A built-in side burner gives you a separate place to simmer sauce, boil water, or cook a side dish while your main grill handles the entrée. The right choice depends on more than burner power: check the countertop cutout, confirm the fuel setup, and make sure the cover and materials suit your outdoor kitchen. These five single-burner options range from natural-gas-only models to convertible designs, with different dimensions and heat outputs to compare.

Our Picks: Best Side Burners For Outdoor Kitchens reviews
Qualipo: A 15,000 BTU Burner with a Full-Cover Lid
The Qualipo is a single drop-in burner designed to add a separate cooking zone beside your main grill. Its 15,000 BTU cast brass burner is suited to tasks such as boiling, frying, simmering, and preparing sauces while the grill cooks the main dish.
The body is made from 304 stainless steel, and the product description specifies a substantial 8 mm plate. A full-coverage lid helps shield the cooking area from wind, rain, dust, and debris when the burner is not in use. The listed overall dimensions are 19.7 by 12.7 by 4 inches, but you should confirm the required cutout dimensions before modifying a countertop.
This is a flexible option if you are deciding between propane and natural gas. However, the listing does not explain the conversion steps or which fittings are included, so confirm the exact setup and installation requirements before purchase. Compared with the 12,000 BTU models here, it offers higher stated output; that makes it a useful candidate if you expect to boil or fry often, though burner power alone does not guarantee a particular cooking result.
Pros:
- 15,000 BTU cast brass burner
- 304 stainless steel body with stated 8 mm plate thickness
- Full-cover lid helps protect the burner between uses
- Designed for propane or natural gas setups
Cons:
- Cutout dimensions are not provided in the supplied product details
- Fuel conversion and included components should be confirmed before installation
Verdict: Choose the Qualipo if you want a higher-output burner with a protective lid and need a product described for both common outdoor gas fuels, but verify fit and fuel configuration first.
Hvlwyaz: A Convertible Burner with a Reinforced Grate
The Hvlwyaz provides 12,000 BTU of heat for everyday side-burner jobs such as simmering, sautéing, boiling, and stir-frying. Its brass burner cap is intended to retain heat, while the reinforced 8 mm grate is designed to support cookware such as woks, stockpots, frying pans, and kettles.
The unit measures 11 by 20.6 by 7.1 inches and is designed to drop into an outdoor kitchen island. Its 304 stainless steel surface and full-height cover are practical features for an appliance exposed to outdoor conditions. The removable grate also makes the cooking surface easier to access for cleaning.
This model is configured for liquid propane, with an LP regulator and propane nozzle installed. The product description says it can be converted to natural gas by replacing the nozzle, but you should check whether the required NG nozzle is included and follow the manual and local gas rules. Its stated dimensions are useful for planning, but confirm the actual cutout requirements before cutting your countertop.
Pros:
- 8 mm grate is designed to support a range of cookware
- Brass cap and 12,000 BTU output suit common side-dish tasks
- 304 stainless steel surface with a full-height protective cover
- Compact drop-in format for outdoor kitchen islands
Cons:
- Configured for propane; natural-gas conversion requires the correct nozzle
- Confirm the cutout dimensions and conversion parts before installation
Verdict: The Hvlwyaz is a practical pick if you want a reinforced grate and plan to use propane, or if you have confirmed the parts and instructions needed for natural-gas conversion.
Stanbroil: A Straightforward Natural-Gas-Only Option
This Stanbroil single side burner is made for outdoor kitchens with a natural-gas supply already plumbed to the cooking area. Its 12,000 BTU cast brass burner adds a separate spot for sauces, sides, and other cookware while your main grill is in use.
The burner body and cover are made from 304 stainless steel, and the cooking grid is removable for cleaning. The product lists an overall size of 13.8 inches wide by 21.8 inches deep by 6.6 inches high, with a cutout size of 11 by 19 by 5.9 inches. Those measurements make it easier to plan a compatible island opening, but measure your own countertop and compare it with the installation instructions before buying.
The main trade-off is fuel flexibility: this model is natural gas only, so it is not a fit for a propane-only setup. If you already have a natural-gas line in place, the simpler fuel choice may be appealing. If you may change fuel types later, one of the convertible models in this roundup is a better match.
Pros:
- 12,000 BTU cast brass burner for everyday cooking tasks
- 304 stainless steel construction with a removable cover
- Cutout dimensions are provided for planning
- Removable cooking grid supports easier cleanup
Cons:
- Natural gas only; requires a natural-gas line at the cooking area
- Not suitable for a propane-only outdoor kitchen
Verdict: Pick the Stanbroil if your outdoor kitchen already has natural gas and its stated cutout dimensions match your island; skip it if you need propane or fuel conversion.
Sailret: A 15,000 BTU Burner with Conversion Parts Included
The Sailret is a single built-in burner with a stated output of 15,000 BTU. It is designed for supplemental cooking beside a grill, with enough stated output for tasks such as boiling, frying, and stir-frying.
Its 304 stainless steel body is intended for outdoor use, and the included stainless steel cover helps protect the burner area when it is not being used. The product description says it comes with an LP regulator and both NG and LP nozzles, with the LP nozzle set as the default. That makes the conversion components clearer than on some other dual-fuel listings, although changing the fuel setup still requires careful installation according to the instructions and local requirements.
The supplied details do not state the overall or cutout dimensions. That makes this model harder to assess for a planned drop-in installation than options with measurements listed. Before you buy, ask for the installation dimensions or check the product documentation, and do not rely on appearance alone to judge whether it will fit your counter.
Pros:
- 15,000 BTU output for higher-heat side cooking
- Product description lists both NG and LP nozzles and an LP regulator
- 304 stainless steel body with a protective cover
- Removable grille for different cooking tasks
Cons:
- Overall and cutout dimensions are not provided in the supplied details
- Fuel conversion and installation should be handled according to the manual and local rules
Verdict: The Sailret is worth considering if you want 15,000 BTU and included fuel-conversion parts, provided you can confirm the dimensions and installation requirements before ordering.
