Ingredients

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

  • 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

Lemon Sauce:

  • 1 tbsp cornflour/cornstarch mixed with 1 tbsp water
  • 1 extra lemon , just in case

Instructions

  • Rub – Mix Rub ingredients. should be fairly thick and sludgy. Adjust with extra oil if too thick.
  • Loosen Skin: Use upside spoon to loosen skin of chicken (see video). Spoon most of the Rub under the skin, leaving about 1 tbsp mostly oil for the skin. Use hands or spoon on skin to spread the paste - doesn't need to be perfect.
  • Stuff used lemon inside the chicken. 
  • Put rack inside slow cooker (Note 3), place chicken on top. Spread with remaining sludge, sprinkle with a pinch of salt and pepper.
  • Slow cook 5 hours on low or 3 hours on high, or until juices run clear or internal temperature is 75C / 165F using a meat thermometer. (Note 4 for other cook methods)
  • Brown skin: Remove chicken from slow cooker, drizzle with a bit of extra oil. Grill/broil on medium high for 5 to 10 minutes to brown the skin (~25cm /10" from heat source). Or oven 240C/450F for 10 min.
  • Spoon over pan juices, then serve with Lemon Sauce! (No need to rest chicken)

Lemon Sauce:

  • Pour all slow cooker liquid into a saucepan, add cornflour / water mixture. Mix.
  • Bring to simmer over medium high and cook until liquid thickens to thin syrup (depends how much liquid you have, usually 3 min or so). Adjust salt and pepper to taste, add more lemon if desired (the extra lemon). Pour into jug.

Notes

1. Chicken - Remove giblets or anything else inside. If frozen, thaw completely. See below for cook times for different weights.
2. Herbs - can sub with other dried herbs of choice OR use finely chopped fresh but double quantity. Can also stuff a bunch of herbs inside!
3. Alternative to rack - use big sheet foil, scrunch into “rope” then form ring. Or 4 balls of foil. Aim is to elevate chicken out of liquids that it produces while cooking.
4. Other Cook Methods:
Pressure cook - Add ½ cup water and pressure cook for 24 minutes on high (depressure naturally 10 min before releasing valve).
Oven - Follow directions in this juicy Roast Chicken recipe.
5. Slow Cooker Cook Times: 
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 almost "all apart" meat, add 1 to 2 hours onto the cook times. Flesh is still juicy!
Pressure Cooker: 6 minutes per 500g/1lb of chicken.
5. Prep Ahead / Storage: Prepare chicken with rub under and on skin. Refrigerate up to 48 hours then slow cook per recipe. Cooked chicken keeps for 3 to 4 days in the fridge.
6. Nutrition per serving assumes all sauce is consumed.
