All quantities are in the recipe card below.
- butter – this gives the best flavour. You can use salted or unsalted butter. Remember to season to your liking accordingly.
- Garlic – fresh crushed garlic tastes better than dried garlic flakes, but you can use either.
- Mushrooms – fresh, raw, peeled, and sliced. Do not use dried mushrooms that have been rehydrated, they will make the sauce too watery.
- Cream cheese – use the full-fat variety. The lite, light, or spreadable won’t make a very creamy thick sauce.
- Double/heavy cream – you can adjust how much you add to the sauce. If you wish to have a more pourable sauce, add an extra tablespoon or two at a time. If you wish to have a thicker sauce, only use half the stated quantity.
How to cook the perfect steak
To cook the perfect steak bring the raw steak to room temperature for at least 20 minutes before you are going to cook it. Do NOT oil the pan, but instead, brush both sides of the steak with oil and season with salt and pepper.
Preheat your frying pan, skillet, or griddle to high heat. Set your kitchen timer and cook your steak on high for the recommended time on each side.
These cooking times are approximate and you may vary the time depending on the thickness of your steak. Always allow your steak to rest before serving.
1.5cm (0.6 inch) steak cooking times.
- Rare: 1-1.5 minutes on each side
- Medium: 2-3 minutes on each side
- Well done: 3-4 minutes on each side
2-3cm (1 inch) steak cooking times.
- Rare: 2-3 minutes on each side
- Medium: 4-5 minutes on each side
- Well done: 5-6 minutes on each side
How to make it?
After you have cooked your steak, remove it from the frying or skillet and keep covered on a plate until it is time to serve. Using the same frying pan melt the butter and cook the crushed garlic and sliced fresh mushrooms until cooked and tender.
Add the cream cheese and stir while it’s melting so to avoid any lumps in your creamy keto sauce. Add heavy cream/double cream until you get the desired thickness of the sauce.
You can create a thick sauce, or add extra cream t make it a pourable sauce.
How to store it?
I never have leftovers, but if you do, store them in an airtight container in the fridge for up to 3 days. I prefer to use a glass container so the garlic does not impart onto a plastic container which is difficult to remove.
The mushroom sauce can be frozen in ice cube trays for quick and easy individual servings. Once frozen in ice cube trays, remove and place in a ziplock bag for up to 3 months
How to serve it?
Creamy mushroom sauce is incredible when poured over steak, stuffed chicken, pork chops, keto meatballs, or vegetable side dishes. The sauce can also be used cold as a mushroom dip with Fat Head crackers.
Recipe FAQ

What is ‘double cream’?
Double cream is the same a heavy cream or whipping cream.
In NZ, Double Cream is just cream
Looks yummy but that would be a starter in our house 😉
Yes! And…. add some fresh thyme & 3 T white wine while you saute the garlic. Proceed as above ? spool yummy…
Soooo yummy, not spool!
Incredibly easy and delicious mushroom sauce. I’ve been missing sauce/gravy on my steak quite a bit and have been substituting by topping a fried egg on top instead. This sauce is a great alternative and is almost as quick and easy as frying the egg. Plus you have extra to go in the fridge for more uses. I used thickened cream instead of double cream since it’s cheaper and doesn’t go off anywhere near as quickly. I’ve found little difference in flavour between the two types of cream so I usually go with the thickened.
Sauté mushrooms in butter, add Worcestershire sauce and sour cream. Heat until warm serve on steak.
I made this mushroom sauce tonight… devine! I doubled the amount of mushrooms as I love mushrooms, will definitely make again.
What is considered a serving for this sauce?
Great advice! Thank you!
Awesome sauce, I’ve used it with butterfly chicken breast with soya cream instead.. oh and I popped in a handful of spinach.. thanks, just wish I could post a pic of my version too 🙂
Low carb is great especially for diabetics; however, diabetics are at big risk for cardio vascular and heart problems. Those problems require the consumption of less fat, especially saturated fat. Do you have any ideas for low carb and low fat sauces?
In addition, I did not see a portion size under the Nutrition Facts section.
Yes those with diabetes (T1 and T2) are at more risk for heart disease because of the inflammation and vascular events that occur through chronic high blood sugars, not through the consumption of fat. Even the World Heart Federation president says fats are protective, carbs are harmful, you can read more here. You may also want to read the cholesterol myth too. There is so much old and outdated science out there yet the guidelines havent changed.
This sauce changed the game for me. Not only is it good on steak but really good on everything! It is rich so I’d be weary and have a portion on the plate as to not over indulge. Super easy to make and is just divine! Will be making this all the time! Thank you 🙂
