This recipe came from my sister in law but with my couple slight changes.
~4-5lb ish Rib Eye Roast (I bought at Costco) Yes it's one of their most expensive cuts of beef. Very worth it though!!
~3/4 cup Mayonnaise
~roughly 2 TBSP Kosher Salt
~roughly 2 TBSP Montreal Steak Seasoning
Mix together until combined.
~1 Sweet Onion sliced and sauteed.
~Sliced Cheese-Any kind you like (We use American Swiss that our Costco carries, but most other Costco's don't carry.) I hate swiss cheese, this taste nothing like swiss-it's so good!!
Line your Slow Cooker with foil. Sprinkle the bottom with roughly 3 TBSP Kosher Salt and Montreal Steak Seasoning.
Place Roast on top of seasoning in Slow Cooker. Cover remaining exposed sides of roast with mayonnaise paste that you made.
Cover top of cooker with foil and place lid on top of that.
Cook on High until roast reaches 155 F. (About 4 hours) Turn off heat and let sit for about 30 minutes.
Slice as thin as possible or as you would prefer. Place on hogie buns with sliced cheese and sauteed onions serve with ajue dipping juice.
I have a meat slicer so I use that to get it as this as possible. I like mine super duper thin. I then throw all the meat back into the meat juice that's in the crock pot. It keeps the meat warm, flavorful and nice and juicy!!
This will easily make 15+ sandwiches.
I have frozen the meat with it's juices and it's just as good reheated.
You can also cut the roast into smaller portions (3 even pcs) and cook each individually when you are ready. I food saved the others and froze for future use. These seems to leave just enough left overs for a couple lunch meals.
If you make smaller portion roasts be sure to adjust your seasoning as well as your cooking time. It will not take as long to cook a 1.5lb roast as it does a 5lb.
