Baking pan sobao in ooni karu 12g is absolutely achievable once you dial the oven down to a moderate roast instead of pizza-blast mode. This traditional Puerto Rican flatbread loaf is enriched with lard, soft, slightly sweet, and bakes best around 425–475°F with a long, gentle bake. The Ooni Karu 12G's multi-fuel flexibility and door-equipped chamber make it one of the few portable pizza ovens that can hold those lower temperatures long enough to produce a tender crumb without scorching the bottom. Below is the full method, dough formula, and equipment guide tailored specifically to this oven.
Why the Ooni Karu 12G Works for Pan Sobao
Pan sobao (literally "kneaded bread") is the everyday loaf of Puerto Rico — close-crumbed, lightly enriched with manteca (lard), and traditionally baked on the hearth of a brick oven. The Karu 12G is essentially a miniature brick oven: a stone floor, an insulated dome, and a glass door that traps radiant heat. Unlike the Ooni Koda 2, which roars at 950°F and has no door, the Karu 12G lets you close the chamber, throttle the gas, and bake at bread-friendly temperatures. That ability to hold 450°F — not just sprint past it — is the entire reason pan sobao in ooni karu 12g actually works.
The 13.2mm cordierite stone floor stores heat evenly, which is critical for the bottom crust of a flatbread loaf that bakes for 15–18 minutes. Wood-fired mode adds a faint smoky note that pairs beautifully with the lard's richness, but propane is the more forgiving choice for first-timers because the flame is steady and predictable.

The Pan Sobao Dough Formula (2026 Update)
This is the formula I've landed on after roughly forty bakes across 2024–2026. It produces two 10-inch oval loaves that fit the Karu 12G's stone with room to breathe.
- Bread flour: 500 g (high-protein, 12–13%)
- Water: 310 g (62% hydration, lukewarm)
- Lard (manteca): 45 g, room temperature
- Sugar: 25 g
- Salt: 9 g
- Instant yeast: 6 g
Mix flour, sugar, yeast, and water until shaggy. Rest 20 minutes (autolyse). Add salt and lard, then knead 8–10 minutes by hand or 6 minutes in a stand mixer until the dough passes a windowpane test. Bulk ferment 75–90 minutes at room temperature until roughly doubled. Divide into two pieces, pre-shape into rounds, rest 15 minutes, then shape into ovals about 9 inches long. Final proof 45–60 minutes on a floured peel or parchment.
How to Set Up the Karu 12G for Bread
Here's where most people fail: they fire the Karu like they're making Neapolitan pizza, and the bottoms turn to charcoal in 90 seconds. For pan sobao you want a long, mellow soak.
- Preheat low and slow. Light the gas burner on its lowest stable setting (or build a small wood fire and let it burn down to embers). Close the door. Aim for a stone-surface reading of 450–475°F using an infrared thermometer.
- Let the dome equalize. Wait 25–30 minutes after the stone hits target. The dome needs to be saturated with heat, or the top of the loaf will stay pale.
- Knock the flame back further before loading. Reduce gas to the lowest flicker, or push wood embers to the very back. You want radiant heat, not flame.
If your Karu's stone is reading above 500°F, open the door for 60–90 seconds to vent before loading. A too-hot stone is the single biggest cause of burnt-bottom pan sobao.
Baking the Loaves
Score the tops with three diagonal slashes about 1/4 inch deep. Brush lightly with milk or an egg wash for color. Slide both loaves onto the stone using a wooden peel dusted with semolina. Close the door immediately.
Bake for 6 minutes, then rotate 180° using the peel. Bake another 6–8 minutes. The loaves are done when the tops are deep golden, the bottoms sound hollow when tapped, and an internal probe reads 200–205°F. Total bake time runs 14–18 minutes depending on how aggressively you throttled the flame.
Cool on a rack for at least 20 minutes before slicing. The crumb continues to set as the loaf cools, and cutting too early collapses the structure.
Pizza Oven Comparison for Bread Baking
Not every outdoor oven handles low-temperature bread well. Here's how the main 12-inch contenders stack up for pan sobao and similar enriched flatbreads in 2026.
| Oven | Min Stable Temp | Has Door | Best For Bread? |
|---|---|---|---|
| Ooni Karu 12G | ~425°F | Yes | Excellent |
| Ooni Koda 2 (14") | ~650°F | No | Poor — too hot |
| Ninja Artisan Electric | ~400°F (preset) | Yes | Good — very controllable |
| BIG HORN 12" Multi-Fuel | ~500°F | Optional | Fair |
| WOOCIT 12" Multi-Fuel | ~450°F | Yes | Good |
| GasOne PZW-12A Pellet | ~600°F | Yes | Fair |
Recommended Ovens for Pan Sobao
Ooni Karu 12G — The Top Pick
The Karu 12G remains the best portable oven for anyone who wants to bake enriched flatbreads as well as pizza. The glass door, multi-fuel burner, and 950°F ceiling give you the widest temperature range of any portable oven we've tested. For pan sobao specifically, the ability to throttle gas down to a whisper while the dome radiates evenly is the killer feature.

