Amazing Beef Sherry Bake

This is a great winter recipe...very hearty and delicious!

Ingredients:
~1 lb of cubed beef (cut into bite-size pieces)
1 medium red onion
1 pkg portabello caps, chopped
sherry cooking wine
beef broth
a bit of flour for thickening
unseasoned croutons (don't use seasoned!)
your favorite cheese for topping.

Directions:
Preheat oven to 375 deg. F.
Cut up the onion.  Place in bottom of a 8x8 glass baking dish.
Put beef on top of onion, and chopped mushroom on top of beef.
Add beef broth and sherry to almost cover the ingredients.  (2:1  broth:sherry)
Cover with aluminum foil and bake for ~40 minutes.
Remove from oven after 40 mins.  It should look like this:

Mix a few tablespoons flour with a little cold water in separate glass with a fork to mix completely and get rid of any clumps.  Add to the mixture while stirring to thicken to your preferred thickness.  3 tbsp should do the trick depending how much water you use.
Cover with a layer of croutons and sprinkle with as much cheese as you like-

Bake uncovered for another 5-10 minutes, until croutons are browned and cheese is melted.

Serve with egg noodles and veg of your choice;  this night I sauteed some green beans in butter-

Enjoy!  This is great reheated as leftovers as well :)
