How to Make Smoked Salmon Crostini Egg Mousse Recipe
Step 1: Prepare the Velvety Egg Mousse
Start by combining the hard-boiled eggs, softened cream cheese, shredded sharp cheddar, granulated garlic, Dijon mustard, fresh lemon juice, ground turmeric, sea salt, and black pepper in a food processor. Blend everything until the mixture becomes mostly smooth. Don’t forget to pause occasionally and scrape down the bowl’s sides to ensure an even blend. This step is where the magic begins, as these ingredients meld into a rich and creamy base that defines the mousse’s character.
Step 2: Achieve the Perfect Silky Consistency
Once mostly smooth, add 5 to 10 millilitres of warm water to the processor and continue blending until the mousse reaches a silky, glossy texture that’s perfect for piping. This warm water addition is a small but critical trick to get your mousse spreadable yet stable enough to hold those beautiful swirls later.
Step 3: Chill for Set Texture
Transfer the mousse into a piping bag and refrigerate it for 15 to 20 minutes. This chilling period firms up the mousse just enough so it can hold its shape when piped onto the crostini, making your presentation polished and impressive.
Step 4: Toast the Crostini to Golden Perfection
Preheat your oven to 205°C. Lightly brush the diagonal baguette slices with olive oil to encourage golden crispness, then arrange them on a baking sheet. Toast for 7 to 10 minutes until they turn beautifully golden and crunchy. The crisp crostini provide the perfect sturdy base and lovely contrast to the smooth mousse.
Step 5: Infuse Garlic Flavor into the Warm Crostini
As soon as the crostini come from the oven and are still warm, rub them gently with the cut side of a fresh garlic clove. This simple step infuses a subtle but irresistible garlic aroma, lifting the entire dish.
Step 6: Assemble Your Smoked Salmon Crostini Egg Mousse
Start by spreading a thin layer of egg mousse on each crostini to anchor the topping. Then pipe a decorative swirl of the mousse on top for a visually captivating and gourmet touch. Roll thin slices of smoked salmon into loose rosettes and nestle them atop each swirl. Finish each crostini with a fresh dill sprig and a pinch of black sesame seeds for a burst of color, flavor, and texture.
How to Serve Smoked Salmon Crostini Egg Mousse Recipe
Garnishes
Fresh dill sprigs and black sesame seeds are your go-to garnishes that add not only aesthetic appeal but also layers of fresh and nutty flavors. You might also consider edible flowers or finely chopped chives to introduce light herbal and floral notes that complement the smoky and creamy elements beautifully.
Side Dishes
This Smoked Salmon Crostini Egg Mousse Recipe pairs wonderfully with a crisp green salad dressed in a lemon vinaigrette to balance richness or perhaps a chilled cucumber soup for a refreshing contrast. Light, citrusy sides amplify the fresh elegance of this appetizer without overwhelming it.
Creative Ways to Present
Try arranging the crostini on a rustic wooden board with lemon wedges for an inviting and vibrant display. For parties, serve the mousse in shot glasses alongside mini crostini for a hands-on experience. You can also experiment by layering the mousse and smoked salmon in small glass jars, adding a modern, layered twist that’s both portable and visually appealing.
Make Ahead and Storage
Storing Leftovers
Store any leftover mousse in an airtight container in the refrigerator for up to 2 days to maintain its freshness and texture. Keep toasted crostini separate in a sealed container at room temperature to preserve crispiness. Assembling crostini ahead of time is not recommended as the bread can become soggy.
Freezing
The mousse itself can be frozen for up to one month in a tightly sealed container. Thaw it in the fridge overnight before using. However, avoid freezing the crostini as their texture will deteriorate and become too soft upon thawing.
Reheating
Reheat crostini gently in a preheated oven at 180°C for 3 to 5 minutes to regain some crispness, but avoid overheating to prevent dryness. The mousse should be served cold or at room temperature, so do not reheat it—just give it a gentle stir after waking up from the fridge or freezer.
FAQs
Can I use regular mustard instead of Dijon mustard?
