Recipe tips & variations
For an extra burst of flavor, consider adding some minced garlic to the sauce. You can also toss in some chopped vegetables like bell peppers or spinach for a nutritional boost. If you’re looking for a bit of spice, a pinch of red pepper flakes can do wonders.
Want to make it a bit more indulgent? Swap the marinara with a creamy Alfredo sauce or add more cheese on top.
Storage & reheating
This casserole stores beautifully. Simply pop any leftovers into an airtight container, and it will keep in the fridge for up to 3 days. To reheat, place in a microwave-safe dish and warm in the microwave or reheat in the oven at a low temperature until heated through.
FAQs
Can I use fresh meatballs instead of frozen?
Absolutely! If using fresh meatballs, make sure they are cooked through before adding them to the casserole.
What other types of rice can I use?
Long grain white rice works best, but you can try brown rice for a nuttier flavor, keeping in mind it might require a little more liquid and cooking time.
Is there a way to make this dish vegetarian?
Sure thing! Swap the meatballs with veggie meatballs available in stores, or use some roasted vegetables for a plant-based version.
