Ingredients You’ll Need
For the Puffs:
- 2 cups cold mashed potatoes (leftover or freshly made)
- 1 large egg
- ¾ cup shredded cheddar cheese (or your favorite cheese blend)
- ¼ cup grated Parmesan cheese
- 2 tbsp chopped green onions or chives
- ¼ tsp garlic powder
- ¼ tsp black pepper
- Salt to taste (if mashed potatoes aren’t already seasoned)
- 2–3 tbsp all-purpose flour (as needed for texture)
Optional Topping:

Tools You’ll Need
- Mixing bowl
- Muffin tin or mini muffin tin
- Nonstick spray or butter for greasing
- Spoon or small scoop
- Grater and chopping board
Step-by-Step Instructions
Step 1: Preheat the Oven
Preheat your oven to 400°F (200°C). Lightly grease a muffin tin or mini muffin tin with nonstick spray or butter.
Step 2: Mix the Ingredients
In a mixing bowl, combine mashed potatoes, egg, shredded cheddar, Parmesan, green onions, garlic powder, and black pepper.
If the mixture feels too soft or wet, stir in a tablespoon of flour at a time until the mixture holds its shape when scooped.
Step 3: Fill the Muffin Tin
Spoon or scoop the potato mixture into each muffin cup, filling almost to the top.
For extra flavor, sprinkle a little extra cheese or herbs on top of each puff.
Step 4: Bake Until Golden
Bake for 20–25 minutes (15–18 minutes for mini muffin tin), or until the tops are golden brown and the edges are crispy.
Let cool for 5 minutes before carefully removing from the tin.
Step 5: Serve Warm
Serve warm on their own or with dipping sauces like ranch, sour cream, or a spicy aioli.
Tips for Perfect Mashed Potato Cheese Puffs
Use Cold Potatoes – They hold their shape better when mixing.
Avoid Overmixing – Stir just until combined for the fluffiest texture.
Customize – Add crumbled beef bacon, chopped jalapeños, or sautéed onions for fun twists.
Mini Muffins = Party Bites – Perfect size for serving a crowd or snacking.
Make Ahead – Prepare the mixture a day ahead and bake fresh before serving.
