1/2 tsp curry powder (extra if you prefer more heat)
1 x 40g sachet of dry French onion soup mix
Optional: 1T cornflour + 1T water
Instructions
Place chicken and onion in slow cooker
Combine all other ingredients and pour over chicken
Cover with tea towel trick and cook on low for approx. 4hrs.
If yours requires extra thickening at the end, you can stir through a slurry of 1T cornflour mixed with 1T tap water in the final 10mins to thicken the sauce further, however ours did not need this.
