How to Roast Marshmallows on a Fire Pit or BBQ

Nothing beats roasting marshmallows or smores over the open flame of a fire pit or a BBQ. But how do you do it the right way and get that golden, gooey result? Here are some tips and steps that work for both options.

All you need is a fire, a marshmallow, and a stick—then get toasting. As simple as that! But here’s the thing: many people let their marshmallow burn, either because they prefer it a bit more on the burnt side or because they lose control of it. Either way, these tips can help you get the perfect toast every time:

Find the right roasting stick

Old twigs are a classic, but there are now alternatives that are safer, more convenient, and ready to use. A long metal skewer or a cleaned wooden stick, for instance, does the job. They’re specifically made for roasting marshmallows, with:

• Extra length to keep your hands at a safe distance and reduce the risk of burns.
• A sturdy but lightweight build that won’t snap or burn, so your marshmallow doesn’t end up in the flames.

Moreover, wooden sticks don’t conduct heat as quickly as metal (like stainless steel), giving you better control when toasting. Designs vary—some are straight with a pointed end, while others are forked or double-pronged to stop marshmallows from spinning or falling off.

Make sure to keep these features in mind when looking for options.

Wait for the fire to die down a bit

A fire pit with big flames sets the mood, but it also burns your marshmallows. You’ll want to avoid that and instead wait until the flames die back, leaving mostly glowing embers.

Roasting over embers gives you more control, helping the inside warm through while the outside toasts perfectly. If you try to roast over open flames, the outside will burn long before the middle gets gooey.

Be patient; it makes all the difference between a nicely toasted marshmallow and a burnt one.

Positioning and rotating

Now that you know when to start roasting your marshmallows, the next step is where to hold them over the fire. Ideally, aim for about six inches above the coals—roughly the length of a pencil or the width of your hand from thumb to pinky when stretched out. That’s the sweet spot for the right temperature and even toasting.

Then, rotate the stick (like a rotisserie chicken) slowly and consistently for about five minutes. Don’t just hold it in the fire and leave it there.

You’re aiming for an even golden brown all over, and that’s when you know the outside is crisp while the inside stays soft and gooey. It will also melt the chocolate nicely for s’mores. Once it’s done, give it a few seconds to cool before taking a bite. Trust us, it’s hotter than it looks!

Note: If it catches fire, pull it out of the fire and blow it out. Be careful when doing this—a flaming marshmallow can drip hot, sticky sugar, which can cause burns. It can also relight if not properly extinguished, so make sure it’s out before carrying on.

How to Grill Marshmallows on a BBQ

If you’re looking for how to make s’mores on a BBQ, grilling marshmallows is a popular method. But instead of using a stick for one or two ‘mallows, you’ll need a skillet pan filled packed with marshmallows!

Here’s how to do it on a gas BBQ with just three steps:

1. Line a cast-iron pan with the biscuits (flat side down), then layer the chocolate on top. Cover it with marshmallows, and if you want it extra chocolatey, tuck some more chocolate between the marshmallows.
2. Turn one side of the BBQ to high heat and leave the other side off. Place the pan on the cooler side—this stops the bottom from burning while letting the top get nicely golden.
3. Close the lid and let it cook for 15–25 minutes, checking every 10 minutes. It’s ready when the marshmallows are golden, and the chocolate has melted.

If using a charcoal BBQ:

1. Instead of turning off a burner like on a gas BBQ, push the hot coals to one side of the grill, leaving the other side cooler. Place the cast-iron pan on the cooler side to prevent burning the bottom.
2. Charcoal can be less predictable than gas, so keep an eye on the temperature. You might need to adjust the coals or the pan’s position if it’s cooking too fast.
3. Charcoal heat varies, so check every 5–10 minutes rather than waiting 10–15 minutes like with gas. It’s ready when the marshmallows are golden, and the chocolate is melted.

Hold off for a few seconds before diving in, or you’ll end up with a burnt tongue.

And that’s how to roast or grill marshmallows (or s’mores) on a fire pit or BBQ!

For the best of both worlds, consider a fire bit BBQ which combines both!
