Best cream alternative for dauphinoise potatoes please?

[Raera]

As above really. For recently diagnosed lactose intolerant guest who used to love them!
Or an alternative bake in the oven non-dairy potato side dish to go with roast lamb?
I've tried boulangere before and can never get them right-by the time they are cooked through they are almost burnt.
Thanks in advance

Do you cover the dish with foil? I cover with foil until the potatoes are almost done, then crank the oven up, remove the foil and give them another 20 minutes to brown.

Can't you just get lactose-free cream?

Stick can work and definitely cover.

I use Lacto free cream.

try looking up boulangere potatoes. Basically dauphinoise with stock not cream https://www.cookingwithcamilla.com/vegan-boulangere-layered-potato-side-dish/

argh, sorry, just seen you’ve tried Boulangere. Sorry!

You could experiment with invisible potatoes. Replace milk and butter with plant milk/stock. I’ve made it and it’s delicious.

Invisible potato cake looks lush!

Elmlea plant based double cream would work fine

A friend very kindly used lacto free milk/cream for me (I’ve never tolerated milk or cream) - I had the same reaction as if it was dairy! However I have no issues with plant based alternatives!

Yes, I've used this to make these before for my son who is allergic to milk. Works fine.

It truly is! I came across it first as a dessert, called pommes invisibles; it is incredible. I’ve also made it with pears which was even better.

Had the savoury one at christmas with parsnips and sweet potato. It’s such a versatile recipe can highly recommend it.

My daughter's work prefers flora vegan cream to elmlea, she is a chef.

Hassleback potatoes would be nice though with some rosemary for seasoning.

Oatly Creamy Oat works

Pommes boulangere. Uses stick and onions for flavour. Yummy!

Elmlea is the nicest dairy free cream I've found
