How to gain weight

Hi, had crohns for 13 years and been the same stable weight since diagnosed. Now 26 (M) and still sitting at 56kg. While im feeling good with no issues other than not putting on weight what can I do to help gain?

Im aware of calorie intake but still nothing. Good news im not losing weight but can't gain to save my life

Thanks in advance
