Southern Recipes Cookbook: Cast-Iron Buttermilk Cornbread

Cast-iron buttermilk cornbread is a Southern American quick bread made with cornmeal, flour, buttermilk, and eggs, baked in a hot skillet until its edges turn crisp. This version keeps the crumb tender and lightly tangy, with a little butter for flavor; Southern and family recipes vary, including whether they use sugar, white or yellow cornmeal, or a skillet.

Ingredients

2 cups (300 g) yellow cornmeal, preferably medium grind
1 cup (125 g) all-purpose flour
1 tablespoon (12 g) baking powder
1/2 teaspoon (2 g) baking soda
1 teaspoon (6 g) fine salt
1 3/4 cups (420 ml) buttermilk, shaken
2 large eggs (about 100 g without shells), at room temperature if possible
4 tablespoons (56 g) unsalted butter, melted and slightly cooled
1 tablespoon (15 ml) neutral oil, such as canola or grapeseed, for the batter
1 tablespoon (15 ml) neutral oil, for the skillet

Instructions

Heat the oven and skillet. Set a rack in the center of the oven and heat to 425°F (220°C). Put a 10-inch (25 cm) cast-iron skillet in the oven as it heats. Allow about 15 minutes for the oven to reach temperature; keep the skillet inside so it gets thoroughly hot. If you do not have cast iron, use a heavy oven-safe 9-inch (23 cm) round pan, though the crust may be a little less crisp.
Mix the dry ingredients. While the oven heats, whisk the cornmeal, flour, baking powder, baking soda, and salt in a large bowl. Break up any lumps of baking soda or baking powder so the rise is even. In a second bowl, whisk the buttermilk and eggs until combined, then whisk in the melted butter and the 1 tablespoon of oil. The butter should be warm and fluid, not piping hot, so it does not scramble the eggs.
Combine without overmixing. Pour the buttermilk mixture into the dry ingredients. Stir with a spatula just until no broad patches of dry flour remain. A few small lumps are fine. The batter should be thick but pourable; do not beat it smooth, since vigorous mixing can make the baked crumb firm. Let the batter stand for 2 minutes while you prepare the pan, not long enough for the leavening to lose its lift.
Oil the hot skillet and add the batter. Carefully remove the skillet with oven mitts; the handle will be extremely hot. Swirl 1 tablespoon of oil around the bottom and a little way up the sides. Pour in the batter. It should sizzle at the edges. Work carefully to avoid splashes, then return the skillet to the center rack right away.
Bake until set. Bake for 20 to 24 minutes, checking at 20 minutes. The top should be golden, the center should spring back lightly when touched, and a toothpick inserted in the middle should come out clean or with a few moist crumbs. For a thermometer check, the center should register about 195–200°F (90–93°C); this is above the USDA FSIS safe minimum of 160°F (71°C) for an egg dish. If the top browns before the center is done, loosely cover it with foil and continue baking a few minutes.
Rest and serve. Set the skillet on a heatproof surface and let the cornbread rest for 10 minutes so it can finish setting and slice more cleanly. Run a thin spatula around the edge, cut into 8 wedges, and serve warm. Use a dry oven mitt or a handle cover when moving the skillet, and remember that cast iron stays hot well after it leaves the oven.

Tips

Choose cornmeal you like to eat. Medium-grind yellow cornmeal gives this loaf a noticeable but not gritty texture. Fine cornmeal makes a closer, softer crumb; coarse meal gives a more pronounced crunch and may feel drier. White cornmeal works in the same quantity and makes a milder-looking loaf.
Make a buttermilk substitute only if needed. For this quantity, stir 1 tablespoon (15 ml) lemon juice or white vinegar into enough milk to make 1 3/4 cups (420 ml), then let it stand for 5 minutes. It provides acidity for the baking soda, but the result is usually less thick and tangy than real buttermilk. Plain yogurt thinned with a little milk is another workable option.
Keep the skillet hot, but handle it deliberately. A well-heated pan helps form the browned edge. Put a folded towel or a conspicuous heatproof cover over the handle as soon as the skillet comes out; the handle may look cool even while it is hot enough to burn.
Measure flour lightly and stop mixing early. Spoon flour into its measuring cup and level it rather than packing it down. Too much flour or excessive stirring can make cornbread dense. If the batter seems especially stiff, check that you measured the buttermilk accurately before adding extra liquid.

