I absolutely love mackerel. It’s one of my favourite fish. High in omega 3 healthy fats which help keep inflammation at bay. Mackerel is also rich in monounsaturated fat which can help lower your chances of heart disease and diabetes.

My favourite way to enjoy it is grilled or oven roasted until crisp. Today marinated in a sugar free keto friendly ginger dressing with crushed broccoli, sun-dried tomatoes, peppers and crunchy toasted almonds. Ready in less than 30 minutes and super cheap to make.

This low-carb mackerel lunch bowl is ideal for those who practice intermittent fasting and only eat two nutritious meals a day. Try to eat fatty fish 2-3 times a week to get the maximum health benefits and buy from a sustainable source.

  2. Place the mackerel fillets on the baking tray skin side up and roast for 10 - 12 minutes until crispy, or to your liking. (If you're short on time, skip the marinating and simply bake in the oven.)
  3. Place the almonds on a separate baking tray and roast in the oven for 6 minutes until golden. Remove from the oven and allow to cool before chopping them.
