Mero a la Vasca is a Basque dish of grouper (mero) fillets cooked in a sauce of garlic, parsley, white wine, and the fish's own juices, finished with a picada of crushed garlic and parsley. It is a textbook dish of traditional Basque cooking (bespoke cuisine) — clean fish, green herbs, light sauce, no cream.
Mero a la Vasca comes from the Basque coast — Getaria, San Sebastián, Bermeo — where grouper is a prized catch and besarketa cooking (traditional Basque cuisine) treats fish with restraint. The dish is built on a salsa verde base — olive oil, garlic, parsley — that defines Basque fish cookery. The picada (crushed garlic-parsley paste) stirred in at the end is what gives it the bright green color.
A wide cazuela of white fish in a glossy green sauce. The grouper is firm, sweet, and slightly gelatinous where the skin crisped. The sauce is herbaceous and garlicky, with a clean white-wine acidity. Eat it with bread and a glass of chilled txakoli.
The fish is seared skin-side down first to crisp the skin, then gently cooked in the green sauce so the flesh stays moist. The salsa verde thickens with the fish's own collagen (released from the skin and bones), giving it body without flour. Parsley goes in twice — once cooked, once raw at the end — for layered freshness.
Variations
Some use hake (merluza) instead of grouper; some add clams; the green sauce is the same base used for many Basque fish dishes.

Ingredients
Serves 4How it's made
8 steps · 35 min active + 15 min waiting
- 15 min
Have grouper filleted, skin on; cut into 4 portions; season with salt.
- 23 min
In a wide cazuela, heat olive oil; sear fish skin-side down 3 minutes until crisp; flip; remove.
Watch outSear skin-side down without moving it until the skin is crisp and releases on its own — poke too soon and it tears and sticks.
- 31 min
Add sliced garlic to the oil; cook 1 minute without browning.
- 42 min
Add flour; cook 1 minute; add white wine; reduce.
- 53 min
Add fish stock; bring to a simmer; return fish to the pan, skin-side up.
- 66 min
Cook gently 6 minutes; the sauce will thicken from the fish collagen.
Watch outSwirl the pan gently as it simmers — the sauce thickens and turns silky from the fish's own gelatin, no flour needed.
- 73 min
Make picada: crush garlic and parsley to a paste in a mortar; stir into the sauce off the heat.
Watch outStir the raw garlic-parsley picada in off the heat — boil it and you cook away the fresh, green lift.
- 83 min
Rest 3 minutes; serve in shallow bowls with the sauce spooned over.
