This crockpot whole chicken recipe is a true gem among my collection, delivering the perfect blend of speed, simplicity, and a classic Roast Chicken experience without any compromise. Here’s why it stands out:

  • The chicken’s flesh, including the breast, turns out remarkably juicy, as if it has been expertly brined;
  • Remarkably forgiving – Even if you accidentally extend the cook time by 2 hours, the chicken remains succulent, all thanks to the magic of slow cookers!
  • The end result looks and tastes just like a traditionally oven-roasted chicken, with the added surprise that the breast meat is even more tender and juicier;
  • You have the flexibility of choosing various cooking options with the same outstanding outcome. Opt for slow cooking on low (5 hours) or high (3 hours), or speed things up with pressure cooking for 24 minutes.
  • You’ll be thrilled to know that it takes less than 10 minutes to prepare the chicken before it goes into the slow cooker, and you can even prep ahead. Additionally, the Lemon Sauce is a breeze to make – just add cornflour/cornstarch to the slow cooker juices.

How to Cook a Whole Chicken in a Slow Cooker

This delectable Lemon Garlic slow cooker whole chicken starts with a flavorful olive oil paste, crafted with zesty lemon, garlic, salt, pepper, and your preferred dried herbs (like thyme, oregano, and parsley).

To infuse the chicken with maximum taste, most of the paste is gently spread under the skin. Don’t worry about perfection; it’s an easy process! You can follow along with the video to see how it’s done. Simply use a dessert spoon to loosen the skin, carefully spoon the paste underneath, and then spread it roughly using your hands or the spoon from the outside. As the chicken cooks, the paste will naturally spread and slide.

For added aroma and moisture, tuck a used lemon inside the chicken before placing it on a rack in the slow cooker. If you don’t have a rack, you can use balls or create a ring of scrunched up foil to lift the chicken off the bottom.

Let it slow cook for 5 hours on low, and when it’s ready to come out of the slow cooker, you’ll be greeted by an enticing aroma. However, the chicken’s appearance might seem unappealing at first – pale and colorless. No worries, though! A quick 5 to 10 minutes under the broiler/grill will work wonders. You’ll be amazed at how rapidly the skin transforms from bland to crispy golden brown, adding the perfect finishing touch to this delightful dish!

How long does a whole chicken take in the slow cooker?

For a 2kg/4lb whole chicken, you have two cooking options to achieve different results:

  1. For a juicy and carvable chicken similar to a traditional oven Roast Chicken:
    • Cook on low for 5 hours, or
    • Cook on high for 3 hours.
  2. For exceptionally tender meat that easily pulls off the bone:
    • Slow cook on low for 7 to 8 hours.

Choose the cooking time that best suits your preference, and enjoy a deliciously cooked whole chicken with either option!

Pressure Cooker / Instant Pot Option!

Absolutely! This versatile Lemon Garlic Roast Chicken can be prepared using a pressure cooker as well, and the result is just as delightful as the slow cooker version, but with the added bonus of being much quicker. Here’s how to do it:

  1. Add 1/2 cup of water to the pressure cooker.
  2. Place the prepared whole chicken into the pressure cooker.
  3. Pressure cook for 24 minutes on high.
  4. After cooking, allow the pressure to release naturally for 10 minutes.
  5. Finally, release the pressure valve to complete the cooking process.

In no time, you’ll have a succulent and flavorful Lemon Garlic Roast Chicken that’s perfectly cooked and ready to be enjoyed!

Lemon Sauce 

Initially, I referred to this sauce as a gravy, but the idea of a lemon-flavored gravy felt a bit unusual. So, I decided to simply call it Lemon Sauce!

You’ll appreciate how remarkably simple this sauce is compared to traditional gravies. No need to deal with greasy pans, cooking flour, or straining. All you have to do is add cornstarch / cornflour and let it simmer until it thickens. That’s all there is to it! It’s a hassle-free way to achieve a delightful Lemon Sauce that perfectly complements your dish.

Oh the possibilities!!!

The beauty of recipes like this Slow Cooker Roast Chicken lies in their adaptability, allowing you to put your personal touch on the dish. While I’ve kept it straightforward as an everyday roast chicken recipe, there are plenty of ways you can customize it to suit your preferences. Here are some ideas for variations:

  1. Experiment with different dried herbs or use fresh herbs instead of dried ones for a burst of flavor.
  2. Add your favorite spices or opt for a rub instead of using herbs.
  3. Enhance the flavors by placing a quartered onion and halved head of garlic (or smashed garlic cloves) under the chicken. This will add extra richness to the sauce, which can be strained out later.
  4. Infuse the chicken with more flavor by stuffing it with fresh herbs and a halved head of garlic. To ensure a strong garlic taste, use a generous amount of garlic.
  5. Substitute oil with butter for an even richer taste (use a larger quantity of butter).

