I love french dip sammies! They have always been a favorite of mine. I modified this recipe from one I found on http://www.allrecipes.com/. We ate it with some sweet potato fries and lots of Au Jus....
French Dip with Au Jus
3-4 lb beef roast
1 onion thinly sliced
1-2 cloves garlic, smashed and skins removed
1 T. tomato paste (or ketchup)
2 T. worcestershire sauce
2 cans beef broth
2 cans beef consumme soup or 2 cans french onion soup
1 12 oz bottle or can of beer (don't freak out - the alcohol cooks out, and the flavor it makes is to die for!!)
Season the roast with salt, pepper, and garlic salt. Add the roast and all the rest of ingredients to your favorite crock pot and cook on low for about 7-8 hours. (until you can shred the roast with a fork). Shred the roast and put back in the Au Jus.
provolone cheese, sliced
Split Hoagie rolls, brush with melted butter and broil in oven until lightly toasted. Add provolone cheese and continue broiling until melting (1 or 2 minutes). Place shredded beef on each hoagie and serve with juices left in crock pot for dipping!
