These French Dip Sandwiches have tender, juicy roast beef and onions cooked low and slow, and served on hoagie rolls with melted, broiled provolone cheese. The cooking broth makes an awesome Au Jus for dipping sauce. A chuck roast or rump roast is most often used for this sandwich, but this recipe also works with venison roasts.

This is an easy slow cooker crockpot recipe, and these sandwiches are perfect served on these Homemade Sub Buns.
This slow-cooked beef could also be used to make French Dip Sliders.
I LOVE a great French dip sandwich, but my husband isn’t a big fan of dipping his into the Au Jus, so instead, he spreads horseradish sauce all over his sandwich and absolutely loves it that way. Win-win!

Glad to see I've been on right track. It's hard to adjust to cooking for two after decades of cooking for a tribe, but learning. In recent months I've been making French dip sandwiches for the two of us and been doing a good job. However, every now and I need reassurances I'm on target. Although I cook the roast in the oven, you and I have like minds. Thank you for the reassurance. Plus your husband is right, my husband and I both put horseradish sauce in the sandwich.

Fabulous! Good flavor. I did add a little salt on my sandwich and horseradish. I love horseradish. I think next time, I will toast the buns, just a little, before adding the meat and cheese. I want that extra crispy bread to soak up my broth! Thanks for a great recipe. I will be making again!

Great recipe! My husband loved the au jus, however I thought it was a bit heavy on the worchestershire sauce after I made it. So I added a little brown sugar and stirred it in my bowl until melted—perfection.

Made this and used my Dutch oven because I was home. Did not have French onion soup so I used beef broth instead and it was amazing.
