These sandwiches are packed with veggies like roasted red peppers, pepperoncini, and onion. Adding dairy with the provolone is not only tasty, its nutritious! Top it off with a quality hoagie bun for your grains, and you have a great sandwich for on the go, or an entire meal.
We paired these Slow Cooker Beef Sandwiches with a simple Strawberry Spinach Salad with Poppyseed Dressing. It was as easy as tossing together fresh baby spinach, crumbled feta, sliced strawberries, and Poppyseed Dressing. Yum!

If you freeze the beef, thaw it in the refrigerator overnight and then you can reheat it on the stovetop to 165 degrees F. Italian beef sandwiches whenever you want!
Top tips to make this recipe
- Be sure to remove any excess fat from your leftover roast beef before cooking in the slow cooker.
- Adjust the amount of pepperoncini if you like it more or less spicy. I used mild, but you can also purchase it spicy if that’s what your family prefers!

Ingredients
- 1 6 pound rib roast cooked according to these instructions
- 1 ounce Italian Seasoning mix 1 packet
- 1/2 ounce beef au jus seasoning 1/2 packet
- 8 oz pepperoncini pepper slices + 2 tablespoons juice from jar use more juice if you like things spicier
- 12 ounces roasted red peppers drained and diced
- 1/2 red onion sliced
- 14.5 oz beef broth
- provolone cheese sliced
- hoagie buns
- horseradish sauce for serving
Instructions
- This is a recipe for using your leftover roast to make sandwiches. You can find a great roast recipe HERE.
- Take your leftover roast and chop into cubes, removing any excess fat.
- Place roast cubes into a large crock pot. Sprinkle with the Italian Seasoning Mix and au jus seasoning. Add in the pepperoncini, juice, roasted red peppers, and sliced onion. Pour the beef broth over everything. Stir to combine/coat.
- Cover with lid and cook on low for 2 hours or until everything is hot and the beef is easy to shred with two forks (or chop with a sharp knife). (this recipe is using COOKED roast, it is an idea for leftovers. If cooking a roast from raw, you would cook on low for 9 hours). After shredding, cook on low for another hour or until ready to serve.
- 15 minutes before ready to serve, scoop the shredded meat on half of the hoagie buns and top with provolone cheese. Spread horseradish sauce on the back of the top piece of bun. Place the top half of the bun on the sandwich. You can serve as is, or I like to wrap tightly in foil and cook in the oven (350F) for 10-15 minutes or until cheese and bun are hot.
- Serve and enjoy!

Nutrition Information
Hi, I have not made this yet, waiting on an answer to a question so I’ll give it a 3 because you have to give it something. My question is how many pounds of LEFT-OVER beef do you need for this recipe? 6-pounds is what you start with but I can’t imagine anyone have 6 pounds left-over, so that’s my question how many left-over pounds for this dish? TIA!
We can’t give an exact number, as the bone size and weight can vary greatly. You will probably lose anywhere from 10-15% of the weight once the bones are removed, so we would aim for about 5 pounds of leftover beef.
Thanks, but you and I have different ideas of what left-overs are. Dictionary.com says left·over NOUN leftovers (plural noun) something, especially food, remaining after the rest has been used. Seems like it might be an excellent recipe but I’m looking to use left-over beef. I’ll save it for a party. Thanks again.
Hi Vicky, You asked how many pounds of leftover beef would be needed for this recipe. You’ll need 5 pounds of leftover beef to make the recipe as written, or you can budget for about 1/2 pound per person and reduce the remaining ingredients to suit. This recipe does serve 12 people, so you can adjust accordingly.
I made this last winter with LEFTOVER Prime Rib. It was delicious. I put the leftover slices in and did the rest the same. Experiment with it based on taste. The seasoning packets might seem too salty. If I remember correctly, I halved the packets from what the recipe quoted.
Sweet Becky , Your delicious recipes are getting me through the sadness of every day news. Thank you so much💚💜💙🧡❤
I’m glad I could help, even just a bit! Hope you are staying safe and well :)
I am always looking for ways to use my left over roast beef. Can this be used with a round roast or rump roast? Where do I get the roasted red peppers?
i could eat these daily!
Me too, they’re sooo good!!
Can this be made with a pork roast?
Thanks
From lexibites.com
Yes, absolutely!
What a genius way to use up leftovers. I love the juiciness of the meat and that it tastes nothing like leftovers!
