The Backstory: How These Puffs Came to Be
The idea for these cheese puffs came from a post-holiday kitchen moment. After Thanksgiving, there was a mountain of mashed potatoes in the fridge. Reheating them felt boring, so I decided to experiment—adding cheese, breadcrumbs, and a little seasoning. A quick fry later, and boom—golden bites of heaven were born.
Since then, I’ve made them for birthday parties, weekend movie nights, and even as a last-minute appetizer when guests drop by. They always disappear fast.
Ingredients You’ll Need
These are pantry-friendly and highly flexible, so you might already have them on hand.
| Ingredient | Amount | Notes |
|---|---|---|
| Leftover mashed potatoes | 2 cups (cooled) | Use firm, not overly creamy mash for best shaping |
| Cheese | ½ cup grated | Cheddar, mozzarella, gouda, or a mix |
| Breadcrumbs | ¼ cup + extra for coating | Panko for extra crunch |
| Egg | 1 large, beaten | Acts as a binder |
| Fresh herbs (optional) | 2 tbsp chopped | Parsley, chives, thyme |
| Garlic powder (optional) | 1 tsp | Adds savory depth |
| Paprika (optional) | ¼ tsp | For color & mild heat |
| Salt & pepper | To taste | Adjust based on potato seasoning |
| Olive oil or vegetable oil | 2 tbsp | For frying (or spray for baking) |
Ingredient Tips
- Mashed potatoes: The firmer they are, the better they’ll hold shape. If yours are too soft, add extra breadcrumbs.
- Cheese: Use a cheese that melts well; sharp cheddar adds flavor punch, mozzarella gives stringy texture.
- Breadcrumbs: Panko gives a crunchier finish, but regular works too.
- Seasoning: Feel free to add onion powder, chili flakes, or even curry powder for a twist.
Step-by-Step Instructions
1. Prepare the Mixture
- In a large bowl, combine mashed potatoes, cheese, breadcrumbs, beaten egg, and herbs.
- Season with garlic powder, paprika, salt, and pepper.
- Mix until the mixture is cohesive but still soft. If it feels too wet, sprinkle in more breadcrumbs.
2. Shape the Puffs
- Scoop about 1–2 tablespoons of the mixture.
- Roll into a ball or flatten slightly into a patty.
- Coat lightly in extra breadcrumbs for a crispy shell.
3. Cook Them
For frying:
- Heat olive oil in a skillet over medium heat.
- Cook puffs for 2–3 minutes per side until golden and crisp.
- Drain on paper towels.
For baking (healthier option):
- Preheat oven to 200°C / 400°F.
- Place puffs on a parchment-lined tray.
- Lightly spray with cooking oil.
- Bake for 20–25 minutes, flipping halfway, until crisp.
4. Serve
- Enjoy hot with dipping sauces such as sour cream, ketchup, ranch, or spicy mayo.
- Garnish with fresh herbs for a pretty finish.

Flavor Variations

Pro Tips for Success
- Chill the mixture before shaping – This makes the puffs hold their form better during cooking.
- Don’t overcrowd the pan – Too many puffs at once lowers oil temperature and prevents crispiness.
- Taste before seasoning – Leftover potatoes may already have salt.
- Double coat for crunch – Roll in egg, then breadcrumbs again for an extra crispy bite.
- Serve immediately – They lose crispiness if they sit too long.
Healthier Cooking Swaps
- Bake instead of fry – Cuts down on oil.
- Use sweet potatoes – Higher in fiber and vitamin A.
- Swap breadcrumbs – Use almond flour or crushed oats for gluten-free.
- Choose low-fat cheese – Reduces calories while keeping flavor.

Storage & Freezing
- Refrigerate: Store in an airtight container up to 2 days. Reheat in oven for crispness.
- Freeze (uncooked): Shape puffs, freeze on a tray, then store in a bag. Cook from frozen with extra time.
- Freeze (cooked): Let cool completely, freeze, and reheat in oven or air fryer.
