  • Add oil and butter to cast iron or other heavy bottomed skillet and heat over high heat
  • Sprinkle steak with a few pinches of salt and pepper and add to skillet
  • Sear on each side until browned and caramelized, about 3-4 minutes per side
  • Remove steak from skillet and set aside
  • Add mushrooms, shallots, garlic and seasoning to skillet
  • Saute for 2-3 minutes until mushrooms start to soften
  • Add broth and allow to simmer for 5 minutes until it reduces in half
  • Stir in cream and add steak back to skillet
  • Allow to simmer until steak is cooked to preferred doneness (check with meat thermometer) approximately 2-4 more minutes


  • Steak thickness? Try to find thin steak (1/2 inch or 1.5cm) to keep the cooking time down
  • Mushrooms dry when cooking? Add a little more oil to the pan if needed
  • Serving kids - leave the steak to rest for 5 minutes and then slice the steak into smaller pieces
  • Too much sauce? This recipe makes a generous quantity of mushroom sauce. If you won't use it all, for example, if serving children, reduce the amount of cream. Try 1/2-3/4 cup of cream.
  • Leftover steak? Steak can be kept for 3-4 days in the fridge
  • Leftover mushroom gravy? Keep in an airtight container in the fridge for 4-5 days. The sauce is delicious served with chicken or white fish.
  • Freeze the mushroom sauce?¬†Leftover sauce can also be frozen¬†
  • No shallots? Use onion instead
