Ingredients You Need
Mushrooms – Almost any kind of mushroom will work. I combined shitake and brown mushrooms (also known as gourmet, cremini/crimini, or chestnut mushrooms) in this variation. However, medium-sized portobello mushrooms can also be used.
Butter or Oil – You can use butter, margarine, or even olive oil so it can produce a beautiful color while maintaining the juicy inside. Later on, you can put some butter to adorn them.
Salt – To balance and enhance the overall flavor. Preferably use sea salt or Himalayan salt.
Optional garnishes: Lemon juice and garlic cloves — these provide a really flavorful touch to buttered mushrooms. However, it’s not necessary because just roasted mushrooms are delicious as they are!
How To Make
STEP 1: Preheat oven to 200°C/392°F.
STEP 2: Remove the stems from the mushrooms and spread them on a baking tray covered with parchment paper.
STEP 3: Cut ½ to 1 inch of margarine (depending on the size of the mushroom) and place it in the mushroom hole so it can spread when melted. Salt each mushroom with a pinch of salt. Also, toss with some minced garlic cloves if you like (totally optional).

STEP 4: Place in the oven and roast for about 20 minutes – do not toss or turn.
STEP 5: Remove from oven, sprinkle with some lemon if you like, and serve immediately! Enjoy!
