Grilled top sirloin steak gets a quick balsamic marinade before hitting an outdoor grill or stovetop grill pan. The marinade adds garlic, Dijon, basil, and tangy flavor while still letting the beef flavor come through. Use an instant-read thermometer and let the steak rest before slicing for the best texture.

Instructions

In a large bowl, whisk together the Dijon mustard, balsamic vinegar, olive oil, garlic, basil, salt, and pepper.
1 tbsp Dijon mustard, ½ cup balsamic vinegar, ¼ cup olive oil, 3 cloves garlic, 2 tbsp Basil, 1 tsp salt, ½ tsp black pepper
Add the sirloin steaks to the bowl of balsamic marinade and toss to coat.

Cover the bowl and refrigerate for at least 30 minutes, or up to overnight.
Preheat a grill pan or grill to medium-high heat.

Medium-high heat is about 425°F to 450°F. On an electric outdoor grill, the 450°F sear setting works well for top sirloin because it gives strong grill marks while cooking the steak quickly.

Remove the steak from the marinade and grill for 3 to 5 minutes per side, or until cooked to desired doneness.
Use an instant read thermometer to make sure remove your grilled sirloin steaks from the heat when they reach your desired doneness temperature:
Rare: 120-125℉
Medium-rare: 130-135℉
Medium: 140-145℉
Let the steak rest for 5 minutes before slicing. This will allow the juices to redistribute throughout the meat, resulting in a more tender and juicy steak.

Notes

If you don't have a grill pan, you can sear in a pre heated skillet, or grill the steaks on a regular grill. Just be sure to preheat the grill to medium-high heat and cook the steak for 5-6 minutes per side, or until cooked to desired doneness.
Let the steak rest for 5 minutes before slicing. This will allow the juices to redistribute throughout the meat, resulting in a more tender and juicy steak.
To ensure that your sirloin steaks are grilled to perfection, use a meat thermometer to check the internal temperature.
