Mussels: A Seafood Delight Worth Savoring – Health Benefits and Recipes
September 25, 2024Mussels Around the World: How Different Cultures Prepare and Savor Them
Mussels are one of the most widely eaten shellfish in the world — they appear in the cuisines of Belgium, France, Spain, Italy, Thailand, New Zealand, Chile, and dozens of other countries. Each culinary tradition has developed distinct preparations that reflect local ingredients, flavor preferences, and cooking techniques. This guide covers six of the most distinctive international mussel preparations — from the Belgian classic that made mussels famous globally to the Thai mussel salad that is one of the most refreshing shellfish dishes in Southeast Asian cuisine.

1. Belgium and France: Moules-Frites
Moules-frites — mussels with French fries — is the national dish of Belgium and one of the most iconic seafood preparations in the world. Belgium consumes more mussels per capita than any other country in Europe, and moules-frites is served in virtually every Belgian brasserie. The mussels are steamed in white wine (or beer, in some Belgian preparations), shallots, garlic, and herbs; the fries are cooked twice (once at lower temperature to cook through, once at high temperature to crisp) and served with mayonnaise. The combination of the briny, aromatic mussel broth and the crispy, salty fries is one of the great flavor pairings in European cuisine.
Key characteristics: white wine or Belgian beer broth; shallots and celery as aromatics; crème fraîche finish (in the French moules marières version); served with twice-fried frites and mayonnaise; eaten with a mussel shell used as a pincer to extract the meat from other shells
Regional variations: moules à la bière (Belgian beer instead of wine); moules à la crème (cream-based broth); moules provencales (tomato, garlic, olive oil, herbs de Provence)
2. Spain: Mejillones en Escabeche
Spain is one of the world’s largest mussel producers (Galicia, in northwestern Spain, produces approximately 250,000 tons of mussels per year — more than any other region in Europe). The most distinctive Spanish mussel preparation is mejillones en escabeche — mussels preserved in a vinegar-based marinade with olive oil, garlic, bay leaf, paprika, and sometimes saffron. The escabeche technique (cooking in an acidic marinade) is an ancient Spanish preservation method that also adds flavor. Mejillones en escabeche are served at room temperature as a tapa, often from a tin (canned mejillones en escabeche are a Spanish pantry staple and are considered a premium product). The flavor is tangy, smoky (from the paprika), and intensely savory.
Key characteristics: vinegar and olive oil marinade; smoked paprika (pimentón de la Vera); bay leaf and garlic; served at room temperature as a tapa; often canned and served directly from the tin with toothpicks; pairs with crusty bread and a cold glass of Albariño or Txakoli
How to make a simplified version at home: steam mussels open; remove from shells; combine ½ cup olive oil, ¼ cup white wine vinegar, 2 garlic cloves (thinly sliced), 1 tsp smoked paprika, 2 bay leaves, and a pinch of saffron in a small saucepan; warm over low heat for 5 minutes; pour over the shelled mussels; cool to room temperature; refrigerate for at least 2 hours before serving; keeps for up to 5 days refrigerated
3. Italy: Cozze alla Tarantina
Cozze alla tarantina is the mussel preparation of Taranto, a port city in Puglia (southern Italy) that has been a center of mussel cultivation since Roman times. The preparation is simple: mussels are opened on the half shell (raw, not steamed), topped with a mixture of breadcrumbs, garlic, parsley, olive oil, and sometimes Pecorino, and baked or grilled until the topping is golden. The result is similar to Clams Casino but with a distinctly Italian flavor profile — the breadcrumb topping is more herb-forward and olive oil-based rather than bacon-based. Cozze alla tarantina is served as an antipasto and is one of the most celebrated dishes of Pugliese cuisine.
Key characteristics: mussels opened raw on the half shell (not pre-steamed); breadcrumb, garlic, parsley, and olive oil topping; sometimes Pecorino Romano; baked or grilled until golden; served as an antipasto; the raw opening technique requires a mussel knife and some practice
Note on the raw opening technique: insert a thin knife into the seam of the shell near the hinge; twist to pry open; sever the adductor muscle; discard the top shell; the mussel remains raw in the bottom shell; top with the breadcrumb mixture and bake at 450°F for 8–10 minutes
4. Thailand: Hoi Malaeng Puu Ob Wun Sen (Mussels with Glass Noodles)
Thai cuisine uses mussels in several preparations, but the most distinctive is hoi malaeng puu ob wun sen — mussels steamed with glass noodles (mung bean vermicelli), ginger, lemongrass, garlic, and oyster sauce, cooked in a clay pot. The glass noodles absorb the mussel cooking liquid and the aromatics, becoming intensely flavored and silky. The dish is finished with fresh cilantro and a squeeze of lime. It is a complete one-pot meal that is simultaneously light and deeply savory. A simpler Thai mussel preparation is hoi malaeng puu pad cha — mussels stir-fried with Thai basil, galangal, kaffir lime leaves, and fresh chilies in a very hot wok; the high heat chars the aromatics slightly and creates a smoky, intensely fragrant dish.
