• Cutting board
• Measuring cups and spoons
• Large mixing bowl
• Two forks for shredding

INGREDIENTS

For the beef:

• 3 lbs (1.4 kg) beef chuck roast, cut into large chunks
• 1 cup (240ml) beef bone broth
• 1 large white onion, diced
• 4 garlic cloves, minced
• 2-3 chipotle peppers in adobo sauce, chopped
• 2 tablespoons adobo sauce from the can
• Juice of 2 fresh limes (about ¼ cup/60ml)

Spice blend:

• 2 tablespoons ground cumin
• 1 tablespoon Mexican oregano (or regular oregano)
• 1 tablespoon smoked paprika
• 2 bay leaves
• ¼ teaspoon ground cloves
• ¼ teaspoon cinnamon
• 2 teaspoons salt
• 1 teaspoon black pepper

For serving (optional):

• Fresh cilantro, chopped
• Sliced radishes
• Pickled red onions
• Butter lettuce cups
• Cauliflower rice
• Sliced jalapeños
• Extra lime wedges

METHOD

1. Prep your beef

Cut the chuck roast into 3-4 inch chunks, trimming any excess fat. Pat completely dry with paper towels. Season generously with salt and pepper.

2. Brown the beef (optional but recommended)

Heat a large skillet over medium-high heat. Brown beef chunks on all sides, about 2-3 minutes per side. This step adds incredible depth of flavor.

3. Make your barbacoa sauce

In a mixing bowl, combine chopped chipotles, adobo sauce, lime juice, beef broth, cumin, oregano, paprika, cloves, and cinnamon. Whisk until well combined. Taste and adjust spice level – add more chipotles for heat.

4. Assemble in slow cooker

Place browned beef chunks in your slow cooker. Add diced onions and minced garlic. Pour the barbacoa sauce over everything. Toss to coat evenly. Nestle bay leaves on top.

5. Cook low and slow

Set slow cooker to low for 6-8 hours or high for 4-5 hours. Don’t lift the lid – you’ll lose precious heat and moisture.

6. Check for doneness

After 6 hours on low, test with a fork. The beef should shred easily and feel tender throughout. Internal temperature should reach 200°F (93°C) for perfect shreddability.

7. Shred and finish

Remove bay leaves. Using two forks, shred the beef right in the slow cooker. Let it sit in the juices for 10 minutes to absorb all those flavors. Taste and adjust salt, lime juice, or spice as needed.

CRUCIAL TIPS

• Don’t skip the browning step – it creates a flavor foundation that makes all the difference
• Use chuck roast, not lean cuts – the fat content is essential for tender, juicy barbacoa
• Resist opening the slow cooker – every peek adds 15-30 minutes to cooking time
• Start checking at 6 hours on low – overcooked barbacoa becomes dry and stringy
• Save some cooking liquid – perfect for reheating leftovers without drying out

Storage:

Refrigerate in airtight containers for up to 5 days. Freeze in portion-sized bags for up to 3 months. Always store with some of the cooking juices.

Scaling tips:

This recipe doubles perfectly for meal prep. Your slow cooker should be at least half full for even cooking. Adjust liquid proportionally – more beef needs more broth.

Common mistakes to avoid:

• Using too little liquid results in burnt, dry meat
• Cooking on high for too long makes tough, stringy beef
• Forgetting to remove bay leaves before serving
• Not tasting and adjusting seasoning at the end

Variations:

• Beef cheek barbacoa: Swap chuck roast for beef cheeks for ultra-traditional flavor
• Milder version: Use just 1 chipotle pepper and add smoked paprika for smokiness without heat
• Extra smoky: Add ½ teaspoon liquid smoke to the sauce
• Citrus twist: Add orange zest along with lime juice for complexity

This slow cooker keto beef barbacoa delivers restaurant-quality results with minimal effort. The meat becomes so tender it practically shreds itself, while the sauce reduces to a rich, smoky concentrate that coats every strand of beef.

Serve it over cauliflower rice for a complete keto meal, stuff it in butter lettuce cups for fresh tacos, or eat it straight from the bowl with a fork. Each serving contains just 2-3 net carbs while packing 35+ grams of protein.

The best part?
Your house will smell absolutely incredible for hours. Don’t be surprised when neighbors start asking what you’re cooking.
