Equipment

  • 10x8 inch baking dish
  • Baking Sheet
  • Medium Saucepan
  • Chef’s Knife
  • Silicone Spatula

Ingredients
  

If using pre-cooked polenta:

  • 1 package 500g / 17.5oz pre-cooked polenta
  • 2 tbsp olive oil
  • 1 sprig fresh rosemary finely chopped
  • 1 tsp dried oregano
  • Pinch of salt and pepper optional

If using quick-cook polenta:

  • 1 cup 190g quick-cook polenta
  • 3 1/3 cups 800ml chicken or vegetable stock
  • 4 tbsp 60g butter
  • ½ cup 30g freshly grated parmesan
  • 2 sprigs fresh rosemary finely chopped
  • 2 tsp dried oregano
  • ½ tsp sea salt flakes
  • Pinch of pepper
  • 1 tbsp olive oil

Instructions
 

  • Prepare Pre-Cooked Polenta (Optional Step): Remove the pre-cooked polenta from its packaging and gently pat it dry with a paper towel to remove any excess moisture.
    This ensures the fries crisp beautifully in the oven without steaming.
  • Cut Into Fries: Using a sharp chef’s knife, slice the polenta into evenly sized sticks, roughly ½–¾ inch thick.
    Uniform sizing is key for consistent cooking and golden edges on every fry.
  • Season and Toss: In a large mixing bowl, combine olive oil, finely chopped rosemary, dried oregano, and a pinch of pepper.
    Add the polenta fries and gently toss to coat each piece evenly in the aromatic herb oil mixture.
  • Arrange for Baking: Lay the fries in a single layer on a lined baking sheet, ensuring they don’t touch.
    Proper spacing allows hot air to circulate and prevents soggy edges, giving a perfectly crisp texture.
  • Bake Until Golden: Preheat the oven to 430°F (220°C) and bake the fries for 30–40 minutes, flipping halfway through.
    Watch for a golden-brown color and crispy exterior, while keeping the centers tender and creamy.
  • Quick-Cook Polenta Option: Bring chicken or vegetable stock to a gentle boil in a medium saucepan, then gradually whisk in the polenta.
    Stir continuously until thickened, then incorporate butter, parmesan, herbs, and salt.
    Pour into a lined baking dish and chill for at least 1–2 hours until firm.
  • Final Baking Step: Once chilled, cut the set polenta into fries, brush lightly with olive oil, and bake on a lined tray at 430°F (220°C) for 30 minutes,
    turning halfway, until golden, crisp, and ready to serve with dips, steak, or as a wholesome snack.

Notes

  • Pat pre-cooked polenta dry before slicing to ensure crispiness.
  • Cut fries into similar sizes for even cooking.
  • Season lightly if using pre-cooked polenta, as some brands are already salty.
  • Chilling freshly made polenta for at least 1–2 hours is crucial for firm fries.
  • Olive oil can be substituted with avocado or sunflower oil for different flavors.
  • Fries can be baked or lightly pan-fried for a crunchier exterior.
  • Leftover fries freeze well, either before or after baking, for easy future meals.
