If you are building or refining an outdoor kitchen, you want to know which approach gives you better heat, better sear marks, and less hassle for the way you actually cook.

- Tight grate gaps ideal for small foods that often fall through wire grates
- Praised by users for solid fit, easy cleaning and non-stick performance when seasoned

The Quantfire 13 Inch Cast Iron Cooking Grid is a round replacement grate designed specifically for Small and MiniMax Big Green Egg charcoal grills and other 13 inch round cookers. It is ideal for Egg owners who want a more substantial, heat retentive cooking surface than standard wire grates.
In real world use, the cast iron excels at fast, even heat conduction and superior heat retention. Users report excellent searing, attractive grill marks and no sticking when properly seasoned, while the tight bar spacing keeps smaller foods like vegetables from falling through.
Build quality is a clear highlight, with thick, heavy cast iron bars and solid round construction that feels built to last. At 2.25 kg, the grate has reassuring heft and distributes heat uniformly to help preserve seasoning and smoky flavors.
There are a few considerations to keep in mind. Cast iron requires routine care, including oiling before first use and after cleaning to prevent rust. The 13 inch diameter is also size specific, so you must measure carefully as it runs slightly smaller than some 13.75 inch grates.
Overall, this is a heavy duty, well made upgrade that delivers pro level searing and impressive durability. If you own a Small or MiniMax Big Green Egg and want better heat performance and longevity, this Quantfire grate is an excellent choice.

Weight: 2.25 kg
Max Temperature: 500C
Compatibility: Small and MiniMax Big Green Egg and other same size charcoal grills
Use: Main cooking surface for grilling and smoking
Before first use, apply a thin layer of cooking oil to the entire surface and let it sit to season the cast iron. This helps create a natural non-stick surface and protects against rust.
After each cook, clean the grate while warm, dry thoroughly and apply a light coat of oil before storing. Avoid prolonged moisture exposure and store in a dry place to prevent rust.
Always measure your grill's internal diameter before purchasing to confirm fit. This grate is designed for 13 inch openings and may be slightly smaller than some original grates, so check your model carefully.
Pros
- Outstanding heat retention and searing from thick, pre seasoned cast iron
- Extremely durable heirloom build quality, made in the USA
- Precise temperature control with dual adjustable air vents
- Compact yet spacious enough for burgers, steaks and vegetables
- PFAS free, non toxic finish that is easy to clean and maintain

The Lodge Sportsman's Pro Cast Iron Grill is a compact charcoal hibachi style grill designed for outdoor enthusiasts who value performance over portability gimmicks. Measuring 9 by 16.75 inches, it is perfect for campers, tailgaters, apartment dwellers and anyone who wants authentic charcoal flavor in a small footprint.
In real world use, the thick cast iron delivers impressive heat retention and even cooking, producing beautiful sear marks on steaks, burgers and vegetables. Dual adjustable air vents give you responsive control over temperature, while the removable grate makes it easy to add charcoal or adjust heat without interrupting your cook.
Build quality is where this grill truly stands out. Made in the USA from pre seasoned cast iron, the 4 piece modular construction feels like a tank and is built to last for generations. The non toxic finish uses only iron and vegetable oil, so you get PFAS free cooking with the easy maintenance Lodge is known for.
There are tradeoffs to that durability. At over 33 pounds it is far heavier than sheet metal alternatives, so it is portable but not lightweight. Like all cast iron, it needs prompt cleaning and occasional oiling to prevent rust, and the ash pan lacks a retainer so it can slide if the grill is tilted during transport.
Overall, the Sportsman's Pro is a superb choice if you want a compact grill that cooks like a full size workhorse and will not rust out after a season. If you prioritize featherweight carry and zero maintenance, look elsewhere, but for flavor, longevity and American made quality, this hibachi is hard to beat.

The Lodge 15 x 12 Inch Cast Iron Grill Topper turns any gas, charcoal, or camp grill into a versatile outdoor kitchen. It is designed for grillers who love shrimp, fish, diced vegetables, and other small foods that normally slip through the grates, including campers who need a packable yet spacious solution.
In real world use, the signature teardrop perforations keep food contained while letting smoke and flame infuse authentic grill flavor.

Build quality is a standout, crafted in America from solid cast iron and pre-seasoned with 100 percent natural vegetable oil. The smooth interior, generous rectangular surface, and dual-handle design make it stable and easy to maneuver, while the non-toxic, PFOA and PTFE free construction reflects Lodge family standards since 1896.
Like all cast iron, it requires more care than lightweight steel alternatives. It must be hand washed, dried immediately over heat, and lightly oiled to prevent rust, and the entire pan gets extremely hot on the grill. Its weight and 15 inch footprint also mean it may not fit compact grills easily.
Overall, this grill topper is a durable, high performance upgrade that solves the most common grilling frustration. If you want smoky, evenly cooked vegetables and seafood without losing food to the fire, and you value heirloom quality cookware that gets better with age, it is an excellent investment.

