Ingredients You’ll Need

• 3–4 lb beef chuck roast, seared on all sides

• 1 large onion, sliced

• 1 (14.5 oz) can fire-roasted tomatoes

• 1 (4 oz) can diced green chilies (choose mild or hot)

• 1 cup beef broth (add more if needed to cover about half the roast)

• 2 tsp salt (adjust to taste)

• 1 tsp black pepper

• 2 tsp garlic powder

• 2 tsp smoked paprika

• 2 tsp ground cumin

• ½ tsp cayenne pepper (add more if you like heat)

• 1 tsp dried oregano

• Juice of 1 lime (added at the end)

Step-by-Step Instructions

1. Sear the Beef

Start by heating a little oil in a skillet over medium-high heat. Sear the chuck roast on all sides until it develops a golden-brown crust. This step adds extra flavor but is optional if you’re short on time. Place the roast in your crockpot.

2. Add Vegetables and Liquids

Add the sliced onions, fire-roasted tomatoes, diced green chilies, and beef broth around the roast in the crockpot. The broth should cover about half of the roast to keep it moist during cooking.

3. Season Generously

Sprinkle the salt, black pepper, garlic powder, smoked paprika, cumin, cayenne pepper, and oregano evenly over the roast and vegetables. These spices create the signature smoky and slightly spicy flavor that makes these tacos stand out.

4. Slow Cook the Beef

Cover the crockpot and cook on low for 8 to 10 hours. This slow cooking process breaks down the beef, making it tender enough to shred easily with a fork. If you’re short on time, cook on high for 4 to 5 hours, but low and slow is best for maximum flavor and tenderness.

5. Shred and Finish

Once the beef is tender, remove it from the crockpot and shred it using two forks. Return the shredded beef to the crockpot and stir in the fresh lime juice. Taste and adjust seasoning if needed.

6. Assemble Your Tacos

Warm your tortillas and spoon the shredded beef onto each one. Add your favorite toppings like diced onions, cilantro, avocado slices, cotija cheese, or salsa. Serve immediately and enjoy!

Tips for Perfect Crockpot Mexican Beef Tacos

• Searing the beef adds depth of flavor but skip it if you’re in a hurry. The slow cooker will still do a great job.

• If you like your tacos extra spicy, increase the cayenne pepper or add a few dashes of hot sauce when serving.

• Use fire-roasted tomatoes for a smoky flavor that complements the spices perfectly.

• Leftovers work great for taco salads, burrito bowls, or simply served over rice with avocado.

• For a milder version, use mild green chilies and reduce the cayenne pepper.
