Crock Pot French Dip Au Jus

Barbara found this French dip recipe in the Pot O’Gold cookbook from our Great-Aunt Gertie’s church out in Imogene, Iowa, and it did not disappoint. Adding the cheese and putting the sandwiches back under the broiler takes them from a good sandwich to a delicious sandwich.

You do have to do a bit of prep work before it is ready for the crockpot but cooking the onions in the butter and mixing together the seasonings is totally worth it.

Do you need a tool to easily shred beef? Buy a pair of kitchen shears or put your cooked meat in your kitchen aid with the paddle attachment. After a little bit, you’ll have perfectly shredded meat.

Recipe FAQs

Use whichever type of beef roast you have on hand. Or, try a pork roast!
Substitute 1 tablespoon minced, dried onions for onion soup mix.
I recommend using low sodium soy sauce, if possible.
If desired, add salt and black pepper; however, soy sauce is pretty salty on its own.
Brown gravy mix could be omitted, if needed. Or, go ahead and throw the entire 1 ounce package into the crock pot. It won’t hurt a thing.
To easily shred the French dip beef, use a kitchen aid mixer to quickly shred it perfectly. I use the paddle attachment.
Take the extra effort to broil the buttered buns. It makes the sandwiches amazing!
Don’t walk away from the broiler. It doesn’t take long for the buns or cheese to burn.
Instead of making French Dip sandwiches, shred the beef and serve over mashed potatoes or rice.
