Choosing the Right Onions

For this recipe, you will need four medium-sized onions. You can choose from red, yellow, or white onions, or even mix them up for a vibrant and colorful presentation. Keep in mind that different onion colors might roast at slightly different rates due to their varying water content.


  • 4 onion shells (yellow, red, or white), hollowed out for stuffing
  • 1 cup parsley, chopped roughly
  • 6 ounces ham, diced
  • 1 cup (approximate) vegetable or chicken stock
  • 4 tablespoons of sliced raw almonds

Grilling Tips for the Perfect Stuffed Onions

To ensure that your grilled stuffed onions turn out perfectly every time, keep these helpful tips in mind during the cooking process:

  1. Prevent flare-ups: If your grill is prone to flare-ups, place the stuffed onion atop a 2 or 3-inch square of onion skin. This will help protect the onion shell from getting scorched while grilling.
  2. Monitor the onion colors: Remember that different onion colors may roast at slightly different rates due to their varying water content. Be sure to keep an eye on them and adjust the cooking time as needed.
  3. Use indirect heat: Cooking the onions over indirect heat helps them cook more evenly and prevents the outer layers from burning.
  4. Rotate the onions occasionally: To ensure even cooking, rotate the onions on the grill periodically.
  5. Choose the right bread: Opt for good quality crusty bread, such as a French baguette, to make your stuffing. This will provide a better texture and flavor to the dish.
  6. Adjust the grill temperature: Maintain a consistent grill temperature of around 325-350°F during the final grilling stage. Adjust the flame as needed to maintain the desired temperature.
  7. Rest the onions: Allow the grilled stuffed onions to rest for a few minutes before serving. This will help the flavors meld together and make the dish even more delicious.

With these tips in mind, you’ll be well on your way to creating a mouth-watering and memorable grilled stuffed onions dish that your friends and family will love. So, fire up the grill and enjoy the delightful flavors of this unique and tasty recipe!
