It also happens to be keto, pescatarian, and packed with 55% of your daily vitamins. Ninety percent spoonacular score, 45 minutes, and $8.86 per serving – this is date night material.

“I made this for our anniversary and my husband thought I'd spent hours on it. The salmon was the most tender I've ever had, and the lemongrass sauce is absolutely divine. It's now our special‑occasion meal.”
What Is Salmon Confit?
Confit (pronounced kon‑fee) is a traditional French technique where food is slowly cooked in fat at a low temperature. For salmon, this usually means submerging the fillets in olive oil or another high‑quality oil and cooking them gently in a low oven or on the stovetop. The result is fish that's cooked through but still impossibly moist, with a texture that's almost buttery. It's forgiving, too – because the temperature stays low, you have a wide window of doneness. No more dry, overcooked salmon.
The lemongrass sauce is the perfect partner. Lemongrass brings a bright, citrusy, slightly floral note that cuts through the richness of the confit. Combined with garlic, a little ginger, and a splash of coconut milk, it becomes a silky, aromatic sauce that you'll want to put on everything. Each serving delivers 46 grams of protein, 68 grams of healthy fat (mostly from the salmon and oil), and a remarkable 55% of your daily vitamins and minerals. At 865 calories, it's a substantial meal that will keep you satisfied for hours.

Ingredient Notes
Salmon. Wild‑caught salmon has better flavor and texture, but high‑quality farmed salmon works too. Look for fillets of even thickness so they cook evenly.
Oil. You don't need the most expensive olive oil for confit – a good quality but reasonably priced oil is fine. The oil can be strained and reused for roasting vegetables or making dressings.
Lemongrass. Fresh lemongrass is essential here. Dried or powdered lemongrass won't give you the same bright, aromatic flavor. If you can't find it, substitute lemon zest and a little ginger, but it won't be quite the same.
How to Make Salmon Confit with Lemongrass Sauce
1. Prepare the Salmon
Pat the salmon fillets dry and season generously with salt and white pepper. Let them sit at room temperature for 15 to 20 minutes while you prepare the oil.
2. Make the Confit
Preheat your oven to 225°F (or prepare a stovetop setup). Place the salmon in a small ovenproof dish or saucepan where they fit snugly in a single layer. Add the smashed garlic and herbs if using. Pour the oil over the salmon until they're completely submerged. (Don't worry – you can reuse the oil later.)
Transfer to the oven and cook for 25 to 30 minutes, until the salmon is just opaque and flakes easily with a fork. Alternatively, cook on the stovetop over the lowest possible heat, maintaining a temperature of around 150°F.
3. Make the Lemongrass Sauce
While the salmon cooks, make the sauce. Heat 1 tablespoon of oil in a small saucepan over medium heat. Add the shallot, lemongrass, garlic, and ginger. Cook, stirring, until softened and fragrant, about 3 minutes.
Add the coconut milk, chicken stock, fish sauce, and brown sugar (if using). Bring to a simmer and cook for 5 to 7 minutes, until slightly thickened. Stir in the lime juice. Taste and adjust seasoning with salt or more lime juice. Keep warm.
4. Serve
Carefully lift the salmon from the oil with a slotted spatula and drain briefly on paper towels. Place each fillet on a warm plate. Spoon the lemongrass sauce around (not over) the salmon to keep the skin crisp if you left it on. Serve immediately with steamed rice, vegetables, or a simple salad.
🔥 Pro Tips for Perfect Salmon Confit
- Save the oil. Strain the used oil through a fine‑mesh sieve and store it in the fridge. It's now infused with salmon and herbs – incredible for roasting potatoes or vegetables.
- Don't rush. Low and slow is the whole point. If your oven runs hot, check early. The salmon should be just cooked through, not falling apart.
- Make it ahead. You can confit the salmon up to a day in advance and store it in the fridge, submerged in the oil. Gently reheat in a low oven.
- Double the sauce. The lemongrass sauce is incredible on rice, vegetables, or even grilled chicken. Make extra.
Serving Suggestions
This salmon is rich and satisfying. Pair it with:
- Steamed jasmine rice or cauliflower rice. To soak up every drop of that lemongrass sauce.
- Lightly sautéed bok choy or asparagus. A simple green vegetable balances the richness.
- A crisp cucumber salad. Tossed with rice vinegar, a little sugar, and chili flakes.
- A glass of dry Riesling or Sauvignon Blanc. The acidity cuts through the fat beautifully.
Recipe Variations
Once you've mastered the classic, try these twists:
- Citrus Confit Salmon: Add strips of orange or lemon zest to the confit oil. Serve with a simple citrus vinaigrette.
- Salmon Confit with Dill and Mustard Sauce: Replace the lemongrass with fresh dill in the sauce, and add a spoonful of whole‑grain mustard.
- Poached Salmon with Artichoke Confit: Poach the salmon gently in broth and serve with artichoke hearts confit in olive oil with herbs.
- Spicy Lemongrass Sauce: Add a minced Thai chili or a spoonful of sambal to the sauce for heat.
Storage and Leftovers
Leftover confit salmon is incredible. Store it in the fridge, submerged in its oil, for up to 3 days. Use it on salads, in sandwiches, or simply flaked over rice. The lemongrass sauce keeps in the fridge for up to a week – reheat gently or serve at room temperature.