The Char-Broil Universal Cast Iron Grate is a replacement cooking grate designed to fit a wide variety of charcoal grills. It is ideal for anyone with an older or non standard grill who needs a reliable replacement without hunting for an exact model match.
In real world use, the adjustable design expands smoothly from 14 to 19.5 inches to cover most firebox sizes. The cast iron core holds heat exceptionally well, delivering even cooking and strong sear marks that enhance flavor on meats and vegetables.

There are a few tradeoffs to consider. At 7.75 inches wide, a single grate may not fully cover larger grills, so you might need two for complete coverage. Like all porcelain coated cast iron, it needs gentle handling to avoid chipping and regular cleaning to maintain its finish.
Overall, this is a smart, durable and versatile upgrade for outdoor charcoal grilling. If you want universal fit, excellent heat retention and easier maintenance than raw cast iron, this Char-Broil grate is a dependable choice that delivers great value.

In real world use, the smooth griddle side excels at pancakes, bacon, eggs and sandwiches while the ridged grill side sears steaks, burgers and vegetables with authentic grill marks. The pre-seasoned surface provides natural nonstick release and even heat retention, and it performs consistently on gas, electric, induction, oven, grill or campfire.
Built from solid cast iron in the USA, this 9.4 pound pan feels like a true heirloom piece with outstanding durability and heat retention. The rectangular low profile design maximizes usable cooking area and the construction is free from synthetic coatings, PFOA and PTFE, using only iron and oil.
The weight and size that make it so capable also make it cumbersome to lift and store, especially when hot. The low edges can allow grease or liquids to spill if overloaded, and the perfectly flat bottom may rock slightly on uneven burner grates without a small foil shim.
Overall, the Lodge Double Play delivers exceptional versatility, durability and everyday value for anyone who cooks for a crowd or loves indoor and outdoor cast iron cooking. If you want a single long lasting pan that replaces separate griddles and grill pans, this is a top choice.

