Before you start

Before beginning, ensure all ingredients are measured and ready for assembly. Thoroughly rinse the fennel and peel the onion, then slice both vegetables into thin, uniform strips to promote even cooking. Ensure the fish is patted dry and free of any loose scales or bones.

The slow cooker should be clean and placed on a flat, stable surface with the power cord positioned safely away from water sources and heat-sensitive items. Having everything prepared allows for a seamless transition into the assembly phase.

Ingredients at a glance (6)
  • 1 1/2 lb pollack fillets
  • 2 cups fennel, thinly sliced
  • 1 cup yellow onion, thinly sliced
  • 1 tsp fennel seeds
  • 3/4 cup heavy cream
  • 2 tbsp pastis

Instructions

Assembly of the base

  1. Prepare the slow cooker bed
    Place the pollack fillets in the bottom of the slow cooker, ensuring they are arranged in a single layer. Scatter the thinly sliced fennel and yellow onion evenly over the fish to create a flavorful aromatic base that will infuse the fish as it cooks.
    Look for Fish fillets are arranged in an even layer at the bottom of the cooker.
    Tip Ensure the fennel and onion are sliced uniformly so they cook at the same rate.

The fish is arranged in a single, even layer at the bottom of the slow cooker, topped with a uniform bed of sliced fennel and onions. The prep area is clean, and the aromatics are ready for the final seasoning and liquid addition.

Adding liquids and seasoning

  1. Season and add liquids
    Sprinkle the fennel seeds over the top of the fish and vegetables. In a small glass measuring cup, combine the heavy cream and pastis, stirring gently to incorporate. Pour this mixture carefully over the contents of the slow cooker to ensure the fish is lightly coated.
    Look for The cream mixture completely covers the fish and aromatics.
    Tip Using a measuring cup helps distribute the liquid evenly across all sides of the ingredients.

The fennel seeds are evenly distributed, and the cream and pastis mixture has been poured over the fish. The ingredients look well-proportioned, and the slow cooker is ready to be covered and started on the low setting.

Final cooking and serving

  1. Cook until tender
    Cover and cook on low for approximately two hours until the fish is opaque and flakes easily with a fork, reaching an internal temperature of 145°F (63°C). Serve immediately, ensuring any leftovers are cooled within two hours before refrigeration.
    Look for Fish should be opaque and tender throughout.
    Safe temperature 145°F (63°C) internal temperature (fish)
    Tip Check for doneness early, as fish can overcook quickly even in a slow cooker.

The fish is opaque, tender, and releases easily with a fork, with the cream sauce appearing glossy and aromatic. The internal temperature reaches 145°F (63°C), indicating the dish is safe and ready to be served immediately.

Common mistakes

A common mistake is overcrowding the slow cooker, which can prevent the fish from cooking evenly and lead to uneven texture.

Ensure the fillets are arranged in a single layer to allow the heat to circulate properly. Another error is using too much liquid, which can dilute the delicate flavors of the cream and pastis.

Stick to the provided measurements to maintain the proper consistency. Finally, avoid lifting the lid frequently during the cooking process, as this releases heat and significantly increases the total cooking time required.

How to tell it’s done

The pollack is properly cooked when it is entirely opaque and flakes easily when gently tested with a fork. It is crucial to monitor the internal temperature, ensuring it reaches at least 145°F (63°C) throughout the thickest part of the fillet.

The sauce should be glossy and slightly thickened from the cream, coating the back of a spoon. Avoid overcooking, as even a few minutes too long can cause the fish to lose its structure and become mushy in the creamy liquid.

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