Grill with Side Burner Buying Guide

BTUs and Burner Count

BTUs measure heat output, but more isn’t always better. A 30,000 BTU main grill with 10,000 BTU side burner is sufficient for most tasks. Look for even heat distribution (e.g., Weber’s burner design) rather than raw power. Side burners should have a simmer setting, not just full blast. Three main burners are typical; four burners offer more zone control.

Build Quality and Materials

Porcelain-enameled lids and bodies resist rust and fading. Stainless steel burners last longer than aluminized steel. Cast iron grates hold heat but require seasoning; porcelain-coated cast iron is easier to maintain. Avoid thin gauge steel that can warp. Check for sturdy cart construction and wheels that roll smoothly.

Side Burner Practicality

Side burners vary from 8,000 to 15,000 BTUs. For simmering sauces, you need a burner that adjusts low. Some side burners have a dedicated cover; ensure it seals well to prevent debris. Also consider wind guards – some models have none, making the burner less effective in breezy conditions. Test the knob placement: it should be easy to reach without leaning over the grill.

Safety Notes

  • Always grill outdoors at least 10 feet from structures.
  • Check gas connections for leaks with soapy water after assembly.
  • Do not leave side burner unattended while lit.
  • Keep a fire extinguisher nearby and clean grease traps regularly.

What to Avoid

  • Grills with side burners that lack a simmer setting – they will burn sauces.
  • Thin steel grates that rust within a season – look for cast iron or porcelain-coated.
  • Models with reported ignition failures – check recent reviews for consistent spark.
  • Side burner covers that do not latch – they can blow off or warp.

FAQ

Can I use the side burner as a main cooking area?

Yes, but it’s smaller and less powerful. It’s best for sauces, sides, or boiling water.

How do I clean a side burner?

Remove burner cap and clean with a brush. Check ports for clogging. Wipe the housing with a damp cloth.

What size grill do I need for a family of 4?

A 400-500 sq in cooking area is sufficient. The Weber Spirit II E-310’s 424 sq in fits 12 burgers or 2 whole chickens.

Final Verdict

The Weber Spirit II E-310 is the best grill with side burner for most buyers, with consistent heat and a reliable side burner that simmers. For more space, the Char-Broil Performance 4-Burner is a solid value. Budget buyers can try the Royal Gourmet 4-Burner, but expect trade-offs in build quality.
