The Full Review

The Weber Genesis SX-335 Smart Grill stands as a premium gas grill built for those who want restaurant-quality searing power paired with modern connected cooking technology. At the heart of this grill are its signature stainless steel burners, three of them, delivering a combined 39,000 BTUs of consistent heat across the cooking surface. What truly sets the SX-335 apart within Weber's lineup is the infrared sear burner, which reaches extreme temperatures ideal for locking in juices on steaks, chops, and other proteins that demand a professional-grade crust. The grill runs on either liquid propane or natural gas depending on the configuration chosen, and its stainless steel cooking grates provide excellent heat retention while remaining easy to clean after heavy use. Smart functionality is woven directly into the SX-335 through Weber Connect, a built-in system that pairs with the Weber app to guide home cooks through every stage of a meal. The integrated meat probe monitors internal temperature in real time, sending alerts to a smartphone when it's time to flip, baste, or pull food off the grate, effectively removing the guesswork that intimidates less experienced grillers.

This connected approach doesn't sacrifice the tactile grilling experience; rather it enhances it by layering data-driven precision over Weber's proven burner and grate design. The grill's total cooking area comfortably accommodates large gatherings, offering enough primary grates to handle multiple racks of ribs, a dozen burgers, or a full spread of vegetables and proteins simultaneously, while the warming rack keeps side dishes or buns at the perfect temperature without added heat exposure. Built with durability and everyday usability in mind, the Genesis SX-335 features a sturdy stainless steel and powder-coated cart frame designed to withstand years of outdoor exposure, along with enclosed cabinet storage for propane tanks or grilling tools. The side tables offer generous prep space, and integrated tool hooks keep spatulas and tongs within easy reach during cooking sessions. An electronic ignition system ensures reliable startup every time, while the grill's overall footprint strikes a balance between compact patio placement and expansive cooking capability. For grill enthusiasts who want the reliability of a Weber gas grill combined with smart monitoring convenience, the Genesis SX-335 delivers a well-rounded, technologically enhanced outdoor cooking experience suited for both weeknight dinners and weekend cookouts alike.
