Set your oven to 180°C (350°F). Let it heat fully before baking. A preheated oven helps cook the casserole evenly. Lightly grease your baking dish with butter so nothing sticks later.

If using fresh corn, remove kernels from the cob. For frozen corn, thaw it first. If using canned corn, drain all liquid. Keep the corn ready in a bowl before mixing.

Place cream cheese in a bowl at room temperature. Soft cream cheese mixes easily. You can also microwave it for a few seconds if needed. Do not melt it fully.

Add cream cheese, milk and butter to a mixing bowl. Stir well until smooth and creamy. This forms the base of your Cream Cheese Corn Casserole Recipe.

Add corn into the creamy mixture. Then add salt, pepper, garlic powder, and sugar. Mix everything well so the corn gets fully coated with the creamy base.

Now add shredded cheddar cheese. Mix gently so it spreads evenly. The cheese will melt during baking and make the casserole rich and delicious.

Pour the mixture into the greased baking dish. Spread it evenly with a spoon. Make sure the top is smooth so it bakes evenly.

Place the dish in the oven. Bake for 35–40 minutes. The top should turn light golden. The edges may bubble slightly, which means it is ready.

Remove from oven and let it cool for 5–10 minutes. This helps the casserole set. Sprinkle green onions on top before serving for a fresh look.
