Cook over coals, never over flames. Let the fire burn down for 45 to 60 minutes until you have a glowing bed covered in grey ash, then rake it level and set your grate about four inches above it. Flames scorch the outside while the middle stays raw; coals give steady, even heat that lasts an hour or more.
That single idea fixes most fire pit cooking. Everything below is how to judge that heat, what gear earns its place, and how to avoid giving anyone food poisoning at the end of it. The same rules cover campfire cooking at a campground ring, since a fire pit and a fire ring behave identically once the flames drop.
At CamperishTrails we’ve cooked on backyard pits, campground rings, and one memorably terrible beach fire made of driftwood and optimism. The pattern never changes. People who wait for coals eat well. People who cook over flames eat charcoal.
Why Coals Beat Flames Every Time
A flame is not a cooking surface. It’s a moving column of burning gas whose temperature swings wildly and whose position changes with every gust of wind.
Coals are the opposite. A deep bed of embers radiates steady heat from a fixed distance, which is exactly what you need to cook something through without incinerating the surface.
There’s real chemistry behind wanting that heat rather than just any heat. The browning that makes fire-cooked food taste like fire-cooked food comes from the Maillard reaction, and the Exploratorium notes these reactions happen at temperatures above 140°C, around 280°F, which is why a high-heat method is needed to get a proper crust. Water alone tops out at 212°F, nowhere near hot enough. Coals get you there and hold you there. Flames overshoot and then vanish.
The practical rule: if you can see flames licking the grate, you’re too early. Wait. Cooking over coals is a patience problem before it is a skill problem.
Building the fire is its own job, and we’ve covered it in detail in our guide to building a campfire. For cooking specifically, burn hardwood if you have it and give it a solid hour of fuel-sized wood before you expect a usable bed.
Reading the Heat: The Hand Test
You can’t stick a thermometer in a fire pit and learn anything useful. What matters is the heat arriving at grate level, and your palm measures that better than any gauge.
Hold your open palm about five inches above the grate, roughly where the top of a soda can would sit if it were standing there. Count how long you can keep it there before you have to pull away.
| Seconds before you pull away | Heat level | Good for |
|---|---|---|
| 2 to 4 | High | Searing steak, chops, burgers |
| 5 to 7 | Medium | Chicken pieces, sausages, fish, vegetables |
| 8 to 10 | Low | Slow cooking, warming, anything with sugar or sauce |
Pull your hand away before it hurts, not after. Push your sleeves up first. Nothing dangling.
These are our working numbers and they’re approximate; published ranges vary a little between sources, and a windy night reads differently from a still one. Use them to compare one part of your fire to another rather than as absolute temperatures.
Build Two Zones, Always
This is the single upgrade that turns fire pit cooking from stressful to relaxed.
Rake your coals so roughly two thirds of the pit has a deep bed and one third has almost none. Now you have a hot zone and a safe zone.
Sear over the hot side. The moment something threatens to burn, or the fat starts flaring, slide it to the cool side and let it finish gently. No panic, no scraping black bits off a chicken thigh.
The cool zone is also where you park things that are done while the rest catches up, which matters when you’re feeding several people off one grate.
A depth worth knowing: aim for a coal bed two to three inches deep in the hot zone. Thinner than that and it dies halfway through dinner.
The Gear That Earns Its Place
You need less than the internet suggests. This is the short list.
A grate. Plain steel or cast iron. Sturdy enough not to sag, with legs or a way to sit four to six inches above the coals. Adjustable height is a genuine luxury.
A cast iron skillet. Handles direct coal contact, holds heat when you add cold food, and doesn’t care about scratches. The single most versatile thing you can own for this.
Heavy-duty foil. Not the thin stuff. For packets, for lining, for improvising a lid.
Long tongs and heat-resistant gloves. Standard kitchen tongs put your knuckles about eight inches from glowing coals. Get the long ones.
A food thermometer. Non-negotiable, and the reason is in the food safety section below. It belongs on the first-time camping checklist alongside the tongs.
Skewers. Metal, or wood soaked for half an hour.
A Dutch oven is the other serious option, and it deserves more space than we can give it here. Sizing, seasoning, and coal placement will get their own full guide in Dutch ovens at camp.
