Russia Marketplace at Epcot's Food & Wine Festival Beef Stroganoff

While I never had the pleasure of trying the Russia Marketplace at Epcot's Food & Wine Festival, I was very curious to try out the recipe for its beef stroganoff that I found in the official 2015 Food & Wine Festival cook book. The recipe included in this book was the same one used for the 2001 festival, when Russia shared a marketplace location with Poland. This recipe is very different from my traditional stroganoff (it does not include mushrooms but does include ketchup), so I was a little skeptical at the onset.

Ingredients

Ingredients:
1 lb beef stew meat my grocery store had sirloin steaks on sale, so I sliced that instead
5 Tablespoons all purpose flour
2 Tablespoons butter
1 medium yellow onion diced
2 cups beef broth
1 Tablespoon dijon mustard
4 Tablespoons ketchup
8 ounces sour cream
salt to taste
black pepper to taste
1 lb egg noodles cooked following package instructions

Instructions

First, lightly flatten the beef with a tenderizing mallet (I didn't need to do this because I sliced the beef into thin strips at the onset). Then use 4 tablespoons of the flour to dredge the beef pieces. I used a large ziplock bag, put in the flour and meat, sealed it, and shook until all of the meat was uniformly covered.
Then, in a large pan, melt the butter over medium heat. Add in the onions and saute them, stirring constantly for about 5-7 minutes. You want the onions to soften and look translucent.
Next, add the beef and continue stirring until all of the pieces are browned on each side. Reduce the heat to low, stir in the beef broth and simmer for about 20 minutes, stirring occasionally.
Finally, stir in the mustard, ketchup, sour cream and remaining tablespoon of flour. Add salt and pepper to taste and stir until everything is combined. Serve over hot egg noodles.
