Instructions

This recipe could not be simpler! First, place the chuck roast in a 6–8 quart slow cooker. To really lock in flavor, pierce the roast all over using a fork or knife, then sprinkle the seasonings evenly over the top. Next, pour the juice around the sides of the roast and pile the peppers right on top.

Then, cook on low for 8–10 hours. If I’m home, I like to cook it on high for the first hour and then switch to low for 7–8 hours — this just helps get everything started a little quicker. Once the cooking time is up, check for tenderness; the roast should be fall-apart tender.

After that, remove any excess fat and shred the beef, either directly in the slow cooker or on a cutting board. Return the meat to the juices, stir well, and keep the slow cooker on warm. Meanwhile, toast the hoagie buns, add the cheese so it melts, and finally, pile on the shredded beef. I also love destemming a few of the peppers and loading those onto my sandwich for extra flavor. This is a repeat meal in our house for a reason!

Equipment

I love having slow cookers of different sizes. However, if I could only have one that was inexpensive and a decent size, I would get this one for sure! If you would like to see my favorite slow cookers click here!

Storage

This recipe is perfect for leftovers! It actually tastes even better the next day. It is also fantastic frozen. I like to freeze individual servings so my family can grab a sandwich size anytime they need to take a lunch or dinner to go.

FAQs

Will 2 jars of peperoncinis be to spicy?

I find that this is the perfect balance for my family. A little spice but a great tangy taste. You can certainly use one jar and add a bit of stock or water and add more as you repeat the recipe later.

What kind of cheese is best for the sandwiches?

I love a very thin sliced provolone and even better a thin pepper jack!

Can I use rump roast instead?

Yes, you certainly can. However, rump roasts tend to be a bit tougher. Allow extra cooking time.
