Ingredients

fries

1 liter water
1 teaspoon salt
1 cup instant polenta
2 tablespoon olive oil

for finishing

1 tablespoon olive oil
0.5 teaspoon paprika
0.5 teaspoon garlic powder

Method

Bring 1 liter of water and 1 teaspoon of salt to a boil in a large saucepan. As soon as it boils, pour in 1 cup of instant polenta in a thin stream, whisking with your other hand. This keeps lumps away.
Drop the heat to low. Keep whisking for 2–3 minutes until thick. When it looks like very thick mashed potatoes, stir in 2 tablespoons olive oil. Take the pot off the heat.
Line a baking sheet or rectangular pan with parchment paper. Scrape the hot polenta onto it and spread it out evenly to about 2 cm (¾ inch) thick. Use a spatula—a silicone one works best while it’s still warm.
Let the polenta cool at room temperature for about 20 minutes, until firm enough to cut. Preheat your oven to 220°C (425°F) during this time.
Flip the slab of cooled polenta onto a cutting board and slice into fries—around 1.5 cm (½ inch) wide is my sweet spot.
Brush each fry all over with olive oil (about 1 tablespoon total) and sprinkle with ½ teaspoon paprika and ½ teaspoon garlic powder. If your baking sheet has room, I lay them all out with a little space between.
Bake for 25–28 minutes, flipping halfway through, until the edges are crisp and golden. If they brown too fast, move them to a lower rack.
Let the fries sit for 2–3 minutes before moving—they’ll crisp up as they cool. Serve with your favorite dip or a squeeze of lemon. If you like extra crunch, give them a final 2-minute blast under the broiler.

Notes

I started making polenta fries because my air fryer can’t handle big batches, and oven-baking gets them all crisp without babysitting. The crispy outsides and creamy middles feel like a real treat—even though they’re simple pantry food.

Tricks for real crisp

Spread the polenta before it cools too much. Once it sets, shaping is tough and you’ll get jagged fries. I use a silicon spatula and really smooth the top—don’t stress if it’s not totally perfect; rustic works here.

When cutting, a basic chef’s knife works, but an oiled pizza cutter makes quick, clean strips (especially if doing double batches).

Don’t skip the step of brushing oil on every side. That thin coating is what makes the edges really crisp instead of chewy or dry.

Substitutions and variations

Fine cornmeal works, but it needs longer to cook—usually 25–30 minutes on the stove, and you’ll need extra water. If you have leftover grated parmesan or herbs like rosemary, sprinkle them on before baking for a savory kick. Sweet polenta (using a pinch of cinnamon and serving with yogurt) sounds fun, but baking it as fries never gave me good results. They fall apart or brown unevenly.

Make ahead and storing

Once the fries are baked and cooled, they keep in the fridge for 2–3 days. Reheat on a hot skillet or in the oven for crispiness. Don’t microwave—steam makes them limp. The unbaked polenta slab can be wrapped and chilled up to 2 days ahead, so you can slice and bake fresh if you’re hosting or packing lunches.
