Sheet Pan Mackerel with Sweet Potato

Place the chili, shallots, garlic, ginger, paprika, lime zest and juice, and 1 tablespoon of water into a small food processor and blend until smooth.

Preheat the oven to 200°C. Place the sweet potato in a large baking tray and toss with the oil. Add the curry paste and paprika, then bake for 35-40 minutes until the potato is tender. Heat the grill to high.

Score the skin of the mackerel in a few places with a sharp knife. Place the fish on top of the vegetables, skin-side up, then grill for 4-5 minutes until the skin blisters and the flesh is cooked through.
