Easy Crockpot French Dip Sandwiches


  • 2 Large Onions
  • 1/4 C Butter
  • 1/2 C Soy Sauce
  • 1 1/2 tsp Gravy Master
  • 4 C Water
  • 2 lbs Deli Roast Beef
  • 1 pkg Onion Soup Mix
  • 1 clove Garlic
  • Rolls
  • Shredded Swiss Cheese



Dice onions & saute in the butter.

In crockpot mix sauteed onions with water, onion soup mix, soy sauce, Gravy Master and garlic.

Add roast beef into liquid.

Cook on low for 3-6 hours.

Serve meat on rolls with shredded Swiss cheese. Liquid can be used for dipping.


If you can’t find the Gravy Master, leave it out.

You can use a boneless roast rather than the deli roast beef-cook in the liquid for 7-9 hours, remove, slice across the grain and return to the liquid until ready to serve.

I know roast beef doesn’t seem like a “frugal” ingredient, but it’s wound up not only being a time saver but cheaper than purchasing a similar amount of boneless roast.  I purchased the absolute cheapest roast beef at Walmart and it came out great.
