    Hi Pauline, if I double the beef, do I double all the ingredients please? Thankyou

      Hi Debbie, you most likely won’t need to double the sauce as it does make a fair bit. However if you want to, double everything except the french onion soup (or that get’s too salty if doubled) 🙂

    This recipe doesn’t disappoint, I used chuck steak and it turned out so tender.

    Hi Paulene I have about a kg of round steak so will give this a bash but we looove mushrooms so can I add them in as well?

    1. Paulene @ Slow Cooker Central August 11, 2026

      You sure can add mushrooms Doris 🙂
      Just keep in mine it’ll also add a bit of water with them so may need a little thickening at the end potentially

    Hi all, with the help of the amazing Paulene, we were able to adapt this recipe to a low salt version. We subsitiuted the mushroom soup for a bottle of cooking cream and approx 200g of blitzed mushrooms. 1 massell beef stock cube, 1 packet of reduced salt french onion soup, still trying to find the reduced salt cubes and we halved the worsteshire sauce.
    Much appreciated.

    Made this beef obsession yesterday with oyster blade steak. I have made with lamb also and it’s absolutely delicious. It’s quick and easy to throw together takes no time at all I served with creamy mash potato, green beans and corn on the cob. Do yourself a favour and give it a go you won’t be disappointed 😋