Hygrill: A Natural-Gas Burner with Detailed Cutout Measurements
The Hygrill is a 12,000 BTU single side burner for an outdoor kitchen with natural gas plumbed to the patio or deck. Its brass burner is intended for cooking sauces, eggs, soup, pasta, vegetables, and other sides while the main grill is occupied.
The product description lists a 304 stainless steel construction and gives both overall and cutout dimensions. The overall size is 4.5 by 12.5 by 19.5 inches, while the cutout is listed as 2.8125 by 11.25 by 18.25 inches. Check how those measurements are presented in the installation documentation and compare them with your counter before cutting. The listing also describes the unit as compatible with several sizes of built-in gas grills, but you should still confirm the opening and clearances for your specific island.
This is a focused choice rather than a flexible one: it is a natural-gas unit, not a propane model. If natural gas is already available and the cutout dimensions suit your project, its detailed measurements help with planning. If you need a lid or want the option to switch fuels, compare it with the other models before deciding.
Pros:
- 12,000 BTU brass burner for everyday side dishes
- 304 stainless steel construction
- Overall and cutout dimensions are provided
- Designed to pair with built-in outdoor gas grills
Cons:
- Natural gas only and requires a gas line at the installation site
- The supplied details do not mention a protective lid
Verdict: Choose the Hygrill if you have natural gas, want clear cutout measurements, and do not need a propane option or a listed cover.
How to Choose a Side Burner for Your Outdoor Kitchen
Match the fuel to your setup
Start by checking whether your outdoor kitchen is set up for natural gas or liquid propane. The Stanbroil and Hygrill models in this roundup are natural gas only. The Hvlwyaz is configured for propane and described as convertible, while the Qualipo and Sailret are listed for both fuels. For any conversion, check which parts are included, what the instructions require, and whether a qualified installer is needed. Follow local gas regulations.
Measure the countertop cutout
Do not choose a built-in burner by its overall dimensions alone. The appliance has to fit the opening in your counter, and the installation may require specific clearances. The Stanbroil, Hvlwyaz, and Hygrill listings provide dimensions, while the supplied details for the Qualipo and Sailret do not state a cutout size. Confirm the manufacturer’s installation measurements before cutting or ordering.
Choose output for the way you cook
The products here range from 12,000 to 15,000 BTU. A side burner can handle tasks such as simmering sauce, heating soup, boiling water, or cooking vegetables while your grill is busy. The higher-output models may suit jobs that call for more heat, but consider your cookware and typical meals too. BTU output is only one part of cooking performance.
Look at construction and outdoor protection
Several options list 304 stainless steel, and some include a cover to help protect the burner between uses. A lid can help keep wind, rain, dust, and debris away from the cooking area when it is closed, but it does not remove the need for routine cleaning and care. Check the listed materials, grate design, and cover details against how exposed your outdoor kitchen is.
Consider the cookware you plan to use
Think about whether you will mostly use a small saucepan or want to set a wok, stockpot, kettle, or steamer on the grate. The Hvlwyaz listing specifically describes its reinforced 8 mm grate as supporting a range of cookware. For other models, confirm the grate dimensions and weight guidance in the product documentation, especially if you use heavy pots.
Plan for installation and maintenance
A built-in gas appliance needs a suitable opening and a safe, correctly connected fuel supply. Review the manual before installation and use a qualified professional when required. Removable grates can make cleaning easier, while smooth stainless steel surfaces are generally straightforward to wipe down. Leave enough room in your kitchen design to access controls and clean around the unit.
Frequently Asked Questions
What is a side burner used for?
A side burner gives you a separate cooking surface beside your main grill. You can use it for sauces, sides, boiling, simmering, and other tasks that would otherwise take up space on the grill.
Can a natural-gas side burner run on propane?
Not automatically. The Stanbroil and Hygrill models listed here are natural gas only. Other products are described as supporting both fuels or as convertible, but you must confirm the required parts and setup before use. Never connect a burner to a different fuel without following the manufacturer’s instructions.
Are built-in side burners universal?
No. Overall dimensions and countertop cutout dimensions vary. Check the exact installation measurements and clearances for the burner you choose, then compare them with your outdoor kitchen plans.
Is 12,000 BTU enough for a side burner?
It can be suitable for common tasks such as simmering, heating sauces, and cooking side dishes. If you often boil or fry, you may prefer one of the 15,000 BTU models in this roundup. Your cookware and cooking habits also matter.
Does a side burner need a cover?
A cover helps shield the burner area from outdoor debris and weather when it is not in use. Several models here list a removable or full-coverage lid. Even with a cover, follow the care instructions and keep the unit clean and dry as directed.
Can I install a side burner myself?
Installation depends on the appliance, fuel connection, and local requirements. Read the product manual before starting. Gas work may require a qualified professional or permit, so check local rules and avoid improvising connections.
Which side burner is best if I need fuel flexibility?
The Qualipo and Sailret are described as supporting propane and natural gas. The Hvlwyaz is configured for propane and described as convertible to natural gas. Confirm the included fittings, conversion process, and installation requirements for the specific model before you buy.
Final Recommendation
For a higher-output burner with a full-cover lid, the Qualipo is a strong all-around candidate, provided you confirm its cutout size and fuel setup. The Sailret is another 15,000 BTU option and lists both fuel nozzles, but its dimensions need checking. If your kitchen already has natural gas, the Stanbroil provides stated cutout measurements, while the Hygrill is another natural-gas choice with detailed dimensions. Measure your island and verify the fuel connection before making your final decision.
