  1. I’ve been thinking of cooking in foil since so long but couldnt decide which recipe. I do have Halibut at home and looks like this would be a great weekend brunch.5 stars

  2. There’s nothing better than dishes with few ingredients, easy to make, that taste great! Love the way the halibut stays juicy and soft in the foil packet.

  3. This fish looks so good. I really like that you used the foil packet to keep the fish moist. Adding the butter and rosemary is another great layer of flavor. Delicious!

  4. Sometimes the simplest recipes are the best! It doesn’t alway have to complicated with lots of ingredients. I love the flavors in this dish!5 stars

  5. I do not “do dairy”, can I just leave out the yogurt— or use butter………??

    thanks! sounds easy and yum!

    1. Ya, you could use butter / ghee, or even a non-dairy yogurt. I haven’t tried a non-dairy yogurt but I’d be curious how that would taste. 🙂

  6. Isn’t it so fun to look back at our first posts on our blogs? I’ve been redoing recipes too, very time-consuming! Either way, this halibut looks really delicious and succulent! Not dry in the least bit, which is perfect!! I will be making this as soon as I can pick up some halibut!5 stars

    1. It is fun to see how far we’ve come! Blogging has changed so much in the last few years, it’s hard to keep up!

  7. Super filling, vitamin b, omega 3 and protein. #yum…

    also …”It’s all a part of the never-ending list of things that I want to get done before “OUR” baby arrives. Haha.

  8. My mother used to cook half of a salmon in a foil pouch, but instead of the healthy Greek Yogurt, she used butter. It was so good, and delicious over rice or veggies. YUM! I can’t wait to give your recipe a try. I really love foil pouch meals during the summer, but I throw them on the top rack of the grill instead of the oven.

    I know what you are saying about updating old posts. I plan to start doing that later this year. I’m still working on my photography, and am nowhere near as good as you are, but I’m so much better than I was in the beginning. Congratulations on your new little bundle of joy.

    1. I love the idea to cook them on the grill! And I also love the sound of salmon and butter… drool!

      Updating posts is quite a bit of work, but I think worth it in the end. I hope! haha Thank you! 🙂
