Ingredients
- 1 tablespoon Olive Oil (for sautéing garlic)
- 4 tablespoons Olive Oil (for brushing polenta before baking)
- 2 cloves Garlic (minced using a garlic press)
- 0.75 teaspoon Salt (fine sea salt)
- 2 cups Water (for cooking polenta)
- 1 cup Instant Polenta (fine instant cornmeal, approx. 150 g)
- 0.5 ounce Parmesan Cheese (finely grated on a rasp‑style grater)
- 0.125 teaspoon Black Pepper (freshly ground)
- 1 spray Vegetable Oil Spray (to grease the cake pan)
- 1 sheet Parchment Paper (cut to fit 8‑inch square pan)
Instructions
Sauté Garlic
Heat 1 tablespoon olive oil in a medium saucepan over medium heat. Add the pressed garlic and sauté for about 2 minutes, stirring, until fragrant and just softened.
Time: PT2M
Temperature: medium
Boil Water
Add 2 cups water to the pan, increase heat to medium‑high, and bring to a rolling boil. This creates a flavorful garlic‑infused broth for the polenta.
Time: PT5M
Temperature: medium‑high
Cook Polenta
Reduce heat to low. Sprinkle the instant polenta into the boiling water slowly while whisking continuously in a circular motion. Cook for 3‑5 minutes, stirring, until the mixture thickens and looks cohesive.
Time: PT5M
Temperature: low
Add Cheese and Pepper
Remove the pan from heat. Stir in 0.5 oz finely grated Parmesan and 1/8 teaspoon freshly ground black pepper until fully melted and incorporated.
Time: PT1M
Transfer to Pan
Grease an 8‑inch square cake pan with vegetable oil spray, line the bottom with parchment paper, and pour the hot polenta into the pan. Spread evenly with a spatula to a uniform thickness.
Time: PT5M
Cool on Counter
Let the pan sit on the countertop for at least 30 minutes to bring the surface temperature down before refrigerating.
Time: PT30M
Chill
Place the pan in the refrigerator and chill for at least 1 hour, or up to 2 days, until the polenta is firm throughout.
Time: PT1H
Unmold and Pat Dry
Run a thin knife or spatula around the edges, lift the parchment sheet, and flip the polenta onto a cutting board. Pat the surface gently with paper towels to remove any condensation.
Time: PT5M
Cut Triangles
Using a sharp knife, cut the slab into squares, then cut each square diagonally to form triangles. Aim for uniform size (about 2‑inch base).
Time: PT5M
Brush with Olive Oil
Arrange the triangles on a non‑stick baking sheet, leaving a little space between them. Brush the tops generously with the remaining 4 tablespoons olive oil.
Time: PT5M
Bake Until Crisp
Place the sheet on the lowest rack of a preheated oven at 375°F. Bake for 45 minutes, or until the tops are golden‑brown and crisp while the underside remains tender.
Time: PT45M
Temperature: 375°F
Serve
Remove from oven, let cool a couple of minutes, then transfer to a serving platter. Serve warm or at room temperature.
Time: PT5M

Critical Steps — Do Not Skip
- Whisk the instant polenta into the boiling liquid to avoid lumps.
- Allow the cooked polenta to chill completely before cutting.
- Pat the surface dry to remove condensation before baking.
- Brush generously with olive oil to ensure a crisp crust.
- Bake on the lowest rack at 375°F for even bottom browning.
Chef Tips from the Video
- For extra flavor, add a pinch of smoked paprika to the polenta before chilling.
- Use a microplane for the Parmesan to achieve an ultra‑fine texture that melts instantly.
- If you prefer a fully crisp triangle, flip halfway through baking, but the classic version keeps one side soft.
Troubleshooting
Polenta is lumpy after adding to water.
Whisk continuously while sprinkling the polenta slowly; if lumps form, use a fine mesh sieve to break them up.
Polenta sticks to the pan when unmolding.
Ensure the pan is well‑greased and lined with parchment; run a thin knife around the edges before lifting.
