Ingredients

Scale
  • 4 tablespoons unsalted butter, melted
  • 2 (15-ounce) cans whole kernel corn, drained
  • 1 cup sour cream
  • ¼ cup mayonnaise
  • 1 cup shredded cheddar cheese
  • 1 cup shredded Monterey Jack cheese
  • 1 large jalapeño, seeds and membranes removed, finely diced
  • 2 large eggs, lightly beaten
  • 1 tablespoon granulated sugar
  • ½ teaspoon salt
  • ¼ teaspoon black pepper
  • Optional: extra shredded cheese and jalapeño slices for topping

Instructions

  1. Preheat oven to 350°F (175°C). Place butter in an 8×8 or 9×9 baking dish and put it in the oven to melt. Once melted, swirl to coat the bottom.
  2. Drain the canned corn well in a colander, pressing out excess liquid.
  3. In a large mixing bowl, whisk together sour cream, mayonnaise, and beaten eggs until smooth.
  4. Add drained corn, 1 cup cheddar, 1 cup Monterey Jack, diced jalapeño, sugar, salt, and pepper. Stir until evenly combined.
  5. Pour mixture into the prepared baking dish and spread into an even layer.
  6. Sprinkle remaining ½ cup cheddar cheese on top. Add optional jalapeño slices if desired.
  7. Bake for 25 to 30 minutes, until edges are golden and bubbly and center is set (not jiggly). For a darker top, broil for 1–2 minutes, watching closely.
  8. Let rest for 5 to 10 minutes before serving.

Notes

For a spicier version, keep some jalapeño seeds. For a milder version, use half a jalapeño or substitute with canned diced green chiles. To make ahead, assemble and refrigerate up to 24 hours; add 10 minutes to baking time. Leftovers keep in the fridge for up to 4 days and can be frozen for up to 3 months.
