Why you will love these Scalloped Potatoes

  • They’re healthy! Packed with real-food ingredients, these gluten-free scalloped potatoes and whole30 complian and dairy-free but still taste rich and creamy.
  • Two recipes in one! It starts with a simple Tom Kha Soup recipe – you could easily just add protein and have a yummy soup, or make a double batch of the broth to have both!
  • It’s such a comforting recipe. The combination of potatoes, coconut milk, and cashews is so comforting and filling – it feels very decadent.

How to make Tom Kha Gluten-Free Scalloped Potatoes

  1. Make your broth first. Sauté the onions, then the rest of the fragrant veggies/spices.

2. Add one can of coconut milk, mix until the cream has melted. Repeat with 2nd can of coconut milk, before adding cashew cream. Stir until well combined. Let simmer for 10 mins, or longer, to really bring out those zesty flavours.

3. Slice potatoes into 1/2cm thick pieces. Layer potatoes in baking dish, then broth, and repeat 2 more times, or until all the potatoes and broth are in the pan.

4. Cover with aluminium foil and bake for 60 mins, until tender.

5. Remove foil and bake for another 10 mins or until the top layer is golden brown.

Things to note.

  • Watch the soup as it simmers! Mine boiled over, oops.
  • Cut the lemongrass very finely – more fine than mine in the video – to avoid pieces that are more difficult to chew.
  • Add another chilli if you like the heat.
  • Salt! You’ll need more than you think – be generous.
  • Kaffir leaves can be found in your local supermarket’s spice section, in a regular spice jar (I found mine at Tesco, so it’s fairly common).
  • Lemongrass is in the fresh produce section, usually near packaged fresh herbs.
  • You could make this with sweet potatoes instead of yellow potatoes. It would pretty much be like a slightly spicy dessert to me at that point, yum!
  • How about trying mixed root veg? Parsnips, turnips, carrots, plus potatoes! A scalloped veggie rainbow =]
