arancini balls mushroom and spinach

Impress your picnic buddies or your littlest loves with these delicious oven-baked mushroom and spinach arancini balls.

While risotto balls could be considered a labour of love, you will be sure to charm and delight with these bite-sized morsels. Take these along to your next spring picnic and you certainly won't be bringing any home with you!

To make these arancini balls, you firstly have to make the risotto – you can either make them from scratch each time, or whip them up using leftover risotto. They're filled with a delicious mozzarella cheese and dipped and rolled in a crunchy panko breadcrumb.

Our oven-baked risotto balls are a little healthier than the deep-fried alternative, making them the ultimate snack or meal for kids.

Arancini Balls


  • mushroom and spinach risotto, cooked and chilled (see recipe above)
  • 2 eggs, beaten
  • 60 g (1/2 cup) all purpose flour
  • 100 g (1 1/2 cup) panko breadcrumbs

  2. Place in freezer for 10 minutes as this makes the balls easier to work with.

  3. Preheat oven to 180 C and line a baking tray with parchment paper.

  4. Place flour in a dish, beaten egg in another, and the breadcrumbs on a flat plate.

  5. Remove from freezer and using the end of a spoon, make a hole in the middle of each ball and place a cube of mozzarella inside, molding the risotto around it again.

Arancini balls can be frozen for 1-2 months. Prepare the recipe as directed but do not bake the balls. Instead, place the balls on the lined baking tray then place in the freezer. When the balls are frozen, transfer them to an airtight container or ziplock bag. When needed, allow the arancini balls to defrost completely then place them back on a baking sheet and bake as directed.
