    The chicken cooked perfectly however the juice in the bottom of the slow cooker was not very flavoursome and I don’t think it would’ve been good enough to make a gravy.

    I made this last night for dinner, it was so good! Chicken was so tender it fell off the bone. Grandkids and hubby went back for seconds.

    This is honestly the best and easiest roast chicken, the juice left in slow cooker makes great gravy, I throw some veg in as well, then finish off in air fryer for easy roast dinner 😋

    Absolutely amazing, I put stuffing in mine and it came out just right. Adding other veggies would go well too.

      That’s great to know the stuffing worked well too – thanks Stewart! 🙂

    Cooked the French onion whole chicken last night so moist will definitely doing this again, cheaper than buying a cooked chook from super market and so much tastier, thank you Pauline
    Just a question could you possibly use a different soup just wondering 🤔

    1. Paulene @ Slow Cooker Central June 2, 2026

      Love this feedback! Thanks Colleen 🙂 I don’t see any reason why you couldn’t experiment with other soups too! I’ll try some and let you know too x

    Transforming a basic whole chicken into a culinary masterpiece is effortless when you toss the bird into the slow cooker with the french onion soup mix. It yields tender, fall-off-the-bone meat while magically reducing the juices into a rich, savoury gravy. 😋

    I did the French onion chicken in the slowcooker last night it was delicious. I made gravy with the juices I added gravy powder stirred it in and left the slowcooker on for a further 10mins for the gravy to thicken after I took the chicken out.

    Very simple to do, tastes absolutely delicious, I used 4 very large chicken Marylands and one packet of French Onion Soup, which was more than enough to coat the 4 pieces, no water, popped the lid on and let my SC do its magic.

      So wonderful to hear you enjoyed it! And thanks so much for coming back and leaving your feedback – we so appreciate that 🙂

    The chicken was so moist and the pan juices made the most delicious gravy.

    This is a new fav in our house! Kids lick the plates clean every time. We swap the whole chicken for drumsticks, just a personal preference. It tastes amazing every time! I even started telling people the recipe, so simple and too easy!!

    1. Paulene @ Slow Cooker Central June 26, 2026

      What a magical feedback to start my day with!! Thanks so much Dayle 🙂 🙂

    Tried this for the first time and it won’t be the last, served with roast veg and used left overs on wraps.

    I made this chicken in the slow cooker, and it turned out absolutely amazing! It was incredibly tender, juicy, and full of flavour. The meat was falling off the bone and stayed so moist. My whole family loved it. I’ll definitely be making this recipe again. Highly recommended it

    1. Paulene @ Slow Cooker Central July 24, 2026

      That’s some incredibly awesome feedback!! Thank so much 🙂 🙂
