Grilling and Smoking at High Altitude

At high altitude, air pressure is lower, water boils at a lower temperature, and fires burn differently. Cooks may find food dries out faster and takes longer.

Lower boiling point

Water boils at a lower temperature at elevation, so moist-heat cooking and evaporation behave differently. Foods lose moisture faster.

Longer cooking times

Expect some cooks to take longer. Always cook to internal temperature.

Charcoal and airflow

Thinner air means less oxygen per breath; charcoal may need more vent opening.

Gas grills

Gas grills may perform differently at elevation. Check the manufacturer's guidance.

Thermometer calibration

When calibrating in boiling water, use the boiling point for your elevation. See thermometer calibration.

Keeping food moist

Use brines, water pans and wrapping. See dry brine guide.

Why altitude changes cooking

At sea level, water boils at 212°F. As you climb, air pressure drops and water boils at lower temperatures, roughly one degree Fahrenheit lower for every 500 feet or so of elevation. That matters for grilling and smoking in several ways. Moisture evaporates from food more readily, so meats can dry out faster. Water pans in smokers evaporate more quickly and hold lower temperatures. Braising liquids and foil-wrapped cooks top out at a lower temperature, so tough cuts can take longer to become tender. None of this changes the internal temperatures food must reach to be safe; it changes how long and how gently you get there.

Adjusting low-and-slow smoking

For brisket, pork shoulder and ribs, expect cooks to run longer at elevation, and plan extra time. Keep your smoker temperature steady and rely on internal temperature and probe tenderness rather than the clock. Wrapping in butcher paper or foil during the stall helps retain moisture; because the liquid inside the wrap can't get as hot at altitude, the stall may last longer. A water pan helps with humidity but needs refilling more often. See wrap timing and the stall and how long to smoke pork shoulder.

Adjusting hot and fast grilling

Steaks, burgers and chops cooked quickly over high heat are less affected by altitude than long cooks, but dry air and wind can still speed up moisture loss. Pat meat dry for a better sear, don't overcook, and rest meat before slicing. Thinner cuts may cook through quickly; thicker cuts benefit from the reverse sear. See reverse sear method.

Fuel and fire management at elevation

Charcoal needs oxygen, and there's less of it per volume of air at elevation. You may need to open vents more than you would at sea level to reach the same temperature, and fires can take longer to get going. Use a chimney starter or electric starter to get charcoal fully lit. Propane grills rely on a fuel-air mixture; many work fine at moderate elevations, while some manufacturers offer guidance or parts for high altitude. Cold temperatures and wind, common in the mountains, also affect performance; see grilling in cold weather.

Camping and cooking in the mountains

For camp grilling at elevation, bring more fuel than you think you'll need, shield grills from wind, and keep food safety tools like a thermometer and cooler with ice. See portable grills for camping.

Food safety reminders

Safe internal temperatures don't change with altitude, and slow cooking means food spends longer warming up. Keep raw meat cold until cooking, avoid leaving food in the danger zone, and use a calibrated thermometer. See food safety temps.

Baking and pizza at altitude

Dough behaves differently at elevation, often rising faster. If you bake pizza on the grill at altitude, watch dough closely and adjust hydration and proofing times.

Our bottom line

At altitude, plan for longer cooks, keep meat moist with brines, wrapping and water pans, open vents a little more for charcoal, calibrate your thermometer for your local boiling point, and always cook to safe internal temperatures.

Checking doneness at altitude

Because cooking times shift at elevation, rely on internal temperatures rather than times from recipes written for sea level. For barbecue cuts that need to become tender, use probe tenderness as a guide once they're near target temperature. Rest meats after cooking; carryover cooking still occurs.

Planning cook times

Build buffer time into long cooks at altitude. Starting earlier and holding finished meat in a warm cooler or low oven is easier than rushing the end. See resting and holding meat.

Charcoal quantity

Expect to use somewhat more charcoal at altitude, especially for long cooks and in cold or windy conditions. Keep extra fuel on hand.

Gas grill tips at altitude

If your gas grill struggles to reach high temperatures at elevation, check the manufacturer's guidance for high-altitude operation, keep burners clean, preheat longer with the lid closed, and shield the grill from wind. Propane tanks also deliver less pressure in cold temperatures, common in mountain evenings.
