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.

Ingredients

→ Main Ingredients

06 ½ teaspoon salt (adjust if your potatoes are pre-seasoned)
07 1 cup sharp cheddar cheese, shredded
08 ¼ cup plain flour
09 3 green onions, finely chopped
10 1 teaspoon baking powder

Instructions

Step 01

Heat up your oven to 375°F (190°C). Make sure the mashed potatoes are room temperature before you start working with them.

Step 02

Mix the mashed potatoes and milk together in a large bowl until smooth. Beat the eggs into the mixture one at a time.

Step 03

Add in the sour cream, melted butter, and salt. Stir gently until the mix is consistent.

Step 04

Use melted butter to coat a 12-hole muffin tin generously so nothing sticks.

Step 05

Gently fold the cheddar cheese and green onions into your potato mixture, making sure it’s mixed nicely.

Step 06

Lightly sprinkle the flour and baking powder over the mixture. Stir softly until combined, but don’t stir too much.

Step 07

Use a ¼-cup scoop to transfer the potato mix into each slot of the greased muffin tin, filling each one about three-quarters full.

Step 08

Put the tin into your heated oven and bake for 25–30 minutes, or until the tops are crispy and golden.

Step 09

Let the muffins rest in the tin for five minutes before taking them out. Enjoy while warm, perfect as a tasty side!

Notes

  1. These muffins puff up like regular ones but may sink slightly as they cool due to the potato-heavy batter. Totally normal!
  2. Depending on your mashed potatoes, the muffins can be a bit chunky or super soft. Instant makes them fluffier, while fresh keeps a bit of texture.
  3. Boost the flavors by adding crispy bacon bits into the batter or sprinkle on top.
