A Spicy Cajun Crispy Chicken Sandwich that will give any fast food restaurant a run for its money! With a little added heat from the Cajun spices, Louisiana Hot Sauce, and Sriracha, this double-stacked fried chicken sandwich recipe will leave you fulfilled and satisfied.

Spicy Cajun Chicken Sandwich

I’ll be honest. When the craze around Popeye’s Buttermilk Fried Chicken Sandwich came to an end, I knew everyone would be sharing their version of a homemade crispy chicken sandwich. And because I too believe you can make a better recipe in the comforts of your home, I’m here to share my twist.

With my version, I kept things simple and kicked it up a notch with more flavor and spice. You still get that tasty buttermilk crust and tender chicken, but I’ve also added a homemade honey-mustard-BBQ sauce that was inspired by the infamous dipping sauce at Chick-fil-a.

Disclaimer: If you aren’t up for the double crispy chicken sandwich challenge you can easily downsize to a single chicken breast. Your secret will be safe with me.

So let’s jump right into this recipe.

Ingredients you’ll need to make my crispy fried chicken sandwich:

  • Organic boneless chicken breasts because it’s the highlight of this recipe.
  • I went with pretzel buns for my sandwich buns. They have that soft and chewy texture on the inside with a golden brown outside. Bun perfection.
  • The marinade is one of the most important steps for this recipe. Eggs, buttermilk (of course), Louisiana Hot Sauce, Sriracha sauce, black pepper, and paprika make up the spicy marinade.
  • To coat the chicken, I season my flour with cornstarch, Creole seasoning, oregano, garlic powder, thyme, cumin, onion powder, and Himalayan salt.
  • And the homemade “Chick-fil-a” sauce copycat is an easy combination of mayo, barbecue sauce, honey, yellow mustard, black pepper, garlic powder, and oregano.

Why use a buttermilk marinade?

Great question! That tender chicken you love so much. Marinade. The extra crispy exterior crust. Marinade. That seasoned chicken breast that just gets better with every bite. You guessed it, marinade.

First, buttermilk is slightly acidic, which means it is an ideal ingredient to tenderize the chicken. Buttermilk basically acts as a brine and enhances the texture, flavor, and moisture. On top of that, it allows the flour to coat and sticks to the chicken giving you that crunch you want.

Making a Crispy Chicken Sandwich:

Split and cut each chicken breast in half. I find that splitting your chicken breast allows the chicken to cook evenly and keeps you from overcooking it — no one wants dry chicken.

Place your chicken to the side and let’s work on the marinade.

Splitting and cutting chicken breast for the spicy Cajun crispy chicken sandwich

Combine your eggs, buttermilk, hot sauce, sriracha, black pepper, and paprika in a bowl. You’ll place your chicken in the marinade and refrigerate from at least 1 hour.

It won’t hurt if you marinate the chicken for a longer period of time. I have been known to marinate meats up to 8 hours and sometimes overnight.

Dipping chicken breast in buttermilk marinade

When the chicken has been soaking for long enough, you’ll want to season the flour that will coat the chicken. Combine flour, cornstarch, and remaining chicken seasonings into a large zip lock bag. Using a zip lock bag makes this process much easier. You can dredge all the chicken at one time and shake it once. Simple.

Add your cooking oil to the medium-heated pan. Once the oil has reached the appropriate temperature, pan-fry each chicken breast piece for 3 to 4 minutes on each side. You’ll want to adjust the frying time depending on how thick your chicken breast is.

Once the chicken is done, you can quickly make your sauce. Feel free to make this ahead of time.

Because choosing the bread for any sandwich is an important decision, I chose to use pretzel buns with this recipe simply because of the buttery flavor and soft texture.

Place fried chicken breast between your pretzel buns and add a sliced tomato (on the top or the bottom). Isn’t it interesting that depending on where you grew up you place your tomato, lettuce, and pickles on the bottom or top of your chicken breast or hamburger? #whoknew

The finishing touch is the Honey Mayo BBQ “secret sauce” added to the top before taking your first bite.
