Ingredients

  • 1.5 kg Free range whole chicken
  • 1 Onion Peeled and cut into large chunks
  • 2 Whole lemons

For the herb butter:

  • 3 tbsp Butter See notes
  • 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.

Notes

Butter: I use salted butter, if you only had unsalted, you could add extra salt. The butter should be soft, but not melted. If it's hard, just pop into the microwave for a few seconds
Herbs: You can use dried herbs if you prefer and/or it's all you have, BUT in this case I do feel like fresh herbs do work best as they have a more aromatic, softer quality
To get a crispy skin: The chicken won’t get that crispy or golden skin we associate with a roast, but simply cutting it off after cooking is fine - it’s still delicious. However, if you DO want a crispy skin, just pop it under the grill for about 10-15 minutes until it crisps up and turns colour
Water: When it comes to making a roast chicken, there are plenty of its own juices that stop it from drying out. So just using about 100ml in the bottom of the cooker is sufficient
Make a gravy:
  1. Once you remove the chicken from the cooker, 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).
  2. Put 2 tbsp of cornflour into a small mug and add enough of the chicken juices to make a smooth paste.
  3. 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 if not).
  4.  Add in enough of the cornflour mixture, a little at a time, whisking as you go to thicken the liquid.
