We all love a good BBQ, especially during the warmer months. While a plethora of red meats, sausages and burgers are a popular choice, the healthier, and often tastier, alternative is to cook fish on the BBQ. One particular fish that is delicious on the old grill is mackerel. Mackerel on BBQ? Perfect! This tasty fish is full of essential vitamins and minerals and grills well.
The best thing about BBQing mackerel is that you can do so on a huge set-up just as easily as you can on a quality fire pit BBQ. Before you throw your mackerel on BBQ, here are some tips on retaining the best this fish offers in terms of taste and nutrition.
As with many proteins, mackerel can be overcooked as well as undercooked. If you undercook mackerel, you risk food poisoning or parasite infestation. Overcooking is also not good as the flesh is then dry and tough to eat. So, the big question is, what temperature should mackerel be cooked?[i]
When we consider the right temperature for cooking mackerel, it depends on the cooking method. When it comes to cooking mackerel on BBQ, you should aim for an internal temperature of around 63°C. While you can just guess and cook the mackerel on both sides until golden brown, grilling is tricky because you may not be able to gauge the exact cooking temperature. Play it safe and invest in a meat thermometer and check by inserting the probe in the thickest part of the fish.
Preparing mackerel for BBQing is easy, especially if you have a good fishmonger. Many fresh fish markets will de-scale and gut the fish for you; this is half the job done. However, if you’re bringing home the whole mackerel, you will have to do most of the prep work yourself. To prepare mackerel for BBQing, follow these simple steps.

One of the best things about mackerel on BBQ is that it doesn’t have an overwhelming “fishy” taste, especially if you can get your hands on fresh mackerel. The flesh is more on the sweet side and isn’t too salty. This means you can add lots of flavours using herbs and spices when BBQing. Here’s one recipe that will become a family favourite.
You will need the following:
When serving mackerel cooked on the BBQ, a nice mixed salad is always a great choice. However, when you are entertaining, you usually want to offer more side dishes to ensure there is plenty of food to go around and to impress your guests with your culinary expertise.
Here are some tasty side dishes that go well with BBQed mackerel:
Creamy potato salad – The ultimate comfort food, a nice creamy potato salad is rich and, yes, creamy, which makes it a great accompaniment to the lightness of mackerel.
Spicy tomato pasta – Supercharge your mackerel dinner with a nice serving of spicy tomato pasta. The fish is generally nice and light, so you can get away with adding some tasty carbs.
Freshly baked bread – Bread is always a great addition to the table, and if you have the baking skills, you can really impress your guests with a loaf of homemade bread. Otherwise, find a good bakery and get a nice crunchy baguette or a loaf of sourdough bread.
Grilled vegetables – While you’ve got the grill fired up, why not add some tasty grilled vegetables to your BBQed mackerel? You can literally choose any of your favourites for grilling.
Potato Wedges or chips – Just because you’ve BBQed your mackerel doesn’t mean you can’t have an old favourite on the table. Fish and chips are always winners, so go for ordinary chips or wedges. Fried or baked in the oven, you can’t go wrong.
Beetroot salad – The complex earthiness of beetroots goes really well with the subtle flavours of mackerel. There are many different beetroot salad recipes you can choose from.
Cucumber and yoghurt salad – This is an easy salad to prepare, and all you need is a few fresh cucumbers, a tub of yoghurt, some lemon juice, and salt and pepper. If you’re feeling adventurous, you can also add some Dijon mustard to the dressing.
Fried Rice – This is one of the easiest side dishes to make, and it doesn’t need to be complicated. Prepare some rice, as per the instructions on the packaging. Then, chop up your favourite vegetables or buy a bag of your favourite frozen mixed vegetables. Add some oil and spices in a large frying pan or wok before adding your vegetables. Once the veggies are coated with oil and spices, stir in your rice.
Mustard Sauce – There are many variations of mustard sauce that go well with mackerel, and this simple one really works well. Simply mix your favourite mustard with olive oil, lime juice and a little vinegar, and you have the perfect sauce for your mackerel.
Sweet Chilli Sauce – You can make your own sweet chilli sauce, or you can buy a ready-made one.
There are no rules when it comes to serving side dishes with your BBQed mackerel, and you are only limited to your imagination and what ingredients you have available.
One of the best things about owning a fire pit is that they are perfect for those who have limited space in their gardens. Apart from being perfect for cooking mackerel on BBQ, once you start using your fire pit, you’ll find yourself experimenting with different meats, seafood, vegetables and even desserts. Of course, there will be times when you will also want to use your fire pit for outdoor warmth or just create a quiet, romantic oasis after a long week of working.
We all love food that has been grilled on the BBQ, and mackerel will fast become a family favourite. This fish is one of the healthiest, and you can also grill other fish or different proteins.
