Ingredients

fries

1 cup instant polenta
3 cup water
0.5 teaspoon salt
1 tablespoon olive oil
3 tablespoon grated parmesan cheese
0.25 teaspoon black pepper
1 tablespoon cornstarch

for baking

2 tablespoon olive oil

Method

Line a medium baking dish (about 20x20 cm) with parchment, leaving overhang for easy lifting later.
Bring 3 cups water and 1/2 teaspoon salt to a boil in a medium saucepan. Once boiling, lower the heat.
Whisk in 1 cup instant polenta in a slow, steady stream. Keep whisking so it doesn’t clump. The polenta will thicken fast.
Stir for 2–3 minutes until the mixture pulls away from the sides. Take off the heat and mix in 1 tablespoon olive oil, 3 tablespoons parmesan, 1/4 teaspoon pepper, and 1 tablespoon cornstarch. Stir until smooth.
Scrape the hot polenta into the lined dish. Press it flat with a spatula or piece of parchment on top. It should be about 2 cm thick. Cool at room temp 15–20 minutes until firmed up.
Preheat your oven to 220°C (428°F). Lift out the firm polenta, use a sharp knife to cut it into fries about 1 cm thick.
Arrange fries on a parchment-lined baking sheet. Brush each with a little olive oil on all sides.
Bake 20–25 minutes, flipping once halfway, until crisp and browned at the edges. I always eat one hot off the tray to check they’re really crisp.
Let cool 2 minutes, then serve with your favorite dip or just as they are. If any stick, slide a metal spatula under while they’re still warm.

Notes

Polenta fries are my way of getting that crispy snack energy without needing a deep fryer or planning ahead. It’s also how I use the half-bag of quick-cook polenta I always seem to have lurking in my pantry.

Tips from my own kitchen

Spread polenta hot—not warm—into the dish. If you let it cool before spreading, it turns chunky and won’t pack tightly, so the fries break or crumble later. Learned that the sticky way more than once.

Don’t skip the cornstarch. It’s a little hack I use for extra crispness at the edges—otherwise, they can taste more like soft roasted polenta. If you want even more crunch, brush the fries with olive oil twice: once before the oven, once halfway through.

I cut mine a bit thicker than classic French fries so they hold up better for dipping and don’t dry out.

Substitutions & variations that actually work

If you’re out of parmesan, try pecorino or skip the cheese—just bump up the salt a notch. I don’t recommend skipping the olive oil; they just don’t crisp up the same with cooking spray or no oil at all.

For a totally dairy-free take, skip the cheese and add extra black pepper and a pinch of smoked paprika.

Storage & prep ahead

Once baked, these reheat surprisingly well. I let leftovers cool, store in a glass container in the fridge, and bake at 200°C (400°F) for about 7 minutes to bring them back. They’re best the day they’re made but still beat standard leftover fries.
