  • 1 tablespoon butter
  • 8 ounces whole white button mushrooms (227g)
  • 1/2 white onion finely diced
  • 4 garlic cloves minced
  • 1/2 cup whipping cream (double cream) (120ml)
  • 1/2 tablespoon fresh tarragon
  • 1 teaspoon dijon mustard


  • Place a skillet over a medium heat and add the butter, diced onions, minced garlic and mushrooms.
  • Cook for 10 minutes until the mushrooms start to brown.
  • Add the cream, tarragon and mustard and stir to combine.
  • Cook for 5-10 minutes, stirring occasionally until the sauce thickens.


  • If you use dried tarragon instead of fresh, add it to the pan with the onions so that it has time to soften and flavor the dish.
  • Use a large pan and don't overcrowd the mushrooms. If you add too many mushrooms to a small pan they will steam rather than brown and can turn soggy.
  • Garnish the dish with parsley just before serving for a burst of fresh flavor.
  • If serving as an appetizer, this recipe will serve 2.
  • Nutritional values are based on one of four servings and are an estimate only.
