Equipment You’ll Need

• Large, heavy-bottomed saucepan or Dutch oven
• Whisk
• Silicone spatula
• 9×9 inch baking pan
• Parchment paper
• Chef’s knife
• Cutting board
• Large skillet (cast iron or non-stick) or a large baking sheet
• Tongs or a fish spatula

Ingredients

• 4 cups vegetable or chicken broth (or water)
• 1 teaspoon kosher salt, plus more for sprinkling
• 1 cup coarse or medium-grind cornmeal (polenta)
• 1/2 cup freshly grated Parmesan cheese
• 2 tablespoons unsalted butter
• 1 tablespoon fresh rosemary, finely chopped
• 1/2 teaspoon freshly ground black pepper
• 3-4 tablespoons olive oil or neutral oil, for frying

Instructions

1. Prepare the Pan: Lightly grease a 9×9 inch baking pan and line it with parchment paper, leaving an overhang on two sides to act as handles. This will make it easy to lift the set polenta out later.
2. Cook the Polenta: In a large, heavy-bottomed saucepan, bring the broth and 1 teaspoon of salt to a rolling boil over medium-high heat.
3. Whisk in Cornmeal: While whisking constantly, slowly pour the cornmeal into the boiling liquid in a thin, steady stream. This gradual addition is key to preventing lumps.
4. Thicken the Polenta: Reduce the heat to low and continue to cook, switching from a whisk to a spatula. Stir frequently, scraping the bottom and sides of the pot, for 15-20 minutes. The polenta is ready when it is very thick, pulls away from the sides of the pot, and can hold its shape.
5. Add Flavorings: Remove the pot from the heat. Stir in the grated Parmesan cheese, butter, chopped rosemary, and black pepper until the cheese and butter are completely melted and incorporated.
6. Chill the Polenta: Immediately pour the hot polenta into the prepared baking pan. Use the spatula to spread it into an even, smooth layer. Let it cool on the counter for about 20 minutes, then cover with plastic wrap and transfer to the refrigerator. Chill for at least 2 hours, or until completely cold and firm. This can be done up to 3 days in advance.
7. Cut into Squares: Once firm, use the parchment paper handles to lift the polenta block out of the pan and onto a cutting board. Use a sharp chef’s knife to cut the block into 16 equal squares (a 4×4 grid).
8. Cook the Squares (Frying Method): Heat the olive oil in a large skillet over medium-high heat. The oil should shimmer but not smoke. Carefully place the polenta squares in the pan in a single layer, being careful not to overcrowd it (work in batches if necessary). Fry for 4-5 minutes per side, until a deep golden-brown crust forms. Transfer to a paper towel-lined plate and sprinkle with a little extra salt.
9. Cook the Squares (Baking Method): Preheat your oven to 425°F (220°C). Arrange the squares on a baking sheet lined with parchment paper. Brush the tops and sides generously with olive oil. Bake for 20-25 minutes, flipping halfway through, until golden brown and crispy on the edges.
10. Serve Immediately: For the best texture, serve the polenta squares while they are hot and crispy. Garnish with extra rosemary or Parmesan if desired.

Expert Cooking Tips

• Whisk Constantly: The most crucial step for smooth polenta is to pour the cornmeal in a very slow stream while whisking vigorously. This prevents clumping.
• Use Broth for Flavor: While water works, using vegetable or chicken broth imparts a much deeper, more savory flavor into the polenta from the start.
• Patience is Key: Don’t rush the cooking process. The polenta needs time on low heat to fully hydrate and become creamy. If it seems too thick, you can add a splash more broth.
• Ensure it’s Fully Chilled: Do not attempt to cut or fry the polenta until it is completely cold and firm to the touch. Warm polenta will fall apart.
• Hot Pan, Crispy Crust: For frying, make sure your oil is sufficiently hot before adding the squares. This creates an instant crust and prevents the polenta from absorbing too much oil and becoming greasy.

Substitutions and Variations

For a vegan version, use vegetable broth, substitute the butter with a high-quality olive oil or vegan butter, and replace the Parmesan with 3-4 tablespoons of nutritional yeast for a cheesy, savory flavor. Feel free to experiment with herbs; thyme, sage, or chives are also delicious.

Common Mistakes to Avoid

The most common mistake is lumpy polenta, which is avoided by slowly adding the cornmeal while whisking. Another pitfall is trying to fry polenta that isn’t fully chilled, causing it to fall apart in the pan. Lastly, overcrowding the skillet during frying will lower the oil temperature, resulting in greasy, soggy squares instead of crispy ones. Cook in batches for the best results.

Serving Suggestions

Serve these squares as an elegant appetizer with a side of spicy marinara or a creamy gorgonzola sauce for dipping. As a side dish, they are a fantastic gluten-free alternative to potatoes or bread, pairing beautifully with braised meats like short ribs, osso buco, or a simple roasted chicken. For a vegetarian main course, top the crispy squares with a wild mushroom ragu, caponata, or a simple poached egg and sautéed greens.

Storage and Reheating Tips

Store leftover cooked polenta squares in an airtight container in the refrigerator for up to 3 days. To reheat and restore their crispiness, place them on a baking sheet in a 400°F (200°C) oven or in an air fryer for 5-7 minutes until hot and re-crisped. The uncooked, chilled block of polenta can be wrapped tightly and stored in the fridge for up to 3 days before cutting and cooking.

Frequently Asked Questions

Can I use instant polenta for this recipe?

It is not recommended. Instant polenta has a different texture and does not set up as firmly as traditional cornmeal, which is necessary for cutting and frying the squares.

Why did my polenta squares fall apart when I fried them?

This usually happens for two reasons: the polenta wasn’t cooked long enough to become thick and sturdy, or it wasn’t chilled for a long enough time to become completely firm. Ensure it’s rock-solid before cutting.

Can I freeze the polenta squares?

Yes. You can freeze the cut, uncooked squares. Place them on a baking sheet in a single layer and freeze until solid, then transfer to a freezer bag. Cook them directly from frozen, adding a few extra minutes to the cooking time.
