Steps – How to Cook Codfish à la Lyonnaise

Step 1: Prepare the Ingredients

1. Boil the Codfish (if not already cooked):
• Bring a pot of water to a boil, add a pinch of salt, and gently add the codfish fillet.
• Let it simmer for 8–10 minutes until cooked through.
• Drain, let cool slightly, then flake the fish into small pieces, removing any bones.
2. Boil the Onions and Potatoes:
• Peel and boil the onions in a separate pot for about 10 minutes, or until they become soft.
• Drain and chop or slice them into thin pieces.
• Boil the potatoes with their skins on for about 15 minutes until fork-tender.
• Let them cool slightly, then peel and slice into thin rounds.

Step 2: Cook the Dish

1. Heat the Butter:
• In a large skillet or pan, melt the butter over medium heat until it starts to bubble.
• Stir occasionally to prevent burning.
2. Sauté the Onions:
• Add the boiled and sliced onions to the pan.
• Cook them for 2–3 minutes, stirring occasionally, until they become lightly golden and fragrant.
3. Add the Sliced Potatoes:
• Stir in the sliced potatoes, ensuring they are well-coated with the butter and onions.
• Cook for another 3–4 minutes, allowing the potatoes to absorb the flavors.
4. Incorporate the Codfish:
• Add the flaked boiled codfish to the pan.
• Gently stir the mixture so the fish is evenly distributed without breaking it apart too much.
5. Pour in the Milk:
• Slowly add the milk, stirring everything together to create a smooth and creamy texture.
• Reduce the heat to low, cover the pan, and let the mixture simmer for about 10 minutes to allow all the flavors to meld.
