I rarely give a recipe 5 stars, but this is such a tasty and impressive dish for such a simple recipe! I left the new potatoes whole as they were quite small. The only thing I would change is to leave the onion in bigger chunks - the recipe says to slice them finely, but then they burn in the oven.

These are our new favourite roast potatoes! I'm not usually a fan of mustard but here the mustard counteracts the sweetness of the red onion perfectly. I served them with sausages and vegetables when we had friends over and they were so popular all our friends asked us for the recipe! I made I partly prepared the potatoes the night before (parboiled abs mixed with the oil, onion and mustard) then put in a covered dish in the fridge. All I had to do the next day was roast them and they were absolutely delicious. Highly recommended.

Fantastic! Used a bit less mustard and roasted for about 50 minutes.

Gorgeous. Followed the recipe exactly (unusual for me!) and they turned out perfectly. Will be serving these with lots of things - it looks as if you've made a real effort, but it's so easy!

Love these! So delicious and the red onion becomes caramelised during the roasting. I am not a big fan of large chunks of onion but this is absolutely lovely with the mustard bringing it all together.

I loved this, the red onion was especially sweet, i think this is a great alternative for a roast pots, sadly my traditionalist boyfriend did not agree but he didn't leave any on his plate! We had it with the tarragon chicken but felt it was too many flavours.

Forgot to say that I did this with the usual roasting potatoes, rather than new potatoes - just cut them in half.

Forgot to rate it..

They never turned out crispy (I think they had to be in the oven for much longer for that to happen), but the mustard was a nice twist. It was not empowering at all - which is fine because I don't love mustard!

As per other comments, really easy to make and delicious! Especially with the Tarragon Chicken recipe.

these were good but if i was serving them with a dish which had its own sauce (like the tarragon chicken) then i would reduce the amount of mustard as it was a little over powering. but if i serve them with sausages, which works really well, then the amount of mustard in the recipe works fine.

These potatoes are amazing! Really easy to make and really tasty. I dont usually like mustard but its quite subtle. Will be making again.

Absolutely gorgeous!! I didn't have enough wholegrain mustard so I used half wholegrain and half dijon and it was a lovely dish. Me and my other half would have been quite happy with just a plate full of the potatoes!
