The next time you want to switch up a regular rice dish, use brown rice instead of white. Brown rice tastes much nuttier than white rice, which can sometimes be quite bland. Plus, brown rice is also much chewier with just a touch more firmness that works well in casseroles, including in the recipe that follows. When cooking the rice, stock is used that also infuses flavor into this dish. Even though this recipe uses chicken stock, you can keep it completely vegetarian by choosing vegetable stock instead.
It wouldn't be much of a casserole, though, if it only used rice. You'll need some other ingredients to make it a little more substantial, and broccoli and corn are the ideal additions. This dish uses fresh broccoli, but frozen would work just as well. Fresh corn really is best, as you get that sweet corn milk that will make the flavor shine through even more. If you can't use fresh, opt for frozen instead of canned. Not only is it sweeter, it also won't turn to mush as the canned stuff usually does in casseroles.
