Creamy, warming for the colder months and so easy to make – slow cooker sausage and leek casserole is a family favourite here.
Sweetness from honey (I used Maille brand French mustard with added honey), warmth from mustard, leeks which melt away, a creamy sauce which you must mop up every last bit of!
You can serve it with mash, pasta, rice or crusty bread depending on the season.
We love it with mustard mash in the winter, or over pasta with the sausages cut into pieces.
Make it as I’ve done here with low-fat sausages and lighter creme fraiche and you’ve also got a comforting dinner which isn’t too heavy on the calories. Winning all round!
Slow cooker sausage casserole always goes down well in my house, I usually make two versions, a simple one which uses up any vegetables in the fridge or a venison sausage and borlotti bean one which is good for the depths of winter.
This honey mustard sausage and leek casserole is good for spring with its lighter flavours and light and creamy sauce made of chicken stock and creme fraiche.

I did this today and it was delicious. I used pork and leek sausages as I love leeks. I still added the leeks of course lol . Instead of creme fraiche I used double cream ( naughty me ) lol. I will definitely be making this again.
Thank you
