Cheesy Polenta Fries with Marinara and Melted Provolone Step-by-step instructions

Before you start

Start by chilling the polenta block so it is firm enough to slice cleanly. Set out a wooden cutting board, a sharp chef's knife, and a box grater. Chill the provolone for about 10 minutes so it grates without smearing, then grate half of it and slice the rest thin. Warm the marinara in a small saucepan until it is hot, which keeps the skillet from cooling down when you add it.

Line a plate with paper towels to drain the fries, and have tongs within reach. Pour the oil into the cast iron skillet and set it aside until you are ready to heat it. Having every element ready means the fries go from the oil to the cheese in one smooth, uninterrupted sequence, so they stay hot and crisp at the table.

Instructions

Slicing and grating

1. 1Slice the chilled polenta
   Set the firm polenta block on a wooden cutting board. Using a chef's knife, slice it into long rectangular sticks about 1/2 inch thick, roughly the shape of French fries. Season the sticks lightly on all sides with kosher salt.
   Look for Cut edges look clean and the sticks hold their shape without crumbling.
   Tip Keep the block cold while you cut so the sticks stay firm and do not break.
2. 2Grate the provolone
   Grate half of the provolone on the large holes of a box grater, letting the shreds fall onto the board. Slice the remaining provolone thin, ready to lay over the fries later.
   Look for A fine pile of shredded cheese sits on the board next to the thin slices.
   Tip Chill the provolone for 10 minutes first so it grates cleanly without smearing.

At the end of this phase, the polenta should be cut into even, long rectangular sticks that hold their shape without crumbling at the edges. Each piece should be lightly seasoned with salt on all sides, and the cut surfaces should look clean and slightly matte.

The provolone should be divided into a fine pile of shredded cheese and a stack of thin slices. Check that the sticks are roughly the same thickness so they fry at an even rate. If any pieces crack or crumble, chill them again for ten minutes before going on, because cold polenta is far easier to handle in hot oil and will keep its shape in the pan.

Frying to golden

3. 3Fry the polenta fries
   Pour the oil into the cast iron skillet until it is about 1/2 inch deep, and heat it over medium-high heat. Add the garlic cloves and chili peppers if you like. Fry the polenta sticks in batches until they are golden brown and crisp on the outside, turning them with tongs, then drain on paper towels.
   Look for Fries are deep golden and crackle when pressed gently with tongs.
   Tip Fry in small batches so the oil stays hot and the fries do not steam.
4. 4Add the marinara
   Pour off most of the frying oil, leaving a thin film in the skillet. Return the fries to the skillet and spoon the warm marinara sauce over and among them, spreading it out evenly across the pan.
   Look for The sauce coats the bottom of the skillet and surrounds the golden sticks.
   Tip Warm the marinara first so it does not cool the fries.

At the end of this phase, the fries should be a deep golden brown and crisp when lightly pressed with tongs. The outside should sound crunchy as the sticks move in the oil, and the aroma should be toasty and warm rather than burnt. Look for steady bubbling around the fries, which shows the oil is hot enough to crisp them quickly. Before moving on, drain the fries on paper towels and pour off most of the oil from the skillet, leaving a thin film. The fries should feel firm and dry to the touch, ready to take the sauce without going soggy in the pan.

Melting and tossing

5. 5Melt the provolone
   Lay the thin provolone slices over the top of the fries so they cover them. Cover the skillet loosely or leave it open, and cook over medium heat until the cheese melts into a glossy, stretchy layer over the crispy fries.
   Look for The cheese is fully melted, glossy and stretches when lifted.
   Tip Keep the heat moderate so the cheese melts without scorching the bottom.
6. 6Toss and garnish
   Toss the fries gently with tongs, pulling the molten cheese and sauce through the sticks. Scatter chopped fresh parsley over the top and sprinkle with the reserved grated provolone. Serve hot, straight from the skillet.
   Look for Cheese and sauce are evenly distributed and the parsley looks bright green.
   Tip Serve immediately while the cheese is still stretchy.

At the end of this phase, the provolone should be fully melted into a glossy, stretchy layer that pulls away in strands when lifted with tongs. The marinara should be bubbling gently around the fries, and the parsley should look fresh and bright. Check that the cheese has covered the fries evenly and that the bottom of the skillet is not scorched.

Toss gently so the sauce and cheese are distributed through the sticks while the outside stays crisp. Once the fries are coated and the garnish is scattered on top, serve immediately, because the cheese firms up as it cools and the crisp edges soften over time.

Common mistakes

The most common mistake is slicing the polenta while it is still soft. A warm or loose block will crumble in the oil and turn the fries ragged, so chill it until it is clearly firm. Another error is crowding the skillet: too many fries at once drop the oil temperature, and the sticks steam instead of crisping. Fry in batches and let the oil return to heat between them.

Do not add the marinara before the fries are fully golden, or they will lose their crunch. Finally, avoid overheating the cheese over high heat, which can make it grainy and scorch the pan. Keep the heat moderate once the sauce and provolone are in, and toss at the end rather than stirring vigorously, so every fry stays intact.

How to tell it’s done

The fries are done when they are deep golden brown and crisp to the touch on every side, with no pale or soft spots. They should feel firm when pressed gently with tongs. The finished dish is ready when the provolone has melted into a glossy, stretchy layer over the fries and the marinara is bubbling at the edges. Polenta is cooked before it is fried, so there is no raw protein here to check with a thermometer. Judge the fries by colour, texture and the melted cheese, and serve as soon as the cheese is smooth and the fries are crisp and hot.
