📝 About This Recipe

These polenta fries are the ultimate transformation of humble cornmeal into a sophisticated, crispy-on-the-outside, creamy-on-the-inside snack. Originating from Northern Italian tradition, this modern take elevates the texture by double-cooking—first simmering into a rich porridge and then flash-frying to golden perfection. Infused with nutty Parmesan and fresh rosemary, they offer a comforting crunch that makes them a crowd-pleasing alternative to traditional potato fries.

🥗 Ingredients

For the Polenta Base

  • 1.5 cups Coarse ground yellow cornmeal (high quality stone-ground preferred)
  • 2 cups Whole milk (at room temperature)
  • 2 cups Vegetable broth (low sodium)
  • 3 tablespoons Unsalted butter (cubed)
  • 1/2 cup Grated Parmesan cheese (freshly grated)
  • 1 tablespoon Fresh rosemary (finely minced)
  • 1.5 teaspoons Kosher salt
  • 1/2 teaspoon Black pepper (freshly cracked)
  • 1/2 teaspoon Garlic powder

For Frying and Coating

  • 1/2 cup All-purpose flour (for dredging)
  • 2 cups Neutral oil (grapeseed or canola for shallow frying)
  • 1 pinch Flaky sea salt (for finishing)

For the Roasted Garlic Aioli

  • 1/2 cup Mayonnaise (high quality)
  • 3 pieces Roasted garlic cloves (mashed into a smooth paste)
  • 1 tablespoon Lemon juice (freshly squeezed)
  • 1 teaspoon Dijon mustard

👨‍🍳 Instructions

  1. 1

    Line an 8x8 inch square baking pan with parchment paper, leaving an overhang on the sides to act as handles for easy removal later.

  2. 2

    In a large heavy-bottomed saucepan, combine the vegetable broth and whole milk. Bring to a gentle boil over medium-high heat.

  3. 3

    Slowly whisk in the cornmeal in a steady, thin stream. This is crucial to prevent any lumps from forming in your polenta.

  4. 4

    Reduce the heat to low and cook the polenta, stirring frequently with a wooden spoon for about 20-25 minutes. The polenta is ready when it is thick, creamy, and starts to pull away from the sides of the pan.

  5. 5

    Remove the pan from the heat. Stir in the cubed butter, Parmesan cheese, minced rosemary, kosher salt, black pepper, and garlic powder until the mixture is smooth and glossy.

  6. 6

    Pour the hot polenta into the prepared baking pan. Use an offset spatula to smooth the top into an even layer, approximately 3/4 inch thick.

  7. 7

    Allow the polenta to cool at room temperature for 30 minutes, then cover with plastic wrap and refrigerate for at least 2 hours, or until completely firm and cold.

  8. 8

    Once chilled, lift the polenta block out of the pan and place it on a clean cutting board. Slice the block into uniform sticks, roughly 3 inches long and 3/4 inch wide.

  9. 9

    Place the flour in a shallow bowl. Lightly dredge each polenta stick in the flour, shaking off any excess. You want a very thin coating to help create a crust.

  10. 10

    In a large skillet, heat the neutral oil over medium-high heat until it reaches 350°F (175°C). You can test this by dropping a small piece of polenta in; it should sizzle immediately.

  11. 11

    Fry the polenta sticks in batches to avoid crowding the pan. Cook for 3-4 minutes per side, turning carefully with tongs, until they are deep golden brown and crispy on all sides.

  12. 12

    Transfer the fried polenta to a wire cooling rack set over a baking sheet. This prevents the bottom of the fries from becoming soggy.

  13. 13

    Immediately sprinkle the hot fries with flaky sea salt while the oil is still glistening on the surface.

  14. 14

    In a small bowl, whisk together the mayonnaise, roasted garlic paste, lemon juice, and Dijon mustard until well combined to create the aioli.

  15. 15

    Serve the polenta fries immediately while hot and crispy, with the roasted garlic aioli on the side for dipping.

💡 Chef's Tips

Ensure the polenta is completely chilled and firm before slicing; otherwise, the fries may fall apart in the hot oil. For an extra-crispy exterior, you can use fine semolina flour or cornstarch instead of all-purpose flour for dredging. Don't skip the resting period on the wire rack; placing them directly on paper towels can trap steam and make the crust lose its crunch. If the oil temperature drops too low, the polenta will absorb too much grease; use a kitchen thermometer to maintain a steady 350°F. You can prepare the polenta base up to two days in advance and keep it refrigerated until you are ready to fry.

🍽️ Serving Suggestions

Pair with a crisp, chilled glass of Pinot Grigio or a light Italian lager to cut through the richness. Serve alongside a spicy marinara sauce or a balsamic glaze reduction for a tangy flavor contrast. These make an excellent side dish for grilled lamb chops or a hearty Tuscan kale salad. Garnish with extra grated Parmesan and fresh parsley for a beautiful, restaurant-quality presentation. For a fun twist, serve them as 'Polenta Poutine' topped with mushroom gravy and fresh mozzarella curds.
