Ingredients

1 1/2 cups (375 ml) chicken stock
1/2 cup (125 ml / 85 g) instant polenta
1/4 cup (60 ml) finely grated Parmigiano-Reggiano (Parmesan cheese)
2 tbsp (30 ml) butter
2 tbsp (15 ml) mixed herbs, chopped finely (such as basil, oregano, thyme, flat-leaf parsley, and rosemary)
1 tsp (5 ml) kosher salt, or fine sea salt
Freshly ground black pepper
Extra-virgin olive oil for brushing

To serve (optional)

Mayonnaise or aïoli (garlic mayo), or warm tomato sauce

Instructions

Prepare an 8-inch (20 cm) baking dish by lightly spraying it with cooking oil. Line the dish with parchment paper, allowing two sides to overhang. This simple trick will create “handles” that make unmolding the firm polenta block much easier later on.
In a large, heavy-bottomed saucepan, bring the chicken stock to a rolling boil over medium heat. Ensure your stock is flavorful, as it forms the base of your polenta’s taste.
Once boiling, gradually pour the instant polenta into the hot stock. It is crucial to whisk vigorously and constantly as you pour to prevent lumps from forming. Continue to cook, whisking non-stop, for 2 to 3 minutes, or until the polenta becomes wonderfully creamy and thick, easily pulling away from the sides of the pan.
Remove the saucepan from the heat. Immediately stir in the finely grated Parmigiano-Reggiano, butter, chopped mixed herbs, kosher salt, and a generous grinding of fresh black pepper. Mix until all ingredients are well combined and the butter has melted. Spread this flavorful polenta mixture evenly into the prepared baking dish, aiming for a consistent layer about 1/2-inch (2.5 cm) thick. Transfer the dish to the refrigerator and chill for at least 30 minutes, or until the polenta is completely firm and set. This step is essential for creating fries that hold their shape.
While the polenta is chilling, preheat your oven to 425°F (220°C). Line a large baking sheet with fresh parchment paper. Once the polenta is firm, use the parchment paper overhangs to carefully lift and unmold the polenta block from the baking dish. Peel off the bottom layer of parchment paper, then transfer the block to a cutting board. Using a sharp knife, cut the polenta into even sticks, resembling traditional fries. Arrange the polenta fries in a single layer on the prepared baking sheet, ensuring they do not touch each other. This allows for even air circulation and maximum crispiness. Brush all sides of the fries generously with extra-virgin olive oil. Bake for approximately 25 minutes, flipping the fries halfway through the cooking time, until they are beautifully golden brown and delightfully crisp.
Immediately upon removing from the oven, sprinkle the hot Parmesan Polenta Fries with an additional pinch of salt to enhance their flavor. Serve them piping hot with your favorite dipping sauce, such as creamy mayonnaise, a zesty aïoli (garlic mayo), or a rich, warm tomato sauce.
MAKE IT VEGETARIAN: Easily adapt this recipe by substituting vegetable stock for chicken stock. The flavor profile will remain robust and delicious.

Key Ingredients for Perfect Parmesan Polenta Fries

Crafting the best crispy polenta fries starts with understanding the role of each ingredient. Here’s a breakdown of what you’ll need and why it matters:

Instant Polenta: This fine-ground cornmeal is the star. We use instant polenta here because it cooks rapidly and sets quickly, which is essential for forming the firm block needed for fries. While traditional polenta can be used, it requires a longer cooking time and may result in a slightly different texture, so stick with instant for this recipe’s intended results.
Chicken Stock: Far more flavorful than water, chicken stock (or broth) infuses the polenta with a savory depth right from the start. This makes a huge difference in the final taste of your fries. For a vegetarian version, simply swap in good quality vegetable stock.
Parmigiano-Reggiano (Parmesan Cheese): This hard, salty Italian cheese adds a pungent, umami-rich flavor and contributes to the golden crust. Always use freshly grated Parmigiano-Reggiano for the best flavor and melting quality. Pre-grated cheeses often contain anti-caking agents that can affect texture.
Butter: A small amount of butter enriches the polenta, adding a creamy texture and enhancing the overall flavor, making the fries feel more indulgent.
Fresh Mixed Herbs: The combination of finely chopped fresh herbs like basil, oregano, thyme, flat-leaf parsley, and rosemary brings a vibrant, aromatic freshness to the fries. Feel free to use your favorite blend or whatever you have on hand. Fresh herbs are highly recommended over dried for this recipe, as they provide a brighter flavor.
Kosher Salt or Fine Sea Salt & Freshly Ground Black Pepper: Essential seasonings that elevate all the other flavors. Seasoning the polenta correctly during the cooking process is key to a well-balanced final product.
Extra-Virgin Olive Oil: Brushing the polenta fries with olive oil before baking is crucial for achieving that desirable golden-brown, super-crispy exterior. It helps create a beautiful crust and adds a subtle fruity note.

