Peel and cut the potato into small cub-like pieces
Boil the water. Enough water to cover the entire potato cubes. Cook the potato for 15 minutes until the potato cubes are soft.
Drain the boiled water and then mash the potato while it is hot.
Next, we make white cream sauce. Melt the butter first in low to medium heat. Then add finely diced onion once the butter is fully melted. Cook for 5 minutes until the onion is soft. Stir constantly, so the onion wont get burned. Add flour, then stir. Add milk. Continue stiring until the sauce has thickend. Add chicken broth powder, salt, pepper, and a can of corn.
Combine mashed potato with the white cream mixture. Put the mixture in the friege and wait for at least 30 minutes - 1 hr for the mixture to cool off before making the coroquette balls because that way it is easier to form the croquette balls.If you have time, I recomend to make the mixture a night before.
Next, let's make croquette batter.Prepare 2 separate plates, one plate with ⅓ cup flour, and another plate with panko. Beat 2 large eggs in a bowl, then add ⅓ cup flour. Combine egg and flour well. If the batter is too thick, add some water. Scoop out a few balls of the croquette mixture and place them on the plate with flour. Flatten them a bit with your hands, use flour so the mixture dose not stick to your skin.
Dip the round croquette balls into the egg batter. Cover them in panko next.
Heat up the oil in the deep frying pot. Set the stove at medium-high heat. To know when the oil is ready, drip a piece of panko in and if it immediatrly rises , ou can start frying process.
Fry the croquettes until they are golden brown. It takes a few minutes. Avoid over frying becuase the croquettes will explode and burn. Place the cooked croquettes on a plate with a paper towel. The paper towel will drain the excess oil and make the croquette crisper.
Serve with your favorite salada on the side.
