How to Make Confit Salmon?
Confit is a technique of slow-cooking in fat at a low temperature — not frying, which uses high heat. For this recipe, the salmon fillets are submerged in olive oil flavored with lemon peel, peppercorns, and bay leaves and cooked gently until just opaque, producing an extraordinarily moist, silky texture that differs completely from pan-seared or baked salmon. If using salmon with skin, cook it skin-side down first to crisp the skin before submerging in oil.

Merkén Confit Salmon Recipe
Preparation: 45 minutes
Cooking: 70 minutes (includes overnight bean soak)
Servings: 4 people
Ingredients
1. Confit Salmon
- 800 g salmon fillets
- 2 cups olive oil
- 3 cloves garlic
- 2 bay leaves
- 1 lemon
- 1 tablespoon peppercorns
- 1 tablespoon merkén
- 1 tablespoon Cahuil salt
2. Black Bean Purée
- 180 g black beans
- 100 g bacon
- 2 bay leaves
- 1 teaspoon whole pepper
- 1 tablespoon olive oil
- A pinch of cloves
- ½ garlic head
- ½ teaspoon cinnamon
- ½ teaspoon onion powder
- Merkén
- Black pepper
- Cahuil salt
3. Bell Pepper Pebre
- 2 red bell peppers
- 2 tablespoons olive oil
- 1 tablespoon fennel
- Salt
- Pepper
Instructions
- In a large bowl, soak the beans in cold water overnight, then drain and set aside.
- Transfer the beans to a medium pot, add black pepper, bay leaves, garlic, and bacon. Cover with water and cook until the beans are tender — about 40 to 60 minutes. Remove the bacon, garlic, and bay leaves, then strain. Reserve the cooking broth.
- Process the beans in a blender or with a hand blender, adding the reserved cooking broth gradually until the mixture reaches a smooth purée consistency. Season with ground cloves, ground cinnamon, onion powder, and a tablespoon of olive oil. Mix well to integrate and adjust with salt, pepper, and a pinch of merkén. Reserve warm.
- Char the bell peppers directly over the stovetop flame or using a kitchen torch until the skin is blackened on all sides. Immediately place in a sealed zip-lock bag for 10 minutes to sweat and loosen the skin.
- Gently scrape off the charred skin with the back of a knife, remove seeds, and cut the peppers into small cubes. Add olive oil, fennel, salt, and pepper to taste, and set aside.
- In a medium skillet, heat the olive oil over medium-low heat — the oil should be warm but not smoking. Add lemon peel, peppercorns, and bay leaves. Submerge the salmon fillets in the flavored oil and cook for approximately 5 to 10 minutes, turning once, without overcooking. The fish is ready when it turns opaque throughout and flakes gently at the thickest point. Remove carefully with a spatula and drain on a paper towel. Sprinkle immediately with merkén and Cahuil salt.
- Serve the confit salmon immediately over the black bean purée with the roasted bell pepper pebre on the side.
Additional Tips
Control the oil temperature precisely — confit is slow cooking, not frying
The defining characteristic of confit technique is a low, stable oil temperature: ideally 60 to 70°C for fish. Oil at this temperature submerges the salmon in gentle heat that cooks it evenly from all sides simultaneously, producing the silky, almost translucent interior texture that defines a properly confited fish. If the oil is too hot (above 80°C), it fries the salmon rapidly — producing a firmer, more conventional texture. Use a kitchen thermometer if available, or judge by the oil surface: it should show very fine, tiny bubbles around the fish, not active sizzling.
Soak the black beans overnight — never skip this step
Dry black beans contain oligosaccharides and phytic acid on their surface that cause digestive discomfort and extend cooking time significantly. A full overnight soak (8 to 12 hours) in cold water softens the bean skin, reduces cooking time from 90 minutes to 40 to 60 minutes, and makes the beans more digestible. Drain and discard the soaking water — it contains the released anti-nutrients. If you are short on time, use the quick-soak method: boil the beans in water for 2 minutes, remove from heat, soak for 1 hour, drain, and proceed.
