Buyer’s Guide: What to Consider
Choosing the right griddle cooktop insert depends on your grill type, cooking needs, and maintenance preferences. Here are five key factors to consider before making a purchase.
- Material: Cast iron offers superior heat retention and durability but requires seasoning and is heavy. Stainless steel is lighter, rust-resistant, and easy to clean, but may not hold heat as well. Carbon steel balances weight and heat retention, often with nonstick coatings.
- Size and Fit: Measure your grill or stovetop before purchasing. Griddles come in various sizes, from compact 17-inch models to full-size 25-inch inserts. Ensure the griddle fits your specific grill model or stove burner configuration to avoid gaps or overhang.
- Nonstick Coating: Some griddles come pre-seasoned with vegetable oil, while others feature ceramic or nano-ceramic coatings for enhanced nonstick performance. Consider how much maintenance you are willing to do—seasoned cast iron requires regular upkeep, while coated options are easier to clean.
- Heat Distribution: Look for griddles with designs that promote even heating, such as wavy undersides or thick materials. Even heat distribution prevents hot spots, ensuring your food cooks uniformly. Cast iron and carbon steel generally provide better heat retention than stainless steel.
- Ease of Cleaning: Raised sides help contain grease and food, making cleanup easier. Detachable handles allow for efficient storage and stacking. Nonstick surfaces reduce scrubbing time. Consider whether the griddle is dishwasher safe or requires hand washing.
Conclusion
Griddle cooktop inserts are a fantastic way to expand your cooking capabilities without buying a new appliance. Whether you prefer the classic heat retention of cast iron, the convenience of nonstick coatings, or the lightweight nature of stainless steel, there is an option for every griller.
For most outdoor cooks, the Uniflasy cast iron griddle offers excellent value and performance, while the Charbroil insert is perfect for quick conversions. If you own a Nexgrill, the LS’BABQ or EasiBBQ inserts are tailored to fit perfectly. Consider your specific needs and choose the griddle that best matches your cooking style.
