Head-On Prawns with Chilli, Garlic, and Parsley

These garlic and chilli grilled prawns are a striking addition to any outdoor feast or light midweek supper. By grilling the prawns in their shells, the delicate meat stays incredibly succulent while absorbing charred, smoky notes from the heat. The simple dressing of extra virgin olive oil, pungent garlic, and a hint of red chilli flakes provides a punchy, savoury finish that perfectly complements the natural sweetness of the seafood.

As a diabetes-friendly option, this recipe is naturally low in carbohydrates and high in lean protein. Using heart-healthy olive oil and fresh herbs ensures a depth of flavour without the need for heavy sauces. Serve these jumbo prawns on a large sharing platter with plenty of lemon wedges for a fresh, zesty kick that brings all the Mediterranean flavours to life.

Ingredients for Head-On Prawns with Chilli, Garlic, and Parsley

  • 6 tablespoons olive oil, divided, plus more for grill

  • 2 garlic cloves, finely chopped

  • 2 tablespoons finely chopped fresh parsley

  • 1/2 teaspoons crushed red pepper flakes

  • 12 head-on, tail-on prawns or jumbo prawns (1 1/2–900g )

  • Kosher salt, freshly ground pepper

  • Flaky sea salt

  • Lemon wedges (for serving)

How to make Head-On Prawns with Chilli, Garlic, and Parsley

Prepare grill for medium-high heat; oil grate. Combine garlic, parsley, red pepper flakes, and 60ml oil in a medium bowl.

Working one at a time, use kitchen shears to cut along the length of the back of each prawn just deep enough into flesh to expose vein; remove. Toss prawns with remaining 2 tablespoons oil in another medium bowl; season with kosher salt and pepper.

Grill prawns, turning occasionally, until shells are bright red and meat is cooked through (it will look slightly opaque), about 5 minutes. Transfer to bowl with garlic-parsley mixture and toss to coat; season with kosher salt and pepper. Transfer prawns to a serving platter and pour garlic-parsley mixture over; sprinkle with sea salt. Serve with lemon wedges for squeezing over.
