Creamy Potato Bake with oat milk

Creamy Potato Bake with oat milk

A potato bake is a humble but tasty side dish or this could accompany greens for a  Meatless Monday dinner. Potato bake is super popular worldwide. This recipe is  a creamy sauce made with oat milk and cream cheese. If you didn't want the cream cheese you could easily make a simple béchamel sauce or replace the cream cheese and grated cheese in this recipe for non-dairy or vegan cheese to make this potato bake a vegan recipe. For ease I prefer to use new or washed potatoes but you could swap this out for whatever potatoes you may have on-hand. Serves 2 you can double this for a family size.

Sue Maree P Tips

  • Potatoes – no mandolin, pre boil potatoes for 15-20mins until slightly soft then slice
  • Cream cheese – use other types of cream cheese or if you prefer no cream cheese then add 200ml more milk but double the cornflour and butter
  • Gluten free – leave off the crunchy bread topping
  • Vegan – replace cheese for non dairy cheese and use nutritional yeast flakes instead of parmesan cheese.
  • Prepare for a few days prior – prepare the first 6 steps then cover with lid or plastic wrap and leave in the refrigerator overnight or for a few days then bake.
