Braised Flank Steak in the Oven


This is one of my family's favorite recipes. We pair it with mashed potatoes and use the leftover sauce from the pan as gravy. So good, and it makes the house smell amazing as it cooks!

  • 1 ½ cups water

  • 1 cup steak sauce (such as A1®)

  • 1 envelope onion soup mix

  • 1 (2 pound) flank steak


  1. Preheat the oven to 350 degrees F (175 degrees C). Line a 9x13-inch baking pan with foil.

  2. Whisk water, steak sauce, and soup mix together in a small bowl. Pour a little into the bottom of the prepared pan. Add the steak, then the remaining sauce. Cover with foil.

  3. Bake in the preheated oven until tender and hot and slightly pink in the center, 1 to 2 hours. An instant-read thermometer inserted into the center should read 140 degrees F (60 degrees C) for medium.
