If you've purchased a new Weber grill, the company says that seasoning the cast iron grates isn't necessary. A porcelain enamel coating is already added to the cast iron so you don't need to season it at all. Instead, they recommend that when using a grill for the first time, you turn up the heat for about 15 minutes, then brush it clean with a stainless steel bristle brush.
As for seasoning, most foods will taste great if you add just a little salt, pepper, and olive oil beforehand. That's the beauty of grilling: it's a fuss-free cooking method meant to elevate an ingredient's natural flavor without much elbow grease. That being said, if you want even more flavor, there are endless mouthwatering marinades you can add to your meat or veggies before they're barbecued. And if you're hosting a barbecue and need some simple summer sides, we've got tons here. Don't forget the rosé!
Inspect your burners for signs of corrosion or anything blocking the row of flame holes. Burner tubes are inviting spots for spiders to lay eggs if your grill goes unused for a while. Use a wire brush and clean them by brushing back and forth over the holes, not down the length of the tube. The wire bottle brush can clean out the inside of each tube.
Cast iron grill grates conduct heat quickly and evenly, cooking and searing meat for that distinctive charbroiled flavor. But to achieve those delicious results, cast iron grill grates need proper seasoning and regular care. Seasoning cast iron grill grates when they're new keeps your food from sticking and can prevent rust to make the grates last longer. Cooking on cast iron helps to create a smooth, non-stick surface to minimize seasoning needs in the future. Cast iron is porous, and as meat cooks, fats and oils soak into the pores where they harden.
Who's right? It's not that the notion of burning pepper is complete nonsense—in theory, yes, black pepper could burn. The problem with peppering midway through cooking is that the pepper granules might not stick to the meat. You could pass a pepper grinder at the table, but if you're cooking outside and eating in an informal style, this may not be feasible.
To season the grill, rinse the grill grate with plain water, then dry it thoroughly. The next step is to apply a fat – either vegetable oil or shortening – to the grates, coating all of the cast iron with it. Place the grill grate over a cold grill, then slowly increase the temperature to about 400 degrees and keep it there for about 40 minutes. Finally, allow the grill grate to cool.
