- 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
- 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.
- Preheat your oven to 400°F and line a baking sheet with parchment paper.
- 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.
- 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.
- 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.
- Add any juices from the baking sheet to the onion mixture.
- 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.