Preheat gradually on low to medium heat to ensure even heating and prevent warping. Use on two burners for best coverage and avoid thermal shock by not placing a hot pan in cold water.
Use metal or wooden utensils safely, but avoid dishwasher, harsh detergents and prolonged soaking to protect the seasoning.
Head-to-Head: Lodge Sportsman’s Pro Cast Iron Grill vs 13″ Cast Iron Cooking Grid for S/MiniMax Big Green
Both products promise the classic cast iron advantages of fast heat conduction, even heating, and beautiful sear marks, but they deliver those benefits in very different packages. Below is how they compare on the four factors that matter most when you are deciding between a new grill and a grate upgrade for your outdoor kitchen.
Build Material and Heat Retention
The Lodge Sportsman’s Pro Cast Iron Grill is built as a complete grill from durable, heavy-duty cast iron with a traditionally crafted finish made only from iron and vegetable oil, which means it is PFAS-free and designed to retain heat for consistent charcoal cooking. That mass helps it hold steady temperatures once it is hot, and its dual air vents give you adjustable heat control without needing to swap any parts.
The 13″ Cast Iron Cooking Grid for S/MiniMax Big Green takes a more focused approach, using thick cast iron sticks with a tight gap pattern to create a dense, heavy main cooking surface that heats quickly and evenly. Owners commonly report that its thickness helps preserve seasoning and smoky flavors while leaving defined grill marks, and the brand recommends oiling the surface before first use and protecting it after cooking to prevent rust. If you want a full heat-retaining vessel you can move to campsites and tailgates, Lodge has the edge, if you want a dense grate that upgrades heat contact inside an existing kamado, the Quantfire grid is purpose built for that.
Fit, Size and Compatibility
Fit is where these two diverge the most. The Lodge Sportsman’s Pro Cast Iron Grill measures 9 x 16.75 inches as a standalone rectangular grill, so you do not need to worry about compatibility with another cooker, you set it up and cook directly on its removable grate. That makes it ideal if you are adding a secondary grill to an outdoor kitchen island or need a portable option that does not depend on your main grill’s dimensions.
The 13″ Cast Iron Cooking Grid for S/MiniMax Big Green is a round 13-inch grate made specifically to fit Small and MiniMax Big Green Egg models and other charcoal grills with the same diameter. You will want to confirm your grill’s interior size before ordering, since it is not universal, but when it fits, it sits as your primary cooking surface with minimal wasted space. For broader outdoor kitchen planning, you may also want to review best pizza oven outdoor for backyard to see how a dedicated grate versus a full grill fits alongside other stations.
Cooking Experience and Versatility
On the Lodge Sportsman’s Pro Cast Iron Grill, the cooking experience centers on charcoal control and access, the removable grate simplifies adding charcoal and cleanup, while the dual vents let you fine tune airflow for searing or slower cooking. Because the entire body is cast iron, you get edge-to-edge heat retention that supports everything from burgers and steaks to vegetables, and you can use it at campsites, cookouts, or as a dedicated sear station next to your main outdoor kitchen countertop.
The 13″ Cast Iron Cooking Grid for S/MiniMax Big Green is all about grate-level performance inside a kamado, its thick sticks and short gaps mean even small foods are less likely to fall through, and the cast iron surface is designed to hold seasoning and deliver even heating with prominent grill marks. It does not add a new firebox or vents, so your temperature control still comes from your Egg or charcoal grill, but it upgrades what touches the food. If your current grill runs well but your factory grate is thin or widely spaced, this grid changes the cook more directly than adding another grill.
Portability, Maintenance and Everyday Use
For portability and setup, the Lodge Sportsman’s Pro Cast Iron Grill is designed as a portable charcoal grill for tailgates and campsites, yet that same heavy cast iron construction means it is heavier to move than a sheet-metal portable and benefits from regular seasoning care. Lodge notes it is made in the USA and is versatile and easy to clean when you follow cast iron care, and the removable grate helps with ash access so daily use is straightforward once you learn vent control.
The 13″ Cast Iron Cooking Grid for S/MiniMax Big Green is lighter to handle as a single grate, but it still requires classic cast iron maintenance, oiling before use and proper drying and protection after to avoid rust. It does not add extra parts to store, you simply swap it for your existing grate, which keeps your outdoor kitchen footprint unchanged. If you have ever dealt with a finicky gas setup, the troubleshooting mindset in gas grill 4 burner Won’t Light? 5 fixes before you call for service is a good reminder that a simple grate swap often solves more cooking frustrations than adding a whole new appliance.
Another option worth a look if you want cast iron versatility without committing to either of these two is the Lodge Reversible Cast Iron Grill/Griddle Pan, which covers two burners and flips from grill to griddle for indoor or outdoor use, but for this head-to-head we are staying focused on the full grill versus the dedicated round grate.
Which One Should You Get
Choose Lodge Sportsman’s Pro Cast Iron Grill if you want a complete, portable charcoal grill that brings heavy-duty cast iron heat retention to any outdoor space without relying on an existing cooker. You get a self-contained 9 x 16.75 inch cook surface, dual vents for control, a removable grate for easy charcoal access, and a PFAS-free vegetable oil finish that fits naturally into an outdoor kitchen where you want a dedicated sear or small-cook station you can also take on the road.
Choose 13″ Cast Iron Cooking Grid for S/MiniMax Big Green if you already own a Small or MiniMax Big Green Egg or a same-size round charcoal grill and want to maximize what that cooker can do. You keep your current firebox, vents, and countertop layout, and you gain a thick, tightly spaced cast iron main cooking surface that heats fast, holds seasoning, and helps keep small foods on the grate while delivering strong grill marks, all without adding another grill to store or maintain.
Who Should Skip Both
Both of these options are not ideal for someone who wants a low-maintenance, lightweight, or large-capacity primary grill for a big family or for frequent high-volume entertaining. If you need a wide cooking surface that feeds six or more at once, want stainless steel or porcelain convenience with minimal seasoning, or prefer a built-in gas island that lights instantly without charcoal handling, neither the compact Lodge grill nor the 13-inch round grate is the right choice, and you would be better served by a full-size gas or pellet system.

Frequently Asked Questions
Can the 13″ Cast Iron Cooking Grid for S/MiniMax Big Green fit any charcoal grill or only Big Green Egg?
It is designed for Small and MiniMax Big Green Egg, but it can work in other charcoal grills with the same 13-inch round grate size. You should measure your current grate diameter and interior clearance before ordering, since a round grate needs an exact fit to sit securely and allow the lid to close properly.
Do I need to season both grates and how do I prevent rust on cast iron grill grates?
Yes, both benefit from seasoning, Lodge pre-seasons with vegetable oil and recommends continued oiling and proper cleaning, while Quantfire advises applying oil before first use and protecting the grate after each cook. Hand wash with warm soapy water, dry thoroughly immediately, and apply a thin oil layer before storing to help prevent rust, especially in humid outdoor kitchens.
Which is better for an outdoor kitchen countertop setup: a standalone cast iron grill or a replacement grate?
A standalone like the Lodge Sportsman’s Pro Cast Iron Grill adds a separate charcoal station that does not tie up your main grill or countertop cutout, which is great for dedicated searing or portable use. A replacement grate like the 13″ Cast Iron Cooking Grid keeps your countertop layout unchanged and upgrades sear quality inside your existing kamado, so choose based on whether you want an extra cooker or a better surface in the cooker you already have.
