Cast-Iron Skillet Cornbread
Cast-iron skillet cornbread is a simple buttermilk batter baked in a preheated cast-iron skillet, producing crispy, golden edges with a tender, moist crumb. Ready in 35 minutes.
Someone once told me that their cast-iron skillet was the most important thing in their kitchen. I thought they were being dramatic until I watched them use it exactly once and never wash it. Just wipe it. Just wipe it. I spent years buying new pans for every recipe, nervous about scratching them, reading care instructions, and they bought one skillet once and it became better with time. Turns out that is actually how this works.
Cornbread in a cast-iron skillet is where that magic becomes obvious. The preheated pan creates a crust you cannot get any other way — crispy, caramelized, practically fried around the edges while the interior stays tender and crumbly. The batter is just buttermilk and cornmeal, nothing fussy. The pan does the work. Thirty-five minutes and you understand why people get weirdly protective of their cast iron.
Ingredients
Dry Ingredients
- 1 cup yellow cornmeal
- 1 cup all-purpose flour
- 1/4 cup granulated sugar, optional (reduce to 1 tablespoon for traditional Southern-style)
- 1 tablespoon baking powder
- 1 teaspoon kosher salt
Wet Ingredients
- 2 large eggs
- 1 cup buttermilk, room temperature
- 1/3 cup whole milk
- 1/2 cup unsalted butter, melted
- 1 tablespoon unsalted butter for the skillet
Instructions
- 1Preheat the oven to 425°F (220°C). Place a 10-inch cast-iron skillet in the oven while it preheats. This takes about 10 minutes and is crucial for developing the crispy, golden crust.
- 2In a large bowl, whisk together cornmeal, flour, sugar (if using), baking powder, and salt until evenly distributed.
- 3In a separate bowl, whisk together eggs, buttermilk, whole milk, and melted butter until well combined and smooth.
- 4Pour the wet ingredients into the dry ingredients. Stir gently until just combined. Do not overmix. A few small lumps are perfectly fine and indicate proper technique.
- 5Carefully remove the hot skillet from the oven. Add 1 tablespoon butter and swirl until completely melted and the pan is evenly coated. Immediately pour in the batter. It should begin sizzling around the edges.
- 6Bake for 20–25 minutes until the top is golden brown, a toothpick inserted into the center comes out clean, and the edges pull slightly away from the skillet with a caramelized crust.
- 7Allow the cornbread to cool for about 10 minutes in the skillet before slicing. Serve warm with butter and honey or your favorite accompaniment.
Pro Tips
- Preheating the skillet is non-negotiable. This creates the signature crispy crust that makes cast-iron cornbread special.
- Room-temperature buttermilk and milk blend more smoothly into the batter. Cold dairy can create lumps.
- Do not overmix the batter. Overmixing develops gluten, making the cornbread tough and dense instead of tender.
- For traditional Southern cornbread, reduce the sugar to 1 tablespoon or omit it entirely. Less sugar lets the cornmeal flavor shine.
- Leftover cornbread can be toasted with butter or crumbled into chili, stew, or soups.
Substitutions
Storage Instructions
Store cooled cornbread covered at room temperature for up to 2 days. It can also be wrapped tightly and refrigerated for up to 4 days. Reheat gently in a 300°F oven for 10 minutes, or toast slices for a crispy exterior.
Make Ahead
The dry and wet ingredients can be prepared separately up to 24 hours ahead. Store the dry mix in an airtight container and the wet ingredients in the refrigerator. Combine just before baking. You can also bake the cornbread ahead, cool completely, and rewarm before serving.
Frequently Asked Questions
Can I use a regular baking pan instead of cast iron?
Yes, but you will not get the same crispy crust. Cast iron retains heat exceptionally well and creates the caramelized edge. A metal or ceramic pan will work, but bake for the same time and check at 20 minutes.
What if my cornbread is too dense?
This usually means the batter was overmixed. Mix only until the dry and wet ingredients are just combined. Small lumps are fine. Overmixing develops gluten, which makes the crumb dense and tough.
Can I add cheese or jalapeños?
Absolutely. Fold in 1/2 to 1 cup shredded sharp cheddar cheese, diced jalapeños, or corn kernels into the batter just before baking. These additions add flavor without affecting the texture.
Is my skillet too small or too large?
A 10-inch skillet is ideal for this recipe. If using a smaller (8-inch) skillet, reduce baking time to 15–20 minutes. A larger (12-inch) skillet may require adding 25% more batter.
Why do you add sugar to cornbread?
Sugar is optional and regional. Northern-style cornbread uses more sugar (1/4 cup) and is sweeter. Southern-style uses 1 tablespoon or none at all and lets the cornmeal flavor dominate. Choose based on your preference.
