This cheesy jalapeño corn casserole is creamy, comforting, and made with just seven simple ingredients. It’s an ideal side for Thanksgiving or any special meal—sweet, cheesy, and with a gentle kick from jalapeño (which you can omit if you prefer).

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.
