Walnut Free Herb-Baked Mackerel with Lemon and Olive Oil
Mackerel doesn't always get the spotlight it deserves, but this herb-baked version is the kind of weeknight dinner that makes you wonder why you ever ignored it. The fillets get rubbed down with a warm blend of turmeric, smoked paprika, and black pepper before hitting a hot oven, so the result is deeply savory with a gorgeous golden color. Lemon rounds and sliced garlic roast right alongside the fish, softening and caramelizing into something almost jammy. A generous finish of fresh parsley, dill, and thyme scattered straight from the oven keeps everything bright and aromatic. The whole thing comes together on a single parchment-lined baking sheet, which means cleanup is as easy as the cooking. For anyone navigating tree nut concerns, this recipe is naturally built around pantry staples and fresh ingredients — no hidden nut oils, no ambiguous spice blends, just clean, confident flavors you can trust.
