Upgrade your Prestige or Pro 500 series grill with a durable Grillflame cast-iron griddle engineered for even heat distribution and versatile cooking.

Which grill models does this griddle fit?

This replacement insert is made to fit multiple Napoleon Prestige 500 and Prestige Pro 500 variants as well as built-in RB editions. It aligns with original part numbers 56040 and 56041 used across several factory models.

• Compatible series: Prestige 500, Prestige Pro 500, built-in Prestige 500 RB and Pro RB models.

• Check your grill’s original part number (56040 or 56041) and the plate dimensions before purchasing.

How does the reversible design improve cooking options?

The two-sided cast-iron insert gives you both a flat griddle surface and a ribbed grill face so you can switch between styles without swapping tools. The smooth side is ideal for eggs, pancakes, and sandwiches, while the ridged side creates sear marks and channels away fat for proteins and vegetables.

• Smooth side for delicate foods and even browning.
• Ribbed side for searing, grill marks, and reduced contact with grease.
• 2-in-1 functionality reduces the need for extra cookware on the grill.

What are the material and performance benefits of this cast-iron plate?

Constructed from heavy, thickened cast iron, the Grillflame insert stores heat reliably and spreads it across the cooking surface for consistent results. When properly seasoned, the iron develops a natural nonstick patina that improves with regular use and care.

• Excellent heat retention for steady searing and uniform cooking.
• Durable, high-temperature tolerant cast iron for long service life.
• Becomes easier to clean and more nonstick after seasoning cycles.

How do I install and maintain this replacement griddle?

Installation is straightforward: remove your original insert and position the Grillflame plate in the same slot. Season the plate before first use and follow basic cast-iron care—clean with hot water, dry thoroughly, and apply a light oil coat to prevent rust.

• Confirm fit by comparing dimensions to your original plate (approx. 17 13/17" L x 13" W).
• Pre-season the griddle to build a protective cooking surface.
• After use, avoid soap; dry completely and lightly oil to preserve the seasoning.

Who is this for: Grillflame’s reversible cast-iron griddle insert is aimed at Prestige/Pro 500 owners who want a rugged, restaurant-style cooking surface that multiplies meal options on one burner slot. It’s ideal for backyard chefs who need a heavy-duty replacement plate that heats evenly and lets them switch between breakfast, searing, and casual grilling without extra pans. Verify compatibility with your exact Napoleon model and part number for a perfect fit before ordering.