Detailed Step-by-Step Guide for Flawless Polenta Fries

While the recipe card provides concise instructions, here are some expanded tips to ensure your parmesan polenta fries come out perfectly every time:

Preparation is Key: Don’t skip lining your baking dish with parchment paper and leaving an overhang. This simple step turns unmolding the firm polenta into a breeze and prevents any sticking.
Boil the Stock Properly: Bring the chicken (or vegetable) stock to a rolling boil. The high heat is essential for the instant polenta to cook quickly and absorb the liquid evenly.
Whisk Vigorously and Constantly: This is arguably the most critical step. As you gradually pour the polenta into the boiling stock, whisk continuously. This action prevents lumps and ensures a smooth, creamy polenta base. The polenta will thicken rapidly, usually within 2-3 minutes. Keep whisking until it’s creamy and pulls away from the sides of the saucepan.
Incorporate Flavorings Off Heat: Once the polenta is thick, remove it from the heat before stirring in the Parmesan, butter, herbs, salt, and pepper. This helps the flavors meld without overcooking the cheese or herbs.
Chill Thoroughly: Spreading the polenta into an even layer and chilling it for at least 30 minutes (or longer) is non-negotiable. This firms up the polenta, making it easy to cut into clean, defined fries that won’t crumble during baking. You can even prepare the polenta block a day in advance!
Preheat Oven and Arrange Smartly: Ensure your oven is fully preheated to 425°F (220°C). When arranging the cut polenta fries on the parchment-lined baking sheet, give them space. Overcrowding will steam them instead of crisping, leading to soggy fries. A single layer with some room between each fry is ideal.
Brush Generously with Olive Oil: Don’t be shy with the extra-virgin olive oil. Brushing all sides ensures even browning and a truly crispy texture.
Bake and Flip: Bake for about 25 minutes, but remember to flip them halfway through. This exposes all sides to the direct heat, ensuring even browning and maximum crunch.
Season Immediately: A final sprinkle of salt right when they come out of the oven enhances their savory appeal.
Serve Hot: These polenta fries are best enjoyed hot and fresh from the oven, when their texture is at its peak.

Tips for Achieving the Ultimate Crispy Polenta Fries

Getting that perfect crunch on your polenta fries is easier than you think with these expert tips:

Chill Time is Crucial: Allow your polenta block to chill completely and become very firm. This ensures clean cuts and prevents the fries from falling apart in the oven. For best results, chill for at least 30 minutes, or even an hour.
Don’t Crowd the Pan: Give your polenta fries ample space on the baking sheet. If they are too close together, they will steam instead of roast, leading to a softer, less crispy result. Use two baking sheets if necessary.
Generous Olive Oil Application: Olive oil is your friend here! Brush the fries thoroughly on all sides. This fat helps conduct heat, promoting browning and crispiness.
High Heat is Essential: Baking at 425°F (220°C) is key to achieving a crispy exterior quickly before the inside becomes too dry.
Flip Them Over: Halfway through baking, make sure to flip each fry. This exposes all sides to the direct heat, ensuring even browning and maximum crunch.
Use Good Quality Ingredients: Especially for the Parmesan cheese and fresh herbs. Their flavors will truly shine through in this simple yet elegant dish.

