Sausage and Potato Casserole, a cosy dinner recipe that is family-friendly and goes down well all year round. It's cheesy and hearty, with a homemade herby gravy that gives it a wonderful touch, and it's on the table in way under one hour.

Comfort food doesn't have to be enjoyed only in the cold season, on the contrary. A hearty meal is surely appreciated after a long day at work, or on a rainy day, and it always puts a smile on your face.
Potatoes and sausages are staple foods that you can never go wrong with, one of our favourite dish that we always go back to is the one and only Bangers and Mash with Onion Gravy.
The combo just works so well, it's nutritious and soothing, and you know that even the pickiest eaters will not be able to resist. And this potato and sausage casserole is another good example why the combo works.
The herby onion gravy adds a lot of flavour, so that's one step I would not skip, then it's the cheesy goodness that you get from the cheddar cheese, although any other cheese would work as well.
Cheesy, bubbling hot, layers of flavour and goodness, that's one dish you can't possibly miss, you will 100% love it! And definitely one to add to your Father's Day Menu or your Family-Friendly Dinner Bakes.

Expert tips
The potatoes have to be cooked through before you add the rest of the ingredients to them, as they won't have time to cook in the oven otherwise.
Cooking the sausages beforehand is also important, or the casserole will end up being too greasy and too heavy if the sausages are added raw.
Feel free to add more cheese if you wish, or any swap the cheddar cheese for any other cheese - the more comforting, the better!
