Ingredients

1½ cups Minute instant white rice

1 (24 oz) jar pasta sauce

1 (14.5 oz) can Italian seasoned diced tomatoes (undrained)

1 cup water

30 frozen meatballs

1+ cups shredded mozzarella cheese

¼ cup grated Parmesan

Garlic powder, to taste

Instructions

  3. Spread the mixture evenly in the prepared dish.
  4. Arrange the frozen meatballs on top—no need to thaw.

Notes

  • Use instant brown rice for a whole grain option; increase bake time by 10–15 minutes.
  • Substitute plant-based or cooked fresh meatballs as desired.
  • Mix in frozen veggies for extra nutrition and color.
  • Customize with different cheeses like cheddar or pepper jack.
  • For a spicy twist, add red pepper flakes or chili powder.
  • Store leftovers in the fridge for up to 4 days or freeze before baking for up to 3 months.
  • To reheat, use microwave or oven until hot and bubbly.
