Step 1: Caramelize the Onions

Bring the mixture to a simmer, then reduce the heat to low and cover. Cook for 15–20 minutes , or until the rice is tender and most of the liquid is absorbed.
Step 4: Add the Cheese

Sprinkle the shredded mozzarella and Parmesan cheese evenly over the top of the casserole.
