Crispy Baked Polenta Fries
Equipment
- 10×8 inch baking dish (for cooking polenta from scratch)
- baking tray
- Medium-sized pot
- Large Mixing Bowl
- Knife and cutting board
- Spoon or 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 making quick-cook polenta from scratch:
- 1 cup 190g quick-cook polenta
- 3 ⅓ cups 800ml chicken or vegetable stock
- 4 tbsp 60g unsalted butter
- ½ cup 30g freshly grated Parmesan
- 2 sprigs fresh rosemary finely chopped
- 2 tsp dried oregano
- ½ tsp sea salt flakes kosher salt
- Pinch of black pepper
- 1 tbsp olive oil
Instructions
- Preheat Your Oven: Before you begin preparing your polenta fries, preheat your oven to 430°F (220°C). This ensures your fries bake evenly and develop a golden, crispy exterior. If you’re making polenta from scratch, allow enough time for both the cooking and chilling stages while the oven warms.
- Prepare Pre-Cooked Polenta (Optional): If you are using pre-cooked polenta, remove it from its packaging and pat it gently with a clean kitchen towel to absorb any excess moisture. This step is essential because excess moisture can prevent the fries from crisping properly in the oven.
- Slice Polenta Into Fries: Carefully cut the polenta into uniform fry-shaped sticks. Aim for similar thickness—roughly 1/2 inch wide and 3 inches long—so they cook evenly. Uneven sizes can result in some fries overcooking while others remain soft. Place the cut fries aside on a plate or cutting board.
- Season Pre-Cooked Polenta: In a large mixing bowl, combine 2 tablespoons of olive oil, chopped fresh rosemary, dried oregano, and a pinch of black pepper. Gently toss the polenta fries in the herb mixture, making sure each piece is evenly coated. Avoid adding salt at this stage if your polenta is already seasoned.
- Arrange Fries for Baking: Line a baking tray with parchment paper or a light coating of olive oil. Place the coated polenta fries in a single layer, leaving space between each fry to allow for even heat circulation. Overcrowding the tray can prevent them from becoming crisp.
- Bake Pre-Cooked Polenta Fries: Place the tray in the preheated oven and bake for 30–40 minutes. Halfway through, use a spatula to flip the fries to ensure they brown evenly on all sides. The fries are done when they are golden brown and have a crunchy exterior while remaining soft and creamy inside.
- Prepare Quick-Cook Polenta (Optional): If making polenta from scratch, begin by bringing 3 1/3 cups (800ml) of chicken or vegetable stock to a gentle boil in a medium-sized pot. Once boiling, reduce the heat to low and gradually whisk in 1 cup (190g) of quick-cook polenta, stirring constantly to prevent lumps.
- Enrich and Flavor Polenta: Once the polenta has thickened slightly (2–3 minutes), add 4 tablespoons (60g) of unsalted butter, 1/2 cup (30g) freshly grated Parmesan, 2 sprigs chopped rosemary, 2 teaspoons dried oregano, 1/2 teaspoon sea salt flakes, and a pinch of black pepper. Stir thoroughly until the butter melts and the ingredients are fully incorporated.
- Chill Polenta for Frying: Pour the cooked polenta into a lined 10×8 inch baking dish. Spread it evenly with a spatula and smooth the surface. Allow it to cool completely, then cover with plastic wrap and chill in the refrigerator for at least 1–2 hours, or overnight for best results. Chilling ensures the polenta firms up and can be cut into fries without crumbling.
- Slice Chilled Polenta: Once set, remove the polenta from the fridge and carefully lift it from the baking dish. Using a sharp knife, cut the polenta into fry-shaped sticks, aiming for even sizes to ensure uniform baking.
- Coat Polenta Fries With Olive Oil: Place the sliced fries on a lined baking tray and brush them lightly with 1 tablespoon of olive oil. This adds flavor and helps achieve that golden, crisp exterior.
