Mackerel is a delicious fatty fish that hardly needs any seasoning. It's one of the best sources of protein, healthy fats, (omega 3 fatty acids) and micronutrients (magnesium, potassium, phosphorus, iron, vitamin A and D).
It's also one of your best fish choices because it's sustainable. However, beware that some types of mackerel may be high in mercury - go for North Atlantic mackerel and avoid Spanish and King mackerel are high in mercury.
You can use lamb lettuce, rocket, romaine, iceberg lettuce or even red leaf lettuce. From a nutritional perspective, the darker the lettuce leaf, the more nutrition it has (potassium, calcium, vitamin A, C and other micronutrients).
Step-by-step
Start by cooking the eggs. Fill a small saucepan with water up to three quarters. Add a good pinch of salt. This will prevent the eggs from cracking.
Bring to a boil. Using a spoon or hand, dip each egg in and out of the boiling water - be careful not to get burnt. This will prevent the egg from cracking as the temperature change won't be so dramatic. To get the eggs hard-boiled, you need round 10 minutes. This timing works for large eggs. When done, remove from the heat and place in a bowl filled with cold water. I always use my egg timer.

Cook the green beans. Fill a small sauce pan with water and season with salt. Add the green beans and bring to a boil. Cook until crisp tender for 4-5 minutes. When done, take off the heat and pour the hot water away to prevent the beans from further cooking.

Make small diagonal slashes on the skin side of the mackerel - don't cut too deep. Season with salt and pepper from both sides.

Heat a pan greased with ghee. Once the pan is hot, add the mackerel fillets, skin side down, and cook over a medium-high heat until the skin is crispy and the meat opaque and cooked. When done, take off the heat and set aside. You can use splatter shield as it's great for catching spat oil.

When the eggs are chilled, peel off the shells. Make the dressing by mixing all the ingredients (olive oil, mustard and lemon juice).

Place washed and drained lettuce in a serving bowl and top with the cooked green beans.

Add quartered cooked eggs, sliced mackerel fillet and drizzle with the prepared dressing. Best served immediately but can be stored in the fridge for up to a day.

Hi. I am an epileptic and have stumble upon the ketogenic diet through research. I would like to get started, is there any ketogenic meal replacements I can use because money is tight.
Hi Heather, you will need to follow a restricted ketogenic diet. For more information, check out these posts:

Hi Martina,
Are these mackerel that come from a can?
Hi Anna, I used fresh mackerel which I baked but canned mackerel will work too 😊
Hi Martina!
I'm new to KetoDiet and I found your blog which seems excellent! Thank you!
Quick question: When you mention (180 g / 6.3 oz) for the mackerel, is it for each portion or for the two portions? Same for the avocado and the green beans?
Thank you!
Thank you Jocelyne! All ingredients listed are per recipe (that is 2 servings in this case), so the amount of mackerel, avocado, etc are per 2 servings.
Thanks for sharing.
Fixed this salad tonight and received rave reviews from my toughest critic, my wife! I had to substitute salmon for the mackerel, sometimes you do what you have to do. It was great and will move to one of my regular go to meals.
Yes I know what you mean and I think that salmon is a great substitute because nutritionally it's very similar to mackerel. Glad you liked it! 😊
Hi Martina, I love love love your blog! I appreciate that you post healthy foods like mackerel and not just low-carb versions of everything high in carbs. Thanks for keeping it real!! 😊
Thank you Amy! ❤️
