Vegan Chick-fil-A Copycat Fried Seitan Sandwich

A plant-based recreation of the iconic fast-food chicken sandwich, built on homemade seitan that mimics poultry's tender, fibrous texture. The seitan is simmered in broth, marinated in pickle juice for tangy depth, then triple-dredged and fried until the exterior shatters with crispy, seasoned crunch. Warm spice notes from paprika, cayenne, and chili powder echo the original's flavor profile, while pickle juice in both the marinade and batter add signature brightness. This sandwich suits anyone seeking restaurant-quality vegan fast food at home, perfect for lunch or casual dinners. It outpaces store-bought versions through fresh seitan made from scratch, custom spice balance, and control over oil quality and cooking temperatures—delivering genuine fried satisfaction without animal products.

Instructions

  1. 1

    Mix vital wheat gluten, pink himalayan sea salt, nutritional yeast, onion powder, and poultry seasoning in a bowl.

  2. 2

    Whisk vegetable broth and tahini until smooth in a larger bowl.

  3. 3

    Combine dry and wet ingredients and stir until well combined.

  4. 4

    Knead dough until elastic but not dry, adding gluten flour if too sticky.

  5. 5

    Divide dough into small burger-sized portions, keeping in mind they will double in size.

  6. 6

    Place portions in a casserole dish, cover completely with vegetable broth.

  7. 7

    Bake at 350 degrees F, flipping at 45 minutes, for 1 hour total. Cool.

  8. 8

    Soak cooled seitan in pickle juice and cayenne pepper for 1 hour.

  9. 9

    Combine all-purpose flour, powdered confectioners sugar, paprika, black pepper, cayenne pepper, chili powder, pink himalayan sea salt, baking powder, and garlic powder in a bowl.

  10. 10

    Whisk together pickle juice and unsweetened soy milk.

  11. 11

    Heat peanut oil to 325 degrees F in a deep fryer, frying pan, or pot.

  12. 12

    Coat seitan cutlets in dry mixture, then wet mixture, then dry mixture again.

  13. 13

    Fry cutlets until outside is crisp and golden brown, flipping occasionally, about 5-8 minutes. Drain on paper towel.

  14. 14

    Toast hamburger bun in frying pan over low heat until slightly toasted.

  15. 15

    Layer vegan cheese, fried seitan, and pickles on bun. Serve immediately.

Tips

Tip 1

Keep seitan portions smaller than intended—they expand to roughly double during simmering. Oversized portions become dense and difficult to coat evenly for frying.

Tip 2

Triple-dredging is essential: dry, wet, dry creates the signature shattered crust. Rush this step and the coating separates during frying.

Tip 3

Monitor oil temperature strictly at 325 degrees F. Hotter oil browns the exterior before seitan heats through; cooler oil yields soggy, greasy results.

Good to Know

Storage

Fried seitan keeps refrigerated in airtight container up to 4 days. Reheat in 375F oven 8-10 minutes to restore crispness. Freeze unbreaded cooled seitan up to 3 months.

Make Ahead

Prepare seitan through cooling 2 days ahead. Marinate in pickle juice up to 1 day ahead. Bread and fry same day for best texture.

Serve With

Serve immediately while seitan is hot and crust is crisp. Accompany with additional pickles, vegan mayo, or hot sauce.

Common Mistakes

Watch

Skip the rest period after kneading to avoid dense, gummy seitan that fails to fry crisp.

Watch

Omit the marinade soak to avoid bland seitan lacking the signature tangy pickle punch.

Watch

Fry above 325 degrees F to avoid burnt breading and undercooked interior.

FAQ

Can I freeze the breaded seitan before frying?

Yes. Freeze breaded cutlets on a tray uncovered for 2 hours, then transfer to freezer bags up to 3 months. Fry from frozen, extending cook time by 2-3 minutes. Thawing beforehand risks soggy coating.

What if I don't have tahini?

Substitute aquafaba (chickpea liquid) at a 1:1 ratio by volume. It provides similar binding without sesame flavor. Alternatively, use 2 tablespoons additional vegetable oil, though texture becomes slightly less tender.

How long does the finished sandwich keep?

Eat immediately for peak crispness. Refrigerate assembled sandwich up to 24 hours, but crust softens significantly. Reheat fried seitan in a 375F oven for 8 minutes to restore crunch before assembling.
