1/4 cup olive oil, plus more for drizzling
1 large leek, or two small leeks, greens and all thinly sliced (about 1 pound)
1 bunch raab, any variety
4 cloves garlic, minced
1 teaspoon salt
1/4 teaspoon pepper
1 pound pasta (linguine or other long, thin shape)
Saute leek over medium heat in olive oil, stirring occasionally until golden brown, about 15-20 minutes. Make sure heat is low enough so leeks don’t burn or cook to quickly.
Meanwhile, bring several quarts of water to a boil in a medium saucepan. Roughly chop the whole bunch of raab — stems, leaves and all. Pop them into the boiling water for 2 minutes, and then drain them and set aside.
Add the garlic to the pan with the leeks and cook for just one minute. Then add the raab and salt and pepper and cook everything together, stirring occasionally, until the raab is tender, about 5 minutes. Taste for salt and pepper and adjust as desired.
While preparing the leek sauce, cook and drain the pasta, making sure that some liquid still sticks to the noodles. Toss the hot pasta with the raab-leek sauce. Mix well and transfer portions to warm pasta bowls. Drizzle each bowl with olive oil to taste and serve immediately.
