Air Fryer Arancini (Crispy Golden Risotto Balls with Melty Mozzarella)

Save

Arancini — golden, crisp balls of risotto with a molten mozzarella heart — are the kind of appetizer that disappears before the platter even makes it to the table. Traditionally deep-fried, these Sicilian bites are restaurant-menu royalty: shatteringly crisp on the outside, creamy and cheesy within, and endlessly dippable. The air fryer changes the equation completely. Hot circulating air turns a light breadcrumb coating deeply golden and crunchy with barely any oil, so you get all of the crackle and the cheese pull with none of the deep-fryer mess.

This version starts with a simple parmesan risotto, which gets scooped around cubes of fresh mozzarella, rolled in flour, egg, and seasoned breadcrumbs, then air-fried at 400°F until crisp and bronze. Each batch takes just 10–12 minutes in the basket, and the whole recipe makes about 16 arancini — enough to feed a crowd of eight as an appetizer, or a smaller group that keeps "just having one more."

They are tailor-made for New Year's Eve. They are make-ahead friendly (the risotto actually needs to chill, so the recipe rewards planning), they are one-handed finger food that does not need a plate, and they look impressive on a party spread next to champagne. The cheese-pull moment, when someone splits one open and the mozzarella stretches into long strands, does half the entertaining for you.

The recipe below walks through everything: cooking the risotto from scratch (or using leftovers), shaping and breading without the balls falling apart, air-fryer timing and batch strategy, and how to hold them warm when guests are running fashionably late.

Ingredients

For the risotto

• 1 tablespoon olive oil
• 1 small yellow onion, finely diced (about 1/2 cup / 75 g)
• 2 cloves garlic, minced
• 1 cup (200 g) arborio rice
• 3 1/2 cups (830 ml) warm low-sodium chicken or vegetable broth
• 1/2 cup (50 g) freshly grated parmesan cheese
• 2 tablespoons unsalted butter
• 1/2 teaspoon fine sea salt, plus more to taste
• 1/4 teaspoon freshly ground black pepper
• 2 tablespoons chopped fresh basil or flat-leaf parsley (optional)

For the filling and breading

• 6 oz (170 g) fresh mozzarella, cut into 1/2-inch cubes and patted dry (about 16 cubes)
• 1/2 cup (60 g) all-purpose flour
• 2 large eggs (about 100 g), beaten
• 1 1/2 cups (150 g) panko or Italian-seasoned breadcrumbs
• 1 teaspoon Italian seasoning
• 1/2 teaspoon garlic powder
• Olive oil spray

For serving

• 1 1/2 cups (360 g) warm marinara sauce
• Extra grated parmesan and fresh basil leaves, for garnish

Instructions

1. Make the risotto. Heat the olive oil in a large saucepan over medium heat. Add the diced onion and cook, stirring, until softened and translucent, 4–5 minutes. Stir in the garlic and cook 30 seconds more. Add the arborio rice and stir to coat every grain in oil, toasting for 1–2 minutes until the edges look translucent.
2. Add the broth gradually. Pour in about 1 cup of the warm broth and stir gently but often. When most of the liquid is absorbed, add another ladle or so. Continue adding broth and stirring until the rice is creamy and tender with a slight bite at the center, 18–22 minutes. You may not need every last drop of broth.
3. Finish and season. Remove the pan from the heat. Stir in the parmesan, butter, salt, pepper, and basil or parsley if using, until the butter melts and the risotto looks glossy and creamy. Taste and adjust the salt.
4. Chill the risotto. Spread the risotto in an even layer on a parchment-lined sheet pan and let it cool for 10 minutes at room temperature. Cover and refrigerate for at least 1 hour, or overnight. Cold, firm risotto is essential — warm risotto will not hold its shape.

5. Set up the breading station. Place the flour in a shallow bowl. Beat the eggs in a second shallow bowl. In a third bowl, stir together the breadcrumbs, Italian seasoning, and garlic powder.
6. Shape the arancini. Scoop about 3 tablespoons of the cold risotto and flatten it in your palm. Place a cube of mozzarella in the center, then cup your hand to enclose the cheese completely and roll into a smooth ball about 1 1/2 inches across. Repeat with the remaining risotto and mozzarella — you should get about 16 balls.
7. Bread the balls. Working one at a time, dredge each ball in flour and shake off the excess, dip it in the beaten egg, then roll it in the seasoned breadcrumbs, pressing gently so the coating adheres. Set the breaded balls on a tray and refrigerate for 20 minutes so the coating sets.
8. Preheat the air fryer. Preheat to 400°F (200°C) for 3 minutes. Lightly spray the basket with olive oil spray.
9. Air fry in batches. Arrange the arancini in a single layer in the basket with space between them — they need room for the hot air to circulate. Lightly spray the tops with olive oil spray. Air fry for 10–12 minutes, turning once halfway through, until deep golden brown and crisp. Repeat with the remaining balls. Serve immediately with warm marinara, garnished with extra parmesan and basil.

Variations

• Sun-dried tomato and basil: fold 1/3 cup chopped oil-packed sun-dried tomatoes and extra fresh basil into the finished risotto before chilling for a bolder, tangier ball.
• Mushroom and fontina: swap the mozzarella for cubes of fontina and fold 1 cup of finely chopped sautéed mushrooms into the risotto — an earthy, rich variation.
• Spicy arrabbiata: add 1/2 teaspoon red pepper flakes to the breadcrumb mixture and serve with spicy arrabbiata sauce instead of marinara.
• Mini cocktail size: roll 24 smaller balls (about 2 tablespoons of risotto each) and reduce the air-fry time to 8–10 minutes — ideal for a crowded New Year's Eve table.
• Gluten-free: use gluten-free panko and a gluten-free flour blend in the breading station; the risotto itself is naturally gluten-free.
• Oven-baked option: no air fryer? Bake on a parchment-lined sheet pan at 425°F (220°C) for 18–20 minutes, flipping once, until golden and crisp.

Storage

Arancini are at their best served hot, within minutes of leaving the air fryer. If you have leftovers, store them in an airtight container in the refrigerator for up to 3 days and re-crisp in the air fryer at 375°F (190°C) for 4–5 minutes — the microwave will soften the coating, so the air fryer is worth the few extra minutes. To make ahead, shape and bread the balls, cover tightly, and refrigerate for up to 24 hours; air fry straight from the fridge, adding 1–2 minutes to the cook time. Uncooked, breaded arancini also freeze well for up to 2 months — air fry from frozen at 375°F (190°C) for 14–16 minutes. Freezing cooked arancini is not recommended, since the coating loses its crunch when thawed.
