If you love that iconic hearty chicken sandwich (you know the one!) but want a healthier version you can feel good about making at home, this one’s for you. This crispy (yet lighter) chicken sammie hits all the nostalgic notes—juicy chicken, tender bun, briny pickles, and a creamy mustardy sauce—without the deep fryer or mystery ingredients. It’s my kind of comfort food: easy to make, super delicious and smartly upgraded.

This version is oven-baked, has fewer calories, and is much healthier than the classic fried rendition. I stay true to the signature dish by piling on all the toppings. I typically use yellow mustard (because that’s what they use at Chick-fil-A) but you can swap in spicy brown or Dijon. As for the BBQ sauce? Use your favorite jarred version—sweet, smoky, spicy—because as I like to say, “YOU are the boss of your sauce!”

If crispy chicken is your love language, don’t stop here. My Crispy Chicken Tenders will also hit the spot—golden, crunchy, and endlessly dippable (try dipping’ them with my Creamy Dill Pickle RanchHoney Mustard SauceChili Lime CremaBBQ MustardSpicy or Creamy Ketchup).

And these Pecan-Crusted Chicken Tenders bring a slightly nutty crunch that feels special enough for guests but easy enough for a Tuesday…or Wednesday. Same yummy satisfaction, two very different and equally crave-able vibes!

Chick-fil-A Copycat: Chicken Sandwich with Tangy Mustard Sauce

Skip the food court and meet me in the kitchen for my copycat version of a fast food favorite: the crispy chicken sandwich!
Yield: 4 sandwiches
Prep Time: 15 minutes
Cook Time: 20 minutes
Marinade Time: 30 minutes
Total Time: 1 hour 5 minutes

Ingredients
 

Chicken Sandwich

  • 2 skinless chicken breasts, 1 pound total
  • 1 cup pickle juice*
  • 1 large egg
  • 2 tablespoons light mayonnaise
  • 1 cup breadcrumbs, preferably whole grain**
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • 1 teaspoon paprika
  • ¾ teaspoon kosher salt, more for sprinkling on top
  • ½ teaspoon ground black pepper
  • 4 whole-grain buns
  • Lettuce, sliced tomato, pickles

Tangy mustard sauce (makes ½ cup)

  • ¼ cup light mayo
  • 2 tablespoons BBQ sauce
  • 1 tablespoon yellow mustard
  • 1 teaspoon lemon juice
  • 1 to 2 teaspoons honey, optional
Ingredient Details to Know
* Can use low-fat buttermilk
** Can use gluten-free or panko breadcrumbs

Instructions
 

Marinating:

  • Place chicken breasts on a cutting board between large sheets of parchment or wax paper. Using a meat tenderizer or soup can, pound each chicken breast until it’s no more than ½-inch thick all around.
  • Cut each piece into two, for a total of 4 pieces. Place in a plastic bag or bowl with pickle juice and marinate in the fridge for at least 30 minutes to overnight.
  • When chicken is done marinating, preheat oven to 450℉ and liberally mist a baking sheet with nonstick oil spray or line with aluminum foil. *If you have a wire baking rack, I recommend using it on top on the sheets for crispier chicken. Set aside.

Set up your dredging station:

  • In one shallow wide bowl, add the egg and mayo and mix until well combined.
  • In a second shallow wide bowl, add the breadcrumbs and seasonings and mix until well combined. One at a time, lift each piece of chicken out of the pickle juice and shake off excess liquid. Submerge into the egg-mayo.
  • Then, place into the breadcrumbs bowl and pat all over to fully coat. Place on the prepared baking sheet (or on wire rack, if using). Mist the breaded chicken tops with oil spray and lightly sprinkle on some additional kosher salt.
  • Bake in the oven for about 20 minutes or until chicken reaches an internal temp of 165 and the tops are crispy brown.
  • While the chicken is cooking, make the sauce by mixing all of the ingredients together in a small bowl (mayo, BBQ sauce, mustard, lemon juice and optional honey).
  • Remove chicken from oven and build your sandwich: layer your bottom bun with pickles, lettuce, tomato and then your chicken cutlet. Top with tangy mustard sauce and dig in!

Notes

Air Fryer Option:Preheat air fryer to 375°F. Lightly spray the basket with oil. Arrange breaded chicken cutlets in a single layer and mist the tops with oil. Air fry for 10 minutes, flip, mist again, and cook another 5–7 minutes, or until golden, crispy, and the chicken reaches an internal temperature of 165°F.Timing may vary slightly depending on air fryer model and cutlet thickness.
A serving is 1 full sandwich with toppings and bun. Add 20 calories for each tablespoon of Tangy Mustard Sauce.
