Creamy Mushroom Potato Dauphinoise

Potatoes are comforting, filling and delicious. Mention potatoes and I'm in.

Yes I'll happily have them baked, boiled, roasted or mashed. Any way you want to cook them, I'm happy to eat them.

Dauphinoise is originally a layered potato dish made with creme fraiche. 

It was created in the region of Dauphine in South-East France. 

These days we mostly make it with cream rather than creme fraiche and I've taken this a step beyond that by using a creamy mushroom soup as my sauce for a really mushroomy hit.

You may be surprised to hear that nearly all of this recipe is made using frozen ingredients. Iceland challenged me to dip into their freezers and create a dish so I went freezer diving.

I use Iceland regularly. There's a store downstairs from the library I work in, so it's really handy. I pick up basics like bread, fruit and vegetables, pizza and the occasional bottle of wine. 

I never really go into the freezers for a look. Mad, isn't it? Come on Jac the name is Iceland, it's full of freezers, it's obviously what they specialise in.

I assumed their freezers would be filled with lots of meaty things, a few bits of veg and pizza, but nothing much for veggies or vegans. How wrong I was.

Here are a few of the highlights:

  • Piri Piri Sweet Potato Burgers (x2) £1.50
  • Zesty Bean Quinoa (500g) £1.50
  • Couscous with Vegetables (500g) £1.50
  • Creamy Spiced Lentils (500g) £1.50
  • Mushroom Risotto (700g) £1.50
  • Bulgur Wheat in Lemon & Mint Dressing (500g) £1.50
  • Classic Borlotti Beans and Pasta Soup (500g) £1.50

Lots of veggie ideas for quick midweek meals that are kind to the bank balance. 

I was also surprised and delighted to see they sell frozen herbs and curly kale. 

Those are going to be regulars on my list. I use a lot of fresh kale, but this will be much fresher as it hasn't done all the travelling and sitting on shelves my bagged kale has.

For my dauphinoise I used frozen crispy sliced potatoes, frozen mushroom soup, frozen parsley, fresh mushrooms and grated mozzarella, all from Iceland. 

I intended to include kale in this dish, but I forgot. The bag of kale sat beside me on the counter top and I still forgot to add it. I remembered as I was popping my dish in the oven. DOH! 

Do add a handful of kale to your mushroom sauce.

For a vegan option I would make up Colman's Parsley Sauce Mix (also from Iceland) with unsweetened soy or nut milk and use it instead of the mushroom soup, then top the dish with chopped salted cashews instead of mozzarella for a lovely crunchy topping. 

Still utterly delicious but quick.

  1. I'd say yes to this meal 10/10 times!

    1. Me too John, I'm a aucker for potatoes and mushrooms

  2. Wow, this is so clever!! I love the idea of using only frozen veggies and soup. It's an amazing quick meal to prepare on a very busy day. I will share it on twitter. x

  3. Yum! I've just visited my local Iceland for the first time and couldn't believe the choice for veggies - definitely giving this one a go for a quick weeknight supper.

  4. Presentation is wonderful, I bet it's yummy too!
    Have a nice day

  5. I love dauphinoise - had no idea it was originally made with creme fraiche. I always use cream! This is so clever though - I love using the soup for the sauce. Genius!

  6. Oh frozen potato slices. I didn't know there was such a thing. I love Dauphinoise, but it is such a faff slicing all those potatoes. This sounds delicious and even more so with the kale.

    1. It certainly saved time. I'don't still make it from scratch but this is great for midweek meals.

  7. This was one of my favourite dishes when I was a kind, as it's just so comforting. I was very impressed with the new Iceland range too.

  8. This sounds like great comfort food - and so easy with frozen produce!

  9. What a gorgeous dish! As much as we used Iceland, I dunno why I never realized freezers were what they were famous for! However, I have been into their freezers before, mostly on holiday, to stock up on things for the week.

    I love that you have a vegan option on this - what a good idea!

    1. Well I always have to cater for Graham too Tanita, somainly we eat vegan, but sometimes I make two dishes, the second a slight variation on the first.

  10. oh yes this... I would like to snuggle in under the layer of cheese and mushroom please xx

  11. I was searching for a dauphinoise recipe and came across this one. Looking forward to trying it and glad to have found your blog. E
