Summary

A modern appetizer that’s as elegant as it is effortless.

This is my favorite way to eat smoked trout. These Lemon Crème Smoked Trout Crostinis layer smoky, flaky trout over a blend of yogurt, crème fraîche, and lemon giving it a light creamy body and freshness. Unlike most smoked fish dips you may come across, that is overly heavy with cream cheese, this is light and refreshing. Topped with chives and microgreens, each bite is vibrant, rich, and balanced — a restaurant-level dish you can make in minutes.

Smoky meets sunny. Flaky smoked trout sits atop a lemony yogurt–crème fraîche spread that is light, fresh, and miles from heavy cream-cheese dips. Finished with chives and microgreens, each crostini is crisp, vibrant, and restaurant-fancy in minutes.

Ingredients

  • 272 g 2 cups smoked trout, skins removed (about 6–8 small fillets)

  • 114 g 1/2 cup plain whole-milk Greek yogurt

  • 110 g 1/2 cup crème fraîche

  • 24 g 2 tbsp mayonnaise

  • 36 g 3 tbsp extra-virgin olive oil, divided

  • 0.5 g 1 tsp lemon zest (about 1 lemon)

  • 18 g 3.5 tsp fresh lemon juice, divided (about 1/2 lemon)

  • 1 g 1/2 tsp black pepper, divided

  • 3 g 1/2 tsp kosher salt, divided

  • 220 g 1 medium baguette (about 12 slices, 3/4 inch thick)

  • 9 g 3 tbsp chives, finely chopped

  • 24 g 1 cup microgreens (radish or broccoli)

Equipment

Directions

  • Before We Start

    Resting Time: For best results, make the trout and cream mixture, then put in the fridge for an hour or two. This will firm up the mixture and allow the smoke some time to integrate with the rest of the dip, giving you a better texture and well rounded smoky flavor.
    Timing the bread: It is best to toast the bread just before serving. It starts getting overly hard if you let is sit for several hours. Also, top with the trout mixture, just before serving. You don’t want to set it on top of the bread and leave it for a long time.
    Micro greens: You can use pretty much and small micro greens you can find. I would avoid pea shoots though.
    Chives vs green onion: I think chives are a the best option here, you can use green onion if that is all you can find, but it is worth the extra effort to find fresh chives. They are not as pungent as green onion, so the results are more subtle.
  • Make the Lemon Crème Base

    For the Crème Base
    114 g | 1/2 cup plain Greek yogurt, whole milk
    110 g | 1/2 cup crème fraîche
    24 g | 2 tbsp mayonnaise
    36 g | 3 tbsp extra-virgin olive oil, divided
    0.5 g | 1 tsp Lemon zest, about 1 lemon
    10 g | 2 tsp fresh lemon juice, about 1/3 a small lemon
    0.5 g | ¼ tsp black pepper
    1 g | ¼ tsp kosher salt (adjust to taste)
     
    Zest and half one lemon. In a medium bowl, whisk together yogurt, crème fraîche, mayonnaise, olive oil, salt, pepper, and lemon zest and juice until smooth.
  • Shred the Trout

    Smoked trout can sometimes flake easily or be harder to separate.
     
    What I have found as the easiest method for getting a good texture for the trout is to remove the trout from the skin and place in a medium sized bowl. Then break the trout up with your hands or two forks until about 1/2 – 1in in size.
     
    Then use a medium sized whisk and stir up the fish until the meat starts to break apart into a more flaky texture.
     
    Once the majority of the fish is the right size and texture, user your hands to break up and remaining pieces that are too large. There shouldn’t be any super large bits of trout, it is meant to be something that can incorporate into the crème base well.
  • Fold in the Smoked Trout

    Gently fold the smoked trout into the lemon crème base with a spatula until evenly combined. Avoid working the trout too much, we want to preserve the texture.
     
    Smoked trout can come in varying levels of saltiness, so taste and adjust the salt levels and acid (add extra lemon juice if needed).
  • Refrigerate (Optional)

    We find more of the smokiness comes through more if you let this sit for an hour or two before serving. If not serving right away, cover and place the mixture in the fridge until you are ready to serve.
     
    Note: You can let is sit overnight as well, although, it would be best to omit adding the lemon juice until you are ready to serve, since the brightness of lemon juice will start to dull otherwise.
  • Prep your topping

    Lemon Wedges: Cut the remaining portion of the lemon into wedges
    Chives: Wash and bunch the chives together, use a damp paper towel to roll the chives into a cigar. Finely chop the chives. Sliding more out as you get closer to the towel. This ensures the chives don’t smash as you cut them.
  • Toast or Grill the Crostinis

    For the Crostinis
    220 g | 1 medium baguette (about 12 slices, ¾ inch thick)
    12 g | 1.5 tbsp extra-virgin olive oil
    1 g | ¼ tsp kosher salt
     
    Cut a baguette into 3/4 in slices. You will need at least 12 slices, I like having a few extras just in case some get overly burned on the grill.
     
    Brush both sides with olive oil and a very light sprinkle of salt.
     
    If grilling: Preheat the grill on high to get your grates very hot. Lower the flame to medium and add the bread in a diagonal. Toast for 1–2 minutes per side until lightly charred. For us 75-90 seconds was perfect.
     
    If using the oven: Bake at 400°F (200°C) for 6–8 minutes, until golden brown.
  • Assemble the Crostinis

    For Topping
    9 g | 3 tbsp chives, finely chopped
    24 g | 1 cup micro greens, radish or broccoli
    0.5 g | ¼ tsp black pepper, freshly cracked
    6 g | 1/2 tbsp extra-virgin olive oil
    8 g | 1.5 tsp lemon juice, freshly squeezed (about 1/8 a lemon)
     
    Spoon the trout mixture onto each slice. Top with finely chopped chives, radish microgreens, drizzle a small amount of extra virgin olive oil, and a few cracks of black pepper.
     
    If it needs additional salt, top with lightly crushed Maldon flakey salt or a light pinch of kosher salt.
  • Finish & Serve

    Using the lemon wedges give them a light squeeze over the crostini’s at the table. Serve immediately while the bread is crisp and the topping cool. Enjoy.

Additional Details About This Recipe

Can I make the trout mixture ahead of time?

Yes. It actually improves after a few hours in the fridge. Just give it a quick stir before serving.

Can I substitute the yogurt or crème fraîche?

If needed, use sour cream in place of crème fraîche, but avoid skipping the yogurt, it gives that balanced tang and lightness.

What’s the best bread to use?

A slender baguette or demi-baguette works best. You can also use toasted sourdough or crostini crackers, but just cut into reasonable sizes and don’t over toast since sourdough usually has a very hard thick crust.

How long can leftovers last?

The trout mixture will keep for up to 2 days refrigerated in an airtight container. Toast bread fresh each time for the best texture.
