Tender, marinated grilled flank steak with tomato olive relish is not only delicious but so pretty too! A showstopper at your next meal or dinner party for sure.

In the summer, we love firing up the grill though! Flank steak is one of our family’s favorite things to throw on the grill. I always like to use a marinade with flank steak which helps make the meat more tender. Flank steak cooks quickly on the grill, in about ten to fifteen minutes, if you like your meat medium like we do.
Try to let your steak marinade overnight for up to 24 hours if possible. The longer it can marinade the more tender and flavorful your meat will be.
Before grilling your steak, mix up a delicious tomato olive relish to dress up your meal and add even more flavor and some spectacular color!!
After taste testing this dish for me my husband declared it was “heavenly!” In fact, he made the same comment a few more times that evening. Needless to say, it was a huge hit at our house and the combination of the tender flank steak with the delicious tomato olive relish is a winner!!
Ingredients Needed
- Flank Steak
- Honey
- Soy Sauce
- Red Wine Vinegar
- Garlic
- Dried Rosemary
- Red Chili Flakes
- Tomatoes, grape or cherry tomatoes
- Olive Oil
- Red Onion
- Basil, fresh
- Garlic
- Black Olives
- Green Olives
- Balsamic Vinegar
- Salt and Pepper
How to Make Tomato Olive relish
- Slice grape tomatoes and olives in half and place in bowl.
- Dice red onion into small pieces.
- Thinly slice basil.
- Combine olive oil, red onions, basil, garlic and balsamic vinegar and add to tomatoes and olives.
- Stir to combine.
- Cover and refrigerate for 1-2 hours before serving.
Tips
- Make the relish ahead of time to allow the flavors to combine.
- Do not over cook your flank steak. This will make the steak tough.
- Cut flank steak against the grin. 1/3 inch slices is ideal.
- Using multi colored grape tomatoes adds even more fun color to the relish.
How to Grill Flank Steak
- Grill your flank steak over medium heat. Cook on each side for about 5-7 minutes, depending on how thick your flank steak is.
- For medium, grill the flank steak to 155 degrees F, medium is 160 degrees F. Use a meat thermometer for best results. Cutting into your steak to check the doneness will release the juices and dry your meat out. After you remove your meat from the grill it will continue to cook so always remove your flank steak from the grill about 5 degrees F before your desired temperature.
- Slice your flank steak going against the grain for the most tender cut. Place on a serving dish and then top with your tomato olive relish and serve!