Serving Suggestions

Serve wedges warm with butter, or set them beside a bowl of chili, vegetable soup, or slow-simmered beans. The crisp edge and tender center also work well alongside Southern-style greens, stewed tomatoes, or a plate of roasted vegetables. For a simple supper, pair a wedge with soup and a green salad; for a larger meal, cornbread can take the place of rolls or biscuits.

For a savory plate, offer softened butter with a pinch of salt, or drizzle a little honey over an individual serving if you enjoy a sweet-and-savory contrast. Crumble leftover cornbread into a bowl of beans just before eating so it softens without disappearing into the broth. If serving it with a saucy dish, cut the loaf into wedges at the table rather than crumbling the whole skillet in advance.

Variations

Less tangy and more tender: Replace up to 1/2 cup (75 g) of the cornmeal with an additional 1/2 cup (63 g) of flour. This shifts the balance toward a softer, more cake-like crumb and makes the corn flavor less pronounced. Keep the remaining quantities and baking time, but begin checking at 20 minutes.

A touch of sweetness: Whisk in 1 to 2 tablespoons (12–25 g) of sugar with the dry ingredients. Sugar is welcome in some Southern and household versions, while others leave it out; it is a preference rather than a requirement for this recipe. It will make the crust brown a little more readily, so check the top near the start of the doneness window.

Cheese and scallions: Fold in 1 cup (about 100 g) of grated sharp cheddar and 2 thinly sliced scallions after combining the wet and dry ingredients. The additions make the loaf richer and more savory. Avoid adding a large amount of wet vegetables, which can weigh down the batter and leave the center damp.

Use a baking dish instead: If you do not own an oven-safe skillet, grease a 9-inch (23 cm) round cake pan or an 8-inch (20 cm) square metal pan. Heat the oven as directed, but do not preheat an empty glass dish; add the batter to the greased dish at room temperature. The edges may not develop quite the same skillet crust, and the bake may take a few minutes longer, so check the center rather than relying only on the clock.

Storage and Reheating

Let leftovers cool until they are no longer steaming, then transfer them to a covered container. Refrigerate within 2 hours of baking; stored at 40°F (4°C) or colder, the cornbread keeps for 3 to 4 days. For the best texture, keep pieces whole until serving, since cut surfaces dry out more quickly. Do not leave it at room temperature overnight.

To reheat a piece, cover it loosely with foil and warm it in a 300°F (150°C) oven for about 8 to 12 minutes, or microwave it in short bursts until warm. A toaster oven can restore some crispness to the edge. Reheat only the portions you plan to eat, and if reheating leftovers as a hot dish, bring them to 165°F (74°C), the USDA FSIS safe temperature for reheated leftovers.

For longer storage, wrap fully cooled wedges individually and freeze them in a freezer-safe bag for up to 2 months for best quality. Thaw in the refrigerator or reheat from frozen, allowing extra time and checking that the center is hot. Freezing can soften the crust, but a few minutes in a hot oven after thawing helps refresh the exterior.

Frequently Asked Questions

Can I make this cornbread without a cast-iron skillet?
Yes. Use a greased, oven-safe 9-inch (23 cm) metal cake pan or an 8-inch (20 cm) square metal pan. The bake may take a few minutes longer, and the edges will likely be less crisp because the pan is not preheated with oil in the same way. Avoid putting an empty glass dish into a hot oven, since rapid temperature changes can damage glass.

Why did my cornbread turn out dry or crumbly?
Common causes are too much cornmeal or flour, overbaking, or measuring a thick batter inaccurately. Weighing the dry ingredients helps; if using cups, spoon flour into the cup rather than scooping and packing it. Start checking at 20 minutes, and take the cornbread out once the center is set and the thermometer reads in the stated range.

Can I prepare the batter ahead?
It is better to mix and bake it promptly. Once buttermilk meets the baking soda and baking powder, the leavening begins working, so a long wait can reduce the rise. You can measure the dry ingredients and refrigerate the wet ingredients separately ahead of time, then combine them shortly before pouring the batter into the hot skillet.

Can I use self-rising cornmeal mix?
This recipe is written for plain cornmeal, so self-rising mix may already contain flour, salt, and leavening. Those blends vary, making a direct cup-for-cup swap unpredictable. For the most reliable result, use plain cornmeal; if using a self-rising blend, follow its package guidance and adjust the flour, salt, and baking powder rather than adding all the listed leaveners automatically.

Is Southern cornbread supposed to contain sugar?
There is no single rule that covers every Southern cook or region. Some versions are savory and have no added sugar, while others include a little or are noticeably sweet. This recipe is mildly savory as written, and the small optional addition in the variations section lets you adjust it without changing the method.
