Step‑by‑Step Instructions for Smoked Salmon Crostini
Step 1: Make the Mousse
Begin by combining hard-boiled eggs, cream cheese, sharp cheddar cheese, Dijon mustard, lemon juice, turmeric, granulated garlic, salt, and black pepper in a blender or food processor. Blend on high until the mixture is completely smooth and creamy, which should take about 2–3 minutes. Gradually add 1–2 teaspoons of warm water to reach a silky consistency, then transfer the mousse to a piping bag and refrigerate for at least 15 minutes to chill.
Step 2: Prepare the Crostini
Preheat your oven to 400°F (205°C) as you slice the baguette diagonally into ½-inch thick pieces. Arrange the slices on a baking sheet and brush the tops lightly with olive oil. Place the baking sheet in the oven and toast for about 5–7 minutes or until golden and crisp. Keep a close eye on them to prevent burning; the crostini should have a lovely golden color when ready.
Step 3: Infuse with Garlic
Once the crostini are toasted, remove them from the oven and allow them to cool slightly. Take a fresh garlic clove and cut it in half. While the bread is still warm, gently rub the cut side of the garlic on each piece, providing a subtle garlic flavor that enhances the overall taste of the Smoked Salmon Crostini without overpowering it.
Step 4: Assemble the Crostini
Now it’s time to assemble these delightful crostini! Grab your piping bag filled with the chilled egg-cheddar mousse and pipe a thin layer onto each toasted crostini base. This adds a creamy layer, and remember, a decorative swirl on top can elevate your presentation. Make sure the mousse covers the bread fully for flavor in every bite.
Step 5: Add the Smoked Salmon
Next, take thin slices of smoked salmon and gently roll them into rose shapes. Carefully place one salmon rose on top of the piped mousse of each crostini, allowing the beauty of the salmon to shine through. The delicate pink of the salmon contrasts beautifully with the creamy mousse, completing the stunning visual appeal of your Smoked Salmon Crostini.
Step 6: Garnish and Serve
Finally, finish off your masterpiece by garnishing each crostini with a sprinkle of fresh dill and black sesame seeds for added crunch and flair. This will not only enhance the flavor but also make your appetizer pop with color. Serve immediately to maintain the crispy texture of the crostini and enjoy the impressed reactions from your guests!

Storage Tips for Smoked Salmon Crostini
Mousse Storage: Keep the egg-cheddar mousse in an airtight container or piping bag in the fridge for up to 24 hours before serving. This makes it easy to prepare ahead of time.
Crostini Storage: Toasted crostini can be made several hours in advance; store them uncovered to maintain their crispiness until ready to use.
Salmon Preparation: You can prepare the smoked salmon roses in advance, placing them in an airtight container in the fridge until you’re ready to assemble.
Reheating: If you have leftover assembled crostini, consume them within a few hours for optimal texture. If needed, refrigerate for up to 1 day, but be aware that the crostini may lose their crispness.

Expert Tips for Smoked Salmon Crostini
• Perfect Eggs: Ensure your hard-boiled eggs are fully cooked to achieve a smooth mousse texture—undercooked eggs can result in an undesirable consistency.

• Piping Techniques: For an appealing presentation, pipe the mousse onto the crostini instead of spreading it; this creates an elegant look that impresses at any gathering.
• Garlic Infusion: Rubbing the toasted crostini with fresh garlic only adds a gentle hint of flavor; don’t skip this step, as it enriches the overall taste without overpowering the dish.

Smoked Salmon Crostini Recipe FAQs
How do I choose ripe ingredients for my Smoked Salmon Crostini?
Absolutely! When selecting smoked salmon, look for vibrant color and a fresh smell; any dull or off odor indicates it’s past its prime. For the baguette, ensure it’s crusty and firm, not stale or overly soft. Fresh dill should be bright green and fragrant, avoiding any wilting or yellowing.
What’s the best way to store the smoked salmon mousse?
Very simple! Store any leftover egg-cheddar mousse in an airtight container or piping bag in the refrigerator. It stays fresh for up to 24 hours. Just be sure to keep it well-sealed to maintain its silky texture and avoid drying out.
Can I freeze the smoked salmon crostini?
While it’s not ideal for the entire assembled dish, you can freeze the mousse! Place it in an airtight container, and it will keep well for up to 3 months. When ready to use, thaw it in the refrigerator overnight, then re-whip if needed for that perfect creamy texture. For the crostini, it’s best to toast them fresh to keep that delightful crunch.
What if my mousse is too thick or too thin?
No worries! If your mousse is too thick, blend in a little extra warm water one teaspoon at a time until you achieve the desired consistency. On the other hand, if it’s too thin, add a bit more cream cheese or hard-boiled egg to thicken it up. Remember, achieving the right texture is all about gradual adjustments!
Are there any dietary considerations I should be mindful of?
Great question! This Smoked Salmon Crostini contains common allergens such as dairy (cream cheese and cheddar) and eggs. If serving to guests, it’s wise to check for any allergies. Additionally, consider using gluten-free baguette options for a celiac-friendly version. Enjoy this elegant appetizer without worry!
How can I keep my crostini crispy after preparing?
The more the merrier! To maintain the crispness of your crostini, assemble them just before serving. You can prepare the toasted bread a few hours in advance and keep it uncovered at room temperature to prevent moisture buildup. Just remember, once you add the mousse and salmon, the crostini will start to soften, so timing is key!