Char the bell pepper directly on the flame — it produces the most aromatic pebre
Direct flame charring (rather than oven roasting) creates a smoky, caramelized exterior on the bell pepper skin that infuses the flesh with a complexity that oven-roasting cannot fully replicate. The 10-minute rest in a sealed bag after charring is essential — the steam loosens the charred skin completely, making it easy to remove with the back of a knife without losing the soft, aromatic flesh underneath. Rinse briefly under cold water only if necessary to remove stubborn skin — avoid extensive rinsing, which washes away the smoke flavor.
| Ingredient | Substitution and result |
|---|---|
| Salmon fillet | Sea bass or cod — same confit technique; reduce cooking time to 6 minutes |
| Merkén | Smoked paprika + pinch of cayenne — similar smoky heat; adequate substitute |
| Cahuil salt | Fleur de sel or Maldon sea salt — same coarse finishing texture |
| Black beans | Cooked lentils or chickpeas — skip the overnight soak; purée identically |
Frequently Asked Questions (FAQs)
1. What is the difference between confit and regular frying?
Confit is slow cooking submerged in fat at a low temperature (60 to 80°C for fish). Regular frying uses high heat (160 to 180°C) for a short time. The result is completely different: fried fish has a crisped exterior and a cooked-through interior; confited fish has a uniformly silky, moist texture throughout, with no crisp crust. Confit also allows the aromatics (lemon peel, bay leaves, peppercorns) to infuse into both the oil and the fish simultaneously, producing a more complex, perfumed result than frying allows.
2. What is Cahuil salt and can I substitute it?
Cahuil salt — sal de Cahuil — is a traditional artisanal sea salt harvested from the salt flats of Cahuil on the Chilean central coast, near Pichilemu. It has a coarse, irregular crystal structure, a clean mineral flavor, and a slight grayish tint from the clay in the salt flats. It is considered one of Chile’s finest traditional ingredients. Outside Chile, fleur de sel, Maldon sea salt, or any coarse, unrefined artisanal sea salt are appropriate substitutes. Avoid using fine table salt — the texture and flavor are not equivalent.
3. Can I prepare the components in advance?
Yes — and it is recommended for a relaxed dinner service. The black bean purée can be prepared up to 2 days ahead and refrigerated, reheated gently with a splash of water or broth. The roasted bell pepper pebre keeps refrigerated for up to 3 days. The confit salmon should ideally be prepared the same day — cook it while the purée reheats. The aromatic olive oil left over from confiting can be strained and reused for sautéing or dressings — it has an excellent flavor from the lemon, bay, and peppercorns.
4. What is merkén and why is it distinctively Chilean?
Merkén — also spelled merquén — is a Mapuche spice blend made from dried, smoked cacho de cabra (goat horn) chilies, combined with toasted coriander seeds and salt. The Mapuche people of southern Chile developed this preparation as a way to preserve the harvest of dried chili peppers through smoking, which gave the spice its distinctive smokiness. Unlike chili powders from other traditions, merkén has an earthy, moderately hot, deeply smoky character with no added garlic or cumin. It was traditionally used by the Mapuche as a medicinal preparation and seasoning, and has become one of the most internationally recognized products of Chilean gastronomy.
What Is Merkén Confit Salmon?
Chilean merkén confit salmon — salmón confitado al merkén — is a gourmet preparation that applies the French confit technique to Chilean salmon, seasoned with Mapuche merkén and Cahuil artisanal salt, then served with a smoky black bean purée and roasted bell pepper pebre. It represents the contemporary expression of Chilean cuisine — traditional indigenous ingredients (merkén, Cahuil salt) applied through modern cooking techniques (confit) to Chile’s world-class farmed salmon. The three-component plate (salmon, purée, pebre) is a format typical of modern Chilean restaurant cooking that respects traditional flavors while presenting them with precision and elegance.
History of Salmon and Merkén in Chile
Salmon was introduced to Chile in the early 19th century for sport fishing purposes. Commercial aquaculture began in the 1980s and grew rapidly to establish Chile as the second largest salmon producer in the world, with the farming industry concentrated in the pristine cold fjords and lakes of southern Chilean Patagonia. Chilean farmed salmon is prized internationally for its high omega-3 content, firm texture, and color.
Merkén, by contrast, has a history that predates Spanish colonization — it was a Mapuche preparation developed over centuries in the Araucanía region of southern Chile. The combination of salmon and merkén in contemporary Chilean cooking represents the meeting of Chile’s two most internationally recognized food products: one ancient and indigenous, one modern and industrial, brought together in the cosmopolitan restaurant culture that emerged in Santiago and coastal Chilean cities from the 1990s onward.
Did You Know?
Chilean salmon has a high content of Omega-3 fatty acids, which help maintain cardiovascular health by reducing the accumulation of fats in blood vessels. Its high calcium content, combined with the naturally occurring calcitonin in fish, helps maintain skeletal health and prevents bone-density loss. Black beans, the partner ingredient in this recipe, are native to the Mesoamerican region and are particularly popular in the gastronomy of Brazil, Cuba, and Venezuela — making this dish a trans-Latin American culinary combination on a single plate.
