📝 Ingredients You’ll Need
For the Potato Mixture:
- 2 cups mashed potatoes (leftover or freshly made)
- ½ cup shredded cheese (cheddar, mozzarella, or parmesan)
- ¼ cup finely chopped green onions (or chives)
- 1 egg yolk
- ½ teaspoon salt
- ¼ teaspoon black pepper
- ½ teaspoon garlic powder (optional)
For Breading:
- ½ cup all-purpose flour
- 1 egg (beaten)
- 1 cup breadcrumbs (panko for extra crunch)
For Frying:
- 2 cups vegetable oil (for deep frying)

🔪 Step-by-Step Instructions
Step 1: Prepare the Potato Mixture
- In a large bowl, combine the mashed potatoes, shredded cheese, chopped green onions, egg yolk, salt, black pepper, and garlic powder.
- Mix well until fully incorporated. The mixture should be thick enough to hold its shape when formed into small balls or logs.
- If the mixture feels too soft, you can chill it for 15-20 minutes to firm it up.
Step 2: Shape the Croquettes
- Take about a tablespoon-sized portion of the mixture and roll it into a small ball or oval shape.
- Repeat this process until all the mashed potato mixture is used.
- Place the shaped croquettes on a tray and chill them in the fridge for at least 30 minutes. This helps them hold their shape while frying.
Step 3: Coat the Croquettes
- Prepare three separate bowls:
- Bowl 1: All-purpose flour
- Bowl 2: Beaten egg
- Bowl 3: Breadcrumbs
- Roll each croquette in the flour, dip it in the beaten egg, and coat it in breadcrumbs.
- Repeat this process for all croquettes, ensuring they are evenly coated.
Step 4: Fry the Croquettes
- Heat vegetable oil in a deep pan or fryer to 350°F (175°C).
- Carefully place a few croquettes into the hot oil and fry for about 2-3 minutes per side, or until golden brown and crispy.
- Use a slotted spoon to remove them and place them on a paper towel-lined plate to drain excess oil.
- Repeat until all croquettes are fried.

✨ Tips for the Best Potato Croquettes
- Chill the mixture before frying – This helps prevent the croquettes from falling apart in hot oil.
- Use panko breadcrumbs – They create an extra crispy crust compared to regular breadcrumbs.
- Don’t overcrowd the pan – Fry in small batches to maintain even cooking.
- Oil temperature matters – Keep the oil at 350°F (175°C) for best results.
- Air-fryer option – Cook at 375°F (190°C) for 12-15 minutes, flipping halfway through.
🌟 Delicious Variations
Want to switch things up? Here are some fun variations:
1. Cheese-Stuffed Croquettes
- Insert a small cube of mozzarella into the center of each croquette before shaping for a gooey surprise.
2. Spicy Croquettes
- Add ½ teaspoon of cayenne pepper or finely chopped jalapeños to the potato mixture for a spicy kick.
3. Herb-Infused Croquettes
- Mix in fresh herbs like parsley, basil, or thyme to enhance the flavor.
4. Meat-Filled Croquettes
- Add finely chopped cooked bacon, ham, or shredded chicken to the potato mixture for extra protein.
5. Vegan Croquettes
- Replace the egg yolk with a flax egg and use plant-based cheese for a delicious vegan alternative.
