Baked Cod with Fresh Herb Sauce

Cod is one of those fish that forgives a busy evening. It is mild, it flakes into clean white pieces, and it takes on whatever you put next to it. This recipe leans on that. The fish itself gets only a drizzle of olive oil and a short stretch in a hot oven, so most of the flavor comes from the sauce, which is simply parsley and cilantro whizzed with garlic, red onion, lime, and a splash of red wine vinegar.

Herb sauces like this one have a long history around the Mediterranean and Latin America, where cooks have spooned bright, raw green sauces over grilled and baked fish for generations. Chimichurri is the most famous cousin, and the idea is always the same: fresh herbs chopped fine, sharp acid, a little heat, and good oil to bind it. Parsley brings a clean, grassy note, and cilantro brings a citrusy lift that pairs well with lime. If you have never tried the two together, this is a good place to start.

A food fact worth knowing: cod is a lean white fish, and fish in general cooks quickly. The 145°F target in the recipe is the point where the flesh turns opaque and separates easily with a fork. Pull it just there. Fish keeps cooking on the plate for a minute or two, so a slightly early exit from the oven is a good habit.

For the sauce, use the food processor as the recipe suggests, but stop once it is smooth and spoonable rather than running it into a paste. A little texture from the chopped onion keeps it lively. If you find the raw garlic too sharp, let the sauce sit for ten minutes before serving. The vinegar and lime mellow it, and the flavor settles into something rounder.

Leftovers are simple to handle. Keep the cooked cod in a sealed container in the fridge and eat it within a day or two. The herb sauce keeps a little longer if you cover the surface with a thin film of oil, though the color will darken slightly. Flaked cod is also lovely cold, tossed into a green salad the next day with the sauce loosened by an extra spoon of lime juice.

What to serve alongside? Something warm and earthy balances the bright sauce. Roasted vegetables work well here, and a tray of garlicky lime roasted broccoli florets Garlicky Lime Roasted Broccoli Florets would echo the citrus without crowding the plate. For something heartier, try Roasted Sweet Potato Salad with Avocado, which adds sweetness and creaminess next to the fish. If you want a vegetable that brings crunch, Crispy Roasted Brussels Sprouts with Smoky Chipotle Dip makes a satisfying companion.

Keep the rest of the plate simple, and let the green sauce do the talking.
