📅 Last Updated: March 20, 2026

✅ Yes! Shake Shack Has GF Buns

Shake Shack's South Lamar location offers gluten-free buns (Udi's brand, $1.50 upcharge). BUT fries are in shared fryers.

Shake Shack—the NYC-born burger chain known for premium Angus beef, crinkle-cut fries, and frozen custard—opened on South Lamar in Austin. The good news: Shake Shack offers gluten-free buns. The catch: fries are cooked in shared fryers, limiting side options for celiacs.

🍔 What's Gluten-Free at Shake Shack?

✅ Safe to Order

🍞 Gluten-Free Bun (Available!)

Shake Shack offers gluten-free buns (typically Udi's brand) for burgers and hot dogs. $1.50 upcharge.

⚠️ Note: Prepared in shared kitchen—request fresh gloves and clean prep surface.

Burgers (On GF Bun):

✅ ShackBurger (single or double) on GF bun
✅ SmokeShack (bacon, cherry peppers) on GF bun
✅ Shroom Burger (fried portobello—verify GF bun available)
✅ Lettuce wrap option (skip bun entirely)

Hot Dogs (On GF Bun):

✅ Hot dogs with GF bun or lettuce wrap

Shakes & Frozen Custard:

✅ Classic shakes (vanilla, chocolate, strawberry, black & white)
✅ Plain frozen custard in cup (NO cones, no cookie mix-ins)

❌ NOT Gluten-Free

⚠️ Fries Are Unsafe for Celiacs

Shake Shack fries are cooked in SHARED FRYERS with breaded items. Cross-contamination makes them unsafe for celiac disease.

This is a major limitation—you get a GF bun but can't have fries. Your only side options are limited.

❌ Crinkle-cut fries (shared fryer)
❌ Breaded chicken sandwich
❌ Regular buns
❌ Cones (contain gluten)
❌ Concretes with cookie mix-ins

📍 Shake Shack Austin Location

South Lamar: 1100 S Lamar Blvd, Suite 2100, Austin, TX

💡 Parking: Free 3-hour parking available

💡 GF Experience: Staff are generally trained on GF orders. Communicate clearly about celiac and request fresh gloves.

💡 Final Verdict

✅ Shake Shack is Decent for GF (With Limitations)

For celiac disease: ⚠️ Mixed. You get a GF bun (good!), but no safe fries (bad). Order burger + shake and accept the limited sides.

Our take: Shake Shack tries harder than most chains by offering GF buns. The quality is good, but the shared fryer for fries is a major limitation. Worth trying on South Lamar if you want premium burgers with GF buns.
