Peanut Free Herb-Baked Mackerel with Lemon and Olive Oil
Mackerel is one of those underrated weeknight heroes — rich, meaty, and deeply flavorful in a way that holds up beautifully to bold seasoning. Here, skin-on fillets get rubbed with a warm blend of turmeric, smoked paprika, and black pepper before hitting a hot oven, so the spices bloom and the flesh stays incredibly moist. Thin lemon rounds and sliced garlic roast right alongside the fish, softening into something almost jammy and fragrant by the time everything comes out of the oven. A generous scatter of fresh parsley, dill, and thyme goes on at the very end, keeping the herbs bright and aromatic rather than wilted. The whole thing comes together on a single parchment-lined baking sheet, which means cleanup is as easy as the cooking itself. Because every ingredient here is straightforward and naturally sourced, there's no need to scan labels or worry about hidden additives — just clean, confident cooking from start to finish. Serve it with extra lemon wedges and something crusty to soak up all that herby olive oil pooled on the pan.
