  • Ninja Foodi Indoor Grill


  • lbs London Broil
  • ¼ cup red wine vinegar
  • 1 Tbsp olive oil
  • Tbsp spicy mustard
  • 2 cloves garlic minced
  • 1 Tbsp Worcestershire sauce
  • 1-2 tsp rosemary fresh and chopped or 1/2 tsp dried rosemary
  • 1 tsp sea salt
  • 1 tsp onion powder
  • 1 tsp dried thyme leaves or 1 Tbsp of fresh thyme
  • ½ tsp black pepper


  • Trim up the steak if there is any visible fat. Tenderize each side with a meat tenderizer.
  • Mince the garlic cloves and finely chop the rosemary if using fresh. Combine all the marinade ingredients into a large plastic, sealable bag. Or use a shallow container with a lid. Add the steak and seal the bag. Mix the marinade all around so the ingredients combine with each other. Then squeeze the air out of the bag and refrigerate for 2-4 hours.
  • Remove the steak from the fridge, leave it in the bag and let it sit at room temp for 30 minutes.
  • Remove the steak from the bag and blot off the marinade. Preheat the indoor grill on max grill. When it says "ADD FOOD" lay the steak on the grill surface and press the steak down onto the grill surface.
  • Grill on max grill for 4 minutes and then flip. Grill on max grill another 2-4 minutes for medium rare. Remove from grill and let the steak rest for 5-10 minutes.
  • Slice thinly across the grain. Serve & Enjoy!
