Slow Cooker Beef Sandwiches

My husband absolutely loves beef and could practically live off just steak and potatoes everyday, if I let him. When we are planning to go out to dinner, his first choice is always a steakhouse or something similar. If I overrule him and we end up somewhere that’s not a steakhouse, I can almost guarantee you that he will order the only steak on the menu… or the only dish that has steak in it.

Browsing through my recipe posts, however, will show you that I do not cook much beef. Yeah, there are a couple beef recipes (and I plan on adding more just for him) but for the most part I stick to what I know… Breakfast food – which he eats none of, Chicken, and Desserts.

Now, he, of course, doesn’t mind that I have begun to do all the cooking and he still will eat just about everything that I put in front of him. When he cooks, it is usually steak and a side of veggies and unlike him, I cannot live off of beef alone. So yes, when I cook there are days that I feel bad about cooking chicken for the hundredth time and thus I give into his love of all things beef.

That is exactly what happened with these amazing sandwiches. See, we were heading to Chicago for the day and we usually stop somewhere on the way to grab a lunch. He was choosing the restaurant and came up with Portillo’s. Never been there, never heard of it. It’s an Italian beef fast food type restaurant. Great… more beef. Ok, I’ll try it.

I was very hesitant to try this Italian beef restaurant because the last time he took us to an Italian beef place it didn’t turn out well. There were 5 of us that ate that day and we all ended up with food poisoning. Yeah… see my hesitation now?

Fortunately, Portillo’s turned out to be amazing and we have since eaten there on just about every trip we make back to Chicago. We make the trip quite frequently but not frequent enough for the hubby to get his Italian beef fix.

So recently I decided to try and cook up my own version of an Italian beef. I cooked my meat low and slow to make sure that it was super tender and there were enough juice for him to dunk his sandwich in, just like he gets at Portillo’s. Then topped everything with shredded provolone cheese and hot giardiniera.

The hubby thoroughly enjoyed the sandwiches and has asked me to make them more than once since. So dig right in and enjoy this little twist on a classic beef sandwich.

  1. Love the sound of this, my idea of dream food, slow cooked beef is just awesome… Any chance you can expand on what giardiniera is a little more, not something I have come across here in Europe, well certainly not by that name anyway.

    1. Giardiniera is basically a blend of peppers, cauliflower, celery, and carrots and then marinated in oil and white-vinegar with a blend of spices. You can make it hot and spicy (which is how I like it) with your pepper and spice blend or make a mild version instead. It’s super amazing on beef sandwiches!

    1. Bahahaha! My husband TOLD ME he was Italian when we first met. He is not anywhere close to Italian descent – he’s Dutch and Trinidadian. But he definitely loves his Italian beef sandwiches.
