One of your local mirrors listed in /etc/apt/sources.list.d/*.list or /etc/apt/sources.list probably uses https (not a very common scenario for package mirrors), in which case you need the package mentioned above (apt versions below 0.9.15.3 fell back to plain http, if https was unavailable).
Line a broiler pan with aluminum foil, add the top, and spray the top with nonstick cooking spray. Broil the steak 4 to 6 minutes per side: Remove the steak from the marinade, shake off any excess, and place it in the middle of the broiler pan. Slide it directly under the broil. Cook for 4 to 6 minutes, flip it over, and broil for another 4 to 6 minutes (8 to 12 minutes total). Check the steak for doneness: The steak is done when the edges are charred and crispy, and you see some nicely dark searing on the top.
The Best Way to Cook Flank Steak. You can grill flank steak, cook it in a skillet on the stovetop, or even cut it up for a stir-fry, but my choice for everyday cooking is under the broiler. The broiler is basically an upside-down grill that blasts the steak with direct heat.arinate for 1 hour or up to 24 hours: Cover the dish and place the steak in the fridge for at least 1 hour or up to 24 hours. Flip the steak occasionally if you happen to think about it. Heat the broiler and prepare the pan: Set your broiler to its highest setting (or simply turn it on if it doesn't have settings).
