Ingredients & Substitutions
Potatoes: The star of the show, potatoes form the base of Dauphinoise potatoes. Opt for starchy potatoes such as baking potatoes or Maris Piper in the UK. If you are in the US, opt for Russet or Yukon Gold, as they have a higher starch content that contributes to a creamy texture when cooked.
Onion: Use 1 medium sized white onion for added flavour. While it is not a must, but adding the onion makes all the difference. I wouldn’t recommend using red onion as sub. You can leave it out.
Cream: It is the key ingredient that gives Dauphinoise potatoes their luxurious, velvety texture. You can also substitute part of the cream with milk or half-and-half if you prefer a lighter version.
Garlic: An essential flavour enhancer in Dauphinoise potatoes. Finely mince or crush fresh garlic cloves to infuse the cream with its aromatic essence.
Salt and Pepper: Seasoning with salt and pepper is crucial to enhance the flavours of the dish. Use kosher salt or sea salt and freshly ground black pepper for the best results.
Cheese: I love using mature cheddar cheese in my air fryer potato dauphinoise. You can switch it up and use Mozzarella cheese, Gruyere cheese, Parmesan or rRed Leicester cheese.
Optional ingredients – Adding bay leaf or thyme will add a delicate earthy and herby aroma to the dauphinoise dish.
Optional toppings – Chives, parsley or thyme can be used a topping. They will add a pop of green and fresh luscious flavours to the dish.

- Slice the potatoes into thin, 1/8 inch thick rounds using a sharp knife. Alternatively, you can use a food processor or mandoline slicer for even and precise cuts.

Sprinkle a generous amount of grated cheese on top of the cooked potatoes and bake for an additional 4-5 minutes, or until the cheese has melted and turned a beautiful golden brown.