Feel free to get creative and make this recipe uniquely yours! The possibilities are endless. I’m excited to hear your feedback and learn about the creative ways you make this Slow Cooker Roast Chicken your own. Enjoy experimenting and happy cooking!

  • 2 kg / 4 lb whole chicken , patted dry (Note 1)

  • RUB (NOTE 2):

  • 1 tsp dried thyme

  • 1/2 tsp dried parsley

  • 1/2 tsp dried oregano

  • 3/4 tsp salt

  • 1/2 tsp black pepper

  • 2.5 tbsp olive oil (or melted butter), plus extra for drizzling

  • 3 garlic cloves , minced

  • 1 large lemon , all zest + all juice


  • 1 tbsp cornflour/cornstarch mixed with 1 tbsp water

  • 1 extra lemon , just in case


Prepare the Rub by mixing its ingredients. The consistency should be fairly thick and sludgy. If it's too thick, add extra oil to adjust.
Loosen the skin of the chicken using an upside-down spoon (see the video for reference). Spread most of the Rub under the skin, leaving about 1 tablespoon of mostly oil for the skin. Use your hands or a spoon to spread the paste on the skin – it doesn't need to be perfect.
Insert the used lemon inside the chicken.
Place a rack inside the slow cooker (refer to Note 3), and position the chicken on top. Spread the remaining Rub on the chicken, then sprinkle with a pinch of salt and pepper.
Slow cook the chicken for 5 hours on low or 3 hours on high. Alternatively, continue cooking until the juices run clear or the internal temperature reaches 75°C / 165°F (using a meat thermometer). (Note 4 for other cooking methods)
Once done, remove the chicken from the slow cooker, drizzle with a bit of extra oil, and grill/broil on medium-high heat for 5 to 10 minutes to brown the skin (approximately 25cm / 10" from the heat source). Alternatively, you can use the oven at 240°C / 450°F for 10 minutes.
Spoon the pan juices over the chicken, then serve it with the delightful Lemon Sauce. No need to rest the chicken.

For the Lemon Sauce:

Pour all the liquid from the slow cooker into a saucepan, and add the cornflour / water mixture. Mix well.
Bring the mixture to a simmer over medium-high heat, and cook until the liquid thickens to a thin syrup (usually around 3 minutes, depending on the amount of liquid). Adjust the seasoning with salt and pepper to taste, and if desired, add more lemon for extra flavor. Pour the sauce into a jug for serving. Enjoy!


Begin by preparing the chicken - ensure to remove giblets or any other internal parts. If the chicken is frozen, make sure to thaw it completely. Refer to the cook times below based on different weights. Regarding herbs, you have several options: You can substitute with other dried herbs of your choice, or you can use finely chopped fresh herbs, doubling the quantity. Another option is to stuff a bunch of herbs inside the chicken for added flavor. If you don't have a rack, you can create an alternative by using a large sheet of foil scrunched into a "rope" and formed into a ring. Alternatively, use four balls of foil to elevate the chicken, ensuring it's out of the liquids produced during cooking. You can also try different cooking methods. For pressure cooking, add ½ cup of water and cook for 24 minutes on high pressure. Depressurize naturally for 10 minutes before releasing the valve. For oven cooking, follow the directions in the juicy Roast Chicken recipe. Here are the Slow Cooker Cook Times based on chicken weight: 1-1.5kg / 2-3 lb: 4.5 hrs on low 1.75-2.25kg / 3.5-4.5 lb: 5 hrs on low 2.5kg / 5lb: 6 hrs on low For meat that easily falls apart, add 1 to 2 hours onto the cook times. The flesh will still remain juicy! Prep Ahead / Storage: You can prepare the chicken with the rub under and on the skin and refrigerate it for up to 48 hours. Then, slow cook it per the recipe. Cooked chicken can be stored in the fridge for 3 to 4 days. The provided nutrition per serving assumes that all the sauce is consumed. Feel free to experiment with these guidelines, and make the recipe your own! Enjoy the cooking process, and the resulting delicious Lemon Garlic Roast Chicken!
