Polenta Cornbread

Polenta cornbread is that skillet side you'll reach for on chili night, BBQ Friday, or when you just want something golden to swipe through jalapeno honey butter. If you've wondered whether polenta really makes a difference, this is the cornbread that proves it: crisp edges, tender middle, and a sturdy crumb that holds up to dunking.

As a Southern dietitian, you can trust I know my way around cornbread. I grew up with my dad making a batch almost every week, usually alongside brunswick stew or a simple pot of beans, so that crisp edge and tender center is baked into my DNA. 

This version uses polenta for a little extra texture and a golden bite. I've been experimenting with it recently and pulled together simple, clear tips so you can get that same skillet magic without the guesswork!

Serve it with my dutch oven chili or set it beside weeknight mains like BBQ sheet pan chicken or easy chicken meatballs, apple pulled pork for a cozy, mix-and-match dinner spread.

Why You'll Love This Recipe

• Crispy edges without extra work: Preheat a greased cast-iron skillet so the batter hits a hot surface and the crust forms for you.
• Balanced, not too sweet: A small scoop of sugar lifts the corn flavor while buttermilk keeps the crumb tender and moist.
• Busy-night friendly: Pantry staples and a quick bake time make this an easy side that pairs well with weeknight mains!

Serve this up with other Southern sides like twice baked mashed potatoes, cranberry bourbon sauce, or hot honey brussel sprouts.

Ingredients

Here's exactly what you need for crisp edges, a tender crumb, and pantry-friendly prep.

• All-purpose flour: This gives the batter enough structure so slices hold together for dunking and don't crumble when you cut them.
• Dry yellow polenta: I use a medium-grind dried polenta (not the cooked, ready-to-eat variety), which gives the classic texture and crisp, golden edges that make this cornbread special!
• Eggs: These help the crumb set cleanly for tidy slices and add a bit of richness without making it heavy. 
• Buttermilk: This adds tenderness and gentle tang, and it also helps the cornbread brown nicely. If you don't have buttermilk, stir 1 tablespoon lemon juice or vinegar into 1 cup milk, let it sit for 5 minutes, and use it as a swap.
• Sugar: This small amount boosts the corn flavor without turning the cornbread into cake. You can adjust it to taste, if needed.

Substitutions & Variations

Customize with easy flavor add-ins so this cornbread recipe with polenta fits your kitchen and taste.

• If you need a gluten-free option, swap in a 1:1 gluten free flour and rest the batter for 10 minutes so the starches hydrate.
• If you prefer sweeter or more savory cornbread, adjust the sugar up or down and season the batter to taste.
• If you like a herby vibe, fold in 1 teaspoon chopped fresh rosemary and ½ teaspoon cracked black pepper.
• Kick up the heat by folding in 1-2 finely chopped jalapeños and 1 cup shredded sharp cheddar, then finish with a drizzle of jalapeño honey.
• Brush the hot cornbread with warm honey butter or maple butter for a sweet finish
• If you need individual portions, bake the batter in a greased 12-cup muffin tin at 400°F for 12-15 minutes.

How To Make Polenta Cornbread Recipe

 Follow this step-by-step method for a smooth batter, hot skillet, and golden bake.

Step 1: Preheat oven to 425°F and place a 10-inch cast iron skillet inside to heat while you make the batter.

Step 2: In a large bowl, whisk together the flour, polenta, baking powder, baking soda, salt, and sugar until evenly combined.

Step 3: In a medium bowl, whisk the eggs, buttermilk, 3 tablespoons melted butter, and the oil until smooth.

Step 4: Pour the wet ingredients into the dry and stir just until no dry flour remains, careful to not overmix the batter.

Step 5: Using oven mitts, carefully remove the hot skillet and add 1 tablespoon butter, tilting or brushing the pan so the bottom and sides are fully coated.

Step 6: Pour the batter into the hot, buttered skillet and bake for 20-25 minutes until the top is golden and a toothpick inserted comes out clean.

Step 7: Let the cornbread rest for 10 minutes, then slice and serve warm with butter, honey, or your favorite savory mains.

Storage

Keep leftovers fresh so the texture stays extra delicious!

• Leftover: Let the cornbread cool completely, then wrap well and keep at room temperature for up to 2 days or refrigerate for up to 4 days to keep the crumb moist.
• Freezer: For longer storage, wrap individual squares and freeze for up to 3 months. 
• Reheating: Reheat covered in a 300°F oven for 10-12 minutes until warmed through, or air fry slices at 325°F for 3-4 minutes to revive the edges. If frozen, thaw overnight in the fridge or add a minute or two.
