Spicy Chicken Thighs with Rhubarb-Cucumber Salsa

These spicy chicken thighs with rhubarb-cucumber salsa offer a sophisticated twist on a high-protein dinner. By slashing the skin and marinating the chicken in a punchy emulsion of Scotch bonnet and garlic, every bite is infused with a deep, savoury heat. The chicken is roasted at a high temperature to ensure the skin becomes perfectly crisp while the meat remains succulent and tender.

To balance the fiery heat of the bird, this dish features a vibrant salsa made from seasonal rhubarb and cooling cucumber. The rhubarb provides a sharp, fruity acidity that cuts through the richness of the chicken, while fresh coriander and lime juice bring a bright finish. It is an excellent choice for those seeking a nutritious, low-carbohydrate meal that does not compromise on complex, gourmet flavours.

Ingredients for Spicy Chicken Thighs with Rhubarb-Cucumber Salsa

  • 1 habanero, Scotch bonnet, or Thai chilli, with seeds, stemmed

  • 2 garlic cloves

  • 2 spring onions, thinly sliced, white and green parts divided

  • 1 tablespoon soy sauce

  • 60ml olive oil

  • 6 large skin-on, bone-in chicken thighs

  • Kosher salt

  • 230g 1/4" cubes rhubarb

  • 150g 1/4" cubes unpeeled seeded English hothouse cucumber

  • 1/2 cup coarsely chopped fresh coriander

  • 1 tablespoon honey

  • 1 tablespoon vegetable oil

  • 1 teaspoon fresh lime juice

  • Freshly ground black pepper

Preheat oven to 260°C. Line a baking sheet with foil. Pulse chilli, garlic, and white parts of spring onions in a food processor until finely chopped. With machine running, drizzle in soy sauce, then olive oil; process until emulsion forms. Transfer sauce to a bowl.

Place chicken thighs, skin side up, on a work surface and slash each crosswise at 3/4" intervals down to the bone. Season lightly with salt. Place on prepared baking sheet and brush with sauce. Bake until skin is crisp and an instant-read thermometer inserted into thickest part of thigh registers 74°C, 20-25 minutes. Grill on high for an additonal 2-3 minutes for crisper skin, if desired. Let rest for 5-10 minutes.

Meanwhile, toss rhubarb, next 5 ingredients, and green parts of spring onions in a medium bowl to coat. Season to taste with salt and pepper and let stand for at least 10 minutes to allow flavours to meld.

Serve chicken with rhubarb salsa alongside.
