A side burner is an auxiliary cooking station installed alongside your main grill in an outdoor kitchen island. These burners operate independently from your primary grill, allowing you to prepare sauces, boil vegetables, simmer side dishes, or keep foods warm while grilling the main course.
Side burners connect to your outdoor kitchen’s fuel supply, either natural gas or liquid propane. The independent ignition and control systems enable simultaneous cooking at different temperatures than your main grill, effectively doubling your cooking capacity during outdoor gatherings.
The practical value becomes obvious during real-world cooking scenarios. I’ve prepared complete outdoor meals where the grill handles steaks at high direct heat while the side burner maintains a gentle simmer for herb butter sauce. This multitasking capability eliminates the constant back-and-forth to the indoor kitchen that disrupts outdoor entertaining.
BTU (British Thermal Unit) rating measures heat output per hour. For side burners, I recommend minimum 12,000 BTU for basic functionality and 15,000+ BTU for versatility. The difference becomes apparent when boiling water or searing sauces.
12,000-15,000 BTU: Adequate for simmering, light boiling, and warming. Expect 8-10 minutes to boil a medium pot of water.
15,000-20,000 BTU: Ideal for most home cooking. Boils water in 5-7 minutes and handles stir-fry adequately.
20,000+ BTU: Professional-level performance suitable for wok cooking and rapid boiling. Best for serious outdoor cooks.
The grade of stainless steel dramatically affects longevity. 304 stainless contains nickel and chromium that provide excellent corrosion resistance, especially in coastal or humid environments. 430 stainless lacks nickel and offers significantly less protection.
I’ve personally witnessed 430 stainless burners rust through within three years in mild climates, while 304 stainless models last a decade or more with basic maintenance. The upfront premium for 304 grade pays for itself by avoiding replacement costs.
Natural gas provides continuous fuel supply without tank changes, ideal for frequently used outdoor kitchens. Installation requires professional gas line routing and proper permitting.
Liquid propane offers flexibility for portable setups or locations without natural gas access. Tanks require monitoring and replacement, but many homeowners appreciate the independence from utility infrastructure.
Dual-fuel convertible models provide future flexibility. The conversion process involves replacing orifices and adjusting air shutters. Most DIY-capable homeowners complete the conversion in 30-60 minutes.
Standard cutout dimensions typically measure 12-14 inches wide by 18-20 inches deep. Always verify manufacturer specifications before cutting countertops. Wrong dimensions lead to expensive modifications or complete replacement.
Enclosed cabinets require ventilation to prevent dangerous gas accumulation. I insist on minimum 25 square inches of open vent area for enclosed installations. Safety should never be compromised for aesthetics.
Piezo ignition uses mechanical pressure to create sparks. Simple but prone to failure after 2-3 years of outdoor exposure.
Battery-powered electronic ignition provides more reliable sparking with the maintenance burden of periodic battery replacement.
Hot surface ignition offers the best reliability but requires electrical connection. Most common in premium models from established brands.
Proper installation ensures safe operation and optimal performance. I recommend professional installation for gas line connections due to safety risks and local code requirements.
Before starting, verify your countertop material can accommodate the required cutout. Natural stone and concrete countertops require specialized cutting tools. Many outdoor kitchen builders cut the opening before countertop installation.
Enclosed cabinet installations must include ventilation. I prefer passive vents at the bottom and top of the cabinet to create natural airflow through convection. This prevents gas accumulation and reduces corrosion risk.
Gas line connections should always include an accessible shut-off valve. This safety feature allows quick fuel isolation for maintenance or in case of emergency. Professional installers position the valve where it’s easily reachable but protected from accidental contact.
Test all connections with a soap solution after installation. Bubbles indicate leaks that require immediate attention before using the burner. Never rely on smell alone to detect gas leaks.
15,000 BTU represents the sweet spot for most outdoor cooking applications. This output boils water efficiently while maintaining low temperatures for gentle simmering. Heavy wok cooking benefits from 20,000+ BTU, while 12,000 BTU works for basic warming and light boiling.
Side burners transform outdoor cooking from grilling steaks to preparing complete meals outdoors. The ability to simmer sauces, boil vegetables, and keep sides warm while grilling eliminates constant indoor kitchen trips. For frequent outdoor entertainers, a quality side burner pays dividends in convenience and entertaining capability.
Most side burners offer conversion kits that allow switching between liquid propane and natural gas. The process involves replacing gas orifices and adjusting air mixture settings. While DIY-capable homeowners can complete conversion, professional installation ensures proper gas pressure and safe operation. Always use manufacturer-specific conversion kits.
Most side burners include standard cooking grates rather than flat griddle surfaces. Griddle accessories typically sell separately and are compatible across brands with standard burner dimensions. Some premium models offer integrated griddle options, but the majority of side burners use rod or cast iron grates designed for pots and pans.
Side burner cutout dimensions vary between manufacturers, though most fall within 12-14 inches wide by 18-20 inches deep. Always verify specific model measurements before cutting countertops. Standard dimensions exist but are not universal, and assuming compatibility can result in expensive modifications or complete replacement.
Side burners excel at sauce preparation, boiling vegetables and potatoes, stir-fry dishes, soups and stews, keeping sides warm, and searing with high-BTU models. The independent operation from your main grill allows complete meal preparation outdoors without running back and forth to indoor kitchen facilities.
After extensive research and analysis, the Livory Double Grilling Side Burner stands out as the best overall choice for serious outdoor kitchens. The 30,000 BTU combined output, independent burner controls, and included natural gas conversion kit provide unmatched versatility at a competitive price point.
Budget-conscious buyers should consider the VEVOR 15,000 BTU model for delivering 304 stainless steel construction at an accessible price point. The fuel convertible design adds flexibility for future outdoor kitchen upgrades.
For homeowners dedicated to natural gas with no need for conversion, the Stanbroil NG-only burner offers reliable performance without the complexity of convertible designs. Sometimes the best solution is the simplest one that matches your specific needs.
