Slow Cooker Beef Barbacoa with chipotles in smoked adobo, beef stock, beer, tomato paste, brown sugar, garlic, cilantro, & spices. Fall-apart tender!
Gently pour the beer and beef stock into the slow cooker without rinsing the paste off the roast. Close the lid and let the roast cook for 7-8 hours on low. (Chuck roast may cook faster - check at 5-6 hours.)
Be careful handling the chipotles in Adobe Sauce - they can stain dishtowels, cutting boards, clothing etc, very easily.
You can substitute beef stock or water for the beer if desired. Remember, the more flavor you put it, the more flavor you'll get out.
