Notes
Always shred your cheese from a block rather than using pre-shredded cheese, which contains anti-caking starches. You'll get better flavor and melt! Try a variety of cheeses in this recipe.
I've found that stirring the casserole after the initial 45 minutes helps redistribute the rice and cauliflower for even cooking before adding the final cheese topping.
Allow the baked casserole to sit for 5-10 minutes so that it can set properly, making it much easier to scoop and serve.
Avoid any lumps in the sauce by dissolving the cornstarch properly in the cold milk or cream before adding the other liquids.
Reduce clean-up and whisk the creamy broth sauce directly in the casserole dish instead of a separate mixing bowl!
You do not need to pre-cook the rice unless you are using brown rice or wild rice that takes longer to cook - in that case, pre-cook the rice and reduce or eliminate the water when mixing together the remaining ingredients.
