- 1/4 cup chopped parsley or green onions
- 1 teaspoon garlic powder
- 1/2 teaspoon onion powder
- 1/2 teaspoon salt (adjust to taste)
- 1/2 teaspoon black pepper
- 2 tablespoons cornstarch (helps with structure and crispiness)
- 1 egg (optional, helps bind)
For coating (optional but extra crispy)

How to Make Crispy Potato Squares (Step-by-Step)
1) Cook the potatoes
Peel and cut potatoes into chunks. Boil in salted water until fork-tender, about 12–15 minutes. Drain well and let them sit for 2 minutes so steam escapes. Less moisture means crispier results.
2) Mash and season
Mash potatoes until smooth. Add butter, garlic powder, onion powder, salt, pepper, chopped herbs, and cheese if using. Mix well. Sprinkle in cornstarch and stir again. If you want extra binding, add one egg while the potatoes are warm (not hot) and mix quickly.
3) Shape into a slab
Line a tray or baking dish with parchment paper. Spread the potato mixture into an even layer (about 1/2-inch thick). Smooth the top with a spoon or spatula.
4) Chill until firm
Refrigerate for at least 1–2 hours until firm. This step is key—firm potatoes cut cleanly and fry better without breaking.
5) Cut into squares
Lift the slab out using parchment, then cut into bite-size squares. You can do small snack squares or larger pieces for a side dish.
6) Coat (optional)
For ultra crispy squares, coat each piece:
- Light dusting of flour
- Dip in beaten egg
- Coat in breadcrumbs or panko
If you want a simpler version, you can skip the coating and go straight to frying or baking.
7) Cook until golden
Frying: Heat oil to 350°F (175°C). Fry squares in batches 2–3 minutes per side until deep golden brown.
Baking: Bake at 425°F (220°C) for 20–25 minutes, flipping halfway. Brush or spray with oil for crispiness.
Air fryer: Air fry at 400°F (200°C) for 10–14 minutes, shaking halfway.
Tips for Perfect Potato Squares
- Drain potatoes well to avoid a wet mixture.
- Chill the slab so it cuts cleanly and holds shape.
- Cornstarch helps create structure and a crisp bite.
- Don’t overcrowd the pan when frying—crowding lowers oil temperature.
- Use panko if you want the crispiest coating.

Storage and Reheating
Fridge: Store cooked squares in an airtight container up to 3 days.

Freeze: Freeze uncooked squares on a tray, then transfer to a bag. Cook from frozen by adding a few extra minutes.
Frequently Asked Questions
Can I use leftover mashed potatoes?
Yes—this is a great way to use leftovers. If they’re very soft, add extra cornstarch to help firm them up.
Why did my squares fall apart?
Usually from too much moisture or not chilling long enough. Drain potatoes well and chill until fully firm.
Can I make them without cheese?
Absolutely. They’ll still be flavorful with herbs and seasoning.
