Stephen's Stroganoff

I made this up on the fly last night, and it was amazing, so I thought I'd share:

Stephen’s Stroganoff

1 lb sirloin or stew meat

1 tablespoon garlic powder

1 tablespoon onion powder

2 tablespoons kosher salt

1 tablespoon black pepper

½ onion chopped

1 can cream of mushroom soup

1 can sliced mushrooms drained

1 teaspoon cayenne pepper

4 teaspoons brown sugar

½ cup cream

1 cup sour cream

Slice sirloin into bite sized strips. Sprinkle steak with garlic powder, onion powder, salt, and pepper. Put in large skillet and sear. Remove from skillet, and add chopped onion. Brown onion until soft (about 5 minutes or just before caramelized). Return the meat to the onions. Then add the cream of mushroom soup, sliced mushrooms, cayenne pepper, and brown sugar. Bring mixture to boil. Reduce heat, and simmer 25 minutes. Then add cream and sour cream. Simmer for 5 minutes. Salt and pepper to taste. Serve over egg noodles.
