Easy Cornbread Casserole Recipe

This is not plain cornbread, and it is not corn pudding either — this cornbread casserole is the best of both. It slices into thick, tall squares with a fluffy, moist center full of sweet corn, tender onion and melted cheddar, and the top bakes into a deep golden, almost crispy cheese crust. Look at that slice in the photo: that is what two boxes of mix, real cheese and the right pan will do for you.

What makes it a casserole instead of a bread? The creamed corn and sour cream keep the crumb soft and rich, while a full cup of cheddar melts right through the batter — and another layer of cheese on top turns into that bronzed crust everyone fights over. It goes from one mixing bowl to the holiday table in about an hour, and it is just as welcome next to a bowl of chili on a Tuesday.

Why This Cornbread Casserole Beats Plain Cornbread

• Thick, tall slices — two boxes of mix in a 9×13 dish give you a real slab you can slice and stack, not a thin, sad layer.
• Cheese in every layer — cheddar folded through the batter AND baked on top, so you get melty pockets inside and a crispy golden crust outside.
• Fluffy and moist, never dry — creamed corn and sour cream keep the crumb tender for days, even reheated.
• One bowl, no mixer — stir it together in five minutes; the oven does everything else.
• Dresses up or down — holiday-worthy next to turkey and ham, and the single best thing to serve under a spoonful of chili or pulled pork.

The Ingredients (Pantry Staples, Big Payoff)

• 2 boxes (8.5 oz each) Jiffy corn muffin mix — using two boxes is the secret to the thick, lofty slices in the photo. One box in a big pan bakes up thin and dry.
• 1 can (14.75 oz) creamed corn, not drained — the moisture backbone. It keeps the center soft and sweet.
• 1 can (15 oz) whole kernel corn, drained — pops of real corn texture in every bite. Drain it well so the batter stays rich, not wet.
• 1 cup sour cream — tang and tenderness. Full-fat, please; Greek yogurt is an acceptable swap.
• 1/2 cup (1 stick) butter, melted — flavor, and it helps those edges turn crisp and golden.
• 2 large eggs — lift and structure, so the casserole rises fluffy instead of dense.
• 1/3 cup milk — loosens the double batch of batter to just the right pourable consistency.
• 1 small yellow onion, finely diced — the savory little pieces you can see tucked through the crumb in the photo. Dice it small so it softens completely as it bakes.
• 2 cups shredded sharp cheddar cheese, divided — 1 1/2 cups go into the batter, and the last 1/2 cup blankets the top and bakes into that deep golden crust.
• 1/2 teaspoon garlic powder — quiet background savoriness. Optional, but it makes people ask what your secret is.
• 1/4 teaspoon black pepper
• 3 green onions, thinly sliced — for scattering over the top after baking, exactly like the photo. Fresh, bright, and it makes the whole dish look finished.

How to Make It: One Bowl to Golden Crust

1. Heat the oven. Preheat to 350°F (175°C). Grease a 9×13-inch baking dish well with butter or cooking spray — the cheesy edges love to stick, so be generous in the corners.
2. Melt the butter. Melt the butter and let it cool for a minute or two so it does not scramble the eggs on contact.
3. Whisk the wet base. In a large mixing bowl, whisk together the eggs, milk and sour cream until smooth. Whisk in the melted butter.
4. Add the corn and onion. Stir in the creamed corn (with all its liquid), the drained whole kernel corn, and the finely diced onion.
5. Fold in the mix and cheese. Add both boxes of Jiffy mix, the garlic powder and the pepper. Stir just until combined — a few lumps are fine. Then fold in 1 1/2 cups of the cheddar.
6. Fill the dish. Pour the batter into the prepared dish and smooth it into the corners. Let it rest on the counter for 5 minutes; this little pause lets the mix hydrate and gives you a more even rise.
7. Top with cheese. Sprinkle the remaining 1/2 cup of cheddar evenly over the surface, all the way to the edges.
8. Bake until the crust is deep gold. Bake for 40 to 45 minutes, until the top is a rich golden brown with bronzed edges, the center is set, and a toothpick in the middle comes out clean or with a few moist crumbs. If the top browns faster than the center sets, lay a loose sheet of foil over it for the last 10 minutes.
9. Rest, garnish, serve. Rest for 10 minutes — the slices cut far more cleanly. Scatter the sliced green onions over the top and serve warm.

Sofia’s Expert Tips (Tall, Fluffy, Golden)

• Two boxes, always, for a 9×13. The most common cornbread casserole disappointment is a thin, dry slab. Doubling the mix to match the pan is what gives you that thick, bakery-style slice.
• Dice the onion truly fine. Big chunks of onion stay crunchy and sharp inside a tender crumb. Pieces no bigger than a corn kernel soften and turn sweet as they bake.
• Do not overmix the batter. Cornmeal batters toughen when stirred too much. Mix until the dry streaks disappear, then stop — lumps are not the enemy, density is.
• The top cheese is a crust, not a garnish. Spread it edge to edge and let it bake the full time. That bronzed, slightly crisp cheese layer is the signature of this casserole — pale and patchy means it came out too soon.
• Rest before you slice. Ten minutes of patience lets the crumb finish setting. Cut too early and the squares slump; wait, and they stand up tall like the photo.

Easy Variations to Try

• Mexican-style: swap the cheddar for pepper jack, stir in a drained 4 oz can of diced green chiles and 1/2 teaspoon of cumin, and finish with cilantro instead of green onions.
• Jalapeño popper: fold in 2 finely diced jalapeños and 1/2 cup of crumbled cooked bacon, and use a blend of cheddar and cream-cheese dollops through the batter.
• Honey butter finish: brush the hot top with 2 tablespoons of melted butter whisked with 1 tablespoon of honey for a sweet-savory shine.
• Loaded veggie: add 1 cup of finely diced bell pepper and a handful of chopped spinach for color and a little freshness in every square.

How to Store, Freeze and Reheat It

• Fridge: cover the dish or store squares in an airtight container for up to 4 days. The crumb stays moist thanks to the creamed corn.
• Reheat: a 350°F (175°C) oven for 10 to 15 minutes brings back the crispy top and melty middle. The microwave revives a square in about a minute — softer top, still delicious, especially under chili.
• Freezer: bake, cool completely, and freeze whole or in individual squares, well wrapped, for up to 3 months. Thaw overnight in the fridge and reheat in the oven until hot and crisped on top again.
