Ingredients

• 1 (15 ounce) can cream-style corn, undrained
• 1 (15 ounce) can whole kernel corn, drained
• 1 (8.5 ounce) package Jiffy Corn Muffin Mix
• 1 cup sour cream
• 1 cup shredded sharp cheddar cheese, plus extra for topping
• 1/2 cup (1 stick) unsalted butter, melted
• 2 large eggs, lightly beaten
• 1/2 cup milk (whole or 2%)
• 1-2 medium jalapeños, seeds and membranes removed, finely diced (adjust to taste)
• 1/2 teaspoon salt
• 1/4 teaspoon black pepper

Step-by-Step Instructions

1. Preheat your oven to 350°F (175°C). Lightly grease a 9×13 inch baking dish or an 8×8 inch square dish for a thicker casserole.
2. In a large mixing bowl, combine the cream-style corn, drained whole kernel corn, Jiffy Corn Muffin Mix, sour cream, 1 cup of the shredded cheddar cheese, eggs, milk, and melted butter. Stir until just combined; be careful not to overmix.
3. Gently fold in the finely diced jalapeños, salt, and pepper.
4. Pour the batter evenly into the prepared baking dish.
5. Sprinkle the remaining shredded cheddar cheese over the top of the casserole mixture.
6. Bake for 45 to 55 minutes, or until the edges are golden brown and a toothpick inserted near the center comes out clean or with moist crumbs attached.
7. Let the Creamy Cheddar Jalapeno Corn Casserole rest for 5-10 minutes before serving warm.

Expert Tips / Pro Tips

• Manage the Heat: For a milder casserole, ensure you thoroughly remove all white membranes and seeds from the jalapeños. For significantly more heat, leave some of the seeds in, or use an entire jalapeño.
• Room Temperature Eggs: Using room temperature eggs helps the batter emulsify more smoothly, resulting in a more uniform texture.
• Don’t Overmix: Overmixing the muffin mix can develop the gluten too much, leading to a tougher, less tender casserole texture. Mix only until the ingredients are incorporated.
• The Butter Bath: Melting the butter and whisking it directly into the wet ingredients ensures every part of the casserole stays incredibly moist.

Variations & Substitutions

• Cheese Swap: While sharp cheddar is recommended for flavor, Monterey Jack, Pepper Jack (to increase heat further), or a Colby blend work well as substitutes.
• Additions: Feel free to stir in 1/4 cup of chopped green onions or 1/2 cup of cooked, crumbled bacon for extra savory depth.
• Spice Level Control: If you prefer no heat, simply omit the fresh jalapeños, or substitute them with red bell pepper for color and sweetness instead of spice.
• Corn Choice: Frozen corn (thawed) can replace the canned whole kernel corn if preferred.

Serving Suggestions

This rich side dish shines next to smoky mains. It is fantastic served alongside grilled steak, slow-cooked pulled pork, or crispy fried chicken. For an autumn gathering, pair it with roast turkey or ham. A crisp green salad or steamed green beans provide a nice fresh contrast to the casserole’s richness.

Storage, Freezing & Reheating

Storage: Store leftover Creamy Cheddar Jalapeno Corn Casserole in an airtight container in the refrigerator for up to 4 days.

Freezing: This casserole freezes surprisingly well. Cool the baked casserole completely. Slice into individual portions or freeze the entire dish. Wrap tightly in plastic wrap, then foil. Freeze for up to 3 months. Thaw overnight in the refrigerator before reheating.

Reheating: To reheat individual slices, microwave them, covered, in 30-second intervals until hot throughout. To reheat the entire casserole, cover it loosely with foil and bake in a 350°F (175°C) oven for 15-20 minutes, or until heated through.

FAQ

Can I make this casserole ahead of time?

Yes, you can assemble the entire Creamy Cheddar Jalapeno Corn Casserole up to 24 hours in advance. Cover the dish tightly with plastic wrap and refrigerate. When ready to bake, let it sit on the counter for about 20-30 minutes to take the chill off, or add about 10-15 minutes to the total bake time.

What does the Jiffy mix do in this recipe?

The corn muffin mix acts as the essential binder and structure for the casserole, much like flour or cornmeal would, but it adds the pre-seasoned flavor and sweetness of a standard corn bread mix, ensuring a tender final product.

How spicy will this actually be?

If you use one medium jalapeño with the seeds removed, the spice level is generally mild to medium—enough to notice a pleasant warmth without overwhelming the cheesy flavor. If you are sensitive to spice, use only half a pepper or substitute bell pepper.
