It's easy to make THE BEST sirloin steak marinade with just a few simple ingredients. Quickly whisk the marinade ingredients together, marinate the steak, then toss it on the grill for the best flavor!
Combine the balsamic vinegar, low-sodium soy sauce, olive oil, Worcestershire sauce, honey, Italian seasoning and dried mustard in a gallon size zipper bag or large bowl.
Add the steaks and marinade for 20 minutes, or up to 8 hours.
Heat a grill over medium high heat, between 350-400 degrees Fahrenheit. Wait until the grill is hot before adding the steaks, to give them perfect sear marks.
Remove the steaks from the marinade and discard the marinade. Add the steaks to a hot grill.
For a perfect medium rare steak, grill a 1 inch thick steak for 4-5 minutes per side. For a steak that is 1 1/2 inches thick, add 1-2 minutes to the cooking time per side.
Insert an instant read thermometer into the steak. Remove the steak once it reads 130°F for a medium rare steak. For a medium steak, wait until it reaches 140°F and for a medium well steak, wait until it reaches 150°F.
Remove the steak from the grill and let it rest for 5-10 minutes. This ensures that the juices redistribute throughout the steak, leaving you with the most juicy steak possible!
Sprinkle coarse kosher salt or sea salt flakes over the steak and optionally garnish with fresh chopped parsley before serving.
Notes
Remember that a steaks internal temperature will rise approximately 5 degrees after you remove it from the grill and let it rest. Be sure to take this into consideration when checking the temperature before removing the steaks from the grill.
This recipe can be used to marinate steaks other than a top sirloin. Use it to marinate any of these cuts of steak:
Top Sirloin
Ribeye
New York Strip
Flank Steak
Skirt Steak
More tender cuts of steak, like the sirloin, ribeye and new york strip should marinade for 20 minutes, up to 2 hours.
Tougher cuts, like a flank or strip steak should marinate for 4-8 hours.
I do not recommend marinating for more than 8 hours. After then, the acidity of the marinade will start to break down the proteins and can cause the steak to become mushy.
Coconut aminos can be substituted for soy sauce to make the marinade soy-free and gluten-free. Coconut aminos are much lower in sodium than soy sauce, so I do recommend adding 1/2 teaspoon salt to the marinade if you replace the soy sauce with coconut aminos.
