On Fish the Dish, host Spencer Watts often highlights traditional European sauces and accompaniments that elevate simple dishes into memorable meals. This rouille recipe perfectly captures that philosophy through bold flavour, rustic texture, and classic French inspiration.

The Inspiration

Unlike classic mayonnaise-based sauces, this version incorporates cooked Yukon gold potato, creating a thicker, richer texture that spreads beautifully over warm garlic toast. The anchovies provide savoury depth without overpowering the sauce, while garlic, Dijon mustard, and lemon juice balance the richness with brightness and acidity.

On Fish the Dish, Spencer Watts frequently explores rustic coastal cooking traditions that focus on layered flavour and comforting textures. This recipe reflects that approach by combining simple pantry ingredients into something deeply flavourful and versatile.

The garlic toast adds crisp texture and buttery richness that perfectly complements seafood soups and stews. Together, the rouille and toast become more than a side dish—they become an essential part of the overall dining experience.
