White Broccoli Rice Casserole

1 ½-2 cups leftover fresh broccoli steamed with garlic and olive oil. Include steamed garlic pieces if you have any. Chop if necessary.
1 can cream of chicken soup
½ cup sour cream
½ cup uncooked rice with 1 cup water for cooking (I used Jasmine)
1 ½ cups Italian blend shredded cheese, divided
¼ tsp white pepper
1 Tbsp dehydrated chopped onion
¼ tsp salt

Cook rice. Combine rice in mixing bowl with all ingredients, reserving ½ cup of cheese for top of casserole. Put in 2-quart casserole dish coated with cooking spray and sprinkle reserved cheese on top. Bake in 375 degree oven for 20-30 minutes, or until warmed through and cheese is melted.
