Step 1: Preheat the Oven

Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper and lightly grease it with cooking spray or olive oil to prevent sticking.

Step 2: Prepare the Mixture

In a large bowl, mix the mashed potatoes, cheddar cheese, Parmesan cheese, green onions (if using), garlic powder, onion powder, black pepper, and salt until everything is well combined.

Step 3: Form the Balls

Scoop out about 1-2 tablespoons of the potato mixture. Using your hands, roll it into a ball. Repeat this process until all the mixture is used.

Step 4: Coat the Balls

Set up three bowls to make a breading station: one with flour, one with beaten eggs, and another with breadcrumbs. Roll each ball in flour, dip in the egg, then coat thoroughly with breadcrumbs.

Step 5: Bake

Arrange the coated balls on the prepared baking sheet. Spray the tops lightly with cooking spray or drizzle with olive oil to enhance crispiness. Bake for 20-25 minutes, flipping halfway through, until golden brown and crispy.

Step 6: Serve

Let the cheese balls cool slightly before serving. They are best enjoyed warm with your favorite dipping sauce, such as ranch dressing, marinara, or a spicy aioli.

Variation

• Spicy Version: Add diced jalapeños or a pinch of cayenne pepper to the potato mixture for a spicy kick.
• Cheese Varieties: Experiment with different types of cheese such as mozzarella or smoked gouda for different flavors.