One warning about grates. Do not cook over galvanized or zinc-coated metal. Heating zinc-coated metal releases zinc oxide fumes, which the CDC lists as a hazardous inhalation exposure causing metal fume fever. If a grate came off a fence panel or a bit of ductwork, it doesn’t belong over your dinner. Use food-grade steel or cast iron.
Five Methods, Compared
Each does something the others can’t. Pick by cleanup, not ambition.
| Method | Difficulty | Cleanup | Best for | Watch out for |
|---|---|---|---|---|
| Direct on the grate | Easy | Medium | Steaks, burgers, sausages, corn | Flare-ups from dripping fat |
| Foil packet | Easiest | None | Fish, potatoes, mixed vegetables | Steams rather than browns |
| Cast iron skillet | Easy | Medium | Eggs, pancakes, anything that would fall through | Handle gets ferociously hot |
| Dutch oven | Hardest | High | Stews, chili, bread, cobbler | Needs coals above and below |
| Skewer or stick | Easy | None | Kebabs, sausages, marshmallows | Uneven cooking, needs turning |
Foil packets are the beginner’s friend. Set them directly on coals rather than on the grate, give them eight to twelve minutes depending on contents, and rotate once. They steam more than they brown, which is why they’re forgiving.
Cast iron wants preheating. Put the empty skillet on the grate for five minutes before anything goes in it. Cold cast iron sticks; hot cast iron releases.
Matching Food to Heat
The most common failure isn’t technique. It’s putting the wrong food over the wrong zone.
| Food | Heat zone | Method | Rough time |
|---|---|---|---|
| Steak, chops | High, then cool | Grate | 3 to 4 min a side, then finish |
| Burgers | Medium-high | Grate | 4 to 5 min a side |
| Sausages | Medium | Grate or skewer | 12 to 15 min, turning |
| Chicken pieces | Medium, cool to finish | Grate | 25 to 35 min, turning |
| Fish fillets | Medium | Foil packet or skillet | 10 to 15 min |
| Potatoes, root veg | Medium | Foil packet in coals | 30 to 45 min |
| Peppers, onions, corn | Medium | Grate or foil | 10 to 15 min |
| Eggs, pancakes | Low to medium | Cast iron | 3 to 8 min |
Times are a starting point, not a promise. Fire varies. That’s what the thermometer is for.
Food Safety Over a Fire
Recipe roundups skip this. It’s the part that can make someone ill.
Cook to temperature, not to colour. Clemson Extension is direct about this: colour changes in meat are no longer considered reliable proof that bacteria have been destroyed. Firelight makes this worse, because everything looks browner than it is.
| Food | Minimum internal temperature |
|---|---|
| Beef, lamb, veal (steaks, chops, roasts) | 145°F, then rest 3 minutes |
| Fish | 145°F |
| Ground beef, lamb | 160°F |
| All poultry, including ground | 165°F |
| Leftovers and reheated food | 165°F |
| Eggs | Cook until yolk and white are firm |
Purdue Extension’s outdoor food safety guidance specifies cooking whole cuts of beef, pork, lamb and veal to a minimum internal temperature of 145°F, allowing the meat to rest at least three minutes before carving.
Keep raw and cooked apart. Clemson Extension’s camping guidance says to use a separate cutting board or plate for produce and another for raw meat, and that cooked food should never go back on a plate that held raw meat, poultry, seafood or eggs unless it has been washed with hot soapy water. The classic campsite mistake is carrying raw burgers out on a plate and then stacking the cooked ones back on it.
Watch the clock. The CDC advises never leaving perishable food out for more than 2 hours, or 1 hour if it’s above 90°F. Cold food should be held at 40°F or below, which is a cooler job — and coolers get their own guide.
Wash your hands properly. Purdue’s guidance is blunt about the practicalities: soap and water are essential, so if you’re going somewhere without running water, bring water with you. It also advises against relying on lake or stream water, however clean it looks.
Boil reused marinade. If you marinated raw meat in it and want to use it as a sauce, it has to come to a boil first.
What Should Never Go Under Your Food
Four things, and they all matter.
