Microwave cooking temperatures can vary massively, so there will be a little trial and error when you first make this, so you can find the exact cooking time using your microwave. Perfect bacon should be crispy in our opinion. In our microwave (our is 1,000 watts) it takes about 4 minutes and this is what we have found when we have made this in over microwaves when travelling too. But use that as a guide. It will depend on how powerful your microwave is, the type of bacon used and how you like it cooked. As a general rule, it will take about 1 minute per rasher of bacon. If you want it extra crispy, then cook it for a minute longer. The bacon will get crispier as it cools too. If you want it more chewy rather than crispy, then cook it for 3 to 3 and a half minutes.
