Found this in my aunt’s recipe box from the 1960s. These disappeared in minutes at the church potluck.

This Oven-Baked Party Potato Puffs recipe is a masterclass in secondary thermal protein-starch coagulation and capsular steam expansion. By utilizing cold leftover mashed potatoes, you work with a matrix where the starches have already undergone retrogradation, locking them into a firm, workable structure. When blended with lightly beaten eggs and baked at 400°F, the egg proteins denature and cross-link, creating a highly stable structural net that traps the potato starches. Simultaneously, the moisture within the dairy and eggs vaporizes into steam, expanding the core into a light, pillowy puff while the surface cheddar cheese undergoes a rapid Maillard reaction, forming a crisp, golden outer protective crust.

Oven-Baked Party Potato Puffs

Ingredients:

Step-by-Step Directions:

Step 1: The Cold Starch De-Clump: Preheat your oven to 400°F and lightly grease a 24-count mini muffin pan with cooking spray or butter. In a medium mixing bowl, add the cold mashed potatoes and use a fork to break them up gently until no dense clumps remain.

Tip: Starting with cold, firm mashed potatoes is an absolute structural necessity. Leftover potatoes that have chilled overnight have undergone starch retrogradation, which means the amylose molecules have recrystallized into a rigid network. Warm or freshly made mashed potatoes will be too fluid and runny, causing the puffs to liquefy and collapse into flat discs in the oven.

Step 2: The Coagulation Fluid Bind: Pour the lightly beaten eggs into the bowl and stir vigorously until the potato starch absorbs the liquid phase completely, yielding a smooth, thick, and scoopable slurry.

Note: The mixture should hold its shape on a spoon without dripping, showing a completely uniform texture with no independent pools of liquid egg.

Step 3: The Particulate Integration: Add the shredded cheddar cheese and finely chopped green onion or chives to the potato dough, folding them in with a spatula until they are evenly distributed.

Tip: Take a moment to taste a tiny bit of the raw mixture at this stage. Because leftover mashed potatoes vary widely in their initial seasoning levels, you may need to toss in a quick pinch of salt and black pepper to balance out the extra volume introduced by the eggs.

Step 4: The Geometric Pan Loading: Using a small spoon or tablespoon measure, scoop the potato mixture into the greased mini muffin cups, filling each well almost to the top. Gently pat the tops flat, then leave a slight mound in the center of each cup.

Note: The cups should be uniformly full to ensure that hot air circulates across an even plane, allowing every puff to bake at an identical rate.

Step 5: The High-Heat Thermal Set & Rest: Bake on the middle oven rack for 18/22 minutes until the puffs are structurally set, the edges turn deep golden brown, and the tops form a crisp skin. Remove from the oven and let the puffs rest undisturbed inside the pan for exactly 5 / minutes before handling.

Tip: The 5-minute cooling window is an efficiency-driven viscosity milestone. Straight out of the hot oven, the melted cheddar lipids and egg proteins are highly fluid and fragile; allowing the temperature to drop slightly forces the protein lattice to contract and solidify, ensuring you can lift the puffs out cleanly without them breaking apart.

Step 6: The Perimeter Release: Run the blunt tip of a butter knife carefully around the perimeter of each well to break any cheese bridges, then gently lift the warm potato puffs out and transfer them to a serving platter.
