Take the chilled double cheddar macaroni and cheese and scoop out small portions to form balls. Use your hands to shape them into compact balls.
In three separate bowls, set up a coating station.
Bowl 1: All-purpose flour
Bowl 2: Mixture of beaten eggs and milk
Bowl 3: Panko bread crumbs mixed with grated Parmesan cheese, granulated garlic, onion powder, salt, and black pepper. Add hot sauce if desired.
Roll each mac and cheese ball in the flour, ensuring it's evenly coated.
Dip the floured ball into the egg and milk mixture, covering it completely.
Roll the ball in the seasoned panko and Parmesan mixture, pressing the crumbs onto the ball to adhere.
For an extra crispy coating, repeat the process by dipping the ball back into the egg and milk mixture and then rolling it again in the panko mixture.
In a deep fryer or a large, deep pan, heat vegetable, canola, or peanut oil to 350°F (175°C).
Carefully place the coated mac and cheese balls into the hot oil using a slotted spoon or tongs.
Fry until they turn golden brown and crispy, usually 2-3 minutes. Ensure they are cooked evenly.
Remove the fried mac and cheese balls and place them on paper towels to drain excess oil.
Garnish with chopped green onions, chives, or parsley for added freshness.
Serve the Fried Mac and Cheese Balls hot and enjoy them as a delicious appetizer or snack.
