Ingredients

For the flank steak

  • 1.5 - 2 lb flank steak
  • kosher salt and black pepper to taste
  • ½ teaspoon garlic powder

For the grilled corn salsa

  • 4 ears corn shucked
  • 1 tbs olive oil
  • 1 pint cherry tomatoes halved
  • 1 jalapeño ribs and seeds removed, minced
  • 3 tbs cilantro chopped
  • 1 lime juiced
  • kosher salt and black pepper to taste

Instructions

To make the flank steak

  • Preheat the sous vide water bath to 135 degrees F for a flank steak cooked to medium (see notes).
  • Season the flank steak on both sides.
  • Vacuum seal the flank steak. Add it to the water bath and cook for 2-3 hours.
  • Once cooked, remove it from the water bath and the vacuum seal bag. Pat both sides of the steak dry with paper towels. Re-season, if desired.
  • Sear the steak on both sides until browned (see notes).
  • Allow the steak to rest for 5 minutes before slicing.

To make the grilled corn salsa

  • Lightly brush the ears of corn with olive oil. Grill, rotating periodically, until lightly charred.
  • Cut the corn kernels from the cob. Add to a medium-sized bowl.
  • Add the remaining ingredients to the bowl and toss to combine.
  • Serve over the sliced flank steak.

Notes

  • Use the following temperatures to arrive at different levels of doneness: 123 degrees F for rare; 129 degrees F for medium-rare; 135 degrees F for medium; 143 degrees F for medium-well
  • You can sear the steak over a charcoal or gas grill or in a screaming hot pan (cast iron preferred)
