Ingredients

One of the best things about this recipe is how simple and familiar the ingredients are. Each one plays an important role in creating the perfect texture and flavor.

• Leftover mashed potatoes – Provide moisture, structure, and that creamy base we love

• Cheddar cheese – Adds sharp flavor and a melty, gooey texture

• Parmesan cheese – Brings savory depth and helps create crisp edges

• Eggs – Bind everything together and give the puffs a light lift

• All-purpose flour – Adds stability so the puffs hold their shape

• Chives or green onions – A fresh, mild onion flavor that brightens each bite

• Garlic powder – Subtle seasoning without overpowering

• Black pepper & salt – Balance and enhance all the flavors

• Cooking spray or oil – Encourages browning and crispy edges

Helpful tips:

• Cold mashed potatoes work perfectly and are easier to handle, but room-temperature potatoes mix a bit more smoothly.

• Plain mashed potatoes are ideal, but seasoned ones work too—just adjust the added salt as needed.

How to Make Leftover Mashed Potato Cheese Puffs

This process is simple, relaxed, and very beginner-friendly. Take your time and enjoy it.

1. Prep the oven and pan: Preheat your oven to 400°F (200°C) and lightly grease a mini muffin tin or baking sheet.

2. Mix the base: In a large bowl, combine the mashed potatoes, cheddar cheese, and Parmesan cheese until evenly mixed.

3. Add the eggs: Stir in the eggs until the mixture is smooth and well incorporated.

4. Finish the batter: Add the flour, chives, garlic powder, black pepper, and salt, mixing just until a thick batter forms.

5. Portion evenly: Scoop tablespoon-sized portions into the pan for even baking.

6. Bake to perfection: Lightly spray the tops and bake until puffed, golden, and crisp around the edges.

Perfect Pairings

Dips & Sauces
These cheesy puffs are wonderful on their own, but a good dip takes them to the next level:

• Sour cream – Cool and creamy, it balances the rich, cheesy flavor perfectly

• Garlic aioli – Adds a savory, slightly indulgent touch

• Ranch dressing – A kid-friendly favorite that never disappoints

• Spicy ketchup – Just enough heat to contrast the crispy edges

Main & Side Pairings

Variations and Substitutions

One of the best things about this recipe is how flexible it is. A few small changes can completely transform the flavor.

Bacon & Cheddar Cheese Puffs

For an extra savory twist, stir in finely chopped, crispy bacon bits. The smoky bacon pairs beautifully with sharp cheddar, adding richness and depth to every bite. This version is especially popular for brunch spreads or game-day snacks, and it disappears fast—so you might want to make a double batch.

Gluten-Free Mashed Potato Cheese Puffs

It’s easy to make these puffs gluten-free. Simply swap the all-purpose flour for a gluten-free all-purpose blend or almond flour. Both options work well to hold the mixture together while keeping the inside tender. Just be sure your mashed potatoes are gluten-free as well.

Herb-Loaded Potato Cheese Puffs

Fresh or dried herbs add a lovely, aromatic touch. Parsley brings brightness, thyme adds warmth, and rosemary offers a cozy, savory note. Mix and match based on what you have on hand for a simple but flavorful upgrade.

Spicy Jalapeño Cheese Puffs

If you love a little heat, fold in finely diced jalapeños and swap cheddar for pepper jack cheese. The result is a gently spicy puff with bold flavor that’s perfect for parties.

Storage Instructions

Room Temperature Storage

These puffs are best enjoyed warm, but they can sit at room temperature for a short time when serving. They’re perfect for parties where guests can grab and go.

Refrigeration Tips

Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the oven or air fryer to bring back that crisp exterior.

Freezing & Make-Ahead Instructions

Mashed Potato Cheese Puffs freeze beautifully. Let them cool completely, then freeze in a single layer before transferring to a freezer-safe bag. Reheat straight from frozen in the oven until warmed through and crisp.

Recipe Tips and Tricks

Making Leftover Mashed Potato Cheese Puffs is wonderfully simple, but a few helpful tips can take them from good to truly irresistible. Think of these as friendly kitchen notes from someone who’s made them more than once—and learned a thing or two along the way.

• Avoid overly wet mashed potatoes
  If your mashed potatoes are very loose or creamy, the batter can become too soft. Thicker mashed potatoes help the puffs hold their shape and bake up light and fluffy.

• Don’t overmix the batter
  Gently stir just until everything is combined. Overmixing can make the puffs dense instead of airy, so a light hand goes a long way.

• Use mini muffin tins for uniform size
  Mini muffin tins make portioning easy and ensure even baking. Each puff comes out perfectly shaped and evenly golden.

• Spray tops lightly for extra crispness
  A quick spritz of cooking spray helps the tops brown beautifully and adds that crave-worthy crunch.

• Let cool slightly before serving
  A short rest allows the puffs to set, making them easier to handle and even more delicious.

If you’re new to baking, don’t worry—this recipe is forgiving, flexible, and designed for success.
