Xanthan Gum Free Herb-Baked Mackerel with Lemon and Olive Oil
Flaky, golden-edged mackerel fillets baked with lemon rounds, sliced garlic, and a warm spice rub of turmeric and smoked paprika — this dish is the kind of weeknight dinner that looks far more impressive than the effort it takes. The bright finish of fresh parsley, dill, and thyme scattered straight from the oven keeps everything tasting alive and aromatic. Because the whole recipe is built around whole fish, olive oil, fresh herbs, and spices, there are no hidden thickeners or stabilizers to worry about — every ingredient is exactly what it says it is. That matters more than people realize, since xanthan gum quietly shows up in spice blends, marinades, and bottled dressings that seem perfectly innocent. Here, you control every component from start to finish. Mackerel is also one of the most richly flavored oily fish you can cook, and the high-heat bake crisps the skin beautifully while keeping the flesh moist and tender inside. Squeeze a little extra lemon over the top before serving and you've got a clean, vibrant plate that needs absolutely nothing else.
