How to Grill Vegetables Without Burning Them?

When the weather is nice, you enjoy being outside if you’re anything like me. However, when there are many people here, it’s easy to get distracted from the grill. It’s easy to burn your meat and vegetables when this happens. As a result, I questioned how to avoid burning vegetables on the grill.

Here’s what I found out after doing some research.

Don’t add too much oil or salt if you want your vegetables to burn on the grill. Too much oil can drop and cause flare-ups, and too much salt can leech moisture from the vegetables, making them dry up and burn more quickly. However, timing and temperature are equally important, with many just requiring 6-8 minutes at medium-high heat, rotating once.

But there’s a lot more to delicious grilled vegetables than that, so keep reading!

When grilling vegetables, what is the best oil to use?

When you barbecue with charcoal, wood, or propane gas, you’re usually doing so at high temperatures.

While many of us adore extra virgin olive oil, it isn’t necessarily the ideal option for cooking over high heat.


Olive oil only has a 375° smoke point (similar to a burn point). A basic gas grill can reach 450 degrees Fahrenheit, and wood or charcoal cooking can reach much greater temperatures.

The smoke point of canola oil, on the other hand, is 468°. Refined peanut oil has a temperature of 450°, vegetable oil (typically soy or a soy blend) has a temperature of 450°, and sunflower oil has a temperature of 478°.

As a result, any latter is superior to olive oil when used on a hot grill.

When grilling vegetables, what temperature should they be cooked at?

Of course, corn on the cob isn’t the same as bell pepper, and a thin zucchini slice isn’t the same as a zucchini slice.

As a result, there isn’t exactly a one-size-fits-all method to grill various vegetables.

The optimal times and temperatures for the most regularly grilled vegetables are listed below. To avoid burning your vegetables, follow these steps.

Grill the vegetables at medium heat (350°F).

  • Cobs of corn (in the husk, silk removed, and soaked in cold water at least 15 minutes) – 20 to 30 minutes (rotating during cooking)
  • Leeks are a type of leek that (cut in half down the stalk and brushed with oil) - Cooking time: 5 minutes per side.
  • Artichokes are a vegetable that grows in the Mediterranean (cut in half, brushed with oil) – Cooking time: 15-20 minutes per side.

Grill vegetables at a medium-high temperature (400-420°F).

  • 8 minutes peppers (cut in half and coated with oil) (skin side) three minutes (another side)
  • Onion is a vegetable (brushed with oil, cut into thick rings) - Duration: 8 minutes (flipping often)
  • Asparagus is a type of asparagus (brushed with oil, salt, and pepper) - Duration: 7 minutes (rotating often)
  • Eggplant is a type of vegetable (cut in half or thick circles, brushed with oil) - 4 minutes on each side
  • Mushrooms are edible mushrooms (remove stem, scrape out the gills, brush with oil) - 8 minutes on each side
  • Zucchini & squash (sliced longways in 3rds, brushed with oil and salt) - 6 minutes on each side

What method can I use to determine the temperature of my grill?

A thermometer is built into many grills.

Unfortunately, they frequently cease working after a short time, or the glass becomes so blackened that it is impossible to read. They’re also not taking into account the temperature of the grill’s surface, which is where your food is cooked.

It’s preferable to have a stand-alone grill thermometer so you can correctly determine how hot your grill is to avoid burning your grilled vegetables.

Riida manufactures the highest-rated thermometer.

Their TM08 Wireless Meat Thermometer is just fantastic! Examine all of the following features to discover if it’s not the PERFECT option for your grill, smoker, or BBQ:

  • Two probes are included to check the temperatures of two different types of meat (or one meat and the grill temp)
  • Set the alarm for when it reaches the ideal temperature or rises too high.
  • For meats, you may set it to notify you when it’s done to your liking (rare, medium, etc.)
  • Food-grade stainless steel probes are connected with heat-resistant steel mesh cables.
  • It comes with a wireless receiver that you can carry around with you and detect temperatures and alarms from up to 300 feet away!

How long does it take for a charcoal grill to reach the desired temperature?

This is where many inexperienced grillers go wrong.

I’m aware of this because I’ve done it numerous times. We fire the coals with lighter fluid a couple of times (as our spouses double-check that our life insurance coverage hasn’t expired).

After seeing the coals turn white and feeling some heat, we tend to put the food on too soon.

The coals then begin to flame (especially if the meal has been over-oiled or over-marinated), and the flames lick the food excessively, resulting in charred vegetables and meats.

While the thermostat I mentioned before is a useful tool, it does not indicate when your coals are ready.

After about 10 minutes, most of the charcoal will be completely white-gray.

They’re at a high temperature right now. As previously stated, most vegetables require medium to medium-high heat. As a result, we’ll have to wait.

As a result, you’ll want to hold off on adding the vegetables until about 20 minutes for medium-high and up to 30 minutes for medium.

When grilling vegetables in a basket, how long does it take?

By keeping vegetables confined inside a wire mesh holder, a basket helps keep them from scorching on the BBQ. It also keeps them from dropping through the grill grates, especially for smaller vegetables.

It also prevents them from sticking to the grill.

Larger vegetables, such as corn, don’t require a basket, but slices of onions, peppers, and squash must.

As I mentioned above, different vegetables require varying temperatures and periods, but most vegetables in a basket require medium-high heat (400-420°) for 6-8 minutes, flipping a few times during that time.

