Ingredients
- 2 mackerel fillets (approx. 8 oz / 225 g)
- 1.0 tbsp. (0.5 oz / 15 g) olive oil
- 2 large eggs (approx. 3.5 oz / 100 g)
- 1.5 cups (12.0 oz / 340 g) water
- 1 medium tomato, seeded and diced (approx. 4.3 oz / 122 g)
- 2.0 tbsp. (1.0 oz / 28 g) mayonnaise
- 0.5 head green lettuce (approx. 5.3 oz / 150 g)
- Salt and black pepper to taste
Step-by-Step Directions
- Preheat a grill pan over medium heat. Brush the 2 mackerel fillets (8 oz / 225 g) with 1.0 tbsp. (0.5 oz / 15 g) olive oil, and sprinkle lightly with salt and black pepper. Place the fish onto the preheated pan and cook on both sides for 6 to 8 minutes until fully cooked and slightly charred, then set aside.
- Bring 1.5 cups (12.0 oz / 340 g) of salted water to a rolling boil in a small pot over medium heat. Gently drop in the 2 large eggs (3.5 oz / 100 g) and boil for exactly 10 minutes. Once done, run the eggs under cold water to cool, peel off the shells, chop them into small pieces, and transfer them to a salad bowl.
- Gently flake the cooled mackerel fillets into the salad bowl with the chopped eggs. Add the diced 1 medium tomato (4.3 oz / 122 g) and 2.0 tbsp. (1.0 oz / 28 g) mayonnaise to the bowl. Mix everything evenly with a spoon until the ingredients are well combined.
- Separate the 0.5 head green lettuce (5.3 oz / 150 g) into individual, sturdy leaves. Layer two leaves together to form a firm base for each cup, and fill them by spooning approximately 2.0 tbsp. (1.0 oz / 28 g) of the mackerel and egg salad mixture into each lettuce cup before serving.

Chef's Pro Tips for the Best Results
- Check for Pin Bones: Even if you buy pre-cut mackerel fillets, always run your fingers down the centerline of the fish before grilling. Remove any remaining pin bones with tweezers for a much more pleasant eating experience.
- Crisp Up Your Lettuce: To ensure your lettuce cups have the perfect crunch and can hold the weight of the salad, wash the leaves in ice-cold water and spin them completely dry before assembling. Soggy lettuce will cause the cups to fall apart!
- Lighten the Dressing: If you want to cut down on the fat content while maintaining that creamy texture, try swapping half (or all) of the mayonnaise with plain Greek yogurt. It adds a wonderful tang that pairs beautifully with the rich mackerel.
- Add a Citrus Kick: Mackerel is a beautifully rich and oily fish that benefits greatly from a touch of acidity. A quick squeeze of fresh lemon juice over the fish right after grilling will brighten up the entire flavor profile of your dish.
Frequently Asked Questions (FAQ)
Can I make these Mackerel Lettuce Cups ahead of time? Yes, you can easily meal-prep the components! However, to prevent the lettuce from becoming soggy, it is highly recommended to store the mackerel and egg salad mixture in an airtight container in the fridge separately from the washed lettuce leaves. Simply assemble your Mackerel Lettuce Cups right before you are ready to eat.
What is the best lettuce for making Mackerel Lettuce Cups? While this recipe calls for standard green lettuce, Butterhead (Boston or Bibb) and Romaine hearts are fantastic alternatives. Butterhead lettuce offers a natural, bowl-like shape that holds the filling perfectly, while Romaine provides a much sturdier, satisfying crunch.
Can I use canned fish for this Mackerel Lettuce Cups recipe? Absolutely! If you are short on time, you can substitute the freshly grilled fillets with high-quality canned mackerel (drained well). It transforms this into a completely no-cook recipe (aside from boiling the eggs) while still delivering an excellent, high-protein meal.
