Ingredients

• Olive oil for brushing
• 3 1/4 cups cold water
• 1 cup polenta (not quick-cooking)
• 1 teaspoon chopped sage
• 1 teaspoon chopped rosemary
• 1/2 cup grated Parmigiano-Reggiano
• 2 tablespoons unsalted butter, cut into bits

Instructions

1. Brush an 8-inch square baking dish with oil.
2. Combine water, polenta, herbs, and 3/4 teaspoon salt in a heavy medium saucepan and bring to a boil over medium heat, whisking. Reduce heat to medium-low and cook, stirring constantly with a long-handled wooden spoon, until polenta begins to pull away from side of pan, 15 to 20 minutes. Stir in cheese and butter until incorporated, then transfer polenta to baking dish, spreading evenly with a dampened rubber spatula. Chill, uncovered, until set, about 45 minutes.
3. Preheat broiler. Line a baking sheet with foil and brush with oil.
4. Unmold polenta, then cut into 16 (about 4- by 1-inch) sticks. Brush tops with oil and space evenly on baking sheet. Broil about 4 inches from heat until golden, 15 to 20 minutes.
