Step 1

Preheat and Prepare: Turn your oven to 350°F. Lightly grease a 9-by-13-inch baking dish with butter.

Step 2

Cook Onion and Peppers: In a large skillet, melt the butter over medium heat. Add the chopped onion and cook until it softens, which takes about 8 minutes. Add the jalapeños and garlic, stirring for about 2 minutes until they release their aroma.

Step 3

Add Corn: Stir in the corn kernels and cook them until they are just tender, about 4 minutes. Move this mixture to a large bowl.

Step 4

Combine Ingredients: To the bowl with the onion and corn, add sour cream, creamed corn, corn muffin mix, beaten eggs, and salt. Mix everything well.

Step 5

Bake and Serve: Pour the mixture into your greased baking dish, spreading it evenly. Bake for 50 to 60 minutes until the top is lightly browned and the center is puffed up. Let it cool for 5 minutes before serving.
