Whole roasted fish is one of those showstopper meals that looks far more impressive than the effort it actually takes. Two beautiful fish — branzino, sea bass, or red snapper all work wonderfully — get stuffed with lemon rounds, fresh thyme, rosemary, garlic, and parsley before hitting a hot oven alongside a bed of sliced zucchini and fennel. The result is fragrant, herb-forward, and deeply satisfying in that clean, coastal way that makes you feel like you're eating somewhere with a view of the sea. Scoring the fish before roasting is a small but smart step that helps the seasoning penetrate all the way through and ensures even cooking from edge to center. Because the flavor here comes entirely from fresh herbs, citrus, good olive oil, and simple aromatics, there's no need to scan labels or worry about spice blends sneaking in anything unwanted — every ingredient is exactly what it says it is. The roasted fennel and zucchini soak up all those savory juices from the fish and become something genuinely special on their own. Finish with a squeeze of fresh lemon and a scatter of parsley, and dinner is done.

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.
