Ingredients

Scale
  • 1 can (15 oz) whole kernel corn, drained
  • 1 can (15 oz) creamed corn
  • 1 cup shredded cheddar cheese (sharp or mild)
  • 1 cup sour cream (full-fat or light)
  • 1/2 cup unsalted butter, melted
  • 2 large eggs, room temperature
  • 1 box (8.5 oz) corn muffin mix (e.g., Jiffy)
  • 2 scallions, thinly sliced (optional)
  • 1/2 tsp salt
  • 1/4 tsp black pepper
  • Optional: 1/2 cup diced roasted red peppers
  • Optional: 1 small jalapeño, seeded and minced
  • Optional: 1/4 cup chopped fresh parsley

Instructions

  1. Preheat oven to 350°F (175°C). Grease a 9×13-inch baking dish with butter or nonstick spray.
  2. In a medium bowl, whisk together sour cream, eggs, and melted butter until smooth.
  3. Stir in whole kernel corn (drained) and creamed corn. Mix gently.
  4. Add corn muffin mix and fold until just combined. Do not overmix.
  5. Stir in shredded cheddar cheese, sliced scallions, salt, and black pepper. Add optional ingredients if desired.
  6. Pour mixture into prepared baking dish and smooth the top.
  7. Bake uncovered for 40-45 minutes, until edges are golden brown and center is just set. Tent with foil if top browns too quickly.
  8. Check doneness with a toothpick near the center; it should come out mostly clean.
  9. Let casserole rest for at least 10 minutes before serving.

Notes

For gluten-free, use a certified gluten-free corn muffin mix. For dairy-free, substitute vegan butter, plant-based sour cream, and dairy-free cheddar. Do not overmix the batter to avoid a dense texture. Bake uncovered for a crispy top, and let rest before serving for easier slicing. Fresh corn kernels can be used in summer for extra crunch. Casserole can be made ahead and refrigerated before baking.
