Ready In:




  • Preheat the oven to 400 F or 200 degrees C.
  • Place onions, rosemary and a bit of salt in a small saucepan and cover with 1 cup water.
  • Bring to a boil, then turn down the heat immediately.
  • Cover and cook, stirring once or twice, for about 15 minutes until the onions are very soft, uncoloured and most of the liquid has disappeared.
  • Meanwhile, peel the potatoes and cut into chunks.
  • Rinse and boil in lots of salted water.
  • Also, smear the sausages with oil, then place in a casserole dish and cook in the oven for about 30 minutes, turning half way through.
  • Finish the onion sauce by boiling hard if necessary to get rid of any extra water.
  • Discard the rosemary stalk, sift the flour over the top and stir.
  • Add the mustard and 1 cup of the milk.
  • Simmer gently for at least five minutes to cook the flour and make a thick, creamy sauce.
  • Make the mash by draining the potatoes, adding the remaining milk and butter and mashing until smooth.
  • Whip with a wooden spoon to make the mash light and fluffy, adding extra butter or milk if it's too thick.
  • Divide onto plates, top with the sausages and a generous spoonful of gravy.

    Mmmm! True comfort food. My husband can't eat pork, so I used beef sausages instead. Still stasted good. Its easy to make. I served it with peas and honey/sesame carrot and it was wonderful. Do try it.

    Easy and flavorful - I think the choice of "bangers" have a lot to do with it, too. We use Johnsonville's Irish Garlic Sausage and slice it since it comes in rather large links. DH requests this dish about once a week. Thanks for the great recipe.

    I've used this recipe for its onion gravy several times, so thought I ought to weigh in. I just simmer kielbasa for 20 min. and use a good instant potato mix, but the gravy makes it special! There's only two of us eating it so I use 1 onion. We love it, thanks!

    Did I do something wrong? The sauce was virtually flavor-free, I don't get it. I used good quality ingredients, but the tastebuds of both my husband and I must be out of whack. I've uploaded a picture... does it look right to you?

    I am not really a sausage fan but will have them once in awhile as my husband and son love saying that when I do have them I like to serve them with mashed potatoes...I did like the creamed onion gravy with these..(I tend to make a brown onion gravy) this was something a little different. Thanks for sharing.


This is a picture of me and my husband in Portugal, climbing up above the clouds with our bikes. Right now we are travelling around the world on our bicycles, so I only pop onto Zaar occasionally, when internet connections and time allow me to. If I don't reply to a message about one of my recipes, now you know why! Our trip may take several years so if it's urgent, it's probably better for you to post in the forums ;) Good food is really important to me -- I am happy to pay extra for food that I feel is produced in a sustainable and ethical way and always try to eat using seasonal produce. When we were in the UK we rarely shopped at supermarkets, trying instead to favour small producers, although we were very lucky in that we lived in London and there was lots of choice. We also were fortunate enough to have a weekly organic veg box delivered to our door, filled with so many lovely vegetables for very little money. It really opened my horizons in terms of the variety of vegetables I eat. If you're in the UK, check out Riverford for a box supplier as they're amazing! When I'm not eating I love to take pictures and travel with my husband. <img src="">
