Cod, Olive Oil, and Cream Sauce (Brandade de Morue)

Introduction

Brandade de Morue is a French salt cod purée—silky, luxurious, and built entirely from pantry staples: salt cod, olive oil, cream, and aromatics. The long soak and poach transform tough, preserved fish into tender flakes that blend into a cloud-like spread. Serve it warm on toast or spooned over roasted potatoes for a dish that feels restaurant-quality but takes no special skill.

Recipe Details

• Prep Time: 30 minutes (plus 24 hours soaking)
• Cook Time: 40 minutes
• Total Time: 24 hours 70 minutes
• Servings: 4

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

With Potato: Boil 1 lb waxy potatoes until tender, peel, and fold into the purée at the end instead of serving separately. This creates a thicker, more cohesive spread.

With Garlic Oil: Replace the plain olive oil drizzle on potatoes with garlic-infused oil (warm ½ cup olive oil with 4 sliced garlic cloves for 10 minutes, then strain). It adds aromatic depth without extra steps.

Lighter Version: Substitute half the cream with chicken or vegetable broth. You’ll lose some richness but gain a brighter, less heavy texture that still spreads easily.

With Roasted Garlic: Roast 6 cloves garlic in a small pan with olive oil until golden and soft, then add to the food processor. This mellows the garlic bite and adds subtle sweetness.

With Thyme: Steep 2 sprigs fresh thyme in the cream for 10 minutes before adding to the processor, then discard. It introduces herbal complexity without changing the cooking method.

Tips for Success

Change your soaking water at least three times over the 24 hours. Salt cod is intensely brined; incomplete desalting makes the finished dish inedible.

After poaching, taste a flake before blending. If it still tastes very salty, poach for another 10 minutes and drain again.

Add cream and oil slowly while the motor runs. Rapid addition can break the emulsion and leave you with a grainy texture instead of a smooth purée.

Don’t overblend once the purée comes together. Stop as soon as it reaches a thick, spreadable consistency; extra processing can make it gluey.

If you’re making this ahead, store it in an airtight container in the fridge and gently reheat in a small pot over low heat with a splash of milk to loosen it back to serving consistency.

Storage and Reheating

Store brandade in an airtight container in the refrigerator for up to 4 days. It does not freeze well—the emulsion breaks down and the texture becomes grainy when thawed.

Reheat on the stovetop over low heat, stirring often and adding a tablespoon or two of milk or cream to restore its smooth, spreadable consistency. Microwave reheating is possible but risks uneven heat and can separate the mixture; if you use a microwave, heat in 30-second intervals, stirring between each one.

FAQ

Can I use fresh cod instead of salt cod?

No. Salt cod’s texture and flavor are essential to the dish. Fresh cod will not produce the same meaty, structured result. If salt cod is unavailable, this recipe does not translate to a satisfactory substitute.

What if the purée breaks or looks grainy?

Stop blending immediately and let it rest for a few minutes. If separation has already occurred, transfer to a bowl, whisk in a tablespoon of cream, and stir by hand until the texture smooths. Over-processing or adding ingredients too quickly are the usual culprits.

Can I make this without a food processor?

Yes, but it requires elbow work. After poaching, chop the cod very finely, then use a mortar and pestle or wooden spoon to mash it with the cooked onion and garlic until it breaks down. Add oil and cream gradually, stirring constantly until smooth. It will take 15–20 minutes of hand-mashing.

Is this recipe dairy-free?

No, and it cannot be made dairy-free without fundamentally changing the dish. Cream is structural; it emulsifies with the oil to create the signature silky texture. A non-dairy substitute will not bind properly.
