Gluten-Free Kimchi Brined Fried Chicken Sandwich

This gluten-free fried chicken sandwich comes together with a perfect combination of flavors and a Korean-inspired twist! It will take some advanced preparation, but the flavor is a huge payoff.

The Makings of a Perfect Fried Chicken Sandwich

Fried chicken sandwiches are extremely popular, but what makes a fried chicken sandwich absolutely SING to your tastebuds?

Not only do you expect tender and juicy chicken wrapped in crispy fried goodness, but you also expect some balance. You want the complete package: savory, sour, sweet, spicy… I’m telling you, you can have it ALL!

The fatty breading and buttery biscuit beg for a balance of fresh and luscious veggies. For the vegetable stars in this chicken sandwich, I’ve chosen a carrot slaw and cucumber kimchi (which plays double duty in flavoring your chicken marinade AND as a sandwich topping). The carrot slaw is crunchy and sweet – but it’s not overly carrot-y (that was a concern of mine in recipe development), while the bright acidity from the cucumber kimchi cuts through the fat.

Components of this Fried Chicken Sandwich

I’ve slowly been working my way up to this grand dinner plan as a culmination of several recipes:


To achieve these AMAZING results, you do need to plan ahead. I start the cucumber kimchi two days before my dinner plan goes live – to give enough time for a delicious juice to come together. Then I use that juice on the chicken marinade one day before go-live, so it has plenty of time for the marinade to soak in overnight. It’s not a ton of work, but does take some planning ahead.

Fry chicken in batches

Once oil is at 350°F, start frying chicken. Take care not to crowd the pan; I did only 2-3 at a time. Takes approximately 3-5 minutes per side.
Occasionally check oil temperature. Also you made need to add oil between batches as levels fall, allowing the new oil to come up to temperature before adding more chicken. Once chicken is done, set on a wire rack to cool.

Assemble sandwich and enjoy!

Slice cooled biscuits in half with a serrated knife. Spread a little dipping sauce on both inner sides to keep the sandwich from getting soggy. Layer in your cucumber kimchi slices, then carrot slaw, then a big beautiful hunk of fried chicken. Drizzle with more sauce, and then top it off with the other half of the biscuit.
