Before you start
Before you begin, organize your workspace and ensure all ingredients are ready. Peel and slice your potatoes into uniform pieces to ensure they cook through at the same rate.
Pat the fish fillets dry with paper towels to remove excess moisture, which helps the fish maintain a better texture during cooking. Having your measuring cups and the saffron ready will make the assembly process smooth and efficient, allowing you to get the slow cooker started in just a few minutes.
Ingredients at a glance (4)
- 1 1/2 lb white fish fillets, cut into large chunks
- 3 medium potatoes, peeled and sliced
- 1/2 tsp powdered saffron
- 2 cups crushed peeled tomatoes in broth
Instructions
Layering the Fish and Potatoes
- Prepare the BasePlace the white fish fillets into the base of the slow cooker. Scatter the sliced potatoes evenly over the fish to ensure even cooking throughout the process.Look for The fish should form an even layer at the bottom of the cooker.Tip Cut the potatoes into uniform slices so they soften at the same rate as the fish.
At the end of this phase, the fish and potatoes should be neatly arranged in the slow cooker. The fish should be in a single layer at the bottom, with the potato slices covering the surface. Check that the ingredients are not packed too tightly to allow the heat to circulate evenly. The setup should look clean and organized, ready for the addition of the aromatics and the cooking liquid that will transform these raw components into a cohesive stew.
Infusing with Saffron and Tomatoes
- Add Aromatics and LiquidSprinkle the powdered saffron over the fish and potato mixture. Pour the crushed peeled tomatoes in broth over the top, ensuring the ingredients are well-distributed within the slow cooker.Look for The liquid should partially submerge the ingredients.Tip Ensure the saffron is sprinkled evenly to distribute the color and aroma throughout the stew.
Once the saffron and tomato broth are added, the slow cooker should look vibrant and aromatic. The saffron should be distributed across the surface, and the tomato broth should have filled the gaps between the fish and potatoes.
Ensure the lid is closed securely to trap the moisture and heat inside. The smell of the saffron should be noticeable, indicating that the ingredients are ready for the long, slow cooking process that will meld these flavors together.
Gentle Slow Cooking
- Cook and ServeCover the slow cooker and cook on low for 3 hours. Once finished, ensure the fish reaches an internal temperature of 145°F (63°C) to be fully cooked and tender before serving in bowls.Look for The fish should be opaque and flake easily with a fork.Safe temperature 145°F (63°C) internal temperature (fish)Tip Avoid stirring the stew aggressively to keep the fish fillets intact.
At the end of the cooking time, the stew should be bubbling gently and emitting a rich, savory fragrance. The fish should be tender and opaque, having reached the required internal temperature.
The broth should be infused with the golden color of the saffron and the sweetness of the tomatoes. Before serving, give the stew a very gentle lift with a spoon to ensure everything is heated through and the flavors have properly combined for a perfect bowl.
Common mistakes
A common mistake is over-stirring the stew, which can break the delicate fish fillets into small, unappealing pieces. Handle the ingredients gently when adding them to the cooker and avoid unnecessary mixing during the cooking process.
Another error is cutting the potatoes too thickly, which may result in them remaining undercooked while the fish is already done. Ensure your slices are consistent and not excessively thick to achieve the perfect texture for both components of the dish.
How to tell it’s done
The fish is considered done when it reaches an internal temperature of 145°F (63°C). At this stage, the fish will be opaque throughout and should flake easily when tested with a fork. The potatoes should be tender when pierced with a knife. Because slow cookers vary in their heat intensity, it is always a good idea to check the temperature of the thickest part of the fish before serving to ensure it is cooked safely and thoroughly.
