    Can it be cooked on low for 8-9 hours?

      Hi, Elena. If you cook it for that long, it will become mush and be very unpleasant. Thanks for visiting our online home. 🙂

    Valya, i noticed you use a different type of seasoning for this dish and for the one you bake in the oven. Can you please explain why? Thank you!

      Hi Jessica,
      I always get so excited when our readers (our online family) notice little things like that. Makes me oh so happy. 🙂
      You can use either seasoning. I just wanted it to have its own taste, one that is a little different than the baked one. Hope you love this recipe as much as we did!

    Did you say 5 hours on slow AND 3-4 hours on high? Or it is suppose to be OR? Either or? Please verify, i do not cook in a slow cooker, but have one and would like to try. Preassure cooker cooks everything fast. I use it to have soup in 20 minutes on the table. 10 minuts – prep, 10 minuts- cook under pressure and any soup with meat is ready on the table. I like my pressure cooker!

      Hi Natash,
      Sorry for confusing you. I’ll have to fix that. 3/4 on high OR 5 hours on low. Can you believe it, I don’t even own a pressure 11cooker. I’m reviewing them now, looking to purchase one and get started cooking☺. What brand do you have? Do you like it?.

    Holy delish. This looks absolutely amazing, and I adore how simple it is. Slow cookers save lives!

    will this work in a pressure cooker?

    • admin 03/23/2017, 1:54 am Link Reply

      Please don’t judge me – I have yet to try cooking in a pressure cooker (yes, cheeks blushing). It is on my to-do list. I don’t see why it wouldn’t work, except I have no idea for how long. If you try it, I’d love to hear feedback. 🙂
