Ingredients:
Butter – For luscious taste and texture. Feel free to use olive oil if you prefer.
Onion & garlic – Can be substituted for onion and garlic powder if you want.
Salt & pepper – To taste, but please know we use Diamond kosher salt in our recipes unless otherwise noted. Other types of salt can be saltier, so taste as you go.
Mushrooms– Sliced. We’d recommend portobello or shiitake & we used a mixture of the two!
Beef broth – For a classic flavor. Can be substituted for chicken, vegetable, mushroom broth or white wine.
Heavy cream – To make this sauce incredibly creamy and luscious!
Dijon mustard & Worcestershire sauce – To really create a deep, well rounded flavor.
Fresh thyme – Really adds such a delicious flavor. Dried can be used instead.
How To Make Creamy Keto Mushroom Sauce:
Step 1: Cook the Aromatics
Heat a large skillet, pot or dutch oven over medium heat. Melt 2 tablespoons of butter, and add in onions with a pinch of salt. Cook until soft and translucent, about 5-7 minutes. Add in garlic and thyme and cook until garlic is fragrant, about 30 seconds.
Step 2: Cook the Mushrooms
Add in remaining 2 tablespoons of butter and melt, followed by the mushrooms. Season mushrooms with more salt and pepper and cook until softened, about 5 minutes.
Step 3: Add the Liquids
After mushrooms are softened, stir in beef broth and heavy cream.
Step 4: Add the Finishing Touches
Stir in dijon mustard and Worcestershire sauce. Taste and adjust seasonings to suit your personal preference. Simmer gently to allow the sauce to thicken slightly and the flavors to meld, about 3-5 minutes.
Step 5: Serve & enjoy!
Serve and enjoy! You can’t go wrong here. Our preference? Drizzling it all over a juicy steak!
Tips For The Best Keto Creamy Mushroom Sauce:
Don’t heat the cream too high, or the sauce with curdle or separate. This goes for reheating as well. Reheat gently at low to medium heat on the stovetop, or at lower power in the microwave.
Reheat in the air fryer at 350°F for up to 4 minutes, being careful not to burn the garlic and herbs.
Notes:
Garlic and onion can be substituted for garlic and onion powder if preferred.
If dairy free, replace heavy cream and butter with vegan butter and full-fat coconut milk.
If vegan, follow dairy free instructions and replace beef broth with a vegetable broth. Omit worcestershire sauce or replace with soy sauce or tamari.
