How to Store Onigiri Overnight (And Keep Them Delicious!)
Intro Made a big batch of onigiri to enjoy throughout the week? While these Japanese rice balls are ideally eaten fresh, there are ways to store them overnight while maintaining their deliciousness. In this guide, we'll cover everything you need to know about storing onigiri properly.
The Challenge of Storing Onigiri
Dry Rice: The primary issue with storing onigiri is the rice drying out in the refrigerator, losing its fluffy, tender texture.
Soggy Nori: The seaweed (nori) wrapping absorbs moisture from the rice, becoming soft and losing its satisfying crispness.
Best Methods for Storing Onigiri Overnight
Refrigeration:
Individual Wrapping: Wrap each onigiri tightly in plastic wrap to minimize moisture loss.
Airtight Container: Place the wrapped onigiri in an airtight container to further protect them.
Consume Soon: Refrigerated onigiri are best eaten within 24 hours for optimal flavor.
Freezing (For Longer Storage):
Filling Choice is Key: Freeze only onigiri with cooked fillings like grilled salmon, tuna mayo, or teriyaki chicken. Avoid raw fillings or those with delicate textures.
Double Wrapping: Wrap each onigiri tightly in plastic wrap, then place them in a freezer-safe bag or container. This double layer protects against freezer burn.
Thaw Properly: Transfer frozen onigiri to the refrigerator overnight to thaw before consuming.
Tips for the Best Results
Salt is Your Friend: Salting your hands and the rice while making onigiri helps preserve the rice's moisture and flavor.
Consider the Fillings: Pickled ingredients like umeboshi have natural preservative qualities, making those onigiri more resilient when stored.
Nori Strategy: For the best texture, store the nori separately and wrap the onigiri just before eating.
Reheating Gently: Warm leftover onigiri briefly in the microwave or toaster oven. A light brush of soy sauce before reheating can add back lost moisture and flavor.
Oiling for a Barrier: Try adding a very thin layer of sesame oil to the rice before shaping the onigiri. This can create a slight barrier and help keep the rice moist.