While some grill baskets have an open-top, I prefer a basket with a locking cover and handle since it makes flipping the vegetables a breeze.

Qualitech manufactures a wonderful one with three compartments, allowing you to prepare all vegetables, a combination of vegetables, meat, or even whole fish.

It has a detachable handle, gloves, and wooden locking handles to keep the food inside the basket rotating. Almost five stars, free shipping, and a budget-friendly price.

Do you brush your vegetables with oil before grilling them?

Before grilling, some so-called experts advocate coating vegetables with oil.

On the other hand, many other experts advise spraying oil onto the grill grates rather than the vegetables themselves. The reason for this is that as the oil heats up, it burns quickly, leaving your vegetables with a burnt and rotten flavor.

Before the flames die out, but after you’ve scraped the grates clean, pour some oil on a paper towel and wipe the grates to the point where they’re coated (but not dripping).

If you need to reapply the oil during cooking, pour it onto a cloth rag and use long tongs to brush it vertically and horizontally across the grates.

Oiling your grill grates every time you use them has the same beneficial impact as seasoning a cast iron pan. The grill grates become increasingly non-stick as they are seasoned.

If you must spray the vegetables with oil, do so sparingly!

When you use too much oil, it drips down into the embers or the inside of your gas barbecue. This can trigger flare-ups and leave a huge mess to clean up.

Flare-ups can cause your vegetables to burn and blacken outside before they are fully cooked on the inside.

Is it necessary to salt veggies before grilling?

Salt can be tricky.

For one thing, food tastes bland if you don’t use it or use too little of it. When you use too much salt, it tastes salty and dehydrates the food.

Dry vegetables are prone to burning because they cook too quickly. That translates to nasty, shriveled, and charred vegetables.

However, if you salt after grilling, the salt will scorch on the outside of the vegetables, so you will first taste the salt and then the vegetables.

Not fantastic, either.

The benefit of using a little salt is that it releases a small bit of moisture when grilling, and the salt tends to blend in with the flavor of the meal and caramelize gently on the outside.

So, my advice is to season them lightly before grilling and then liberally after they’ve been removed from the heat.

Do you start with the meat or the vegetables?

There are two points to examine here.

The first question is whether or not anyone in your party is a vegetarian. In that scenario, you should prepare the vegetables first to avoid offending your vegetarian guests.

However, grilling meat, particularly fatty meat, can leave a lot of residue on the grill grates.

While some believe that this imparts taste to meals cooked after that, it’s usually just burned marinade and oil, which isn’t particularly pleasant.

The second thing to remember if you’re using charcoal is that the coals reach their peak temperature after about 10 minutes, which is perfect for steak or corn on the cob (in the husk), but not so much for vegetables (or chicken).

So, in this case, grilling the meat first and then the vegetables would be a good idea.

If you’re cooking with propane, though, this isn’t an issue because you can easily control the heat. However, if you’re using a charcoal grill, you can add extra briquettes after grilling the vegetables and return to high heat in 10 minutes.

With all of these factors in mind, I believe that cooking vegetables first, then chicken or fish, and, if you’re grilling beef on a non-gas grill, adding more coals, waiting 10 minutes, and then grilling the meat, yields the greatest results.

Are grilled vegetables good for you?

It depends on your point of view, as it does with so much in life.

Grilling potatoes is undoubtedly healthier than deep-fried potatoes. What’s the difference between steaming and roasting? Not quite as much.

When many veggies are burned in any way, they eventually generate a chemical called acrylamide, and grilling is no exception.

Acrylamide is a suspected carcinogen. Hence it should be avoided. But, unless you’re aiming to switch to a raw foods diet, you’re already consuming some (besides, it’s in things like coffee, which I’m not giving up).

A healthy addition to your tiny kitchen appliances, on the other hand, is an air fryer. My partner gave it to me as a Christmas present, and I’ve been using it continuously since then.

Is it still safe to eat burned vegetables?

Of course, if they’re completely blackened, no one will want to eat them. However, we occasionally receive slightly charred ones.

Many foods emit a hazardous chemical called heterocyclic amines (HCAs) when burned on the barbecue. This has been connected to the development of cancer.

The good news is that this does not occur when grilling veggies, even if slightly charred or scorched.

However, charring vegetables release a recognized carcinogen called benzopyrene, created by cigarette smoke.

Try grilling using indirect heat to avoid this, as well as learning how to avoid burning your vegetables.

By putting the embers on one side of the grill and the vegetables on the other, you can achieve this. Turn the burner off under the vegetables on a propane grill.

Alternatively, laying the vegetables on a solid tray or aluminum foil helps to guarantee that they only receive indirect heat, which is important for avoiding benzopyrene.

Is it better to grill with charcoal or with gas?

This is a loaded question, and you’d receive ten different replies if you questioned ten different people.

To be certain, there are some differences between grilling with wood and grilling with charcoal.

So, if you’re not sure which is preferable, I strongly advise you to read my in-depth piece on the matter.

Finally, for flavor, real lump hardwood charcoal produces excellent results. However, the simplicity of a propane grill means it heats up quickly and maintains a consistent temperature, which is ideal for beginning grillers. This makes learning how to cook vegetables on the grill without scorching them a lot easier.

Several individuals are concerned about propane barbecues’ safety. You’re essentially barbecuing over open flames with a large gas tank! I decided to investigate the safety issues around propane grills. I wrote a brief piece covering the subject in great detail, including the two most common causes of propane tank explosions.
