Ingredients:
8 medium-sized Vidalia onions
1-2 T olive oil, for brushing onions
1 tsp. finely minced fresh rosemary (or use 1/2 tsp. dried rosemary, finely chopped with large knife)
2 T minced fresh thyme leaves (or use 1 T dried thyme)
Gratin Topping Ingredients:
6 T mayo (I used 4 T light mayo and 2 T full-fat mayo)
1 T fresh squeezed lemon juice
1/2 tsp. Dijon mustard
1 cup lowfat pizza cheese (any mild white cheese will work, but use low-fat cheese for the South Beach diet)
3 T grated Pecorino-Romano cheese (or use grated parmesan)
fresh ground black pepper to taste
Instructions:
Preheat oven to 450F/230C. Peel onions and cut in 1/2 inch slices. Spray or brush baking sheet with olive oil, then arrange onion slices in a single layer. Spray or brush onions with oil, then sprinkle with chopped herbs. Roast onions 15 minutes, then take them out and turn oven down to 375F/190C.
While onions roast, combine mayo, lemon juice, Dijon mustard, pizza cheese, Pecorino-Romano cheese, and black pepper in a small bowl. Mix together with a fork. (The mixture will be lumpy.)
Spray a 9″ x 13″ casserole dish with olive oil or nonstick spray. Remove baking sheet from the oven and use a turner to layer onions in the casserole dish. Spread topping over onions (I used a rubber scraper to spread it around. Don’t worry if the mixture doesn’t cover every bit of the onions.) Place casserole dish in oven and bake 25-35 minutes, or until top is golden brown and onions are slightly bubbling. Serve hot.
