So, what are the signs that your sausages are cooked? Well, for starters, they should be brown and crispy on the outside. This is a good indication that they're cooked through, but it's not the only sign. You should also check for firmness, as cooked sausages will be firmer to the touch than raw ones.

Another way to check is to cut into the sausage. If it's cooked, the juices will run clear, and the inside will be white and firm. If it's still pink or red, it needs a bit more cooking time. Easy peasy!
