Step 1: Prepare the Ingredients

1. If using canned corn, drain it well and pat it dry with a paper towel. This prevents excess moisture in the dish.
2. If using fresh corn, cut the kernels off the cob and set them aside.

Step 2: Cook the Corn

1. Heat a cast-iron skillet or non-stick pan over medium heat.
2. Add butter and let it melt.
3. Toss in the corn and sauté for 2-3 minutes until heated through and slightly golden.
4. Sprinkle sugar, salt, and black pepper over the corn and stir to combine.

Step 3: Mix in the Creamy Elements

1. Lower the heat and stir in the mayonnaise.
2. If using, add diced onions or garlic powder at this stage for extra flavor.
3. Mix everything well until the corn is evenly coated in a creamy sauce.

Step 4: Add the Cheese

1. Sprinkle shredded mozzarella evenly over the top.
2. If using, add a layer of grated parmesan for extra cheesiness.

Step 5: Melt the Cheese

Option 1 – Stovetop: Cover the pan with a lid and let it cook on low heat for 3-5 minutes until the cheese melts completely.
Option 2 – Broiler: Transfer the skillet to the oven and broil for 2-3 minutes until the cheese turns bubbly and slightly golden.

Step 6: Garnish and Serve

1. Remove from heat and sprinkle chopped green onions on top.
2. If you like a bit of heat, dust with gochugaru for a Korean-inspired spicy touch.
3. Serve hot and enjoy!
