Notes
Q. Can I use other types of sausages?I prefer making this casserole with thick beef sausages. However, you can use pork, chicken, plant-based… whatever you prefer. If using thin sausages, boil for only three minutes and bake for about 40 minutes.Q. Can you freeze sausage casserole?Yes, it freezes well in portions. Thaw overnight in the fridge and re-heat in the microwave or a saucepan.
