This Chipotle garlic guajillo steak copycat is easy to make at home! With tender broiled flank steak marinated in a bright, zesty puree made from smoky chilies, garlic, fresh cilantro, and lime.
Hydrate the chilies. Place the chilies in a saucepan and cover with water. Bring the water to a boil and then turn the heat to medium-low. Allow the chilies to simmer for 30 minutes. Drain the chilies, reserving ½ cup cooking liquid.
Make the marinade. Combine the reserved cooking liquid from the chilies, the chilies (stems removed), garlic, lime juice, olive oil, and cilantro in a blender. Blend until smooth.
Marinate the steak. Place the steak in a freezer bag. Pour the marinade over it and seal the bag. Massage the marinade into the meat through the bag. Allow the steak to marinate in the fridge for 1 hour and 45 minutes, then remove it from the fridge and let it sit on the counter for 15 minutes.
Broil. Arrange an oven rack in the middle of the oven and set the oven to broil. Line a baking sheet with aluminum foil and place the steak on the baking sheet. Season it on both sides with salt. Broil for 4 minutes, flip, and broil for an additional 4 minutes or until a meat thermometer inserted into the thickest part of the steak reads 135°F (for medium-rare).
Rest. Remove the steak from the oven and allow it to rest for 5-10 minutes before slicing and serving.
