Since being diagnosed with celiac disease, I’ve honestly just skipped the bun when it comes to hot dogs. Most gluten-free buns fall apart the moment you take a bite — dry, crumbly, and totally underwhelming.
This gluten-free Chicago hot dog focaccia changes everything.
It’s chewy, golden, and sturdy enough to hold all the bold, classic toppings — without falling apart. From neon green relish to sport peppers and dill pickles, this is my go-to for summer gatherings and game day spreads. All the flavor of a Chicago-style dog, baked into a beautiful gluten-free focaccia.

Ingredient Notes
- Caputo Fioreglut Gluten-Free Flour – This flour is a must for this recipe and there are no substitutions. It’s made with gluten-free wheat starch, which is specially processed to remove gluten to under 20 parts per million (ppm) — meeting FDA and EU gluten-free labeling standards. It’s what gives this focaccia its airy crumb and chewy texture. Important Note: This flour is NOT safe for anyone with a wheat allergy. But for those with celiac disease, like me, it’s an absolute game-changer.
- Instant Yeast – Also called rapid-rise or quick-rise yeast. No need to proof it first — just mix it right into the dry ingredients. Most are gluten-free, but there are a few that are not (for example Red Star Platinum, Platinum Instant Sourdough and Organic Instant Yeast are NOT gluten free), so be sure to double check!
- Olive Oil – Use extra virgin olive oil for best flavor. It’s going to seem like a lot of olive oil and you aren’t wrong, but this is focaccia after all! It’s needed for flavor and to crisp up the focaccia.
- Hot Dogs – Most hot dogs are gluten-free, but always check the label to be certain. I just went with a regular length instead of a bun-length. Use all-beef hot dogs for a classic Chicago-style flavor. Score your hot dogs to help prevent them from bursting in the oven — I like to crosshatch mine for extra texture and visual appeal.
- Yellow Mustard & Relish – Chicago-style dogs call for classic yellow mustard and neon green sweet relish — the brighter the better! No ketchup, of course — we’re staying true to tradition here.
- Sport Peppers – These little pickled peppers bring the heat. If you can’t find sport peppers, you can sub in sliced pickled jalapeños or banana peppers for a similar vibe. Just be sure they’re gluten-free (many are, but always check!). I used the Vienna brand for a true Chicago-style dog.
- Pickles & Tomatoes – Use fresh, crisp dill pickle spears (cut into thinner wedges if needed) and juicy tomato slices, halved to fit the shape of each slice. They bring brightness and crunch that balance the richness of the focaccia. I prefer the pickles that you find in the refrigerated section of the grocery store. Grillo is a favorite of mine.
- Celery Salt – This finishing touch ties all the toppings together and adds that signature deli flavor. Find in the spice section at your grocery store.

Recipe FAQs
No — this recipe was specifically developed for Caputo Fioreglut. Other gluten-free flours won’t produce the same rise, chew, or structure. If you use a different flour, the dough may turn out too dense and gummy.
Yes — it contains gluten-free wheat starch that’s processed to remove gluten to below 20 parts per million, meeting both U.S. and EU gluten-free labeling standards. I have celiac and use it regularly with no issues. That said, it’s not safe for those with a wheat allergy, so always read the label.
Expert Tips
Storage instructions
Let the hot dog focaccia cool completely after baking, then slice and store in an airtight container in the refrigerator for up to 3 days. Because this recipe includes hot dogs, it should not be left at room temperature after baking.
To reheat, place on a baking sheet and warm in a 350°F (175°C) oven or air fryer for 5–8 minutes until heated through and crisp around the edges.
Only add toppings to the slices you plan to eat right away. Mustard, relish, and tomatoes don’t hold up well after chilling and reheating.
Make Ahead Tips
You can make the focaccia earlier in the day, then slice and store it plain. Right before serving, reheat and let guests build their own — it’s a fun, hands-off way to serve at parties or casual get-togethers.
You can also prep the dough up to 8 hours ahead and let it rise in the refrigerator. Once risen, leave it at room temperature for about 30 minutes and then dimple and top with poppyseeds and oil and bake as directed.
Serving suggestions
This gluten-free hot dog focaccia is a conversation starter — perfect for casual gatherings, game day, or summer cookouts.
Serve it as:
- A main dish with a side of chips, roasted red potato salad, or dill cabbage slaw
- A fun appetizer sliced into smaller squares for sharing
- A build-your-own station — set out the focaccia and toppings for a crowd-friendly, DIY moment
It pairs well with cucumber lemonade, grilled corn, or any classic cookout sides, like my watermelon cucumber salad.

Instructions
- In the bowl of a stand mixer fitted with the paddle attachment, combine 260g Caputo Fioreglut Gluten-Free Flour, 6g instant yeast, 6.25g granulated sugar, and 6g salt. Whisk to combine. Add 240g warm water and 42g olive oil. Mix on medium speed for 4 minutes until the dough is thick and sticky.
- Line a 1/8 sheet pan (6.5 x 9.5 inches) with parchment paper. Grease the pan with 14g (1 tablespoon) olive oil.
- Transfer the dough to the pan and gently spread it to the edges with oiled hands.
- Cover and let rise in a warm place for 1 to 1.5 hours, until doubled in size and puffy.
- While the dough is rising, crosshatch the hot dogs by making shallow diagonal cuts in both directions.
- Preheat the oven to 425°F (220°C) in the last 30 min of the rise. Once risen, drizzle with 14g (1 tablespoon) olive oil and use oiled fingers to dimple the surface.
- Sprinkle with 1 teaspoon poppy seeds.
- Gently press the hot dogs into the dough. Drizzle with ½ tablespoon olive oil and sprinkle with flaky sea salt.
- Bake for 23–26 minutes, or until puffed and crisp around the edges. Let cool slightly in the pan.
- Slice into 6 individual servings. Top each piece with mustard, onion, relish, tomato halves, pickle wedges, sport peppers, and a sprinkle of celery salt.
Notes
- Caputo Fioreglut Gluten-Free Flour contains gluten-free wheat starch and is tested to below 20 ppm gluten. It’s safe for most people with celiac disease, but not suitable for those with a wheat allergy.
- I always recommend baking by weight, especially with gluten-free flours. But for convenience, I’ve included volume measurements too.
- Focaccia is best the day it’s made, but leftovers can be stored in an airtight container for 2–3 days in the refrigerated and reheated in the air fryer or oven. Only top what you can eat as the toppings don’t reheat well.
