You can bake bread on a grill? Yes! It’s super easy.
The beauty of quick breads is that you don’t need any yeast. With this Irish soda bread recipe, you don’t even need an oven. With steady indirect heat and the lid down, your gas or charcoal grill functions like an outdoor oven. Luckily, Irish soda bread is one of the simplest breads ever devised. Not only is there no yeast, there’s no proofing time, and no kneading. This bread relies entirely on baking soda reacting with acidic buttermilk for lift, which makes it particularly well suited for baking on a grill. If your oven is full or you prefer to cook outdoors, this method delivers a tender crumb and crisp golden crust. The key is a stable temperature of 375°F using a two-zone grill setup.
The science of Irish soda bread
This bread depends on flour for structure, buttermilk for acidity, and baking soda for leavening. When buttermilk meets baking soda, lactic acid in the buttermilk interacts with the baking soda, producing carbon dioxide gas. This gas gets trapped in the dough or batter, causing it to rise and creating a light, tender texture. Click here to learn more about the science of baking soda. The leavening reaction begins immediately, so the dough should be baked soon after mixing. Like other quick breads, Irish soda bread does not benefit from resting. It’s also essential to mix the dough quickly and briefly without overhandling, as overmixing develops excess gluten and creates a tough, dense loaf instead of a tender one. It’s the same principle used when mixing up pancakes, another type of quick bread. The dough or batter should look slightly shaggy when fully mixed.
Traditional Irish soda bread has an “X” cut into the top, not as decoration, but because it allows heat to penetrate faster, which helps the dough expand into a higher, lighter loaf. When the bread is done, it should be lightly browned on top and register 200 to 205°F on an instant-read thermometer. At that temperature, the interior structure has set and the loaf will slice cleanly without being gummy.
Irish Soda Bread FAQs
Yes. Mix one tablespoon lemon juice or distilled white vinegar into 1 3/4 cups whole milk and let it sit for five minutes before using. The acids in lemon juice or vinegar are what activate the baking soda.
If you need to prep ahead, measure the dry ingredients and wet ingredients separately and combine them just before baking. You can also bake the bread completely early in the day then rewarm it gently on the grill at 300°F for 8 to 10 minutes before serving. But to get the best rise and a light texture in the bread, you want to get the mixed dough onto the grill within about 10 to 15 minutes of combining the wet and dry ingredients. The leavening reaction between buttermilk and baking soda happens immediately after they are mixed together.
No. A gas or charcoal grill with a 2-zone set up at 375°F functions like an outdoor oven. As long as the loaf is positioned away from direct flame and the temperature remains steady, the results are comparable to oven baking inside.
Use a two-zone fire and position the skillet over the cooler side of the grill. A heavy cast iron pan protects the bottom crust and promotes even baking.
No. This bread benefits from clean, neutral heat. Smoke can overpower the mild flavor of the bread and is not recommended for this recipe.
It should look golden brown on the surface, and it should reach 200 to 205°F on an instant-read thermometer. At this point the crumb is fully set, and the loaf will slice cleanly without being gummy.
