Notes

  1. Butter and oil. Both butter and olive oil are used in this recipe to add to the richness of the sauce. It also makes the butter seem to go further and really coat the mushrooms when they're sautéing.  
  2. Mushrooms. We used cremini mushrooms (also called portobellini, brown button mushrooms or baby bellas), but white button mushrooms will work just as well. You can also experiment with a mix of different kinds of mushrooms.
  3. Cream. It's ideal to use a high fat cream like heavy cream or whipping cream in this sauce, but light cream also works just fine. If you use light cream though you will almost certainly want to thicken it with cornstarch. 
  4. Thicken with cornstarch. Cornstarch is optional. It depends on how thick you like your sauce. Just simmering it for a few minutes so that the sauce can reduce slightly may result in the ideal thickness for you. If you prefer it a little thicker, then mixing some cornstarch with water into a paste and then adding it in will thicken it more. Our photos show the sauce after being thickened with cornstarch.
  5. Make It Dairy-Free. You can make a dairy-free version of this sauce if you use a vegan butter like Earth Balance instead of the dairy butter and use coconut cream (canned, unsweetened) instead of heavy cream. 
  6. Storing leftovers. Keep any leftover sauce in a covered container in the fridge for 3-4 days. Reheat on the stove or in the microwave. If you find it too thick when reheating, add in a little vegetable stock. It's not ideal for freezing.
