Gas Grill Griddle Combo Upgrade (Like a Pro) | Arteflame

Is it Possible to Convert a Gas Grill into a Griddle?

You do not need to purchase a standalone appliance to achieve professional flat-top results at home. By replacing your existing gas grill grates with a solid carbon steel insert, you instantly convert your current setup into a high-performance gas grill griddle combo. This upgrade captures virtually 100% of the burner heat, eliminates dangerous flare-ups, and allows you to cook smash burgers, steaks, and delicate vegetables simultaneously without increasing your patio footprint.

Which Griddle Material Performs Best on Gas Grills?

When upgrading your gas grill, the material of the insert dictates performance. While standard grates let heat escape and cast iron can be brittle, carbon steel offers the ideal balance of durability and heat conductivity.

Choosing carbon steel ensures that your gas grill griddle combo functions like a commercial kitchen flattop, seasoning better over time to become naturally non-stick.

Why Should You Upgrade to a Gas Grill Griddle Combo?

Most backyard chefs love the convenience of gas but miss out on the flavor profile provided by a solid surface. Standard grates allow juices to drip onto burners, causing flare-ups that char food rather than searing it. A solid insert creates a Maillard reaction across the entire surface of the meat, locking in flavor.

Pro Tip: Unlike cast iron, which is porous and can hold onto old rancid oils, carbon steel creates a patina that gets smoother with every cook. If you scratch a carbon steel insert, you can simply re-season it; you haven't ruined the coating.

Furthermore, a griddle insert makes your grill wind-resistant. Since the solid plate covers the burners, wind cannot blow out the flame, ensuring consistent cooking temperatures even in breezy conditions.

How Do You Install a Griddle Insert?

The process is incredibly simple and requires no tools. This ease of use is what makes the gas grill griddle combo such a popular upgrade.

1. Measure Your Space: Ensure you buy an insert that fits the width and depth of your specific grill model (e.g., Weber, Napoleon, or Broil King).
2. Remove Old Grates: Take out the wire or cast iron grates currently in your grill.
3. Clean the Firebox: Remove any debris from the burners to ensure even airflow.
4. Drop in the Insert: Place the carbon steel griddle directly onto the grate rests.

Once installed, light your burners. The steel will heat up rapidly. Because the air is trapped beneath the heavy steel plate, your grill will likely run hotter than usual, so you may need to adjust your burner knobs to a lower setting.

What Foods Cook Best on a Flat Top Insert?

The versatility of a gas grill griddle combo allows you to cook meals that are impossible on standard grates.

• Smash Burgers: You need a solid surface to press the beef down to get that crispy, caramelized crust.
• Breakfast: Eggs, bacon, and pancakes can be cooked directly on the grill without a skillet.
• Vegetables: Asparagus, onions, and peppers sear in their own juices rather than drying out or falling through the grates.
• Seafood: Delicate fish fillets and scallops sear perfectly without sticking or flaking apart.

Pro Tip: Use the "zone cooking" method. Turn one burner to high for searing steaks and another burner to low (or off) to keep sides warm. The solid steel conducts heat laterally, creating a natural temperature gradient.

Frequently Asked Questions

Will a griddle insert cause my gas grill to overheat?

Generally, no, but it does trap heat more efficiently than open grates. You should monitor the temperature gauge and likely use lower burner settings to maintain your desired cooking heat, which also saves propane.

Can I close the grill lid when using a griddle insert?

Yes, you can close the lid. However, because the insert retains significant heat, keep an eye on the internal temperature to prevent the firebox from getting too hot, especially with all burners on high.

How do I clean a carbon steel griddle insert?

Clean it exactly like a cast iron skillet. While the grill is still warm, scrape off food residue, wipe it down with a paper towel and a little oil, and let it cool. Never use soap, as it strips the seasoning.
