Skirt Steak with Caramelized Onions and Mushroom Sauce

This marinated Skirt Steak is perfectly complemented by savory root vegetables, a couple sprigs of rosemary, and — our favorite — a rich, wine sauce. If you don't have Skirt Steak, a Flank or Bavette Steak would work well; you could even try this recipe with Chicken!

  • 2 tsp garlic powder
  • 2 tsp onion powder

  1. Marinate skirt steak with coconut aminos, garlic powder, onion powder and salt and pepper. Rub into skirt steak 30 mins prior to cooking.
  2. Saute mushrooms and onions until caramelized. Add red wine until reduced. Add 1 tbsp butter. Mix beef base and water and pour into pan to let simmer. Add Rosemary. (You can add more broth depending on how much sauce want to make).
  3. On medium heat, add cornstarch to thicken sauce. Continuously mix to avoid clumping.
  4. Pre-heat a separate skillet to medium-high heat. Add butter and place steak in pan. Sear, then flip. Repeat for 30 seconds on each side. Place steak in oven for 15-20 min at 350 degrees.
  5. Let steak rest and then cut against the grain and on a bias starting with the short end.
  6. Place on top of mushroom and onion sauce and enjoy!
