Sharing is caring!

There is nothing the Weber Q can’t do, from roasting the crunchiest potatoes, carrots, pumpkin and sweet potato. To the juiciest pork or lamb.

My Weber Q roast vegetables will complement just about everything.

Topped with the right balance of herbs and combined with that smokey bbq flavour, even the kids will love them.

Weber Q Roast Vegetables

I don’t know what it is, but do you find that roast veggies taste better in Winter? I know I do.

Maybe it’s because they warm the tummy, much like soup does.

We tend to cook on our Weber Q much less in Winter because we don’t want to go out into the cold while the rest of the family is toasty inside.

What makes this recipe so great is most of the work is inside where the heater is.

So if you are feeling like a plate of vegetables on a wintery cold night, you have to give these bad boys a go.

They will taste better than roasting in an oven.

Best Vegetables To Roast In The Weber Q?

For my family and me, it’s

  • Potatoes
  • Sweet Potato
  • Pumpkin
  • Carrots

There are certainly many other options to choose from:

  • Asparagus
  • Eggplant
  • Zucchini
  • Turnips
  • Broccoli & Cauliflower
  • Corn
  • Squash
  • Onion
  • Capsicum (Peppers)

So as you can see, there are some great alternatives.

Whatever you decide, add salt, pepper and your favourite herbs to enhance and add flavour to your veggies.

Roast Them Small Or Roast Them Large?

I have noticed when looking around online that other recipes appear to cut their vegetables into small bite-sized pieces. So I thought I would be a little bit different.

Mum used to cut her veggies in large pieces when I was a kid. So this method of roasting carried over to me.

But damn, her roast veggies were good.

I find nothing better than slicing a roast potato in half and sliding butter inside, and letting it melt. Yummy!

To Parboil or Not to Parboil?

That is the question.

I do. I find my Weber Q roast vegetables to have a soft and fluffy texture inside but maintain a crunchy/firm exterior depending on the vegetable I am roasting.

Parboiling not only helps the vegetables to cook quicker. It will also help crispy up the skin we all love on our roast potatoes.

I parboil the potatoes and sweet potato for around 10 minutes after the water starts to boil for this recipe.

You are welcome to parboil your pumpkin, but I don’t recommend doing this with carrots because of their size.

Don’t Cheap out with the Oil

A good quality olive oil is key to wonderfully roasted veggies.

Adding a generous amount of olive oil will give your veggies a slick, glossy coating, helping them crisp up and adding a rich flavour that makes roasted vegetables irresistible.

Time to Fire Up Your Weber Q

Pop a new convection tray onto your grill and place the trivet on top.

Fire up your Weber Family Q by turning both gas control knobs to the START/HI position and close the lid.

For Weber Baby Q, turn the single gas control knob to the START/HI position.

Allow your Weber to heat up for 10-15 minutes, giving you time to get your veggies ready.

How to Prepare Weber Q Roast Vegetables? – Step 1

If you are slicing your potatoes into larger pieces similar to mine, cut them in half so you can get more out of them.

Please don’t go too small; we will be roughing them up later to get that crunchy outside.

Cutting potatoes too small will make them almost disintegrate.

Place your potatoes into a pot of water, and begin peeling and cutting your sweet potatoes into your desired size.

After the sweet potato is parboiled, it has a sticky consistency, so there is no need to rough them up.

Pop those into the pot with your potatoes.

To assist that crunchy potato skin we all love, add salt and bi-carb soda.

Bring your potatoes up to a boil and simmer for 10 minutes.

I explained why I do this in my Weber Q Roast Potatoes Recipe if you would like more information.

Finally, cut up your favourite pumpkin and carrots.

Pumpkin can take longer to roast than carrots and potatoes. So it’s essential to consider the size when cutting them into pieces.

But if they happen to be larger, pop them into the Weber Q for around 15-20 minutes before adding the rest of the veggies.

How to Prepare Weber Q Roast Vegetables? – Step 2

When the potatoes have been parboiled, strain them in a colander, separating the sweet potato and allow some time for them to cool.

Gently toss the potatoes around the colander until they have soft spikey edges and place them onto a flat tray.

Now to the best part.

I love experimenting with herbs to enhance the flavours. And playing around with the right combination of herbs and spices when it comes to veggies is crucial.

But remember, less is more!

I use garlic salt to assist with the crunchiness of the potatoes and some rosemary, thyme, and black pepper. It works a treat and tastes excellent.

