to maintain the best texture.
How to Serve
Serve this delicious recipe with your favorite sides.
FAQs
Can I use regular milk instead of buttermilk?
Regular milk can be used in a pinch, but it won’t tenderize the chicken as effectively. To mimic buttermilk, add 1 tablespoon of lemon juice or vinegar per cup of milk and let it sit for 5 minutes before using.
What oil is best for frying the chicken?
Vegetable oil or canola oil works best because they have a high smoke point and neutral flavor, which ensures even frying without burning or altering the taste.

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 (about 2 cups)
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 (4-8 leaves)
- Sliced tomatoes (4 slices)
Instructions
- Marinate the Chicken: In a bowl, combine the buttermilk and Cajun seasoning thoroughly. Place the chicken breasts into the mixture, cover the bowl, and refrigerate for at least 1 hour to let the flavors penetrate and tenderize the meat.
- Prepare the Flour Mixture: In a separate bowl, mix together all-purpose flour, paprika, garlic powder, onion powder, salt, and black pepper. This seasoned flour will create the crispy coating on the chicken.
- Heat the Oil: Pour vegetable oil into a deep skillet to a depth suitable for frying, and heat over medium-high heat until it reaches about 350°F (175°C), optimal for frying chicken to a golden crisp.
- Dredge the Chicken: Remove each chicken breast from the buttermilk marinade, letting excess drip off. Then, thoroughly coat it in the seasoned flour mixture, pressing lightly to ensure the coating adheres evenly.
- Fry the Chicken: Carefully place the floured chicken breasts into the hot oil. Fry each side for 5-7 minutes, turning once, until the coating is golden brown and the internal temperature reaches 165°F (74°C), ensuring the chicken is 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. Mix well until smooth to create a tangy, garlicky sauce.
- Drain and Rest: Once cooked, transfer the chicken to a paper towel-lined plate to drain excess oil, then let it rest for a few minutes to retain juiciness.
- Assemble the Sandwiches: Spread a generous layer of garlic aioli on the bottom half of each brioche bun. Layer with romaine lettuce leaves, a slice of tomato, and the crispy chicken breast. Top with the remaining bun halves and serve immediately for the best texture and flavor experience.
Notes
- Marinating the chicken for longer than 1 hour, up to overnight, will enhance the flavor and tenderness.
- Maintain the oil temperature at 350°F while frying to ensure a crispy coating without absorbing excess oil.
- Use a meat thermometer to confirm chicken is fully cooked to avoid under or overcooking.
- Brioche buns add a rich sweetness that complements the spicy chicken, but you can substitute with your favorite burger buns.
- If you prefer less heat, reduce or omit the Cajun seasoning from the marinade.
