Grilled Smoked Salmon Crostini with Whipped Feta
A fast, grill-forward appetizer: thin, quick-smoked salmon slices perched on charred crostini with a silky whipped feta, tangy quick-pickled red onion, fresh dill and a bright squeeze of lemon. Ready in about 30 minutes, these crostini are perfect for fall entertaining or a party platter.
Jake Woods's note
"These crostini come together quickly and shine at cocktail parties or family gatherings — smoky-sweet salmon with bright pickled onion and creamy whipped feta is always a crowd-pleaser. Make them on a gas or charcoal grill (or indoor grill with a smoker box) for an easy impressive appetizer."
About This Recipe
Think of these crostini as an exercise in contrasts: crunchy, charred bread; lusciously smooth whipped feta with a lemony tang; silky, quickly smoked salmon; and a bright shock of pickled red onion and fresh dill. The technique—slicing the salmon thin, giving it a brief kiss of smoke, and building everything on a hot, charred crostini—lets each element read clearly on the tongue instead of muddling together. Because the feta is whipped until nearly mousse-like and the onions are only lightly pickled, the overall bite is immediate, balanced, and utterly snackable.
This version is designed for hosts who want big flavor without fuss. It comes together in about 30 minutes, scales easily for larger trays, and is forgiving if your timing isn’t exact: thin salmon cooks almost instantly, and the elements can be mostly prepped ahead. The quick-smoke step adds complexity without needing a full smoker or long brine, and the lemon finish brightens the inherent richness of the fish—exactly what you want from an appetizer that should disappear first off the platter.

- 3 tbsp Extra-virgin olive oil
- 1 tsp Kosher salt
- 8 oz Salmon fillet
- 6 oz Feta cheese

- 1/4 small Red onion
- 2 tbsp Red wine vinegar
- 2 tbsp Fresh dill
- 1/4 tsp Freshly ground black pepper
How to Make Grilled Smoked Salmon Crostini with Whipped Feta
Step 1: Quick-pickle the red onion
Active 4 min · Passive 10 min
Thinly slice the red onion and place in a small bowl. Add the red wine vinegar and 1/4 tsp of the kosher salt, stir to combine, and let sit at room temperature for 10 minutes so the onion softens and brightens; this is a quick pickle — no cooking required.For this step
- 1/4 smallRed onion
- 2 tbspRed wine vinegar

Step 2: Make the whipped feta
Active 4 min
In a food processor or with a hand blender, combine the feta cheese with 1 tbsp of the extra-virgin olive oil, the zest of the lemon and 1 tbsp of lemon juice, plus 1/8 tsp of the kosher salt. Blend until very smooth and spreadable, adding a teaspoon of water if needed to reach a creamy consistency. Transfer to a bowl and taste; adjust with a small pinch of salt if necessary.For this step
- 3 tbspExtra-virgin olive oil
- 6 ozFeta cheese

Step 3: Slice and oil the baguette
Active 4 min
Slice the small baguette on the diagonal into 12 slices (about 1/2-inch thick). Brush both sides of each slice with 2 tbsp of the extra-virgin olive oil and sprinkle the top sides with 1/4 tsp of the kosher salt so they’ll char and season as they grill.For this step
- 1 small (10–12 oz)Small baguette

Step 4: Char the crostini on the grill
Active 4 min
Preheat the grill to medium-high. Arrange the oiled baguette slices directly over the heat and grill 1–2 minutes per side, just until nicely charred and crisp — watch closely so they don’t burn. Remove and keep warm; these are your crostini base.
Step 5: Quick-smoke and grill the salmon
Active 11 min
Thinly slice the salmon fillet across the grain into 6–8 thin pieces. Season the slices with the remaining 3/8 tsp kosher salt and the freshly ground black pepper. Make a small foil packet with 1–2 tablespoons of soaked wood chips or use a smoker box; place the packet on the hot grill, then arrange the salmon over direct heat. Cover and allow the salmon to pick up smoke and cook for about 6–8 minutes (lid closed), then flip and grill 2–3 minutes more until just cooked through with a faint char — timing varies by thickness. Remove and let rest briefly.For this step
- 8 ozSalmon fillet
- 1/4 tspFreshly ground black pepper

