Infrared grills use radiant heat to sear at higher temperatures, while gas grills rely on convective heat for even cooking. Choose infrared if you want steakhouse-quality sear and faster preheat; choose gas for versatility, lower upfront cost, and easier temperature control.

Quick Answer

Infrared grills heat up faster and sear better but are pricier and require more careful cleaning. Gas grills are more versatile, cheaper, and easier to maintain but don’t reach the same peak temperatures.

  • Heat-up time: Infrared grills reach 700-900°F in under 10 minutes; gas grills take 10-15 minutes to reach 500-600°F.
  • Max temperature: Infrared: 900°F+; Gas: 600-700°F typical.
  • Flavor: Gas grills produce more smoke from drippings, adding smoky flavor; infrared vaporizes drippings instantly, reducing smoke.
  • Fuel efficiency: Infrared uses less propane/NG per high-heat session because of direct radiant transfer; gas uses more fuel for same cook time at lower temps.
  • Maintenance: Infrared burners and ceramic tiles need careful cleaning to avoid clogging; gas grills have simpler burner tubes and drip trays.

How Infrared Grills Work

Infrared grills use a gas or electric heat source to heat a ceramic or metal plate until it glows red. The plate emits infrared radiation that directly heats the food without heating the air around it. This allows the grill to reach temperatures above 900°F, searing meat quickly and locking in juices. The heat is intense and concentrated, ideal for thin steaks, burgers, and fish that benefit from a fast crust.

Common infrared designs include built-in infrared burners on gas grills (like the Weber Summit series) and standalone units such as the Char-Broil TRU-Infrared. The ceramic plate or emitter requires periodic cleaning to prevent grease buildup that can cause flare-ups.

How Gas Grills Work

Traditional gas grills use propane or natural gas to create flames that heat metal bars, lava rocks, or ceramic briquettes. The heat then circulates via convection around the food, cooking it more evenly but at lower peak temperatures (typically 500-600°F). The drippings from food fall onto the heat source, creating smoke that adds a classic barbecue flavor.

Gas grills offer precise temperature control through adjustable knobs, making them suitable for slow-cooking ribs or roasting vegetables. They are widely available at lower price points, with models like the Weber Spirit and Napoleon Rogue being popular choices. Maintenance involves cleaning the burner tubes and replacing flavorizer bars every few years.

Pros and Cons of Infrared Grills

  • Pro: Very high heat (700-900°F) for superior searing and crust formation.
  • Pro: Faster preheat – ready in 5-10 minutes.
  • Pro: More fuel-efficient at high temperatures because heat transfers directly to food.
  • Con: Higher upfront cost – infrared models typically cost more than comparable gas grills.
  • Con: Less forgiving – food can burn quickly if not watched closely.
  • Con: Not ideal for low-and-slow cooking; temperature control is less precise at lower settings.

Pros and Cons of Gas Grills

  • Pro: Lower purchase price – good three-burner gas grills start at a moderate investment.
  • Pro: Versatile – works for searing, roasting, and smoking with added wood chips.
  • Pro: Easy temperature control – knobs allow fine adjustments for different foods.
  • Con: Lower max heat (around 600°F) – can’t achieve the same sear as infrared.
  • Con: Longer preheat time (10-15 minutes) and more fuel used for high-heat cooking.
  • Con: More parts to maintain – burner tubes, valves, and flavorizer bars can corrode over time.

Which Grill Should You Choose?

Choose an infrared grill if you prioritize steakhouse-quality sear, fast preheat, and don’t mind a higher initial cost and steeper learning curve. Infrared excels for thin cuts and high-heat grilling but struggles with delicate foods like vegetables or low-temperature smoking.

Choose a gas grill if you want a budget-friendly, versatile cooker that handles everything from burgers to whole chickens. Gas grills are better for beginners and for those who need consistent results across a range of cooking styles. Many gas grills also have an infrared sear burner as an add-on, giving you the best of both worlds.

For most home cooks, a quality gas grill with a dedicated infrared sear station offers the ideal balance. Look for models with at least 30,000 BTU total output and a stainless steel burner system.

Pro Tips

  • Use an infrared grill for thin steaks (1 inch or less) – the intense heat cooks them quickly without overcooking the interior.
  • On a gas grill, create a two-zone fire by lighting only one side for indirect cooking of thick cuts or whole poultry.
  • Clean infrared ceramic plates gently with a brass brush to avoid cracking; never use water on a hot plate.
  • For extra smoke flavor on a gas grill, use a smoker box filled with wood chips placed directly over the burner.

Common Mistakes to Avoid

  • Cooking frozen food on an infrared grill – the intense heat can burn the outside while leaving the inside raw.
  • Using high heat on a gas grill for too long – it can warp thin grates and cause grease fires.
  • Neglecting to preheat an infrared grill – placing food on a cold plate leads to sticking and uneven cooking.
  • Overloading a gas grill with food – blocking airflow reduces heat and causes uneven cooking.

FAQ

Can I use an infrared grill for slow cooking?

Infrared grills are not ideal for low-and-slow due to their high base temperature. Some models have adjustable settings, but they lack the stable low heat of a gas grill. For slow cooking, stick with gas or charcoal.

Do infrared grills use more gas than gas grills?

At high heat, infrared grills are more fuel-efficient because energy transfers directly to the food. However, if you cook at moderate temperatures, a gas grill may use less fuel overall. It depends on your cooking habits.

Which grill is easier to clean: infrared or gas?

Gas grills are generally easier to clean because you can remove and wash grates and drip trays. Infrared grills require careful brushing of the ceramic plate to avoid damage, and grease buildup can be trickier to manage.

The Bottom Line

Ultimately, the choice between infrared and gas grills comes down to your cooking style. If you love a perfect sear and quick cooks, go infrared. If you want versatility and ease of use, gas is the safer bet. Many enthusiasts end up owning both, but for a single grill, a hybrid model with an infrared sear burner gives you the best of both worlds.
