Ingredients

1 cup (200 g) Arborio rice
4 cups (960 ml) vegetable or chicken broth, kept warm
1/2 cup (120 ml) dry white wine
2 tbsp (30 ml) olive oil, divided
2 tbsp (28 g) unsalted butter
1 small onion, finely chopped (about 1/2 cup / 75 g)
2 cloves garlic, minced
8 oz (225 g) cremini or button mushrooms, finely chopped
1 tsp (5 ml) truffle oil, plus more for brushing (optional)
1/2 cup (50 g) grated Parmesan cheese
1 large egg, lightly beaten
1 cup (120 g) all-purpose flour
2 large eggs, beaten (for coating)
1 1/2 cups (150 g) panko breadcrumbs
Vegetable oil, for frying (about 2 cups / 500 ml)
Salt and freshly ground black pepper, to taste

Instructions

Make the risotto: In a large saucepan, heat 1 tablespoon of olive oil and the butter over medium heat. Add the onion and garlic, cooking until soft, about 3 minutes. Add the mushrooms and cook until they release their liquid and start to brown, about 5-7 minutes. Season with salt and pepper.
Add the rice and stir to coat with the oil, toasting for 1-2 minutes. Pour in the white wine and stir until it is mostly absorbed.
Begin adding the warm broth, one ladleful at a time, stirring frequently. Wait until each addition is mostly absorbed before adding the next. Continue until the rice is creamy and al dente, about 18-20 minutes. You may not need all the broth.
Remove from heat and stir in the Parmesan cheese and truffle oil (if using). Taste and adjust seasoning. Spread the risotto on a baking sheet to cool completely, about 30 minutes.
Form the arancini: Once the risotto is cool, use your hands to shape it into 1.5-inch (4 cm) balls, about 2 tablespoons each. You should get about 18-20 balls.
Set up a breading station: place the flour in one shallow bowl, the beaten eggs in another, and the panko breadcrumbs in a third.
Roll each rice ball in the flour, then dip in the egg, and finally coat thoroughly with panko breadcrumbs. Press gently to adhere. Place the breaded arancini on a plate and refrigerate for at least 30 minutes to firm up.
Fry the arancini: In a deep, heavy-bottomed pot, heat about 2 inches (5 cm) of vegetable oil to 350°F (175°C). Working in batches, carefully add the arancini without crowding. Fry until golden brown and heated through, about 3-4 minutes per batch, turning occasionally.
Drain on paper towels. If desired, brush lightly with a little truffle oil while hot. Serve immediately.

Tips

Chilling is key: Do not skip chilling the risotto before shaping, and the breaded balls before frying. This prevents them from falling apart in the oil.
Substitute mushrooms: If you can’t find cremini, use button mushrooms or a mix of wild mushrooms like shiitake or oyster. Dried porcini, rehydrated and chopped, also add intense flavor.
No truffle oil? You can omit it or add a tablespoon of truffle butter to the risotto instead. For a budget-friendly option, use a high-quality extra virgin olive oil with a few drops of truffle essence.
Common mistake: Overcrowding the pan drops the oil temperature, making the arancini greasy. Fry in small batches and allow the oil to return to temperature between batches.

Serving Suggestions

Serve truffle mushroom arancini as an elegant appetizer with a simple aioli or marinara sauce for dipping. They also pair beautifully with a fresh green salad dressed with lemon vinaigrette. For a heartier meal, serve them alongside a bowl of tomato soup or as a side to grilled meats.

Variations

Cheese-stuffed: Insert a small cube of mozzarella or provolone into the center of each rice ball before breading for a gooey, melty surprise.
Meat ragu: Add 1/2 cup (120 g) of cooked ground beef or Italian sausage to the risotto for a more substantial version.
Baked option: For a lighter take, brush the breaded arancini with olive oil and bake at 400°F (200°C) for 20-25 minutes, or until golden and heated through.
Add spinach: Stir in a handful of chopped fresh spinach to the risotto at the end for extra color and nutrients.

Storage and Reheating

Store leftover arancini in an airtight container in the refrigerator for up to 3 days. To reheat, place them on a baking sheet and warm in a 375°F (190°C) oven for 10-12 minutes, or until crisp and heated through. Avoid microwaving, as it makes them soggy. You can also freeze uncooked breaded arancini on a baking sheet until solid, then transfer to a freezer bag for up to 2 months. Fry from frozen, adding a couple of minutes to the cooking time.

Frequently Asked Questions

Can I use leftover risotto? Absolutely! This is a great way to use up leftover risotto. Just make sure it’s fully cooled and firm enough to shape. If it’s too sticky, you can add a little breadcrumb or flour to help bind it.

Why are my arancini falling apart? This usually happens if the risotto is too wet or not chilled enough. Be sure to cook the risotto until it’s thick and creamy, and chill it thoroughly before shaping. Also, handle the balls gently when breading and frying.

Can I make arancini ahead of time? Yes, you can prepare and bread the arancini up to a day in advance. Keep them covered in the refrigerator, then fry just before serving. This makes them perfect for parties.

What is the best oil for frying? Use a neutral oil with a high smoke point, such as vegetable, canola, or peanut oil. These oils won’t impart a strong flavor and can handle the high heat needed for a crispy exterior.

Can I make this gluten-free? Yes, simply substitute the all-purpose flour with a gluten-free flour blend and use gluten-free breadcrumbs. The rest of the ingredients are naturally gluten-free.

Is truffle oil necessary? No, truffle oil adds a distinct flavor, but you can omit it or use a truffle-infused salt or butter instead. The mushrooms and Parmesan already provide a deep umami flavor.
