Cheesy Polenta Fries with Marinara: Crispy, Gooey and Ready in One Skillet Step-by-step instructions

Before you start

Gather everything before you turn on the heat, because this dish moves quickly once the skillet is hot. Set out the polenta fries, the olive oil, kosher salt, black pepper, the marinara and the provolone. Peel and thinly slice the garlic cloves, mince any remaining garlic, slice the red chili pepper into thin rounds and chop the parsley finely on a wooden cutting board.

Grate the provolone on the large holes of a box grater into a fine pile of shreds and set it aside on a small plate. Cut the rest of the provolone into thick slices so they are ready to lay across the sauce. Having the sauce spooned into a bowl and the cheese already prepared means you can move from one phase to the next without pausing.

Instructions

Prep and arrange the fries

1. 1Prepare the fries and aromatics
   Cut the polenta into fries if needed. Peel and thinly slice the garlic cloves, slice the red chili pepper, mince the remaining garlic, and chop the parsley on a wooden cutting board. Grate the provolone on the large holes of a box grater into a fine pile of shreds, and cut the rest into thick slices.
   Look for The garlic is thinly sliced and minced, the chili is in rounds, and the cheese is in a fine shredded pile.
   Tip Chill the cheese slightly before grating so it shreds cleanly and does not smear on the grater.
2. 2Arrange the fries in the skillet
   Heat a cast iron skillet over medium heat. Add the olive oil, then arrange the polenta fries around the pan in a single layer, leaving the center open. Season the fries lightly with kosher salt and black pepper.
   Look for The oil shimmers and the fries sit in an even ring with space in the middle.
   Tip Do not crowd the pan, so the fries crisp on their edges instead of steaming.

At the end of this phase, the polenta fries should be arranged in an even ring around the cast iron skillet, each one lightly coated with olive oil and seasoned with kosher salt and black pepper. The oil should shimmer gently across the base of the pan, and the fries should sit with small gaps between them so the heat can reach every side.

Before going on, check that the center of the skillet is open and clear, and that no fries are stacked or crowded on top of one another. The garlic, chili, parsley and cheese should all be prepared and close at hand, so the next phase flows smoothly without any delay.

Add sauce and cheese

3. 3Add the marinara and provolone
   Spoon a generous portion of chunky marinara sauce over the center of the skillet. Lay the thick provolone slices on top of the sauce so they cover it. Scatter the sliced garlic and chili over the cheese, then return the skillet to medium heat.
   Look for The sauce is spread over the center and the cheese slices cover it fully.
   Tip Spoon the sauce into the middle, not over the fries, so the crust stays crisp.
4. 4Melt the cheese into the sauce
   Cook over medium heat until the provolone softens, begins to melt into the marinara and the fries turn golden at their edges. Keep the heat steady so the sauce bubbles gently without scorching.
   Look for The cheese has softened, the edges of the sauce are bubbling and the fries are golden.
   Tip Watch the bottom of the pan closely, as the cheese can catch quickly once it melts.

At the end of this phase, the marinara should be spooned generously over the center of the skillet, and the thick slices of provolone should cover the sauce completely. The sliced garlic and chili should be scattered over the cheese, and the sauce should begin to bubble gently at its edges as the skillet heats. The cheese should look soft at its surface and start to lose its shape. Before going on, check that the fries remain free of sauce, so their edges stay crisp, and that the heat is steady and moderate, not high, so the cheese melts evenly without scorching on the bottom of the pan.

Melt, toss and serve

5. 5Toss until coated and finish
   Use tongs to toss the fries through the molten provolone and marinara until every piece is coated. Transfer to plates, then sprinkle with the chopped parsley and the grated provolone. Serve right away while the cheese is still gooey.
   Look for Each fry is glossy with sauce and cheese, and the grated cheese begins to soften on top.
   Tip Serve immediately, as the fries lose their crispness as they cool.

At the end of this phase, the provolone should be fully softened and melted into the marinara, creating a glossy, bubbling pool across the center of the skillet. The fries at the edges should show golden color, and the whole pan should smell rich, savory and toasty. Before going on, use tongs to test one fry, lift it gently and confirm that the cheese stretches and clings to it. The grated provolone and chopped parsley should be ready to sprinkle over the finished dish. Serve immediately, while the cheese is still molten and the polenta is still crisp on its edges.

Common mistakes

The most common mistake is crowding the skillet. If the fries overlap or sit tightly packed, they release moisture and steam instead of browning, and the result is soft rather than crisp. Use a pan large enough for a single layer, and arrange the fries around the edge so the center stays open for the sauce and cheese. Another frequent error is spooning the marinara directly onto the fries.

The sauce soaks into the polenta and softens it, so keep it in the middle, where it can bubble without spoiling the crust. Heat that is too high will scorch the cheese on the bottom of the pan before the top has melted, so keep the burner at medium and adjust gently. Finally, do not let the dish sit once it is finished.

How to tell it’s done

This dish is ready when the provolone has softened, melted into the marinara and turned glossy, and the sauce is bubbling gently at the edges of the pan. The polenta fries should show golden color on their edges and feel firm when touched with tongs. When you lift a fry, the cheese should stretch and cling to it in a smooth layer rather than slide off.

The grated cheese on top should begin to soften as it sits on the warm fries. Because this dish contains no raw meat, poultry or eggs, there is no protein temperature to reach, but the cheese should be fully melted and hot throughout before you serve. If the sauce is still thick and the cheese is only partly melted, return the skillet to medium heat for another minute and check again.
