Instructions:
- Prepare the Flank Steak: Begin by generously seasoning both sides of the flank steak with salt. This will help to enhance the flavor of the meat as it cooks.
- Prepare the Chipotle Sauce: In a blender or food processor, combine the chipotle chiles in adobo sauce with the beef stock. Blend until smooth and well combined.
- Layer the Ingredients in the Slow Cooker: Place the seasoned flank steak in the bottom of a 6-quart slow cooker. Pour the chipotle sauce over the steak, ensuring that it is evenly distributed.
- Cook Low and Slow: Cover the slow cooker and cook on low heat for 8 hours, or until the beef is tender and easily shreds with a fork. The long cooking time allows the flavors to meld together, resulting in a rich and aromatic dish.
- Thicken the Sauce: Once the beef is cooked, remove it from the slow cooker and transfer it to a cutting board. In a small bowl, mix the cornstarch with a bit of water to create a slurry. Stir the slurry into the sauce remaining in the slow cooker to thicken it slightly.
- Serve and Enjoy: Slice the cooked flank steak against the grain and serve it with the thickened chipotle sauce poured over the top. Garnish with fresh cilantro or sliced green onions, if desired.
