Salmon Florentine

Dinner

Salmon fillets seared until golden, then nestled into a silky sauce of cream, white wine and wilted spinach. This is saumon à la Florentine, a proper French bistro dish that looks impressive but takes about half an hour from start to finish. One pan. Minimal washing up. Maximum smugness.

For the salmon

• 4 salmon fillets (about 150g each), skin on
• 1 tbsp olive oil
• salt and black pepper

For the sauce

• 30 gr unsalted butter
• 2 shallots
• 3 cloves garlic
• 100 ml dry white wine
• 250 ml Double cream
• 200 gr baby spinach
• ¼ tsp nutmeg
• 1 squeeze lemon juice
• 1 handful flat-leaf parsley
• salt and black pepper

Equipment

1 braisière shallow dutch oven

knife

chopping board

double spatula

Instructions

1. Season and sear the salmon

• Take the salmon out of the fridge about 15 minutes before cooking, room temperature fish cooks more evenly. Pat the fillets dry with kitchen paper and season generously with salt and pepper on both sides.

  Heat the olive oil in a shallow dutch oven over medium-high heat. When the oil shimmers, lay the salmon fillets in skin-side down. Don't touch them. Let them sizzle undisturbed for 3-4 minutes until the skin is crispy and golden, and you can see the flesh has turned opaque about two-thirds of the way up the sides. Flip briefly to sear the top (just 30 seconds or so) then transfer to a plate. The salmon won't be cooked through at this point, and that's fine. It'll finish in the sauce.

2. Build the sauce base

• Turn the heat down to medium and add the butter to the same pan. Once it's foaming, add the shallots and cook gently for 3-4 minutes until soft and translucent. Don't let them colour. Add the garlic and cook for another minute until fragrant.

  Pour in the white wine and let it bubble away for a couple of minutes, scraping up any golden bits stuck to the bottom of the pan. This is where a lot of the flavour lives, so don't skip the scraping.

3. Add the cream and spinach

• Pour in the double cream, stir well, and let it come to a gentle simmer. Add the spinach in handfuls, stirring each addition until wilted before adding more. It looks like a ridiculous amount at first, but it collapses down to almost nothing within seconds.

  Season with the nutmeg, a squeeze of lemon juice, and salt and pepper to taste. The nutmeg is traditional with spinach in French cooking, it lifts everything without being identifiable. Go easy though; you want a hint, not a Christmas candle.

4. Finish the salmon in the sauce

• Nestle the salmon fillets back into the sauce, skin-side up this time to keep it crispy. Spoon some of the creamy spinach mixture over the tops of the fillets. Cover the pan with a lid and cook over low heat for 5-7 minutes, until the salmon is just cooked through. It should flake easily but still be slightly translucent in the very centre, it'll carry on cooking from residual heat.

5. Serve

• Scatter over the parsley and bring the whole pan to the table. Serve straight from the pan with crusty bread to mop up the sauce, or alongside new potatoes or rice.

Notes

• Use wine for the sauce you’d actually drink, a dry white like Muscadet, Sauvignon Blanc, or an inexpensive Chablis. Avoid anything too oaky or it’ll overpower the delicate sauce.
• Baby spinach wilts fastest and has the mildest flavour. You can use regular spinach but remove the tough stems first. Frozen spinach works in a pinch, thaw and squeeze out excess water before adding.
• Stir in a tablespoon of Dijon mustard with the cream for a sauce moutarde variation, or add a handful of grated Gruyère at the end for a proper gratin finish.
• Skin on or off? Skin-on salmon gives you that gorgeous crispy texture contrast. If your fishmonger has skinned them already, sear the fish for slightly less time on the first side.
• Don’t overcook the salmon: The biggest mistake people make with salmon is cooking it to death. It should still have a blush of pink in the centre when you take it off the heat.

About this recipe

In French cooking, when you see something “à la Florentine,” it means spinach is involved. It sounds Italian, but the term is thoroughly French, and it is named more for a person and a story than for the city itself. This salmon Florentine is salmon with you guessed it, spinach.

