Onions are usually grilled at high heat – approximately 400 – 450 degrees Fahrenheit temperature – while caramelized onions are cooked on low heat for a longer time.
Restaurants usually call sautéed or caramelized onions grilled onions, which are often actually cooked on a griddle rather than a grill. If you want a restaurant style onions you are most likely looking for our caramelized onions.
What kind of onions should you use?
The best recommended onion for grilling is a sweet onion like Vidalias, which have a mellow sweeter flavor. And while we all know red onions are great for salads, they’re perfect for cooking on the grill as well.
How do you cut an onion for grilling?
The most important tip is to use a skewer in each slice of onion to keep the whole onion together while it grills. It also makes it easier to move them as needed, because we don’t want layers of the onion to fall apart when it starts to soften as it cooks.
First, you need to peel and cut the ends off a large onion. After that push the skewers through the onion crosswise at the same intervals.
You will need approximately 4 skewers for each onion. Both metal and wooden skewers will work well. If you use wooden skewers cut as much of the excess skewer off as possible on both sides of the onion after inserting it into the onion. This will help keep them from burning while onion is grilling.
Steps for Grilling Onions
- Preheat the grill for about 5 minutes.
- Brush onion slices with olive oil and season with salt and black pepper.
- Place each slice of onion on the grill.
- Cook for approximately 10-15 minutes on each side.
- Once the onion is tender it is done.
Tip: you don’t want to overcook the onion, so check it after 10 minutes. If it’s not ready, cook it a little longer, checking every few minutes.
