Time 1h

Number Of Ingredients 11

1 tablespoon olive oil, plus more for pan and baking sheet
1 recipe Soft Polenta
2 tablespoons olive oil
1/2 large red onion, finely chopped
2 packages (10 ounces each) white or cremini mushrooms, halved (or quartered, if large)
Coarse salt and ground pepper
1/2 teaspoon crushed dried rosemary
2 tablespoons tomato paste
1 teaspoon balsamic vinegar
4 ounces goat cheese, crumbled (about 1 cup)
Wilted Spinach and Cherry Tomatoes, optional

Steps:

Brush an 8 1/2-by-4 1/2-inch loaf pan lightly with oil. Pour soft polenta into pan; smooth top. Cover with plastic wrap, and refrigerate until chilled and firm to the touch, about 3 hours and up to 3 days.
Meanwhile, make mushroom ragout: In a large skillet, heat oil over medium. Add onion; cook, stirring often, until soft, about 5 minutes. Add mushrooms; season generously with salt and pepper. Cover and cook until mushrooms release their juices, about 10 minutes.
Uncover pan; raise heat to high. Cook, stirring often, until liquid has evaporated and mushrooms are brown, 2 to 3 minutes. Add rosemary, tomato paste, and 2 cups water. Simmer until sauce has thickened, 10 to 15 minutes. Stir in vinegar.
Meanwhile, heat broiler. Invert polenta onto a cutting board: cut into 12 to 14 slices, each 1/2 inch thick. Brush a rimmed baking sheet with oil. Arrange slices in a single layer; brush with oil. Broil 4 inches from heat, without turning, until golden and browning in spots, 10 to 20 minutes. Divide among plates; top with mushroom ragout, and sprinkle with goat cheese. Serve with Wilted Spinach and Cherry Tomatoes, if desired.
