Since temperatures have been pretty high this past week, I convinced my husband to break out the grill for one last summer grilling recipe. This light and lean Grilled Flank Steak with Asparagus and Onions was a HUGE success!!

I love steak, but being a Weight Watchers member, I usually avoid this dish. So I was thrilled when I came across this flank steak recipe. It’s SO flavorful, and the asparagus and onions help to bulk up the serving, so it’s actually quite satisfying.

And with just a 4 Points per serving, this is a fabulous weight watchers steak recipe. Get those grills back out, folks!

Grilled Flank Steak Recipe, with Asparagus and Onions


  • 1 1/2 pound raw lean flank steak
  • 1 large red onion, cut into 1/4-inch-thick slices
  • 1 bunch of fresh asparagus spears
  • 2 tbsp balsamic vinegar
  • 1 tsp olive oil
  • 2 tsp fresh oregano, finely chopped
  • 3 garlic cloves, minced
  • 1/2 tsp black pepper, freshly ground
  • 1 tsp Kosher salt divided


  1. In a shallow glass dish (or sealable food storage bag), mix vinegar, oil, oregano, garlic and pepper. Add steak; turn to coat, making sure steak is coated with vinegar mixture. Cover dish (or seal bag); marinate in refrigerator for at least 30 minutes.
  2. Heat outdoor grill.
  3. Remove steak from marinade; discard marinade.
  4. Sprinkle steak with 1/2 teaspoon salt. Coat onions and asparagus with non stick cooking spray; sprinkle with remaining 1/2 teaspoon salt.
  5. Grill steak, turning once, until medium rare, about 15 minutes, or longer for desired degree of doneness. Let steak rest for 10 minutes.
  6. While steak is resting, grill onions and asparagus spears, turning occasionally, until lightly charred and tender, about 7 to 9 minutes.
  7. To serve, thinly slice steak against the grain and place on a serving platter; scatter onions over top.

Entire recipe makes 6 servings
Serving size is 3 ½ oz of steak, 4-5 asparagus spears and 1/3 cup onions
Each serving = 4 Points
