We used three types of onions to create both an eye-appealing and tasty sensation.


Unpacked brown sugar

3 tbsp(s)

Balsamic vinegar

4½ tsp(s)


3 medium, yellow, cut in 1/2 inch-thick slices

Vidalia onion

1 large, cut in 1/2 inch-thick slices

Red onion

2 medium, cut in 1/2 inch-thick slices

Table salt

1 tsp(s)

Black pepper

¼ pinch(es)

Uncooked lean flank steak

1¼ pound(s)


  1. Heat grill to medium.
  2. Combine sugar and vinegar in a small bowl. Brush onions with vinegar mixture and sprinkle with 1/2 teaspoon of salt. Grill onions until soft and caramelised, turning occasionally, about 45 minutes. (Note: To prevent onions from falling through grill rack, either skewer them or use a grill basket, foil with slits or a cooling rack.)
  3. Sprinkle steak with remaining 1/2 teaspoon of salt and pepper. Place on grill 30 minutes after onions. Cook 15 minutes, turning once, or until medium rare. Let rest 10 minutes and slice thinly against the grain. Yields about 4 ounces of steak and 2/3 cup of onions per serving.
