To bake authentic sfincione in Gozney Arc XL evenly, preheat the oven to a moderate 575-625°F (not full blast), use a heavy oiled steel or anodized aluminum pan sized to fit the stone, and run the burner at roughly 35-45% output with the door cracked for the first 6 minutes. The Arc XL's wide stone, rolling flame, and rear heat curtain are actually ideal for thick Sicilian-style square pizza once you stop treating it like a 90-second Neapolitan oven. Rotate the pan 180° at the halfway mark, finish uncovered for color, and you'll pull a 1-inch tall, honeycombed, golden-bottomed sfincione that tastes like Palermo.
This guide walks through dough hydration, pan choice, flame management, and the exact temperature curve that solves the two complaints we hear most: scorched tops with gummy centers, or pale crusts that never crisp. We'll also compare the Arc XL approach to a few other outdoor pizza ovens in case you're still shopping or want a backup for tailgates.
Why Sfincione Fights the Arc XL (And How to Win)
Sfincione ("little sponge") is not a Neapolitan pie. It's a high-hydration, focaccia-adjacent Sicilian square baked in oil with caciocavallo, anchovies, breadcrumbs, oregano, and slow-cooked onions. The dough sits between 75-82% hydration and the bake wants 550-625°F for 15-22 minutes, not 900°F for 60 seconds. The Arc XL is engineered to scream up to 950°F+ with a sweeping rear flame, so the obvious risk when baking sfincione in gozney arc xl is incinerating the cheese before the crumb sets.
The good news: the Arc XL has more thermal mass and a longer hearth than the Karu or Koda lines, which means once you settle it at a lower setpoint, it holds beautifully steady. The rolling rear flame becomes an asset rather than a liability when you angle the pan correctly and use the door as a damper. See our companion piece on low-temperature baking in the Arc XL for the underlying thermodynamics.
Equipment Checklist Before You Start
- Gozney Arc XL (gas or with the optional dual-fuel kit)
- 12x14 in or 10x14 in heavy-gauge anodized aluminum or blue-steel pan (3/4 in to 1 in deep)
- Infrared thermometer (non-negotiable for stone reads)
- Long offset spatula or pizza peel sized to lift the pan
- Heat-resistant gloves rated 500°F+
- Aluminum foil tent (for the first half of the bake)
The Dough: 24-48 Hour Cold Ferment
Sfincione needs an open crumb that traps oil and tomato. Use this formula for one 10x14 in pan:
- 500 g 00 or bread flour (12-13% protein)
- 400 g water (80% hydration)
- 10 g sea salt
- 2 g instant dry yeast
- 15 g extra-virgin olive oil
Mix, autolyse 30 minutes, fold every 30 minutes for 2 hours, then cold ferment 24-48 hours. Two hours before bake, oil the pan with 30 g EVOO, press the dough out, cover, and let it rise at room temp until it has visible bubbles across the surface and jiggles like a waterbed.
The Bake: Step-By-Step Temperature Curve
Stage 1 - Preheat (20-25 minutes)
Light the Arc XL on the middle setting. Target a stone temperature of 575-600°F measured with an IR gun. If it climbs past 650°F, dial back and crack the door for 60 seconds. Stable mid-range heat is the entire ballgame for sfincione in gozney arc xl.
Stage 2 - Load and Tent (0-6 minutes)
Slide the pan in with the long edge perpendicular to the flame. Loosely tent with foil for the first 6 minutes - this prevents the rear flame from blistering the top before the crumb expands. Burner at roughly 40% output.
Stage 3 - Rotate (6-12 minutes)
Remove the foil. Rotate the pan 180°. The bottom should already show the first signs of golden lift if you peek with the offset spatula. Keep the flame steady; do not crank it.
Stage 4 - Color and Crisp (12-20 minutes)
Bump the burner to 60% for the final 4-6 minutes to caramelize the cheese, toast the breadcrumb topping, and crisp the underside in the oil bath. Pull when the top is mahogany-flecked and the internal crumb reads 205-210°F.
Stage 5 - Rest (5 minutes)
Slide onto a wire rack. Resting lets steam escape so the bottom stays crackly. Cut into 9 squares.
Common Failure Modes and Fixes
| Problem | Cause | Fix |
|---|---|---|
| Burnt back edge, raw front | Stone too hot, no rotation | Drop to 575°F, rotate at 6 min |
| Pale, soft bottom | Not enough oil; cold pan | Use 30 g EVOO; preheat the empty pan 2 min |
| Gummy crumb center | Pulled too early | Target 208°F internal |
| Cheese scorched in 4 min | Foil omitted, flame too high | Tent first 6 minutes |
| Dough won't rise in pan | Cold proof, oil too thick | 2-hour warm proof; thinner oil layer |
Recommended Outdoor Pizza Ovens (If You Want a Companion or Alternative)
The Arc XL is our baseline assumption, but plenty of readers ask what else can pull off a square Sicilian. Here are picks that genuinely handle the moderate, sustained heat sfincione needs. Skip anything that only runs full-blast - it'll torch the topping.
Best Gas Companion: Ooni Koda 2
If you already love the Arc XL but want a smaller, faster propane unit for weeknight rounds, the Koda 2's 14-inch hearth and improved low-end flame control make it surprisingly capable for thicker pies in a small steel pan. It doesn't have the Arc's mass, but the burner modulates low enough for a passable 600°F bake. View the Ooni Koda 2 on Amazon.
