They will take 8 to 10 minutes to cook on the grill, so you may plate them and put them on your burger bar before the patties are done. Make careful to cut the onion rounds into rings that are 1/2 inch thick.

The onion can withstand greater heat on the grill thanks to the thick slices. Onions should be grilled on skewers, and the onion slices should be held together by the skewers. Nothing is worse than having to chase a veggie down the grill grates or, even worse, across them.

Round or flat skewers are both acceptable. Since their extended design prevents whatever is on the skewer from turning, I like flat. Use two if you only have circular skewers.

Sweet onions, especially Vidalia, are excellent for grilling. They are substantial and get sweeter when grilled.
Yellow onions are another good option that is widely available. Although I like raw red onions, grilled red onions are nonetheless changed by the grill’s heat into a sweeter, less astringent version of themselves.

Two circular skewers inserted into an onion slice and spaced apart by a few inches hold the onion completely flat, allowing for simple flipping on the grill grate.

Many advise soaking wooden skewers, but I don’t mind if they burn just a little. The onion will not budge, but the skewer within the will, which holds the onion together. Nothing to worry about if the ends burn off.

Sprinkle some ground cayenne or ancho chili powder on the onions for added spice. Move the onions to an area of indirect heat if the grill is too hot, so they may continue to cook away from blazing coals.

Remove any onion portions that have become black. The leftover onion will be sweet and offer some texture to your burger in place of those bitter chunks. I promise that more time grilling your onions will improve your burger.


  • Two middle-sized sweet onions
  • Olive oil extra virgin, two tablespoons
  • Spread one tablespoon of kosher salt over the onions.


  1. Preheat. Set the grill to 400°F for preheating.
  2. Get your onions ready. After slicing off the root end, your onions should have the skin removed from the outside. Keep the onion rings intact while you cut the onion into 1/2-inch-thick slices. Each onion’s end slice should be thrown away.
  3. The onions on skewers. Insert a metal skewer very slowly through the center of the onion slices. This is simpler if you use the palm of your hand to press the onions firmly against the board and slide the skewers into the onions parallel to the board. Continue until all the onions are skewered.
  4. Onion seasoning On a baking sheet with a rim, spread out the onions. Combine the marinade ingredients in a medium bowl. As you turn the skewers to coat the onions on both sides, pour the marinade over the thinly sliced onions.
  5. Onions are grilled. On the grates of the heated grill, arrange the onions. Grill each side for 4-5 minutes. While grilling, baste the onions with the leftover marinade.

Remove the onions from the grill and serve them warm once cooked to your preference. The onions should be grilled outside while maintaining their structure and form.
  6. Serve right away. Serve them alone, on a burger, or on top of a steak for a flavor punch of sweetness and savoriness.

Whether grilled or caramelized, onions deliver a powerful yet palatable flavor punch. But I never fully understood the distinction between grilled and caramelized onions until a few months ago.

In fact, as a child, I had to swear off raw onions completely (for the most part!) after experiencing them on a Chicago hot dog one too many times. Why do I have trouble processing them? I won’t go into much detail, Restaurants served cooked onions, and they tasted…different. Over time, their sweetness increased while their saltiness decreased. As a result, they were physically superior. They were brighter in color.

It was said that they had been “caramelized.” I initially mistook a caramelized onion for an onion that had been charred. That is the sweetness and gloom, I reasoned. Wrong! Embarrassingly inaccurate, I made numerous attempts, but I was never successful. They just tasted scorched, not sweet, because I burned them.

What do Grilled Onions Taste Like?

The fact that grilling onions nearly completely transforms them into a different vegetable is another thing I appreciate about it. While raw onions can taste acrid, harsh, and sharp, cooked onions become sweet and flavorful as they caramelize. Believe me when I say that all the natural sugars come out and become sweet.

Which Onion is the Best for Grilling?

Our first preference while grilling is red onions. They cook up nicely when cut into wedges, and their interior texture becomes jammy rather than mushy, as white and yellow onions typically do. White onions are the mildest of all and are frequently the most popular.

Before grilling the sliced onions, soak them in cold water for an hour to further reduce the strong “onion” flavor. Yellow onions: You wouldn’t typically want to eat them raw because they have the strongest onion flavor. The flavor is the primary distinction between yellow and white onions.

White onions have a more powerful flavor that doesn’t work well in many meals. In contrast, yellow onions have a balanced aromatic and sweet flavor, making them an all-purpose onion. Make sure your knife is sharp before cutting an onion in half lengthwise for skewers. Each onion half should have the skin removed before being placed on a cutting board with the cut sides downward. To make four wedges, cut each half in half, then each quarter piece in half once more.

Cooking sliced onions over a charcoal barbecue. Onions are a good source of vitamin C and contain beneficial phytochemicals that aid your body in preventing blood sugar spikes and inflammation.

Do You Use Oil Or Butter to Sauté Onions?

Any fat that is suited for high-heat cooking may be used. My preferred oils for this are olive oil or vegetable oil. Additionally, butter can be used to enhance the flavor of the onions. Use a combination of butter and oil since butter has a lower smoke point than oil to prevent the food from browning too soon.

In a big skillet or pan, heat the butter or oil until it is hot. Use one tablespoon of lard per small to medium onion (you can use just about any fat). Use a nonstick pan and a tiny amount of water or vegetable broth to prevent sticking while sautéing onions in the absence of oil. Over medium-high heat, warm the oil in a pan or skillet with a broad bottom. When the appropriate level of softness and color is obtained, add the chopped or sliced onion aonionmmer, stirring regularly.

If necessary, turn down the heat to avoid burning. After two hours, refrigerate any leftovers. Even though they can be slightly softened in a tiny amount of liquid, onions are usually always cooked in some fat. Typically, this fat is a neutral oil like grapeseed, but it can also be bacon fat or butter.


Any onion can be cooked over a grill to your liking, but the Vidalia onion, which is big and sweet, is my particular favorite. These taste fantastic when grilled and maintain their sweetness and crispness while receiving additional caramelization. Any sweet onion will do if a Vidalia onion is unavailable. If you want to serve these to your family, the sweet onions are the most kid-friendly.

You can also grill red, white, or yellow onions, but remember that they will all taste somewhat different after being grilled. For this dish, sweet onion is unionist, but feel free to experiment with other onions! On the grill, you can discover that you prefer one onion kind over another.
