Prawns and Roasted Fennel Ditalini

This prawn and roasted fennel ditalini is a sophisticated yet simple high-protein dish that makes the most of fresh, aromatic flavours. By roasting the fennel until tender and sweet, then finishing the dish with a quick prawn stock made from the shells, you create a deep savoury base that beautifully coats the whole-wheat pasta. The addition of crushed fennel seeds and zesty lemon provides a bright, Mediterranean finish that feels both light and satisfying.

Ideal for a nutritious mid-week supper or a relaxed weekend lunch, this recipe uses whole-wheat ditalini to boost the fibre content without compromising on texture. The combination of succulent prawns and caramelised vegetables provides a balanced, protein-rich meal that is as healthy as it is delicious. Serve it warm with a scattering of fresh fennel fronds for a truly professional touch.

  • 450g (16 to 20) extra large prawns, shells intact, thawed if frozen

  • 1 teaspoon fennel seeds

  • 1 teaspoon salt, preferably sea salt, divided

  • 1/2 teaspoons freshly ground black pepper

  • Grated zest of 1 lemon (1 julienned strip for garnish, optional)

Heat oven to 232°C. Shell prawns, but keep tails intact, if desired; reserve shells. In a small pan over medium heat, toast fennel seeds until golden brown, 5 minutes; crush. In a bowl, toss prawns with fennel seeds. In same pan, bring 240ml water to a boil with 1/2 teaspoons salt and reserved shells; reduce heat and simmer, partially covered, 30 minutes. Remove and discard shells; simmer until stock reduces by half, 5 minutes. In a roasting pan, place sliced fennel, garlic, oil, pepper and remaining 1/2 teaspoons salt; toss. Roast until fennel is tender, 20 minutes. Stir in prawns, stock and zest; roast until prawns are just cooked through, 5 minutes. Cook pasta as directed on package until al dente. Drain pasta, reserving 240ml cooking liquid. Add pasta to roasting pan; roast until pasta is completely cooked, adding reserved liquid a little at a time and stirring to reach desired consistency, 5 to 10 minutes. Serve garnished with julienned zest and fennel fronds, if desired.
