  • Cook Time: 20–25 minutes

  • Total Time: 45 minutes

  • Calories: ~90 kcal per puff

 Ingredients

Main Mixture:

  • 2 cups leftover mashed potatoes (cold or room temperature)

  • 1 cup shredded cheddar cheese (sharp or medium)

  • 1/2 cup mozzarella cheese, shredded

  • 1/4 cup Parmesan cheese, grated

  • 1/4 cup chopped green onions or chives

  • 1 large egg

  • 1/2 teaspoon garlic powder

  • 1/2 teaspoon onion powder

  • Salt and black pepper to taste

  • 1 tablespoon chopped fresh parsley (optional)

  • 2 tablespoons sour cream or Greek yogurt (for creaminess)

Breading (Optional for crispy coating):

  • 1 cup Panko breadcrumbs or regular breadcrumbs

  • 1/2 teaspoon paprika

  • 1/4 teaspoon dried oregano

  • 2 tablespoons grated Parmesan cheese

  • 1 beaten egg (for egg wash)

  • 1/2 cup flour (for dredging)

Optional Add-ins (customize to your liking):

  • Cooked crumbled bacon

  • Jalapeños or chili flakes (for a spicy twist)

  • Minced sautéed onions or caramelized shallots

  • Shredded cooked chicken

 Instructions

Step 1: Prepare the Mixture

In a large mixing bowl, combine:

  • Cold mashed potatoes

  • All three cheeses

  • Egg

  • Garlic and onion powder

  • Salt, pepper, and parsley

  • Sour cream or Greek yogurt

  • Chopped green onions or any additional mix-ins like bacon or jalapeño

Use a spatula or clean hands to gently combine the ingredients until you have a smooth, thick mixture that holds together when rolled.

Tip: If your mashed potatoes are too soft, add 1–2 tablespoons of flour or breadcrumbs to firm up the mixture.

Step 2: Shape the Puffs

Using a tablespoon or small cookie scoop, form the mixture into small balls (about 1 to 1.5 inches wide). You can make them slightly flattened discs for more surface area and crispiness.

Place them on a parchment-lined baking sheet. If using the breaded method, chill the shaped puffs in the fridge for 20 minutes to firm up.

Step 3: Coat (Optional but recommended for crispy texture)

Set up a breading station with three bowls:

  1. Flour

  2. Beaten egg

  3. Breadcrumb mixture (Panko + Parmesan + paprika + oregano)

Roll each puff first in flour, then dip in egg wash, then coat with breadcrumbs. Press gently to ensure the coating sticks well.

Step 4: Cook the Puffs

You can cook these cheese puffs using your preferred method:

 Air Fryer Method:

  • Preheat air fryer to 375°F (190°C)

  • Spray basket and puffs lightly with cooking spray

  • Cook in batches for 10–12 minutes, flipping halfway through

  • Look for golden brown and crisp outsides

 Oven Method:

  • Preheat oven to 400°F (200°C)

  • Place puffs on a lined baking tray and spray with oil

  • Bake for 20–25 minutes or until golden and crispy, flipping halfway

 Pan-Fried Method (for extra indulgence):

  • Heat a skillet with 1/4 inch of oil

  • Fry each puff until golden brown and crispy

  • Drain on paper towels

  • Party appetizers

 Tips and Tricks for Perfect Cheese Puffs

  1. Use Cold Mashed Potatoes:
    Fresh hot mashed potatoes are too soft. Let them cool and firm up before mixing.

  2. Mix Cheeses:
    Combining cheddar, mozzarella, and Parmesan gives the best flavor and texture. Cheddar melts into gooey richness, while Parmesan adds umami.

  3. Customize the Texture:
    Add more flour or breadcrumbs to firm them up, or a splash of milk if too stiff.

  4. Spice It Up:
    Crushed red pepper, smoked paprika, or Cajun seasoning can elevate the flavor.

  5. Crispier Finish:
    For extra crunch, double-coat with breadcrumbs or use crushed cornflakes or crushed Ritz crackers in the breading.

  6. Use Silicone Molds:
    For uniform shapes, use mini muffin pans or silicone molds and bake them like mini quiches.
