Ingredients Needed for this Recipe:

(*full recipe card, plus video on the below!)

  • Long grain rice: choose a stick rice for this recipe.
  • Eggs
  • Butter
  • Cheese
  • Ground beef: choose a package the leanest chopped meat you can find.
  • Vegetables: you will need frozen peas, garlic and onion.
  • Tomato Sauce: we prefer our Mom’s Quick Marinara Sauce. It is quick and fresh tasting and requires only 4 ingredients.
  • Seasonings: you will need some salt and black pepper.
  • Cheeses: choose some grated pecorino cheese and Parmigiano-Reggiano cheese, plus shredded Mozzarella.
  • Bread Crumbs: choose plain bread crumbs or gluten-free.

Note and Tips for Success…

  • For our recipe, we used our Mom’s Marinara Sauce, which I had on hand.  But you can use your favorite store-bought sauce.  You will need a lot of prepared tomato sauce, about 4 cups, and more.
  • You will need “sticky rice” to make this casserole.  NOTE: Instant rice will not work! Best to use Long Grain Rice. 
  • Our mom always made this dish into a casserole with all the same fantastic ingredients of making “arancini” Sicilian popular rice balls. Only she preferred to make it with her Classic Bolognese Sauce and just added frozen peas to it.
  • This casserole is “baked” which makes a delicious dinner and clean-up a breeze!

Directions to make this casserole:

(*Follow along with our Step-by-Step directions, or jump down to the bottom for our full recipe card.)

1.  First, cook 3 cups of rice with 6 cups of water, and follow the directions on the package, including adding some butter (2 tablespoons) and 1 teaspoon of salt to the water.  When rice is cooked, transfer it to a large mixing bowl, add the additional butter, mix, and set aside to cool.

2.  In the meantime, using a medium skillet, sauté chopped onion and garlic in olive oil for 2 minutes.  Add the ground beef and cook the meat until browned and well cooked.  Using a wooden spoon, break the chopped meat while cooking.  Season with salt and pepper.  Add peas and 8-ounce (1 cup) of tomato sauce (prepared marinara sauce).  Simmer on low heat, covered for 5 minutes. Turn off the heat.

Next, in a large mixing bowl, combine rice with eggs, Pecorino cheese, and pour in 1 cup (8-ounces)  of marinara sauce, and mix well.  Rice will be sticky.

4.  Spray one 13 x 9 casserole dish, including all four sides, with cooking spray.  Add breadcrumbs to the baking dish, and roll the dish until the bottom and all sides are coated with breadcrumbs.

Frequent Questions & Answers…

  3. How to thaw, if Frozen? You will need to thaw completely on your counter, or overnight in the refrigerator. Also, allow the casserole to warm up to room temperature before baking, for at least 1 to 2 hours. This will ensure it will reheat evenly.
  4. How to serve this rice ball casserole? When serving, it’s best to have “extra” tomato sauce (heated) at the table when serving for those who prefer to add extra tomato sauce on top.
  5. Can we make this rice ball casserole healthier? You can also make this a little healthier and less fattening, you can use ground veal, chicken, or turkey, but my husband says “it’s not Sicilian if you don’t use beef! “..Lol… Either way, this is a dish everyone should try!

    1. Hi Kate,
      The butter in this recipe is mixed into the rice to keep the rice moist. I hope this helps!

  1. I plan to make this, but I have a question. I know you say to have plenty of sauce on hand, but how much total? The recipe calls for 24 oz., but I see 4 additions of sauce in the recipe, three 1-cup additions plus the last one says add remaining sauce, so that would be 8 oz x 3 = 24 oz plus the remaining ? oz. I don’t want to start if I need more than 24 oz, so I will wait til I make or buy more. Thank you so much; I can’t wait to make this!

    1. Hi Ann Marie,
      Welcome to our blog! It’s so nice to meet you! Yes, 24-ounces of sauce will be enough. (I had to read the recipe just to see if I missed something)
      Also, if you have extra tomato sauce, you can add an additional spoonful on top of each piece when serving, that’s the way I prefer it – but that’s just me! – I love it when it’s smothered in tomato sauce. 🙂 … So you can go ahead and make it! ENJOY!!

