What You’ll Need
- Chicken: 2 medium boneless, skinless chicken thighs (or 1 large breast, butterflied and pounded)
- Buttermilk marinade: 1 cup buttermilk, 1 teaspoon salt, 1 teaspoon garlic powder, 1/2 teaspoon black pepper, 1/2 teaspoon paprika
- Breading: 1 cup all-purpose flour, 1/3 cup cornstarch, 1 teaspoon salt, 1 teaspoon paprika, 1/2 teaspoon garlic powder, 1/2 teaspoon onion powder, 1/2 teaspoon black pepper
- Egg wash (optional but helpful): 1 egg, 2 tablespoons water
- Oil for frying: Neutral oil like canola or peanut oil (about 2–3 cups for shallow frying)
- Buns: 2 soft burger buns or potato rolls
- Lettuce: 1 cup shredded iceberg or romaine
- Pickles (optional but great): 6–8 thin dill pickle slices
Garlic Mayo:
- 1/2 cup mayonnaise
- 2–3 garlic cloves, very finely minced or grated
- 1 teaspoon lemon juice
- 1/2 teaspoon Dijon mustard
- 1/4 teaspoon sugar
- Pinch of salt and black pepper
Instructions
- Pound and prep the chicken: If using a breast, slice it horizontally to make two cutlets. Place chicken between plastic or parchment and gently pound to about 1/2-inch thickness so it cooks evenly.
- Marinate: In a bowl, mix buttermilk with salt, garlic powder, pepper, and paprika. Add chicken and coat well. Cover and chill for at least 30 minutes, ideally 2–4 hours. Overnight is fine.
- Make the garlic mayo: Stir together mayo, minced garlic, lemon juice, Dijon, sugar, salt, and pepper. Taste and adjust—add more lemon for brightness or a pinch more sugar for balance. Chill until serving.
- Set up breading station: In one shallow bowl, whisk egg and water. In another, mix flour, cornstarch, salt, paprika, garlic powder, onion powder, and black pepper.
- Bread the chicken: Let excess buttermilk drip off. Dip each piece in the flour mix, then egg wash, then back into the flour. Press firmly to create a craggy coating. Place on a wire rack for 5 minutes to set.
- Heat the oil: Add oil to a heavy skillet to about 1/2 inch depth. Heat to 325–350°F (medium-high). If you don’t have a thermometer, a small pinch of flour should sizzle on contact.
- Fry the chicken: Cook 3–4 minutes per side until golden brown and the internal temperature hits 165°F. Adjust heat as needed to avoid burning. Move to a clean rack to drain; sprinkle with a pinch of salt while hot.
- Toast the buns: In a dry skillet or with a little butter, toast the cut sides of the buns until lightly golden. This keeps them from getting soggy.
- Assemble: Spread garlic mayo on both the top and bottom buns. Add shredded lettuce to the bottom bun, top with the crispy chicken, then add pickles if using. Cap with the top bun and press gently.
- Serve: Enjoy immediately while the chicken is still crisp and the bun is warm.
How to Store
- Cooked chicken: Cool completely, then store in an airtight container in the fridge for up to 3 days. Reheat in a 375°F oven or air fryer for 8–10 minutes to re-crisp.
- Garlic mayo: Keep covered in the fridge for up to 4 days. Stir before using.
- Buns and lettuce: Store at room temp (buns) or refrigerated and dry (lettuce).Assemble just before eating to keep everything fresh.
- Freezing: Freeze cooked chicken cutlets on a sheet tray, then bag and freeze for up to 2 months. Reheat from frozen in a 375–400°F oven or air fryer until hot and crisp.
Health Benefits
- Protein-rich: Chicken provides lean protein that supports muscle repair and keeps you full longer.
- Customizable fat and sodium: You control the salt and can choose a lighter mayo or Greek yogurt blend to reduce saturated fat.
- Garlic perks: Garlic contains compounds like allicin, which may support heart health and have antimicrobial properties.
- Fiber add-ons: Using a whole wheat bun and adding extra lettuce or tomato can boost fiber and micronutrients.
What Not to Do
- Don’t skip the rest after breading: Letting the coating sit for a few minutes helps it adhere and crisp properly.
- Don’t fry in oil that’s too cool or too hot: Cool oil makes soggy chicken; overly hot oil burns the crust before the inside cooks.
- Don’t overload the pan: Crowding drops the temperature and ruins the crunch. Fry in batches if needed.
- Don’t build the sandwich too early: Assemble just before serving so the bun stays fresh and the chicken stays crisp.
- Don’t overdo the garlic: Raw garlic is strong. Taste the mayo and adjust—more isn’t always better.
Variations You Can Try
- Grilled version: Skip the breading. Marinate, then grill the chicken over medium heat, 4–5 minutes per side. Still use the garlic mayo for flavor.
- Spicy kick: Add cayenne to the breading and a dash of hot sauce to the mayo. Top with pickled jalapeños.
- Extra-crispy: Double-dredge by repeating flour → egg → flour once more. Adds a thicker crust.
- Lighter mayo: Mix half mayo with half plain Greek yogurt. Add a touch more lemon and a drizzle of olive oil to round it out.
- Deluxe toppings: Add tomato slices, red onion, or a slice of mild cheese like Monterey Jack.
- Herb twist: Stir chopped parsley or chives into the garlic mayo for a fresher profile.
FAQ
Can I use chicken breasts instead of thighs?
Yes.
Butterfly the breast and pound it to even thickness so it cooks quickly and stays juicy. Don’t skip the marinade, which helps tenderize and season the meat.
What if I don’t have buttermilk?
Make a quick substitute: mix 1 cup milk with 1 tablespoon lemon juice or white vinegar. Let it sit for 5 minutes, then use as directed.
Can I air fry the chicken?
Yes.
Spray both sides with oil and air fry at 375°F for 10–14 minutes, flipping halfway, until the crust is crisp and the internal temp hits 165°F. The texture will be slightly different but still delicious.
How garlicky is the mayo?
Moderately strong. Start with two cloves, taste, and add a third if you want more punch.
Finely grating the garlic makes it stronger than mincing.
What buns work best?
Soft potato rolls or classic burger buns. Brioche is tasty but can be a bit sweet; toast lightly either way to prevent sogginess.
Can I bake the chicken instead of frying?
You can. Place breaded chicken on a wire rack set over a sheet pan, spray with oil, and bake at 400°F for 18–22 minutes, flipping once.
It won’t be as shatteringly crisp as frying, but it’s still good.
How do I keep the crust from falling off?
Pat the chicken dry before marinating, press the flour coating firmly, and rest the breaded pieces for a few minutes before frying. Avoid flipping too often and use tongs gently.
Is the sugar in the mayo necessary?
Just a pinch helps balance the garlic and lemon. You can skip it, but the sauce will taste a bit sharper.
What oil should I use?
Use a neutral, high-heat oil like canola, peanut, or sunflower.
Avoid olive oil for frying—it can smoke and add bitterness.
Can I make the mayo ahead?
Yes, up to 4 days in advance. The garlic flavor actually blooms over time, so taste before serving and add lemon if needed.
