This Jalapeño Cornbread Casserole is one of my favorite ways to bring a little heat to a comfort classic. It starts with a box of Jiffy, gets a flavor boost from creamed corn, and finishes with chopped jalapeños and melted cheddar cheese baked right in.

Jump to Recipe

It’s the kind of fall cornbread recipe that feels familiar but just different enough to keep things interesting.

I usually serve this as a side with chili or roasted meats, but it also works on its own with a little butter or honey on top. You can make it as mild or as spicy as you want by adjusting the jalapeños, and it reheats well for leftovers.

If you like jalapeño cheddar cornbread, this casserole version gives you the same flavors with a softer, more spoonable texture. It comes together in one bowl with eight ingredients and bakes in a single 8×8 inch dish.

Why This Jalapeño Cornbread Casserole Works

Plain boxed cornbread can be dry and crumbly. This recipe fixes that with two extras. Creamed corn adds moisture and little bursts of sweet corn in every bite. Sour cream makes the batter richer and keeps the center tender, almost like a cross between cornbread and corn pudding. The melted butter and egg hold it together so you can still cut it into squares.

The jalapeños and cheddar balance the sweetness of the Jiffy mix and the corn. Folding most of the cheese into the batter gives you melty pockets throughout, and saving a handful for the top gives you a golden, slightly crisp crust.

Ingredients and Easy Swaps

Jiffy cornbread mix. One 8.5 ounce box is the base. Any brand of sweet corn muffin mix in a similar size works the same way.

Creamed corn. A 15 ounce can is all you need. Don’t drain it. If you’d like more texture, add 1/2 cup of drained whole kernel corn along with it.

Sour cream. Plain Greek yogurt is an easy swap and gives a slightly tangier flavor.

Jalapeños. Use 1 jalapeño for mild heat and 2 for more kick. Most of the heat lives in the seeds and white ribs, so scrape those out for a milder casserole or leave them in if you like it hot. Canned diced green chiles are a good option for kids or anyone who doesn’t like spice.

Cheddar. Sharp cheddar has the most flavor. Pepper jack or a Mexican cheese blend also work well.

How to Make It at a Glance

1. Heat the oven to 375°F and grease an 8×8 inch baking dish.
2. Mix the cornbread mix, sour cream, melted butter, and egg in a large bowl.
3. Stir in the creamed corn, then fold in the jalapeños and most of the cheese.
4. Pour into the dish and top with the rest of the cheese and a few jalapeño slices.
5. Bake 30 to 35 minutes, until golden and set, then cool slightly before slicing.

Common Mistakes to Avoid

Overmixing the batter. Stir just until you don’t see dry streaks of mix. Too much stirring makes the casserole dense and gummy.

Pulling it out too soon. The top can look golden before the middle is cooked. The center should look set and only jiggle slightly when you shake the pan. A toothpick in the middle should come out with a few moist crumbs, not wet batter.

Slicing it hot. Give it about 10 minutes on the counter. It firms up as it cools and cuts into much cleaner squares.

Rubbing your eyes after chopping jalapeños. Pepper oils stay on your skin. Wash your hands well with soap, or wear gloves while you chop.

Variations

Add bacon. Stir 4 slices of cooked, crumbled bacon into the batter with the cheese.

Honey butter top. Brush the warm casserole with 2 tablespoons of melted butter mixed with 1 tablespoon of honey right after it comes out of the oven.

Green chile version. Swap the jalapeños for one 4 ounce can of diced green chiles for a mild, family-friendly flavor.

Make a bigger batch. Double everything and bake in a 9×13 inch dish. Start checking at 35 minutes, since it may need up to 45.

What to Serve With It

Chili is the classic match, and a square of this casserole on the side of a bowl of beef or white chicken chili is hard to beat. It’s also great with barbecue, pulled pork, fried chicken, or a holiday turkey. For a cozy fall dinner, serve it next to these crockpot apple cinnamon pork chops. The sweet corn and mild heat go well with the cider sauce.

Frequently Asked Questions

Is this casserole very spicy?
Not with the seeds removed. One seeded jalapeño gives a mild warmth that most kids can handle. Leave the seeds in or add a second pepper if you want more heat.

Can I use fresh corn instead of creamed corn?
Creamed corn adds moisture that fresh kernels don’t. If you use fresh or frozen kernels, add an extra 1/4 cup of sour cream so the casserole doesn’t turn out dry.

Can I freeze jalapeño cornbread casserole?
Yes. Cool it completely, wrap it tightly in plastic wrap and foil, and freeze for up to 3 months. Thaw overnight in the fridge and reheat in a 300°F oven.

Make-Ahead Tip

Prepare the casserole up to the baking step, cover tightly, and refrigerate for up to 24 hours. When ready to bake, let it sit on the counter for 15 to 20 minutes while the oven preheats. Bake as directed, adding 5 to 10 extra minutes if needed. The center should be set before you take it out.

Leftovers Reheat Well

Store cooked casserole covered in the fridge for up to 3 days. Reheat individual slices in the microwave for 30 to 45 seconds, or cover the full dish with foil and warm it in a 300°F oven for 15 to 20 minutes, until heated through. The foil keeps the edges from drying out. For longer storage, freeze it for up to 3 months.
