Crispy Air-Fried Parmesan Polenta Fries with Marinara Step-by-step instructions

Before you start

Before starting, ensure the polenta is firm and cold; if using a tube, remove it from the fridge 10 minutes before slicing for easier handling. Have all your ingredients measured and ready. Line a baking sheet with paper towels for patting the polenta dry.

Set up your air fryer with a clean basket. If you are making the marinara from scratch, prepare it ahead of time or use a quality jarred version. Warm the marinara in a small saucepan over low heat while the fries cook, so it is ready when they are done.

Instructions

Prep and Coat

1. 1Prepare the polenta batons
   Slice the firm polenta tube into 1/2-inch thick slices, then cut those slices into batons about 3 inches long. Pat each baton completely dry with paper towels to remove excess moisture, which helps the coating stick and crisp up.
   Look for The batons should be uniform in size and feel dry on the surface.
   Tip If the polenta is very moist, let it rest on paper towels for a few minutes before coating.
2. 2Coat with oil and seasonings
   In a mixing bowl, toss the polenta batons with olive oil until evenly coated. In a separate shallow dish, combine the grated parmesan, Italian herbs, garlic powder, and sea salt. Roll each oiled baton in the parmesan mixture, pressing gently so the coating adheres well on all sides.
   Look for The batons should be heavily crusted with the parmesan mixture.
   Tip For an even thicker crust, dip the batons back into the mixture after a light coat of oil.

At the end of this phase, your polenta batons should be evenly cut, thoroughly dried, and generously coated with the parmesan mixture. The coating should adhere well and cover every surface.

The air fryer should be preheated, and your marinara warming on the stove. The kitchen will smell of garlic and herbs, and the polenta is ready to hit the hot air.

Air Fry to Golden Perfection

3. 3Air fry until golden
   Preheat the air fryer to 200°C (400°F). Place the coated polenta batons in a single layer in the air fryer basket, leaving space between each so they crisp evenly. Air fry for 18 minutes, shaking the basket halfway through, until the fries are deeply golden, puffed, and crackling.
   Look for The fries should be deeply golden and feel crisp when gently squeezed.
   Tip Do not overcrowd the basket; cook in batches if needed to ensure even browning.

After 18 minutes of air frying, the fries should be deeply golden brown, puffed, and crackling. The air fryer will release a wonderful aroma of toasted parmesan and herbs. Shake the basket halfway to ensure even cooking. The fries should look crispy and inviting, with no pale spots. They are ready to be garnished and served immediately.

Finish and Serve

4. 4Garnish and serve
   Transfer the hot polenta fries to a serving platter. Dust with extra grated parmesan and sprinkle with chopped fresh parsley. Serve immediately with warm marinara sauce on the side for dipping.
   Look for The fries should be hot, crispy, and fragrant with parmesan and herbs.
   Tip Serve right away for the best crunch; they soften as they sit.

Once garnished with extra parmesan and parsley, the fries should be served immediately while hot and crunchy. The marinara should be warm and ready for dipping. The presentation is vibrant and appetizing, with golden fries and red sauce contrasting beautifully. Each bite should deliver a loud crunch followed by a creamy, cheesy interior.

Common mistakes

One common mistake is not patting the polenta dry enough, which causes the coating to become soggy and fall off. Take the time to thoroughly dry each baton with paper towels. Another pitfall is overcrowding the air fryer basket, which prevents proper air circulation and leads to uneven browning.

Cook in batches if necessary. Also, avoid using pre-shredded parmesan, as it often contains anti-caking agents that prevent melting and crisping. Finely grate a block of parmesan for the best results.

How to tell it’s done

The polenta fries are done when they are deeply golden brown and feel crisp on the outside. To test, gently squeeze one with tongs — it should feel firm and crunchy, not soft or doughy. The interior should be creamy and hot.

If using an instant-read thermometer, the center of a fry should register at least 165°F (74°C) to ensure it is heated through. Let the fries rest for a minute before serving to allow the crust to set, but serve them warm for the best texture.
