One of my favorite ways to make grilled steak in the summer. Topped with fresh chopped tomatoes, red onion, balsamic and oil. It’s fresh and a great way to enjoy those end-of-summer tomatoes!

This Grilled Steak topped with fresh chopped tomatoes, red onion, balsamic vinegar, and olive oil is one of my favorite ways to make steak in the summer. A couple more of my favorite grilled flank steak recipes are this Grilled Flank Steak with Black Bean and Corn Salsa and Grilled Balsamic Steak with Tomatoes and Arugula.

Flank Steak With Tomatoes, Red Onion and Balsamic

This summer grilled steak recipe is fresh and flavorful and a great way to enjoy summer tomatoes. The tomatoes and red onions are seasoned with salt, pepper, balsamic vinegar, and olive oil and topped with whatever combo of fresh herbs you have on hand, like basil and oregano.

How long do you cook steak on the grill?

Turn the grill on high heat and cook the steak for about seven minutes on each side for a medium-rare steak. The internal temperature should be 135 degrees, and for a medium steak with a warm pink center, cook it to 145 degrees. After you pull the steak off the grill, let it rest for about five minutes before slicing.

What to Serve with Grilled Steak

This grilled flank steak would be delicious with a side of grilled lemon-parsley potatoes and asparagus. Some other side dish options are this Grilled Corn Salad with Feta, Grilled Vegetable Orzo Pasta Salad, and Buttermilk Mashed Potatoes. You could also serve the steak and tomatoes as a salad over mixed greens or arugula.

Variations:

  • Swap the balsamic vinegar with red wine vinegar.
  • Switch out the red onion for shallot.
  • Add avocado to the tomato topping.
  • If you can’t find flank steak or London broil, use flat iron steak.
  • Serve the tomato mixture over chicken or salmon.
  • If you don’t have an outdoor grill, you can use your broiler or purchase an indoor grill pan (this is the one I use).

  1. Absolutely delicious and so easy! I let the steak marinade in the dry seasonings (using extra garlic and onion powder) as well as some Worcestershire sauce for a few hours beforehand. We like to serve the steak and relish in sandwich form with shredded romaine lettuce and grilled mini naan brushed with garlic bread spread.

    Another excellent recipe from Gina.  We used Top cut sirloin.  We did add just a little sugar.  It was a bit too sour for me (relish).  Gina – if you have a better suggestion for the sugar I would appreciate it. Served with new potatoes.  We will definitely have this recipe again.
