I love this recipe that includes french onion fried rings! I am also kicking around the idea of placing several frozen onion rings on top. It might be really good!
2 lb. pkg. frozen hash brown potatoes (partially thawed)
2 (10-oz.) cans Cheddar cheese soup
13 oz. can evaporated milk, undiluted
3 oz. can French Fried Onion Rings
Salt and Pepper to taste
Combine partially frozen potatoes, soup, milk, and half the onion rings. Pour into well-greased Crockpot. Add salt and pepper to taste. Cover and cook on LOW for 7 to 9 hours or HIGH about 3 hours. Sprinkle remaining onion rings over top before serving
