Oven-baked salmon is probably the best way to cook this fish without ruining it. Unlike pan-searing where the margin for error is almost zero, the oven works gently and evenly—guaranteed results. Add a creamy dill sauce and roasted potatoes, and you have a dish that impresses every time.
What strikes you first is the aroma. Fresh dill blended with cream gently reducing, the slightly lemony scent rising from the dish while the potatoes quietly turn golden on the side. When you take it all out of the oven, the salmon is pearly in the center, flakes easily with a fork. The sauce, slightly tangy, coats every bite—this is real comfort food, the kind of meal you make again the following Sunday.

Ingredient Notes
Everything you need for this creamy salmon: thick fillets, firm-fleshed potatoes, fresh dill, heavy cream, and lemon.
- Salmon fillets : Choose thick fillets, at least 3 cm. A thin fillet dries out before the potatoes are ready. The flesh should be firm and shiny, with no strong odor—that’s a sign of fresh fish.
- Fresh dill : Essential. Dried dill has neither the aroma nor the slight anise note that balances the sauce. If you really can’t find any, chives will do—but that’s a clear plan B.
- Heavy cream : No light cream here. It needs to be fatty enough not to separate when heated and to give that velvety texture that coats the salmon.
- Potatoes : Charlotte, fingerling, or Yukon Gold—firm-fleshed varieties that hold up during cooking and develop a golden crust without turning into a formless mash.
- Sweet mustard : It adds body to the sauce without overpowering. Avoid hot mustard, which would overwhelm the delicate dill flavor.
The potatoes first
Potatoes need more time than salmon—that’s the first thing to remember. Cut them into even wedges for uniform cooking, coat with olive oil, garlic powder, and thyme, then bake at 200°C. In 35 to 40 minutes, they develop a lightly golden crust and a tender interior. Flip them halfway for even browning—that simple step makes the difference between soft potatoes and truly roasted ones.
Salmon is quick to prepare
No need to marinate for hours. A few minutes suffice: a drizzle of olive oil, lemon juice, sweet paprika, salt, and pepper. The paprika adds slight depth of flavor and a golden hue on the surface during cooking. Place the fillets in the dish and let them rest while you prepare the sauce—they absorb the marinade in the meantime.
The sauce, heart of the dish
Melt the butter over low heat. Add the finely minced shallot and minced garlic, cook until translucent without browning—that takes three to four minutes, no longer. Pour in the heavy cream, stir in the sweet mustard and the juice of half a lemon, then let simmer for a few minutes until the sauce thickens slightly. Off the heat, add the chopped fresh dill. The aroma that rises at this moment—creamy, herbaceous, slightly tangy—is exactly what your kitchen should smell like.
Cooking the salmon, nothing more
12 to 15 minutes at 200°C depending on the thickness of the fillets. That’s it. The salmon is ready when it is slightly pearly in the center and flakes easily with a fork. Resist the urge to leave it longer—overcooked salmon becomes dry and stringy, and there’s no fixing that. Generously spoon the creamy dill sauce over just before serving, with a few lemon slices and extra fresh dill for freshness.
Tips & Tricks
- If your fillets are less than 2 cm thick, check for doneness at 10 minutes. Better to check early than to ruin the salmon.
- The sauce can be made ahead without issue—gently reheat over very low heat when serving; it holds up well.
- A few capers added to the sauce provide a tangy, slightly salty note that pairs perfectly with the dill.
- To amplify the flavor of the potatoes, add a pinch of smoked paprika to the seasoning—they’ll gain extra depth.
How do I know when the salmon is perfectly cooked?
The salmon is ready when it is slightly pearly and translucent in the center—not completely opaque. Gently press with a fork: if the flesh flakes easily, it’s perfect. A fully white and opaque salmon is overcooked.
Can I use light cream?
You can, but the sauce will be less velvety and may separate slightly when heated. Heavy cream has the fat content needed to withstand cooking and coat the salmon properly. To lighten it, replace half with full-fat Greek yogurt added off the heat.
Can I prepare this dish in advance?
The sauce can be made several hours ahead—gently reheat over very low heat. The potatoes can also be par-cooked and reheated in the oven for a few minutes. However, cook the salmon at the last moment: it quickly loses its tender texture when reheated.
What potato variety should I use?
Choose firm-fleshed varieties: Charlotte, fingerling, or Yukon Gold. They hold up perfectly during cooking, develop a golden crust, and won’t turn into mash. Avoid floury varieties like Bintje, which are too fragile for roasting.
Can I substitute fresh dill?
Dried dill yields a much less flavorful result—its delicate, slightly aniseed aroma largely disappears during drying. In a pinch, fresh chives are the best substitute. Flat-leaf parsley also works, but the flavor profile changes completely.
How do I store and reheat leftovers?
Store salmon and potatoes separately in the refrigerator for no more than 48 hours. Reheat potatoes in the oven at 180°C for 10 minutes to restore some crispness. For the salmon, cover with a little sauce and reheat in a very low oven (150°C, 8 minutes)—it remains edible but slightly less tender.

Instructions
- 1Preheat the oven to 200°C. Wash the potatoes and cut them into even wedges.
- 2In a bowl, toss the potatoes with 2 tablespoons of olive oil, garlic powder, thyme, salt, and pepper. Spread them on a baking sheet lined with parchment paper.
- 3Bake the potatoes for 35 to 40 minutes, turning halfway through for even browning.
- 4Place the salmon fillets in an ovenproof dish. Drizzle with the remaining 2 tablespoons of olive oil and the juice of half a lemon. Season with paprika, salt, and pepper. Let marinate while you prepare the sauce.
- 5In a saucepan over low heat, melt the butter. Add the shallot and garlic, cook for 3 to 4 minutes until translucent.
- 6Pour in the heavy cream, stir in the sweet mustard and the remaining half lemon’s juice. Let simmer over low heat for 5 minutes, stirring, until slightly thickened. Remove from heat and stir in the chopped fresh dill.
- 7About 20 minutes before the potatoes are done, bake the salmon for 12 to 15 minutes depending on thickness. The flesh should be slightly pearly in the center.
- 8Generously spoon the creamy sauce over the salmon. Serve with the roasted potatoes, a few lemon slices, and extra fresh dill.
Notes
• For perfectly cooked salmon, check at 12 minutes: the flesh should flake with a fork while still slightly pearly in the center.
• The sauce can be made ahead and gently reheated when serving—it keeps well for 24 hours in the refrigerator.
• Add a few capers to the sauce for a more tangy note that pairs well with the dill and lemon.