    2. I noticed that as well, but then I reread and the rice mixture calls for 8oz of “tomato sauce” versus marinara sauce so I was wondering if the ingredients are missing the 8oz can of tomato sauce or if it actually is supposed to be 32oz of marinara plus extra for topping.

      1. Hey Kerri! Thanks for bringing that up. I will go in and edit that! It is the “marinara sauce” that is mixed in with the rice.

      2. Hi Kerri,
        Thanks again! I went in and edited the recipe, it should be 28oz of prepared marinara sauce, plus extra for serving.

  2. This looks so good. I am making it tomorrow! Gluten free here and haven’t had a rice ball in a long time. Can’t wait!

    1. Thank you, Maria, and welcome to our blog! It’s so nice to meet you! Enjoy this recipe- it’s one of our favorites! 🙂

  3. Have a family member with severe egg allergies, what could I substitute the eggs with to make this dish? Thank you!

    1. Hello Hongchao!
      Great question! I have never made this casserole without the eggs, so I called my Aunt Tina ( my dad’s sister who is 96 and still makes her famous rice balls…. and she recommends to add 1/2 cup of grated Parmesan cheese and 2 to 3 additional tablespoons of butter to the rice mixture. The eggs is to bind the rice mixture a little, and to keep them moist while bakiing. So the butter will make this casserole a little more creamer with the additional butter added.

      OR, Option #2 : and this is my guess. Add an additional cup of tomato sauce to the rice mixture, and 1/2 cup of grated Parmesan cheese ( you already added percorino) to the rice mixture. That will keep the rice moist while baking. I hope this helps! 🙂
      Please come back and let me know if any these options have worked for you, because it will help others who read these comments and who may have the same allegy to eggs. Thanks so much!

      1. Thank you so much! I will update you how it turns out after I make it. Need to go get some parmesan cheese 🙂

        1. Hi Pam, I am not too sure about changing this casserole without changing the texture and flavor. But if I had to make a guess, maybe you can replace the rice with “cauliflower rice” and bind it with the eggs, butter, and cheese as it is in the recipe. If you make our casserole with the cauliflower rice, please come back and tell us the outcome. It will help so many who follow the keto diet. Thanks so much! Good luck 🙂

  4. This is a great idea for any leftover rice. Love it. I even have some leftover ricotta mixture from making involtini that would be a nice extra layer? Great and comforting. Happy New Year!

    1. Thank you Mimi!! That’s sounds delicious! Same to you, have a Happy and Healthy New Year!!

    1. Hello Silvana, I think you can freeze it before you bake it, (and freeze only up to 2 weeks). Then put it into the fridge overnight to defrost. Let is sit on the counter for at least one to 2 hours before baking it. Keep in mind, it may need more baking time as well. Then I would serve it with some additional tomato sauce at the table to add on top of each serving. Usually rice absorbs most of the sauce and it may get dry after you freeze it (it’s just a guess). I have never frozen this dish, so I am just guessing here. Please let us know how it turns out for you! Thanks for stopping by!

  5. Anna and Liz, is it ok to use instant rice? If so, it calls for 3 cups rice and 3 cups water. It is the Minute brand premium long grain instant rice. OR, is the long cooking long grain tastier?

    1. Hi Karen, I hope this is not too late. I have never used instant rice for anything and really can’t say how it will work with this recipe. We prefer only to use the long grain rice. But if you want to test it to see if instant rice will work, try using 1/4 of the ingredients and make a very very small casserole. I hope this will helps.

  6. Do you mind if I quote a few of your articles as long
    as I provide credit and sources back to your webpage? My
    website is in the very same niche as yours and my users would really benefit from some of
    the information you provide here. Please let me know if
    this alright with you. Thank you!

  7. This looks delicious! Might add some chopped red bell pepper with the onion, but this recipe sounds like pure comfort food! I love a dinner where I can clean up while it cooks!😊

    1. We are so glad you like this recipe !! It is a satisfying meal – perfect crowd pleaser too!
      Enjoy and thank you for taking the time to write a comment!
