These onions are delicious and can be served with roast chicken or ?? You decide. You can cut them in an "X" on the stem end, about 1/2 inch deep, before roasting if you want them to caramelize. Try using different types of onions, but similarly sized so that they all cook through at the same time. These will hold in a 200F oven for 45 minutes before serving. Use leftovers in pasta, salads or with sausage and eggs the next morning. From At Home With Michael Chiarello, one of my top three favorite chefs.
