Cheesy Mashed Potato Puffs

The Best Way to Reinvent Leftover Mashed Potatoes

I’ll be honest—leftover mashed potatoes used to sit in my refrigerator until I finally threw them away. No matter how much I loved mashed potatoes at dinner, reheated leftovers just never felt as exciting the next day.

That changed when I discovered Cheesy Mashed Potato Puffs.

One weekend, after a family gathering, I had a huge bowl of leftover mashed potatoes and didn’t want them to go to waste. I mixed in some cheese, eggs, and a few simple ingredients, then baked everything in a muffin tin. What came out of the oven was pure magic: fluffy potato centers surrounded by crispy golden edges and plenty of melted cheese.

Now, I actually look forward to having leftover mashed potatoes because these little puffs disappear almost as soon as they hit the table. They’re comforting, cheesy, easy to make, and perfect for everything from holiday leftovers to weeknight snacks.

If you’re looking for a creative potato recipe that the whole family will love, these Cheesy Mashed Potato Puffs are about to become your new favorite.

Ingredients

For the Potato Puffs

• 3 cups mashed potatoes (leftover or freshly made)
• 1 cup shredded cheddar cheese
• 1/4 cup grated Parmesan cheese
• 2 large eggs
• 1/4 cup milk
• 2 green onions, finely sliced
• 1/2 teaspoon garlic powder
• 1/2 teaspoon onion powder
• Salt and black pepper to taste

Optional Toppings

• Extra shredded cheddar cheese
• Chopped chives
• Crumbled bacon
• Sour cream for serving

Step-by-Step Method

Step 1: Preheat the Oven

Preheat your oven to 400°F (200°C).

Grease a standard 12-cup muffin tin generously with cooking spray or butter to prevent sticking.

Step 2: Prepare the Mixture

In a large mixing bowl, combine:

• Mashed potatoes
• Cheddar cheese
• Parmesan cheese
• Eggs
• Milk
• Green onions
• Garlic powder
• Onion powder
• Salt and pepper

Mix until everything is fully incorporated.

The mixture should be thick and creamy.

Step 3: Fill the Muffin Tin

Spoon the potato mixture evenly into the muffin cups.

Fill each cup nearly to the top.

If you love extra cheesy goodness like I do, sprinkle a little more cheddar cheese on top of each puff.

Step 4: Bake Until Golden

Bake for 20–25 minutes, or until:

• The tops are golden brown
• The edges become crispy
• The cheese is melted and bubbly

For extra crispiness, broil for the last 1–2 minutes while watching carefully.

Step 5: Cool Slightly and Remove

Allow the potato puffs to cool for about 5 minutes.

Run a butter knife around the edges if needed and carefully lift them from the muffin tin.

Serve warm for the best texture and flavor.

Cooking Tips for Perfect Potato Puffs

1. Use Cold Mashed Potatoes

I usually use chilled leftover mashed potatoes because they hold their shape better and create a sturdier puff.

2. Don’t Skip Greasing the Pan

Potatoes and cheese can stick easily. A well-greased muffin tin makes removal much easier.

3. Add More Flavor

Mix in:

• Crumbled bacon
• Diced ham
• Jalapeños
• Fresh herbs
• Cooked spinach

to create your own variation.

4. Use Sharp Cheddar

Sharp cheddar provides a richer cheese flavor and creates a more satisfying bite.

5. Watch the Broiler Carefully

The tops can go from perfectly golden to overly browned very quickly.

Frequently Asked Questions

1. Can I use instant mashed potatoes?

Yes. While homemade mashed potatoes offer the best flavor and texture, prepared instant mashed potatoes work well too.

2. Can I make these ahead of time?

Absolutely. You can prepare the mixture up to a day ahead and refrigerate it until ready to bake.

3. What cheese works best?

Cheddar is my favorite, but mozzarella, Monterey Jack, Gruyère, and Colby Jack all taste wonderful in this recipe.

4. Can I make them gluten-free?

Yes. This recipe is naturally gluten-free as long as all packaged ingredients are certified gluten-free.

5. Why are my potato puffs falling apart?

Usually, this happens if there isn’t enough egg in the mixture or if the puffs haven’t cooled slightly before being removed from the pan.
