Updated 25″ x 16″ Cast Iron Griddle For Outdoor Grills
The QuliMetal griddle top is designed for universal compatibility, measuring 25″ by 16″. It fits Weber Genesis, Charbroil, Nexgrill, and about 90% of common gas or charcoal grills. Its nano-ceramic coating resists scratches and provides even heat distribution to minimize hot spots. A built-in grease trough helps manage drippings, reducing flare-ups and simplifying cleanup. This model excels for eggs, pancakes, vegetables, and delicate proteins, while standing up to frequent outdoor use.
Weber Rust-Resistant Outdoor Griddle Insert
This Weber insert is crafted for Spirit 4-burner grills (since 2025), Spirit/Spirit II 3-burner grills (2016–2025), and Searwood pellet grills. It transforms the entire grill surface into a full-sized griddle with pre-seasoned readiness. The large cooking area supports family-style meals and batch cooking, while the pre-seasoned finish saves time before first use. It is especially suitable for breakfast, lunch, and dinner preparations requiring steady, high-heat management.
Griddle For Gas Grill 17″ x 13″ With Nonstick
The Uniflasy 17″ x 13″ griddle offers universal compatibility with many popular brands, including Weber, Nexgrill, Charbroil, and Camp Chef. Its heavy-duty metal construction features a nonstick coating for easy food release and simple cleanup. High sidewalls and ventilation holes help prevent grease spills and promote even heat distribution, making it versatile for everything from breakfast items to sautéed vegetables and burgers. A practical handle design supports easy repositioning during cooking.
Cast Iron Griddle With Nanoceramic Coating
This Uniflasy cast iron griddle uses an advanced nano-ceramic coating to combine scratch resistance with strong nonstick performance. The 17″ x 13″ plate is designed to fit many gas and charcoal grills, including Weber and Nexgrill. The coating distributes heat evenly to prevent hot spots, and high bars along the sides minimize splashes. Compatibility guidance emphasizes checking grill dimensions before ordering to ensure a precise fit for optimal cooking results.
Bull Outlaw 30-Inch Built-In Grill (Gas)
The Bull Outlaw model is a built-in gas grill that emphasizes high performance with 60,000 BTUs total from four welded stainless-steel burners. Its 304 stainless steel construction ensures durability and heat retention, while the single-piece dual-lined hood helps maintain consistent temperatures.

Weber Rust-Resistant Griddle Insert For Genesis And Summit
This Weber insert is designed to fit Genesis and Summit gas grills (Genesis 2016+ and Summit 2025+). It converts the grilling surface into a full-sized griddle, providing abundant space for multiple dishes at once. Pre-seasoned and ready to use out of the box, it offers convenience for quick setup and immediate cooking, especially for family breakfasts, stir-fry, and seared items that benefit from steady, flat heat distribution.

The design also highlights easy handling for shifting the griddle during meal prep and clean-up.
Buying Guide: Key Considerations For Choosing Gas Grill Inserts
- Fit and compatibility: Check your grill model and dimensions to ensure a snug, stable fit. Universal griddles offer broad compatibility but may require precise measurement.
- Material and durability: Nano-ceramic coatings provide scratch resistance and nonstick performance, while cast iron offers superb heat retention but requires seasoning and maintenance.
- Heat distribution: Even heat prevents hot spots. Look for coatings or design features (ventilation, sidewalls, and weight) that promote uniform cooking.
- Cleaning and maintenance: Nonstick surfaces simplify cleanup; grease troughs or channeling help manage drippings and reduce flare-ups.
- Size and cooking area: Larger griddles enable family-style cooking, but ensure you can safely handle them on your grill without crowding burners.
- Installation and handling: Some inserts are designed for built-in grills, while others are portable. Consider handles, weight, and ease of placement.
- Versatility: Look for surfaces suitable for breakfast, lunch, and dinner items—pancakes, eggs, vegetables, seafood, and meat all benefit from flat-top griddles.
To maximize outdoor grilling results, pair a high-quality insert with proper heat control and maintenance routines. Preheat before cooking, oil the surface lightly, and practice safe handling to extend the life of your insert. Consider your typical meals, space, and grill type when selecting the best option for your outdoor kitchen.