Key characteristics of ob wun sen: clay pot cooking; glass noodles (mung bean vermicelli); ginger, lemongrass, garlic, oyster sauce; finished with cilantro and lime; the noodles absorb the mussel liquid and become the star of the dish
Key characteristics of pad cha: very high heat wok cooking; Thai basil, galangal, kaffir lime leaves, fresh chilies; the high heat creates a slightly charred, smoky quality; served with jasmine rice
5. New Zealand: Green-Lipped Mussels
New Zealand’s green-lipped mussel (Perna canaliculus) is a distinct species from the blue mussel (Mytilus edulis) common in Europe and North America. Green-lipped mussels are significantly larger (up to 6 inches), have a distinctive green edge on the shell, and have a richer, more robust flavor than blue mussels. New Zealand is the world’s largest producer of green-lipped mussels, and they are exported globally both fresh and frozen on the half shell. The most common New Zealand preparation is simple: steamed or grilled on the half shell with a compound butter (garlic, parsley, lemon zest) or a light vinaigrette. Green-lipped mussels are also sold as a dietary supplement (freeze-dried powder) for their high omega-3 and glycosaminoglycan content, which has been studied for joint health benefits.
Key characteristics: larger size (up to 6 inches); green edge on the shell; richer, more robust flavor than blue mussels; commonly sold frozen on the half shell; simple preparations (compound butter, vinaigrette) that let the mussel’s flavor dominate; also available as a dietary supplement
6. Chile: Choritos al Vapor con Pebre
Chile has one of the longest coastlines in the world and a rich shellfish culture. The Chilean mussel (Mytilus chilensis) is a close relative of the European blue mussel and is farmed extensively in the Los Lagos region of southern Chile. The most common Chilean preparation is choritos al vapor — mussels steamed in white wine or beer with garlic and herbs — served with pebre, the Chilean condiment made from fresh tomatoes, onion, cilantro, garlic, olive oil, and aji (fresh chili). The pebre’s acidity and heat contrast with the mussels’ brininess in the same way that salsa contrasts with seafood in Mexican cuisine. Choritos are also used in curanto — the traditional Chiloé island feast where shellfish, meat, and potatoes are cooked together in a pit lined with hot stones.
Key characteristics: steamed in white wine or beer; served with pebre (fresh tomato, onion, cilantro, garlic, olive oil, aji); the pebre’s acidity and heat contrast with the mussels’ brininess; also used in curanto (traditional pit-cooked feast)

FAQs: Mussels in World Cuisines
What makes Belgian moules-frites different from French moules marinières, and which is the original?
Moules-frites (mussels with fries) is Belgian; moules marières (mussels in white wine and cream) is French — they are related but distinct: (1) Moules-frites: the Belgian national dish; the mussels are steamed in white wine or Belgian beer with shallots, celery, and herbs; the defining element is the pairing with twice-fried frites and mayonnaise; the fries are as important as the mussels; (2) Moules marières: the French preparation; the mussels are steamed in white wine (traditionally Muscadet) with shallots, garlic, celery, thyme, and bay leaf; finished with crème fraîche; served with crusty bread rather than fries; the broth is richer and more complex than the Belgian version. Which is the original: both traditions are old and the exact origin is disputed; Belgium claims moules-frites as a national dish dating to the 18th century; the French moules marières tradition is similarly old. Both are excellent — the Belgian version is more casual and filling; the French version is more refined.
What are green-lipped mussels, and are they nutritionally different from regular blue mussels?
Green-lipped mussels (Perna canaliculus) are a distinct species native to New Zealand, significantly larger than the blue mussel (Mytilus edulis) common in Europe and North America. Nutritional differences: (1) Omega-3s: green-lipped mussels contain a unique omega-3 fatty acid called ETA (eicosatetraenoic acid) that is not found in significant quantities in blue mussels; ETA has been studied for anti-inflammatory properties, particularly for joint health; (2) Glycosaminoglycans: green-lipped mussels are a source of glycosaminoglycans (GAGs), including chondroitin sulfate, which are components of cartilage; this is the basis for green-lipped mussel supplements marketed for joint health; (3) General nutrition: both species are similar in protein, B12, iron, selenium, and zinc content; green-lipped mussels are slightly larger and have more meat per shell. The joint health supplement evidence is mixed — some studies show modest benefits for osteoarthritis; the evidence is not conclusive enough to make strong claims.
What is escabeche, and how does the Spanish mejillones en escabeche preparation work?
Escabeche is an ancient Spanish (and Portuguese) preservation technique in which cooked food is marinated in an acidic mixture (vinegar, citrus juice, or wine) with olive oil, aromatics, and spices. The acid inhibits bacterial growth and extends the shelf life of the food; the marinade also adds flavor. For mejillones en escabeche: (1) mussels are steamed open and removed from their shells; (2) a marinade is made from olive oil, white wine vinegar, garlic, smoked paprika (pimentón), bay leaf, and sometimes saffron; (3) the marinade is warmed (not boiled) to bloom the spices; (4) the shelled mussels are submerged in the warm marinade and cooled to room temperature; (5) the mussels are refrigerated for at least 2 hours (ideally overnight) before serving; the flavor improves with time. The result is tangy, smoky, and intensely savory — one of the most distinctive mussel preparations in the world. Canned mejillones en escabeche (from Galicia) are considered a premium product and are served directly from the tin as a tapa.
