For a vegetarian option, substitute vegetable bouillon cubes for the beef bouillon. Add a pinch of your favorite herbs, such as thyme or rosemary, to the onion cores for an extra layer of flavor. If you don't have an outdoor grill, you can bake the foil-wrapped onions in a preheated oven at 375°F (190°C) for approximately the same amount of time. Be careful when opening the foil packets after grilling, as hot steam will escape.

Nov 7, 2024I accidentally punctured the foil on one of the onions, and it did burn a little. So, definitely be careful with the foil! But the ones that didn't leak were perfect.
