How We Picked the Best Natural Gas Grill with Side Burner
We prioritized cooking performance, burner layout, build quality, usability, and overall value. For a Natural Gas Grill with Side Burner, the most useful features are consistent heat, enough primary cooking space for your household, and a side burner that is easy to access without crowding the main grill area.
We also looked at practical details like grates, BTU output, cabinet storage, ignition design, and whether the grill suits everyday weeknight cooking or larger weekend gatherings.
Quick Comparison: What Matters Most
In simple terms, smaller grills are easier to fit on patios and warm up quickly, while larger models give you more room for burgers, vegetables, and indirect cooking. If you cook for a family or host often, a 4-burner or 5-burner setup is usually the sweet spot. If you want serious capacity, step up to a larger cabinet-style or smart grill.
Best for Small Spaces
Compact models are ideal when patio footprint matters more than maximum output. You’ll still get the convenience of natural gas and a side burner without a huge frame.
Best for Frequent Entertaining
Larger 4-burner and 6-burner options are better if you want flexible zone cooking, extra searing space, and room to keep sides warm while the main grill is busy.
Key Buying Factors for a Natural Gas Grill with Side Burner
Cooking area: Make sure the main grate size matches how many people you usually feed. More space helps when you cook proteins and vegetables at the same time.
Burner count and heat control: More burners usually mean better zone control, which matters for searing, indirect roasting, and keeping delicate food away from high heat.
Side burner usefulness: A side burner is most valuable if you actually plan to simmer sauces, boil corn, or sauté vegetables outdoors. If you rarely use it, don’t overpay just for the feature.
Construction: Look for durable grates, a sturdy cart, and easy-to-clean surfaces. Stainless steel and porcelain-enameled components are common on stronger midrange and premium grills.
Fit and fuel setup: Since these connect to your home gas line, confirm placement, hose routing, and patio clearance before buying. This is especially important for a larger Natural Gas Grill with Side Burner.
Who Should Buy Which Natural Gas Grill with Side Burner?
If you want a simple, reliable everyday grill, a mid-size 3- or 4-burner model is usually the best balance of price and versatility. If you host regularly or cook multiple dishes at once, choose a larger 4+1 or 6+1 burner model for more flexibility.
If you have limited outdoor space, a compact grill may be the smarter pick. If you want the most cooking power and the most convenient setup for backyard meals, go with a full-size Natural Gas Grill with Side Burner that offers strong heat, stable construction, and enough space to cook without crowding.
