As a junior product tester just starting my career, I was thrilled to get the opportunity to test various grills. Picture this: an entire week dedicated solely to grilling. On my first day, I spent hours setting up a gleaming line of grills. However, as I prepared to cook my first test meal, I realized I lacked a systematic approach to grilling. While I had grilled chicken countless times, I was unfamiliar with the actual science behind whether to grill with the lid on or off.
Fortunately, after years of experience testing top grills and conversing with professionals in kitchens and barbecue pits nationwide, I've learned a straightforward principle.
The key rule is to think about it as if you’re cooking in an oven. If it seems like you’d bake the dish, keep the grill lid closed. Conversely, if you would typically fry it in a pan, then grill with the lid open.
When is it Best to Grill with the Lid Closed?
You should keep the grill lid closed when cooking items that require more than 30 minutes. For instance, a whole chicken typically takes about an hour to cook, so you should use indirect heat and close the lid.
The reason for this is that closing the lid creates an oven-like environment within the grill. Rather than allowing hot air to escape, it circulates around your food, cooking it from all sides rather than just the bottom.
This technique also helps retain moisture, preventing your ingredients from drying out and ensuring that whatever you’re grilling remains juicy and delicious.
Chef Alfredo Nogueira mentioned, "I own a classic Weber kettle grill and prefer to set up a two-zone cooking area with coals on one side and nothing on the other. Often, I’ll cook a whole spatchcocked chicken or a thick steak on the side without coals while keeping the lid on."
Alfredo “Fredo” Nogueira is the Chef-Partner at Cane & Table, a Cuban-meets-Cajun restaurant and bar in New Orleans’ historic French Quarter.
When Should I Grill with the Lid Open?
When cooking quickly over high heat, you should grill with the lid open. This method is ideal for classic grill favorites such as beef burgers, hot dogs, chicken legs, or vegetarian options like halloumi, grilled asparagus, or vegetable skewers.
The primary goal when grilling burgers and other fast-cooking foods is to achieve a sear on the outside. A sear occurs due to the 'Maillard reaction,' which takes place when meat is exposed to direct heat at temperatures exceeding 280°F. This reaction is responsible for the rich, caramelized flavors in your food.
Given how hot this temperature is and the speed of the reaction, cooking with the lid closed becomes unnecessary. Foods like burgers, which require turning occasionally, would only lead to opening and closing the lid frequently, negating the advantages of trapping air, moisture, and smoke. Grilling at this high temperature will also ensure the insides of your food cook properly, making the lid unnecessary.
Chef Alfredo Nogueira shared, "Grill with the lid open when cooking directly over the fire. Think high heat and quick cooking that demands close attention, such as thin burgers, shrimp, or blanched vegetables that you want to lightly char."

This remains the best grill I’ve ever tried. It’s straightforward, efficient, and produces the tastiest food of all the grills I’ve tested.
Best kamado
Kamado Joe II
The best sears I’ve encountered have come from kamado grills like this one, and the Joe II is particularly effective, although it is on the pricier side.
What If My Grill Lacks a Lid?
If your grill doesn’t have a lid, cooking large cuts of meat becomes challenging. While it can be done in theory, my experience suggests that the results will often be dry or undercooked, raising health concerns.
For smaller items, aluminum foil can be a helpful tool. While it won’t work as effectively as a lid, you can wrap fish and smaller cuts of meat, like chicken wings, in foil to achieve some of the benefits of closing the lid. However, keep in mind that it won’t be as effective. For instance, grilling salmon will have limited convection around the fish, compared to grilling it without any foil.
Grilling FAQs
What’s the Difference Between Indirect and Direct Heat?
In grilling terms, direct heat refers to cooking directly above a flame or hot coals, while indirect heat means using residual heat around your ingredients. For example, grill a burger directly over hot coals, but when grilling a whole chicken, light a fire at one end of the grill and place the chicken at the other end to prevent burning.
