What are the advantages of a lid on a barbeque?
I have just bought a new half drum barbeque which can with a fold down lid.
I have heard that these lids are good for creating a smokey flavour, or for keeping food moist whilst it cooks. A lot of this seems to be based on peoples personal opinion with evidence based answers about what the benefits of cooking with the lid down are.
Does anyone have any evidence of exactly what cooking with a lid down on a barbeque actually does?
Best Answer
The lid can do one of three things:
Keeping the lid down increases the temperature of the air in the grill. This means that in addition to cooking with the direct heat of the coals, you are also cooking with convection of the air. This won't happen with the lid up.
In a charcoal grill, the temperature the coals burn is based on the airflow through the grill. Open is as hot as it will go (assuming the bottom vent is also open). By closing the lid and altering the airflow, you can control the temperature of the grill. My grill can keep fine temperature control between 200F-700F depending on how you set the airflow.
Which leads us to smoke. It seems obvious that if you are smoking, you will impart more flavor by trapping the smoke with your food rather than letting it float in to the sky. Additionally, you want wood to smolder not burn for your best smoke production. This works better at a lower temperature (see #2).

Is a BBQ with a lid better?
Heat will escape every time you lift the lid on a gas grill. As a result, when cooking with gas, leaving the lid on is generally going to be the most effective way to cook. This heat loss is not going to matter quite so much when you are cooking thin steaks or burger patties which need to be grilled directly anyway.Why put a lid on a barbecue?
When you close the lid to the grill, you're creating a convection. That is, the hot air coming from the heat source (gas or charcoal), trapped by the lid and unable to escape, moves around in the chamber you've created. Thus, the closed lid helps the interior of the meat cook through, much like an oven does.Is it better to BBQ with lid open or closed?
With the lid open, you get precise control over the heat hitting one surface of your food; with the lid closed, you still have the heat acting on the bottom of the food, but it also picks up heat from the air surrounding it, which can lead to mixed results.More answers regarding what are the advantages of a lid on a barbeque?
Answer 2
Keeps the Dog from stealing the meat on the grill!
Answer 3
It keeps the heat in, so you can switch techniques from a pure grilling technique (Open Lid, hot coals = direct radiant heat) to a baking/smoking technique.
For example, when I do a duck breast, I put all the heat on one side of the grill (i.e. 2/4 gas burners, or pile the charcoal on one side).
I sear the breast skin up directly over the heat, and then flip it to brown and crisp the skin. Once the fat starts to render, I get flare ups that are completely un-manageable.
The solution is to move the breast to the cool side, and shut the lid, so that it bakes and smokes for a few minutes to finish off the cooking.
Answer 4
Like the people say, open lid means directional heat from the coals. You'll cook the bottom of your food much faster than the top. You'll also get more air to the coals, so they'll be hotter, and to the food, which dries it out faster (at least in dry places like Calgary, where I live).
Closing the lid, keeps the heat more 'omnidirectional', cooking from all sides more evenly. And generally keeps the moisture in.
All evidence of this is from my cooking (on stoves, outdoor grills, campfires) and from what I've picked up from my family and friends. Take it as you will.
Answer 5
I am assuming you are talking about a charcoal grill. When grilling over direct heat, using the lid serves two functions:
First, your food will cook, albeit to a far lesser degree, on the sides that are not facing the coals. Putting the lid on will trap heat in your grill, providing convection as well as direct cooking.
Also, you will be providing less oxygen to your coals with the lid on. This is key in controlling flareups. This is the more important benefit. The biggest risk to ruining your grilled food is the intense heat from flareups on your grill.
