Plant-Based Cranberry and Onion Tart With Fresh Rosemary

If you’re looking for a centre piece for your Thanksgiving meal, or if you’re having friends round for dinner, try this delicious Plant-Based Cranberry and Onion Tart With Fresh Rosemary.

I’ve served it here with roast potatoes, roast garlic, sweet carrot batons and Brussel sprouts with toasted caraway seeds.

For the carrots, take 500g/17oz carrots, washed and cut into even sized batons and put into a pot with four tbs honey and 500ml/17oz vegetable stock. Simmer for 15 minutes then increase the heat so the remaining stock evaporates. The carrots should be nice and shiny. Just before serving sprinkle two tablespoons of toasted sesame seeds over the carrots.

For the Brussels sprouts, take 500g/17oz washed and cut into half sprouts, steam them until tender, but not mushy. Toast two tablespoons of caraway seeds in a dry pot for a few minutes them add to the Brussels sprouts with the juice of a fresh lemon.

You can also roast the sprouts for 15 minutes in an oven proof roasting tin. Just put a few tablespoons of water in the tin with the sprouts, throw in some garlic cloves and two tablespoons of caraway seeds. Once cooked, squeeze the juice of a whole lemon over the sprouts and serve.

Course Main Course
Servings 5


  • Pot
  • Wooden spoon
  • Baking tray
  • Greaseproof paper
  • Sharp paring knives
  • Pastry cutter or small saucer


  • 320 g ready made ready rolled puff pastry, thawed if frozen. Make sure it's labelled vegan friendly.
  • 550 g onions thinly sliced. I used a mandolin
  • 8 heaped tablespoons cranberry sauce - I make my own. Click above for the recipe
  • 3 tablespoons chopped fresh rosemary
  • rosemary for decoration
  • plant-based milk such as almond or brown rice


  • Turn the oven to 180 celsius or 350 Fahrenheit. Meanwhile, add the sliced onions to a pot containing 4cm/2" of cold water and cook over a low heat for 20-30 minutes stirring frequently until the onions are soft and they begin to caramelise. Keep adding more water if the water evaporates. You may have to do this three or four times. This helps to makes the onions lovely and soft and breaks down the natural sugars in the onion.
  • Put the puff pastry on a flat surface like an oven proof baking sheet. Use a pastry cutter or saucer and cut out four circles, each measuring 12cm/5" in diameter.
  • Turn over the edges of each and pinch them to help them retain their shape. Prick the bases with a fork and using a pastry brush, brush them with some plant-based milk such as almond or brown rice.
  • Line the tart with baking parchment and fill it with ceramic baking beans or dried pulses. This helps to stop the base becoming soggy and is known as 'baking blind'.
  • Put the tarts into a hot oven for five to ten minutes.
  • Remove from the oven and discard the baking parchment and ceramic baking beans or dried pulses.
  • Divide the cranberry sauce equally between the four pastry circles. Top with the caramelised onions and sprinkle the freshly topped rosemary over the top of the four tarts.
  • Bake for 15-20 minutes until they're well risen, then serve with your choice of vegetables and potatoes.
  • Brush the edge with some plant based milk then bake for 15-20 minutes until well risen.
