How do you cook a Whole Roast Chicken in the Slow Cooker?
Firstly, technically this isn’t a ‘roast‘ chicken. But, I tend to call any whole joint of meat a ‘roast’ so it seems fitting, right?
I like to make a simple herby butter, spread it over the meat, pop into the slow cooker (or crock pot) and cook until everything is soft, delicious and tender.
You can then remove the skin and serve like this if you’re happy to. (I remove the skin if serving like this, as the meat won’t look very pretty at this stage as it hasn’t been browned.)
What about crispy skin when you cook it in the slow cooker?
If you do want to serve the whole bird, just pop it under a hot grill (broiler) for about 10 minutes until the skin is crispy and golden and delicious.
Taa daaa best of both worlds! Soft, tender meat and crispy skin.
How do I make gravy for my Slow Cooker Whole Chicken Roast?
If you want to serve gravy with your Roast Chicken, once you remove the chicken from the tin, blend the onions into the liquid (if you have a blender, if not, leave them in whole or remove with a slotted spoon if you prefer your gravy smooth).
Put 2 tbsp of cornflour into a small mug and add enough of the chicken juices to make a smooth paste.
Put the chicken juices over a medium heat on the hob (in the slow cooker pan, if it’s heatproof and suitable for use on the hob, or in a small saucepan) add in enough of the cornflour mixture, a little at a time, whisking as you go to thicken the liquid.
You may not need to use all of the cornflour mixture, depending on how much liquid your chicken has released as it cooked.

Slow Cooker Whole Roast Chicken
Ingredients
For the herb butter
- 3 tbsp Butter See note 1.
- 1 tbsp Fresh thyme Leaves only, stalks removed
- 1 tbsp Fresh sage Finely chopped
- 1 tbsp Garlic powder
- Salt and freshly ground black pepper
Instructions
- Mix the herb butter ingredients together.
- Pop the onion chunks into the bottom of the slow cooker and set the chicken on top. (I like to cut off and remove and string holding the bird. I think this makes it cook more evenly.)
- Spread the herb butter over the top and sides of the chicken.
- Slice one of the lemons in half and push in around the edges of the bird. Add 100ml of boiling water. Pop the lid on and cook for about 5 hours on LOW.
- The chicken is cooked when if you wiggle a leg bone, it feels very loose. You can now serve (I tend to remove the skin and portion up if serving like this as the skin doesn't look/taste very good.) OR if you'd prefer to serve as a regular whole bird roast:
To brown the chicken
- Pop the whole chicken under a very hot grill for about 15 minutes until the skin is crunchy and crisp. Add more lemon slices and fresh herbs to serve if you'd like to.
