Ingredients
- 3-4 lbs. beef chuck roast
- 1 tsp. onion powder
- 1 tsp. garlic powder
- 1/4 tsp. black pepper
- 1 oz. packet Au Jus Gravy
- 3-4 jalapenos
- 1 white onion, peeled and cut into eighths
- 6 garlic cloves, left whole
- 1 cup water
- Hoagie rolls
- Cheddar or Monterey Jack cheese
- Additional sliced jalapeno, if desired
- Sliced white onion for topping
Instructions
- Step 1: Place the beef chuck roast into the slow cooker. Sprinkle the onion powder, garlic powder, black pepper, and Au Jus Gravy packet evenly over the meat.
- Step 2: Preheat your oven to broil. Arrange the jalapenos, onion pieces, and whole garlic cloves on a baking sheet.
- Step 3: Broil the vegetables until they begin to brown and char slightly, which enhances their flavor.
- Step 4: Transfer the roasted vegetables to the slow cooker on top of the beef. Pour in one cup of water.
- Step 5: Cover the slow cooker and cook on LOW for 9 hours, or until the meat is tender enough to shred easily.
- Step 6: Remove the beef from the slow cooker and shred it with two forks, discarding any fatty pieces. Remove the tops from the jalapenos and shred them into smaller pieces as well.
- Step 7: Return the shredded beef and jalapenos to the slow cooker, mixing them into the cooking juices.
- Step 8: To reduce grease, lay paper towels over the juices in the slow cooker and remove once absorbed.
- Step 9: Toast the hoagie rolls, then pile on the shredded beef mixture. Top with slices of cheddar or Monterey Jack cheese. For melted cheese, place the assembled sandwiches under the broiler briefly.
- Step 10: Serve the sandwiches with warmed Au Jus gravy on the side for dipping, along with extra sliced jalapenos and onion if you like.
Tips & Variations
- For milder sandwiches, remove the jalapeno seeds before roasting to reduce heat.
- Substitute beef chuck roast with brisket for a richer flavor.
- Add a splash of Worcestershire sauce to the slow cooker for an extra depth of taste.
- Use pepper jack cheese to add a subtle spicy kick to the sandwich.
- Serve on toasted brioche buns for a slightly sweeter contrast to the spicy beef.
Storage
Store leftover shredded beef in an airtight container in the refrigerator for up to 3 days. Reheat gently in a skillet or microwave, adding a splash of water or au jus to keep the meat moist. The assembled sandwiches are best eaten fresh for the best texture of the bread and melted cheese.

FAQs
Can I use a different type of meat?
Yes, brisket or a shoulder roast are great alternatives that also become tender with slow cooking.
How spicy are these sandwiches?
The spice level depends on the amount of jalapenos used and whether you include the seeds. Roasting mellows the heat but the jalapenos still add a noticeable kick.
