Place the onions, cut-side up, in a greased baking dish. Drizzle with the oil and sprinkle with salt and pepper. Cover with aluminum foil and bake for 1 hours. Uncover and bake for a further 15 minutes or until just starting to brown.
Oven Baked Onion Rings - No need to deal with hot oil - these onion rings are easily baked to crisp-perfection right in the oven! *Not precisely healthy, but I wonder if there's a healthier breading choice, as these sound tasty and I LOVE onions*
Grilled Blue Cheese & Bacon Stuffed Onions - Serve with steak. Made cooked on grill during a hot day for 30 minutes. Were cooked almost perfect. I wouldn't eat them again but Mike would. Too blue cheesy for me. I would have added more bacon.
