Ever found yourself staring at a whole chicken, wondering exactly how long it’ll take on the grill? I’ve been there! Grilling a whole chicken is one of my favorite weekend cooking activities, but timing it right can be tricky. Whether you’re planning a backyard barbecue or just want a delicious family dinner, knowing the right cooking time makes all the difference between juicy perfection and a disappointing meal.
In this guide, I’ll share everything I’ve learned about grilling whole chickens – from prep to plate. No complicated chef-speak, just straightforward advice that’ll help you nail it every time.
Quick Answer: Grilling Time for Whole Chicken
For those in a hurry here’s the short answer
A whole chicken typically takes about 1 to 1.5 hours to grill at temperatures between 375°F and 450°F. However, this varies based on the chicken’s weight, your grill type, and cooking method
Factors That Affect Grilling Time for Whole Chicken
Several key factors influence how long your chicken will need on the grill:
1. Chicken Size and Weight
The bigger the bird, the longer the cook! Here’s a quick breakdown:
- 3-4 pound chicken: Approximately 60-75 minutes
- 4-5 pound chicken: Approximately 75-90 minutes
- 5+ pounds: 90+ minutes
2. Grill Temperature
Your grill temperature significantly impacts cooking time:
- Higher temps (400-450°F): Faster cooking, crispier skin
- Medium temps (350-400°F): Balanced cooking, good for beginners
- Lower temps (300-350°F): Slower cooking, more smoke flavor
3. Cooking Method
The approach you take matters big time:
- Whole (traditional): 1-1.5 hours
- Spatchcocked (butterflied): 40-50 minutes
- Indirect heat: Usually takes longer but gives more even results
- Direct heat: Faster but risks burning
4. Grill Type
Different grills have different heating characteristics
- Gas grills: Consistent heat, easier temperature control
- Charcoal grills: More variable, adds smoky flavor
- Pellet grills: Great for consistent low and slow cooking
Preparation Methods That Affect Cooking Time
How you prepare your chicken before it hits the grill matters a lot!
Spatchcocking vs. Whole Roasting
Spatchcocking (removing the backbone and flattening the chicken) is a game-changer for grilling time. When you spatchcock a chicken:
- Cooking becomes more even
- Grilling time is reduced by about 30-40%
- The chicken cooks more uniformly
For a 4-pound chicken:
- Whole: 75-90 minutes
- Spatchcocked: 40-50 minutes
I personally prefer spatchcocking whenever I can – it’s worth the little bit of extra prep work!
Marinades and Brining
While marinades and brines add amazing flavor, they can affect cooking time:
- Brined chicken: May cook slightly faster due to better heat conductivity
- Marinated chicken: Similar cooking time to regular chicken
- Stuffed chicken: Adds 15-30 minutes to cooking time
A good Mediterranean-style marinade with olive oil, lemon juice, garlic, and herbs not only flavors the meat but helps achieve that golden, crispy skin we all love.
Step-by-Step Grilling Process and Timing
Let’s break down the whole process with timing:
Setting Up Your Grill (10-15 minutes)
For indirect heat cooking (recommended for whole chicken):
Gas Grill Setup:
- Preheat all burners on high for 10-15 minutes
- Turn off burners on one side (or middle burner in a 3-burner grill)
- Adjust remaining burners to maintain 375-400°F
Charcoal Grill Setup:
- Light charcoal and let burn until covered with ash (15-20 minutes)
- Push coals to one side of the grill
- Place a drip pan on the empty side
Preparing the Chicken (15-20 minutes)
- Remove giblets and trim excess fat
- Season with salt or apply your marinade
- Truss the legs together (for whole chicken) or spatchcock
- Let sit at room temperature for 15 minutes before grilling
Actual Grilling Process
For Whole Chicken (Traditional Method):
- Place chicken on indirect heat side of grill, breast side up
- Close lid and cook for 40 minutes
- Check and rotate chicken for even cooking
- Continue cooking for another 35-50 minutes (depending on size)
- Check internal temperature (should reach 165°F in thickest part of breast)
For Spatchcocked Chicken:
- Place flattened chicken on indirect heat side, skin side up
- Close lid and cook for 20-25 minutes
- Check and rotate if needed
- Continue cooking for another 20-25 minutes
- Check internal temperature (should reach 165°F)
Resting Period (10-15 minutes)
Always, always, ALWAYS let your chicken rest after grilling! This redistributes juices and makes for a moister, more flavorful bird.
How to Tell When Your Chicken is Done
Don’t guess on doneness – it’s too important for both safety and taste!
