Notes
There are three tricks to making sure your dump-and-bake rice casserole cooks properly.
Use my rice-to-water ratio - I've tested this numerous times to make sure it works.
Use boiling hot liquid - it must be hot for the rice to cook in this amount of time.
You need to foil or lid the casserole dish to trap the heat and steam so that the rice will cook in the oven.
StorageIf you have leftovers, let the crab sushi bake cool completely before storing it. Transfer it to an airtight container and refrigerate for up to 4 days.Store the extra sauce and toppings separately.I reheat leftovers in the microwave on the reheat function. You can also do this in 30 second intervals, stirring if necessary, until heat through.
