Crunchy exterior with a soft center, these potato cup treats take ordinary spuds to a whole new level. They're great for using up yesterday's mashed potatoes in your fridge, or worth whipping up a new batch just for these. Each cup gives you the perfect serving with its golden, cheese-crusted outside that breaks open to reveal a soft, tasty middle.
I first threw these together during a family dinner when I had way too many leftover mashed potatoes. I was just going to warm them up again, but then I got a better idea and these tasty cups were the result. Everyone hung around the kitchen when they came out, grabbing them before I could even serve them properly.
Tasty Ingredients For Potato Muffins
- Mashed Potatoes: Can be leftovers, freshly smashed, or even the instant kind. They work best when they've cooled down before mixing.
- Milk: Makes everything moist and helps mix it all together. The fattier the milk, the better they'll turn out.
- Cheddar Cheese: Gives a strong taste and helps make that golden outside layer.
- Sour Cream: Adds a creamy richness and a bit of tang.
- Green Onion: Brings a light onion taste and nice green color.
- Butter: Makes everything richer and helps create that crispy outside.
- Salt: Pulls all the flavors together.
- Baking Powder: Helps the muffins puff up slightly.
- Flour: Gives them shape without making them too heavy.
Crafting Delicious Potato Cups
- Blending The Basics:
- Mix cool mashed potatoes with milk, stirring gently to keep their fluffiness while getting them wet enough.
- Adding What Holds It Together:
- Put eggs in one at a time, mixing them in completely for better structure.
- Making It Richer:
- Stir in salt, melted butter, and sour cream until everything's well mixed.
- Getting The Pan Ready:
- Coat the muffin tin with lots of melted butter so they won't stick and will get crispy.
- Mixing In Flavor Boosters:
- Add green onions and grated cheese, making sure they're spread throughout.
- Building The Framework:
- Lightly mix in flour and baking powder, but don't stir too much.
- Filling Each Cup:
- Use a ¼ cup scoop to fill each muffin spot about ¾ full.
- Cooking Them Golden:
- Bake until the tops look golden brown and the edges get crispy.

I really love how flexible potatoes can be. When I was little, my grandma would make what she called 'potato puffs,' which were kinda like these cups but not as well-shaped. The cheese makes a crunchy outside that reminds me of those childhood treats, but these cups have fancier flavors that I enjoy more now that I'm grown up.
Great Food Combinations
These potato cups go well with almost any meat. Try them with steak, baked chicken, or fish off the grill. For breakfast, stick a runny egg and some extra cheese on top for a filling morning meal.
Switch Things Up
Change these potato cups by adding fresh herbs like rosemary or thyme. Try different cheeses instead of cheddar, such as gruyère, gouda, or pepper jack. Want some kick? Throw in chopped jalapeños or a dash of cayenne. Add veggies like bell peppers, corn, or spinach for more nutrients and color.
Storing For Later
Keep cooled cups in a sealed container in your fridge for up to three days. To freeze them, put them on a baking sheet until hard, then move to freezer bags for up to two months. Heat frozen cups in a 350°F oven for 25-30 minutes. If they're just from the fridge, 15-20 minutes will get them crispy again.

After making these potato cups for years, they've become a family favorite at my house. What started as just using up leftovers has turned into something everyone asks for. I still love seeing someone try one for the first time—that moment when they realize mashed potatoes can be so much more than just a blob on their plate. These cups aren't fancy, but they show how basic ingredients can make something truly memorable.