Drizzle some olive oil, and sprinkle herbs and spices over the potatoes and sweet potatoes.

Place your pumpkin and carrot into a bowl, drizzle olive oil and sprinkle rosemary, thyme, fresh parsley, garlic salt, and black pepper and toss until the vegetables are fully covered.

How to Cook Roast Vegetables on the Weber Q?

Once all of your veggies are seasoned and ready to roll, open the lid of your Weber and begin placing all of your vegetables.

If your pumpkin is a little larger, make sure to get those onto the Weber 15 minutes earlier.

Place the potato, sweet potato and carrot onto the trivet and close the lid.

If you are cooking on the Family Q, turn the small gas control knob to the off position and the large gas control knob to the medium/roast position.

Baby Q, turn the single gas control knob to the Medium/Roast Position.

Try to maintain a temperature between 190°C (374°F) 230°C (446°C) at all times.

Using a wireless thermometer such as Weber’s iGrill 2 can help if you don’t have a thermometer on the lid of your Q.

Roast your veggies for about 1 hour to 1 hour 15 minutes or until golden brown.

  • 4 Potatoes (large) (note 1)
  • 1 Sweet Potato (medium)
  • 1/4 Jap Pumpkin (medium) (note 2)
  • 4 Carrots (large)
  • 1 tbsp Garlic Salt
  • 1 tbsp Rosemary dried
  • 1 tbsp Thyme dried
  • Olive Oil extra virgin (note 3)
  • 1/2 tbsp Baking Soda (bi-carb)
  • 1/2 tbsp salt


Preparing The Vegetables

  • Peel potatoes, sweet potato, and carrots. Cut the potatoes in half and slice up the sweet potato, carrots, and pumpkin into desired sizes. (note 4)
  • Half fill a large pot with water and stir in salt and baking soda (bicarb). In the water, place the potatoes and sweet potato. Bring to the boil and simmer for around 10 minutes until the potatoes feel soft. Then strain in a colander and allow to cool.
  • In a large mixing bowl place sliced pumpkin and carrot and drizzle olive oil over the vegetables. Add 1/2 tbsp of garlic salt, rosemary, and thyme to the bowl and gently toss until the pumpkin and carrot have mixed well with the herbs. Season with black pepper if desired.
  • When the potatoes have cooled, separate the sweet potato from the colander, these will not need roughing up. Toss the potatoes around in the colander until they form rough edges.
  • Place the potatoes onto a large plate with the sweet potato and drizzle with olive oil. Season the potatoes with a 1/2 tbsp of garlic salt, rosemary, and thyme.

Roasting the Vegetables on the Weber Q

  • Place a new convection tray onto the Weber Q, then place the trivet on top. (note 5)
    Family Q Owners, turn the large and small gas control knob to the START/HI position and ignite the grill. Baby Q owners do the same with the single gas control knob, and close the lid.
    Allow the Weber to preheat for 15 minutes.
  • Please Note: Place the pumpkin onto the trivet 15-20 minutes earlier then the rest of the vegetables. (note 6)
    When the Weber has preheated, begin placing the vegetables onto the trivet.
  • Close the lid and turn the small gas control knob off and the large gas control knob to the medium roasting setting.
    For Baby Q, do the same with the single gas control knob, and close the lid.
  • Try to maintain a temperature range at all times between 190°C (375°F) and 230°C (446°F) for 1 to 1 hr 15 minutes.
  • The vegetables are ready when the potatoes have reached an internal temperature of 98°C (208°F). or when golden brown.
  • Place roasted vegetables onto a serving tray and allow to cool for 5 minutes, then serve.


  1. Use any potatoes that you desire, I chose brushed potatoes, because of their suitability for roasting. They have a higher starch which makes them soft and fluffier inside.
  2. For this recipe, I am using Jap pumpkin. If you prefer something different then Grey or Butternut pumpkin are great alternatives. I don’t recommend Jack-o-Lantern pumpkin, as it’s not very nice to eat roasted.
  3. I use olive oil because it helps to make the vegetables crunchy. Another alternative to olive oil is duck fat.
  4. Try to cut potatoes and sweet potato into large sizes. They will need to be parboiled and roughed up to get a crispy edge. Too small and they will fall apart.
  5. If you don’t have a Weber Q convection tray, you can make your own by doubling over a large sheet of heavy-duty aluminium foil.
  6. Give your pumpkin a head start on the Weber. This is because it wasn’t parboiled and will need extra time to roast.
