Our full review

The Broil King Regal S590 Pro stands as a flagship gas grill designed for serious backyard chefs who demand both power and precision. Constructed with a durable stainless steel body, this grill combines rugged good looks with long-lasting performance, standing up to the elements year after year. Its five main stainless steel burners deliver a combined output that provides even, consistent heat across the expansive cooking surface, while the dual-tube burner design ensures reliable ignition and steady flame distribution. The heavy-gauge stainless steel construction extends to the lid and cabinet, giving the grill a commercial-grade feel that signals quality craftsmanship at every glance. At the heart of the Regal S590 Pro's cooking system is Broil King's signature Flav-R-Wave cooking system, which vaporizes drippings to infuse food with rich, smoky flavor while minimizing flare-ups. The cast stainless steel cooking grids retain heat exceptionally well and create those coveted sear marks on steaks, burgers, and vegetables alike. An integrated rear rotisserie burner with a heavy-duty rotisserie kit allows for slow-roasted perfection on whole chickens or roasts, expanding the versatility of this grill well beyond basic grilling. A side burner adds further functionality, letting users simmer sauces or sear sides without needing to step away from the main cooking area, making this unit a true outdoor kitchen centerpiece. Practical details round out the Regal S590 Pro's appeal, including a spacious main cooking area complemented by a warming rack, giving ample room to prepare full meals for family gatherings or larger parties. The cart-style design features cabinet storage with towel bars and integrated tool hooks, keeping grilling accessories organized and within reach. Convenient side shelves offer extra prep space, while the built-in temperature gauge on the lid allows for easy monitoring without lifting the hood. Smooth-rolling caster wheels make repositioning simple, and the overall build quality reflects Broil King's reputation for producing grills that perform reliably season after season, making the Regal S590 Pro a worthwhile investment for anyone serious about elevating their outdoor cooking experience.

Best grill I've owned — Mark T. (2024-05-12)
The Growl Grates are a game changer for steaks. Even heat across the whole surface and the smoker box actually works well for ribs.
Great grill, tough to assemble — Denise R. (2024-03-28)
Performance is fantastic once set up, but building this thing took my husband and me almost 4 hours. Worth it in the end.
Rotisserie kit is a nice bonus — Chris P. (2024-06-02)
Used the rotisserie for a whole chicken and it came out perfect. Build quality feels very solid and premium.
Pricey but reliable — Angela S. (2024-04-15)
Definitely an investment but the dual-tube burners heat up fast and hold temperature well even in windy conditions.
