Ingredients

  • olive oil butter or ghee
  • 2 top sirloin steaks
  • sea salt
  • freshly ground pepper
  • 3 large shallots peeled and sliced
  • 1 large clove garlic peeled and minced
  • 6 oz crimini mushrooms thinly sliced (don't wash, if needed brush clean with a mushroom brush)
  • 3 Tablespoons butter
  • ¼ cup white wine if Whole 30, use white grape juice
  • 1 Tablespoon chopped chives for garnish

Instructions

  • Preheat oven to 300 degrees and place rack in center of oven.
  • Prep all ingredients so they are ready to go when needed.
  • Sprinkle both sides of steak with sea salt and pepper.
  • Place cast iron skillet or other heavy pan on medium/high heat and allow to heat for several minutes.
  • When pan is hot add enough olive oil, butter or ghee to generously coat bottom of pan.
  • When oil or butter are hot add meat to pan. You should hear the PSHHHHHH sound when meat is placed in pan.

Sear steak for 3 minutes each side. Place steaks in an oven safe dish and place in oven for 5 minutes to rest. While steak is in oven:

  • Add 2 tablespoons butter to hot steak pan, add shallots and turn heat down to medium.
  • Sauté, stirring frequently for three minutes, loosening any browned bits from the pan with spatula or spoon.
  • Add mushrooms and garlic, stirring until mushrooms release most of their juices (usually around five minutes (steaks should be out of the oven by now for medium rare)
  • Carefully add white wine (or white grape juice) to pan and sauté for 1 more minute, stirring. Sprinkle with a little sea salt and pepper.
  • Top steaks with shallots, mushrooms and white wine reduction. Garnish with chives. Serve.
