This is another dish that’s just crying out to be sorted: vegan dauphinoise potatoes gratin. It’s rather decadent I know, but hey, who’s checking up! My mum certainly isn’t. I did a quick look-up on line and found a few candidate non-vegan recipes, then just did a bit of judicious substitution.
Fortunately there are now quite a few vegan cream subsitutes available on the market. Oatly, Elmlea or Alpro work well. Whilst oat milk makes a great milk substitute as it doesn’t curdle when cooked. I added some veg stock, and next time, I think I’ll add a little nutritional yeast.
This dish is one of those where a decent slicing machine really comes in handy. It has to be said, a Graef slicer makes quick work of slicing the potatoes. With a knife it would a long job, and getting the slices thin enough would be a nightmare. It’s literally no problem with a Graef slicer.
I’ve tried various methods, but simmering the potato slices in the cream mixture first is deffo the way to go. Give them around 8 minutes and it means they cook beautifully in just 30 minutes in the oven.
Sprinking a bit of vegan gruyere cheese on top and a little black pepper too really finishes it off well. You could also add a sprinkling of smoked or ordinary paprika, and maybe even some breadcrumbs. I also added a few dobs of vegan butter as a final touch.
This dish goes so well with lasagne, pastitsio, spinach & lentil pie etc. Vegan dauphinoise potatoes gratin – what’s not to like! I also like it with a side of my wholemeal garlic bread Yum Yum!
