Time to get excited! You most likely have most of the ingredients in your kitchen to make this low carb mushroom sauce, so many even be able to avoid heading to the grocery store.
- Butter - The melted butter is the perfect element to give the mushrooms a rich flavor. I don't recommend skipping the butter because it makes a huge difference in the end result.
- Olive Oil - Paired with the butter, you will get good and healthy fats, and it just plain tastes good too.
- Onion - Besides adding flavor, onions are great to add to the dish because they are a great source of vitamin C, potassium, vitamin B6, and folate.
- Garlic - I enjoy adding 2 cloves of garlic, but you can adjust that amount if you wish. It's a good way to get a boost of iron, copper, vitamin B, and manganese!
- Baby Bella Mushrooms - The key ingredient in keto mushroom sauce is naturally the mushrooms. They are the star of the show for a good reason...because they are delicious.
- Beef Broth - While I prefer beef broth because it brings out the flavor of the mushrooms in the sauce, you could swap it for vegetable broth if you want.
- Cream Cheese & Heavy Cream - You can't get much better than combining these two super creamy ingredients. They will give you the ultimate results every time.
- Salt & Pepper - Naturally, a dash of salt and pepper can make a boring dish and transform it into something amazing. So don't skip adding it in because it makes a huge difference.
- Xanthan Gum - To thicken the sauce, my go-to is the xanthan gum.
A couple more options are to add a dash of Worcestershire sauce for some zing and chopped fresh parsley for color.
How To Make Keto Mushroom Sauce
Step One: Start off by melting the butter with the olive oil in a large skillet using medium heat.
Step Two: Once hot, add the onion and garlic to the pan and cook until softened. Then add the sliced mushrooms and continue cooking until they become tender. Remove the mushroom mixture from the skillet and set it aside.
Step Three: Pour in the broth and add the cream cheese. Whisk until the cream cheese has melted, then sprinkle with salt and pepper. Pour in the heavy cream and stir until smooth and creamy.
Step Four: Add half of the mushroom mixture back into the skillet—puree using an immersion blender until it's smooth. Sprinkle the xanthan gum on top and whisk until it's smooth. Add the rest of the mushrooms on top and serve the keto creamy mushroom sauce hot. Enjoy!
