I am French, and if there’s a sauce my mum always made for us as a kid, it’s a mushroom sauce.
While most recipes call for corn slurry and cornstarch, my mum used to thicken her sauce with cheese, very French-style! And therefore, it contains fewer carbs while being utterly delicious.
The secret to a flavorsome mushroom sauce are a combination of 4 ingredients:
- Butter and olive oil a combination of both makes the sauce perfect.
- Cream cheese
So let me share with you this amazing mushroom sauce with you.
What’s A Keto Mushroom Sauce?
This keto mushroom sauce is a creamy, rich sauce, not a thick sauce made of corn slurry, and it’s very low in carbs, with only 4 grams per serving.
Therefore it’s a perfect sauce for steak, chicken breast, or steamed vegetables.
How To Make Keto Mushroom Sauce
It’s very easy to make this low-carb mushroom sauce for steak or vegetables.
All you need to make the sauce are:
- Butter – I prefer using local grass-fed butter.
- Extra Virgin Olive Oil
- Button Mushrooms – white or brown
- Lemon Juice – Some people prefer white wine and it actually depends on how you intend to use the sauce. White wine goes well with a steak, while lemon juice matches chicken or vegetables better.
- Chicken Broth
- Heavy Cream – Heavy cream is a keto-friendly dairy product.
- Cream Cheese – Softened.
- Garlic Cloves
- Ground Pepper
- Parmesan – Freshly grated not box parmesan, this won’t thicken the sauce.
First, warm olive oil and butter in a skillet over medium-high heat. Stir in shallots and cook for 1 to 2 minutes until fragrant.
Stir in sliced mushrooms and cook until golden brown and the water from the mushroom evaporates. It takes about 4 to 5 minutes while stirring occasionally.
Then, season with salt and pepper to taste. Next, add crushed garlic and stir in lemon juice to deglaze the fat in the skillet.
Adding lemon juice creates a huge sizzling in the pan, and that’s what you want.
Then, add chicken broth, cream juice, and heavy cream, stir to incorporate, and simmer for 3 to 4 minutes on medium heat, don’t boil until it slightly reduces.
Enriching The Sauce
This sauce is a rich, creamy sauce, slightly thick and flavored with Parmesan.
In the end, enrich the sauce by stirring freshly grated parmesan. Cook until melted and remove it from the heat.
Below are some allergy swap options if you need:
- Dairy-Free – You can replace the butter with dairy-free butter, coconut oil, or more olive oil. Next, swap the heavy cream for soy cream or canned coconut cream. Use dairy-free cream cheese instead of classic cream cheese. Finally, skip the Parmesan, use a dairy-free Parmesan brand, or add two tablespoons of nutritional yeast for a vegan option.
- Vegetarian – Replace the chicken broth with vegetable broth.
- Lemon-Free – Swap the lemon juice for white wine or apple cider vinegar.
You can make ahead the keto mushroom sauce and store it in an airtight container in the fridge for up to 3 days.
You can also freeze sauce leftovers and thaw them in the fridge the day before.