- Bake Chilled Polenta Fries: Transfer the tray to the preheated oven and bake for approximately 30 minutes, flipping halfway through. Bake until the fries are golden brown, crunchy on the outside, and soft on the inside. Adjust the timing slightly if you prefer extra crispiness.
- Serve and Enjoy: Remove the fries from the oven and allow them to cool for a few minutes. Serve warm as a side dish with steak, grilled vegetables, or your favorite dipping sauces. These fries are also perfect as a snack or appetizer for entertaining guests.
- Storage Tip: Leftover fries can be stored in an airtight container in the refrigerator for up to 3 days. They can also be frozen either before or after baking. To reheat, bake in the oven at 400°F (200°C) until warmed through and crispy again.
Notes
- Pat pre-cooked polenta dry before slicing to remove excess moisture and ensure crispy edges.
- Uniform fry sizes are crucial for even cooking; aim for consistent thickness and length.
- Polenta can be made in advance and chilled overnight, which improves cutting and texture.
- Olive oil is preferred for coating as it promotes browning while keeping the fries light.
- Herbs like rosemary and oregano can be substituted or combined with thyme or sage for variation.
- Parmesan adds savory depth, but you can use a plant-based cheese for a vegan option.
Chef’s Secrets For Perfect Fries
Achieving the perfect balance of crispiness and creaminess comes down to three key factors preparation, seasoning, and baking technique.
First, whether using pre-cooked or freshly made polenta, ensure it’s firm and well-chilled before slicing.
This prevents crumbling and allows the fries to hold their shape.
Next, toss the fries in olive oil and herbs generously but evenly; this step creates a golden exterior while infusing flavor.
Finally, bake in a preheated oven and flip halfway through to ensure even browning.
For extra crispiness, consider a light dusting of cornstarch or fine semolina before baking—this gives the exterior a slight crunch without adding extra fat.
Serving Suggestions For Every Occasion
Crispy Baked Polenta Fries are versatile and pair beautifully with many dishes.
Serve them alongside a juicy steak, roasted vegetables, or grilled chicken for a satisfying main meal.
They also make an excellent appetizer or snack when paired with dipping sauces such as garlic aioli, marinara, or spicy tomato chutney.
For a brunch twist, top them with a fried egg and sprinkle with fresh herbs.
These fries are also ideal for meal prep; store cooked fries and reheat briefly in the oven for a fresh, crunchy texture anytime.
Storage Tips To Keep Fries Crispy
To store leftover polenta fries, place them in an airtight container in the refrigerator for up to three days.
If you plan to freeze them, arrange uncooked or baked fries in a single layer on a tray, freeze until solid, then transfer to a freezer-safe bag.
This prevents sticking and preserves texture.
Reheat frozen fries directly in a preheated oven at 400°F (200°C) until heated through and crisp.
Avoid microwaving, as it can make the fries soft and soggy.
Proper storage ensures that these fries remain just as satisfying even after a day or two.
Frequently Asked Questions
1. Can I make polenta fries ahead of time?
Yes! Cooked polenta can be chilled in the fridge for 1–2 hours or overnight. Chilling helps the fries hold their shape, making slicing and baking easier.
2. Can I make these fries vegan?
Absolutely. Use vegetable stock instead of chicken stock and substitute Parmesan with a plant-based cheese or nutritional yeast. The texture remains creamy and the flavor stays rich.
3. Should I use pre-cooked or quick-cook polenta?
Both work well. Pre-cooked polenta is convenient and fast, while quick-cook polenta gives you control over seasoning and texture. Use whichever is easiest for your schedule.
4. How can I make the fries extra crispy?
Ensure the fries are evenly coated with olive oil and spaced apart on the baking tray.
A light dusting of cornstarch or fine semolina before baking can create a crunchier exterior. Flipping halfway through baking ensures even browning.
5. Can I freeze the fries before or after baking?
Yes! Freeze them in a single layer before or after baking. When ready to enjoy, reheat in a 400°F (200°C) oven until golden and crispy. Avoid microwaving, which makes them soft.
