Citric Acid Free Mediterranean Whole Roasted Fish with Herbs and Lemon
Whole roasted fish is one of those showstopper meals that looks far more impressive than the effort it actually takes, and this Mediterranean version delivers on every level. Branzino, sea bass, or red snapper all work beautifully here — their delicate, flaky flesh soaks up the garlic, rosemary, thyme, and parsley stuffed right into the cavity, so every bite is deeply fragrant and savory. The zucchini and fennel roast underneath the fish, catching all the herby drippings and turning tender and slightly caramelized in the high oven heat. For anyone navigating a citric acid sensitivity, this recipe is worth paying close attention to — the brightness here comes entirely from fresh lemon slices and wedges, which are a whole, unprocessed ingredient rather than the isolated additive found in packaged foods, sauces, and marinades. That distinction matters, and it means you can enjoy a genuinely vibrant, Mediterranean-style dish without scanning labels or second-guessing a store-bought shortcut. The olive oil, fresh herbs, and aromatics do the heavy lifting, so nothing feels stripped down or compromised. Serve it straight from the oven with a scattering of fresh parsley and you have a meal that feels celebratory enough for guests but simple enough for a weeknight.

For serving
- 1 lemon, cut into wedges, for serving

Instructions
- 1
Preheat the oven to 425°F (220°C). Toss the zucchini and fennel with 1 tbsp of the olive oil, the dried oregano, and a pinch of salt and pepper on a large rimmed baking sheet, then spread them into an even layer.

Pat the fish completely dry inside and out with paper towels. Using a sharp knife, cut 3 diagonal slashes about 1/2 inch deep through the thickest part of each fish on both sides — this helps the fish cook evenly and allows the seasoning to penetrate.
