Ingredients
Scale
- 1 box (8.5 oz) Jiffy Corn Muffin Mix
- 1 can (15.25 oz) whole kernel corn, drained
- 1 can (14.75 oz) cream-style corn
- 1 cup sour cream (full-fat recommended)
- 1/2 cup unsalted butter, melted
- 2 large eggs, lightly beaten (room temperature)
- 2 cups shredded sharp cheddar cheese, divided
- 1/2 cup pickled jalapeño slices, chopped
- 1 fresh jalapeño, seeded and minced (optional)
- 1 teaspoon garlic powder
- 1/2 teaspoon black pepper
- 1/4 teaspoon smoked paprika
Instructions
- Preheat oven to 350°F (175°C). Grease a 9×13-inch baking dish with butter or non-stick spray.
- Prep ingredients: Drain whole kernel corn, chop pickled jalapeños, seed and mince fresh jalapeño (if using), grate cheese, and beat eggs in a small bowl.
- In a large mixing bowl, combine melted butter, sour cream, and beaten eggs. Whisk until smooth.
- Stir in drained whole kernel corn and cream-style corn until evenly distributed.
- Add Jiffy corn muffin mix, garlic powder, black pepper, and smoked paprika. Stir until just combined (a few lumps are fine).
- Gently fold in 1 cup shredded cheddar cheese and chopped pickled jalapeños (and fresh jalapeño, if using).
- Pour batter into prepared baking dish and spread evenly. Tap dish gently on counter to settle.
- Sprinkle remaining 1 cup shredded cheddar evenly over the top.
- Bake for 40-45 minutes, until edges are golden brown and center is set (toothpick inserted in center comes out clean or with a few moist crumbs).
- Let casserole rest for at least 10 minutes before cutting and serving.
Notes
Don’t overmix the batter to keep the casserole tender. Room temperature ingredients blend better. Freshly grated cheese melts more smoothly. Let the casserole rest for 10 minutes before serving to set properly. For a spicier version, leave seeds in fresh jalapeño. For a milder version, omit jalapeños and use diced green chiles.
