At a Glance: Our Top Picks

If you’re looking to make the step up to an outdoor kitchen to brag about, then a built-in gas grill will prove to be an excellent investment.

Drop-in propane grills aren’t just big for big’s sake. Because they’re fixed in place, they can be linked to a natural gas line, giving you a convenient, cheaper supply of fuel in constant supply.

Gas cookers might have their detractors, but when they’re as powerful as these units they are more than capable of creating beautiful barbecued food.

Let’s get into the very best out there today.

We kick off our list with simply the very best fixed unit grill out there: The Napoleon LEX

This propane-powered grill comes with an incredible 850 square inches of cooking space, giving you more than enough room to really get stuck into it.

Another innovation that I’m a huge fan of is its sear plates. These high-heat discs are designed to rapidly vaporize any drippings or run-off from your meat, which helps reduce flare-ups and improves the overall cleanliness of your grill.

The grill’s excellent performance is largely helped by its excellent infrared stainless steel burners, housed in the main drum of the grill.

The infrared burner located at the bottom ensures you get perfect searing. It also has I-GLOW backlit knob that ensures you continue cooking even when darkness sets in.

It’s packed with other little bonuses that you expect to see in an elite level unit, like a pre-installed temperature gauge, easy-lift lid, and detachable drip pan.

FAQ

As you can no doubt tell from the name, built-in outdoor grills (also called ‘drop-in grills‘ or ‘grill insert’) are fixed to a cooking surface in your garden or patio. They’re pretty intimidating units, but what they lack in mobility they more than make up for in their power.

They offer you superior performance to traditional charcoal or portable propane models. Their expensive price proves that they are for serious grillers, but they are perfect for barbecue parties.

If you’re a serious BBQ enthusiast, then this could be the missing piece of the puzzle for your DIY outdoor kitchen.

What exactly is BTU power?

BTU is shorthand for British Thermal Unit, and is the unit of measurement used to quantify the maximum power output of your grill.

drop in gas grill placed in outdoor kitchen bbq island

Quite often these are expressed per burner in your grill, as well as a total output number. So it’s not uncommon to see a grill listed as 3x 16,000 BTUs, and also 48,000.

I recommend going high when choosing your built-in grill. This isn’t just vanity metric however. Higher BTUs tend to mean quicker startup time, as well as a greater range of temperature available to you when you cook.

Also keep a look out for infrared burners. These beauties work by converting the heat from a standard gas burner into infrared energy, which is far hotter and consistent, and doesn’t lead to flare-ups.

This makes infrared burners perfect for the searing and caramelizing methods that we all associate with good barbecue.

How heat-efficient are built-in gas grills?

I’ve written a lot before about the importance of maintaining good grill temperature. This is just as true for gas grilling as it is for charcoal.

A grill that leaks heat is useless, and it doesn’t matter if it cost ten dollars or ten thousand. The moment it loses heat levels, it’s useless.

Pay close attention to two things: Heat retention and heat distribution.

grill insert large cooking surface

Drop-in grill heads offers massive amounts of cooking and grilling space

Having a unit with excellent insulation will ensure good heat retention and that your chamber’s ambient temperatures are able to stay stable for as long as you need them. Look out for models that are listed as double walled, as these tend to be especially strong at retaining heat.

Good heat distribution will provide even temperatures across the surface of your grill gates. Flare-ups are far more common in gas grills, but luckily the introduction of infrared burners and porcelain grates are helping to combat this.

How much cooking space do I need?

Any good built-in grill should come with ample cooking space. More space gives you the opportunity not just to cook more, but also to cook faster. It also gives you the opportunity to take on more advanced gas grilling skills, like indirect grilling.

Opinions will vary, but for me the ideal primary cooking space size for a drop in unit is anywhere between 500 and 900 square inches.

Another factor to consider is the grill’s appearance. This might seem frivolous, but just because you will be using the unit to prepare food doesn’t mean it should be hideous. A huge and weird-looking grill will stick out as an eyesore on your patio.

Choose a smart grill that comes with an impeccable design and modern layout. A grill should complement your patio, not the other way round.

What’s the best ignition system?

One of gas grills’ biggest selling points is how easy and quick it is to get them going. Where charcoal can take the best part of half an hour, gas systems can be done in an instant. This is thank to their ignition systems.

Not every system is the same however, and there are in fact three main types of ignition system.

The Piezo Electric Ignition System is the most widely used, and is built with a simply starter button. If you’ve ever pressed an ignition button and heard a click then chances are that you’ve used a Piezo.

Far less common are the hot surface system, which is a high-end function that uses rods to light the burners, and electronic systems that rely on batteries to operate.

Neither of these are ideal. Hot surface systems are far too prone to faltering, and electronics require new batteries routinely, which can easily build up costs and derail your barbecue.

How to install a built-in grill

Exactly where you choose to put your BBQ island and drop-in can depend on a number of factors, so for a full guide be sure to check out this article from This Old House. In a nutshell though:

Identify a good area for your island by considering somewhere that’s a safe distance away from your house should there be complications with electricity, fire or gas. Also be sure that the area you build in is dry and shielded from wind.

Set up your BBQ island. This in itself is a big job, so be sure to check out our guide on how to build a BBQ island with steel studs, and check out our guide to DIY BBQ islands for some ideas. Doing this will give you a permanent fixture on which to install your drop-in grill head, as well as give you a counter surface around which to cook.

In Conclusion

The five reviewed built-in grills are the best you will find on the market and each has its own great unique features.

However, the Lion L75623 Premium Grill tops the list.

This is a grill worth buying due to its numerous benefits. It is sturdy, long-lasting and still, you will find it at a pocket-friendly price. Besides, it has ample cooking space to prepare food for a multitude of people. The 75,000 BTUs coupled with the high-grade stainless steel grates will definitely meet all your cooking needs.
