How to Make Leftover Mashed Potato Cups

To make these bite-size, I use a mini muffin pan, it makes up to 24 at once. You could also use a regular muffin tin and just fill each cup halfway, but they will be slightly larger.

Watch how this recipe comes together in the video below, and then check out the step-by-step below.

Prep
Preheat the oven to 400F and lightly grease a 24-count mini muffin pan.
Whisk the eggs
In a small bowl, whisk the eggs until smooth.
Make the “batter”
Combine the mashed potatoes, eggs, shredded Cheddar cheese, bacon, black pepper, and chives in a large bowl. Fold the ingredients until the eggs are completely incorporated.
Bake
Fill each muffin cup with the potato mixture and top each with the remaining cheese. Bake for 18 minutes until the tops achieve that golden brown crust.
Time to eat
Remove from the oven and allow to cool before serving with sour cream.

How to Freeze and Reheat Mashed Potato Cups

Once cooked and after being fully cooled, mashed potato cups can be frozen in an airtight zip bag for up to 2 months.

To reheat in the oven, preheat the oven to 350F, place the mashed potato cups on a parchment-lined baking sheet, and warm them for 12 to 15 minutes. They can also be microwaved for 30 seconds to 1 minute, depending on how many you warm up at once.

How to Serve Leftover Mashed Potato Cups

How you serve these cheesy baked potato cups is entirely up to you. I love the combination of baked potato and sour cream, so I usually serve some on the side for a dip, but these also make a good side option with entreés like:
