Sweet Potato and Blue Cheese Dauphinoise

Sweet Potato and Blue Cheese Dauphinoise

This Sweet Potato and Blue Cheese Dauphinoise is my most recent sweet potato creation, but definitely one of my best. Decadent and creamy, this vegetarian friendly dish would make a lovely addition to your Christmas lunch, either as a side or as a main dish for the veggie's in your house. I also have it on good authority it's a very 'hygge' dish. Hygge (pronounced 'Hue Gah') is a Danish word (although the Norwegians argue it's originally from them), that's very 'in' at the moment. It basically means creating an elevated state of cosiness....think people close to you, woolly socks, warm fire, candlelight...and most importantly comfort food. This dish most certainly ticks the comfort food box!

The blue cheese and Parmesan contrast so well with the sweetness of the potatoes and the creaminess of the sauce and I would be more than happy to eat a bowlful of this for dinner with nothing else. In fact, I did just that with the leftovers. I used some award winning Blacksticks Blue cheese in this recipe, which was kindly sent to me to try, but stilton would work well too. If you have lots of cheese hanging around from Christmas Day, why not use a mixture of cheeses and serve this up for your boxing day leftover feast?

Another bonus of this recipe is that it's made in one pan, so less washing up during the busy festive period. The dauphinoise recipes I've made in the past usually require you to part cook the sliced potatoes in the cream on the hob, before spooning into an ovenproof dish for the oven. Not this one! One shallow casserole dish is all you need.

I hope you enjoy this sweet potato dauphinoise as much as we did!

Sweet Potato and Blue Cheese Dauphinoise


  1. Slice the sweet potatoes as thinly as you can. If you have a mandolin use that.
  2. Try this dish with different herbs. Sage and rosemary would work well.
  3. Use leeks or shallots instead of onion if that's what you have.
  4. If you weren't serving this as a vegetarian dish, add some leftover Christmas ham.

No Bake Zingy Lime Crumb Pie

This No-Bake Zingy Lime Crumb Pie is going to be my go to dessert this summer. A zingy lime cream encased in a sweet biscuit crumb - much like a no bake cheesecake...but better! It's seriously yummy and will happily sit in the fridge for a couple of days so there's no need to scoff it all at once if you don't want to 😜. It's quite rich too so the recipe made in a 20cm springform tin will easily feed 8 - 10 people, the perfect size for a family gathering or summer BBQ.

TOP TIPS FOR MAKING NO-BAKE ZINGY LIME CRUMB PIETry using ginger nut biscuits instead of digestives for a more grown up taste.For a 'fancier' dessert, pipe some whipped double cream around the edge of the pie and decorate with slices of lime.I whip the condensed milk, lime juice and double cream with a hand held electric whisk but you can do it by hand if you want to - it will give you a good arm workout!You can make the Zingy Lime Crumb Pie up to 3 days before you need it so it's a great ma…

Honey and Peanut Butter Flapjacks

These flapjacks are now my official weekday grab and go breakfast. I make a big batch on Sunday evening and I'm all set for the week. Oddly I don't really like peanut butter but it works well in this recipe. You can always substitute it for an extra 100g of ordinary butter if you wanted. A handful of raisins makes a nice addition too.
