Grilled Seabass with Lemon Garlic Butter Sauce and Colcannon

Grilled Seabass with Lemon Garlic Butter Sauce and Colcannon - Fab Food 4 All If I asked you where all the ingredients for this Grilled Seabass with Lemon Garlic Butter and Colcannon came from I’ll bet not many of you would say Iceland but that’s exactly where I bought them! Having been challenged to “Go Frozen with Iceland” I couldn’t wait to visit my nearest store and see what was new as I have to admit I hadn’t been in a while! The #PowerofFrozen message is all about telling consumers that not only is Iceland food about convenience and waste/cost saving but with advanced freezing techniques it’s also about locking in the natural flavours and nutrients.

I wasn’t sure what I was going to make when I ventured into Iceland but as soon as I walked up the first aisle the gorgeous bags of frozen Seabass just called out to me. I can’t remember ever seeing frozen Seabass for sale and I’ve never bought it fresh as it’s usually so expensive! I decided to walk around the rest of the store looking for inspiration and pondered over the Crocodile Burgers and the Ostrich Fillets which I was very surprised to see! Delving deeper into the store I was very happy to come across frozen Kale which again I’d never seen and being a big Kale fan I suddenly knew what dish I was going to make! One of my favourite dishes I’ve eaten out in the past is Grilled Seabass with a Pea Mash so I based my idea loosely around this. I knew frozen mash was a thing and it wasn’t long before I came across frozen onions so these were the ingredients I needed for my Colcannon. Amongst the boxes of frozen herbs I found chopped garlic for my sauce which I would pair with lemon and butter (both also available in Iceland but I already had these at home).

I couldn’t wait to get home and create my restaurant style meal. The whole family loved this Grilled Seabass with Lemon Garlic Butter Sauce and hubby was really impressed and couldn’t believe that I’d made the meal with just ingredients from Iceland. In fact he have me 9.5 out of 10. I lost half a point as his plate was the one in the photograph so wasn’t quite as hot as it could have been! (Don’t marry a food blogger if you want hot dinners)! I have to say I was very pleased as the whole meal was so easy to prepare and ready in half an hour plus good enough to entertain with! I’ll be going back to Iceland next week as I want to explore the luscious looking speciality breads/pastries as well as the fruits and gelato that I saw but knew I had no more room in the freezer!

    I have never cooked with sea bass but I do love this fish. Great recipe.

    1. Camilla

      I hadn’t either but so easy using Iceland’s seabass:-)

  2. glenn hutton

    We don’t eat enough fish in our household but this looks amazing! 🙂

    1. Camilla

      Thanks Glenn, do try try to eat a portion of oily and white fish each week for good health:-)

  3. Jayne Sullivan

    This looks amazing. I have been wanting to try Sea Bass for a while. I was not sure how to cook it.

    1. Camilla

      Thanks Jayne:-)

  4. Sharon Jackson

    I wish I could grab this dish out of my screen, it looks absolutely delicious. I love fish. Oh boy it looks amazing, wish mine would look as good as that 🙂

    1. Camilla

      Thanks Sharon, I’m sure you could recreate this dish, not difficult:-)

  5. Kavey

    Had heard from another friend that Iceland are great for meat, particularly game and so-called exotic meats, but hadn’t really thought about fish. That’s great news as no decent fishmonger near me (or butcher for that matter).

    1. Camilla

      Yes I even saw crocodile burgers in there Kavey! The Seabass was excellent:-)

  6. Heather Haigh

    This is making my mouth water, it looks and sounds so delicious.

    1. Camilla

      Thanks Heather, it was fab;-)

  7. christine

    Beautiful. Certainly looks like a restaurant dish. I have never prepared seabass, it looks lovely.

    1. Camilla

      Thanks Christine, I hadn’t prepared one either but had enjoyed when eating out:-)

  8. KC the Kitchen Chopper

    What a fantastic feast. Love all the Kale in the colcannon. YUM!

    1. Camilla

      Thanks KC, went down well here:-)

  9. Heidi Roberts

    This looks really appetizing – I don’t cook fish at home as much as I should – usually just order it in a restaurant. I love that you can now get kale frozen too – might try growing it on the allotment this year.

    1. Camilla

      Thanks Heidi-)


    I cant believe all that came from frozen! I think I need use frozen more!

