If you enjoy charcoal grilling but want more control over cooking temperatures, a Santa Maria-style grill attachment can be an interesting upgrade. Instead of adjusting heat only by changing airflow or moving charcoal, this cooking system lets you raise and lower the food above the fire.
The Onlyfire Santa Maria Grill Rotisserie System brings this style of live-fire cooking to a compatible 22-inch kettle grill. It combines an adjustable cooking grate with a rotisserie attachment, giving backyard barbecue enthusiasts more ways to prepare steaks, chicken, ribs, vegetables, and other foods.
But is it sturdy, versatile, and worth the asking price? In this Onlyfire Santa Maria Grill Rotisserie review, we examine its construction, features, cooking performance, compatibility, customer feedback, advantages, and potential drawbacks.
What Is the Onlyfire Santa Maria Grill Rotisserie?
The Onlyfire Santa Maria Grill Rotisserie System is an accessory designed to transform a compatible 22-inch Weber kettle grill into an adjustable-height Santa Maria-style barbecue.
Traditional Santa Maria grilling uses an open fire and a cooking grate that moves vertically. Moving the grate closer to the fire increases heat exposure, while raising it creates a gentler cooking environment.
Onlyfire brings this approach to a kettle grill with a hand-crank lifting mechanism and a removable rotisserie attachment.
The result is a two-in-one outdoor cooking setup:
- An adjustable grate for direct grilling and open-fire cooking.
- A rotisserie system for turning and roasting larger foods.
Rather than buying a separate Santa Maria grill, owners of compatible kettle grills can add more cooking flexibility to equipment they already own.
The product is listed on Onlyfire’s official website at approximately $150.99, although prices and availability can change.

Design and Build Quality
The Onlyfire system uses a metal frame that sits on top of a compatible kettle grill. Its stainless-steel construction is intended to withstand outdoor cooking temperatures and regular barbecue use.
The main feature is the vertically adjustable cooking grate. A hand crank allows the user to raise or lower the grate according to the intensity of the fire.
This is particularly useful when cooking foods that require different heat levels.
For example:
- Steaks can be lowered closer to the charcoal for stronger searing.
- Chicken can be cooked farther from intense flames.
- Vegetables can be moved away from hot spots to reduce burning.
- Larger cuts can be roasted more gently.
The system also includes a rotisserie mounting arrangement, allowing users to switch between conventional grilling and rotating-roast cooking.
Customer feedback on Onlyfire’s product page is generally positive, with reviewers praising the versatility and usefulness of the adjustable grate. Some users, however, mention that the lifting cable is relatively thin and may need attention over time.
One reviewer reported a broken cable but also described receiving replacement cables from Onlyfire at no charge. Another recommended securing the crank handle because it could loosen during use.
These comments suggest that the design offers useful functionality, but periodic inspection and maintenance are sensible.
Adjustable Height: The Biggest Advantage
The ability to change the cooking grate’s height is arguably the strongest reason to consider this product.
On a conventional charcoal kettle, heat management often involves adjusting the air vents, moving charcoal, or rearranging food. Those techniques work, but they do not always provide immediate control over how close the food sits to the fire.
The Onlyfire system takes a different approach.
With the hand crank, the cooking grate can be raised or lowered while the charcoal remains in place. This gives the cook another way to manage heat exposure.
Why Does This Matter?
Better searing: Lowering the grate brings food closer to the fire, helping achieve a stronger sear when conditions are suitable.
Gentler roasting: Raising the grate reduces direct heat exposure, which can help prevent the outside of larger cuts from cooking too quickly.
More flexible cooking: Different foods can be cooked at different heights depending on their thickness and desired finish.
Less food handling: Instead of constantly moving food around the cooking surface, you can adjust the grate itself.
The height adjustment does not replace good fire management. Charcoal quantity, wood choice, airflow, and food placement still matter. However, it adds a useful control that ordinary kettle grills do not provide.
Rotisserie Performance
The rotisserie attachment expands the system’s capabilities beyond standard grilling.
A rotating spit is particularly useful for whole chickens, smaller roasts, and other foods that benefit from continuous rotation over a heat source.
Onlyfire lists a rotisserie speed of approximately 2–3 revolutions per minute and uses a 5/16-inch square spit rod.
Potential uses include:
- Whole roasted chicken.
- Pork roasts.
- Small beef roasts.
- Rotisserie-style kebabs.
- Other suitably balanced cuts of meat.
Continuous rotation can help expose food evenly to heat, although results depend on the fire arrangement, food size, balance, and distance from the charcoal.
One practical consideration is the motor’s power source. Customer feedback mentions using relatively large batteries, so buyers should check the supplied motor and power requirements before purchasing rather than assuming it uses a standard rechargeable battery.
The rotisserie is a useful addition, but users should ensure food is securely balanced on the spit and that the motor is not overloaded.
What Can You Cook With It?
The system is particularly suitable for people who enjoy experimenting with charcoal and wood-fired cooking.
