Rinse the grill. You need to clean the grill before you use it, especially if you want to place the onions directly on the griddle. Besides, using a clean grill will cook the food better.

To clean the grill, pour a little vegetable oil on a paper towel to wipe each connecting rod on the grill. Or you can pour oil directly onto the grate and use a spatula or other tools to remove scale and rust if necessary.
Some grills have a “clean” mode. If the above methods are not effective enough, you can use this mode of the grill (if available).

After cleaning, spray a little oil on the grill to prevent sticking. Oil not only helps clean the grill, but also prevents food from sticking to the grill. Make sure you do this step before turning on the oven, or the oil will dry out.

Any oil can be used. Since this oil is not for baking onions, you can use an inexpensive vegetable oil.

Decide whether to use foil, a baking tray, a baking tray, or a skewer. Using a utensil when grilling sliced onions is the easiest way to ensure that the onions cook evenly on all sides and don’t fall into the crevices of the grill. You can use foil, a baking tray, a baking tray, or a skewer.

Or you can simply place a piece of foil on the grill and poke holes to let out the heat.
If using skewers, soak them in water first to prevent them from catching fire.

{“smallUrl”:”https://www.wikihow.com/images_en/thumb/7/76/Grill-Onions-Step-4-Version-3.jpg/v4-728px-Grill-Onions-Step-4- Version-3.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/7/76/Grill-Onions-Step-4-Version-3.jpg/v4-728px-Grill- Onions-Step-4-Version-3.jpg”,”smallWidth”:460,”smallHeight”:259,”bigWidth”:728,”bigHeight”:410,”licensing”:”<div class=”mw-parser -output”></div>”}

If you don’t have the above tools, it’s best to roast large sliced onions or whole. However, it is easier to bake sliced onions in large circles because if you bake whole onions, it is inevitable that onions will cook unevenly.

Decide what ingredients to spread on the onions. Piu oil, salt, pepper, or a mix of your favorite seasonings can all be used to spread the grilled onion. Some people also like to use butter and beef broth. Whether you’re grilling sliced or whole onions, you can spread the following ingredients:

Honey mustard
Balsamic Vinegar
BBQ Sauce
Worcestershire sauce
Steak seasoning

Grilled Onions Sliced or Sliced Wedge Shapes

Buy a large onion, probably at the store. Vidalia onion is chosen by many people because of its size and taste. In addition, sweet onions are the most popular, and pilgrimages are also quite popular.

As long as the bulbs are big and fresh, any type of onion can be grilled. If baking whole, you should choose a balanced tuber so that the onion is cooked evenly.

Cut off the onion stalks and peel. Peel off the dry and soft outer skin. Observe if the inner layers of onions are wilted or damaged and peel off if necessary. Be careful not to peel too much to the end of the tuber.

Cut onions. To cut onions into slices, hold the tip of the root and place the onion on its side on a cutting board. Hands and root tips should be level with the cutting board. Cut the onion into slices about 1.5 cm thick.

To cut into wedge-shaped cubes, you should not cut the onion from top to bottom. Cut like this the wedge blocks will come apart. It is recommended to cut the onion into wedge blocks 2.5 cm wide and medium size (into 4-6 cubes). ^{[2] X Research Source}
The above two cuts are just suggestions. You can cut the onion into slices or cubes of any thickness you want. However, it should be noted that the smaller the onion slice, the easier it will be to fall into the slot of the grill. So if you cut onions, you need to use extra tools to prevent the onions from falling into the slot.

Spread the piu oil and seasoning on the onion slices. You can use whatever seasoning you like like salt, pepper or garlic powder. Or you can also use the seasonings suggested above, but piu oil, salt, and pepper are the most basic. Also, be careful to spread both sides of the onion slices.

Heat the grill to medium heat. Place the onion slices directly on the grill. You can also use a grill basket or foil tent if you want. Bake for 3-5 minutes or until black spots appear on the onion slices. Thick and large sliced onions need to bake for about 7 minutes. ^{[3] X Research Sources}

To make a tent from foil, you just need to put a few slices of onion on a piece of paper. Then fold the long edges of the paper in so that the onion slices are covered and then roll the edges tightly.
The skewers are the easiest wedge-shaped onion grills to keep the wedges from coming apart. You need to soak the skewers in water before using to avoid catching fire.

Grilled Raw Onions

Peel off the dry and soft outer skin. Observe if the inner layers of onions are wilted or damaged and peel off if necessary. Continue peeling until the onion layer is as standard as you want.

Keep the root end of the onion intact. The roots will support the onion.

Cut onions. Cut off the top 1/3 of the onion. Next, you need to cut off the core of the onion by inserting a knife into one corner of the core. Be careful not to pierce the knife all the way to the bottom (otherwise the onion will not be intact). Continue to run the knife around the core until the core can be removed while the bottom of the tuber is still intact.

From the core, use a knife to cut the outer layers of the onion but not the outermost layer. This step will help the seasoning to penetrate each layer of onions. ^{[4] X Research Sources}
Or you can use the tip of a knife and poke a small hole around the middle part of the onion. Instead of adding seasoning to the core, put it in these small holes.

{“smallUrl”:”https://www.wikihow.com/images_en/thumb/1/12/Grill-Onions-Step-15-Version-2.jpg/v4-728px-Grill-Onions-Step-15- Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/1/12/Grill-Onions-Step-15-Version-2.jpg/v4-728px-Grill- Onions-Step-15-Version-2.jpg”,”smallWidth”:460,”smallHeight”:259,”bigWidth”:728,”bigHeight”:410,”licensing”:”<div class=”mw-parser -output”></div>”}

Season to taste. Most people base the spread with butter or piu oil. Then you can add your favorite seasonings like salt, pepper, garlic powder or the suggestions above.

Combine herbs and spices or commercially available seasonings (such as steak seasoning) to bring out the natural flavor of the onion. Note that you should use sweet or savory seasoning depending on the dish you want to serve with grilled onions.

Use foil to cover the whole onion. Place the onions on the grill over medium to medium heat and bake for about 20-30 minutes. It should only be checked 1-2 times to avoid letting the heat escape.

Some onions (and the grill) require up to 45 minutes of baking. You don’t need to worry if onions need to bake longer than 20-30 minutes as that is normal for large onions. If you’re not sure if the onion is cooked through, you can bake it a little longer. Onions that are only slightly warm means they are not yet ripe.

Remove the onion from the grill and enjoy. Whole roasted onions are often considered a complete dish and you only need to add some mixed vegetables with a slice of fresh bread. However, if you want, you can use grilled onions to make stews, curries, or other vegetable dishes.

Advice

When preparing sliced onions, you should not cut off the tips of the roots. Leave the tips of the roots intact to keep the onions intact and easier to slice.
This article uses Vidalia onion or yellow onion as an example material. However, if you have mastered how to grill onions, you can try baking different types of onions. Each type will have a different taste and bring a different feel to the dish. The most common are yellow, white, red, and purple onions and you can find them in grocery stores.
If the grill surface has a large slit or a small onion slice easily slips through the slot, use the grill basket to roast the sliced onion. To make a baking basket, fold a piece of foil in half and then stand the edge of the paper upright to form the edge of the basket about 2.5cm high. Next, fold the 4 corners of the basket down and twist it tight. Place the sliced onions in the basket and place on the griddle.
The longer the onion is baked, the softer it will be. Therefore, you should try baking several times and decide how long the baking time will give the most satisfactory results.

Warning

When slicing onions, place them on a dry cutting board to avoid slipping. Also, you need to keep your fingers bent or pinched together and away from the blade when cutting.
