Patented Oval Design

The unique oval shape offers exceptional cooking efficiency and true two-zone cooking. Two distinct cooking zones allows you to grill and roast simultaneously. Round ceramic grill companies can make the claim, but Primo is the only one that delivers.

Grill, Bake, Roast, or Smoke All on the Same “Grill”

Primo ceramic grills work like a grill, an oven, a roaster, and a smoker. Simply choose a cooking configuration to meet your needs and cook any recipe...from steaks to bread to beef brisket.

Primo Offers Amazing Flavor

The combination of the ceramic shell and 100% natural lump charcoal creates juicier food and true wood-fired flavor. Enjoy mouthwatering and delicious food that gas and metal grills just can’t offer.

Made in USA

4 out of 5 Americans prefer products made in the USA*, so it’s easy to see why Primo is one of the most popular grills over its imported counterparts.
