Easy Slow Cooker Cod Bourride with Creamy Aioli Step-by-step instructions

Before you start

Before beginning, ensure your slow cooker is clean and placed on a stable, heat-resistant surface. Wash and slice the leeks and celery into uniform pieces to ensure consistent cooking.

Prepare the cod by patting it dry and checking for any remaining bones. If using a homemade aioli, ensure it is prepared and ready to use before you start the assembly process.

Instructions

Assembly of ingredients

1. 1Prepare the base
   Place the fresh cod fillets into the bottom of the slow cooker in an even layer. Ensure the fish is cleaned and prepared properly before adding it to the cooker.
   Look for The fish should cover the base of the slow cooker.
   Tip Pat the fish dry with paper towels before placing it in the cooker to remove excess moisture.

At the end of this phase, the slow cooker should contain a layer of fresh cod covered by a bed of sliced leeks and celery, with dollops of creamy aioli distributed across the top. Everything should be neatly arranged and ready for the heating process. Ensure the lid is securely in place to trap the moisture needed for gentle, even cooking.

Cooking process

2. 2Add vegetables and sauce
   Scatter the sliced leeks over the cod fillets. Follow this by scattering the sliced celery over the leeks. Finally, drop spoonfuls of the creamy aioli across the top of the vegetables.
   Look for The vegetables should be distributed evenly over the fish.
   Tip Slice your vegetables to a uniform thickness so they cook evenly throughout the process.

During the cooking phase, the slow cooker will gently heat the fish and vegetables, allowing the leeks and celery to release their aromatic juices. The aioli will slowly melt into the base, creating a glossy, flavorful sauce that coats the fish. The kitchen should begin to smell savory and light, indicating that the flavors are successfully melding together.

Final check and serving

3. 3Cook and serve
   Cover the slow cooker and cook on low for 2 hours. The fish is done when it reaches an internal temperature of 145°F (63°C) and the aioli reaches 160°F (71°C). Serve immediately while warm.
   Look for The fish should be opaque and tender.
   Safe temperature 160°F (71°C) internal temperature (egg dishes)
   Tip Avoid overcooking the fish, as it can become dry if left in the slow cooker too long.

Once the cooking time is complete, the fish should be perfectly tender and fully opaque. The vegetables should be soft and well-integrated into the sauce.

Check the internal temperature of the fish to ensure it has reached 145°F (63°C) and the aioli 160°F (71°C). The dish is now ready to be transferred to bowls and served immediately while it is steaming hot and at its best.

Common mistakes

A common mistake is overcooking the fish, which can lead to a dry, rubbery texture. Because white fish is delicate, it requires less time than other proteins.

Avoid cutting the vegetables into pieces that are too large, as they may not soften sufficiently within the cooking time. Additionally, ensure the aioli is placed on top rather than mixed in, allowing it to melt naturally over the ingredients.

How to tell it’s done

The cod is finished cooking when it reaches an internal temperature of 145°F (63°C), and the aioli base reaches 160°F (71°C). You can check this by inserting a meat thermometer into the thickest part of the fillet.

Visually, the fish should be opaque throughout and flake easily when gently prodded with a fork. If the fish still appears translucent or resists flaking, continue cooking for a few additional minutes and recheck the temperature.

• Fish: 145°F (63°C) in the thickest part
• Egg dishes: 160°F (71°C) in the thickest part
