Shockingly Simple French Dip Sandwiches

This post may contain affiliate links. Read our disclosure policy.

I got the recipe shockingly simple French dip sandwiches from Mel’s Kitchen Café. Her cooking is always right up my alley. This recipe is now in my tried and true file under shockingly simple. I love it when I find a recipe that is just too easy, yet so delicious. My whole family gave this one a thumbs up.

Now, I did do three things different than the original recipe. First, my family loves provolone, so I used that instead of mozzarella. Second, I only used one pepper total.  Lastly, I pan fried my peppers and onions on the stove in a little butter. Only my oldest son and I are the only ones who will eat the peppers and onions.  That’s why I reduced it to one pepper. Also, by cooking the peppers and onions separately, those that want them can put them on their sandwich.  Those that don’t, can leave them off.  Absolutely delicious!

I originally made the sandwiches on homemade hot dog buns the first time I made them. However, store bought buns work well and is what I used in the photo.

Frequently Asked Questions

Can I use any type of roast for these sandwiches?
A beef chuck roast works well for tenderness and flavor, but other cuts like sirloin or round roast can be used.

Should I sear the roast before placing it in the slow cooker?
Searing adds flavor, but it’s optional. If time allows, searing can enhance the overall taste.

Are these other toppings for these sandwiches?
In the recipe, it says to use provolone of mozzarella cheese. However, Swiss is another good option. I also prefer to cook the pepper and onions in a skillet rather than in the slow cooker with the roast. Caramelized onions are another good option.
