Mackerel stuffed with Dijon mustard, grilled on the barbecue. This is a French way to prepare whole Mackerel. Simple, quick, cheap and full of health benefits.
Garnish the inside of the mackerel very generously with 2 large tablespoons of Dijon mustard in each.
Leave to cool for two hours.
Barbecue cooking
Light your barbecue and place the mackerels on the BBQ grill (ideally a double grill).
Cook for 5 to 10 minutes on each side. Serve immediately.
Oven cooking
Preheat your oven to 180°C/350°F.
Option 1 in the oven cooked in foil: Wrap the mackerels separately, each in a foil parchment paper or aluminum foil.
Option 2 in a baking dish: Add a bowl of water to create some humidity in the oven. Place the mackerel garnished with mustard in the frying pan or in a baking dish. Add a little liquid of your choice, drizzle of olive oil and/or lemon juice and/or white wine.
Cook for around 15 minutes depending on the size of your mackerel, flipping them over halfway through cooking.
Notes
For this recipe, I give you 3 options. 1 grilled on the barbecue, and 2 in the oven, either in foil or in a dish, adding a little liquid to prevent your mackerel from drying out.I recommend starting 2 hours in advance to give the mustard time to diffuse its flavors into the mackerel flesh. This is, of course, optional but will allow you to have deliciously flavored flesh.
