First things first, what is barbacoa? Depending on where you are will depend on what type of meat and preparation. In some areas it’s goat, beef or pork. But in a nutshell, it’s slowly cooked meat. From the research I’ve done, the word barbacoa has translated to barbecue over time. Whether that refers to the spices used or preparation, it’s hard to tell. In modern Mexico, some may slowly cook it over an open fire or dug in a whole covered with a certain type of leaf. However, in my kitchen I use the slow cooker so I can set it and forget it.

The key to getting more flavor and texture with your beef barbacoa is to season the meat well with kosher salt and black pepper before searing it in a hot skillet. Then cooking the onions in the pan while scraping all the flavor-filled browned bits on the bottom of the skillet before adding it into your slow cooker.

The simplest way to serve beef barbacoa is to fill tortillas with the saucy, shredded beef and top with onions, cilantro and a squeeze lime juice. However you can’t go wrong with anyway you decide to serve it. I love it on nachos where the exposed ends of the barbacoa get crispy in the hot oven.

To Make This Slow Cooker Beef Barbacoa You Will Need:

  • beef chuck roast
  • salt and pepper
  • extra light olive oil or avocado oil
  • sweet onions
  • brown sugar

season chuck roast

First preheat a large stainless skillet or dutch oven over medium-high heat. Season all the sides of 5 to 6 pounds beef chuck roast with kosher salt and freshly ground black pepper. Because my grocery store doesn’t carry any chuck roast over 2-1/2 pounds, I had purchased two.
