Before you start
Before starting, ensure all ingredients are properly prepped. Clean the leeks by slicing them lengthwise and rinsing under cold water to remove any trapped dirt, then slice thinly. Cut the cod into even chunks, ensuring they are free of any pin bones.
Measure out the rice and cream so they are ready for quick assembly. Having everything organized prevents last-minute scrambling and ensures that you can layer the ingredients efficiently for the best cooking results.
Ingredients at a glance (4)
- 1 lb cod fillets, cut into large chunks
- 2 medium leeks, cleaned and thinly sliced
- 1 cup long-grain white rice, uncooked
- 1/2 cup heavy cream
Instructions
Layering the ingredients
- Layering the basePlace the chunks of cod fillets evenly across the bottom of the slow cooker insert. Ensure the fish is distributed in a single layer to promote even cooking throughout the process.Look for The cod should be arranged in a flat, even layer without overlapping significantly.Tip Pat the fish dry with a paper towel before placing it in the slow cooker to prevent excess moisture.
The cod is arranged at the bottom of the slow cooker, creating a stable base for the other ingredients. The fish chunks should be relatively uniform in size to ensure they cook evenly. This phase is complete once the fish is placed and ready for the aromatics.
Adding aromatics and rice
- Adding aromatics and grainsScatter the thinly sliced leeks over the cod pieces. Follow this by sprinkling the uncooked white rice evenly over the top of the leeks to ensure it absorbs the cooking juices.Look for The leeks should cover the fish completely, and the rice should be distributed in a uniform layer.Tip Wash leeks thoroughly in cold water to remove any hidden grit between the layers.
The sliced leeks are scattered over the fish, followed by a layer of uncooked rice. The leeks should be spread out to distribute their flavor evenly. At this stage, the slow cooker insert should be layered with the fish, leeks, and rice, ready for the final component.
Final assembly and cooking
- Final assembly and cookingPour or dollop the heavy cream over the rice and leeks. Cover the slow cooker and cook on the low setting for approximately 4 hours, or until the fish reaches an internal temperature of 145°F (63°C).Look for The fish should flake easily with a fork and the rice should be tender.Safe temperature 145°F (63°C) internal temperature (fish)Tip Avoid lifting the lid during the cooking process to maintain a consistent temperature inside the slow cooker.
The cream is poured over the ingredients, and the slow cooker is covered. The dish is cooking, and the aroma of sweet leeks and creamy fish should begin to fill the kitchen. The phase is complete when the fish is fully cooked and the rice is tender.
Common mistakes
Avoid overcooking the cod, as even in a slow cooker, fish can become dry if left for too long.
Ensure that you do not stir the ingredients during the cooking process; the beauty of this recipe is in the layering, and stirring will break the fish into small, unappealing pieces.
Additionally, do not use instant rice, as it will turn into a mushy consistency long before the fish is cooked. Stick to traditional long-grain white rice for the best structural results.
How to tell it’s done
The dish is finished when the cod is opaque and flakes easily when tested with a fork. It should reach an internal temperature of at least 145°F (63°C) at its thickest point.
The rice should be tender and have absorbed most of the creamy liquid, creating a cohesive, comforting texture. If the rice still has a bit of a bite, you can let it sit for an additional ten minutes on the warm setting to finish absorbing the remaining moisture.
