Pecan Crusted Sweet Potato with Sour Cream

Food blogger Jules Clancy of Stone Soup recommends being generous with the seasoning to make these sweet potatoes taste like dessert. Make this dish ahead of time to avoid the five common Thanksgiving mistakes that Jules also explains how to avoid as well.



  • 1 large sweet potato
  • 100g (3.5oz) pecans
  • 2 large handfuls freshly grated parmesan cheese
  • small bunch thyme
  • 30omL (1.5 cups) sour cream, to serve


  1. Preheat oven to 200C (400F).
  2. Scrub sweet potato and slice into 8 rounds, about 1cm (1/3in) thick. Discard the small ends.
  3. Place slices in a single layer on a baking tray lined with baking paper. Drizzle generously with olive oil.
  4. Finely chop the pecans leaving a few chunky bits. Combine pecans with cheese and about 1 tablespoon thyme leaves and 3-4 tablespoons of olive oil to moisten. Season.
  5. Divide pecan mixture between the sweet potato rounds, pressing gently but not to compact it too much. Sprinkle with remaining thyme sprigs.
  6. Bake for 40-50 minutes or until the crust is deeply golden and the sweet potato is tender. Check after 30 minutes and if it’s browning too quickly cover with some foil.
  7. Serve hot with sour cream passed separately so everyone can add their own.



  • Budget – replace all or part of the pecans with coarse soft breadcrumbs and use a cheaper parmesan style cheese such as grana padano
  • Vegan / Dairy-Free – replace the cheese with soft breadcrumbs and be more generous with the olive oil. Serve with a tahini sauce (equal parts lemon juice, tahini and water) instead of the sour cream
  • Pumpkin / Winter Squash – replace the sweet potato with thin slices of butternut pumkin (squash)
  • Different Nuts – swap the pecans for almonds, brazil nuts or walnuts. Or choose a mixture of these
  • Carnivore – serve draped generously with OR serve as a side to a glazed ham
  • Less Decadent – serve with a good quality natural yoghurt instead of the sour cream
