Baked supplì, crisp outside and stringy inside
Baked Roman supplì with tomato rice and a mozzarella heart: a golden crunchy crust and a filling that stretches, with no deep frying at all.

Are you after supplì as good as the ones from a Roman fry shop, without filling your kitchen with hot oil?
Then this baked version is for you. I will walk you through supplì with a golden crunchy coating and a mozzarella heart that genuinely stretches, cooked on a tray instead of in a pan.
The secret is not in the baking but in what comes before: tomato rice cooked on the dry side, finished with egg and parmesan and then cooled completely. Cold is what firms up the starch and lets you shape ovals that hold together instead of splitting.
There are at least three good reasons to make them this way: they can be prepared ahead, they freeze raw and coated, and they are far lighter than the fried version while still coming out crisp.
The detail that changes everything is oil on the coating. An oven alone will not brown breadcrumbs: you need a light film of oil applied by hand or with a spray, otherwise the crust stays pale and floury. And drain the mozzarella properly, because its water is exactly what makes supplì burst open.
Serve them just warm, when the filling still stretches but no longer scalds, with a small bowl of tomato sauce alongside. Cold they lose the telephone effect, but five minutes back in the oven brings it straight back.

Oven tray or baking dish
Perfect for baking meatballs and vegetables. Choose a non-stick tray for better results and easy cleaning.
Steps
- Heat the oil in a pan, pour in the tomato sauce and let it cook for 5 minutes with the basil, then add the rice and toast it for a minute, stirring.
- Cook the rice like a risotto, adding hot broth a little at a time, until it is done and fairly dry: rice that is too wet makes shaping impossible.
- Take it off the heat, stir in the parmesan and one whole egg, season with salt and pepper, then spread the rice on a wide tray and let it cool completely, ideally an hour in the fridge.
- Cut the mozzarella into sticks and let them drain on kitchen paper: the water in the mozzarella is the main reason supplì burst open while baking.
- Take a spoonful of cold rice in your palm, place a mozzarella stick in the middle and close it into a tight oval with no cracks.
- Roll each supplì in the remaining beaten egg and then in the breadcrumbs, pressing firmly so the coating sticks. For a thicker crust, repeat both steps.
- Arrange the supplì on a lined baking tray, drizzle them with oil and bake at 200°C (400°F) in a conventional oven for 20 minutes, turning them halfway, until golden and crisp. Serve hot, while the mozzarella still stretches.
Helpful tips
The rice must be cold and firm: make it the day before and shaping becomes far easier.
Drain the mozzarella well and use the drier pizza kind rather than the one packed in water.
A drizzle of oil on the coating is essential: without it the breadcrumbs stay pale and floury instead of turning golden.
You can freeze them raw and coated, then bake straight from frozen at 200°C for 30 minutes.
