Chicago Style Italian Beef Recipe (slow cooker) is so stinkin' good. It tastes just like the ones you buy in Chicago (except you need to add the peppers and onions to your sandwich). Easy peasy. Great option for any party.

Chicago Style Italian Beef Slow Cooker Sandwich with Grilled Peppers and Onions
Chicago Style Italian Beef is an easy slow cooker recipe.
Today (November 3) is National Sandwich Day so I'm reposting one of my all-time favorite sandwiches, a slow-cooker Chicago Style Italian Beef Sandwich. I have been hungry for an Italian Beef Sandwich so I decided to make one. It's excellent, and we really enjoyed it. Don said it was about as good as you can get, not being in Chicago.
I have made these sandwiches a few times for our kids and grandkids and there are never any complaints. Despite the fact that the beef is a little spicy from the pepperoncinis and pepper, they love it (at least the teenagers do!). People are far too busy eating and asking for more!
The recipe is easy. It's the waiting that's hard. When the holidays come around, remember that this sandwich is the perfect party food. Offer small crispy rolls, Crusty French Bread rolls or hamburger buns for a party. So delicious!
Types of Beef to Use
Note: You can use any boneless beef roast, such as top sirloin, top round, bottom round or chuck roast (listed most preferable to least preferable) for this recipe. If you use chuck, which is more flavorful, you will need to chill the drippings and skim the fat before eating.
What You Need
I don't know about you, but I love my Crock-Pot slow cooker. I have one like this, and it works great. I especially love that the pot can be lifted out to store or to clean. It has three settings, keep warm, low and high. In the past I've commented about using the all-in-one programmable slow cooker or an Instant Pot, but I haven't tried it so I'll leave that to your judgement. All you really need is measuring cups and spoons, some kind of slow cooker, a knife and a cutting board.

Hi Lois, This looks like a good recipe! I wanted to comment on the slow cookers, actually. I have them both and the one you covet is nice for the ability to saute and then turn down to slow cook, however, it is higher temperature than a classic ceramic slow cooker. I find that it boils on almost all settings and I need to monitor and adjust the thing a lot. I work from home so I can do that, but I do not think I would set that one and go off to work for 8 hours given that it tends to boil. It is a thin metal with non stick coating. I tried to bake bread in it, which I do with ceramic slow cookers in the summer, and the Cuisinart was too high a temperature and created hot spots that were worse than a ceramic crock. So it is NOT a replacement for a classic slow cooker, in my opinion. You can definitely make a soup in it and saute stuff first, or a one pot casserole type dish, though.
Lois
Wow. That is great to know, Jane. So maybe I don't want one of the sauté crockpots! These Italian Beef sandwiches are REALLY good. I hope you try the recipe.
Jane Megginson
I don't buy roasts usually, but I may. I do love the idea of the Chicago Italian Beef! I think getting that saute crockpot depends on how you mostly use it. But I agree, it may not be the most useful appliance. If you have a dutch oven, you can saute on the stove top and then put in the oven AND use it to bake incredible bread. Plus all the other great soups, etc.
Lois
You are going to love this Italian Beef, Jane.

There is one topping you might want to include that is a staple on true Chicago style Italian beef. That is giardiniera. It is a vegetable “salad” which can be mild to extra hot. Being from Chicago, I always got my beef drowned in an jus and with hot giardiniera. Much better than pepperoncinis, which are not available in the Chicago beef stands.
Lois
Good idea!
