Low-FODMAP Smashed Salt & Vinegar Potatoes; Gluten-free, Dairy-free

Print Friendly Version
low fodmap salt and vinegar potatoes

I read this recipe in a magazine at the salon and I knew it would be an awesome (modified) addition to my low-FODMAP side dishes. A gourmet twist on traditional roasted potatoes, these low-FODMAP smashed salt and vinegar potatoes are guaranteed to complement any low-FODMAP dinner.

This low-FODMAP Smashed Salt and Vinegar Potato recipe results in super crispy edges, with soft potato centers and a tang of vinegar.  Sort of like salt and vinegar chips, only better for you.

I have always loved vinegar on my potatoes…its the growing up in Canada thing 😉

  • 5 TB kosher salt, divided, plus more for sprinkling
  • 2 TB unsalted butter (for non-vegan version) or olive oil
  • 1/2 tsp freshly ground black pepper

  • 2 cups ice


  • Combine potatoes, 1 cup vinegar and 1 TB salt in a large saucepan over high heat
  • Add water to cover potatoes by 1 inch

  • Bake about 30-40 minutes until crispy and golden
