Course: Appetizer, Main Course
Servings: 4


  • 1 sweet potato/s (large) peeled and diced into approx. 1.5cm cubes
  • 2 tbsp butter, ghee or olive oil -melted
  • 1 tsp ground cinnamon
  • 375 g Carême All Butter Puff Pastry (contains no vegetable oil or nasty additives). The new wholemeal spelt is delicious too.
  • 1 red onion/s (large) peeled and sliced
  • 1 tsp rice malt syrup
  • 1 tbsp aged balsamic vinegar
  • 100 g feta cheese -or goat feta, crumbled
  • Sea salt and freshly ground black pepper -to taste
  • Handful rocket leaves - to serve (optional)


  • 2 tbsp olive oil
  • 1 tbsp aged balsamic vinegar


  • Preheat your oven to 200℃/395℉ (fan-forced).
  • Toss your diced sweet potato in 1 tablespoon of the fat or your choice and cinnamon.
  • Arrange in a single layer on a baking dish and bake for approx. 15-20 minutes or until cooked through.
  • Whilst the sweet potato is baking, cook your onion slices in the remaining tablespoon of fat over a low heat for 10 minutes (or until they become opaque). Add the sugar and 1 tablespoon of balsamic vinegar and cook for another 10 minutes or until the onion starts to caramelise.
  • Once the sweet potato is cooked through, remove from the oven, set aside enough sweet potato for baby and season the rest.

Babies meal

  • You can mash or puree the sweet potato with a little bone broth mixed though or serve as is if you are baby-led-weaning. Store in an airtight glass container or jar in the fridge.

Family meal

  • Assemble your tart by spreading the middle of the puffed pastry (leave a 2cm border) with the onion, then top with the sweet potato and feta. Bake for 15-20 minutes or until your puff pastry is golden brown.
  • Mix the dressing ingredients together in a small jar or bowl.
  • Remove the tart from the oven, top with the rocket and drizzle with the dressing.


  • Serve immediately with a leafy green salad.


  • Store in an airtight container in the fridge. Re-heat in the oven to crisp the pastry.



Choose coconut oil for your fat and replace the feta with a vegan cheese. You'll also need a dairy-free puff pastry. 


Choose ghee or butter as your fat.


Choose the olive oil to caramelise your onion. Choose a vegan pastry and replace the feta with a cashew cheese.
