Chik Fil A Chicken Sandwich Recipe (vegetarian dupe)
This Chick-fil-A chicken sandwich dupe is completely meatless but unbelievably crispy, juicy, and flavorful—thanks to oyster mushrooms, a thick buttermilk batter, and a spiced flour coating that mimics fried chicken perfectly.
Pick your Mushrooms: choose large oyster mushrooms that can be shaped into sandwich-sized clusters.
Make the Wet Batter: Whisk together the buttermilk, hot sauce, pickle juice, powdered sugar, salt, garlic powder, onion powder, and flour.
Mix the Dry Batter: In a separate bowl, combine all-purpose flour, salt, garlic powder, onion powder, chili powders, smoked paprika, and powdered sugar.
Batter the Mushrooms: Dip mushrooms into the wet batter, coating completely. Shake off the excess. Transfer to the dry mix and firmly press the flour onto each piece, clumping it to create texture. It will start to get a bit sticky—keep layering and pressing until the outer coating is completely dry.
Fry Until Crispy: Heat oil to 350°F and fry the battered mushrooms until golden brown and crispy—about 3–5 minutes per side. Don't overcrowd the pan.
Toast and Assemble: Toast brioche buns. Add mayo, lettuce, tomato, pickles, a slice of pepper jack cheese, and your crispy mushroom fillet.
