Before you start
Before beginning the cooking process, ensure that you have your slow cooker clean and ready for use. No special prep is required for the beef other than removing it from any packaging and patting it dry if it feels excessively wet.
Prepare your measuring cup for the broth and have your two forks ready nearby, as they will be essential for the shredding stage later on. Having all ingredients measured and organized on the counter will make the assembly process seamless and quick.

- 2 lb beef chuck roast
- 4 oz diced green chiles
- 1 packet fajita seasoning
- 1 cup beef broth
- 1 cup shredded pepper jack cheese
Instructions
Assembling the Slow Cooker
- Assemble IngredientsPlace the raw beef chuck roast into the bottom of the slow cooker. Scatter the diced green chiles evenly over the meat. Sprinkle the fajita seasoning across the top of the beef and chiles, then pour the beef broth over everything. Cover the slow cooker with its lid.Look for The beef is fully submerged in the broth and seasoning mixture.Tip Ensure the beef is lying flat for even cooking throughout the process.
At this stage, the beef, chiles, seasoning, and broth should be layered neatly in the slow cooker insert. Everything should look uniform, with the seasoning distributed evenly over the meat to ensure consistent flavor development as the cooking time progresses.
Ensure the lid is seated firmly, as a tight seal is vital for maintaining the internal moisture and heat required for the slow cooking process to work effectively.
Cooking and Shredding
- Slow CookCook the beef on low heat for 8 hours or on high heat for 4 hours until the meat is fork-tender. Once cooked, remove the beef from the slow cooker and transfer it to a large bowl. Use two forks to shred the beef into thin, bite-sized strips.Look for The beef reaches an internal temperature of 145°F (63°C) and pulls apart easily with a fork.Safe temperature 145°F (63°C) internal temperature (steaks, chops and roasts)Tip Let the meat rest for at least 3 minutes before shredding to retain its natural juices.
The beef should be exceptionally tender, with the fibers separating easily when pulled with two forks. If the beef is still firm, continue cooking for an additional 30 minutes. The cooking liquid should have a rich, savory aroma, and the beef should be dark, indicating that it has absorbed the fajita seasoning and green chiles. This is the crucial point where the texture is established for the final dish.
Melting and Finishing
- Combine and FinishReturn the shredded beef to the slow cooker insert. Add the shredded pepper jack cheese to the warm beef. Stir the mixture thoroughly until the cheese is completely melted and the beef is well coated. Serve immediately as a filling for taquitos.Look for The cheese is fully melted and creates a creamy, cohesive texture with the shredded beef.Tip Stir in the cheese while the beef is still piping hot to ensure even melting without needing extra heat.
The final mixture should be creamy, with the melted pepper jack cheese thoroughly coating every strand of shredded beef. The filling should be cohesive, holding its shape well when scooped, which makes it perfect for filling tortillas. If the mixture appears too thick, you can stir in a small amount of the reserved cooking liquid until the desired consistency is achieved, ensuring it is ready for immediate use.
Common mistakes
A common mistake is attempting to shred the beef before it is fully tender. If the meat resists the fork, it simply needs more time to cook, as the collagen requires sufficient heat to break down into gelatin.
Another error is adding the cheese too early; always add the cheese only after the beef is shredded and returned to the slow cooker to prevent the cheese from separating or becoming oily from prolonged exposure to high heat.
How to tell it’s done
The beef is considered done when it reaches an internal temperature of 145°F (63°C) and pulls apart easily with a fork. It is important to let the meat rest for at least 3 minutes after removing it from the slow cooker before you begin the shredding process.
This resting period allows the juices to redistribute throughout the meat, ensuring that the final filling remains succulent rather than dry, even after it is tossed with the cheese.
- Steaks, chops and roasts: 145°F (63°C) in the thickest part, then a 3-minute rest
