Baked Italian rice balls, often called arancini, are made from seasoned rice shaped around a filling, coated in breadcrumbs, and cooked until golden. This oven-baked version has Parmesan rice and a molten mozzarella center, with a crisp shell that needs only a little oil. Sicilian arancini and other regional or family versions vary in shape and filling; this approachable recipe is designed for a home oven.
Ingredients
- 1½ cups (300 g) arborio rice
- 4 cups (960 ml) low-sodium chicken broth or vegetable broth, warmed
- 1 tablespoon (15 ml) olive oil, for cooking the onion
- ½ cup (75 g) finely chopped yellow onion
- 1 tablespoon (14 g) unsalted butter
- ½ teaspoon (3 g) fine salt, or less if the broth is salty
- ¼ teaspoon (0.5 g) freshly ground black pepper
- ½ cup (45 g) finely grated Parmesan cheese
- 1 large egg (about 50 g without the shell), lightly beaten
- 8 ounces (225 g) low-moisture mozzarella, cut into 8 roughly 1-inch (2.5 cm) cubes
- ½ cup (60 g) all-purpose flour
- 2 large eggs (about 100 g without the shells), beaten for coating
- 1½ cups (90 g) plain dried breadcrumbs or panko
- 2 tablespoons (30 ml) olive oil, for brushing or drizzling
Instructions
- Warm the broth. Pour the broth into a small saucepan and heat it over low heat until steaming but not boiling. Keeping it warm helps the rice cook evenly when you add it. Set out a rimmed tray or shallow container for cooling the rice later.
- Start the rice. Heat 1 tablespoon olive oil and the butter in a wide, heavy saucepan over medium heat. Add the onion and cook for 4 to 5 minutes, stirring, until softened but not browned. Stir in the rice and cook for about 1 minute so each grain is coated. Add the salt and pepper.
- Cook until tender. Add about ½ cup (120 ml) warm broth at a time, stirring often and letting most of the liquid absorb before adding more. Continue for about 18 to 20 minutes, using the broth as needed, until the rice is tender but still holds its shape. The mixture should be moist and cohesive, not soupy. Spread it promptly in a shallow layer on the tray. Refrigerate it for 1 hour to chill; do not leave cooked rice at room temperature for an extended period.
- Prepare the oven and coating station. Heat the oven to 425°F (220°C). Line a rimmed baking sheet with parchment paper and lightly brush or drizzle it with some of the measured oil. Put the flour in one shallow bowl, the 2 beaten coating eggs in a second bowl, and the breadcrumbs in a third.
- Season and portion the chilled rice. Transfer the cold rice to a mixing bowl. Stir in the Parmesan and the remaining lightly beaten egg until evenly distributed. Divide the mixture into 8 portions. If it sticks to your hands, dampen your palms lightly with water rather than adding extra flour, which can make the centers heavy.
- Fill and shape the balls. Take one rice portion and flatten it into a thick disk in your palm. Place a mozzarella cube in the middle, then bring the rice up around it and pinch the seam closed. Roll gently into a ball about 2½ inches (6 cm) wide. Check for thin spots or exposed cheese, then repeat with the remaining portions. A sealed center helps prevent cheese from leaking onto the pan.
- Bread each ball. Roll one ball in flour and tap off excess, dip it in the beaten eggs, then turn it in the breadcrumbs until fully covered. Set it on the prepared baking sheet and repeat. Arrange the balls with space between them, then brush or drizzle the remaining olive oil over the crumb coating so it browns in the oven.
- Bake until crisp and safely cooked. Bake for 20 to 25 minutes, turning the balls carefully halfway through, until the crumbs are golden and the centers are hot. Check the center of a ball with a food thermometer: because the mixture contains egg, USDA FSIS gives 160°F (71°C) as the safe minimum internal temperature for egg dishes. Let the balls stand for 3 minutes before serving; the filling will be very hot.
Tips
- Keep the rice firm and cool. Arborio rice gives the balls a pleasantly cohesive texture, but avoid cooking it until it turns to loose porridge. Spread it in a shallow layer and chill it before shaping; warm, wet rice is harder to seal around the cheese and more likely to split.
- Choose the right mozzarella. Low-moisture mozzarella melts into a stretchy center without adding much water. Fresh mozzarella can work, but drain it very well and pat it dry first; excess moisture can soften the rice and cause leaks.
- Use a substitute that suits the recipe. If arborio is unavailable, another short-grain risotto rice is the closest choice. In a pinch, use short-grain sushi rice, cooked until sticky; the flavor and bite will differ slightly. For a vegetarian batch, choose vegetable broth and check that the Parmesan is made with a vegetarian-friendly rennet if that matters to you.
- Seal gently, not loosely. Press the rice together around the mozzarella and smooth over cracks before breading. If a ball breaks while shaping, patch it with a small piece of rice mixture. Don’t pack the balls so tightly that they become dense.
