Sweet Potato and Parmesan Tart

This sweet potato and Parmesan tart proves that a handful of simple ingredients can create something surprisingly elegant.

Ingredients · Servings 4
  • 5 medium sweet potatoes ((about 800-900 g/ 2 lb total))
  • a little butter (for greasing the dish)
  • 300 ml heavy cream
  • 2 eggs
  • 100 g grated Parmesan cheese
  • 1/2 teaspoon freshly ground black pepper
Method · 1 h 5 min
  1. Preheat the oven to 180°C (356°F).
  2. Peel and wash the sweet potatoes, then slice them into very thin ribbons using a vegetable peeler or mandoline.
  3. Grease a 18-20cm (7-8 inches) round baking dish with butter.
  4. Arrange the ribbons upright in the baking dish, starting at the outer edge and working inward in a spiral pattern until the dish is filled.
  5. In a bowl, whisk together the eggs, cream, Parmesan, and black pepper until well combined.
  6. Pour the mixture evenly over the sweet potatoes, making sure it seeps between the layers.
  7. Sprinkle a little extra Parmesan over the top, if desired.
  8. Bake for 45–55 minutes, or until the sweet potatoes are tender when pierced with a knife and the top is golden brown.
  9. Let the tart rest for 10 minutes before slicing and serving.

As it bakes, the sweet potatoes become tender while the Parmesan adds a savory depth that balances their natural sweetness. The result is somewhere between a tart, a gratin, and a crustless quiche. It’s a dish that’s just as welcome on a brunch table as it is alongside a salad for dinner. It’s easy enough for a weeknight meal but impressive enough to serve when guests are coming over.
