This is *the* ultimate sandwich for leftover roast beef, I also make this using thinly sliced leftover steak, you may adjust all amounts as desired, the amounts listed should make 6-8 sandwiches depending on the amounts used in the sandwiches --- I suggest to use crusty buns for this, they will hold the sauce better :)

Ingredients Nutrition

Directions

  1. In a skillet cook the onions in butter and oil with sugar until soft and caramelized (about 10-15 minutes) season with salt and remove with a slotted spoon to a paper towel to drain the fat.
  2. Add in the mushrooms and fresh garlic to the skillet; cook over medium heat until mushrooms begin to just turn brown; transfer to a bowl.
  3. To the same skillet add in the beef broth to deglaze the pan; simmer for 5-6 minutes scraping down any browned bits.
  4. Add in whipping cream, ketchup, Worcestershire sauce and mustard, stir for 1-2 minutes over low heat with a wooden spoon.
  5. Then add in the cooked mushrooms and beef slices to the sauce in the skillet; stir to combine.
  6. Divide the steak/sauce mixture on the bread slices.
  7. Top with Swiss cheese, sprinkle with sauteed onions, then top with remaining bread slices.
  8. Delicious!

"Oh maw Gaw Ki-en!" (Me raving about this with my mouth full of roast beef wonderfulness). This should be (probably IS) illegal in some states. "Bwess you" Yumm-oh! Angela

This made for a nice lunch. Nothing in it was overpowering which is the way I like it. I could even taste the meat. I scaled this down for 1 person. I used my judgment on how much of everything to use. The sauce boiled down to a nice rich sauce, not to runny and not to pasty.

Good sammie! I used some leftover rib eye and sauteed some bell pepper with the mushrooms. Thanks Kittencal for a nice meal. Made for All You Can Cook Buffet special.