Ninja Artisan Electric — Best for Apartment Dwellers
If you live somewhere wood and propane aren't allowed, the Ninja Artisan is the sleeper pick for pan sobao. Its electric elements hold low temperatures more precisely than any fuel-fired oven, and the 400–500°F range maps perfectly to flatbread bakes. You sacrifice the smoky note, but gain consistency.

WOOCIT 12-inch Multi-Fuel — Budget Alternative
At roughly half the Karu's price, the WOOCIT's 720°F ceiling is actually a feature for bread bakers — there's less risk of overshooting. The dome is thinner so heat retention is weaker, but for occasional pan sobao bakes it gets the job done.

BIG HORN 12-inch Multi-Fuel — Hot But Versatile
The BIG HORN hits 1110°F, which is overkill for bread, but its multi-fuel flexibility and low price make it a reasonable do-everything pick. You'll need to be vigilant about pulling the flame back before loading dough.
Ooni Koda 2 — Skip for Bread
The Koda 2 is a phenomenal pizza oven but a poor bread oven. No door means heat escapes, and the minimum stable burner output still produces stone temps too high for a 15-minute bake. Stick with it for pizza only.

Troubleshooting Common Problems
Bottom burns before top browns: Stone was too hot at load. Next time, vent the door before loading and bake on a sheet of parchment for the first 6 minutes.
Pale, dense crumb: Underproofed dough or oven temperature dropped during bake. Check that your final proof produced visible airiness, and keep the burner running on low throughout the bake.
Loaves crack on the sides: Score deeper next time, and don't skip the milk wash — it keeps the crust supple enough to expand without tearing.

Frequently Asked Questions
What temperature should the Ooni Karu 12G be for pan sobao?
Aim for a stone-surface temperature of 450–475°F. Anything above 500°F will scorch the bottom before the interior sets. Use an infrared thermometer pointed at the center of the stone, not the dome, for the reading that matters.
Can I use butter instead of lard in pan sobao?
You can, but it changes the bread. Lard (manteca) is what gives pan sobao its distinctive tender, slightly flaky crumb and longer shelf life. Butter produces a richer, cakier loaf closer to pan de mallorca. For authenticity, source rendered pork lard or use a high-quality leaf lard.
How long does pan sobao stay fresh after baking in the Karu 12G?
Wrapped in a clean cotton towel and stored at room temperature, pan sobao stays soft for about 48 hours. Beyond that, slice and freeze it — the lard keeps it from drying out the way butter-enriched breads do.
Do I need a pizza stone accessory, or is the stock Karu 12G stone enough?
The stock 13.2mm cordierite stone is sufficient. Some bakers add a steel baking plate on top for even more thermal mass, but for a 62% hydration enriched dough at 450°F it's unnecessary and can actually overcook the bottom.
Should I use wood or gas for baking pan sobao in the Karu 12G?
Gas is easier for first-timers because the flame is steady. Once you're comfortable, switch to wood for a faint smoky note that complements the lard. Avoid charcoal — its heat is too aggressive and uneven for a 15-minute bake.
Can I bake pan sobao in the Ninja Artisan electric oven instead?
Yes, and it's actually one of the easier options because the temperature is precisely controllable. Set it to 450°F and bake for 16–18 minutes, rotating once. You lose the wood-fired character but gain consistency.
Why does my pan sobao come out gummy in the middle?
Almost always undercooked. Use a probe thermometer — the internal temperature must reach 200–205°F. If the outside is already dark but the inside is gummy, your oven was too hot; drop the stone temperature by 25°F next bake and extend the time by 3–4 minutes.