Delicious Variations and Customizations

While Parmesan polenta fries are fantastic as is, don’t hesitate to experiment with these delicious variations:

Cheesy Swaps: Replace Parmesan with other hard, flavorful cheeses like Pecorino Romano for a sharper taste, or a blend of Gruyère and Parmesan for a nuttier, richer profile. Asiago is another great option.
Herb & Spice It Up:
- Add a pinch of garlic powder or onion powder to the polenta mixture for extra savory depth.
- For a smoky flavor, stir in a touch of smoked paprika.
- Want some heat? A tiny dash of red pepper flakes or a pinch of cayenne pepper will do the trick.
- Consider adding finely minced sun-dried tomatoes or a tablespoon of pesto to the polenta for an Italian flair.
Make it Vegan: Simply use vegetable stock instead of chicken stock, and replace the Parmigiano-Reggiano with nutritional yeast (about 2-3 tablespoons, to taste) and the butter with a plant-based butter alternative or an additional tablespoon of olive oil.
Different Shapes: Instead of sticks, you can cut the polenta into squares, triangles, or even use small cookie cutters for fun shapes, especially if serving to children. Adjust baking time slightly for smaller pieces.
Truffle Infusion: For a truly decadent treat, drizzle the baked fries with a tiny bit of truffle oil before serving.

Perfect Pairings: What to Serve with Polenta Fries

These versatile crispy polenta fries are a perfect accompaniment to a wide range of dishes. Here are some serving suggestions:

Classic Dipping Sauces:
- Creamy Mayonnaise or Aioli (garlic mayo)
- Warm Marinara or your favorite tomato sauce
- Pesto or a basil aioli
- Spicy Sriracha Mayo for a kick
- Ranch dressing or a homemade herb dip
As a Side Dish: They pair wonderfully with grilled meats like steak, chicken, or fish. Serve alongside a juicy burger or as a sophisticated alternative to mashed potatoes.
With Salads: Add a delightful crunch to a fresh green salad or a Caesar salad.
Appetizer Perfection: Arrange them on a platter with a selection of dips for an elegant party appetizer.
Breakfast/Brunch: Believe it or not, they can be a savory side to scrambled eggs or a frittata!

Storage and Reheating Tips

These polenta fries are best enjoyed fresh, but here’s how to store and reheat any leftovers:

Storing Cooked Fries: Allow any leftover fries to cool completely. Store them in an airtight container in the refrigerator for up to 3-4 days.
Reheating for Crispness: To bring back their crispiness, avoid the microwave. The best method is to reheat them in a preheated oven at 375°F (190°C) for 10-15 minutes, or until hot and re-crisped. A toaster oven or air fryer also works wonderfully for reheating, delivering excellent results.
Making Ahead (Polenta Block): You can prepare the polenta block up to 2 days in advance. Once cooked and set in the dish, cover it tightly with plastic wrap and store it in the refrigerator. When ready to bake, simply unmold, cut into fries, and proceed with the baking instructions.

Frequently Asked Questions About Polenta Fries

What exactly is polenta?: Polenta is a dish of boiled cornmeal that was historically a staple food of Northern Italy. It can be served creamy (like porridge) or allowed to cool and solidify into a loaf, which can then be baked, fried, or grilled. In this recipe, we create a firm block to cut into “fries.”
Can I use regular polenta instead of instant polenta?: Yes, you can, but the cooking time will be significantly longer (around 30-40 minutes of constant stirring) and the liquid ratio might need slight adjustment. Instant polenta is recommended for this recipe’s ease and quick setting time. If using regular polenta, ensure it’s cooked to a very thick consistency before spreading it to chill.
My polenta fries aren’t getting crispy. What am I doing wrong?: The most common reasons for less-than-crispy polenta fries are overcrowding the baking sheet, not using enough olive oil, or the oven temperature not being high enough. Ensure good air circulation, brush generously with oil, and verify your oven temperature. Also, make sure your polenta block was thoroughly chilled and firm before cutting.
Can I deep-fry these polenta fries?: While this recipe emphasizes baking for a healthier option, you certainly can deep-fry them for an even richer, crispier result. Heat vegetable oil to 350°F (175°C) and fry in batches until golden brown, about 3-5 minutes. Drain on paper towels and season immediately. However, the baked method is designed to provide excellent crispiness without the extra fat and effort of deep-frying.
Can I add other seasonings to the polenta?: Absolutely! Feel free to experiment with garlic powder, onion powder, smoked paprika, a pinch of cayenne for heat, or even a different mix of Italian herbs. The base recipe is quite forgiving and adaptable to your taste preferences.
