Arancini Delicious Fillings: 6 Ideas That Work

Arancini are golden, crispy Italian rice balls, traditionally from Sicily, made from leftover risotto, stuffed with a savory filling, breaded, and fried until crunchy. The magic of arancini lies in the contrast between the crisp exterior and the molten, flavorful center. This guide covers six delicious, reliable fillings—from classic ragù to creative vegetarian options—so you can make restaurant-quality arancini at home.

Ingredients

  • 4 cups (800 g) cooked and cooled risotto (plain or lightly seasoned, see Tips)
  • 1 cup (100 g) all-purpose flour
  • 3 large eggs, beaten
  • 2 cups (200 g) dry breadcrumbs (panko or fine)
  • Vegetable oil for frying (about 4 cups / 1 L)
  • Salt to taste

For the Classic Ragù Filling (makes about 1½ cups / 375 g):

  • 1 tbsp (15 ml) olive oil
  • 1 small onion, finely chopped
  • 1 garlic clove, minced
  • 8 oz (225 g) ground beef (80/20)
  • 1/2 cup (120 ml) tomato passata or crushed tomatoes
  • 1/4 cup (30 g) frozen peas
  • Salt and black pepper to taste
  • 1/2 cup (50 g) grated Parmigiano-Reggiano

For the Mozzarella Filling:

  • 8 oz (225 g) fresh mozzarella, cut into 1/2-inch (1 cm) cubes, patted dry

For the Spinach and Ricotta Filling:

  • 1 cup (250 g) ricotta cheese
  • 1/2 cup (75 g) frozen chopped spinach, thawed and squeezed dry
  • 1/4 cup (25 g) grated Parmigiano-Reggiano
  • 1/4 tsp ground nutmeg
  • Salt and pepper to taste

For the Mushroom and Taleggio Filling:

  • 2 tbsp (30 ml) olive oil
  • 8 oz (225 g) cremini mushrooms, finely chopped
  • 1 shallot, minced
  • 1 tsp fresh thyme leaves
  • 4 oz (115 g) Taleggio or fontina cheese, cut into small cubes
  • Salt and pepper to taste

For the Pesto and Burrata Filling:

  • 1/2 cup (120 g) basil pesto (store-bought or homemade)
  • 4 oz (115 g) burrata, drained and torn into small pieces

For the Sausage and Provolone Filling:

  • 8 oz (225 g) sweet Italian sausage, casings removed
  • 1/2 cup (60 g) diced provolone cheese
  • 1/4 tsp fennel seeds, toasted and crushed

Instructions

  1. Prepare the risotto: If using leftover risotto, ensure it is cold and firm. If making fresh, cook a plain risotto with broth, butter, and Parmigiano, then spread it on a baking sheet to cool completely. It must be cold and stiff enough to hold its shape when rolled.
  2. Make the ragù (if using): Heat olive oil in a skillet over medium heat. Add onion and garlic, cook until soft, about 3 minutes. Add ground beef, breaking it up, and cook until browned, about 5 minutes. Stir in tomato passata and peas, reduce heat to low, and simmer for 10 minutes. Season with salt and pepper. Remove from heat and let cool completely. Once cool, stir in the Parmigiano.
  3. Prepare other fillings: For spinach-ricotta, combine all ingredients in a bowl. For mushroom-Taleggio, heat olive oil in a skillet, cook mushrooms and shallot until moisture evaporates, about 8 minutes, then season with thyme, salt, and pepper. Cool completely. For sausage-provolone, cook sausage in a skillet over medium heat, breaking it up, until no longer pink, about 6 minutes. Drain excess fat, cool, then mix with provolone and fennel seeds. For pesto-burrata, simply mix pesto and burrata in a bowl (do this just before assembling).
  4. Shape the arancini: Wet your hands with cold water to prevent sticking. Take about 1/3 cup (75 g) of cold risotto and flatten it into a disk in your palm. Place 1 to 2 teaspoons of filling (or a cube of mozzarella) in the center. Fold the risotto over the filling and shape into a ball, about 2 inches (5 cm) in diameter. Ensure the filling is completely enclosed. Repeat with remaining risotto and fillings.
  5. Set up the breading station: Place flour, beaten eggs, and breadcrumbs in three separate shallow bowls. Season the flour with a pinch of salt.
  6. Coat the arancini: Roll each rice ball in flour, shaking off excess. Dip in egg, allowing excess to drip off. Roll in breadcrumbs, pressing gently to adhere. For extra crunch, repeat the egg and breadcrumb steps (double-coating). Place coated arancini on a plate and refrigerate for at least 30 minutes (this helps them hold together during frying).
  7. Heat the oil: In a deep, heavy-bottomed pot, heat about 3 inches (7.5 cm) of vegetable oil to 350°F (175°C). Use a deep-fry thermometer to maintain the temperature.
  8. Fry the arancini: Working in batches of 4-5, carefully lower the arancini into the hot oil using a slotted spoon. Fry for 4-5 minutes, turning occasionally, until golden brown and heated through. The internal temperature should reach 165°F (74°C) for food safety, especially if using meat fillings. Remove with a slotted spoon and drain on paper towels. Season with salt immediately.
  9. Serve hot: Arancini are best enjoyed warm, when the cheese is still molten.

