Lightly heat the butter in a large frying pan or skillet, and add the garlic powder, stir well.
Add the cleaned mushrooms to the butter garlic mixture and stir well.
Saute the mushrooms in medium heat for about 10 to 12 minutes or until the water content from the mushrooms is all released and evaporated and the mushrooms are cooked well.Adjust the heat to low and medium as needed and also stir in between.
Add the salt and black pepper powder also the pan, mix well and cook for another 1 to 2 minutes or until the mushrooms are roasted and start to turn light golden brown.
If you are using the extra spices as I mentioned in the ingredients (which will add more flavors to the mushrooms), add all those spices now, give a quick stir and saute for another 1 to 2 minutes so that the garlic butter roasted mushrooms will get sauteed once more in a blend of exotic spices. Now the delicious garlic butter mushrooms is ready to serve, make sure to serve this hot for best results!
Notes
You can serve the garlic butter roasted mushrooms as a yummy side with rice or use with pasta or any sandwich or whatever you like to pair it with.As I already mentioned, make sure to serve the mushrooms hot or warm for best results.
