These easy Sauteed Mushrooms are an elegant but easy side.  Serve over grilled steak, or along side beef tenderloin or grilled chicken, or simply eat by itself as a light dinner.


  • 3 tablespoons of butter
  • 2 tablespoons Worcestershire Sauce
  • 1 lb white button mushrooms halved
  • 1 large sweet Vidalia onion thinly sliced
  • 3 cloves garlic minced
  • Salt and pepper to taste


  1. Melt the butter over medium high heat in a large skillet. Stir in the Worcestershire Sauce.  Add your mushrooms and cook until they start to turn golden brown; approximately 5 minutes. Stir about every 1 1/2 minutes. Add the onions and cook until the edges brown and the onions become translucent; approximately 5 minutes.  Continue stirring every 1 1/2 minutes
  2. In the final minute reduce the heat to low and add the minced garlic; stirring continuously.  Salt and pepper to taste.


  • After washing or wiping the mushrooms dry them well with a paper towel.
  • Do not burn the melting butter.  The key is to stay close by and have everything prepped and ready to go.
  • Cook mushrooms over medium high heat.  They release a lot of moisture so in order for them to brown properly they must be cooked over fairly high heat and stirred frequently so they do not burn.
  • Add the onions when the mushrooms are starting to turn golden brown.  The onions should be lightly browned on the edges and translucent.  It does not take long and they too should be stirred frequently.
  • Add the garlic during the last minute of cooking.  Reduce the heat to low and stir frequently.  Garlic burns easily and tastes bitter when it burns.
