Ingredients for summer potluck corn casserole crowd

• 4 cups corn kernels (fresh, frozen, or canned)
• 1 cup sour cream
• 1 cup mayonnaise
• 1 cup sharp cheddar cheese, shredded
• 1/2 cup parmesan cheese, grated
• 4 tbsp butter
• 1 medium onion, diced
• 3 cloves garlic, minced
• 1 tsp salt
• 1/2 tsp black pepper
• 1/2 tsp paprika
• 2 tbsp fresh chives, chopped
• 1 cup panko breadcrumbs
• 2 tbsp melted butter
• 1/4 cup parmesan cheese for topping

For substitutions, use Greek yogurt in place of sour cream for a lighter version, or swap mayo with additional sour cream if preferred. Fresh corn kernels deliver the best flavor, but frozen corn works beautifully year-round and saves prep time. If sharp cheddar isn’t available, extra-sharp or aged cheddar creates even more depth. Freshly grated cheese melts more smoothly than pre-shredded varieties, so this investment makes a noticeable difference in texture. For a spicy kick, add diced jalapeños or cayenne pepper to the base mixture.

Step-by-step crowd potluck corn instructions

1. Preheat your oven to 350°F and lightly grease a 9×13-inch baking dish with butter or cooking spray. Having your dish ready before mixing ingredients keeps the assembly process smooth and efficient.

2. Melt 4 tablespoons butter in a large skillet over medium heat, then add the diced onion and sauté for 3-4 minutes until softened. Add minced garlic and cook for another 30 seconds until fragrant, being careful not to burn it.

3. Stir in all 4 cups of corn kernels and cook for 2 minutes, allowing the flavors to meld together. Remove from heat and let cool slightly before combining with other ingredients.

4. In a large mixing bowl, combine sour cream and mayonnaise until well blended. Add the sharp cheddar cheese, 1/2 cup parmesan cheese, salt, pepper, and paprika, stirring until everything is evenly distributed throughout this summer potluck corn casserole crowd favorite.

5. Fold the cooled corn mixture into the cheese mixture gently but thoroughly, being careful not to crush the kernels. Stir in fresh chopped chives for a bright, fresh finish.

6. Transfer the creamy corn mixture to your prepared baking dish and spread evenly. In a small bowl, combine panko breadcrumbs with 2 tablespoons melted butter and 1/4 cup parmesan cheese, then sprinkle evenly over the top.

7. Bake for 30-35 minutes until the topping is golden brown and the edges are bubbling slightly. The casserole should be heated through completely and the panko should have a deep golden color.
