Spigola al forno
The simplest oven preparation — no potato bed, no parcel, nothing between the fish and the heat. Whole sea bass on a lined tray with cherry tomatoes, a garlic clove, a lemon, olive oil. Twenty minutes at high heat. The skin crisps. The flesh stays moist. The pan juices are what you pour over at the table.
This is the everyday version of the oven spigola — faster and lighter than the con patate, less assembled than the cartoccio, the preparation you choose on a Thursday evening when the fish is good and the appetite is straightforward. My mother made it when time was short or when the occasion did not call for the full potato bed production. It required nothing except a clean tray, a hot oven, and the discipline not to overcook.
The difference from the con patate preparation is structural as much as practical. Without the potato bed insulating the fish from the tray, the heat reaches the skin directly — which means the skin can crisp in a way it cannot when the fish sits elevated above an absorbent layer. A well-roasted spigola has skin that resists slightly when you press it: not leather, but taut, with a faint crunch at the surface. This happens only with a hot oven (200°C) and a fish that has been dried properly before it goes in. A wet fish steams; a dry fish roasts.
The cherry tomatoes alongside are not the protagonist here the way they are in the guazzetto. They are support — they soften, release a little liquid into the pan, and give the pan juices a faint sweetness that rounds the olive oil and lemon finish. You can omit them and the dish is still complete. You cannot omit the lemon in the cavity and the olive oil — those two, with the garlic infusing through the cooking time, are the whole flavor logic of the preparation.

Ingredients
Method
Preheat oven to 200°C fan. Line a baking tray with parchment and drizzle lightly with olive oil.
Prepare the fish. Rinse and pat completely dry inside and out with kitchen paper. Make 2–3 shallow diagonal cuts through the skin on each side. Season generously inside and out with salt and pepper. Stuff the cavity with lemon slices, a garlic half, and parsley sprigs.
Build the tray. Place the fish on the lined tray. Scatter the halved cherry tomatoes and remaining garlic around it. Add rosemary sprigs if using. Drizzle the fish and tomatoes generously with olive oil.
Roast. Place in the hot oven for 20–25 minutes depending on the size of the fish. The skin should be golden and slightly crispy. The flesh is done when it is opaque throughout and comes away from the bone when pressed at the thickest point.
Do not open the oven for the first 15 minutes. Let the heat stabilise around the fish before checking.
Rest 3 minutes and serve. Squeeze fresh lemon juice over the fish at the table. Spoon the pan juices — olive oil, tomato liquid, fish drippings — over each portion. Scatter fresh parsley.
Al forno, semplice — la spigola parla da sola.
