Sformato di tonno (Baked Tuna Mold)

Ingredients

• 500 g (1 lb, as listed)ricotta cheese (one small container)
• 2 cansgood-quality tuna, preferably packed in olive oil (see Notes)
• 3 (or more—see Notes)eggs
• 50–100 g (2–3 oz), or more to tastefreshly grated Parmesan cheese
• to tastesalt and pepper
• as neededolive oil

Instructions

1. 1

   Mix the ingredients

   Combine all the ingredients in a bowl and mix until evenly incorporated. Season very generously with salt and pepper.

2. 2

   Prepare the tin

   Coat the sides of a small loaf tin, preferably non-stick, with olive oil, then pour in the mixture.

3. 3

   Make a water bath

   Set the loaf tin inside a larger baking tin. Add enough water to reach at least about 1.3 cm (½ inch) up the sides of the loaf tin.

4. 4

   Bake until set

   Put both tins in an oven preheated to 180°C (350°F) and bake for about 30 minutes, adjusting for the loaf tin’s size and shape. The mixture should not wobble when you shake the tin, and a skewer or knife inserted into the top should come out clean.

5. 5

   Cool the sformato

   Lift the loaf tin out of the water bath and leave the sformato to cool for at least 15 minutes; it can cool completely if you prefer.

6. 6

   Turn out and serve

   Place the tin on a cutting board or serving platter. Hold the tin and board or platter firmly together, turn them over, and shake the tin gently to release the sformato. Remove the tin, slice the loaf and serve on a platter or individual plates, plain or with a little tomato sauce.

What is sformato di tonno?

Sformato is the Italian name for a moulded savoury preparation, often baked and turned out before serving. This version combines tuna with ricotta, eggs and Parmesan for a soft, sliceable loaf.

The recipe’s water bath helps the mixture cook gently, while the cheese and eggs give it enough structure to unmould. It is simple enough to make ahead and serve either warm or cool.

Nutrition and macros by portion

The nutrition label shows one serving as written: 475 calories, 40g protein, 5g carbs, 33g fat.

Ricotta, olive-oil-packed tuna, eggs and Parmesan contribute most of the energy and fat; tuna, eggs, ricotta and Parmesan provide the protein. The small amount of carbohydrate comes mainly from the dairy. Balance a slice with a generous serving of salad or vegetables.

Choose the tuna and ricotta

Tuna: Good-quality tuna packed in olive oil gives the loaf a fuller flavour. Drain it if there is excess oil, but keep the tuna in distinct flakes rather than mashing it to a paste.

Ricotta: Use a small container as specified and stir it smooth if it is lumpy. A very wet ricotta can make the mixture looser, so drain off any pooled liquid before mixing.

Season and mix

Cheese: Freshly grated Parmesan adds savouriness and salt, so taste the mixture before adding salt if you can. The recipe calls for generous seasoning, but the amount needed depends on the tuna and cheese.

Eggs: Three eggs are the stated starting point, with the option to use more as noted in the original recipe. Mix thoroughly so the ingredients are evenly distributed, without beating in lots of air.

Why use a water bath?

The surrounding hot water moderates the heat reaching the loaf tin and encourages the egg-based mixture to set gently. Make sure the larger tin is stable before adding water, and take care when moving it into the oven.

Check the centre

Timing: The recipe gives about 30 minutes at 180°C, but the tin’s dimensions affect how quickly the centre cooks. Begin checking around that point rather than relying on the clock alone.

Doneness: The loaf should hold still when the tin is shaken, and a skewer or knife inserted into the top should come out clean. A small test mark on top will be hidden when the sformato is turned out.

Cool before unmoulding

Resting: Leave the loaf in its tin for at least 15 minutes after removing it from the water bath. Cooling helps it firm up and makes it easier to turn out in neat slices.

Turning out: Hold the tin and board firmly together as you invert them, then give the tin a gentle shake. If it resists, avoid forcing it; loosen the edges carefully and try again.

How to serve it

Serve slices plain or with a little tomato sauce, as the recipe suggests. A crisp green salad or simply cooked vegetables make a fresh contrast to the rich, savoury loaf.

Recipe notes & tips

• Use a small loaf tin so the mixture has enough depth to turn out as a loaf.
• Grease the sides of the tin thoroughly to help the sformato release.
• Add the water to the larger tin carefully to avoid splashing it into the mixture.
• Let the loaf rest for longer than 15 minutes if you want it completely cool before slicing.
• Use a clean skewer or knife to check the centre, since the baking time depends on the tin.

Variations

• Tomato sauce: Serve each slice with a little tomato sauce, as suggested in the recipe.
• More Parmesan: Increase the freshly grated Parmesan to taste for a more pronounced savoury flavour.
• Extra egg: Use more than three eggs if following the recipe’s suggested option in the Notes.
• Olive-oil tuna: Choose tuna packed in olive oil for a fuller-tasting loaf.
• Chilled slices: Cool the sformato completely before slicing it for a firmer texture.

Common mistakes to avoid

• Skipping the water bath: The loaf may cook less gently; use a larger tin with water around the base of the loaf tin.
• Under-greasing the tin: The sformato can stick; coat the sides well with olive oil.
• Relying only on the timer: Tin size changes the cooking time; check for a set centre and a clean skewer.
• Turning it out too soon: A hot loaf may break; cool it for at least 15 minutes first.
• Adding water carelessly: Water can splash into the mixture; pour it slowly into the larger tin.

How to store

Refrigerate leftovers in a covered container and eat within 3 days. Serve chilled or reheat gently in a low oven until warmed through; avoid overheating, which can make the loaf firm.
