My Top Tips for Making Creamy Mushroom Sauce
If your sauce turns out a little too thin, feel free to whisk in a tiny bit extra cornstarch to thicken it right up.
If you love that golden-brown, caramelized flavor, try sautéing the mushrooms in a skillet first and stirring them into the sauce right at the end.
Another delicious idea: Dice up some chicken breast, brown it in a separate skillet, and toss it right into the sauce for a quick, hearty dinner!

Can You Make This Sauce Ahead of Time?
You can totally make this sauce ahead and reheat it later! Just store it in the fridge and warm it up gently over low heat on the stovetop or in the microwave.
It will stay fresh in the refrigerator for about 1 to 2 days.
Just make sure to cover it tightly or keep it stored in an airtight container.
Can You Freeze Creamy Mushroom Sauce?
Let the sauce cool down completely, then transfer it to an airtight container or a freezer-safe bag.
It will keep nicely in the freezer for about 2 to 3 months.
