How to cook mushrooms in butter

Can I use white mushrooms instead of baby portobellos?

Yes, if white mushrooms is what you have on-hand, feel free to use those instead.

I find baby Bellas have a bit more flavor, so be sure to season your white mushrooms accordingly.

Additionally, you may need to add in a bit extra seasoning, garlic or butter depending on your taste preference.
