Oh -- you can't? Mostly mine just have veggies and EVOO. Burn it clean, and ready to go. But sometimes they have to be cleaned -- ugh!I don't use them, but I do think they could be useful at times. But, kinda like Rich, probably not a Gotta Have It and one big problem I have with them is that they have to be cleaned up when done. Can't just heat 'em up and scrape them off.
Emory, the Weber 6435 might fit the bill. It is 17.5” X 12”. It is easier to use with a spatula because of the lower sides. I don’t use it as much as the deeper sided ones but it has it’s uses from time to time.Someone mentioned a grill basket set from Costco. I looked online and saw a set of two grill baskets on sale at Costco's website for $15.99 (reg. $19.99). They were NOT the ones pictured in this thread. They had flat beds and angled sides with wide gaps at the corners. I almost pulled the trigger on them, until I saw enough negative reviews that mentioned thin steel, lightweight, "foil is better", warping, "twisted like pretzels" and such.
What I think I want is a basket that has a fairly large flat surface with small holes or slits. Most of the baskets seem too small to spread out multiple thin onion slices to grill and slightly char. I have also ruled out the baskets with the round holes that look like notebook paper holes. I think that we might lose some of the onions and other foods through those larger holes. Slits or tiny holes would be better, I believe.
We could spend the money for the Weber Crafted Roasting Basket, which is large and flat and has the right slits, but it costs $110. The price is more than I care to pay for a grill basket, and the size is too large for our needs.
I'll keep looking until I find the right basket, thank you.
