The short answer
The best natural gas grill for most homes is the Weber Genesis in its natural gas version: excellent heat control, a sear zone on many configurations and a long warranty. The Weber Spirit natural gas model is the value pick, the Napoleon Prestige 500 is the premium choice with infrared rotisserie and sear options, and the Broil King Signet suits people who want a heavy, heat-retaining cooking box. Always buy a grill sold as a natural gas model, or one the manufacturer approves for conversion, and have the gas line installed by a licensed pro.

How we picked
We compared manufacturer specifications, warranty terms, owner reviews and published reviews from grilling and home publications. For natural gas grills we also checked whether each model is offered as a factory natural gas version, which is the simplest and safest route, and favored brands with good parts availability, since a fixed-line grill tends to stay in place for many years.
Why go natural gas?
- No tanks to refill: you never run out mid-cook or haul tanks to the store.
- Lower running cost in many areas: natural gas from the utility is often cheaper per unit of heat than bottled propane, depending on local rates.
- Tidy installation: a fixed line works well for permanent patio setups and outdoor kitchens.
The trade-offs: the grill is tied to where the gas line ends, installation costs money, and you can’t simply use a propane grill on natural gas. Natural gas and propane run at different pressures and need different orifices; only use a manufacturer-approved conversion kit, installed as the manufacturer directs, or buy a dedicated natural gas model.
1. Weber Genesis (natural gas): best overall
The Genesis line is Weber’s premium mainstream grill, redesigned in recent years with a larger cooking area, a sear zone on many models and a wide prep and storage area. Weber’s burners and heat-distribution system give even temperatures, and the brand has strong parts availability and a long warranty on key components. The three-burner E-325 and S-325 suit most families; larger versions cover big gatherings.
Good to know: Weber builds dedicated natural gas versions. Order the NG model rather than converting a propane unit, and check the warranty terms for your exact model.
Choose it if: you want a grill that will last many years with even heat and easy parts replacement.

2. Weber Spirit E-325 (natural gas): best value
The Spirit is Weber’s more affordable line. The E-325 has three burners in a compact footprint that suits smaller patios. It cooks very much like a Genesis for everyday burgers, chicken and steaks.
Good to know: it has less side-shelf space and fewer premium touches than the Genesis.

3. Napoleon Prestige 500 (natural gas): best premium
The Prestige 500 is a stainless steel grill with four main burners and, depending on the configuration, an infrared rear burner for rotisserie cooking and an infrared side SIZZLE ZONE for steakhouse searing. It’s a favorite among owners who want rotisserie chicken and high-heat searing without building a full outdoor kitchen.
Good to know: Napoleon sells several Prestige 500 versions; verify the listing is natural gas and includes the features you want.

4. Napoleon Rogue XT 425 (natural gas): best mid-range
The Rogue XT brings Napoleon’s build quality to a lower price. Configurations with a side burner (or infrared side burner) add flexibility for sauces and searing. It’s a strong alternative to the Weber Spirit for buyers who want stainless details.

5. Broil King Signet (natural gas): best heat retention
Broil King’s Signet line uses heavy cast cooking grids and a heat-retaining cookbox design, which owners like for strong searing and steady roasting. Broil King also offers rotisserie-ready configurations.

6. Char-Broil Performance (natural gas): best budget
If budget is the priority, Char-Broil sells natural gas versions of its Performance grills. They cover the basics well for everyday grilling. Expect a shorter life than premium grills, especially in wet climates, and use a cover.

Installing a natural gas grill
- Hire a licensed plumber or gas fitter to run the line and install a shut-off valve near the grill. Many areas require a permit.
- Use a quick-disconnect hose rated for natural gas so you can move the grill for cleaning.
- Check clearances in the grill’s manual: distance from walls, railings and overhangs.
- Leak-test every connection with soapy water before first use; bubbles mean a leak.
- Never connect a propane grill straight to a natural gas line, or vice versa.
Sizing guide
| Household | Main burners | What to look for |
|---|---|---|
| 1–3 people | 2–3 | Compact footprint, sear zone |
| 4–6 people | 3–4 | Side burner or side shelf, warming rack |
| Frequent entertaining | 4–6 | Rotisserie, infrared sear, larger primary area |
Buying checklist
- Confirm the exact listing is the natural gas version, or that the manufacturer sells an approved conversion kit for your model.
- Plan the grill location around the gas line, prevailing wind and clearance requirements.
- Compare warranties on burners, cookbox and lid.
- Look for stainless or porcelain-enameled cast-iron grates for durability.
- Budget for professional installation in addition to the grill itself.
FAQ
Can I convert a propane grill to natural gas?
Only if the manufacturer offers an approved conversion kit for that model, installed as directed. Natural gas and propane use different pressures and orifice sizes, so improvised conversions are unsafe.
Is natural gas cheaper than propane for grilling?
In many areas yes, because utility natural gas often costs less per unit of heat than bottled propane. It depends on local rates.
Do natural gas grills get as hot as propane grills?
A grill built or properly converted for natural gas is engineered to deliver comparable performance. Problems usually come from undersized gas lines or incorrect conversions.
Who should install a natural gas grill line?
A licensed plumber or gas fitter. Many jurisdictions require a permit, and a shut-off valve should be installed near the grill.
What is the best natural gas grill brand?
Weber, Napoleon and Broil King are consistently well regarded for natural gas grills because they offer factory natural gas versions, good parts availability and solid warranties.
