Infrared Gas Grill vs Conventional Burners: Is Infrared Worth It?
Infrared grills promise steakhouse searing, faster preheats and fewer flare-ups. Some of that is real. But infrared also changes how a grill behaves at low heat, how it handles delicate food, and how you clean it.
This guide explains how infrared systems work, compares them with conventional burners on everyday cooking, and helps you decide between a full infrared grill, a conventional grill with an infrared sear zone, or neither.
Quick answer
- Conventional burners heat mostly by hot air (convection). Infrared systems put more of their energy into radiant heat aimed at the food.
- Infrared excels at fast, hard searing and recovers quickly after the lid opens.
- Many full-infrared grills are harder to run low and gentle, and can be less forgiving with fish, vegetables and chicken pieces.
- For most buyers, a conventional grill with one infrared sear burner covers both needs.
- Check how the infrared emitters are cleaned and whether replacement parts are available before buying.
How each system heats food
A conventional gas burner is a tube with ports along its length. The flames heat the air, heat tents above the burners spread and radiate some of that heat, and hot air circulates up through the grates. A good share of the cooking is done by hot air, plus conduction where food touches hot grates.
An infrared system puts a surface between the flame and the food that glows and radiates heat. Depending on the design, that surface might be a ceramic tile with many tiny ports, a metal mesh, or a glass or steel plate over a burner. The result is more radiant heat aimed straight at the food, and less reliance on hot air.
Radiant heat is very efficient at browning surfaces, which is why infrared is associated with searing. It also dries surfaces less with moving air, which manufacturers often cite as helping juiciness. That claim depends heavily on how you cook, so treat it as a possible benefit, not a guarantee.
Head-to-head on everyday cooking
| Task | Conventional burners | Infrared |
|---|---|---|
| Searing steaks and chops | Good with heavy grates and full preheat | Excellent; fast, intense crust |
| Preheat time | Moderate | Often faster to searing heat |
| Recovery after lid opens | Slower, especially in wind | Typically faster |
| Low and gentle heat | Easy | Can be harder on some designs |
| Fish, vegetables, chicken pieces | Forgiving | Easy to scorch if left on high |
| Indirect cooking | Straightforward with multiple burners | Possible, design-dependent |
| Flare-ups | More common | Often fewer, since drippings vaporize on hot surfaces |
| Wind sensitivity | Higher | Lower on many designs |
| Cleaning | Familiar: brush grates, scrape tents | Varies: some emitters burn clean, others need careful handling |
The three ways to get infrared
Full infrared grill
Every burner uses an infrared system. Best for people who sear most of the time and don't mind learning a different heat curve.
Conventional grill + sear burner
One zone is infrared for searing; the rest are conventional. The most flexible choice for most households.
Standalone infrared broiler
Compact, very hot top-down units for steaks only. A specialist add-on rather than a main grill.
If you're weighing a dedicated sear burner against simply using heavy cast iron, our sear burner vs cast iron guide covers that comparison.

Honest pros and cons
Where infrared earns its price
- Hard, fast sears on steaks, chops and burgers.
- Reliable heat in wind and cooler weather on many designs.
- Fewer flare-ups from fatty foods on many designs.
- Quick recovery when you open the lid to flip.
Where it frustrates
- Less forgiving with delicate foods. A few minutes too long on high can scorch fish and vegetables.
- Low-temperature control varies by design. Some infrared grills don't go as low as you might want.
- Ceramic emitters can crack if hit with cold water or impacts, and some are sensitive to food debris.
- Replacement emitters can be specific and pricier than conventional burners.
Who should buy what
| You mostly cook | Best fit |
|---|---|
| Steaks, chops, burgers, fast and hot | Full infrared or a grill with a large sear zone |
| A mix of everything, including chicken, fish and vegetables | Conventional grill with one infrared sear burner |
| Lots of indirect roasting and gentle cooking | Conventional grill; add cast iron for searing |
| Windy, exposed location | Infrared or a well-sealed conventional grill |
| Tight budget | Conventional grill with heavy grates |

