easy cheesy corn casserole with jalapeño - featured image

A quick and easy corn casserole with a cheesy, creamy texture and a pop of heat from jalapeño. Perfect for weeknights or potlucks, ready in just 15 minutes of prep.

Ingredients

Scale
  • 1 can (15.25 oz) whole kernel corn, drained
  • 1 can (14.75 oz) creamed corn
  • 1 box (8.5 oz) Jiffy corn muffin mix
  • 1 cup sour cream
  • 1/2 cup unsalted butter, melted
  • 2 large eggs, lightly beaten
  • 1 1/2 cups shredded cheddar cheese, divided
  • 1 fresh jalapeño, seeded and finely diced
  • 1/4 teaspoon salt
  • 1/4 teaspoon black pepper
  • Extra shredded cheese for the top (optional)
  • Thinly sliced jalapeño rounds (optional)
  • Chopped fresh cilantro (optional)

Instructions

  1. Preheat your oven to 350°F (175°C). Grease an 8×8-inch baking dish with butter or non-stick spray.
  2. Drain the can of whole kernel corn in a colander and set aside.
  3. In a large mixing bowl, whisk together the sour cream, melted butter, and beaten eggs until smooth and creamy.
  4. Add the drained whole kernel corn, creamed corn, and corn muffin mix. Stir with a wooden spoon until just combined (a few lumps are fine).
  5. Fold in 1 cup of the shredded cheddar cheese and the diced jalapeño. Stir gently until distributed.
  6. Add the salt and pepper, and give one more gentle stir.
  7. Pour the batter into the prepared baking dish and spread evenly.
  8. Sprinkle the remaining 1/2 cup of shredded cheese over the top. Add optional jalapeño slices if desired.
  9. Bake for 40-45 minutes, until the edges are golden brown and the center is set (not jiggly). A toothpick inserted in the center should come out clean or with a few moist crumbs.
  10. Let the casserole rest for 5-10 minutes before serving.

Notes

For a milder version, use only half the jalapeño or substitute canned diced green chiles. Toasting the jalapeño in a dry skillet for 1-2 minutes before adding can deepen the flavor. The casserole can be assembled the night before and refrigerated; add 5-10 minutes to the baking time. Double the recipe for a 9×13 dish and bake for 45-50 minutes.
