Ingredients You’ll Need

What’s fantastic about this recipe is how simple and approachable the ingredients are, yet they come together to create a dish rich in flavor and texture. Each item plays a crucial role, whether adding cheesy depth, a touch of freshness, or that perfect crispy crust.

2 cups leftover mashed potatoes: The creamy base that makes these puffs wonderfully moist and tender inside.
1 cup shredded cheddar cheese: Provides rich, melty cheesiness and a slight tang that elevates the flavor.
1/4 cup grated Parmesan cheese: Adds a salty, nutty punch, balancing the cheddar perfectly.
2 green onions, finely chopped: Bring fresh, mild sharpness that brightens every bite.
1/4 cup all-purpose flour: Works as the binder to hold everything together without weighing it down.
1 large egg, beaten: Ensures a sturdy mixture that crisps up nicely when baked.
1/4 teaspoon garlic powder: Infuses a subtle warmth and depth of flavor.
Salt and pepper to taste: Essential seasoning to bring out all the delicious layers.
Bread crumbs for coating (optional): Gives an extra crunchy exterior for those who crave a little more texture.
Olive oil or cooking spray for greasing: Helps achieve that golden, crispy finish on the baking sheet.

How to Make Leftover Mashed Potato Cheese Puffs Recipe

Step 1: Preheat and Prepare

Start by heating your oven to 400°F (200°C). Greasing your baking sheet with olive oil or cooking spray ensures the puffs won’t stick and get that perfect golden crust. Taking this step seriously means you’ll have beautifully crisp puffs every time.

Step 2: Mix All Ingredients

Gather your leftover mashed potatoes, cheddar cheese, Parmesan, green onions, flour, beaten egg, garlic powder, salt, and pepper in a large bowl. Mix everything thoroughly until you have a smooth, consistent mixture. Don’t worry if it feels a bit sticky—that’s exactly what you want to easily form perfect puffs later on.

Step 3: Shape the Puffs

Using your hands or a small ice cream scoop, form the mixture into small balls or patties and place them with enough space on your greased baking sheet. This part is fun because you can decide their size depending on whether you want snack-sized bites or more filling sides.

Step 4: Optional Bread Crumb Coating

If you’re craving extra crunch, gently roll each puff in bread crumbs before placing it on the baking sheet. This little touch adds a lovely crispy shell that contrasts beautifully with the soft filling underneath.

Step 5: Bake Until Golden

Pop the baking sheet in the oven and bake for 20 to 25 minutes. When they turn a lovely golden brown and feel crispy on the outside, you’ll know they’re ready. This baking time locks in the flavors and ensures the cheese melts perfectly inside the puffs.

Step 6: Cool Slightly Before Serving

Once out of the oven, let the puffs cool for a few minutes. This brief pause helps the center settle just right so they’re not too hot but still creamy and delicious when you bite in.

Step 7: Serve Warm and Enjoy!

These leftover mashed potato cheese puffs are best enjoyed fresh and warm, whether as a delicious snack, appetizer, or a charming side dish that will impress everyone at your table.

Garnishes

Sprinkling a little extra chopped green onion or some freshly grated Parmesan cheese over the top adds a burst of color and flavor that makes these puffs look as amazing as they taste. A tiny drizzle of sour cream or a dollop of your favorite salsa can also bring brightness and an extra layer of creaminess.

Side Dishes

These cheese puffs pair wonderfully with fresh green salads, roasted vegetables, or even a tangy tomato soup. Their rich, cheesy flavor contrasts beautifully with lighter or more acidic sides, creating a well-rounded plate that satisfies every craving.

Creative Ways to Present

Try arranging the puffs on a wooden board with small bowls of dipping sauces like ranch, spicy ketchup, or garlic aioli. For parties or casual gatherings, presenting them on skewers or tucked inside small lettuce cups makes for a fun and elegant snack everyone will adore.

Make Ahead and Storage

Storing Leftovers

If you have any leftover mashed potato cheese puffs, store them in an airtight container in the refrigerator for up to 3 days. Keeping them sealed preserves their freshness and flavor while preventing them from drying out.

Freezing

These puffs freeze beautifully! Arrange them on a baking sheet in a single layer and freeze until solid. Then transfer to a freezer-safe container or bag. They can be stored for up to 2 months, making them a convenient snack to have on hand whenever cravings strike.

Reheating

To bring your leftover puffs back to life, bake them in a preheated 375°F (190°C) oven for about 10 minutes, or until warmed through and crisp again. Avoid microwaving if you want to maintain their crispy exterior—the oven is key to that perfect texture.

FAQs

Can I use fresh mashed potatoes instead of leftover ones?

Absolutely! Fresh mashed potatoes work well, but slightly cooled and thick mashed potatoes hold together better, making shaping easier.

What if I don’t have green onions? Can I substitute them?

Yes! You can use finely chopped chives, shallots, or even a small amount of finely diced white onion for a similar mild onion flavor.

Is it necessary to add flour and egg?

Yes, the flour and egg help bind the mixture together so the puffs keep their shape during baking and develop a nice texture.

Can I make these puffs gluten-free?

Definitely! Substitute all-purpose flour with a gluten-free flour blend, and if coating with bread crumbs, use gluten-free crumbs instead.

What’s the best cheese to use for flavor?

Cheddar and Parmesan create a fantastic combo, but feel free to experiment with mozzarella for stretchiness or a sharp Asiago for an extra punch.