    1. Camilla

      It’s so brilliantly convenient and quick and did I mention delicious:-) I was back in Iceland this week and we had their chocolate gelato tonight which was good:-)

  11. Debra @ Bowl Me Over

    This looks so delicious, just perfectly done. Loving that lemon sauce too – what a fun outing for you!

    1. Camilla

      Thank you Debra, yes it was great getting to know all the new food in Iceland, I was even back there today:-)

  12. munchies and munchkins

    I went into Iceland at Christmas for prosecco and it was the first time in about 10 years. I was so impressed by all of the new lines and it was a complete change to what I remember. This dish looks amazing – I rarely eat fish but this looks so appetising.

    1. Camilla

      Thank you Becky, yes it had all changed since I was last there too:-)

  13. peter @feedyoursoultoo

    I am focused on the fish – nice and light with a rich sauce.

    1. Camilla

      Thanks Peter, the Seabass was the star of the show:-)

  14. Choclette

    Ooh that Colcannon looks delicious Camilla. Pure comfort food and so easy too with all those goodies from Iceland. I too was impressed with the kale and other veg and herbs on offer.

    1. Camilla

      Thanks Choclette, yes I think I want to keep frozen mash and kale as a permanent fixture in my freezer now as so convenient:-)

  15. Tara

    This meal sure looks amazing, perfect for the spring weather we are having now!!

    1. Camilla

      Thanks Tara, here in the UK it’s so cold, spring hasn’t sprung yet! But the sun is out today so that’s a start:-)

  16. Kavey

    Lovely, I do love seabass, such a lovely fish. Need to cook with it more.

    1. Camilla

      Thanks Kavey:-)

  17. Katie Bryson

    What a glorious dish Camilla… right up my street. I never shop in Iceland, but I think I need to open my mind and get myself down there. I’m a huge fan of frozen food, so it makes total sense!

    1. Camilla

      Yes Katie, we both have connection with Birds Eye (mine in the past) so we don’t need to be told how fab frozen food is;-) In fact I’m sure there are people out there who received a fact sheet about frozen food when they were students written by me back in the 90’s!

  18. Del's cooking twist

    I love sea bass and this dish sounds wonderful!

    1. Camilla

      Thank you Del, it was fabulous:-)

  19. Patty Haxton Anderson

    My husband fishes for Atlantic Sea Bass – we can’t wait till the season begins!

    1. Camilla

      Wow that’s so cool Patty:-)

  20. Helen @ family-friends-food.com

    Seabass is a thing I usually have in my freezer! I like to keep fish ‘in stock’ as it makes such a quick and easy meal. Your sauce looks gorgeous – so creamy and unctuous – I’ll have to give it a go next time I thaw out some seabass 🙂

    1. Camilla

      Thanks Helen! I didn’t thaw out my seabass even though some comments on Iceland’s website mentioned doing so. I just followed the instructions on the pack and the Seabass cooked great from frozen under a medium grill:-)

  21. Diana

    I love seabass, but my husband doesn’t eat fish so I don’t eat it as often as I used to (before I got married). A lemon garlic sauce sounds amazing though, I will have to try this sometime 🙂 And I love Iceland, it was a surprise to find frozen sushi and frozen curly kale in there! Thanks for linking to my post

    1. Camilla

      Thanks Diana, yes I’m off to Iceland again on Thursday as have an appointment nearby:-)

  22. Emma

    I’m amazed by the variety of produce at Iceland I really had no idea! I just thought it was all baked bean pizzas and chicken tikka lasagne. This looks fantastic though. Definitely something I’d make for myself! Great job!

    1. Camilla

      Aaw, thank you Emma, yes my hubby was gobsmacked for want of a better word when I told him this meal was made with ingredients from Iceland:-)

  23. Corina

    Seabass is one of my favourite fish and it’s just gorgeous in a lemon butter sauce! It’s my husband’s favourite way to eat fish.

    1. Camilla

      I love it too Corina and will be having it at home now I’ve discovered this find in Iceland:-)

  24. kellie@foodtoglow

    This recipe is fabulous, Camilla. Although we mainly eat vegetarian and vegan these days, I feel better having some fish in my diet too so this looks wonderful to me.. Discovering the huge selection of MSC approved frozen fish at Iceland has been an eye-opener – as has been those big bags of kale!

    1. Camilla

      Thanks Kellie, yes I can’t wait to try some more of their fish now as I was very impressed with this Seabass and the kale will be a regular fixture too!