While Dijon mustard offers a smoother and slightly tangier profile that suits this recipe perfectly, you can substitute with regular mustard if needed. Just keep in mind the flavor might be a bit sharper or more pungent, so start with less and adjust to taste.
What type of smoked salmon works best?
Look for thinly sliced, high-quality cold-smoked salmon with a delicate texture and clean flavor. Avoid heavily cured or overly salty varieties to maintain balance with the creamy egg mousse.
Can I make the egg mousse vegan or dairy-free?
This particular version relies on eggs and dairy for its creamy, rich texture, so veganizing it would require a completely different approach. However, to make a similar mousse, you might explore mashed silken tofu or avocado bases with plant-based cream cheese alternatives alongside suitable flavorings.
Is this recipe suitable for gluten-free diets?
The mousse itself is naturally gluten-free, but standard baguette crostini contain gluten. You can replace them with gluten-free bread slices or crackers to accommodate dietary restrictions without sacrificing the delightful combination of crispy base and smooth topping.
How far in advance can I prepare this dish for a party?
You can prepare the mousse up to a day ahead and keep it chilled in the refrigerator. Toast and garlic-rub crostini can also be made a few hours ahead and stored properly. Assemble immediately before serving to ensure the crostini remain crisp and the presentation stays fresh.

Ingredients
Egg Mousse
- 3 hard-boiled eggs

- 60 grams sharp cheddar cheese, shredded
- 0.25 teaspoon granulated garlic
- 1 teaspoon Dijon mustard
- 1 teaspoon freshly squeezed lemon juice
- 0.33 teaspoon ground turmeric
- Fine sea salt, to taste
- Freshly ground black pepper, to taste
- 5–10 millilitres warm water
Crostini
- 1 baguette, sliced diagonally
- 30–45 millilitres olive oil
- 1 fresh garlic clove, halved
Toppings
- 85 grams smoked salmon, thinly sliced
- Fresh dill sprigs
- Black sesame seeds
Instructions
- Prepare the egg mousse: Place the hard-boiled eggs, softened cream cheese, shredded sharp cheddar, granulated garlic, Dijon mustard, lemon juice, ground turmeric, sea salt, and freshly ground black pepper into a food processor. Blend until mostly smooth, stopping occasionally to scrape down the sides to ensure even mixing.
- Adjust mousse consistency: Add 5 to 10 millilitres of warm water to the mixture and continue blending until the mousse is silky, glossy, and has a pipeable consistency suitable for decorating.
- Chill the mousse: Transfer the mousse into a piping bag and refrigerate for 15 to 20 minutes. This helps the mousse to set and become firmer for spreading and piping.
- Toast the baguette slices: Preheat your oven to 205°C (400°F). Lightly brush the diagonal slices of baguette with olive oil, arrange them evenly on a baking sheet, and toast in the oven for 7 to 10 minutes until they turn golden brown and crisp.
- Garlic rub: Remove the toasted crostini from the oven and immediately rub each slice with the cut side of the halved garlic clove. This infuses a subtle garlic flavor into the warm bread.
- Assemble the crostini base: Spread a thin layer of the chilled egg mousse onto each garlic-rubbed crostini. This base layer helps anchor the decorative piping on top.
- Pipe mousse decoration: Using the piping bag, create a decorative swirl of the egg mousse atop the base layer on each crostini for an appealing presentation.
- Add smoked salmon and garnish: Roll thin slices of smoked salmon into loose rosettes and place one on each mousse-topped crostini. Garnish with fresh dill sprigs and sprinkle a pinch of black sesame seeds for added flavor and visual appeal.
Notes
- Ensure eggs are cooled completely before processing for best texture.
- The tartness of the lemon juice balances the richness of the cheese and eggs.
- Adjust warm water quantity gradually to control mousse consistency.
- Use fresh garlic for the crostini rub to avoid overpowering flavor.
- Serve immediately after assembly to maintain crispness of the crostini.
- Leftover mousse can be stored in an airtight container in the fridge for up to 2 days.
