It's officially party season! And you know what that means … APPETIZERS! Appies, tapas, picky bits, party bites. Whatever you call them, they make eating fun.

This seared tuna recipe is a take on a recipe made by Chef Dino Renaerts. He made his with flame torched mackerel, which was SO GOOD!

I've chosen to use easier to find Pacific Albacore tuna and sear it in a hot pan. Chef Renaerts served his on baguette slices while I opted for a paleo and gluten-free friendly sliced cucumber. I kept his tapenade exactly the same, because why mess with perfection.

I know that seared tuna sounds like a fancy recipe that is hard to make, but trust me, it's super easy. The best part is that it can be made 100% in advance so there is no fiddling around last minute trying to put together your appy while your friends are knocking at your door.

Make ahead appetizers are the best for parties! Especially ones that look as pretty and are as tasty as this seared tuna.

The star of this recipe is the Spanish manzanilla olive tapenade. Manzanilla Olives from Spain are buttery, smooth flavored, and are not overly salty. They're absolutely perfect in the tapenade as they don't overpower the seared tuna.

Interviewing Chef Dino Renaerts, I found out we had something in common; our love for Olives from Spain. I have a hard time picking a favorite variety as they're all so good. His favs are the Spanish manzanillas used in this recipe.

He describes manzanilla olives from Spain as ‘having a really great umami factor.”

The best takeaway from the night was learning how Renaerts, who told me he was ‘born on olives', likes to serve them when he's at home with his friends and family. He said he likes to toss them in fennel seeds and chili flakes then reheat them in olive oil to bring out their fragrance.

It reminded me of the Easy Marinated Olives from Spain recipe I shared with you earlier this year.

How to make seared tuna bites with manzanilla olives from Spain tapenade

  1. Start with buying sushi-grade Pacific Albacore tuna. And please make sure that it is caught with a pole and line! (ie: avoid buying any tuna that was caught with longlines.)
  2. Next, season both sides with a little salt and lots of pepper.
  3. Then sear the tuna steak for about 1 1/2 minutes on each side in a super hot pan. This is the only tricky-ish step as we all tend to want to overcook meat. Just remember, this is sushi-grade tuna that can be eaten completely raw.
  4. Now all you have to do is slice the tuna, pop the slices on cucumber rounds, and top with a little of the tapenade. To make them extra pretty you can finish them with a tiny basil leaf.

That's it!

And if you don't have any parties in the near future, you can turn these seared tuna bites into lunch. Slice the tuna, fan it out over an arugula salad, and top with the Spanish manzanilla olive tapenade. So easy and so delicious!
