Directions: How to Make Slow Cooker Cowboy Sandwiches
Step 1: Prep and Load the Slow Cooker
Add the beef chunks, diced onion, bell pepper, pinto beans, diced tomatoes (with juices), garlic, and all seasonings (smoked paprika, chili powder, cumin, salt, and pepper) into your slow cooker. Pour the barbecue sauce and Worcestershire sauce over the top. Give everything a good stir to combine.
Step 2: Set and Forget
Cover and cook on LOW for 7-8 hours, or on HIGH for 4-5 hours, until the beef is ultra-tender and shreds easily with two forks.
Step 3: Shred and Finish
Remove the beef from the slow cooker, shred it using two forks, and return it to the sauce. Stir in the shredded cheddar cheese until melty and well-mixed. Let it sit for 5 minutes for flavors to meld.
Step 4: Assemble the Cowboy Sandwiches
Spoon a generous portion of the cowboy beef mixture onto each sandwich bun. Top with extra cheese or jalapeños, if desired. Serve hot and enjoy every flavorful bite!
Notes for Perfect Slow Cooker Cowboy Sandwiches
- For max flavor, sear your beef chunks in a hot skillet before adding them to the slow cooker (learn more about browning meat).
- Swap cheddar for pepper jack for a spicier kick.
- Low-sugar or homemade barbecue sauce makes these sandwiches lighter (try this recipe).
