My favorite beef stroganoff!

This is another Allrecipes find. I've changed it up a bit.. but man, this is gooood!

BEEF STROGANOFF:
2 pounds sirloin steak, cut into thin strips
1/4c. all purpose flour with salt and pepper
2T. butter, divided
2 large onions, chopped
1 (10.5 ounce) can beef broth (I add more or less depending on how saucy I want it)
1-2t. dried basil
salt and pepper to taste
2c. sliced mushrooms
1T. Worcestershire sauce
1.5c. sour cream
cooked rice or egg noodles

Dredge the meat in flour. In a skillet, melt 1T. butter over medium heat; saute onions until tender. Remove from pan; set aside. Melt remaining butter and brown meat on all sides. Add broth, basil, salt and pepper, mushrooms, Worcestershire sauce and onions. Cook until mixture thickens, about 5 minutes. Just before serving, stir in sour cream. Heat through, but do not boil. Serve immediately over rice or noodles.
