Which Side Faces Up On A Cast Iron Grate?

Which Side Faces Up On A Cast Iron Grate?

A frequently asked question from our Facebook and Twitter fans is which side of the cast iron grates should be facing up when grilling? This question would apply to fans that have a Genesis or Spirit series gas grill. 

The wider, flat side of the cooking grates should be facing upwards for cast iron grates.  The underside is more pointed like the top of a triangle. There are four small legs in each corner on the underside of the grate to ensure a level cooking surface.  This will help stabilize the food.  Additionally, the wider, flat side of the grates will be easier to clean after grilling.

Happy grilling!

Great to see you took our advice and made the cast iron grates reversible. Was admiring the new 2017 Genesis grills and noticed that the pointed side has been changed so the cross ties are no longer raised. Great idea!

My thinking was the flat side up was for better searing because it is wider and the v shape was to let the juices drip down to get a good flavor in the smoke ounce it hits the flavor bars. Just sayin

How do I know if my New Genesis 310 has a porcelain coating on the cast iron grates? Thanks Frank

Hi Frank! That's an easy one, all of our cast iron grates are coated in porcelain-enameled. - Alycia

I've cooked with the grates facing both ways and get good results either way.
For fish, I prefer the grates flat side up, while for chicken or steaks prefer the grates pointy side up for more defined grill marks.
Overall, I definitely prefer the cast iron grates on my mocha brown Gensis at home over the round stainless grates we have on our stainless Genesis we use at our family ranch in Central Texas.
Happy grilling to all!

Glad I found this blog. I bought a Spirit 210 last year and was puzzled as to which side the grates should be installed. After inspecting them a bit, it seemed like the flat side made sense since the cross ridges on the underside would make turning over food with a spatula difficult.

As a graphic designer...here's a simple solution. Consider adding an illustration closeup to the assembly instructions showing the "correct" direction of the grates.

Great grill by the way!

I prefer the pointed side up as well. I am purchasing a new SS Genesis this week and swapping out the grates as I prefer cast iron. The only problem I see is that the cross ties on the bottom side protrude above the other gates. That would be a problem. Maybe you'll consider making both sides of the grates flush so they could be used either way. The wide sear marks are my only complaint so far.

I have a Genesis 330 with a sear station. Typically I leave 1 grate points up on the sear station side and the other flat side up. I use the pointed side up for food that you turn with tongs, and the flat side for food you turn with a spatula (like burgers).

"There are four small legs in each corner on the underside of the grate to ensure a level cooking surface. This will help stabilize the food. Additionally, the wider, flat side of the grates will be easier to clean after grilling."

Grill should be level either way as long as it was manufactured correctly, assembled correctly on on a level surface. Why does the food need to be stabilized? And as far as the wide flat surface for cleaning, all Weber cleaning brushes appear to be capable of cleaning the V shaped side just fine. I really don't get the advice to have the flat side up. Can't see that it will make the food taste better or make the food cook slower or faster. I've been cooking pointy side up for years. Cheers!

Hi James! Having the grates flat side up is how they were designed and tested but we appreciate your feedback and will definitely take it into consideration. Thanks for being a Weber fan and grill on!

Glad I found this blog. I, too, have been grilling on my brand new Weber S-210 with the grates installed upside down. As others have mentioned, I think I'm going to keep doing it that way - the grill marks look better than with the grates flat side up. My original reason for checking out the blog was to find out about seasoning the grates - no details in the manual, and when I called the rep wasn't very helpful, I didn't get a clear answer. It is using the porcelain enameled cast iron cooking grates (according to all advertising) and I discovered some surface rust the last time I went to use it. I didn't think that you'd need to season the type of grates that I have, and the rep on the phone seemed to confirm this, yet I'm seeing no details online about that particular type of grate.

Hi Brent! Your porcelain-enameled cast iron cooking grates do not need to be seasoned. Simply preheat your grill with all burners on high for 12-15 minutes, brush the grates clean with a stainless steel bristle brush, adjust the burners to your desired cooking temperature, and you are good to grill!

Hi! A quick question from a happy griller from the Netherlands.

Is it correct that pre-heating takes longer when cast iron grates are installed? I recently replaced my regular grates for cast iron (combined with the spring cleaning) and pre-heating takes quite a bit longer now. (Still reaches 300 degrees celcius)

Hi Remco! We recommend preheating all of our grates for 10-15 minutes regardless of which material they're made of. Thanks and grill on! - Jennie
