In a small bowl combine the chopped thyme, rosemary, balsamic vinegar, olive oil, steak seasoning and crushed garlic.
Marinate the steak.
Cut the steak into 1 inch pieces and add the pieces of steak to a large zipper bag.
Pour 3/4 cup of the marinade over the steak and close the bag.
Toss the steak in the marinade until it’s fully coated, then place the marinating steak in the refrigerator.
Marinate for at least 4 hours, or overnight.
Boil and season the potatoes.
Once the steak has marinated, bring a large pot of water to boil on the stove.
Add the potatoes and boil for 15 minutes (or until barely fork tender).
Drain the potatoes and place them in a medium bowl.
Pour the remaining marinade over the potatoes and toss until coated.
Skewer the steak and potatoes.
Once the steak has marinated, remove it from the refrigerator.
Remove each piece of steak from the marinade and discard any additional marinade in the bag.
Skewer the cubes of steak with the seasoned potatoes.
Grill the skewers.
Heat a grill over medium-high heat.
Once the grill is heated to medium-high heat, between 400-450°F, add the skewers to the grill.
Grill for 4 minutes per side, for medium rare steak. Grill for 6 minutes per side, for medium steak.
Remove the skewers from the grill and place on a large cutting board.
Tent the skewers with a piece of foil and let rest for 5-10 minutes before serving.
You can replace the sirloin with filet mignon for a more tender and flavorful cut of meat. If using filet, instead of sirloin, you will only need to marinate the steak for 30 minutes, or up to 2 hours.
You can use metal or bamboo/wooden skewers. If using bamboo or wooden skewers, you will want to soak them in water for at least 30 minutes before adding the steak and potatoes. This prevents them from catching fire when placing them on a hot grill.

You can make this recipe in the oven if a grill is not available. To do so, preheat the broiler on your oven to high. Place a rack approximately 6 inches from the top of the oven. Place the skewers on an oven safe baking sheet and into the oven for 4 minutes for medium rare, 6 minutes for medium. Remove the skewers from the oven, flip and place back into the oven for 4 minutes, for medium rare, or 6 minutes for medium.