Steaks and Burgers
The adjustable grate makes it easier to position steaks at a suitable distance from the fire. Lower positions can help with searing, while raising the grate provides more moderate cooking.
Chicken
Chicken pieces can be grilled on the adjustable grate, while a whole chicken can be prepared using the rotisserie attachment if its size and weight are appropriate.
Fish and Vegetables
Fish and vegetables can be particularly sensitive to intense heat. The ability to raise the cooking surface gives the cook another way to reduce scorching.
The versatility is one of the strongest reasons to consider the attachment over a conventional fixed-height kettle grate.
Installation and Compatibility
The Onlyfire Santa Maria system is designed primarily for compatible 22-inch kettle grills.
Before ordering, measure your grill and check the manufacturer’s compatibility information carefully.
Onlyfire specifically states that the product is not compatible with the Weber Smokey Mountain Cooker or the 22-inch Slow ‘N Sear kettle grill.
Do not assume that every grill described as 22 inches will fit. Lid geometry, rim dimensions, mounting points, and other design differences can affect installation.
Assembly involves mounting the frame, installing the lifting mechanism, positioning the cooking grate, and attaching the rotisserie components.
Customer reviews generally describe assembly as manageable, although the instructions may require some interpretation. Check that the grate is level and that the lifting mechanism moves smoothly before lighting a fire.
Cleaning and Maintenance
Like most charcoal-grilling equipment, the Onlyfire system needs regular cleaning and maintenance.
Useful care practices include:
- Allow the equipment to cool completely before cleaning.
- Remove food residue and grease from the grate.
- Clean the rotisserie spit and accessories after use.
- Check the lifting cable and its attachment points periodically.
- Inspect the crank handle and mounting hardware.
- Store the equipment in a dry place or use a suitable protective cover.
Some customer feedback suggests that the lifting cable may be a wear item. Having access to replacement parts is therefore worth considering.
The official product page lists stainless-steel construction, but that does not mean every component is immune to corrosion or wear. Cleaning and proper storage remain important.
Customer Reviews: What Are Buyers Saying?
The official Onlyfire listing displays 73 reviews, with 58 five-star ratings and 15 four-star ratings at the time of the available product information.
That is a favorable rating distribution, although reviews published on a manufacturer’s own store should not be treated as a substitute for broader independent testing.
Positive comments commonly mention:
- Good value compared with more expensive Santa Maria systems.
- Useful adjustable cooking height.
- Easy assembly for many buyers.
- Compatibility with suitable Weber kettle grills.
- The convenience of combining grilling and rotisserie cooking.
- Responsive customer support in at least some reported replacement-part cases.
Reported drawbacks include:
- A lifting cable that some users consider too thin.
- A crank handle that may loosen.
- Basic assembly instructions.
- Some movement or wobbling in the mounting brackets.
- A cooking grate that may sit higher than the original kettle grate.
One buyer noted that the elevated position of the attachment could make it harder to bring the cooking grate as close to the charcoal as with the original kettle setup. This is an important consideration if you regularly cook small portions directly over intense heat.
Overall, the feedback suggests a useful accessory with some mechanical details worth monitoring.

Is the Onlyfire Santa Maria Grill Rotisserie Worth the Price?
At approximately $150.99 on the official US product listing, the Onlyfire attachment occupies an interesting position in the outdoor-grilling market.
A standalone Santa Maria grill can cost considerably more, while this system allows compatible kettle owners to experiment with adjustable-height live-fire cooking using equipment they already have.
The value proposition is strongest if you regularly cook different foods and want more control over the distance between the food and the fire.
It is less compelling if you primarily cook burgers and sausages on a standard kettle or rarely use a rotisserie.
For buyers in India, imported pricing can be substantially higher after shipping, customs duties, and retailer charges. One India-facing marketplace listing showed a price around ₹6,279, but marketplace prices, stock, delivery conditions, and return protections can change. Check the final checkout price before ordering.
Final Verdict: Should You Buy the Onlyfire Santa Maria Grill Rotisserie?
The Onlyfire Santa Maria Grill Rotisserie System is a worthwhile upgrade for compatible 22-inch kettle owners who enjoy open-fire cooking and want more control over heat exposure.
Its biggest strengths are the adjustable grate, rotisserie functionality, relatively compact design, and the ability to turn an existing kettle grill into a more versatile cooking station.
The main compromises involve cable durability, mounting stability, assembly, and grill compatibility. These are not necessarily deal-breakers, but they should be considered before purchasing.
Overall, it is a compelling accessory for backyard barbecue enthusiasts who want to experiment with Santa Maria-style cooking without buying a full-size standalone grill.
If you already own a compatible Weber kettle and regularly cook steaks, chicken, ribs, or vegetables over charcoal, the Onlyfire system deserves serious consideration. If you rarely use your grill or need a guaranteed heavy-duty commercial setup, a more substantial standalone Santa Maria grill may be a better investment.
