Ingredients You'll Need (and Why)
Chuck roast or beef brisket: These cuts have plenty of internal fat and connective tissue that break down during long, slow cooking, resulting in ultra-tender meat.
Smoked paprika: Adds a distinct, wood-fire smoky depth to the spice rub that mimics authentic outdoor cooking.
Tomato paste: Acts as a thickener for the cooking liquid while adding concentrated umami flavor to the braising sauce.
Lime juice: Provides essential acidity that cuts through the rich, savory beef and balances the heavy spices.
How to Make It
The Spice Rub & Braising Liquid
Building great flavor starts with a balanced dry rub. Massaging the spices directly into the beef ensures every bite is seasoned. Whisking the broth, tomato paste, lime juice, and garlic together creates a rich liquid base that keeps the meat moist as it gently simmers all day.
The Slow Cook & Rest
Low and slow is the secret to breaking down tough cuts of beef. Letting the meat cook uninterrupted allows the connective tissues to melt into gelatin. Once tender, returning the shredded beef to the warm juices ensures the meat stays succulent and deeply flavorful rather than drying out.
Success Tips
- Make sure your chuck roast is trimmed of any overly thick, hard fat caps, leaving just enough marbling for moisture.
- Test for doneness by seeing if the beef pulls apart effortlessly with the gentle pull of a fork.
- Always warm your tortillas before assembling so they are pliable and won't crack or tear when loaded with meat.
Variations
- Swap the chuck roast for boneless lamb shoulder if you prefer lamb tacos.
Storage & Make-Ahead
Fridge: Store leftover shredded beef in an airtight container with its juices for up to 3 to 4 days.

FAQ
Can I make this recipe on HIGH if I am short on time?
Yes, you can cook the beef on HIGH for 4 to 5 hours. However, cooking on LOW for 8 hours yields the most tender texture.
Do I need to sear the beef before putting it in the slow cooker?
No searing is required for this recipe! Simply rub the spices on the raw beef, add your liquids, and let the slow cooker do the work.
How do I prevent the meat from getting dry?
Always return the shredded beef to the leftover juices in the slow cooker for at least 10 minutes before serving so it can reabsorb moisture.
