BHA & BHT Free Herb-Baked Mackerel with Lemon and Olive Oil
Mackerel is one of those deeply flavorful, omega-rich fish that deserves far more attention than it gets, and baking it with a bold spice rub is the best way to let it shine. The combination of turmeric, smoked paprika, and black pepper creates a warm, aromatic crust, while thin lemon rounds and sliced garlic perfume the whole pan as it roasts. A generous finish of fresh parsley, dill, and thyme added right out of the oven keeps the herbs bright and fragrant rather than wilted and dull. For anyone navigating preservative sensitivities, packaged fish seasonings and bottled sauces are common culprits for hidden additives — this recipe sidesteps all of that by relying entirely on whole spices, fresh herbs, and extra-virgin olive oil. Every single ingredient is clean and straightforward, so there's no label-reading required. The result is a restaurant-worthy plate that comes together on a single baking sheet with minimal cleanup and maximum flavor.
