Crispy Chicken Sandwiches (Buttermilk Marinade)

This is is marinated in seasoned buttermilk and deep-fried until it’s crispy and golden brown, topped with a homemade spicy mayo and piled onto a brioche bun. It’s amazing! If you don’t have a deep fryer, it will work just fine in a skillet or Dutch oven.

I hope you love this and it gets added to your dinner recipe rotation. Since it’s basically a giant chicken tender, you can serve it without the bun to your pickiest eaters.

Ingredients and Tools You’ll Need

The standout ingredients in this recipe are the buttermilk and the homemade seasoning blend. If you don’t have buttermilk, I wouldn’t recommend any substitutes. It’s really important for the recipe.

If you have an electric deep fryer you won’t have to deal with splattering oil and temperature monitoring.

How to Make a Buttermilk Fried Chicken Sandwich

Honestly, this isn’t hard. Deep frying can be intimidating, but other than that, this recipe is easy-peasy.

Step One: Make the Seasoning Blend

Start by making your seasoning blend by combining the salt, pepper, paprika, cayenne, and garlic powder in a small bowl.

Step Two: Prep Chicken

Pound your chicken thin with a meat mallet or rolling pin so that it cooks evenly and quickly.

Step Three: Marinate

Scoop out 2 tablespoons of the blend and mix it with two cups of the buttermilk. Place the chicken in the buttermilk and let it marinate. If you have the time, pop the bowl in the fridge for four hours. If you’re in a hurry, leave it on the counter for about thirty minutes.

Step Four: Bread

When it’s time for the next step, start heating up your oil to 360 degrees. (Be careful, and keep an eye on it!) Mix up the flour and a tablespoon of the seasoning blend. Take out the chicken, gently shake it off, and dredge in the flour mixture.

Step Five: Fry

And now we fry! The chicken will take about 8 minutes, and you’ll want to flip it halfway through. It will look quite dark because of the paprika, which can be deceptive, so check to make sure it’s done inside.

Step Six: Drain

Let it drain on paper-towel-lined plates.

Step Seven: Make Sauce and Serve

Mix up the sauce ingredients in a bowl.

Then make your sandwiches. Spread the sauce on both sides of your bun and add your favorite toppings then the chicken. We love them with thinly sliced pickles and shredded lettuce.

Serving & Storing

Serve with some crispy fries, coleslaw, corn on the cob, and some lemonade.

Store any leftover chicken in the fridge for up to 3 days in an airtight container. Don’t stack the pieces directly on top of each other or they’ll get soggy. Put some parchment paper between them. Reheat it in a 375°F oven for about 5-7 minutes to get that crispiness back. Or you can use an air fryer at 350°F for 3-4 minutes.

Keep any leftover sauce covered in the fridge up to a week. You can also keep the marinated chicken in the fridge up to 2 days so you can fry fresh pieces when you need them.

Questions and Troubleshooting

My oil is smoking – help!

Your oil is too hot. Take it off the heat and let it cool to 360°F. Don’t just turn it down and expect it to cool down, remove it.

How do I know when it’s actually done?

Use a meat thermometer! Internal temp should hit 165°F. The outside will look REALLY dark because of that paprika, so don’t go by color alone.

My breading is falling off!

Make sure you shake off excess buttermilk but don’t pat it completely dry. You need some moisture for the flour to stick to. Also, let the breaded chicken sit for 5 minutes before frying.

The oil temperature keeps dropping when I add chicken.

Totally normal! Don’t add all the chicken at once. Do 2-3 pieces max so the temp doesn’t crash.

Instructions
 

  • Make seasoning blend. Combine the seasonings in a small bowl. Set aside. You will use this for all parts of the sandwich.
  • Prepare chicken. Pound chicken cutlets as thin as possible. If you are working with full-sized chicken breasts, slice them in half first.
  • Marinate chicken. Pour buttermilk into a large mixing bowl. Measure out 2 tablespoons of the seasoning mixture and combine with buttermilk, stirring well. Place chicken breasts in buttermilk to marinate, making sure they are fully submerged. Cover and refrigerate for 4 hours, or 30 minutes at room temperature.
  • Bread chicken. In a separate large mixing bowl, combine 1 tablespoon of the seasoning blend with the flour. Remove chicken from the buttermilk marinade, shake off gently, and toss in seasoned flour.
  • Fry. Heat oil in deep, heavy bottomed Dutch oven or electric deep fryer to 360℉. Deep fry for 7-9 minutes at 360℉, turning halfway through. Chicken will appear dark due to the paprika, make sure to check inside for doneness.
  • Drain. Remove to paper towel-lined baking sheet or plate to drain.
  • Make the sauce. Combine sauce ingredients in a small bowl.
  • Assemble. Toast buns if desired and assemble sandwiches with the sauce and your favorite toppings. We like dill pickle and lettuce 😊.
