A Chicago beef sandwich is a local delicacy—a beautiful fusion of savory and spicy. If you’ve been lucky enough to have one, you know exactly what I’m talking about. But let’s be real—an au jus–dipped sandwich doesn’t exactly scream “weekly meal prep.” So, we’re swapping the bread for rice and turning it into a Chicago beef bowl, complete with savory au jus and spicy homemade giardiniera.
Traditional giardiniera is usually made with a brine of olive oil and vinegar. But through testing, I found that the oil isn’t necessary to make a delicious final product—and hey, bonus points for lowering the fat content. The vinegar still does the heavy lifting and carries all that spicy goodness. The best part? While classic giardiniera takes 2–4 days to make, this quick-pickled spicy version takes just 10 minutes.
For this recipe, we’re using a whole sirloin roast. You can usually find these at your local restaurant supply store, and they’re a great way to get a lot of beef for a good price. If you’ve never butchered your own meat before, don’t stress. It’s a super simple process and can save you a ton of money. As a bonus, you’ll end up with an entire picanha—one of the best cuts on the cow. It’ll cost you an arm and a leg at a butcher shop, but if you do it yourself, it’s a fraction of the price.
