Beef Stroganoff

Our family loves this recipe.  Mushrooms would be great added to this.  I am the only one who like mushrooms, so we usually omit them.

1 tsp kosher salt
1 tsp black pepper
2 TBSP butter
1 TBSP Olive oil
1 TBSP all purpose flour
1 cup beef broth
1 medium onion, quartered and sliced
3 TBSP sour cream, room temperature

Cut beef into narrow strips (2 in long and 1/2 in thick) Sprinkle meat with salt and pepper.

heat 1 TBSP of butter and 1 TBSP of olive oil in a small sauce pan over medium heat; quickly brown meat strips and onion on all sides.  Remove meat and set aside.

To the pan Melt 1 TBSP butter. Blend in flour; gradually stir in beef broth. Stir and cook until thickened.

Add meat and onion to beef sauce.  Cover and cook on low for 10 minutes.  Remove from heat and stir in sour cream and heat through but do not boil.  Serve over egg noodles or rice.