Triangles are soggy after baking.
Pat the chilled polenta dry before brushing with oil, and make sure the oven is preheated to 375°F with the tray on the lowest rack.
Storage
Refrigerator: Store leftovers in an airtight container for up to 3 days.
Freezer: Freeze individual triangles on a tray, then transfer to a zip‑top bag; keep for up to 1 month. Reheat in oven.
Room temperature: Not recommended beyond 2 hours; polenta can become soggy.
Make-Ahead Tips
- Prepare the polenta up to 2 days in advance; keep refrigerated and covered.
- After baking, reheat triangles in a 350°F oven for 10 minutes to restore crispness.
Frequently Asked Questions
What is the cultural significance and history of crisp polenta triangles in Italian-American cuisine?
Polenta is a traditional Northern Italian staple made from ground corn. In Italian‑American cooking, crisped polenta slices or triangles have become a popular appetizer and side, echoing the rustic corn mush served in Italian taverns but adapted for modern, quick preparation.
What are the traditional regional variations of polenta in Italian cuisine?
In the Veneto and Lombardy regions, polenta is often served soft with butter and cheese. In Piedmont, it may be grilled or fried after cooling. The crisp polenta triangles echo the Piedmontese “polenta fritta” tradition, but are baked instead of deep‑fried for a lighter version.
How is crisp polenta traditionally served in Italy?
Traditional Italian polenta is sliced and either grilled, fried, or baked until a golden crust forms. It is commonly paired with braised meats, mushroom ragù, or served as a base for cheese and herbs, much like these crisp triangles are served alongside roasted vegetables or salads.
What occasions or celebrations is polenta commonly associated with in Italian culture?
Polenta is a comfort food often served at family gatherings, harvest festivals, and rustic holiday meals in Northern Italy. Its versatility makes it a favorite for casual parties and buffet spreads, similar to how these crisp triangles are used for modern entertaining.
What authentic ingredients are essential for traditional polenta versus acceptable substitutes?
Authentic polenta uses coarse cornmeal and water or broth, finished with butter and cheese. In this recipe, instant polenta replaces coarse cornmeal for speed, and olive oil substitutes butter for a lighter flavor. Parmesan can be swapped with Pecorino Romano for a sharper taste.
What are the most common mistakes to avoid when making crisp polenta triangles?
Common errors include adding polenta too quickly, which creates lumps; not letting the polenta chill fully, resulting in crumbly cuts; and using too little oil before baking, which leads to sticking and a soft crust. Follow the whisking, chilling, and generous oil‑brushing steps to avoid these issues.
Why does this recipe use instant polenta instead of traditional coarse cornmeal?
Instant polenta cooks in about three minutes, dramatically reducing active cooking time while still delivering a creamy texture. Traditional coarse cornmeal would require 30‑40 minutes of stirring, making the recipe less practical for a quick home‑cooked side.
Can I make crisp polenta triangles ahead of time and how should I store them?
Yes. The polenta can be prepared up to two days in advance, chilled, cut, and kept refrigerated in an airtight container. Bake them when needed, or reheat the baked triangles in a 350°F oven for 10 minutes to restore crispness.
What texture and appearance should I look for when the polenta is done cooking on the stove?
The mixture should transition from a watery layer with visible grains to a smooth, cohesive mass that bubbles (“bloop, bloop”) and pulls away from the sides of the pan. It should be thick enough to spread without dripping.
What does the YouTube channel America’s Test Kitchen specialize in?
America’s Test Kitchen produces rigorously tested, science‑based cooking videos and cookbooks that focus on reliable, reproducible recipes for home cooks, emphasizing technique, equipment reviews, and ingredient explanations.
How does the YouTube channel America’s Test Kitchen’s approach to Italian cooking differ from other cooking channels?
America’s Test Kitchen applies systematic testing to Italian dishes, often simplifying traditional methods (like using instant polenta) while still preserving authentic flavors. Their videos include detailed explanations of why each step works, unlike many channels that rely on intuition alone.
