Hey! I hope you’re all having a great start to your week. I wanted to pop in before the Easter weekend to bring the sardine lovers here a fun and seasonal appetizer to pass around. Or! Just make a plate for yourself and treat it as a meal. That’s exactly what I did with these ;)

Spring produce!

When the topic of spring produce comes up, my mind immediately goes to sweet peas and crisp radishes. Even asparagus is a second thought in comparison to those two. There’s just something about peas and radishes—especially together—that screams freshness to me. Add some lemony anchovy butter and fresh dill to the equation, and you’ve got the perfect blend of complements for those tender omega-3 rich sardines.

In my time partnering with King Oscar, I’ve been challenged to think outside the box when it comes to working with sardines. I’ve incorporated them into Greek-inspired pitas and I’ve stuffed them into a melty, messy grilled cheese sandwiches. One thing that the folks at King Oscar and I have noticed, however, is that many sardine lovers are purists; they don’t feel the need to get fancy with their favorite little fish. And every once in a while, we like to recognize that with a recipe that’s on the simpler side.

King Oscar sardines don’t need fancying.

There’s a reason why these wild-caught brisling sardines in extra virgin olive oil are the brand’s most sought-after flavor. Even with mouthwatering variations like Mediterranean and Hot Jalapeño, the clean slate that is the brisling sardine in extra virgin olive oil wins. And that’s because quality food needs very little help. Like a good steak needs nothing more than a solid seasoning of salt and pepper, a good pack of sardines needs nothing more than some quality olive oil. (But trust me, the other flavors are totally worth digging into.) If you can’t find King Oscar’s sardines at your local supermarket, Amazon’s got your back

The refreshing flavors in this recipe let the sardine shine. I also decided to use King Oscar’s perfectly salty anchovies in my lemony anchovy butter. They are, hands down, the best tinned anchovies you’ll find at the supermarket.

I hope the rest of your week goes quickly, and I hope you have a wonderful weekend filled with delicious food!

I’ll be back next week with an incredible pizza recipe. You won’t want to miss it.

Lemon Anchovy Butter.

  • 1/2 cup softened butter (1 stick)
  • 1 2 oz can of King Oscar anchovy fillets, drained
  • 1 lemon, zested, then cut into wedges

Spring Canapés with Sardines.

  • 1 fresh French baguette, sliced diagonally into 1/2-inch thick slices (you should get about 16)
  • 2-4 red radishes, thinly sliced (preferably with a mandolin on the thinnest setting) Amount of radishes depends on their size and how thinly you can slice them, so eyeball it.
  • 1/4 cup peas Fresh peas are preferred. Sugar snap peas work wonderfully. If you can't get your hands on fresh, get frozen and thaw them prior to preparing your canapés.
  • 2 TBSP freshly chopped dill
  • Freshly squeezed lemon juice
  • 1 can of King Oscar brisling sardines in Extra Virgin Olive Oil; two layer or cross-pack. *See notes.


  • In a small bowl, thoroughly mix the butter, minced anchovy fillets, and lemon zest. Set aside.
  • Spread anchovy butter over one side of each baguette slice
  • Top each baguette slice with a few radish slices, peas, and a sardine fillet. Top with freshly chopped dill and drizzle with freshly squeezed lemon juice.


King Oscar's Brisling Sardines in Extra Virgin Olive Oil are available in a two layer pack with 12-22 fish and a cross-pack with 24-38 fish. Distribute the sardines over the crostini as you see fit depending on which tin you purchase.
Want to kick things up? King Oscar's Cracked Black Pepper brisling sardines would be a great substitute in this recipe.

    Oh man. You KNOW I’m a sucker for anything with gorgeous, seasonal produce. Then you hit me with that lemony anchovy butter. I could eat this as a meal and not an appetizer. Seriously. Amazing.

    I am completely crushing on the sound of that lemon anchovy butter! What a fantastic compound butter idea. The pairing with crispy radishes, peas, and dill is the epitome of a spring nosh. This would be a beautiful addition to a brunch spread. I already have a can of King Oscar Sardines in the pantry, so this will be on my table soon!

    You are so right, quality ingredients shouldn’t require over-seasoning or over-preparation. I love the simplicity of this appetizer, yet it looks so elegant. Easy to whip up at the last minute for hungry guests!

    These appetizers are so elegant and pretty! Nothing like spring peas and radishes to bring a pop of color. The sardines are a nice touch too. I feel like these would make great special occasion hors d’oeuvres.

    Dana, I love your approach to working with high-end canned fish. I think when a lot of us think of sardines, we don’t think of bright, produce-centric, springtime recipes like this. And lemon-anchovy butter?! WHAT? That’s incredible! I can imagine so many more things you could do with something like that! Awesome stuff!!

      For ages, the mention of sardines just reminded me of that scene from 80s movie with Tom Hanks called “The Burbs”. The creepy Klopek son greets him at the door with a plate of crackers and sardines and it’s anything but appetizing. Haha.

      The anchovy butter! I actually have some leftover in my fridge and I’m planning on trying something with it later today. Fingers crossed for another anchovy butter recipe in the near future.

    This is such an elegant canape!! I love love love sardines but not a lot of my friends do, but I don’t think they’ve had them like this before! I’m going to try this and hopefully change some of their minds. I just love all the spring flavors and colors on these!

      I’ve been known to sneak fish into recipes before ;)
      A bunch of my friends fell in love with another app I’ve made that uses cream cheese mixed with smoked kipper snacks. I told my friends halfway through and they were just like… “I had no idea I liked smoked fish this much.”

      So I say, sneak’em in :P

    These are adorable. Love how simple they are…but also elegant. I’m all about bite sized pick up food for a get together and these totally check that box. I like to serve something with a bit of protein….another box checked. Some veggies…check again. Beautiful. Check. Colorful and tasty too!!!

    Eating sugar snap peas is like eating candy. I love them and so does the rest of the family. I love how you made the crostini with fresh vegetables! What a great springtime appetizer. This is such a great idea I’m making this for the next gathering.

    These look and sound so delicious! They are the perfect spring appetizer for a party, and I would gladly gobble them up at home myself. Luckily, I just bought a can of sardines so I think I know how to put them to good use now!

    You had me at anchovy butter! And I can’t think of a better way to top these canapes than with fresh spring ingredients like radishes and snap peas. These would be lovely for a special brunch or even for Mother’s Day. Yum!

    Oh my gosh – I LOVE Sardines! People think I’m crazy but this recipe shows I’m not – I want to dig right in, yum! The lemon anchovy butter was magical too!

      In my mind, people either love sardines, or they’re wrong :) Haha. I truly do think it takes a quality sardine to convince people, though. I’ve had some that’ve been pretty meh. King Oscar’s are GOLD. Which is why I bug them to work with me every year, lol.

    Love sugar snap peas. I have them in the fridge all the time. Such a great healthy snack. Pairing them with sardines is a great idea. The sweet peas and salty fish would make an interesting and tasty appetizer. These look party perfect.
