Slow-Cooker Chipotle Beef Barbacoa

Ingredients

• 3.5–4 lbs grass-fed beef chuck roast (trimmed of excess exterior fat, cut into 3-inch chunks)
• 1 tbsp avocado oil or rendered beef tallow (for searing)
• 1 medium white onion, roughly chopped
• 6 cloves garlic, peeled
• 0.75 cup organic beef bone broth (or filtered water)
• 0.33 cup fresh lime juice (approx. 3 fresh limes)
• 0.25 cup raw unfiltered apple cider vinegar
• 2 tbsp tomato paste (100% organic, no added sugar)
• 2 tsp pure ground chipotle chili powder (or 2 whole dried chipotle chiles, stemmed)
• 1 tbsp ground cumin
• 1 tbsp dried Mexican oregano
• 1 tsp ground cloves
• 1.5 tbsp coarse Celtic sea salt
• 1 tsp freshly cracked black pepper
• 3 whole dried bay leaves

Step-by-Step Instructions

1. Blend the Braising Sauce: In a high-speed blender, combine the chopped white onion, garlic cloves, beef bone broth, fresh lime juice, apple cider vinegar, tomato paste, ground chipotle powder, cumin, Mexican oregano, ground cloves, sea salt, and black pepper. Blend on high for 45 seconds until smooth and emulsified.
2. Sear the Beef (Optional but Recommended): Heat avocado oil in a large cast-iron skillet over high heat. Sear the beef chunks in batches for 2 to 3 minutes per side until deeply browned. Transfer seared beef into the slow cooker basin.
3. Combine in Slow Cooker: Pour the blended chipotle marinade entirely over the beef chunks. Tuck the three dried bay leaves deep into the liquid.
4. Slow Cook: Cover with the slow cooker lid and cook on LOW for 7 to 8 hours (or on HIGH for 4 to 5 hours) until the meat is fork-tender and shreds effortlessly. (Instant Pot alternative: Pressure cook on High for 65 minutes with natural pressure release.)
5. Shred & Soak: Remove the bay leaves. Use two forks to shred the beef directly inside the slow cooker basin, allowing the tender meat strands to absorb the rich, concentrated braising broth.
6. Serve: Serve hot over cilantro-lime cauliflower rice, inside crisp romaine lettuce cups, or wrapped in grain-free cassava tortillas with sliced avocado, pickled red onions, and fresh cilantro.

Nutritional Breakdown (Per Serving)

Chef's Paleo Nutritional Science

Slow-cooking beef chuck roast breaks down tough intramuscular collagen fibers into gelatin, supplying substantial amounts of glycine, proline, and hydroxyproline that soothe the intestinal mucosal barrier and support joint integrity. The combination of acidic apple cider vinegar and fresh lime juice lowers the pH during cooking, facilitating optimal mineral extraction from the meat and bone broth.
