🌶 Ingredient notes

• Beef - A chuck roast is a great cut of beef for slow cooking. It has even fat marbling and will break down well for shredding. About 50% of the weight is lost in cooking, so a 4 pound roast will yield approximately 3 tacos per person for about 8-10 people.
• Chipotle Peppers - Chipotle peppers are ripened jalapeños that have been smoked and dried. They also can be found canned in adobo sauce and add a smoky, spicy flavor to the beef. For less spice, only use 1 or 2 peppers and for more heat, use 3 or 4. The chipotle peppers can also be omitted, if desired.
• Toppings - The traditional toppings for barbacoa tacos are diced onions and chopped cilantro. I like serving these tacos with fresh lime wedges to squeeze on top and a bit of cotija cheese. Alternative toppings ideas include salsa verde, hot sauce, sliced avocado, pico de gallo or beans.

🔪 Step by step instructions

First, add the chuck roast to the slow cooker and then top with the remaining ingredients, minus the accompaniments.

Cook on high for 3 hours and then reduce the heat to low for 2 hours. Remove the beef and shred with two forks.

Add the shredded beef back to the slow cooker and mix with the juices. Cook on low for 30-60 minutes and then serve on corn tortillas with the accompaniments.

⭐ Expert tips

• Buy a chuck roast that has even marbling for the best flavor and ease of shredding.
• Make sure to stir up the shredded beef with the spices and juices after putting it back in the slow cooker so that it evenly flavors the meat.

🥘 Alternative cooking methods

Oven - Place the chuck roast in a large cast iron skillet or a dutch oven. Add the remaining ingredients, minus the accompaniments, on top of the roast. Cover with foil or a lid and cook in the oven at 300˚ for 3-4 hours until tender. Remove the roast from the dish, shred and add back to the juices to cook for an additional 30 minutes in the oven, covered.

🥡 Storage suggestions

This barbacoa beef will keep in an airtight container in the refrigerator for 3-5 days and in the freezer for up to 3 months. Frozen beef should be defrosted in the refrigerator and can be heated up in a skillet on the stovetop over medium heat with a little bit of beef broth or in a microwave.
