So, how long does it take to boil mushrooms? Well, the general rule of thumb is to boil them for around 3-5 minutes, or until they're tender and have released their moisture. But, like I said, it depends on the type of mushroom - button mushrooms might only need 2-3 minutes, while portobello mushrooms might need a bit longer, around 5-7 minutes.
It's kind of like boiling potatoes - you want to make sure they're tender all the way through, but you don't want to overcook them or they'll be mushy. And just like potatoes, mushrooms can be a bit tricky to cook, because they can go from undercooked to overcooked in just a few minutes. But with a little practice, you'll get the hang of it and be boiling mushrooms like a pro in no time.
One thing to keep in mind when boiling mushrooms is that they'll release a lot of liquid as they cook. This can make the water look a bit cloudy or murky, but don't worry, that's just the mushrooms doing their thing. It's like when you boil broccoli and the water turns a bit green - it's just the veggies releasing their natural goodness into the water.
