3 Burner Gas Grills Buying Guide

The search for the best 3 burner gas grill doesn’t have to be complicated. While it’s mainly going to depend on your preference, there are a couple of things you should look out for. 

In this buying guide and reviews, we’re discussing what factors you need to consider when you purchase a new grill. We’re also going to answer some questions we get asked all the time.

Alternatively, you can also check our Cookshack PG500 review.

3 Burner Gas Grills Buying Guide


Gas grills are often left in the backyard or a partially exposed area where they have to endure environmental elements. Search for a grill that’s able to handle all that without suffering from rusting or corrosion. This rule also applies to other kinds, including our favorite 4 burner gas grills.

Stainless steel, cast iron, and porcelain-coated cast-iron are the best materials you should consider. Aluminum is another great one. However, they tend to deteriorate much more quickly compared to stainless steel.

Of course, you want your 3 burner gas grill to last for years. Looking at the material is important because it makes performance even better. Also check reviews and the terms of the warranty, as this is an indication of the manufacturer’s confidence on the gas grill.

If you're looking for a portable size grill, there are a lot of portable product options like Weber and Char-Broil. Some portable Weber ones include Weber Smokey Joe and Weber Go-Anywhere. We like porcelain-enameled grates for the cooking area in portable grills like in the Spirit.

You can pick a product model that comes with good wheels so it's easy to start using the grill.


British Thermal Units or BTUs refer to the amount of heat generated by a grill. You’d want to select grills with at least 30,000 BTU total. If there’s a side burner for extra space, it should have an additional 10,000 BTU of heat.

A high total BTU isn't a measure of how hot the grill is. It's more like a fuel efficiency rating.

While it can be tempting to purchase a gas grill with a higher BTU, that also means it uses up more fuel. This means you have to spend more on fuel especially if you’re going to be grilling often.

So whether you use natural gas or propane, consider this factor. Ideally, choose a product that has 80-100 BTUs per square inch of cooking space. 



Looking for good material for the grates is also important. The most commonly used materials are cast iron, stainless steel, or porcelain-coated cast iron or steel.

  • Cast Iron.Cast iron grates usually cost more because it’s heavier compared to other materials. However, it’s ideal because it gets really hot and it holds in heat evenly and more effectively. This helps cook the food faster and leave even grill marks too. The main drawback with cast iron grates is it makes maintenance harder.
  • Porcelain-coated cast iron or steel.Porcelain has a low price, but there are some things you should note. Porcelain-coated cast iron or porcelain enameled cast-iron cooking grates are more prone to chipping, so you must choose a high quality porcelain for it to last longer. Some models like the Weber Spirit have porcelain enameled cast-iron cooking grates.
  • Steel.This is by far the most affordable in price, but the performance is not really the longest lasting. Repeated use can cause the steel to develop a rough surface. That makes it lose its non-stick abilities. However, it will take a lot of time especially if you clean the grates often.  

Porcelain-enameled grates are common with Weber or Char-Broil products. Some good ones with porcelain-enameled grates include Weber E-310, Weber S-310, and Char-Broil Classic.

Other Features

It's good to consider other features such as flavorizer bars, side tables, tool hooks, infinity ignition, caster wheels, or a grease management system.

Char-Broil burners usually have flavorizer bars, although these flavorizer bars can be differently named in another product line. Another Char-Broil feature is the infinity ignition, which lights up every time the grill is used.

A grease management system is also useful for easy cleanup. Grease can harden, and that makes it harder to clean. It will be way easier if your grilling system is made with a grease management system added for cleaning up the grease in no time. Also, tool hooks can come handy.

Another brand we haven't covered is the Char-Griller. One of their models has 438 square inches of cooking space, porcelain-coated cast-iron grates, and a 12,000 BTU side burner. The total cooking space of 438 square inches is smaller than the 529 square inches cooking area of the Weber Spirit II.

Aside from Char-Broil, you'll find a good product line with Weber, Broil King, and Royal Gourmet. If using a big grilling system is for you, Royal Gourmet has super-sized models with a large grilling system.

A lot of reviews say Weber is also a good product pick for those who want to start at a low price. 

Frequently Asked Questions

What are the advantages of a 3 burner gas grill?

A 3 burner grill provides you three things: efficiency, durability, and practicality.

You can think of the 3 burner grill as the middle ground between small grills and large ones, because it's still easy to cook for a lot of people even if you don't have much space. If you need to go bigger, then 5 burner gas grills are preferred.

If you’re convinced that you can’t accommodate a new bulky grill yet you still want to cook for a lot of people, a 3-burner grill is a worthy investment.

Secondly, a gas grill is long-lasting since it’s made from durable material such as steel. That makes it great to use for many years.

Lastly, gas grills are more cost effective than their charcoal counterpart. Gas has a low price compared to charcoal, so you’re able to save money when using a grill. Plus, burners are more flexible with temperature control. [1]

What are the advantages of a 3 burner gas grill?

How long should a gas grill last?

Gas grills should be able to last a decade or more. You just have to clean them after every use and make sure they deliver a great performance. (Have infrared instead? Here's how you clean an infrared grill.)

Check the terms of the warranty as well because that’s a good indication of how long they last.

Is a gas grill worth it?

Well, if you’re a regular backyard griller or you want to have that outdoor cooking experience, gas grills are the perfect investment. It's easy to cook burgers, steaks, and other types of food and serve them to your family and friends.

And of course, it’s always more than just the food. You can't pay a price for the bonding and memories you’ll have when you got a reliable product at home.

Do I need a side burner?

The short answer to this question is no, you don’t really need to have a side burner. However, it could come pretty useful if you want to cook vegetables, create sauces, or other food in a separate area.

The real function of a side burner lies in the fact that you could cook food at a different temperature. For instance, an 8,000 BTU side burner provides just enough heat for cooking seafood evenly.

You can also use it to boil veggies. Just use a pot and place it on the burner and you’re done in no time. 

What extra features should I consider?

The best 3 burner gas grills can be outfitted with a bunch of different features that can make your life easier. Aside from the main burner, you can also get a product with a rotisserie or a side burner.

Some of the best gas grills also have side shelves you can use. Side shelves are great to have if you want an extra workspace to place cooked food or your cooking tools.

What extra features should I consider?

Other features you should consider in reviews are a warming rack, temperature gauge, total size of the cooking space, interior lighting, exterior lighting, temperature control, and tool hooks. A warming rack is especially useful because you can use it to heat up food or just keep the meat hot after it’s done cooking.

As for lights, it’s pretty useful to have a lighting system if you’re going to be grilling at night and you want to easily navigate the cooking surface and the knobs. Some product options have LED front panel lighting and interior halogen lights installed.

How do I choose a gas grill?

The first thing you should consider is size and cooking space. A way to determine the size is by measuring the space you have in inches. On top of that, consider how many people you’re planning to cook for on a  regular basis. This comparison of 2 and 3-burners should give you a better idea.

After you’ve set your heart on the size you want, that’s when you consider other features such as material, cooking power, fuel type, temperature control, warming rack, rotisserie kit, and other convenient features.
