Suppli al Telefono (Roman Fried Rice Balls)
Why this recipe works
- Savoury depth: Butter-softened onion, white wine, tomato passata, and parmesan give the rice a rounded, savoury base before it is shaped.
- Crisp shell: A double coating of egg and breadcrumbs creates a sturdy crust that contrasts with the soft rice and molten cheese.
- Classic mozzarella pull: Chilling the rice before shaping helps seal the mozzarella inside, so it melts cleanly and stretches when served hot.

Authenticity notes
- Roman street-food style: Supplì are closely associated with Rome, where they are commonly served as a snack, antipasto, or casual fried bite.
- The ‘al telefono’ effect: The name refers to the thin string of hot mozzarella that stretches between the two halves when a freshly fried supplì is pulled apart.
- Common variations: Some versions include meat ragù, but a tomato rice and mozzarella filling still gives the recognisable Roman character.
Texture tips
- Chill until firm: The rice should be completely cold and firm before shaping; warm rice is harder to seal and more likely to split.
- Press the crumbs on well: A firmly pressed breadcrumb coating helps the crust adhere during frying and gives a more even crunch.
- Keep the oil steady: Fry at 175°C (345°F) and let the oil recover between batches so the coating crisps quickly rather than absorbing excess oil.
Make-ahead tips
- Cook the rice ahead: The tomato rice can be made and chilled in advance, which also makes it easier to portion and shape.
- Shape before frying: Form and crumb the supplì ahead of cooking, then keep them chilled until ready to fry.
- Freezer-friendly once cooked: Cooked supplì can be frozen, then reheated from frozen on a baking tray at 200°C (390°F) until piping hot.
Ingredient swaps
- Without wine: Replace the white wine with water, adding it gradually and cooking until the rice is tender and thick.
- Alternative hard cheese: Grana Padano can be used instead of parmesan for a slightly milder, sweeter savoury finish.
- Lower-leakage mozzarella: Low-moisture mozzarella gives a firmer centre and can help reduce cheese leakage during frying.

Ingredients
Instructions
- Finely chop the yellow onion. In a saucepan over medium heat, melt the unsalted butter and cook the onion for 6 to 8 minutes until soft but not coloured.
- Stir in the risotto rice and cook for 1 minute until the grains look glossy. Pour in the dry white wine and cook for 2 to 3 minutes, stirring, until it has almost evaporated.
- Add the tomato passata, fine sea salt and black pepper, then bring to a gentle simmer. Cook for 18 to 22 minutes, stirring often, until the rice is tender and the mixture is thick enough to hold its shape; if it looks dry before the rice is cooked, add a splash of water.
- Take off the heat and stir in the parmesan until melted and well combined. Spread the rice out in a mixing bowl and leave to cool completely, then chill until firm enough to shape.
- Cut the mozzarella into small cubes. Beat 2 eggs in a bowl; beat the remaining egg in a second bowl, and put the breadcrumbs in a third bowl.
- With damp hands, take a portion of the cold rice and flatten it in your palm. Place a cube of mozzarella in the centre, then wrap the rice around it and roll into a ball or short cylinder, pressing firmly so it is sealed.
- Dip each suppli first in the bowl with 2 beaten eggs, then coat in breadcrumbs. Repeat with the second egg and breadcrumbs for a thicker crust, pressing the crumbs on so they adhere well.
- Heat the vegetable oil in a large pot to 175°C (350°F). Fry the suppli in batches for 3 to 4 minutes, turning, until deep golden and crisp; keep the oil temperature steady between batches.
- Lift out with tongs and drain briefly, then serve hot so the mozzarella stretches when opened. Season lightly with a pinch more fine sea salt if you like.
Recipe notes
Tips
- Cool the rice fully before shaping; warm rice will split and leak cheese during frying.
- Keep the oil at 175°C (350°F) for an even crust; if it drops too low, the suppli will absorb oil and turn greasy.
- If serving anyone who is pregnant, elderly, or immunocompromised, use pasteurised egg and make sure the suppli are fried until piping hot throughout.
Substitutions
- Replace Dry White Wine with water for an alcohol-free version; add it gradually and keep simmering until the rice is tender and thick.
- Replace Parmesan with Grana Padano cheese for a slightly milder, sweeter finish.
- Replace Mozzarella with low-moisture mozzarella for a firmer centre and less leakage.
Storage
- Refrigerate up to 2 days
- Cool completely, then refrigerate in a sealed container. Reheat on a baking tray at 200°C (390°F) for 10 to 12 minutes until piping hot; freeze cooked suppli for up to 2 months and reheat from frozen at 200°C (390°F) for 18 to 22 minutes.
