Suppli al Telefono (Roman Fried Rice Balls)

Supplì al telefono are Roman-style fried rice croquettes with a tomato-rich risotto base and a molten mozzarella centre. Unlike plain arancini, these are usually shaped as balls or short cylinders, crumbed generously and fried until the shell is crisp enough to crack open against the soft, savoury rice inside. Their defining feature is the cheese pull — the “telephone” effect — which is why they are best served straight from the fryer. They make excellent antipasti, snacks or lunch bites, with parmesan adding depth and passata giving the rice its recognisable red hue.

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.

  1. 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.
  2. 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.
  3. 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.
  4. 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.
  5. 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.
  6. 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.
  7. 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.
  8. 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.
  9. 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.
