Ingredients for this recipe
- 2 cups leftover mashed potatoes
- 1 cup shredded cheddar cheese (or cheese of your choice)
- 1/4 cup grated Parmesan cheese
- 1 egg
- 2 tablespoons chopped fresh chives or parsley
- 1/4 teaspoon garlic powder
- Salt and pepper, to taste
- Nonstick cooking spray or melted butter (for greasing the muffin pan)

Step 1: Prep Your Oven and Pan
Preheat your oven to 400°F (200°C). Lightly grease a mini muffin tin with nonstick spray or brush with melted butter to prevent sticking and promote golden edges.
Step 2: Mix the Ingredients
In a large mixing bowl, combine the mashed potatoes, cheddar cheese, Parmesan cheese, egg, herbs, garlic powder, salt, and pepper. Mix well until everything is thoroughly incorporated. The mixture should be stiff enough to hold its shape when scooped.
Step 3: Fill the Muffin Tins
Using a spoon or small scoop, fill each muffin cup with the mixture. Gently press down to pack the filling in snugly, and smooth the tops.
Step 4: Bake to Perfection
Bake in the preheated oven for 20-25 minutes, or until the tops are golden brown and crisp. Allow them to cool in the pan for about 5 minutes before carefully removing with a spoon.
Step 5: Serve and Enjoy
Serve warm as a side dish, finger food, or snack. Add a dollop of sour cream or a sprinkle of herbs for extra flair.
Frequently Asked Questions
How do I keep the puffs from sticking?
Grease your muffin tin well with nonstick spray or melted butter. Also, let them cool slightly before removing.
Can I use instant mashed potatoes?
Yes, but be sure they are thick and not too runny, or the puffs won’t hold their shape.
What other cheeses can I use?
Mozzarella, pepper jack, Swiss, or a sharp cheddar all work well. Mixing cheeses adds flavor depth too.
Can I add meat or veggies?
Absolutely! Crumbled bacon, diced ham, or cooked spinach can be folded into the mixture for added flavor.
Can I make these ahead?
Yes! Make and refrigerate the mixture a day ahead, or freeze the baked puffs and reheat when needed.
Do I have to use a mini muffin pan?
It’s recommended for the best puff and crisp factor, but you can shape them by hand and bake on a parchment-lined tray too.
