Penne & Shrimp in Pink Vodka Sauce

Super easy and elegant enough to entertain with.  I adore Pink Vodka Sauce and this is one of the best recipes for it.  To make this dish you will need:
1 16 ounce package of Penne
2 tablespoons butter

1/4 pound thinly sliced pancetta bacon, chopped

1/2 medium onion, diced

1/3 cup vodka

1/2 cup heavy whipping cream

1 1/2 cups tomato sauce

1 pound shrimp, peeled and deveined

Dash of red pepper flakes (optional)

1/2 cup grated Parmesan cheese

1 tablespoon fresh chopped basil

1.)  Bring a large pot of lightly salted water to a boil. Add pasta and cook for 8 to 10 minutes or until al dente; drain.

2.)  Meanwhile, melt butter or margarine in a large skillet over medium heat. Add pancetta, and saute until lightly browned. Add vodka and stir until it is reduced by half, about 4 to 5 minutes. Stir in tomato sauce and cream. Simmer uncovered for 10 to 12 minutes. Stir every few minutes.

3.)  Add in the Shrimp and if using the dash of red pepper flakes.  Continue to cook and stir.  The shrimp should only take a few minutes to cook.  Cook until they turn pink and opaque.

4.)  Stir in pasta and Parmesan cheese, and heat through.   Sprinkle with basil and serve.
