Ingredients

For approximately 24 Leftover Mashed Potato Cheese Puffs:

• 2 cups (500g) cold leftover mashed potatoes
• 1 cup (120g) shredded sharp cheddar cheese
• 2 large eggs, lightly beaten
• ¼ cup (30g) all-purpose flour
• 3 tablespoons chopped fresh chives
• 2 cloves garlic, minced (about 2 teaspoons)
• ½ teaspoon onion powder
• ¼ teaspoon smoked paprika
• Salt and freshly ground black pepper to taste
• 2 tablespoons (30ml) vegetable oil for pan-frying
• ¼ cup (30g) grated Parmesan cheese (optional, for coating)
• Sour cream or Greek yogurt for serving (optional)

The cold leftover potatoes work best in this recipe as they’ve had time to set and will hold their shape better. Choose a sharp or aged cheddar for maximum flavor impact, though any good melting cheese will work well in these potato puffs.

Pro Tips

1. Temperature Matters: Always start with cold mashed potatoes straight from the refrigerator. Warm potatoes will create a gummy texture and make the puffs difficult to shape. If your potatoes are freshly made, spread them on a baking sheet and chill for at least 2 hours before using.

2. Perfect Your Coating Technique: For the crispiest exterior, try this double-coating method: After shaping your potato cheese puffs, roll them in a light dusting of flour, then dip briefly in beaten egg, and finally coat with a mixture of Parmesan cheese and breadcrumbs. This creates an irresistible golden crust that seals in moisture and adds incredible texture contrast.

3. Oil Temperature Control: Whether you’re pan-frying or air-frying, temperature control is crucial. For pan-frying, heat your oil until a small piece of the potato mixture sizzles immediately upon contact, but doesn’t burn quickly. For best results, maintain a medium heat throughout cooking, adjusting as needed to ensure even browning without burning. This patience ensures your Leftover Mashed Potato Cheese Puffs achieve that perfect golden exterior while heating through completely.

Instructions

Step 1: Prepare Your Mashed Potatoes

Remove your cold leftover mashed potatoes from the refrigerator and place them in a large mixing bowl. Break up any large clumps with a fork to ensure even mixing. If your mashed potatoes are very stiff, you may need to add 1-2 tablespoons of milk to loosen them slightly, but be careful not to make them too soft.

Step 2: Mix Your Base

Add the beaten eggs to your mashed potatoes and mix until well combined. Sprinkle the flour over the mixture and fold it in gently until incorporated. The flour helps bind the puffs and creates a better exterior texture, but overmixing can make them dense, so use a light hand.

Step 3: Add Flavor Boosters

Now for the magic! Fold in the shredded cheddar cheese, chopped chives, minced garlic, onion powder, and smoked paprika. Season with salt and pepper to taste, remembering that your mashed potatoes may already contain some seasoning. The combination of sharp cheese and aromatic seasonings transforms simple potatoes into something extraordinary.

Step 4: Shape Your Puffs

Using a tablespoon or small cookie scoop, portion the mixture and roll into balls approximately 1½ inches in diameter. If the mixture is too sticky to handle, lightly dust your hands with flour or refrigerate the mixture for 30 minutes to firm it up. For an extra crispy coating, roll the balls in grated Parmesan cheese.

Step 5: Cook to Golden Perfection

Heat the vegetable oil in a large skillet over medium heat. Working in batches to avoid crowding, add the potato puffs and flatten them slightly with a spatula. Cook for 2-3 minutes per side until golden brown and crispy. Transfer to a paper towel-lined plate to drain excess oil. Alternatively, place them on a parchment-lined baking sheet and bake at 425°F (220°C) for 18-20 minutes, turning halfway through, until crispy and golden all around.

Step 6: Serve Warm

Arrange your beautiful Leftover Mashed Potato Cheese Puffs on a serving plate while still warm. Garnish with additional chopped chives and serve with a side of sour cream or your favorite dipping sauce. Watch them disappear before your eyes!

Variations

Loaded Baked Potato Puffs: Transform these Leftover Mashed Potato Cheese Puffs into a loaded potato experience by adding 3 tablespoons of cooked, crumbled bacon, 2 tablespoons of finely chopped green onions, and swapping half the cheddar cheese for pepper jack. Top with a dollop of sour cream and extra bacon bits after cooking for the ultimate indulgence.

Mediterranean Potato Puffs: Create a Mediterranean twist by incorporating ¼ cup crumbled feta cheese, 2 tablespoons chopped sun-dried tomatoes, 1 tablespoon chopped fresh oregano, and 1 teaspoon lemon zest into your potato mixture. These bright, tangy mashed potato bites pair beautifully with tzatziki sauce for dipping.

Gluten-Free Option: For those avoiding gluten, simply substitute the all-purpose flour with an equal amount of gluten-free flour blend or corn starch. The texture remains nearly identical, and the flavor is just as delicious. Ensure all other ingredients, including your original mashed potatoes, were prepared without gluten-containing ingredients.

Storage and Serving

Storage: Allow any leftover Leftover Mashed Potato Cheese Puffs to cool completely before storing in an airtight container. They’ll keep in the refrigerator for up to 3 days. For longer storage, freeze the cooked puffs on a baking sheet until solid, then transfer to a freezer-safe bag where they’ll keep for up to 2 months.

Reheating: For the best texture when reheating, avoid the microwave which can make them soggy. Instead, place refrigerated puffs in a 350°F (175°C) oven for 8-10 minutes or air fryer at 325°F (165°C) for 3-4 minutes until heated through and crispy again. Frozen puffs will need an additional 5-7 minutes of cooking time.

Serving Suggestions: Create an impressive appetizer spread by serving these potato cheese puffs alongside other finger foods like chicken wings and vegetable crudités. For a light meal, pair with a crisp green salad dressed with a tangy vinaigrette to balance the richness. They also make an excellent side dish to roasted meats or a hearty soup, elevating a simple meal to something special.
