Marinated Flank Steak Sandwich

Mr. Devilish Dish is a grilling expert.  When the weather cooperates he almost always grills our entree and sometimes the side dishes too.  And since we've gotten the sous vide machine, we've been experimenting with cooking meat by that technique too.  So you can imagine how skeptical he was when he found out that not only does this steak recipe marinate in a casserole dish overnight, but it cooks under the broiler for only 5 minutes per side.  It turned out so fabulous, we made it again a few nights later.  With the caramelized onions and horseradish spread, you've got a hearty beef sandwich that's not only simple and quick to prepare, but full of flavor.  Have you ever heard that ol Southern saying, "There's more than one way to skin a cat?" Well it turns out there is more than one way to cook roast beef too!

I can't describe how good this is.
I wish my blog had taste-o-vision.

Marinated Flank Steak Sandwich

2 pounds flank steak
2/3 cup beer (I used Boulevard Wheat, but any kind should do)
1/3 cup vegetable oil
1 teaspoon Kosher salt
1/2 teaspoon garlic powder
1/2 teaspoon cracked black pepper
5 tablespoons unsalted butter
4 cups sliced yellow onions
1/2 teaspoon paprika
hoagie-style sandwich rolls, toasted
1 1/2 cups sour cream
1 1/2 tablespoons horseradish

Place flank steak in a rectangular casserole dish.  In a bowl combine the beer, oil, salt, garlic powder and pepper.  Pour over the streak.  Cover and marinate in the refrigerator overnight.  When ready to prepare, drain off the marinade.  Turn the broiler to high and place the rack 3-inchs from the heat source.  Cook steak 5 minutes on each side.  Meanwhile, in a saucepan on the stove, melt the butter and saute the onions until soft and caramelized.  Season with the paprika.  Combine the sour cream and horseradish in a small bowl and set aside.  When the meat is cooked and rested, thinly slice is diagonally across the grain.  Place meat slices on bun and top with onions and horseradish sauce.
