Winter Squash Soup with Fried Sage Leaves

This roasted winter squash soup is a quintessential vegetarian dish that perfectly captures the earthy, mellow flavours of the colder months. By roasting the squash alongside whole garlic cloves, you develop a deep, caramelised sweetness that provides a sophisticated base for the savoury herbs. The addition of aromatic thyme and parsley creates a wonderful depth of flavour, while the final flourish of crispy fried sage leaves adds a professional, textural contrast to every spoonful.

Ideal for a comforting weekend lunch or as an elegant starter for a seasonal dinner party, this versatile recipe works beautifully with butternut, acorn or kabocha squash. Serving the soup with a scattering of salty Fontina or Pecorino cheese adds a creamy richness that balances the sweetness of the vegetables. It is a healthy, homemade alternative to shop-bought versions that the whole family will enjoy.

Ingredients for Winter Squash Soup with Fried Sage Leaves

  • 2 1/2 to 1.4kg winter squash

  • 60ml olive oil, plus extra for the squash

  • 6 garlic cloves, unpeeled

  • 12 whole sage leaves, plus 2 tablespoons chopped

  • 2 onions, finely chopped

  • Chopped leaves from 4 thyme sprigs or 1/4 teaspoons dried

  • 1/4 cup chopped parsley

  • Salt

  • freshly milled pepper

  • 1.9L water or stock

  • 120ml Fontina, pecorino, or ricotta salata, diced into small cubes

Preheat the oven to 191°C. Halve the squash and scoop out the seeds. Brush the surfaces with oil, stuff the cavities with the garlic, and place them cut sides down on a baking sheet. Bake until tender when pressed with a finger, about 30 minutes.

Meanwhile, in a small skillet, heat the 60ml oil until nearly smoking, then drop in the whole sage leaves and fry until speckled and dark, about 1 minute. Set the leaves aside on a paper towel and transfer the oil to a wide soup pot. Add the onions, chopped sage, thyme, and parsley and cook over medium heat until the onions have begun to brown around the edges, 12 to 15 minutes. Scoop the squash flesh into the pot along with any juices that have accumulated in the pan. Peel the garlic and add it to the pot along with 1 1/2 teaspoons salt and the water and bring to a boil. Lower the heat and simmer, partially covered, for 25 minutes. If the soup becomes too thick, simply add more water to thin it out. Taste for salt.

Depending on the type of squash you've used, the soup will be smooth or rough. Puree or pass it through a food mill if you want a more refined soup. Ladle it into bowls and distribute the cheese over the top. Garnish each bowl with the fried sage leaves, add pepper, and serve.
