If you love a classic Crockpot French dip or roast beef sandwich, you’re going to love this bold twist. I start by roasting jalapeños, onions, and garlic in the oven, then add them to the crockpot with a chuck roast and rich au jus. As it slow cooks all day, the flavors meld into tender, spicy, and downright decadent Jalapeno Beef Sandwiches. For the ultimate experience, use the flavorful drippings as a dipping sauce to take these sandwiches to the next level.
Ingredients Needed:
This recipe starts with a hearty chuck roast, slow-cooked to perfection in a rich au jus for incredible flavor. Roasted jalapeños, onions, and garlic add a smoky, slightly spicy kick that sets these sandwiches apart. {The full recipe is in the recipe card below the images}
How to make Jalapeno Beef Sandwiches:
- Add the chuck roast to the slow cooker.
- To a sheet pan, add the vegetables.
- Roast under the broiler in the oven until charred. Add that on top of the roast.
- Cook on LOW for 9 hours.
- Shred the meat with two forks, right in the slow cooker. Remove the caps from the peppers and shred those into the meat as well. Strain and degrease the drippings to make an “au jus”.
Variations
- Use poblano peppers instead of jalapenos for a different flavor.
- Short on time? You can forgo broiling the vegetables and place them straight into the slow cooker.
- Add barbecue sauce for spicy barbecue sandwiches.
- Add chipotle peppers in adobo for a smokey flavor.
My Serving Suggestions
- To make into “french dips”. Remove the meat onto a plate and cover with foil. You can strain the drippings through a mesh strainer if desired and add back to the slow cooker. Degrease the drippings (which are the “au jus”) by placing a paper towel over them then, removing. Add cheese to the hoagie rolls and add jalapenos and onions if desired.
- You can also serve the shredded jalapeno beef on slider buns instead.
- Instead of sandwiches, you can do tacos, burritos or nachos (great ideas for leftovers as well).