Using a Meat Thermometer
The most reliable method is using a good meat thermometer:
- Insert into thickest part of thigh without touching bone
- Look for 165°F minimum (I prefer 170°F in the thigh)
- Check multiple spots to ensure even cooking
Visual and Physical Cues
While a thermometer is best, these signs also indicate doneness:
- Clear (not pink) juices when pierced
- Legs move easily in their sockets
- Skin is golden brown and crispy
- Meat feels firm when pressed
Common Mistakes That Affect Grilling Time
I’ve made all these mistakes so you don’t have to!
Grill Temperature Issues
- Starting too cold: Adds unnecessary cooking time
- Too much fluctuation: Leads to uneven cooking
- Too hot: Causes outside to burn before inside cooks
Opening the Lid Too Often
Every time you peek, heat escapes and extends cooking time by 5-10 minutes. Be patient!
Incorrect Placement on Grill
- Placing directly over flames can cause flare-ups and burning
- Not rotating the chicken can result in uneven cooking
Expert Tips for Perfect Timing
After years of grilling whole chickens, here are my top tips:
- Use a good thermometer – Temperature doesn’t lie
- Spatchcock for faster, more even results – Saves time and improves texture
- Angle the thighs toward the heat – Dark meat needs more cooking
- Apply butter under and over the skin – Helps with browning and flavor
- Rest for 10-15 minutes before carving – This is non-negotiable for juicy results!
- Plan for 15-20 minutes per pound as a general rule
- Rotate the chicken halfway through cooking – For even browning

Grilling A Whole Chicken
Once the grill has reached 350˚F, place the chicken on the grill. For gas grills, you will place the chicken over the unlit burner(s) and for the charcoal grill, the chicken will be placed on the opposite side of the charcoal pile. Note: Keep an eye on the temperature and adjust as necessary.
Close the lid and cook for 1 to 1 and 1/2 hours or until an instant read thermometer inserted into the thickest part of the thigh (make sure it isn’t touching the bone) reads 165˚F. Transfer the chicken to a cutting board and allow to rest for 10 minutes before carving. Get a step-by-step guide to perfectly carved chicken.
Oh, no! You forgot to pull the chicken out for the backyard BBQ? Have no fear, you can cook whole chicken from frozen safely. It may not have the grill marks, but it will be tender and juicy and is sure generate some great conversation.
Tips For Whole Grilled Chicken
The secret to perfectly grilled whole chicken is setting up your grill for indirect heat. Much like this roasted chicken recipe, the indirect heat method roasts the chicken to perfect doneness. Because the chicken isn’t over the flames, you won’t have to deal with flare-ups or burnt skin and underdone meat.
One step that I like to take when grilling a whole chicken is to dry brine it for 12-24 hours. Now, this isn’t a requirement but trust me when I say that you will thank me for suggesting it. You can learn more about dry brining over here, but it’s essentially sprinkling salt on meat and then leaving it for awhile. The salt mixes with the moisture from the meat and that salty wetness gets into the meat, making it more flavorful and more tender. You can see how dry brining a whole turkey works as well, which is a great method for Thanksgiving.
I kept the seasonings for this recipe very simple, but I have also included suggestions in the recipe card for some spice and herb combinations that will add some delicious variety to your grilled chicken adventures.
I mentioned that we will be using indirect heat to cook the chicken. This is the secret to eliminating flareups and inconsistently cooked chicken. Essentially, we are replicating how an oven cooks but with all of the benefits of using a grill. Like keeping the kitchen cool during the hot summer months. And let’s face it, it’s fun to cook outside!
To set up your grill for indirect cooking, follow the directions below. Quick note, before you place the chicken on the grilling grate, I do recommend that you place a drip pan under the grate to catch juices and fat that will be rendered during the cooking process. This is a huge help during cleanup.
Three Burner Gas Grill – turn the left and right burners to medium and ignite. Leave the center burner off. Place the drip pan over the non-lit burner under the grate. You’ll place the chicken in the center over the non-lit burner
Four Burner Gas Grill – turn the two left burners to medium and ignite. Leave the two right burners off. Place the drip pan over the non-lit burners under the grate. You’ll place the chicken in the center of the two burners that are off.
Charcoal Grill – light the charcoal using a chimney lighter. Pour the charcoal out of the chimney and push over to one side of the grill. Leave the other side free of coals. Place the drip pan on the non-charcoal side under the grate. You’ll place the chicken on the side of the grill with no charcoal.
