Oven-baked mackerel with herbs and lemon is a nutritious mediterranean family dinner. This high protein dish is rich in omega-3s, fresh, and supports a healthy lower cholesterol or dash diet plan.
Preheat the oven to 400°F, ensuring the rack is positioned in the center for even heat circulation.
Rinse the mackerel fillets and pat them dry with paper towels. Arrange them in a single layer on a lightly oiled baking dish.
Sprinkle salt and black pepper evenly on both sides of each fillet. Drizzle extra-virgin olive oil over the fish.
Finely chop the parsley and garlic. Slice lemons into rounds. Layer the garlic, parsley, and lemon slices over the mackerel fillets.
Bake uncovered for 18–22 minutes, until the fish is just cooked through, flakes easily with a fork, and the lemon slices have softened. Serve immediately.
