The Ingredients

This recipe uses simple, affordable ingredients that come together beautifully.

2 cups cold leftover mashed potatoes(firm, not runny) – The base of the puffs. Cold potatoes hold their shape better.
2 large eggs, lightly beaten – For binding and lift.
1 cup shredded cheddar cheese (mild or medium) – For gooey, cheesy flavor.
¼ cup finely chopped green onion or chives – For freshness and color.

Step-by-Step Instructions

Step 1: Preheat and Prep

Preheat your oven to 400°F (200°C). Lightly grease a mini muffin pan (24-count) with cooking spray, shortening, or a little butter.

Pro Tip: Grease well! The puffs will stick if you don’t.

Step 2: Prep the Potatoes

In a medium mixing bowl, add the completely cold mashed potatoes. Break them up gently with a fork so there are no big, hard clumps remaining.

Pro Tip: Cold mashed potatoes work best. Warm potatoes will be too soft and won’t hold their shape.

Step 3: Mix in the Eggs

Stir the lightly beaten eggs directly into the cold potatoes until the mixture looks completely smooth and the eggs are fully worked in.

Pro Tip: Make sure the eggs are fully incorporated before adding the other ingredients.

Step 4: Add the Mix-Ins

Add the shredded cheddar cheese and the finely chopped green onion or chives. Stir the batter until everything is evenly combined.

Pro Tip: Save a little cheese and green onion to sprinkle on top for a beautiful finish.

Step 5: Fill the Pan

Using a small spoon or a tablespoon measure, scoop the thick potato mixture directly into the prepared mini muffin cups, filling each one almost to the top. Gently press the tops down to smooth them out.

Pro Tip: Don’t overfill! The puffs will rise slightly as they bake.

Step 6: Bake to Golden Perfection

Bake on the middle rack for 18–22 minutes, or until the puffs are fully set, the edges are golden brown, and the tops look lightly crisp.

Pro Tip: Watch them closely toward the end. The edges can go from golden to burnt quickly.

Step 7: Rest and Serve

Remove the hot pan from the oven and let the potato puffs cool and set in the pan for exactly 5 minutes. Run the tip of a butter knife carefully around the edges if needed, then gently lift the puffs out of the tin and serve warm.

Pro Tip: The 5-minute rest is essential—it allows the puffs to set and makes them easier to remove.
