Vegan scalloped potatoes nut-free

Ah, side dishes. They have a bit of a negative reputation in the vegan community. Mostly because we often associate them with the thing one has to eat when there are no other options. And those side dishes are often of the bland salad variety, or, at best, crusty bread.

 

But, fear not. Vegan side dishes can be so good, they almost overshadow the main. I mean, I can’t imagine a Christmas without at least one potato-based dish on the table. Sure, normal roast potatoes are great. But even better? Yep, you guessed it. Vegan scalloped potatoes come to the rescue. I would say that they are even good enough to eat as a main course!

Nut-free vegan scalloped potatoes

As I mentioned in my vegan baked mac and cheese recipe, a lot of vegan recipes that involve a creamy sauce require a blender and/or cashews. If you don’t have a blender and/or don’t eat cashews? That can prove a struggle.

So, I wanted to create a nut-free scalloped potato recipe, that doesn’t compromise on flavour. That means no coconut either. Sounds like the boundaries are pretty strict, but I myself was surprised at how well just ordinary plant based milk did the trick. You can use whatever variety you prefer (just ensure it’s unsweetened), but my favourites are soy milk and oat milk. They are both super creamy and have a great subtle flavour.

The result? Creamy, flavourful goodness that you won’t be able to get enough of. The waxiness of the potatoes pairs SO well with the rich sauce. The sauce has a umami undertone and the chives add a little splash of colour. But you can, of course, emit them or replace with spring onions.

Ingredients and substitutions

The ingredient list is pretty short and simple. You will need:

  • Cornstarch. Arrowroot powder or tapioca work too.
  • Plant based milk such as soy milk or oat milk.
  • Nutritional yeast. This is key for achieving a cheesy flavour! If you want to, you can use grated vegan cheese instead.
  • Fresh garlic, or garlic powder.
  • Mustard. Ensure vegan and gluten-free.
  • Hot sauce. This is optional, but keep in mind that it won’t make the dish spicy – just enhance the cheesiness.
  • Good quality sea salt.
  • Fresh lemon juice.
  • Fresh chives. 
  • Waxy potatoes, sliced very thinly. The Russett potato variety works particularly well.

How to make dairy-free scalloped potatoes

First, preheat the oven to 180 degrees C/350 F.

Next, add the cornstarch and 1/4 cup of the plant based milk to a saucepan and stir over a medium heat to dissolve. Then, proceed to slowly pour in the rest of the milk, around 1/2 cup at a time, and stir for around 30 seconds, until the sauce begins to thicken before pouring more.

When around 1/2 of the plant based milk had been added, stir in the nutritional yeast, garlic, mustard, hot sauce and salt.

Right at the end, remove the sauce from the heat and stir in the lemon juice together with the fresh chives.

In a rectangular or oval baking dish, add a layer of sliced potatoes, followed by a layer of the sauce. Continue layering until you reach the top of the dish, and finish off with a layer of the sauce.

Cover with a sheet of aluminium foil and bake in the preheated oven for 50 minutes. Then, carefully remove from oven, remove the foil and bake for a further 20 minutes.

How to store scalloped potatoes

You can make these scalloped potatoes ahead of time. Bake with the aluminium foil, then place in the fridge, covered tightly. When you are ready to serve, place back in the oven, uncovered, for around 30 minutes. I wouldn’t recommend storing them for longer than around 3 days.

You can also freeze any leftovers for up to a month.

Tips for the best vegan scalloped potatoes

  • Slice the potatoes thinly and evenly, using a mandolin to achieve even slices.
  • Avoid adding too much salt, as this will mask the earthy and creamy flavour of the dish.
  • Use a waxy potato variety for the best texture and flavour.