Serving Suggestions
Serve the rice balls hot, while the mozzarella is still soft, with warm marinara in a small bowl for dipping. A simple green salad dressed with lemon and olive oil or a plate of roasted vegetables balances the rich, cheesy centers. For an antipasto-style spread, add olives, marinated artichokes, and sliced vegetables; keep the rice balls as the warm centerpiece rather than crowding them with other heavy dishes.
Two balls per person make a satisfying main-course portion for many appetites, while one per person works well as an appetizer alongside other snacks. If serving a group, bake in batches and bring the first tray to the table as soon as it has rested. The breading is crispest straight from the oven, so set out sauce and plates before the balls finish baking.
Variations
For a classic meatier direction, tuck a teaspoon of thick, fully cooked meat ragù into the center with the mozzarella. Keep the filling modest so the rice can close around it. A Sicilian-inspired version can include a few cooked peas with the filling; pat them dry and use only a small amount so they do not make the center wet. These are variations rather than requirements, since rice-ball fillings differ across regions and households.
For a meat-free variation with more color, use a small spoonful of sautéed mushrooms or finely chopped roasted red pepper alongside the mozzarella. Cook vegetables until their moisture has evaporated and cool them before filling. You can also replace Parmesan with a similar hard, finely grated cheese, understanding that the saltiness and flavor may change. Panko gives a lighter, craggier coating; standard fine breadcrumbs make a more even, compact crust.
To make smaller party bites, divide the rice into 16 portions and use small mozzarella pieces. Begin checking them at about 15 minutes because smaller balls brown and heat through faster; still check a center with a thermometer for 160°F (71°C). Avoid making the balls much larger than directed unless you allow extra baking time and verify the center temperature.
Storage and Reheating
For food safety, refrigerate cooked rice balls within 2 hours of baking. Store them in a covered container in the refrigerator for 3 to 4 days. Letting them cool briefly before covering helps limit trapped steam, but do not leave them out to cool for hours. The coating will soften in storage, though reheating in an oven or air fryer can restore some crispness.
Reheat refrigerated rice balls on a baking sheet in a 350°F (175°C) oven for about 12 to 18 minutes, turning once if needed, until hot throughout. Check the center of a ball with a food thermometer; USDA FSIS recommends reheating leftovers to 165°F (74°C). An air fryer also works: heat at 350°F (175°C) for roughly 8 to 12 minutes, checking early because appliances vary. Avoid relying on a microwave for the whole batch, as it tends to make the crumb coating soft; if using one for a quick portion, finish briefly in a hot oven or air fryer.
To freeze, arrange fully cooled, baked balls in a single layer until firm, then transfer them to a freezer-safe container for up to 2 months for best quality. Reheat from frozen in a 375°F (190°C) oven, allowing about 25 to 35 minutes and checking the center for 165°F (74°C). The crumb may be a little less crisp than when freshly baked. Do not leave cooked rice balls at room temperature for storage.
Frequently Asked Questions
Can I make baked Italian rice balls ahead?
Yes. Cook and chill the rice up to 1 day ahead, covered in the refrigerator, then mix in the Parmesan and egg, fill, bread, and bake when convenient. You can also shape and bread them several hours ahead; keep them covered and refrigerated, then bake cold, adding a few minutes if needed. Check the center temperature rather than judging only by browning.
Why are my rice balls falling apart?
The rice may be too warm, too wet, or insufficiently sealed around the filling. Chill the rice thoroughly, make sure it is cohesive rather than soupy, and press the seam closed before breading. A thin flour-egg-crumb coating also helps hold the surface together. If the mixture feels loose, chilling it a little longer is better than adding a large amount of flour.
Can I use leftover risotto?
Yes, provided it has been handled safely and is not too loose. Chill it promptly, then stir in the Parmesan and egg if they are not already included. Taste before adding salt, since leftover risotto may already be well seasoned. If it is very creamy, use slightly smaller portions and handle them gently so the filling stays enclosed.
Can I cook these in an air fryer instead?
Usually. Arrange the breaded balls in a single layer with room for air to circulate, lightly oil the crumbs, and cook at about 375°F (190°C), turning once, for roughly 12 to 16 minutes. Air fryers vary in size and intensity, so begin checking early and use a thermometer to confirm that the egg-containing center reaches 160°F (71°C). Cook in batches rather than stacking them.
Can I use fresh mozzarella or skip the egg?
Fresh mozzarella is possible if it is well drained and patted dry, but its extra moisture makes leaks more likely. The egg mixed into the rice helps bind the balls, while the other eggs help the breadcrumbs stick. Skipping the binder can make shaping less reliable; for an egg-free adaptation, use a suitable egg-free binder and coating method, and expect a different texture rather than assuming the same proportions will work.
