Transform humble white fish into a restaurant-quality meal with the magic of a slow cooker. This method gently poaches the pollack in a fragrant, creamy sauce that highlights the delicate anise notes of fennel and pastis, creating an elegant dish with minimal hands-on time for busy evenings.
Slow cooking is often reserved for tough cuts of meat, but it is an exceptional technique for delicate fish. By braising pollack in a bath of heavy cream and aromatic pastis, the fish remains incredibly moist and absorbs the complex flavors of the fennel and onion.
This recipe is designed for ease and elegance, providing a sophisticated dinner that requires only a few minutes of preparation before the slow cooker handles the rest, allowing the flavors to meld perfectly into a luscious, silky sauce.
Ingredients
- 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
Why this recipe works
The low-temperature cooking environment of a slow cooker allows the pollack to poach gently in the cream and pastis mixture. This prevents the fish from becoming dry or tough, which often happens with high-heat methods like searing or rapid boiling. The steady, ambient heat ensures the fillets remain tender and succulent while allowing the fennel and onion to soften into a sweet, flavorful garnish that complements the mild profile of the fish perfectly.
The combination of fennel and pastis creates a unique, layered flavor profile that is deeply rooted in Mediterranean cooking traditions. As the fennel seeds and sliced bulbs slowly release their essential oils, they infuse the heavy cream with a subtle, earthy sweetness.
The pastis adds a distinct, sophisticated aroma that cuts through the richness of the dairy, resulting in a balanced sauce that highlights the natural quality of the pollack without overpowering its delicate texture.
Notes and substitutions
Pollack is an excellent choice for this recipe due to its mild flavor and firm, flaky texture. If pollack is unavailable at the local fish counter, cod or haddock are reliable alternatives that behave similarly during the cooking process.
Ensure the fillets are fresh and free of any strong odors before adding them to the slow cooker to guarantee the best results for your final dish. Always handle raw fish according to standard food safety guidelines, keeping it cold until the moment of preparation.
The choice of equipment is straightforward, as any standard oval or round slow cooker will work well for this preparation. When selecting fennel, look for bulbs that are firm, white, and free of brown spots, with bright green fronds if possible.
The fennel seeds contribute a concentrated burst of flavor, so it is important to use them as specified. If the sauce appears too thin after cooking, it can be gently reduced in a small saucepan over medium heat for a few minutes before serving.
- Pastis: Use anisette, sambuca, or a teaspoon of anise extract diluted with a tablespoon of dry white wine for a similar flavor profile.
- Pollack: Substitute with other firm white fish such as cod, haddock, or halibut which will hold their shape well during the slow cooking process.
