Gut Friendly Herb-Baked Mackerel with Lemon and Olive Oil
Mackerel is one of those deeply underrated fish — rich, meaty, and packed with the kind of omega-3 fatty acids that genuinely support a happy, well-functioning gut. The spice rub here brings together turmeric, smoked paprika, and black pepper, a combination that's as anti-inflammatory as it is delicious. Thin slices of lemon and garlic roast right alongside the fillets, perfuming the whole pan and keeping the fish incredibly moist as it bakes at high heat. Everything comes together in one sheet pan, which means minimal fuss and even less cleanup. Once it comes out of the oven, a generous scatter of fresh parsley, dill, and thyme adds a burst of brightness that makes the whole dish feel restaurant-worthy. The herbs aren't just decorative — they're loaded with plant compounds that complement the gut-supportive goals of the meal without any heavy sauces or hard-to-digest ingredients. Serve it with a squeeze of lemon and you've got a clean, nourishing dinner that's as satisfying to eat as it is easy to pull off.