Treated, painted, or stained wood. The EPA’s guidance on chromated arsenical preservatives is explicit: do not burn preservative-treated wood. Old deck boards, pallets and fence offcuts are not fuel, and they’re certainly not cooking fuel.
Rocks in the fire pit. The Forest Service warns not to line a pit with rocks because they can explode when hot. A rock that fractures throws fragments at whoever is standing over it, which at cooking time is you.
Galvanized or zinc-coated metal. Covered above. Grates only.
Charcoal anywhere enclosed. The CPSC warns that people die every year from carbon monoxide poisoning after burning charcoal in enclosed areas such as tents, campers and vans. Never move a cooking fire, coals, or a chimney starter under cover for warmth.
And a category question people ask constantly: can you cook on a gas fire pit? Generally no. Decorative fire pits and fire tables aren’t built for it, dripping fat wrecks the burner and media, and the flame pattern is wrong for cooking anyway. We will go into the detail in our guide to gas fire pits.
When to stop and get help: if a grease flare-up spreads beyond the pit, or embers catch nearby grass, call 911 rather than trying to beat it out. Never throw water on a grease fire.
Six Mistakes That Ruin Fire-Cooked Food
- Cooking too early. The commonest one by far. If there are flames, you’re waiting.
- One heat zone. Nowhere to retreat to when something starts burning.
- Grate too low. Four to six inches above the coals. Two inches turns everything to carbon.
- Cold cast iron. Preheat five minutes or accept that eggs will weld themselves on.
- Guessing doneness. Firelight lies about colour. Use the thermometer.
- Cooking for a crowd off one small bed. Coals deplete. Keep a second small fire going alongside to feed fresh embers across.
That last one took us three trips to learn. Twelve sausages will strip a modest coal bed of its heat in about ten minutes, and there’s nothing to do at that point but wait.
When Dinner’s Done
Cooking leaves you with a fire that still needs killing properly, and food waste that shouldn’t go in it.
Burnt-on food doesn’t fully combust; it smokes, smells, and attracts animals overnight. Scrape plates into your rubbish, not the fire. Drifting food smoke is also on the wrong side of campground etiquette.
Then put it out properly. That means drowning, stirring, drowning again and feeling for heat, which we walk through step by step in putting out a campfire completely. A pit that cooked dinner holds heat longer than one that just burned wood, because you’ve usually been feeding it for hours.
For the wider question of running a whole outdoor kitchen (water, washing up, storage, stoves etc) start with setting up the kitchen zone so the kitchen items aren’t fighting each other. And there are shortcuts worth stealing in our camp meal hacks, in our camp meal hacks.
Frequently Asked Questions
Yes, on a wood or charcoal-burning pit. Wait for coals rather than flames, use a grate or cast iron, and check food with a thermometer. Gas and decorative fire pits generally aren’t built for cooking.
Coals. Flames swing in temperature and position and will scorch the outside while the inside stays raw. A deep ember bed gives steady heat for an hour or more.
Roughly 45 to 60 minutes of burning fuel-sized hardwood. You want a glowing bed covered in grey ash, two to three inches deep.
Untreated, unpainted, seasoned firewood. Never treated, painted or stained wood, and never pallets or old deck boards.
Four to six inches for most cooking. Higher for anything with sugar or sauce that burns easily.
The hand test. Palm about five inches above the grate: 2 to 4 seconds means high heat, 5 to 7 medium, 8 to 10 low. Pull away before it hurts.
Yes. Cast iron is happy in direct contact with embers. Use gloves and long tongs, and remember the handle reaches the same temperature as the pan.
The fire is fine once it’s burning properly. The concern is the pit itself: don’t line it with rocks, which can explode when heated.
Go Cook Something
Fire pit cooking has a reputation for being difficult, and it isn’t. It’s just slower at the start than people expect.
Light the fire an hour before you’re hungry. Wait for the flames to die and the ash to go grey. Rake two zones. Hand test. Then cook the same way you’d cook anywhere, checking with a thermometer instead of guessing.
The first meal you get right this way is disproportionately satisfying, and it makes the whole evening better. Which, once the plates are cleared and the fire’s burning low, is the real point of the thing.
