This creamy, cheesy corn casserole with a kick of jalapeño is the perfect potluck or holiday side dish. It comes together in under 30 minutes with simple ingredients and is always a crowd-pleaser.
For a gluten-free version, omit panko topping or use gluten-free breadcrumbs. To control heat, use only pickled jalapeños for milder flavor, or leave seeds in fresh jalapeño for more heat. Assemble up to 24 hours ahead (without panko) and refrigerate; add panko and bake as directed, adding 5-10 minutes. If top browns too quickly, tent with foil.
