Through many batches, I've learned that the type of mashed potatoes you start with makes a big difference. Creamy, well-seasoned potatoes with plenty of butter create the best final texture.
Mastering the Perfect Puff
The secret lies in not compressing the mixture too much when filling the tins. I've found that a light touch helps them puff up beautifully while baking.
Temperature Control
Starting with room temperature ingredients helps everything mix evenly and bake consistently. I learned this after wondering why some batches weren't as puffy as others.
Cheese Selection
While Monterey Jack is our favorite, mixing cheeses can create incredible flavor combinations. A sharp cheddar and gruyere blend has become our holiday version.

These Cheesy Mashed Potato Puffs have become our favorite way to transform leftovers into something new and exciting. They prove that sometimes the best recipes come from creative solutions to using up what's left in the fridge!
