Ingredients
  

Beef chuck roast
  • 3 lb beef chuck roast Use chuck roast for best shred-when-cooked tenderness.
Cooking liquid
  • 1 cup beef broth
  • 1 packet taco seasoning
  • 0.5 white onion Slice into thin rings so it softens during the long cook.
  • 4 garlic Minced for even flavor throughout the beef.
  • 0.25 tsp salt and pepper Season to taste; add a pinch early and adjust after shredding if needed.
Taco toppings
  • 1 warm tortillas Warm right before serving so they stay flexible.
  • lettuce Fresh, shredded or chopped.
  • tomato Diced or chopped.
  • cheese Shredded or crumbled.
  • sour cream
  • salsa

Equipment

  • 1 slow cooker

Method
 

Slow-cook the beef
  1. Place the beef chuck roast in a slow cooker and sprinkle with taco seasoning.
  2. Add beef broth, sliced white onion, and minced garlic to the slow cooker.
  3. Cover and cook on low for 6 hours until the beef is extremely tender and shreds easily with a fork, checking visually for heavy softness and pull-apart texture near the end.
Shred and combine
  1. Remove the beef to a cutting board and shred into bite-sized pieces.
  2. Return the shredded beef to the slow cooker and stir to combine with the cooking liquid.
  3. Rest the shredded beef in the slow cooker for 10 minutes so the juices cling and the texture stays moist.
Assemble and serve
  1. Warm the tortillas and fill them with shredded beef.
  2. Top with lettuce, tomato, cheese, sour cream, and salsa as desired, arranging evenly for each taco.
  3. Serve with the warm cooking liquid on the side for drizzling over tacos.

Notes

Pro tip: For the easiest shredding, check at 5 1/2 hours—when the beef falls apart with a fork, it’s ready. Refrigerate leftovers in an airtight container for up to 4 days; rewarm gently on the stovetop or in the slow cooker. Freezing is yes—freeze beef (without fresh toppings) up to 2 months and thaw in the fridge. Dietary swap: Use a low-sodium taco seasoning and choose low-sodium beef broth to reduce sodium while keeping the same slow-cooker method.
