Ingredient Breakdown & Substitution Guide
Let’s take a closer look at what you’ll need and why:
1. Mashed Potatoes – 3 cups (cold)
Why cold? Cold mashed potatoes are firmer and easier to shape into puffs.
Fresh or leftover? Both work. If using leftovers, make sure they’re not overly wet or soupy.
No mash on hand? Boil and mash ~1.5 pounds of potatoes with a bit of butter and milk.
2. Egg – 1 large
Helps bind the mixture, giving the puffs structure.
If vegan: Try a flax egg (1 tbsp flaxseed + 3 tbsp water) or skip for a slightly looser puff.
3. Cheddar Cheese – 1 cup shredded
Use sharp or extra-sharp for a bold cheesy punch.
Substitutes: Mozzarella (for meltiness), Pepper Jack (for heat), or Gruyère.
4. All-Purpose Flour – 2 tablespoons
Adds just enough body to hold the mixture together without being doughy.
Gluten-free? Use a 1:1 GF blend or cornstarch.
5. Garlic Powder – 1 teaspoon
Infuses flavor throughout.
Fresh garlic can also be used: sauté 1 minced clove in a little butter before adding.
6. Salt & Pepper – To taste
Start with ½ tsp salt and ¼ tsp pepper, then adjust.
7. Fresh Chives – 2 tablespoons, chopped
Adds color, freshness, and mild onion flavor.
Swap with green onions or parsley if needed.
8. Grated Parmesan – For coating
Creates that savory, golden crust on the outside.
Use finely grated (not shredded) for best texture.
Instructions with Visual Cues & Tips
Let’s walk through this step-by-step for perfect results every time.
Step 1: Preheat and Prepare
Preheat your oven to 400°F (200°C).
Line a baking tray with parchment paper or lightly grease it. This prevents sticking and promotes even browning.
Pro Tip: If you have a silicone baking mat, it works perfectly here too.
Step 2: Mix the Base
In a large mixing bowl, combine:
3 cups cold mashed potatoes
1 egg
1 cup shredded cheddar cheese
2 tablespoons all-purpose flour
1 teaspoon garlic powder
2 tablespoons chopped chives
Salt and pepper to taste
Use a spatula or clean hands to mix until everything is thoroughly combined.
Troubleshooting Tip:
If the mixture feels too wet or sticky to roll, add 1–2 extra tablespoons of flour or chill the bowl for 15 minutes.
Step 3: Shape the Puffs
Use a small cookie scoop or spoon to portion about 2 tablespoons of mixture per puff.
Gently roll into a ball with your hands. Don’t pack it too tightly—this keeps the inside fluffy.
Makes around 18–20 puffs, depending on size.
Step 4: Coat in Parmesan
Pour grated Parmesan cheese onto a shallow plate.
Roll each puff gently to lightly coat the outside in Parmesan.
This gives a beautiful golden crust and adds an umami boost.
Step 5: Bake to Perfection
Arrange puffs 1 inch apart on your prepared tray.
Bake for 15–20 minutes, or until golden brown and puffed.
⏱️ Ovens vary—start checking at 15 minutes.
For extra crispiness, switch to broil for the last 2 minutes, but watch closely!
Step 6: Garnish and Serve
Sprinkle with extra fresh chives (or herbs of your choice).
Serve warm, straight from the oven.
Serving Suggestions
Party Platter: Serve with toothpicks and dip bowls of sour cream, hot sauce, or ranch.
Brunch Upgrade: Add crispy bacon bits and serve with poached eggs.
Lunch Side: Pair with a fresh green salad or soup.

⏱️ Make-Ahead & Freezer Tips
✅ Make Ahead (Fridge)
Shape and coat the puffs, place on a tray, cover tightly, and refrigerate up to 24 hours.
Bake directly from the fridge, adding 2–3 minutes to bake time.
❄️ Freeze (Unbaked or Baked)
Freeze unbaked puffs on a tray until solid, then transfer to a freezer bag.
To bake from frozen: Add 5–7 extra minutes in the oven.
To reheat baked puffs: Reheat at 350°F (175°C) for 8–10 minutes.
❓Frequently Asked Questions (FAQ)
Can I make these in an air fryer?
Yes! Air fry at 375°F (190°C) for 10–12 minutes, shaking once halfway. Great for small batches.
What if my mashed potatoes are too wet?
Add more flour, a tablespoon at a time, or chill the mixture before shaping.
Can I make these without egg?
Yes, though the puffs may be slightly softer. Add extra cheese or breadcrumbs to help bind.

Final Tips for Success
Don’t over-mix: Keep the mixture light to avoid dense puffs.
Use cold mashed potatoes for easier shaping.
Finely grate the Parmesan—shredded won’t stick well.
Avoid overcrowding the tray—space them out for browning.
