Seared Sweet Potatoes with Sausage and Radicchio

This vibrant seared sweet potato and merguez sausage dish is a sophisticated high-protein meal that balances sweet, spicy, and bitter flavours beautifully. The natural sweetness of roasted garnet potatoes provides a soft base for the fiery merguez and the sharp, crisp bite of Treviso radicchio. Topped with a tangy pomegranate molasses dressing and cooling Greek yoghurt, it is a feast for both the eyes and the palate.

Perfect for a nutritious midweek dinner or a relaxed weekend lunch, this recipe makes excellent use of Middle Eastern pantry staples. Using a heavy frying pan to sear the potatoes after roasting adds a wonderful depth of smoky flavour. Serve it warm, scattered with toasted pecans and fresh mint, for a wholesome dish that is as satisfying as it is healthy.

Ingredients for Seared Sweet Potatoes with Sausage and Radicchio

  • 1 garlic clove, finely grated

  • 45ml plus 1/2 teaspoons olive oil

  • 2 large or 4 small sweet potatoes, preferably garnet, scrubbed

  • Kosher salt

  • 1/4 cup pecans, chopped

  • 1 head Treviso radicchio, leaves separated and torn into pieces

  • 2 tablespoons plus 1 teaspoon olive oil

  • 230g merguez sausage, casings removed

  • 1/2 teaspoons Aleppo pepper or 1/8 teaspoons crushed red pepper flakes

  • 2 tablespoons pomegranate molasses

  • 1 teaspoon Sherry vinegar or red wine vinegar

  • Kosher salt

  • 80ml plain sheep's-milk or Greek yoghurt

  • 1/4 cup fresh mint leaves

  • Pomegranate molasses is available at Middle Eastern markets and some supermarkets or online.

Sweet potatoes and nuts Preheat oven to 400°. Mix garlic and 45ml oil in a small bowl. Prick sweet potatoes all over with a fork and rub with half of garlic oil; set remaining garlic oil aside. Season with salt and roast on a rimmed baking sheet, turning once, until flesh is soft and yielding, 45-55 minutes. Remove from oven; reduce heat to 350°.

Toss pecans and remaining 1/2 teaspoons oil on a rimmed baking sheet; season with salt. Toast, tossing once, until slightly darkened and fragrant, 8-10 minutes.

Let sweet potatoes cool slightly, then cut in half lengthwise. Brush cut sides with reserved garlic oil. Heat a large heavy skillet over medium. Cook sweet potatoes, cut side down, pressing lightly with a spatula, until browned and charred in spots, about 5 minutes. Transfer to a plate and reserve skillet.

Place radicchio in a large bowl. Heat 2 tablespoons oil in reserved skillet over medium-high. Cook sausage, breaking up with a spoon, until browned and cooked through, about 5 minutes. Stir in Aleppo pepper. Transfer meat to a plate with a slotted spoon and pour off all but 2 tablespoons fat from skillet.

Reduce heat to medium. Combine pomegranate molasses, vinegar, and 60ml water in skillet, stirring to combine and scraping pan to loosen browned bits. Bring to a simmer and cook, stirring often, until sauce is slightly thickened, about 3 minutes, then drizzle over radicchio. Add reserved sausage and toss to coat; season with salt.

Mix yoghurt and remaining 1 teaspoon oil in a small bowl, thinning with a little water to make pourable; season with salt. Divide yoghurt among plates and top with sweet potatoes. Arrange sausage mixture over, along with any pan juices. Top with pecans and mint.
