Step-by-Step Instructions
Step 1: Prepare the Oven and Pan
First, preheat your oven and lightly grease a standard muffin tin or line it with paper liners. This helps the puffs release easily after baking.
Step 2: Mix the Base Ingredients
Next, add the cooled mashed potatoes, eggs, shredded cheddar, Parmesan cheese, sour cream, and green onions to a large bowl. Stir until the mixture looks smooth and evenly combined.
Step 3: Add the Seasonings
Then, sprinkle in the garlic powder, salt, black pepper, and baking powder. Mix thoroughly so the baking powder is evenly distributed. This step helps keep the puffs light and airy.
Step 4: Fill the Muffin Cups
After that, divide the potato mixture evenly among the prepared muffin cups. Fill each one about three-quarters full so there’s room for the puffs to rise as they bake.
Step 5: Bake Until Golden
Place the muffin tin in the oven and bake until the tops turn golden brown and slightly crisp. The puffs should feel set and lightly firm to the touch.
Step 6: Cool and Serve
Finally, let the cheesy mashed potato puffs cool briefly in the pan before removing them. Serve warm for the best texture and flavor.

Tips for Best Results
- Use cooled potatoes: Warm mashed potatoes can affect the texture.
- Don’t overmix: Stir just until combined to keep the puffs fluffy.
- Customize the cheese: Sharp cheddar adds flavor, but other melting cheeses work well.
- Make them loaded: Add cooked bacon or ham for a heartier bite.
- Reheat for crispness: Use the oven or toaster oven instead of the microwave.
