Common Mistakes to Avoid
Grilling onions can be tricky if you’re not careful. Here are some common mistakes to avoid for the Best Ever Grilled Onions.
- Not using the right onions – Sweet onions like Walla Walla or Vidalia are best for grilling because they caramelize beautifully. Choose these varieties for optimal flavor.
- Skipping the skewer – Failing to skewer your onions can lead to uneven cooking. Skewering keeps the slices together and makes flipping them easier on the grill.
- Overcooking or undercooking – Cooking too long can burn the onions while not cooking long enough can leave them crunchy. Aim for a nice golden color and tenderness.
- Neglecting seasoning – A little salt and pepper go a long way in enhancing flavor. Always season your onions after oiling them, so they absorb the taste.
