Salmon can easily turn dry, stringy, or burned if not prepared correctly, but a simple mayonnaise coating ensures every fillet stays juicy and full of flavour. Journalist Katherine McPhillips, who shares the recipe, swears by this unusual method after struggling with overcooked salmon.
The Problem with Cooking Salmon
Many people simply place a salmon fillet in the oven or air fryer, but salmon is exceptionally lean and lacks sufficient fat to shield the skin from heat. This causes the fat to render quickly and the proteins to expel moisture, resulting in lost juices and a dry texture.
Mayonnaise as the Secret Ingredient
Mayonnaise, made of oils, eggs, and a touch of acid, forms a protective barrier around the fish, maintaining the skin's moisture and reducing moisture loss. It ensures the salmon remains succulent throughout cooking and crisps the skin towards the end, leaving a golden-brown, buttery texture. The coating mostly cooks off, so the salmon won't taste like mayonnaise.
McPhillips admitted: "When I first read about cooking salmon with mayonnaise, I thought it was bizarre and even disgusting, but I was fed up with it coming out of the oven overcooked. I decided to try it out at least once, and I can confirm that mayonnaise is the key to making salmon flavourful with the perfect golden and slightly crisp texture."
How to Make Tastier Salmon Fillets
You will need (per person): one salmon fillet, two teaspoons of mayonnaise, one teaspoon of lemon juice, half a teaspoon of smoked paprika, half a teaspoon of Dijon mustard, half a teaspoon of honey, a slight drizzle of olive oil (optional), and salt and pepper.
Preheat the oven to 180°C and line a baking tray with greaseproof paper. Mix the mayonnaise and lemon juice in a small bowl until smooth. Place the salmon skin-side down on the tray. Add a drizzle of olive oil if using a particularly large fillet, though it's generally unnecessary with mayonnaise.
In a separate bowl, combine the smoked paprika, Dijon mustard, and honey, then apply generously to the salmon. Spread the lemon-infused mayonnaise evenly over the fillet. Bake for approximately 20 minutes, checking after the 15-minute mark.
The finished salmon emerges rich, buttery, and perfectly succulent, with every mouthful melting on the tongue—without demanding excessive time in the kitchen.
