The best way to thaw portobello mushrooms is to leave the portion you need in the fridge for a couple of hours or overnight and let it thaw gradually.
You can also add the frozen mushrooms directly into the dish if you are going to cook them. If they have been sautéed before it is best not to bake or cook them for too long as they can get overcooked.
If you are in a hurry, you can also thaw them on the kitchen counter or in the microwave.
But if you opt for this method the mushrooms must be consumed immediately as there are high chances of them spoiling faster.

Does Portobello Mushroom Freeze Well?