Step 6: Assemble the crostini and garnish
Active 3 min
Spread about 1–1 1/2 tablespoons of the whipped feta on each crostini. Top each with a thin smoked salmon slice, a few strands of the quick-pickled red onion (drained), and a sprinkle of chopped fresh dill. Cut the remaining lemon into wedges and serve alongside so guests can add a bright squeeze of lemon juice to taste.For this step

Grilled Smoked Salmon Crostini with Whipped Feta Tips
Slice fish thinly
Cut the salmon across the grain into paper-thin slices so each piece picks up smoke and cooks quickly without drying out.
Soak wood chips properly
Soak chips for at least 20–30 minutes and wrap tightly in foil with vent holes to produce a short, controlled burst of smoke for flavor without overcooking.
Keep crostini crisp
Toast the baguette slices until well-charmed and cool them on a rack; store separately and assemble just before serving to avoid soggy bottoms.
Adjust feta consistency
If the whipped feta seems thick, add a teaspoon of cold water or extra lemon juice at a time until spreadable, then taste for salt.
Drain pickled onion well
Use tongs to lift the quick-pickled onions and give them a brief shake on paper towel so they add brightness but don’t make the crostini wet.
Grilled Smoked Salmon Crostini with Whipped Feta Variations and Substitutions
Use cold-smoked salmon
Substitute store-bought lox or gravlax—use slightly smaller amounts since it’s saltier, and skip the grilling step to keep its silky texture.
Dairy-free avocado spread
Replace whipped feta with smashed avocado blended with lemon zest and a pinch of salt for a creamy, dairy-free alternative that pairs beautifully with smoked salmon.
Gluten-free base
Swap the baguette for toasted gluten-free baguette slices or sturdy cucumber rounds for a lighter, gluten-free canape.
Herby whipped goat cheese
Use plain goat cheese in place of feta for a milder, tangier whipped spread; add a teaspoon of honey for a sweet-savory counterpoint.
How to Store and Make Grilled Smoked Salmon Crostini with Whipped Feta Ahead
Store components separately for best texture: keep whipped feta refrigerated in an airtight container for up to 4 days, and refrigerate any leftover smoked salmon for up to 24 hours. Crostini are best stored at room temperature in a sealed container and re-crisped in a hot oven (350°F/175°C) for 3–5 minutes before serving. Once assembled, eat within a few hours to avoid sogginess and preserve the crisp–cream–smoke contrast.
What to Serve With Grilled Smoked Salmon Crostini with Whipped Feta
Arrange the crostini on a long wooden board with little heaps of extra dill, drained pickled onion, and lemon wedges for guests to customize. Serve alongside a simple frisée or watercress salad dressed with lemon vinaigrette, and pair with a chilled Sauvignon Blanc, unoaked Chardonnay, or a bright, citrusy gin cocktail to match the dish’s herbal and acidic notes.
Grilled Smoked Salmon Crostini with Whipped Feta FAQs
Can I use pre-smoked salmon instead of grilling?
Yes—cold-smoked salmon (lox) works and speeds assembly; reduce or omit the added salt in the whipped feta since lox is often saltier than fresh grilled salmon.
How do I tell when the salmon is done?
Because the slices are thin, look for opaqueness and flakeability around the edges while maintaining a slightly translucent center; total cook time will be short—about 6–10 minutes depending on thickness and heat.
Can I make the whipped feta ahead of time?
Absolutely—whipped feta benefits from resting a few hours in the fridge for flavors to meld and will keep well for up to 4 days; stir briefly before using to restore spreadability.
My crostini got soggy—what went wrong?
Sogginess usually comes from assembling too early or adding wet toppings directly from their liquid; toast the bread well, drain pickled onions, and assemble just before serving to prevent it.
What wood chips are best for smoking the salmon?
Fruit woods like apple or cherry give a mild, sweet smoke that complements salmon without overpowering it; hardwoods like alder also work well for a classic, subtle smoke.
