When it comes to grilling, many enthusiasts focus on fuel type, BTUs, or smoker boxes—but one of the most important and often overlooked components is the grilling surface itself. The material you grill on affects heat retention, cooking style, flavor, and even maintenance. Let’s break down four popular grill surface options: stainless steel grates, porcelain-coated enamel grates, Island Grillstone, and flat-top griddles.
Stainless Steel Grates: Durable and Low Maintenance
Stainless steel grates are a staple in many gas. They’re rust-resistant, easy to clean, and can withstand years of use. One major benefit of stainless steel is its durability—it won’t chip or crack over time. It also heats up relatively quickly and offers decent heat retention.
However, stainless steel doesn’t sear quite as well as cast iron. Thick, solid grates (not stainless wrapped) can help improve the heat retention and searing capability of the stainless grates.
Porcelain-Coated Enamel Grates: Nonstick with a Catch
Porcelain-coated grates are usually made from cast iron or steel and coated in a glossy enamel. The coating helps prevent rust and makes the grates easier to clean. The underlying cast iron offers excellent heat retention, making these grates great for searing.
However, there’s a trade-off: the porcelain coating can chip or crack if you’re not careful—especially when using metal tools or dropping them. Once the coating is compromised, rust can set in.
Island Grillstone: Healthier and More Even Cooking
The Island Grillstone is a natural stone grilling surface, typically made from volcanic rock. Unlike metal grates, it doesn’t allow food to come in contact with open flame, which reduces flare-ups and prevents charring. It’s ideal for health-conscious grillers who want to avoid burning or losing food through the grates.
The Grillstone provides even, gentle heat, making it perfect for fish, vegetables, and delicate proteins. However, it takes longer to heat up and isn’t meant for quick searing or high-temperature cooking.
Griddle: Versatile and Great for Breakfast or Smash Burgers
Griddles offer a flat, solid cooking surface that excels at evenly cooking small or delicate items—think eggs, pancakes, bacon, or smash burgers. Usually made of steel or cast iron, griddles retain heat extremely well and offer a different kind of grilling experience.
They lack the grill marks and charbroil style that grates provide, griddles shine in versatility. You can cook an entire meal without losing a single mushroom slice through the grate. Just keep in mind: they require more cleanup and can be heavy.
Final Thoughts
Your grilling surface can seriously impact your cooking results. The best grill surface depends on what—and how—you like to cook. Consider mixing and matching surfaces if your grill allows for it, so you can enjoy the best of all worlds.
