I’m pretty sure canned pre-cooked fish was one of the greatest food inventions besides sliced bread. Anyone else agree? So easy, affordable, and nutritious! And yummy too – Zara agrees. Days where I eat canned fish for lunch are her FAVORITE days. :)

I’m assuming you guys are probably already canned tuna and salmon fans (psst: try my Easy Salmon Brown Rice Cakes recipe), but have you given sardines a shot yet? They look gross but taste good, I promise. :)

And they are good for you, too! Eating seafood, which includes fish and shellfish, at least two times per week (as recommended by the 2015-2020 US Dietary Guidelines for Americans) will reap plenty of nutritional benefits. Seafood is not only high in protein, but also a great source of Omega-3 fatty acids, which support heart health and brain development and reduce inflammation.

And as far as fish goes, sardines in particular are nutritional superstars! They are high in omega-3’s, contain virtually no mercury and are loaded with calcium (because of the tiny edible bones in the fish – a fun fact to gross people out with). They also contain B vitamins, iron, magnesium, phosphorus, potassium, zinc, copper and manganese – and they’re super cheap AND shelf stable. Total win, right?

I usually buy sardines packed in water and add my own sauce to the mix, either mixed in with the sardines or as a spread on the sandwich or wrap I’m having with the sardines. In the case of this recipe, simply mix together some plain yogurt and dijon mustard to create a creamy, tangy spread.

Hot tip: regular bread works fine here (just be sure to toast it), but this recipe is especially delicious if you use European-style rye bread – the really dense, thin, seedy bread! It’s nice and sturdy and perfect for open faced sandwiches, and helps the bread to not get soggy if you pack this to go.

Once your dijon-yogurt sauce is on the bread, layer on some lettuce, cucumbers, sliced hard boiled eggs, and red onion.

And finally, add your sardines! Garnish with fresh dill and a hefty squeeze of lemon juice – such a yummy combo with fish.

Are you a sardine fan?


  1. 1

    yum. I love sardines. I usually opt for the ones in mustard sauce. I may have to give this a try with the rye bread and greek yogurt/dijon smear.

  2. 3

    Interesting! I have never given sardines a chance because they have such a bad rep! This combo sounds really lovely though!

  3. 5

    Haha, yes! My bottom shelf is always filled with ALL the canned fish and sardines are the best!

  4. 7

    I LOVE sardines! Getting the ones packed in olive oil are life changing..the flavor is amazing. Trader joe’s has 2 kinds that I adore and Whole Foods has a brand is spicy pepper infused olive oil. Yum! I always put them on salads but never have tried a sandwich-thanks for the inspiration!

  5. 9

    So cool! I got all nostolgic reading this. I <3 Scandanvia. I am going to give this a try. :) And no extreme measurements required. ;)

  6. 11

    YUM! Give me all the cured fish. Smoked canned trout from TJ’s is my everything. I’ll definitely be making myself a Scandy Sandy (sorry, I had to) sometime very soon.

  7. 13

    Lol, love the Euro-ness going on here :) While I am not a huge fan of sardines myself, my Dad is a massive fan. I always bring him French or Portuguese sardines as a gift when I come back to the US. Not only are they shelf stable but they travel well too ;)

  8. 15

    This looks fantastic! World Market has carried wild caught sardines in lemon olive oil that Matt and I adored. I would love to make this for us soon!

  9. 16

    Anne, this is the first time I’ve seen sardines look appetizing. I actually want to try them! Thank you!

  10. 18

    Are you pregnant? The only time I ate sardines and I mean I ate them often was during both my pregnancies!

  11. 21

    I love sardines… and anchovies! But I usually only eat them fresh or out of a glass jar, which tends to be more expensive, but I don’t mess around with my fish.
