Penne with Artichoke Sauce

Heat oil in a large saucepan over medium heat. Add onion and cook, stirring, until limp and translucent, about 5 minutes. Add garlic and cook, stirring, for 1 minute.

Cut the trimmed artichokes lengthwise into thin wedges and add to the pan along with 3/4 cup water. Bring to a boil. Cover, reduce heat to low, and simmer, stirring occasionally, until the artichokes are tender, about 10 minutes. Increase heat to high, add wine and oregano; cook, stirring, for 30 seconds. Remove from the heat.

Transfer about 1/3 of the artichoke mixture to a blender or food processor, add the remaining 1/4 cup water and puree until smooth. Return the puree to the pan containing the remaining artichoke mixture. Season with salt and pepper.

Meanwhile, cook pasta in a large pot of boiling salted water until just tender, 8 to 10 minutes or according to package directions. Drain and add to the artichoke sauce. Toss well and serve.
