Ingredients

2 cups leftover mashed potatoes (cold or room temperature)
1 cup shredded cheddar cheese (sharp or medium)
½ cup shredded mozzarella cheese
1 large egg (for binding)
¼ cup all-purpose flour (or breadcrumbs)
½ teaspoon garlic powder (optional)
½ teaspoon onion powder (optional)
Salt and black pepper, to taste
Fresh parsley or green onions, finely chopped (optional)
Oil or butter, for greasing the pan

Step-by-Step Instructions

Step 1: Preheat the Oven

Preheat your oven to 400°F (200°C).
Lightly grease a muffin tin or line it with silicone or paper liners. This helps the puffs release easily and develop crispy edges.

Step 2: Combine the Potatoes and Cheese

In a large mixing bowl, add:

Mashed potatoes
Cheddar cheese
Mozzarella cheese

Mix until the cheeses are evenly distributed throughout the potatoes.

Step 3: Add the Binding Ingredients

Add the egg, flour, and optional seasonings (garlic powder, onion powder, salt, and pepper).

Mix until the mixture is thick and holds together when scooped.
If the mixture feels too soft, add flour one tablespoon at a time until it firms up.

Step 4: Shape the Puffs

Spoon the mixture into the prepared muffin tin, filling each cup about ¾ full.
Lightly press the tops down with the back of a spoon to help them bake evenly.

Step 5: Bake Until Golden

Place the tray in the oven and bake for 20–25 minutes, or until:

The tops are golden brown
The edges are crispy
The cheese is fully melted

For extra crispiness, switch to broil for the last 2–3 minutes.

Step 6: Cool Slightly and Serve

Remove from the oven and allow the puffs to cool for 5 minutes before removing them from the pan.

Serve warm for the best flavor and texture.

Texture and Taste

Crispy, lightly crunchy outside
Soft, fluffy potato interior
Rich cheddar flavor with gooey mozzarella pull

Each bite is comforting, cheesy, and satisfying.

Serving Suggestions

These mashed potato cheese puffs are delicious on their own, but even better with dipping sauces such as:

Sour cream
Garlic aioli
Ranch dressing
Spicy mayo or ketchup

They also pair well with roasted chicken, grilled meats, or a fresh salad.

Variations and Add-Ins

Bacon & Cheese Puffs: Add cooked, chopped bacon
Herb Puffs: Mix in chives, parsley, or thyme

Storage and Reheating

Store leftovers in an airtight container in the refrigerator for 3–4 days
Reheat in the oven or air fryer to maintain crispiness
Avoid microwaving if you want a crunchy texture
Freeze baked puffs for up to 2 months
