How To Cut Onions For Grilling

Grilling season is here, and what better way to elevate your dishes than by adding grilled onions? The delicious caramelized flavor of grilled onions can take your burgers, steaks, and even vegetarian meals to a whole new level. But before you fire up the grill, it’s important to know how to properly cut onions for grilling. Follow these steps to ensure you get the perfect cut every time.

Step 1: Choose the Right Onion

Before you start slicing, make sure you choose the right onion for grilling. While any onion can be grilled, sweet onions like Vidalia, Walla Walla, or Maui onions are particularly great options. They have a milder flavor and higher sugar content, which gives them a natural sweetness when grilled. However, if you prefer a stronger onion flavor, you can also opt for yellow or red onions.

Step 2: Prep the Onion

Start by peeling off the papery skin of the onion and removing the root end. Keep the stem intact, as it will help hold the layers together while grilling. Then, cut the onion in half from top to bottom, creating two equal halves.

Step 3: Slice or Dice

Slicing: If you prefer thinly sliced grilled onions to top your burgers or hot dogs, lay each onion half flat side down on the cutting board. Starting from the stem end, carefully slice the onion widthwise into thin, even slices. For even grilling, aim for slices that are about 1/4 inch thick.

Dicing: For recipes that call for diced grilled onions, start by cutting each onion half lengthwise, making sure to leave the stem end intact. Then, make horizontal cuts across the onion, again being careful not to cut through the stem. Finally, make vertical cuts to cross-dice the onion, creating small, evenly-sized pieces.

Step 4: Leave the Layers Intact

One of the key tips for grilling onions is to keep the layers intact as much as possible. This helps the onion maintain its shape while cooking and prevents it from falling apart or sticking to the grill. If you’re slicing the onions, separate the layers gently without breaking them. If you’re dicing, be careful not to cut through the stem, as it holds the layers together.

Step 5: Season and Grill

Now that your onions are cut, it’s time to season and grill them to perfection. Place the onions in a bowl and drizzle them with olive oil, then sprinkle with your favorite seasonings. Common choices include salt, pepper, garlic powder, or even a sprinkle of balsamic vinegar for added flavor.

Preheat your grill to medium-high heat and lightly oil the grates to prevent sticking. Carefully place the onions on the hot grill, keeping the layers intact as much as possible. Grill for about 5-7 minutes per side, or until the onions are tender and have a nice char on the edges.

For sliced onions, flip them using a spatula or grill tongs halfway through the cooking time.
For diced onions, use a grill basket or wrap them in a foil packet to prevent them from falling through the grates.

Once the onions are grilled to your desired level of caramelization, remove them from the heat and let them cool slightly before serving. Grilled onions can be enjoyed as a topping for burgers, steaks, sausages, sandwiches, or even as a tasty side dish.

Conclusion

Mastering the art of cutting onions for grilling is a game-changer for any outdoor cooking enthusiast. Whether you prefer thinly sliced or diced onions, following these steps will ensure that your grilled onions are flavorful, tender, and perfectly cooked every time. So, fire up the grill, grab your onions, and get ready to take your grilling adventures to a whole new level!

FAQ:

What type of onion is best for grilling?

When it comes to grilling onions, it’s best to use sweet onions such as Vidalia, Walla Walla, or Maui onions. These varieties have a milder and sweeter flavor that pairs well with grilled dishes.

Should I peel the onion before grilling?

Yes, it is recommended to peel the onion before grilling. Removing the outer skin helps to get rid of any dirt or debris and allows for an even cooking process. However, you can leave a thin layer of the papery skin intact to help hold the onion together.

How should I shape the onion for grilling?

To ensure the onion stays intact while grilling, it’s best to cut it into thick slices or wedges. This shape allows the onion to have more surface area for caramelization while still maintaining its structure. Aim for slices or wedges that are about 1/2 to 3/4 inch thick.

What is the best way to cut an onion for grilling?

Start by cutting off the top and bottom of the onion. Stand it upright on one of the flat ends and slice it in half from top to bottom. Next, peel off the outer skin and any dry or damaged layers. Finally, cut the onion into desired slices or wedges, ensuring they are of uniform thickness for even grilling.

Should I soak the onion before grilling?

Soaking the onion slices or wedges in cold water for about 10-15 minutes before grilling can help reduce the pungency and mellow out the flavor. Additionally, this can make the onion slightly more tender and prevent excessive charring during grilling.

Can I season the onion before grilling?

Absolutely! Seasoning the onion before grilling can enhance its flavor. You can drizzle the onion slices or wedges with olive oil, sprinkle them with salt, pepper, and any desired herbs or spices. This will give the onion a delicious flavor profile while grilling.

How long should I grill the onions for?

Grilling time for onions can vary depending on the heat of your grill and the desired level of caramelization. Typically, it takes about 8-10 minutes, flipping once halfway through, to achieve a nicely grilled and softened onion. Keep an eye on them to prevent burning.
