Upgrade Your Weber Spirit (Griddle Insert) | Arteflame

Can I Convert My Weber Spirit Into a Griddle?

Yes, absolutely. You can instantly transform your Weber Spirit II 200 or 300 series gas grill into a high-performance flat-top griddle by replacing the stock wire grates with an Arteflame carbon steel insert. This upgrade eliminates dangerous flare-ups, allows for restaurant-quality searing, and enables you to cook versatile foods like smash burgers, eggs, and vegetables that would normally fall through standard grill grates.

How Does the Arteflame Insert Compare to Standard Weber Grates?

Before diving into the setup, it is crucial to understand the performance difference. The table below highlights why switching to a solid carbon steel surface creates a superior cooking environment for most outdoor meals.

Replacing your grates changes the thermodynamics of your grill. Instead of hot air drying out your food, the solid steel transfers heat directly, locking in juices for a better flavor profile.

Why Should I Upgrade My Weber Spirit to a Flat Top?

Is the Searing Really Better?

Standard grates sear only where the metal touches the meat. The Arteflame insert provides 100% surface contact. This maximizes the Maillard reaction—the chemical process that creates that savory, brown crust on high-end steakhouse chops and smash burgers. Because the carbon steel retains heat exceptionally well, you get a consistent sear without cooling down the surface when you drop the meat.

What About Flavor and Flare-Ups?

One of the biggest frustrations with gas grilling is flare-ups burning the food. Because the Arteflame insert is solid, grease never drips directly onto the burners. Instead, the juices sizzle on the hot steel, vaporizing back into the food to enhance flavor.

Pro Tip: Look for the "Smoke Point." When your oil just begins to smoke lightly, the carbon steel is at the perfect temperature for searing steaks or smashing burgers. Do not overheat empty steel for long periods without oil.

How Do I Install and Maintain the Insert?

Is Installation Difficult?

No tools are required. The process takes less than a minute:

1. Remove the existing wire or cast iron grates from your Weber Spirit.
2. Drop the Arteflame carbon steel insert directly into the grill body.
3. Light your burners and allow the steel to heat up.

The insert is precision-cut to fit Weber Spirit II 200 and 300 series models perfectly, ensuring no wobble and optimal heat distribution.

How Do I Season the Griddle?

Carbon steel behaves like premium cast iron cookware. It requires seasoning to become non-stick and rust-resistant.

• Step 1: Heat the grill insert.
• Step 2: Apply a thin layer of cooking oil (grapeseed or canola work best).
• Step 3: Let it cook until the oil polymerizes (turns black).
• Step 4: Repeat. The surface will get darker and more non-stick with every cook.

Pro Tip: Never wash your carbon steel insert with soap. Soap strips the seasoning. simply scrape it clean while warm, wipe it with a paper towel, and apply a light coat of oil to protect it until the next cook.

Frequently Asked Questions

Will the Arteflame insert rust if left outside?

If left unseasoned and exposed to moisture, carbon steel can develop surface rust. However, if you keep it well-oiled and seasoned (just like a cast iron skillet), it is incredibly durable and weather-resistant. Use the grill lid to protect it when not in use.

Does the insert use more propane than standard grates?

The insert may take slightly longer to reach initial searing temperature compared to thin wire grates because of its thermal mass. However, once hot, it retains heat much more efficiently, allowing you to potentially lower the burner settings during the cook.

Can I use metal spatulas on the insert?

Yes. Unlike Teflon or non-stick coated pans, carbon steel is tough. You can use heavy-duty metal spatulas, scrapers, and tongs without worrying about scratching or damaging the cooking surface.
