Step-by-Step Instructions

Step 1: Prepare the Mixture

  1. In a large mixing bowl, combine:

    • Mashed potatoes

    • Shredded cheddar cheese

    • Breadcrumbs

    • Egg

    • Garlic powder, onion powder, parsley, salt, and pepper

  1. Scoop about 1 tablespoon of the mixture and roll it into a ball.

  2. Place each ball on a tray or plate.

  3. (Optional) For an extra crispy coating, roll the puffs in additional breadcrumbs or panko before frying.

Step 3: Fry the Puffs

  1. Heat a few tablespoons of olive oil in a frying pan over medium heat.

  2. Once the oil is hot, carefully place the potato puffs in the pan.

  3. Fry for 2-3 minutes per side, or until golden brown and crispy.

  4. Use tongs or a slotted spoon to turn them gently.

  5. Once done, transfer to a paper towel-lined plate to drain excess oil.

Step 4: Serve and Enjoy!

  • Serve the potato cheese puffs hot, with your favorite dipping sauce!

  • Enjoy as a snack, side dish, or appetizer.

How to Cook These Without Frying

If you prefer a healthier alternative, try these cooking methods:

🔹 Air Fryer – Preheat to 375°F (190°C), place puffs in a single layer, and air fry for 10-12 minutes, shaking halfway through.
🔹 Oven Baking – Preheat to 400°F (200°C), place on a greased baking sheet, and bake for 15-20 minutes, flipping halfway through.

Both methods result in a crispy exterior with less oil!