Where the Florentine name comes from

The term goes back to 1533, when Catherine de Medici of Florence married Henry II of France. The usual story says she arrived in Paris with her own chefs, equipment, and a serious love of spinach, and that she single-handedly popularised Florentine-style dishes at court. Historians have mostly pulled that apart by now. Italian influence on French cooking was already there well before she arrived, and the French court was already soaking up Renaissance ideas from across the Alps. Catherine certainly played a role, but the spinach connection has probably been exaggerated over time into something more dramatic than it really was.

What matters is that the name stuck. Any dish served on a bed of spinach, often with a cream sauce, picked up the Florentine label: eggs Florentine, sole Florentine, chicken Florentine. It has been part of French kitchen language for almost five hundred years.

Auguste Escoffier included a sole Florentine in his 1903 Le Guide Culinaire. In his version, the fish is poached, the spinach is cooked separately in butter, everything is covered in Mornay sauce, and the dish is finished under the grill until the top is golden. It is a more formal, multi-step affair than this salmon Florentine recipe, but the bones are the same: fish, spinach, cream, and a blast of heat at the end. Escoffier’s take needs three separate components. This one does it all in a single pan.

This creamy salmon florentine

This recipe takes the traditional idea and trims it down for a weeknight without losing what makes the dish worth cooking. The salmon is seared first so it develops a golden crust, which adds flavour and stops it turning pale and poached-soft in the sauce. It then finishes gently in the Florentine sauce so the inside stays silky instead of turning firm and rubbery.

The spinach wilts straight into the pan; you do not need a second pot. It is exactly the kind of easy salmon Florentine French home cooks have been making for years, even if restaurant versions look fussier and involve more moving parts.

A little nutmeg with spinach is classic French practice. You see it in gratin dauphinois, in béchamel, and anywhere leafy greens meet cream. You only need a light grating. Too much and it takes over. Just enough makes the spinach taste somehow more like itself, which is really the point.

The Florentine sauce for salmon

A good Florentine sauce for salmon is a reduced cream sauce built on shallots, white wine, and careful seasoning, sturdy enough to stand alongside both the salmon and the cream. It is not a béchamel, not a velouté, just a direct reduction that concentrates flavour and coats the fish without feeling heavy.

You start with shallots softened gently in butter until they are completely tender. Then in goes the white wine, which you reduce by about half. After that, add the cream and let it simmer until it lightly coats the back of a spoon. That is the entire structure of the sauce: three ingredients and some patience.

The one thing to watch is not letting it go too far before the salmon returns to the pan. If cream reduces too hard for too long, it can split into fat and liquid and you lose that smooth, silky texture that makes salmon Florentine so satisfying. Take the pan off the heat as soon as the sauce looks glossy and thick enough. The remaining warmth of the pan and the fish will bring it to exactly where it needs to be.

The right pan

This easy salmon Florentine behaves best in a wide, shallow pan that holds heat evenly and gives the spinach space to wilt into the sauce. I like the Staub cast iron shallow braiser for this. The broad base gives the salmon room to sear properly rather than steam. The cast iron spreads heat evenly so the sauce reduces at the same pace across the pan instead of catching in one hot spot, and the shallow sides make it easy to fold the spinach through the sauce without it spilling. It also goes straight from stove to table, which is exactly how a dish like this should be served.

Choosing the right salmon

Because the sauce is simple and clean, the quality of the salmon really shows. Centre-cut fillets are the best choice. Their even thickness means they cook at the same rate from end to end, and that central section has a slightly higher fat content than the tail, which gives you a richer, more tender result.

Skin on or off is entirely up to you. I love it, but my husband gives his to me. Skin on lets you get a crisp first side, which adds another layer of texture. Skin off means the flesh is in direct contact with the sauce on both sides and soaks up more flavour. Both approaches work. The crucial part is that the salmon meets a properly hot pan, not just a warm one.
