This cheesy jalapeno corn casserole is a creamy, cheesy side dish with a little heat! It’s a true crowd-pleaser and the perfect dish for the holidays!
Every year, my mom makes the best jalapeno corn casserole for Thanksgiving. It has become one of our family’s favorite side dishes! She usually makes 2 big baking pans— one spicy version with jalapenos and one without, for those who can’t handle the heat. The spicy one is always everyone’s favorite and the first one to run out first.
This recipe was as closest as I could get to my mom’s version because lets be honest — moms don’t really use exact measurements. At least my mom doesn’t 😅
What you’ll need to make Cheesy Jalapeno Corn Casserole:
- Cream-style corn: I use canned cream-style corn, this adds the perfect amount of creaminess and moisture to the casserole.
- Whole-kernel corn: I use canned whole-kernel corn because corn isn’t in season right now, but feel free to use fresh corn if you have some on hand!
- Jiffy corn muffin mix: Corn muffin mix helps bind the casserole together and gives it more body because this version is more creamy and rich.
- Unsalted butter: I used unsalted since all the shredded cheese adds enough saltiness for me, but I can’t imagine it behind a huge difference if you only have salted butter at home. This recipe doesn’t use too much butter, so any kind should work!
- Onion: diced onions add another layer of sweetness that you can’t get from corn and a little crunchy bite!
- Jalapeno peppers: this recipe uses 1-2 jalapeno peppers, but you can adjust the amount depending on how spicy you like it.
- Egg: this is another binding agent that helps bring together the whole dish and keeps it from being too runny.
- Shredded cheese: when it comes to cheese, the choice is yours! I like to use a mix of sharp cheddar and mozzarella.
