A delightful and easy-to-make casserole combining spinach, rice, and a blend of cheeses for a comforting meal.
Preheat your oven to 350°F (175°C).
Ensure the oven is fully preheated before baking for even cooking.
Grease a baking dish with butter or non-stick spray.
Use a dish with high sides to prevent overflow.
In a large mixing bowl, combine the cooked rice, spinach, Swiss cheese, Parmesan cheese, chopped onion, minced garlic, eggs, milk, cayenne pepper, black pepper, and salt. Mix thoroughly.
Mix gently to avoid breaking the rice grains.
Transfer the mixture into the prepared baking dish and spread evenly.
Press lightly to ensure an even surface.
Bake in the preheated oven for 25 minutes or until the mixture is set.
Avoid overbaking to keep the casserole moist.
Sprinkle mozzarella cheese on top and bake for an additional 5 minutes until melted and bubbly.
Broil for a minute for a golden crust.
Let the casserole cool for 5 minutes before serving.
Cooling helps the casserole set and makes serving easier.
