Ingredients You’ll Need
You won’t believe how easy it is to create a showstopper with just a handful of thoughtfully chosen ingredients. Each element in these Assorted Tuna Crostini brings its own texture and punch of flavor, making every bite uniquely memorable.
- Extra-virgin olive oil: Go for the good stuff—its fruity richness adds gloss to each topping and toasts the bread beautifully.
- Garlic: A subtle rub of garlic perfumes the bread and toppings for irresistible aroma.
- French bread or ciabatta: Choose a loaf with a crisp crust and soft interior to yield the perfect crostini base.
- Ripe tomatoes: Juicy, vibrant tomatoes bring freshness to the bruschetta topping.
- Red onion: Adds a tangy crunch to balance sweet and savory components.
- Red wine vinegar: Lifts the tomato mixture with gentle acidity.
- Genova Yellowfin Tuna in Olive Oil: The hearty, silky texture and savory depth make this the heart of every topping.
- Salt and pepper: Never underestimate the magic of seasoning to elevate every flavor.
- Fresh basil: A classic partner with tomatoes, basil brings a fragrant green note to the bruschetta.
- Black and green olives: Their briny punch gives the tapenade its signature Mediterranean kick.
- Pimentos and capers: These add pops of color and sharp, salty accents for extra intrigue.
- Fresh parsley: A lively, herbal finish that brightens the olive topping.
- Avocado: Creamy and fresh, mashed with a splash of lemon for zing.
- Lemon juice: Keeps the avocado vibrant and adds welcome acidity.
- Yellow cherry tomatoes: Sweet little bursts that make the avocado variation sing.
- Scallions or chives: Sprinkle these on for a gentle, oniony freshness.
- Microgreens or sprouts: Add beautiful height and a hit of nutrition to your plating.
- Canned chickpeas: Popular for their nutty flavor and creamy-meets-chunky texture.
- Fresh rosemary: Earthy and piney, rosemary makes the chickpea topping truly special.
How to Make Assorted Tuna Crostini
Step 1: Toast the Bread
Preheat your oven to 425°F. In a small bowl, stir together the extra-virgin olive oil and crushed garlic. Give each bread slice a generous brush on both sides—this is where your golden, flavorful crunch starts! Arrange the slices on a baking sheet and toast for 5 to 8 minutes, flipping once halfway, until each piece is beautifully crisp and lightly golden.
Step 2: Prepare the Tomato-Basil Bruschetta Crostini
In a bowl, combine chopped tomatoes, minced red onion, a good glug of olive oil, a splash of red wine vinegar, and crushed garlic. Stir gently, then fold in a can of Genova Yellowfin Tuna. Season with salt and pepper. Top a quarter of your toasted bread slices with a lovely heap of the mixture, then shower with finely shredded basil for ultimate garden-fresh vibes.
Step 3: Make the Olive Tapenade Crostini
Grab another bowl and toss in the black and green olives, diced pimentos, parsley, and briny capers. Gently mix in the tuna until everything is shining and evenly distributed. Spoon this salty, savory tapenade over a second batch of toast.
Step 4: Assemble the Avocado Toast Crostini
Peel and pit the avocado, drop it into a medium bowl, and mash it up with lemon juice. Season to taste. Smear a generous layer onto yet another batch of bread slices, top with silky tuna, quartered yellow cherry tomatoes, a sprinkle of scallions or chives, and finish with microgreens or sprouts for pop and crunch.
Step 5: Build the Chickpea-Rosemary Crostini
Divide the chickpeas into two portions. Mash half the chickpeas with a drizzle of olive oil and a pinch of salt for creaminess. To the remaining chickpeas, toss in chopped red onion, fragrant rosemary, and fold in tuna, seasoning with fresh pepper. Spread the mashed chickpeas onto your remaining crostini, then layer on the chickpea-tuna mixture, pressing in gently. Just before serving, tuck in a tiny sprig of rosemary for a final herbal flourish.
How to Serve Assorted Tuna Crostini

Garnishes
Garnishing your Assorted Tuna Crostini is where your creative side gets to shine! Try adding a scatter of extra fresh herbs, a drizzle of your favorite olive oil, or something vibrant like lemon zest or colorful microgreens. Not only do they look stunning on a platter, but these little extras intensify the flavors and let your guests know this is more than your average appetizer.
Side Dishes
If you’re turning your Assorted Tuna Crostini into a spread, consider sides that keep things fresh and lively. A crisp green salad with citrus dressing, marinated artichokes, or an antipasti platter pair beautifully—and don’t forget a chilled glass of white wine or sparkling water with lemon to keep palates refreshed. The variety of flavors on your crostini makes mixing and matching with sides a total treat.
Creative Ways to Present
Presentation is half the fun, especially with something as colorful as Assorted Tuna Crostini! Arrange them in rows or alternating patterns on a big wooden board for a rustic, inviting look. If you’re serving in courses, place one of each variation on small plates for personal tasting flights. Or try stacking mini versions as “crostini towers”—guests will love how playful and interactive this dish can be!
Make Ahead and Storage
Storing Leftovers
If you find yourself with leftovers, separate the toppings from any uneaten crostini to preserve texture. Store both in airtight containers in the fridge; the toppings should keep for up to two days, though the freshness of herbs and avocado will fade quickest.
Freezing
While the tuna toppings (especially tapenade and chickpea) hold up reasonably well to freezing, avocado and tomato mixtures are best enjoyed fresh. Freeze just the bread if you must—once completely cool, wrap tightly and pop into a freezer bag for up to a month. Warm in the oven to restore crunch.
Reheating
Bring your crostini back to life by toasting the reserved bread in a hot oven for a couple of minutes until crispy. Always add your toppings after reheating, never before, to maintain those lively textures that make Assorted Tuna Crostini so irresistible.
FAQs
Can I use a different type of tuna instead of Genova Yellowfin?
Absolutely! While Genova Yellowfin brings wonderful, buttery flavor, you can substitute any high-quality tuna packed in olive oil. Just look for a variety with rich texture and gentle saltiness—skipjack or albacore works in a pinch.
How far in advance can I make Assorted Tuna Crostini?
You can prep the bread and most toppings up to six hours before serving; just wait to assemble and garnish until right before your guests arrive for the freshest results (especially with avocado).
Is there a gluten-free option for the bread base?
Absolutely! Pick your favorite gluten-free baguette or sliced bread—many toast up beautifully for crostini. Just keep an eye on texture, as some varieties cook faster than others.
What makes crostini different from bruschetta?
Though they’re often used interchangeably, crostini typically refer to smaller, crispier rounds of bread, while bruschetta is made with larger, rustic slices. Both are delicious, but crostini are perfect for a variety platter like this.
How do I keep the bread from getting soggy?
The real key is to toast the bread thoroughly and only add the toppings right before serving. If prepping in advance, store everything separately, then assemble your Assorted Tuna Crostini at the last minute for the ideal crunch.
Final Thoughts
There’s just something magical about inviting friends over and watching them light up over a tray of Assorted Tuna Crostini. The colors, the variety, the ooohs and ahhhs with that first bite—it’s always a hit! Try the recipe and let it be the star (or the crowd-pleaser snack) at your next gathering. You’ll wonder how your parties ever did without it.
