Baked Mackerel

Clean the fish, rinse under cold water, and pat dry with paper towels. Make small diagonal slits along the sides of each fish to let the marinade soak in evenly.

Season with salt, pepper, and the juice of half a lemon squeezed directly over the fish. Rub the mixture in thoroughly by hand on all sides, paying special attention to the slits. Drizzle each fish with a little vegetable oil and let marinate at room temperature for 15 to 30 minutes.

Preheat the oven to 350°F (180°C). Place the fish on a baking sheet lined with parchment paper or foil.

Bake for about 20 to 25 minutes. Check for doneness with a knife—the flesh should be tender and easily flake apart.
