Why You’ll Love This Cheesy Jalapeño Corn Casserole

  • Reliable and foolproof—easy to mix and bake.
  • Feeds a crowd—works well for holiday tables.
  • Sweet, creamy, and cheesy with a mild spicy note from the jalapeño; omit the pepper if you want a milder dish.

Ingredient Notes

  • Jiffy Corn Muffin Mix – Use the original 8.5-ounce mix; avoid flavored varieties.
  • Creamed Corn – Do not drain the can; its liquid helps create the casserole’s creamy texture.
  • Whole Kernel Corn – Any brand is fine; drain this can.
  • Unsalted Butter – Use melted unsalted butter so you can control the dish’s salt level.
  • Sour Cream – Full-fat sour cream gives the best texture and richness.
  • Jalapeño – Remove seeds and membranes for less heat, or skip it entirely.
  • Cheese – Cheddar-Jack is a great choice; sharp cheddar or a blend also works.

How Long Do I Bake It For?

Bake uncovered at 350°F (175°C) for about 45–50 minutes. This casserole should remain moist and slightly loose—not dry and crumbly like traditional cornbread—so avoid overbaking. A lightly golden top and a set center that still looks creamy is perfect.

What Do I Serve This With?

This casserole pairs beautifully with roast turkey, baked ham, mashed potatoes, or mac and cheese. It’s a flexible side that complements classic holiday mains and weeknight dinners alike.

Top Tip

If you prefer a sweeter casserole, stir in a tablespoon or two of granulated sugar or a drizzle of honey before baking. Taste the batter and adjust sweetness to your liking.
