  • 1 tablespoon butter
  • 1 clove garlic
  • 150 g mushrooms sliced
  • 1/2 teaspoon dried thyme or fresh
  • 1/2 cup cream
  • 1/4 cup parmesan
  • Salt and pepper to taste
  • Finely chopped fresh parsley to serve



  • Melt butter over medium high heat in a wide based frying pan.
  • Finely mince the garlic and add the foamy butter. Add the mushrooms and thyme; stir to coat the butter. Sautè until mushrooms are lightly golden but still soft.
  • Add the cream and parmesan; season to taste. Cook stirring for 1-2 minutes until sauce has thickened. Remove from the heat and serve with finely chopped parsley.


  • Place a small handful of parsley to the mixer bowl. Chop 10 sec/speed 10. Scrape and repeat if needed. Scrape into a small bowl and reserve.
  • Add the garlic and butter to the mixer bowl (no need to clean) and chop 3 sec/speed 7. Scrape down sides of bowl; cook 4 min/100°C/speed 1.
  • Add the sliced mushrooms and thyme to the butter; cook 5 min/110°C/reverse/stir. Add the cream, parmesan and season to taste; cook 3 min/110°C/reverse/stir. Remove from the mixer bowl and serve with reserved parsley.


  • I use button mushrooms, but any mushrooms of choice can be used. In the thermal method I do not use the mixer to chop the mushroom as I prefer them sliced in the sauce.
  • Cream can be replaced with coconut cream or stock/bone broth if preferred.
  • Parmesan can be swapped for any cheese or for a cheese free sauce add 1 tablespoon of nutritional yeast for a cheesy flavour.
  • Any herbs of choice can be used.
  • The sauce can be made in bulk and stored in the fridge for up to 4 days or frozen as part of a meal or in individual serves.
  • When reheating sauce be careful to do so over low heat to avoid splitting the cream.
  • The nutritional values have been calculated using the recipe ingredients as listed for 2 serves.
  • This sauce is 4g net carb per serve.
  • The creamy keto mushroom sauce can be used as a sauce to be served with vegetables or protein. Alternatively, it can be used as a keto pasta sauce or over keto toast.
  • Add some chopped bacon or chicken for a delicious meal.
