Ingredients

Why this recipe works

The slow cooker environment provides a gentle, consistent heat that is ideal for delicate protein like white fish. Unlike high-heat cooking methods that can easily toughen or dry out fillets, the slow cooking process ensures the fish remains moist and tender while allowing the aromatics like leeks and celery to soften perfectly.

Layering the ingredients is key to the success of this dish. Placing the fish at the bottom allows it to absorb the moisture released by the leeks and celery, while the aioli on top slowly melts and creates a rich, emulsified sauce as the dish cooks.

This creates a balanced, cohesive flavor profile without needing to stir or disturb the delicate contents.

Notes and substitutions

When selecting cod for this recipe, look for thick, firm fillets that appear translucent and have a fresh, mild scent. If cod is unavailable, other firm white fish varieties such as haddock, halibut, or pollock work exceptionally well. Ensure all bones are removed before cooking to provide the best eating experience for everyone at the table.

The aioli used in this recipe can be a high-quality store-bought version or a homemade batch prepared in advance. Using a robust, garlic-forward aioli will significantly enhance the final dish.

If you choose to make your own, ensure it is properly chilled before adding it to the slow cooker to maintain the integrity of the sauce as it begins to warm through.
