Adviace Cast Iron Reversible Griddle for Napoleon Grills, 13 x 17.75 in, Flat & Ribbed Heavy-Duty

Adviace's cast iron reversible griddle is a heavy-duty 13" x 17.75" replacement plate that converts compatible Napoleon grills into a flat griddle or ribbed grill for searing, breakfast, and high-heat grilling.

If you own a Napoleon Prestige, Prestige Pro, Built-in Prestige, Phantom Prestige, or LEX series grill listed below, this Adviace 56041/56040 reversible cast-iron griddle provides a robust, two-sided cooking surface built to fit and perform like the original. Made from thick cast iron (about 11.8 lb), the plate delivers strong heat retention, even cooking across the 33 x 45.1 cm surface, and a reversible design with one flat side and one ribbed side for versatile backyard cooking.

Which Napoleon grills will this Adviace griddle fit?

This plate is made as a replacement for many Napoleon models in the Prestige, Prestige Pro, Built-in Prestige, Phantom Prestige, and LEX families. Check your grill model number against the compatibility list before ordering to ensure a proper fit.

• Prestige 500 series (e.g., P500PSS-3, P500NSS-3) and Prestige 500 RSIB variants
• Prestige Pro 500 and 665 RSIB models, Prestige 665 and PRO 825 variants
• Built-in and Legacy Prestige 500, Phantom Prestige 500 Connected models
• LEX series including 485, 605 and 730 model families

How does the two-sided design change what I can cook?

The reversible griddle gives you a flat cooking plane for eggs, pancakes, and smashed burgers, plus a ribbed surface that creates sear marks and channels juices. Flip the plate for a griddle-style breakfast or a ridged sear for steaks and vegetables without changing cookware.

• Flat side: ideal for delicate foods, even browning, and pan-style cooking
• Ribbed side: creates caramelization, grill marks, and reduces contact with grease
• Use both sides to expand menu options on one grill—breakfast to dinner easily

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

Constructed from heavy cast iron, the Adviace griddle stores and distributes heat evenly across its surface so foods cook consistently. The dense metal keeps temperatures stable under high heat, which helps with searing and maintaining even browning.

• Approximately 11.8 lb heavy cast iron for thermal density and retention
• Even heat distribution reduces hot spots for more predictable results
• Durable integrated molding resists warping under repeated heating cycles

How do I prepare and care for the cast-iron griddle to get a nonstick surface?

Seasoning builds a protective, naturally nonstick layer and helps preserve the griddle. Simple cleaning, oiling, and heating steps create the seasoned surface that improves with use.

• Clean with water and a soft sponge, then dry thoroughly before seasoning
• Brush with vegetable oil and heat (oven or grill) to polymerize the oil into seasoning
• After seasoning, store dry to prevent rust and re-season as needed over time

Who this griddle is for: home grillers who want a heavy-duty aftermarket replacement to expand what their Napoleon grill can do. Ideal for people who cook a variety of foods—breakfast, burgers, vegetables, and delicate items—that benefit from a flat surface or ribbed searing. Also suited to owners of the supported Prestige and LEX models who need a durable, reversible cast-iron plate that matches the grill’s footprint and delivers consistent heat.
