Mashed Potato Cheese Puffs turn cooked mashed potatoes into savory, two-bite snacks with crisp golden edges and soft, cheesy centers. Cheddar provides a rich melt, Parmesan adds salty depth, and fresh chives brighten the potato mixture.
These puffs bake in a mini muffin pan, so there is no frying or shaping by hand. They are a practical way to use leftover mashed potatoes, but the potatoes should be cold and fairly thick for the puffs to hold their shape.

Why You’ll Love This Recipe
- Chilled mashed potatoes create a firmer mixture that is easier to portion and less likely to spread.
- Eggs bind the potatoes and cheese while helping the centers puff slightly during baking.
- A small amount of flour absorbs excess moisture without making the puffs dense or bready.
- Cheddar melts into the potato mixture, while Parmesan encourages savory browning around the edges.
- A greased metal mini muffin pan creates more browned surface area than baking the mixture in one large dish.

- 24-cup metal mini muffin pan
- Large mixing bowl
- Whisk
- Rubber spatula or sturdy spoon
- 1-tablespoon cookie scoop or measuring spoon

Ingredients You’ll Need
For the Potato Puffs
- 1 tablespoon (15 ml) unsalted butter, softened, for greasing the pan
- 2 cups (480 g) cold prepared mashed potatoes
- 2 large eggs (about 100 g without shells), lightly beaten
- 1 cup (115 g) shredded sharp cheddar cheese, divided
- 1/2 cup (45 g) finely grated Parmesan cheese, divided
- 1/4 cup (30 g) all-purpose flour
- 2 tablespoons (6 g) finely chopped fresh chives
- 1/2 teaspoon (2 g) baking powder
- 1/2 teaspoon (3 g) fine sea salt
- 1/4 teaspoon (0.5 g) ground black pepper
- 1/4 teaspoon garlic powder
For Serving
- 1/2 cup (120 g) sour cream, optional, for serving
- 1 tablespoon (3 g) finely chopped fresh chives, optional, for garnish
How to Make Mashed Potato Cheese Puffs with Cheddar and Parmesan
1. Preheat the oven
Position a rack in the center of the oven and preheat it to 400°F (205°C). Generously grease all 24 cups of a metal mini muffin pan with the softened butter, covering the bottoms and sides.
2. Check the mashed potatoes
Place the cold mashed potatoes in a large bowl. They should be thick enough to hold a mound on a spoon. If they are runny or spread quickly, stir in 1 additional tablespoon of flour before adding the remaining ingredients.
3. Combine the wet ingredients
Add the lightly beaten eggs to the mashed potatoes. Stir until the mixture is smooth and evenly combined, with no visible streaks of egg.
4. Add the cheese and seasonings
Reserve 1/4 cup (30 g) cheddar and 2 tablespoons (10 g) Parmesan for topping. Add the remaining cheddar and Parmesan to the potato mixture along with the flour, chives, baking powder, salt, black pepper, and garlic powder.
5. Mix the batter
Fold the ingredients together until evenly distributed. The mixture should be thick, scoopable, and slightly sticky. If it looks loose enough to pour, add another tablespoon of flour.
6. Fill the muffin pan
Divide the potato mixture evenly among the 24 prepared mini muffin cups, using about 1 heaping tablespoon per cup. The mixture can rise just above the rim. Smooth the tops lightly without compressing them.
7. Add the cheese topping
Sprinkle the reserved cheddar and Parmesan evenly over the puffs. Keep most of the cheese on the potato mixture rather than on the exposed pan, where it may burn.
8. Bake until golden
Bake for 22 to 26 minutes, rotating the pan after 15 minutes. The puffs are ready when the tops are golden, the edges are deeply browned, and the centers feel set rather than wet. An instant-read thermometer inserted into the center should register at least 160°F (71°C).
9. Rest in the pan
Let the puffs cool in the pan for 10 minutes. They will firm as they rest and release more cleanly than they would straight from the oven.
10. Release and serve
Run a thin butter knife or small offset spatula around the edge of each puff. Lift them carefully from the pan and serve warm with sour cream and additional chives, if using.
Tips for Success
- Use cold mashed potatoes. Warm potatoes create a softer mixture and may cause the puffs to spread or stick.
- Grease the pan thoroughly, including the upper edges of each cup where melted cheese can adhere.
- Finely grate the Parmesan so it disperses evenly instead of forming tough or overly salty pockets.
- Avoid packing the potato mixture firmly into the cups. A light scoop produces a softer center.
- Let the puffs rest before removing them. The hot interiors are delicate and may break if lifted too soon.
- If the tops are pale after 22 minutes, continue baking until the edges are clearly golden rather than relying on time alone.
Storage, Freezing, and Make-Ahead Instructions
Refrigerate cooled Mashed Potato Cheese Puffs in an airtight container for up to 4 days. Place parchment paper between layers to prevent sticking.
Reheat them on a baking sheet at 375°F (190°C) for 8 to 10 minutes, until hot and lightly crisp. For food safety, reheated puffs should reach 165°F (74°C). Microwave reheating is quicker but will soften the browned edges.
To freeze, cool the baked puffs completely and freeze them in a single layer on a tray. Transfer the firm puffs to a freezer-safe container and freeze for up to 2 months. Reheat from frozen at 375°F (190°C) for 15 to 18 minutes.
For make-ahead preparation, mix the potato batter and refrigerate it in a covered container for up to 24 hours. Stir it briefly before portioning. Add the cheese topping immediately before baking.
FAQ
Can I use instant mashed potatoes?
Yes, provided they are prepared thick and cooled completely. Instant mashed potatoes can be smoother and less flavorful, so taste the mixture before adding all the salt.
Why did my potato puffs stick to the pan?
The pan may not have been greased thoroughly, or the puffs may have been removed before they had time to set. Use a metal pan, coat each cup generously, and rest the baked puffs for 10 minutes before loosening them.
Can I make these in a standard muffin pan?
Yes. Fill 12 well-greased standard muffin cups about two-thirds full. Bake at 400°F (205°C) for approximately 25 to 30 minutes, checking that the centers are set and reach at least 160°F (71°C).
Why is my mixture too loose?
Mashed potatoes vary depending on how much milk, cream, or butter they contain. Add all-purpose flour 1 tablespoon at a time until the mixture is thick enough to hold its shape on a spoon.
Can I add cooked bacon or ham?
Yes. Fold in up to 1/2 cup of finely chopped cooked bacon or ham. Reduce the added salt because both ingredients contribute additional sodium.