Cooking on infrared: what changes
- Use less time and watch closely. Searing happens fast. Flip early and check often until you know your grill.
- Sear, then move. On a combo grill, sear over the infrared zone, then finish over a conventional burner on lower heat.
- Use the lid deliberately. Infrared heats the food surface directly; closing the lid adds oven-style heat for thicker cuts.
- Use a thermometer. An instant-read probe prevents overcooking when the outside browns quickly. Use the USDA's published minimum internal temperatures as your safety reference.
- Protect delicate foods. A grill basket or a perforated pan keeps fish and vegetables from scorching on high radiant heat.

Cleaning and maintenance
Many infrared systems are designed so drippings vaporize and residue burns off at high heat. Most manuals recommend a burn-off on high after cooking. Specific care varies a lot by design, so read your manual: some ceramic emitters shouldn't be brushed hard or exposed to water, and some systems sit under a protective grid or glass. Avoid pouring water on a hot infrared burner. Before buying, check that replacement emitters or plates are sold for the model.
Before you buy: checklist
- Decide whether you want full infrared or a sear zone.
- Check the manual for the lowest practical heat setting if you cook gently.
- Check emitter type and cleaning instructions.
- Check that replacement emitters and burners are available.
- Compare warranty coverage on infrared components specifically.
Common claims, checked
| Claim | Reality |
|---|---|
| “Infrared makes food juicier” | Possible with less air movement and faster cooking, but overcooking dries food on any grill. Technique matters more. |
| “Infrared uses less gas” | Some designs are efficient, especially in wind, but it depends on the grill and how you cook. |
| “Infrared never flares up” | Many designs reduce flare-ups, but fatty foods can still flare. |
| “Infrared is only for steak” | It's best for searing, but most foods can be cooked well with attention, especially on combo grills. |
| “Higher BTU means better searing” | Not on infrared. Radiant designs can sear hard at lower BTU ratings than tube burners. |
If you're comparing grills on BTU numbers, keep in mind that infrared and conventional burners can't be compared directly on that spec. Look at how the manufacturer describes the infrared zone's coverage and temperature range instead.
Cheaper ways to get better searing
If you already own a conventional gas grill and mainly want harder sears, you don't necessarily need infrared at all:
- Heavy cast iron grates store much more heat than thin wire grates and give stronger grill marks.
- A cast iron griddle plate or pan gives full-contact browning across the whole surface of the food.
- A longer, lid-closed preheat on high gets grates and tents fully saturated with heat.
- Dry the surface of the meat before cooking, since surface moisture must evaporate before browning begins.

FAQ
Is an infrared grill better than a regular gas grill?
For fast, hard searing, infrared is often better. For gentle cooking, delicate foods and indirect roasting, conventional burners are usually more forgiving. Most people are well served by a conventional grill with one infrared sear burner.
Can you cook low and slow on an infrared grill?
It depends on the design. Some infrared grills have good low-heat control; others run hot even on low. Check the manual and specs for the low setting before buying if gentle cooking matters to you.
Do infrared grills cause fewer flare-ups?
Often, yes. Many infrared designs vaporize drippings on hot surfaces before they can ignite into large flames. Fatty foods can still flare, so keep an eye on them.
How do you clean an infrared grill burner?
Most manuals recommend burning off residue on high after cooking. Specific cleaning depends on the emitter type, and some ceramic emitters shouldn't be brushed or exposed to water, so follow your manufacturer's instructions.
Bottom line
Infrared is a real upgrade for searing and for cooking in wind, but it's less forgiving for everything else. If you mostly cook steaks and burgers fast and hot, a full infrared grill can be a joy. For a household that grills a bit of everything, a conventional grill with an infrared sear burner gives you the best of both, and is easier to learn.
