Crunchy exterior with a soft core, these potato muffin cups turn basic spuds into something special. They're great for using up yesterday's mashed potatoes from the fridge, or you can whip up a fresh batch just for this. Each cup gives you the ideal serving with a golden, cheese-covered outside that breaks open to reveal a soft, tasty center.
The first time I tried making these was during a family dinner when I had way too many leftover mashed potatoes. I was just going to warm them up, but then I got a better idea and these tasty muffins happened. Everyone crowded into the kitchen as soon as they came out of the oven and grabbed them faster than I could serve them.
Tasty Ingredients For Potato Muffins
- Mashed Potatoes: Can use leftovers, freshly made, or even instant. They work best when they're not hot anymore.
- Milk: Makes everything stick together and adds moisture. The fattier the milk, the tastier the result.
- Cheddar Cheese: Brings strong flavor and helps make that nice golden top.
- Sour Cream: Adds creaminess and a bit of tang to the mix.
- Green Onion: Gives a light onion kick and makes everything look prettier.
- Butter: Makes them richer and helps the outside get crispy.
- Salt: Pulls all the flavors together.
- Baking Powder: Helps the muffins puff up slightly.
- Flour: Gives them shape without making them heavy.
Crafting Delicious Potato Cups
- Blending Basics:
- Mix your cooled potatoes with milk, stirring lightly to keep their texture while making them moist.
- Adding Structure:
- Put in eggs one by one, mixing well each time to help the muffins hold together.
- Making It Rich:
- Stir in salt, melted butter, and sour cream until everything's well combined.
- Prepping Your Pan:
- Coat the muffin tin with lots of melted butter so they won't stick and will get crispy.
- Adding Flavor Boosts:
- Mix in green onions and cheese so they spread throughout the batter.
- Building Framework:
- Add flour and baking powder with light mixing – don't stir too much.
- Filling Properly:
- Use a ¼ cup scoop to fill each cup about ¾ of the way.
- Cooking Till Golden:
- Bake until the tops turn golden brown with crispy edges.

I really love how flexible potatoes can be. In my childhood, my grandma used to make what she called 'potato puffs,' which were kinda like these muffins but not as neat. The cheese makes a crunchy outside that reminds me of those childhood treats, but these muffins have grown-up flavors that I enjoy now.
Fantastic Food Companions
These potato cups go well with almost any meat. Try them with steak, baked chicken, or fish off the grill. For breakfast or brunch, top them with a runny egg and extra cheese for a filling meal to start your day.
Change It Up
Play around with these potato muffins by adding fresh herbs such as rosemary or thyme. Try different cheeses like gruyère, gouda, or pepper jack instead of cheddar. Want some spice? Throw in chopped jalapeños or a dash of cayenne. Add veggies like bell peppers, corn, or spinach for more color and nutrients.
Storage Tips
Keep leftover muffins in a sealed container in the fridge for up to three days. To save them longer, freeze them on a baking sheet until hard, then put them in freezer bags for up to two months. Heat frozen muffins in a 350°F oven for 25-30 minutes. Muffins from the fridge need 15-20 minutes to get crispy again.

I've been making these potato muffins for years now, and they've become one of my family's favorites. What started as just using up leftovers has turned into something everyone asks for. I still love watching people try them for the first time—that moment when they realize mashed potatoes can be so much more than just a blob on their plate. These muffins aren't fancy, but they show that simple ingredients can make something truly memorable.
