A healthy topping adds complementary flavor and fresh appeal to grilled flank steak. It’s easy to make and leftovers offer an ideal protein topper to a big dinner salad another night.



In many ways, flank steak is the perfect entree after a busy day.  The prep and cook time is mere minutes, the flavor is outstanding, and leftovers will reward you with another quick, delicious-and no-cook-dinner.

I’m a big fan of spice rubs for the flavor they impart and the ability to sprinkle them onto meat just moments before grilling.  Rubs are perfect for those evenings when you didn’t plan ahead—no extended marinating time required–but still want a great dinner.

A simple bag of greens, a baked sweet or regular potato (hurried up in the microwave, if need be), and even your favorite frozen veggies will round out a wonderful meal.

One of my favorite quick dinners consists of thinly sliced leftover flank steak served atop a salad of mixed greens, halved grape or cherry tomatoes, corn, chopped celery, leftover roasted broccoli, or whatever else I might have on hand. Then I drizzle with leftover Gorgonzola dressing from the recipe below, or with homemade ranch dressing.  It’s like one of those fabulous restaurant salads, only cheaper and better!  A side of cornbread or a slice of your favorite quick bread makes the meal extra special.

Because I love how the flavors of blue cheese and tomatoes compliment the steak, I devised a topping several years ago starring these two ingredients.  Sometimes, you see blue cheese and butter combinations melting over a hot steak, but I like the idea of something a little lighter yet equally flavorful. Plus, this topping is incredible spilled over into most basic veggie, salad, or potato side dishes.

Greeked-Out Gorgonzola Dressing -- thick and delicious yet healthy

Grilled Flank Steak with Greeked-Out Gorgonzola and Tomato Salsa
For the Flank Steak
  • Flanks steaks, grass-fed if possible  (number depending upon how many you are serving; plan for leftovers!)
  • Montreal steak seasoning (see notes for options)
For the Greeked-Out Gorgonzola and Tomato Salsa
  • 1/4 cup olive oil
  • 3/4 cup (a 6-ounce cup) plain Greek yogurt  (may use fat content of choice)
  • 4 ounces blue cheese, crumbled (I often use gorgonzola, but any basic blue is fine)
  • 1 teaspoon Worcestershire sauce
  • 2 garlic cloves, minced  (If I’m in a hurry I sometimes skip this)
  • Kosher or sea salt and freshly ground pepper  (I use about a 1/2 teaspoon of sea salt and a few turns of the pepper grinder, but use how much you like)
  • 2 tablespoons fresh chives (optional but provide great added flavor)
  • Buttermilk for thinning to desired consistency (can use regular milk or even water–I like approximately 3 tablespoons of buttermilk)
  • A pint box of tomato grapes
  • Chopped chives or parsley, for garnish
For the Flank Steak
  1. Allow steaks to sit at room temperature for about 30 minutes prior to grilling.  Sprinkle seasoning over both sides of the steaks.  Over high heat, grill for approximately 6-8 minutes per side for medium rare. This will depend a bit on the thickness of the steaks.  (Our last steak was about 1-inch thick and took the higher end of this range.)  Flank steak will be more tender when cooked to medium rare.
  2. Allow the steak to rest for five minutes before slicing to allow the juices to redistribute.  Then, slice thinly across the grain. Spoon the Greeked-Out Gorgonzola and Tomato Salsa over the top.
For the Greeked-Out Gorgonzola and Tomato Salsa
  1. In a large bowl, whisk together the oil, yogurt, Worcestershire, garlic, and salt and pepper, to taste.  Stir in the blue cheese and chives, then add a little buttermilk to reach your preferred consistency.  Cover and refrigerate at least 1 hour before serving.  Tip: It’s a good idea to keep the dressing on the thick side, as the juice from the tomatoes will thin it slightly.  You can thin more for use as a salad dressing, if you like.
  2. When ready to serve, cut the amount of tomatoes you wish to use in halves or quarters.  Then, toss the tomatoes with the dressing to coat and sprinkle with additional herbs, if desired.  The remaining dressing will be perfect on a big dinner salad topped with leftover sliced steak for an easy dinner later in the week.
  • As an option, The Herb Shop at Lancaster Central Market offers an all-natural version of Montreal Steak Seasoning called Quebec Seasoning.  I have also tried and enjoyed an all-natural version from The Mystic Blue Spice Company.

    Made this tonight…was so good! Though it didn’t look as pretty as your picture 🙂 I used scallions instead of chive (personal preference) and had a thinner piece of meat so only cooked it for 5 min each side. Husband loved it and we agreed it will be a great summer meal when we have dinner guests!