Best Multi-Fuel Backup: Ooni Karu 12
For campouts where the Arc XL isn't portable enough, the Karu 12 runs on wood, charcoal, or gas with the optional burner. Hits 950°F for Neapolitan but can also hold a steadier 600°F if you load smaller fuel and let the firebox coast. Great for sfincione-in-a-small-pan when traveling. View the Ooni Karu 12 on Amazon.
Best Budget Multi-Fuel: BIG HORN 12-inch
If you want a second oven dedicated to lower-temp bakes (sfincione, focaccia, even pan cookies) without spending Arc money, the BIG HORN handles wood, gas, and electric and tops out at 1110°F - so it has plenty of headroom but also runs reasonably gentle at mid output. View the BIG HORN on Amazon.
Best Indoor-Style Alternative: Ninja Artisan Electric
Sfincione, frankly, also bakes brilliantly in the Ninja Artisan because electric coils give dial-precise temperature control between 400°F and 700°F. If your Arc XL is tied up doing 60-second Margheritas for guests, the Artisan can do the slow Sicilian in parallel. View the Ninja Artisan on Amazon.
Best Pellet Option: GasOne PZW-12A
Pellet ovens give a wood note without the babysitting and tend to hold mid-range temperatures with less drift than wood-only models, which is exactly what sfincione wants. Compact, affordable, and surprisingly stable at 600°F. View the GasOne PZW-12A on Amazon.
Topping Strategy for Authentic Sicilian Flavor
The classic Palermo sfincione layers, top to bottom: toasted breadcrumbs with oregano, grated caciocavallo (or pecorino), slow-cooked onion confit, crushed San Marzano with anchovy, and the high-hydration dough underneath. Apply toppings in that reverse order on the dough. The breadcrumb layer is non-negotiable - it absorbs surface oil and prevents the sog that ruins lesser Sicilians. For a deeper dive on the regional sauce, see our authentic sfincione sauce recipe.
Pan Choice Matters More Than You Think
A 1/4 in steel pan transfers heat too aggressively under Arc XL flame and scorches the bottom in 8 minutes. A thin aluminum sheet warps and gives uneven browning. The sweet spot is a 1/8 to 3/16 in anodized aluminum or blue steel pan with rolled edges. Detroit-style pans technically work but their tall walls trap steam and slow the crust set. If you can only own one pan for this, get a 10x14 in anodized aluminum at 3/4 in deep.
Frequently Asked Questions
What stone temperature is best for Sicilian square pizza in the Gozney Arc XL?
Target 575-600°F measured with an infrared thermometer at the spot where the pan will sit. Above 650°F you'll scorch the bottom before the crumb sets; below 525°F you won't get the leopard-spotting on the cheese. The Arc XL's stone holds this range well if you let it settle for a full 20 minutes after the initial preheat.
Can I bake sfincione in the Gozney Arc XL without a foil tent?
You can, but only if you keep the burner below 30% output and accept a paler top. The foil tent for the first 6 minutes is the easiest way to even out heat distribution because the Arc XL's rolling rear flame hits the top of any tall pan first. Tent on, bake, remove, rotate - it's the simplest fix to the most common complaint.
How long does sfincione take in the Arc XL versus a regular home oven?
15-20 minutes in the Arc XL at 575-600°F versus 25-30 minutes in a home oven at 475°F. The Arc finishes faster because the stone radiates more aggressively from below and the rear flame caramelizes the top quickly once you remove the foil tent. Internal temp is the real doneness signal - shoot for 205-210°F.
What flour is best for high-hydration Sicilian dough in an outdoor pizza oven?
Use a strong bread flour or Italian 00 with 12.5-13% protein. Caputo Pizzeria or King Arthur Bread Flour both work. Lower-protein 00 (like Caputo Chef) won't hold the 80% hydration window and will tear during the pan stretch. If you want extra structure, blend 80% bread flour with 20% semola rimacinata for a more Sicilian character.
Do I need a Gozney Arc XL or will a Koda 2 work for sfincione?
The Koda 2 will work for a smaller 9x12 in sfincione if you keep the burner low and use a heavy pan. It just doesn't have the same hearth depth, so the back edge runs hotter and demands more rotation. The Arc XL is simply more forgiving. If you're shopping new specifically for Sicilian bakes, the Arc XL is the better tool; if you already own a Koda 2, you can absolutely make it work.
Can I bake focaccia in the Gozney Arc XL using this same method?
Yes - focaccia and sfincione share a near-identical dough and bake profile. Drop the stone target to 525-550°F (focaccia wants slightly less aggressive browning), skip the tomato and breadcrumb topping, and finish with rosemary, flaky salt, and a heavy EVOO drizzle. The pan, hydration, and rotation strategy are otherwise identical.
Why does my Sicilian crust come out gummy in the center even when the top looks done?
Almost always undertemperature or underbake time, not overtopping. High-hydration doughs need internal temps of 205-210°F to fully gelatinize the starches. If the top is dark before the inside is done, your stone is too hot - drop to 575°F and bake longer rather than running hotter and shorter. A digital probe in the center of the slab settles the debate.
Final Notes
The Arc XL was marketed for Neapolitan but it's quietly one of the best outdoor pizza ovens for the slower Italian regional styles - sfincione, focaccia barese, sfincione bagherese, even a respectable Roman al taglio if you have a longer pan. The trick is unlearning the "max temp = good" instinct that high-end pizza oven marketing drills into you. Bake low, bake patient, rotate once, and you'll out-perform most pizzerias outside of Palermo. For more lower-and-slower techniques, browse our Arc XL recipe index.
