The Best Outdoor Grills You Can Find At Costco

Grilling season is right around the corner, and for many of us, that means uncovering the old grill and giving it a good once-over before firing it up. Others, however, might be seeing tell-tale signs that it's time to replace their grill, or perhaps they're purchasing one for the first time. The off-season can be the best time to purchase a new grill, and while you can find them at a wide number of retailers, Costco has reasonable prices on some of the best outdoor grills.

These grills come with a variety of options, and choosing the right model will require thoughtful consideration of how each aligns with your needs. Costco has several outdoor grills that are highly rated by consumers; the Traeger Mesa Pellet Grill, the Weber Genesis II S-435 Gas Grill, and the Kirkland Signature Stone Island 12-burner Gas Grill are among the top options. Each has unique specifications that allow you to grill your favorite foods with plenty of available features.

We chose these grills for their many positive reviews  — being well over 4-stars based on reviews — where customers praise features like the grills' performance, ease of use, quality of build, and striking appearance. While the products mentioned vary in affordability, they consistently deliver on quality and performance, thus earning them a place in this lineup. If you're in the market for a new grill, any of these three could be ideal for turning your grill station into the perfect entertaining space.

Beginning with the most budget-friendly and basic model, Costco has the Traeger Mesa Pellet Grill, which retails for $599.99. This grill is, as the name suggests, heated with pellets, which affords the grill master with consistent grilling temperatures. Along with the seamless temperature regulation, you'll get 520 square inches of grilling space, and a versatile grilling companion that allows for smoking, baking, roasting, braising, and churning out some tasty BBQ.

Out of over 100 customer reviews, nearly 80% have given this pellet grill a 5-star rating. This grill earns a place on a list of best grills at Costco due to the combination of it being quite affordable and yet remaining impressive in terms of performance and customer feedback. Owners of the grill are appreciative of how easy it is to use, and they got some great-tasting food from it. Several reviews mention that the grill is a bit on the small side, making it suitable for individuals or couples, but maybe too tiny for larger families or friend groups. One positive customer review states, "Very impressive. Smoked a brisket for about 15 hours and got the best smoke ring I've ever gotten. It was a hit. Very easy to operate and shutdown." While there is a lot to love about the Traeger Mesa Pellet Grill, there is a portion of buyers who are critical of the device, saying that it doesn't get sufficiently hot and that it wasn't reliable in its performance. 

If you're a purist who wants to see those iconic grill marks on your food, you might opt for the Weber Genesis II S-435 Gas Grill, which goes for $1,349.99. This traditional gas grill is equipped with stainless steel rod cooking grates, which are designed to offer a superior cooking surface that retains heat well. There's also a searing station to lock in the juices and flavors of your meat. Since Weber is renowned for its excellent brand reputation, you can open your wallet with some serious peace of mind, which is much-needed when making a purchase of this scale. In addition to its bells and whistles, the Weber Genesis comes with a 10-year limited warranty to protect you against product issues.

The Weber Genesis earns itself a spot on this lineup thanks to over 400 reviews, where approximately 83% of reviewers gave it a five-star approval rating. One customer writes, "This grill does it all. I can actually light it without fear of losing all my hair! The grill cooks beautifully and is a pleasure to use. When we are done, it also cools off quickly so we can cover it back up before we forget!" Features that make this grill worth purchasing include the quality of materials, as many customers note that the metal seems heavy-duty, and how easy it is to light when ready to use. Although this is one of the best grills at Costco, many reviews do mention difficulty or frustration with the paid installation service from the wholesale club; because of this, it's important to find a reputable installer to ensure that your grill is assembled properly and professionally. 

If you consider yourself a serious grill master who's in the market for a significant upgrade, you might want to look into the Kirkland Signature Stone Island 12-Burner Gas Grill, which has a price tag of $3,499.99. With a total of 1,220 square inches of cooking space and 118,000 BTUs, you won't want for power when firing up this grill — and it comes loaded with features such as LED lighting, searing and griddle stations, and foldable side shelves.

For such a big purchase, you'll want to know that your money is well spent. We chose this grill from Costco based on the fact that 72% of reviewers gave it five stars, noting its pleasing aesthetic and performance. One very positive review states, "This is perfect for me as a chef who has always wanted a backyard kitchen. While doing the research, I found this grill online and realized I could get the same quality for a fraction of the price. I can cook, grill and sear all in one unit which is pretty amazing! It's not only beautiful to look at, but setup is easy." 

Despite the grill being a solid choice when everything is functioning well, multiple reviews raise red flags about missing parts, which can create a real hassle if you are planning on using it shortly after purchase. In order to avoid any grill-related headaches, it can be wise to carefully review you product's assembly instructions during installation and immediately contact customer service about any discrepancies. No matter what grill you choose, remember to keep it spic and span with the best grill cleaners this summer.
