Whole Chicken in the Slow Cooker (Ranch & Onion)

A whole chicken, two packets of seasoning, and absolutely no liquid, just the fat that renders from the bird itself. It sounds mad, but this no-fuss slow cooker method actually works, turning out a juicy bird in six hours flat.

How to cook a whole chicken in the crockpot!

Source video by YouTube on YouTube. This recipe was adapted with strict source-fidelity rules and is marked for human review.

This is a no-fuss whole chicken cooked in the slow cooker with absolutely no added liquid. The chicken sits on a bed of carrots, potatoes and onion, which lifts it off the base and adds gentle flavour as it cooks. A packet of ranch seasoning and a packet of onion soup mix is patted all over the bird before it goes on high for around six hours. The chicken comes out moist and fully cooked, with juices and fat collecting at the base of the pot.

Editor's note: No quantities stated for the chicken weight, carrots, potatoes or onion (cook only describes 'a thin layer' of veg at the bottom). Servings estimated from a typical whole chicken; not stated in source. Ranch and onion soup mix quantities are explicit (1 packet each). Cook says 'almost six and a half hours on high' but instructed six hours on high at the start; six hours is used. | Second-pass critique flagged 2 fabricated and 7 quantified issues.

Method

  1. Scatter a thin layer of carrots, baby potatoes and onion across the base of the slow cooker.

    ~5 min

  2. Sit the whole chicken on top of the vegetables.

    ~1 min

  3. Tip the packet of onion soup mix over the chicken and pat it all over the skin to coat.

    ~2 min

  4. Tip the packet of ranch seasoning over the chicken and pat it in so the bird is coated all over.

Frequently asked

Do I really not need to add any liquid?
No. The chicken releases plenty of fat and juice as it cooks, and the bed of vegetables stops it catching on the base. By the end there will be a good pool of liquid in the pot.
How do I know the chicken is cooked through?
Pierce the thickest part of the thigh: the juices should run clear, and the leg should pull away easily. A probe thermometer in the thickest part of the thigh should read at least 75°C.
Can I cook it on Low instead?
Yes, around 7 to 8 hours on Low is a typical equivalent for a whole chicken, but check it is fully cooked through before serving. The recipe as filmed uses 6 hours on High.
Will the skin be crispy?
No. Slow cookers steam rather than roast, so the skin stays soft. If you want crispy skin, lift the cooked chicken onto a tray and pop it under a hot grill for a few minutes at the end.
Can I brown the chicken first?
You can, and it will deepen the colour and flavour, but it is not needed for this recipe. The ranch and onion soup mix give the bird plenty of seasoning on their own.
