A super easy recipe featuring omega-3 rich and inexpensive mackerel. Its oily meat and strong taste is highly prized by discerning gourmets, but it might not initially appeal to first time eaters.

2 mackerel fillets 200 g
1/2 tsp olive oil 2.5 mL
1 pinch salt [optional] 0.2 g
ground pepper to taste
1/2 onions, sliced crosswise 100 g

Before you start

Keep the serving plates warm on the stove while you're preparing the dish.


  1. Preheat the oven to 175ºC/350ºF.
  2. Slice the onion crosswise, then separate the segments to make rings.
  3. Arrange the fillets (can be either fresh or frozen) on a cooking dish or plate. Brush lightly with oil, then season with salt and pepper to taste. Cover each fillet with the onion rings.
  4. Place in the middle of the oven and cook for about 20 min (25 min if frozen) until the flesh turns white. It is important to check with a fork to see if they are cooked through, since they get tough and dry when overcooked.
  5. Serve on the warmed plates.
