My house was burned in a fire.
This bread is toasted well.
"This meat is thick, so I think it'll be a while until it's cooked." "I think it'll cook while you're doing the dishes."
You know how 焼く is to cook? Well, 焼ける is to be cooked. This is when you're not doing the actual cooking, and the cooking is just happening. Can also refer to when something burns, making it to burn as well.
The reading is the same as 焼く, so just use that knowledge and apply it here to be able to read this too.
