Ingredient Notes

Honey butter cornbread mix - or sweet corn muffin mix. I used Zatarain's Honey Butter Cornbread Mix, however, any sweet mix such as Krusteaz Honey Cornbread Mix, or Jiffy Corn Muffin Mix will work fine.
Corn - use both creamed corn (for sweetness and moisture) and frozen whole kernel corn for added sweetness and texture.
Sour cream - adds creaminess to the casserole and keeps it from getting dry.
Pepper Jack cheese - choose the block of Pepper Jack cheese; look at the ingredients to make sure it has bits of jalapeno in it. Then shred it yourself for the best flavor and creamy texture.
Fresh jalapenos - chopped jalapenos go into the casserole, while sliced jalapenos go on top for even more jalapeno flavor and a little extra heat.
Eggs - binds everything together and gives the casserole a little fluff.
Got extra fresh jalapenos? Use them to make my Jalapeno Bacon Cheese Ball, an easy appetizer that's perfect for holiday parties and family gatherings.
Substitutions
We love this corn casserole as is, but sometimes variations are needed. Here's a list of common ingredient substitutions that work well.
- Shredded cheddar cheese (mild or sharp) instead of Pepper Jack
- Canned whole kernel corn or Mexicorn (one 15.25 oz can, drained) instead of frozen corn.
- Sliced, jarred jalapenos instead of fresh.
What Kind of Corn to Use
This recipe was tested using both canned creamed corn and frozen whole kernel corn. I have not tested this recipe with fresh corn, so keep that in mind.
How to Make Jalapeno Corn Casserole
Photo 1: Mix the butter, cream style corn, frozen corn, cornbread mix, eggs, sour cream, 1 cup of the shredded cheese, black pepper, and chopped jalapenos in a large bowl.

Photo 2: Spread the batter into a baking pan. Sprinkle the remaining cheese all over the top of the casserole. Place the jalapeno slices on top of the cheese.

Photo 3: Bake for 30-45 minutes.

Recipe Tips
Control the heat - remove the seeds and membranes from the chopped jalapenos that go inside the casserole for milder heat. Leave them in the jalapeno slices on top if you want a little extra kick.
Shred your own cheese - buy a block of Pepper Jack cheese and shred it yourself; the flavor and texture is much better than the pre-shredded cheese.

Storing and Reheating
Store leftovers in an airtight container in the refrigerator for up to 3 days. I prefer to use BPA-free glass containers with locking lids. Check out this 18-piece set of glass food storage containers with locking lids from Bayco, available now on Amazon. Reheat in the microwave until nice and hot.
Frequently Asked Questions
This casserole freezes very well! Place leftovers in an airtight container (I place mine into a ziplock bag, squeeze out as much air as possible, and place it into another ziplock bag. Write the date on the bag, and use within 3 months.
The texture of jalapeño corn casserole should be soft and creamy, and slightly firm, but not as firm as regular cornbread. It holds together nicely but isn't stiff or crumbly.
It has a little kick, but you can easily control the heat. Remove the seeds and membranes from the chopped jalapenos that go inside the casserole for milder heat. The jalapeno slices on top can be left seeded for extra heat or deseeded for a milder casserole.
