Upgrade Your Grill: Flat Top Combo (Easy) | Arteflame

The Best Way to Upgrade Your Kettle Grill to a Flat Top

You do not need to purchase a separate, bulky griddle to enjoy flat top cooking. By replacing your standard wire grate with a solid carbon steel insert, you can transform your existing kettle or Kamado-style grill into a high-performance flat top combo. This upgrade allows you to sear at temperatures exceeding 1,000°F while retaining the smoky flavor of charcoal, effectively giving you two grills in one footprint.

Why Convert Your Kettle Grill into a Flat Top Griddle?

Most backyard chefs struggle with a common dilemma: the need for flame-grilled flavor versus the versatility of a flat surface. Traditional wire grates let juice drip away, causing flare-ups and dry meat. A carbon steel flat top insert solves this by providing a solid cooking surface that prevents flare-ups while searing meat in its own juices.

Pro Tip: Unlike cast iron, carbon steel heats up faster and cools down more responsively. The more you cook on it, the better the seasoning becomes, eventually creating a slick, non-stick surface that rivals Teflon but handles extreme heat.

This conversion maximizes information gain for your cooking setup: you get the surface area of a griddle with the thermal power of a charcoal fire.

How Does the "Ring of Fire" Improve Grilling?

One of the distinct advantages of using a circular flat top insert on a kettle grill is the creation of distinct heat zones. Because the heat source is central or spread beneath the plate, the temperature varies naturally across the surface.

Mastering Dual-Zone Cooking

The center of the plate, closest to the charcoal, is your inferno zone. This is where you sear steaks to get that perfect crust. As you move toward the outer edges, the temperature drops slightly, creating a warming or slow-cook zone.

Pro Tip: Use the varying heat zones to cook a complete meal at once. Sear burgers in the center while simultaneously roasting asparagus or toasting buns on the cooler outer ring. Everything finishes at the same time without burning.

Which Foods Benefit Most from Flat Top Searing?

While wire grates are limited to large cuts of meat, a flat top combo opens up your menu options significantly.

• Steaks & Burgers: Instead of thin grill marks, you get a wall-to-wall sear (the Maillard reaction) which amplifies the savory umami flavor.
• Vegetables: Asparagus, onions, and peppers caramelize in their own natural sugars rather than drying out over open flames.
• Breakfast: You can easily cook bacon, eggs, and pancakes outdoors, keeping the grease and smoke out of your kitchen.
• Seafood: Delicate fish and scallops sear perfectly without sticking or falling through the grates.

Frequently Asked Questions

Can I use wood logs with a flat top insert?

Yes. Using hardwood logs adds a distinct smoky flavor that gas griddles cannot replicate. The carbon steel is durable enough to withstand the direct intense heat of a wood fire.

Does the insert require seasoning like cast iron?

Yes, seasoning is essential. You should coat the cooktop with a high-smoke-point oil (like grapeseed or canola) and heat it until it turns black. This creates the natural non-stick patina.

Will this fit my Weber or Green Egg grill?

Most flat top inserts are designed with specific dimensions to fit standard 18", 22", or 26" kettle grills and Kamado-style grills. Always measure your current grate diameter to ensure a drop-in fit.
