Grill Everything to Perfection with WEBER CONNECT Smart Technology

No one likes playing guessing games on the grill, and with the Weber GENESIS SPX-435 propane gas smart grill, you no longer have to! Integrated WEBER CONNECT smart technology provides real-time temperature alerts, reminders, and flip and serve notifications right at the grill or straight to your smartphone, keeping you dialed into your cook from anywhere. The result? Perfectly grilled food and satisfied friends and family every time, with no hassle or uncertainty along the way. In short, WEBER CONNECT is your secret ingredient for the best BBQs on the block, and a big reason why this model stands as one of the biggest grilling innovations in decades.

Integrated Lights, a Side Burner, & 4 High-Performance Main Burners

This top-of-the-line GENESIS grill has all the bells and whistles, or should we say lights and burners. A pair of integrated, motion-sensing LED lights in the lid handle illuminates the entire grill surface and side tables when activated, ensuring nighttime never runs you off the grill; remote control knob lights, meanwhile, enhance visibility in the dark and add a modern aesthetic. As for the burners, the Weber GENESIS SPX-435 smart grill includes a handy side burner for sauteing veggies, boiling sides, or heating up sauces while the main grilling area takes care of the heavy lifting. Those 4 main burners feature a proprietary, ported design to produce the most efficient and even flame for consistently precise heat and reliable ignition.

Upgraded Sear Zone, Prep & Serve Table, & More

Bigger and better in all the right places, the Weber GENESIS SPX-435 propane grill provides more usable space than ever. Your eye will likely be drawn to the extra-large sear zone, which also received an increase in BTUs to reach the next level of delicious caramelization for the whole party. The right-hand side table is similarly sized up, with enough space for multiple cutting boards or serving trays; this extra-large prep & serve table makes it easier than ever to create entire meals without having to leave the backyard. To help you accomplish that with even greater ease, the Weber GENESIS SPX-435 propane gas smart grill trades the usual warming rack for an expandable top cooking grate that functions as a secondary grilling surface when fully folded out. Oh, and the grease management system got a facelift as well: the removable drip pan is now attached to the grease tray for seamless cleanup, with an included scraper just for good measure.

The Ultimate Versatility of WEBER CRAFTED Grillware

At this point, it would be fair to wonder if there was anything the Weber GENESIS SPX-435 smart propane grill is incapable of doing. Well, we have some big news on that front: compatibility with WEBER CRAFTED Outdoor Kitchen Collection grillware allows you to cook food never thought possible on a gas grill. Roast, bake, sear, steam, and even stir-fry by simply replacing the standard grate with any of the custom-fit grillware! And with the Weber GENESIS SPX-435 propane gas smart grill, you are already one step closer to the full backyard culinary experience thanks to the frame kit being built in (though the grillware itself is sold separately). This grill also includes a storage locker to keep your WEBER CRAFTED accessories, as well as certain large grilling tools, safe from the elements and close at hand.

    For someone who loves experimenting with different cuts and techniques, this grill delivers reliability every time. The extra cooking space makes hosting friends effortless, and the controls are intuitive even for longer cooks. It feels like a premium outdoor appliance rather than just a grill.

    Nationwide delivery was faster than expected and the whole buying process was smooth thanks to responsive customer service.

  3. Theda

    Excellent grill for both weeknight dinners and weekend barbecues. The burners are powerful, and the smart tech takes out the guesswork. Definitely worth it.

  4. Mabel

    I’m very happy with this purchase. It heats up quickly, holds temperature well, and the cooking space is generous enough to handle big family gatherings. The controls are smooth, and I love how sturdy it feels.

  5. Burl

    Perfect for family cookouts—fast, efficient, and reliable.

  6. Virgil

    Solid build, great heat control, and a joy to cook on.

  7. Lowell

    This grill has completely upgraded my outdoor cooking setup. The heat is even across the surface, so I don’t have to worry about hot or cold spots. The smart features are a big plus—I can monitor the temperature right from my phone and never have to lift the lid unnecessarily. Build quality is top-notch, heavy-duty but still sleek, and it feels like it will last for many years. Cleaning is straightforward with the removable trays, and the burners fire up instantly every time. I’ve already hosted two cookouts and everyone was impressed with how well it performed.
