Recipe: Penne With Caramelized Onions And Radicchio

Penne With Caramelized Onions And Radicchio Recipe

1 package (16 ounces) penne or ziti pasta
salt
1 large head (8 ounces) radicchio
2 teaspoons olive oil
1 jumbo onion (1 pound), thinly sliced
1 tablespoon balsamic vinegar
1/4 teaspoon coarsely ground black pepper
1 cup frozen peas, thawed
1/4 cup crumbled ricotta salata or goat cheese

In saucepot, prepare penne as label directs in boiling salted water. Drain penne, reserving 1/4 cup pasta cooking water. Return penne to saucepot.

Meanwhile, cut radicchio lengthwise in half. Remove core, then cut crosswise into 1/2" slices. Set aside. In nonstick 12" skillet, heat olive oil over medium heat until hot. Add onion and cook until browned and soft, about 15 minutes, stirring occasionally. Add vinegar, pepper, and 1/2 teaspoon salt; cook 1 minute longer. Increase heat to medium-high; add radicchio and cook 2 to 3 minutes until wilted.

Add onion mixture, peas, and reserved pasta cooking water to penne; toss to mix well. Serve, sprinkled with cheese.
