Easy Slow Cooker Cod Dieppoise with Creamy Shrimp and Mushroom Sauce Step-by-step instructions

Before you start

Before beginning, ensure all ingredients are ready. Peel and devein the shrimp, and slice the mushrooms into even pieces. Have the slow cooker set on a flat, heat-resistant surface near an electrical outlet.

Because this recipe uses raw seafood, maintain a clean workspace and wash hands thoroughly after handling the raw fish and shrimp to prevent cross-contamination. Keep all ingredients refrigerated until the moment they are needed to ensure maximum freshness throughout the cooking process.

Instructions

Preparation and Layering

1. 1Layer the fish and vegetables
   Place the fresh cod fillets at the bottom of the slow cooker insert. Evenly scatter the sliced mushrooms over the top of the fish, followed by the shrimp. Ensure the ingredients are distributed in a relatively even layer to promote uniform cooking throughout the process.
   Look for The fish should form a single base layer at the bottom of the slow cooker.
   Tip Pat the cod fillets dry with a paper towel before placing them in the cooker to remove excess surface moisture.

At this stage, the cod should be neatly arranged at the bottom of the slow cooker with the mushrooms and shrimp distributed evenly on top. The ingredients should look fresh and ready for the liquid. Ensure the slow cooker is clean and the power cord is positioned safely before adding the liquids.

Adding Aromatics and Liquid

2. 2Add aromatics and liquids
   Crumble the fish bouillon cube directly over the shrimp and mushrooms. Pour the dry white wine and the heavy cream over the entire mixture. Do not stir the ingredients; the liquids will naturally settle around the fish as the slow cooker heats up.
   Look for The liquid should partially cover the fish and shrimp.
   Tip Use a dry white wine such as Sauvignon Blanc or Pinot Grigio for the best flavor balance.

The wine and cream mixture should be poured carefully over the ingredients. The bouillon should be distributed evenly to ensure the seasoning is consistent.

Do not mix; the liquid will find its way to the bottom, surrounding the fish and shrimp to create the poaching environment needed for tender results.

Slow Cooking

3. 3Slow cook and serve
   Cover the slow cooker and cook on the low setting for approximately 3 hours. The cod is done when it is opaque and flakes easily with a fork, reaching an internal temperature of at least 145°F (63°C). Serve immediately while hot, ensuring the creamy sauce is spooned over the fish.
   Look for The fish is flaky and opaque, and the sauce has thickened slightly.
   Safe temperature 145°F (63°C) internal temperature (fish)
   Tip Check the internal temperature of the thickest part of the fish to ensure it reaches the safe threshold.

During the final phase, the slow cooker will be steaming and the kitchen will fill with a delicate, savory aroma. The fish and shrimp will be fully cooked, and the sauce will appear glossy and slightly thickened. The dish is ready to be served immediately once the fish flakes easily.

Common mistakes

A common mistake is overcrowding the slow cooker, which can prevent the fish from cooking evenly. Ensure the cod fillets are in a single layer at the bottom.

Another error is stirring the dish during the cooking process; keep the lid on as much as possible to maintain a stable internal temperature. Finally, ensure the bouillon is fully crumbled, as large chunks may not dissolve properly in the limited amount of liquid provided in the recipe.

How to tell it’s done

The cod is done when it reaches an internal temperature of 145°F (63°C). Visually, the flesh should be opaque and separate easily into firm flakes when gently nudged with a fork.

The shrimp should be pink and opaque throughout, with no signs of translucency. Avoid overcooking, as the cod will lose its delicate texture if left in the heat for too long after it has reached the target temperature.

• Fish: 145°F (63°C) in the thickest part
• Shellfish: 145°F (63°C) in the thickest part
