Creamy Mushroom Sauce For Steak Recipe
Ingredients Needed
- Mushrooms
- Onions
- Dijon mustard
- Worcestershire sauce
- Single cream
- Salt and pepper*
*If you’re making this creamy mushroom sauce in the same pan you cooked your steak in, only add a small amount of salt and pepper — make sure to taste first, as the steak juices may already add flavour. If you’re using a separate pan, season to taste.
How To Make Creamy Mushroom Sauce For Steak
- If you’re using the same pan you cooked your steak in, go ahead and toss in your finely chopped onions straight away. If not, preheat a pan, add a little ghee, then sauté the onions until soft. (Skip the salt and pepper for now if you’re using the steak pan — the leftover flavours usually do the job. You can always season at the end after tasting.)
- Thinly slice your mushrooms and add them to the pan once the onions have softened. Cook until the mushrooms are tender and start to brown.
- Next, stir in ½ to 1 tablespoon of Dijon mustard. I used a full tablespoon, but honestly, I think ½ tbsp would be perfect next time — feel free to adjust to your taste.
- Pour in your single cream and give everything a good stir to combine.
- Let the sauce simmer gently until it thickens slightly.
- Spoon it generously over your steak and enjoy every bite!
