Ingredients

polenta fries

1 cup polenta or instant cornmeal
3 cup water
1 teaspoon salt
2 tablespoon olive oil
0.5 cup grated parmesan cheese

for baking

2 tablespoon olive oil

Method

Line a medium baking dish (about 20x20cm or 8x8in) with parchment paper. Brush lightly with a bit of olive oil so the fries won’t stick later.
Bring 3 cups of water to a boil in a pot. Once bubbling, add 1 teaspoon salt. Lower the heat to medium and sprinkle in the polenta gradually, stirring all the time with a whisk or wooden spoon. This helps avoid lumps (don’t rush it, it takes about 2-3 minutes).
Keep stirring until the mixture thickens to a soft but spreadable texture—this usually takes 5-8 minutes, depending on your polenta. Turn off the heat.
Stir in 2 tablespoons olive oil and 1/2 cup grated parmesan. Mix until smooth and glossy. Scoop the polenta into your lined pan and press it into an even, compact layer. Let it cool until completely firm—about 1 hour at room temp, or speed it up in the fridge (20–30 minutes).
When the polenta is solid, lift it from the pan using the paper. Slice into "fries" about 1cm (1/2 inch) thick. Don’t worry if the edges look a little rough—those turn crispest.
Preheat your oven to 220°C (425°F). Arrange fries on a lined baking sheet, leaving a little space between each for browning. Brush with the remaining olive oil.
Bake 20–25 minutes, flipping halfway, until both sides are crisp and deep golden. Let them cool 5 minutes before eating—they firm up as they sit.

Notes

I started making polenta fries after I got bored of oven potato wedges. Turns out, crisp polenta fries stay crunchy way longer, and you can cut them as thick or skinny as you want. My kid will eat them cold in a packed lunch—huge win.

How I get crisp edges (and avoid hassle)

The secret is cooling the polenta until it’s really firm before slicing. Warm polenta will always fall apart, no matter how carefully you handle it. I make the polenta the night before and let it set in the fridge—next day, it’s ready to slice, and cleanup is a breeze.

If the fries look a bit ragged when you cut them, don’t trim! The little craggy bits are where you get those crunchy edges that actually taste better than the smooth sides.

I also brush on olive oil right before baking instead of mixing in extra oil. This gives more of those blistered, toasted spots instead of a uniform soft fry.

Substitutions and tweaks

Instant polenta or regular works the same for fries. If you’re going dairy-free, swap parmesan for about 2 tablespoons nutritional yeast. Skip trying vegan cheese—it usually stays gummy here.

For a punchy twist, I sometimes stir in chopped rosemary or smoked paprika with the parmesan. Garlic powder works too—fresh garlic doesn’t spread evenly and can burn.

Storage and meal prep

These keep in a sealed container in the fridge up to 3 days. Reheat in a pan or air fryer for max crunch. I never freeze them—the texture goes gritty.
