Cut beef into 4 large chunks and pat dry with paper towels. Season the beef on all sides with generous amounts of salt and pepper. Heat olive oil in a large frying pan over medium heat. Once hot, add in the steak and sear for ~2-5 minutes on each side or until they get a nice sear.
3 lb. Chuck steak, boneless, 1 Tbsp. salt, 1 Tbsp. pepper, 2 Tbsp. olive oil
Transfer the meat to a crockpot and pour in the beef broth, lime juice, beef taco seasoning and onions. Gently stir to combine.
2 cups beef broth, 1/4 cup lime juice (juice from 1 lime), 1 white onion, sliced, 1 Tbsp. chipotle powder, 1 Tbsp. paprika, 2 tsp. chili powder, 1 tsp. garlic powder, 1 tsp. cumin
Cook on low for a minimum of 8 hours, I usually like to let it cook for 10 hours. (Low and slow is key for tender beef!) Shred and add the beef back into the juices in the slow cooker.
Assemble the tacos with your favorite taco toppings.
