Why You’ll Love This Recipe
I like this recipe because it is quick, budget-friendly, and incredibly satisfying. It helps me use up leftover mashed potatoes instead of letting them go to waste. The combination of cheddar and mozzarella gives the puffs a rich, melty texture that I find hard to resist. I also appreciate how simple the ingredients and steps are, making this recipe easy to prepare anytime.
Ingredients
(Tip: You’ll find the full list of Ingredients and measurements in the recipe card below.)
2 cups leftover mashed potatoes (cold or room temperature)
1 cup shredded cheddar cheese (sharp or medium)
1/2 cup shredded mozzarella cheese
1 large egg
2 tablespoons all-purpose flour
1/4 teaspoon garlic powder
1/4 teaspoon onion powder
Salt to taste
Black pepper to taste
Cooking oil for frying or nonstick spray for baking
Directions
I place the mashed potatoes in a large bowl and stir them until smooth. I add the cheddar cheese, mozzarella cheese, egg, flour, garlic powder, onion powder, salt, and pepper. I mix everything together until the mixture is fully combined and thick enough to scoop.
For frying, I heat oil in a skillet over medium heat. I scoop small portions of the mixture and carefully place them into the hot oil. I cook them for about 2 to 3 minutes per side, until they are golden brown and crisp. I remove them from the oil and let them drain on paper towels.
For baking, I preheat the oven to 400°F (200°C). I shape the mixture into small balls, place them on a lightly greased baking sheet, and bake for 18 to 22 minutes, turning once halfway through, until golden.
Servings And Timing
I usually get about 4 servings from this recipe.
Preparation time is around 10 minutes.
Cooking time is about 10 minutes when frying or 20 minutes when baking.
Total time is approximately 20 to 30 minutes.
Variations
I sometimes add chopped green onions or fresh herbs like parsley or chives for extra flavor. When I want a little heat, I mix in a pinch of paprika or cayenne pepper. I also enjoy swapping the cheeses for what I have available, such as using all cheddar or adding a small amount of parmesan.
Storage/Reheating
I store any leftover puffs in an airtight container in the refrigerator for up to 3 days. To reheat, I prefer using the oven or air fryer so they stay crispy. I warm them at 375°F (190°C) for about 5 to 7 minutes. I avoid reheating them in the microwave because they tend to become soft.
FAQs
Can I prepare the mixture ahead of time?
I often prepare the mixture a few hours in advance and keep it covered in the refrigerator until I am ready to cook.
Can these cheese puffs be frozen?
I find they freeze best after cooking. I let them cool completely, then freeze them in a single layer before transferring them to a freezer-safe container for up to 2 months.
Do the mashed potatoes need to be plain?
I prefer plain mashed potatoes, but lightly seasoned ones also work as long as I adjust the salt accordingly.
What can I serve with these puffs?
I like serving them with sour cream, ranch dressing, or a simple dipping sauce made with yogurt and herbs.
Can I make these without frying?
I often bake them instead of frying, and they still turn out delicious with a slightly lighter texture.
Conclusion
I love how these leftover mashed potato cheese puffs turn simple ingredients into something comforting and delicious. They are easy to make, customizable, and perfect for using up leftovers in a smart and tasty way. This recipe is one I come back to whenever I want something warm, cheesy, and satisfying without much effort.