Tips

  • Use day-old risotto: Fresh risotto is too soft and will fall apart. Spread cooked risotto on a baking sheet and refrigerate uncovered for at least 2 hours, or overnight, to dry it out slightly.
  • Keep fillings thick and dry: Wet fillings (like too much tomato sauce) will soak through the rice and cause the arancini to burst. If your ragù is liquidy, simmer it longer to reduce. For mozzarella, pat it dry with paper towels before cubing.
  • Chill before frying: The 30-minute chill after breading is non-negotiable. It sets the coating and prevents the rice from falling apart in the oil.
  • Don’t overcrowd the pot: Frying too many at once drops the oil temperature, making the arancini greasy and pale. Keep oil at 350°F (175°C) and fry in small batches.

Serving Suggestions

Serve arancini as an appetizer with a simple marinara sauce for dipping, or alongside a crisp green salad with lemon vinaigrette. They also make a satisfying main course when paired with sautéed greens or a bowl of tomato soup. For a party, arrange them on a platter with toothpicks and a sprinkle of fresh parsley.

Variations

  • Vegetarian: Use the spinach-ricotta or mushroom-Taleggio fillings, and ensure the risotto is made with vegetable broth.
  • Spicy: Add red pepper flakes to the ragù or use hot Italian sausage in the sausage filling.
  • Baked version: Instead of frying, brush the breaded arancini with olive oil and bake at 400°F (200°C) for 20-25 minutes, turning once, until golden and heated through. They will be less crispy but still delicious.
  • Cheese-focused: For a simpler filling, use only a cube of mozzarella or provolone, omitting the ragù. This is a classic “al burroâ€� style.

Storage and Reheating

Cooked arancini can be refrigerated in an airtight container for up to 3 days. To reheat, place them on a baking sheet and warm in a 375°F (190°C) oven for 10-15 minutes, or until heated through and crispy. You can also freeze uncooked breaded arancini on a baking sheet, then transfer to a freezer bag for up to 2 months. Fry from frozen, adding 2-3 minutes to the cooking time. Do not refrigerate uncooked arancini for more than 24 hours before frying, as the rice can become mushy.

Frequently Asked Questions

Can I use regular rice instead of risotto rice? No, arancini require high-starch rice like Arborio, Carnaroli, or Vialone Nano. Regular long-grain rice won’t become creamy and sticky enough to hold together.

Why did my arancini fall apart during frying? Usually, the risotto was too moist or not cold enough. Make sure the risotto is very cold and stiff, and chill the breaded arancini for at least 30 minutes before frying.

Can I make arancini gluten-free? Yes, use gluten-free breadcrumbs and replace the all-purpose flour with a gluten-free flour blend or cornstarch. The rest of the recipe remains the same.

How do I know when the arancini are cooked through? The outside should be deep golden brown and crispy. To be safe, especially with meat fillings, insert an instant-read thermometer into the center—it should read 165°F (74°C).

Can I prepare arancini ahead of time for a party? Absolutely. Assemble and bread the arancini up to 24 hours in advance, keep them refrigerated, and fry just before serving. Or fry them fully, then reheat in the oven as described above.

What is the best oil for frying? Use a neutral oil with a high smoke point, such as vegetable, canola, or peanut oil. Olive oil has a lower smoke point and can burn.
