Ingredients for Leftover Mashed Potato Cheese Puffs

To make these Leftover Mashed Potato Cheese Puffs, you’ll need the following ingredients:

2 cups leftover mashed potatoes (or about 3-4 medium potatoes if you’re making them fresh)
1/2 cup shredded cheddar cheese (or your favorite cheese)
1/4 cup breadcrumbs
1/4 cup grated parmesan cheese
1 egg
1/4 teaspoon garlic powder
1/4 teaspoon onion powder
Salt and pepper, to taste
1 tablespoon fresh parsley (optional, for garnish)
Olive oil or butter, for greasing the baking sheet

These ingredients come together to create cheesy, golden puffs that are full of flavor and texture.

Step-by-Step Instructions for Leftover Mashed Potato Cheese Puffs

Step 1: Preheat the Oven

Preheat your oven to 375°F (190°C). Line a baking sheet with parchment paper or lightly grease it with olive oil or butter to prevent the puffs from sticking.

Step 2: Mix the Mashed Potatoes

In a large bowl, combine your leftover mashed potatoes with shredded cheddar cheese, parmesan cheese, breadcrumbs, and the egg. Stir everything together until the mixture is smooth and evenly combined. Season with garlic powder, onion powder, salt, and pepper to taste.

If the mixture feels too sticky or wet, you can add a little extra breadcrumbs until it holds its shape better.

Step 3: Form the Puffs

Using your hands or a spoon, scoop out small portions of the mashed potato mixture and roll them into small balls (about the size of a golf ball). Place each ball onto the prepared baking sheet, leaving a little space between each one.

For an even crispier finish, you can slightly flatten each ball to create a disc-like shape.

Step 4: Bake the Cheese Puffs

Bake the potato cheese puffs in the preheated oven for about 20-25 minutes, or until they’re golden brown and crispy on the outside. For an extra golden color, you can broil them for the last 1-2 minutes of cooking, but keep a close eye on them to avoid burning.

Step 5: Serve and Enjoy

Once baked, remove the puffs from the oven and let them cool for a few minutes before serving. Garnish with some fresh parsley if desired, and enjoy these cheesy, crispy potato puffs as a snack, side dish, or appetizer!

Reheating: To reheat, simply place the puffs on a baking sheet and warm them in the oven at 350°F (175°C) for about 10-12 minutes, or until they’re crispy again. You can also reheat them in the microwave for a quicker option, but the texture may not be as crispy.

Common Mistakes to Avoid When Making Leftover Mashed Potato Cheese Puffs

Not drying out the potatoes: Make sure your leftover mashed potatoes aren’t too watery. If needed, press them with a paper towel to absorb excess moisture before mixing with the other ingredients.
Overcrowding the baking sheet: Leave some space between the puffs on the baking sheet to allow them to cook evenly and become crispy on all sides.
Underbaking the puffs: These puffs need enough time in the oven to develop a crispy, golden exterior. Make sure to bake them for the full time recommended.

By avoiding these mistakes, you’ll ensure your cheese puffs come out perfectly every time!
