Salt Cod with Garlic Olive Oil Cream Sauce

Introduction

Salt cod needs a 24-hour soak before you cook it, but the active work is simple: poach the fish, soften onion in olive oil, and blend it with garlic, lemon juice, and milk or cream until smooth. You get a rich, spreadable sauce that works on toast for a starter or over roasted potato slices for a more filling plate.

Recipe Details

• Prep Time: 15 minutes
• Cook Time: 35 minutes
• Total Time: 50 minutes
• Servings: 6

Ingredients

• 1 lb salt cod, skinless and boneless
• 1 cup olive oil
• ½ cup milk or heavy cream
• 1 tbsp fresh lemon juice, or to taste
• 1 cup finely-chopped onion
• 2 cloves garlic, pressed or grated with a microplane
• Pepper

Instructions

1. Place the salt cod in a large bowl of cold water.
2. Soak for 24 hours, changing the water several times. When the fish has completely rehydrated, it is ready for the next step.
3. Poach the cod in plain water for 25 minutes or until it flakes easily when tested.
4. Drain and break it into pieces.
5. Cook the onion in olive oil over low heat until translucent.
6. In a food processor, purée the cod, onion, and garlic with half of the olive oil.
7. With the motor running add the milk or cream, rest of the oil, lemon juice and pepper.
8. Blend until smooth. If it is too thick, thin with milk or cream.
9. Serve on toast or over potato slices, coated with olive oil and roasted in a 400ºF (200ºC) oven for 30 to 40 minutes, turning once.

Variations

• Use heavy cream instead of milk for a thicker, richer finish that holds up better on toast.
• Increase the fresh lemon juice slightly if you want a sharper, brighter sauce that cuts through the olive oil more aggressively.
• Stop the food processor a little earlier for a coarser texture if you want it to feel more like a spread than a smooth cream.
• Serve it over the roasted potato slices instead of toast for a more substantial dish with a softer, starchier base.

Tips for Success

• Change the soaking water several times during the 24 hours so the salt cod loses enough salt and rehydrates evenly.
• Cook the onion over low heat only until translucent; if it browns, the sauce takes on a sweeter, heavier flavor.
• After poaching, the cod should flake easily with very little pressure. If it still feels tight, give it a few more minutes.
• Add the milk or cream and the remaining olive oil with the motor running so the mixture emulsifies into a smoother sauce.
• Thin the mixture a little at a time with milk or cream, because it is easier to loosen a thick sauce than to fix one that is too thin.

Storage and Reheating

Freezing is not ideal for this recipe. The texture can split and turn grainy when thawed.

To reheat, warm the sauce gently in a small saucepan over low heat, stirring often. You can also microwave it in short bursts at reduced power, stirring between each burst; add a small splash of milk or cream if it tightens up.

FAQ

How do you know when the salt cod has soaked long enough?

The fish should feel plump and flexible instead of stiff and dry. If you cook salt cod often, tasting a tiny piece after soaking can also help you judge the salt level.

Can you use milk instead of heavy cream?

Yes. Milk gives you a lighter, looser sauce, while heavy cream makes it thicker and richer.

Do you need a food processor for this recipe?

A food processor gives you the easiest smooth texture, but a strong blender can also work. If you use a blender, stop and scrape down the sides as needed.

Can you make it ahead?

Yes, you can make it a day in advance and refrigerate it. It will firm up as it chills, so warm it gently or let it sit at room temperature briefly before serving.
