Step 1: Preheat and Prep

Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish or a deep 2-quart casserole dish with non-stick spray or butter.

Step 2: Mix Wet Ingredients

In a large mixing bowl, whisk together the eggs, melted butter, sour cream, whole corn, and creamed corn.

Step 3: Add Dry Ingredients

Add the corn muffin mix, garlic powder, onion powder, salt, and pepper to the wet mixture. Stir until just combined—don’t overmix.

Step 4: Stir in Jalapeños and Cheese

Fold in the chopped jalapeños, shredded cheese, and green onions if using. Reserve a handful of cheese for topping.

Step 5: Bake

Pour the mixture into the prepared baking dish and smooth the top. Sprinkle with the remaining cheese.

Bake for 45–50 minutes, or until the top is golden and the center is set. A toothpick inserted should come out mostly clean.

Step 6: Cool and Serve

Let the bake rest for 5–10 minutes before serving. This allows the cheesy center to firm up slightly, making it easier to slice.
