Ingredients

  • 1 ½ lb beef flank steak
  • 4 teaspoons Dash Table Blend or Dash Onion & Herb seasoning blend, divided
  • ½ tsp black pepper ground
  • 4 tsp canola oil
  • 2 cups onion, halved and thinly sliced
  • ¾ cup beef broth low sodium
  • 2 tbsp balsamic vinegar
  • 1/2 tbsp Worcestershire sauce

Juicy, perfectly seared steak seasoned with the savory Dash™ Table Seasoning blend, served alongside caramelized onions simmered in a rich balsamic and broth reduction. This dish offers a delicious combination of tender steak and sweet, tangy onions for a satisfying, restaurant-quality meal.

Directions

  1. Rub the steak all over with 2 tsp of Dash™ Table Blend and black pepper. Set aside to come to room temperature while you prepare the onions.
  2. Preheat your oven to 400°F and line a baking sheet with parchment paper.
  3. Heat 2 tsp of oil in a heavy skillet over medium-high heat. Sear the steak for 2-3 minutes on the first side until well browned, then flip and sear for an additional 2 minutes. Transfer the steak to the prepared baking sheet and set aside.
  4. Wipe out any burnt oil from the skillet with a paper towel. Return the skillet to medium heat and add the remaining oil and sliced onions. Sauté for 2-3 minutes until the onions begin to soften. Add balsamic vinegar, and Worcestershire sauce, and 2 tsp of Dash™ Table Blend continue cooking, stirring frequently, for 10-15 minutes until the onions are soft and the liquid has reduced by about two-thirds. Add additional broth if needed.
  5. While the onions are cooking, place the steak in the preheated oven for 6-8 minutes, or until it reaches your desired level of doneness. Remove the steak from the oven, tent with foil, and let it rest for 10 minutes.
  6. Add any juices from the baking sheet to the onion mixture.
  7. Slice the steak thinly against the grain and serve with the balsamic onions on top.

Tips

  • Chef’s Tip -When searing the steak, avoid moving it around in the skillet. Let it sit undisturbed to achieve a deep, flavorful crust. This crust enhances both the texture and taste of the finished dish.
