Cook Mediterranean Tuna Hummus Crostini Like This

Follow these simple steps to create your Mediterranean Tuna Hummus Crostini:
Step 1: Preheat Your Oven
Begin by preheating your oven to 375°F (190°C). This is the perfect temperature for toasting the baguette slices to golden perfection.
Step 2: Slice the Baguette
Carefully slice the thin baguette into 1/2-inch thick slices. Aim for even slices to ensure uniform toasting.
Step 3: Brush with Olive Oil
Place the baguette slices on a baking sheet. Brush each slice lightly with olive oil, ensuring both sides are coated. This will help them crisp up beautifully in the oven.
Step 4: Toast the Baguette
Pop the baking sheet in the preheated oven and toast the baguette slices for about 10-12 minutes, or until they are golden brown and crispy. Keep an eye on them to prevent burning!
Step 5: Prepare the Tuna Mixture
While the baguette slices are toasting, open the cans of Genova Tonno Solid Light Tuna and drain the oil. In a mixing bowl, combine the tuna with chopped fresh basil, freshly squeezed lemon juice, salt, and black pepper. Mix gently to combine.
Step 6: Assemble the Crostini
Once the baguette slices are toasted and slightly cooled, spread a generous layer of hummus on each slice. Follow this with a spoonful of the tuna mixture, and then drizzle with pesto.
Step 7: Garnish and Serve
If desired, garnish each crostini with chiffonade fresh basil leaves for an extra pop of flavor and color. Serve immediately while the baguette is still warm and crispy.
Make It Year-Round

Mediterranean Tuna Hummus Crostini are not just a seasonal delight; they can be enjoyed year-round! Here’s how to keep this recipe fresh and exciting:
- Swap out the toppings: Experiment with different spreads like tzatziki or roasted red pepper dip.
- Seasonal herbs: Use fresh herbs that are in season, like dill or cilantro, to add unique flavor profiles.
- Add veggies: Top with sliced cherry tomatoes, olives, or arugula to enhance freshness.
- Cheese options: Sprinkle feta or goat cheese for a creamy contrast.
Slip-Ups to Skip
To ensure your Mediterranean Tuna Hummus Crostini turns out perfectly, keep these common pitfalls in mind:
- Over-toasting the baguette can lead to a hard texture. Keep an eye on them while baking.
- Using stale bread will affect the overall taste and texture. Opt for fresh baguette.
- Too much lemon juice can overpower the flavors. Start with a small amount and adjust to taste.
- Forgetting to drain the tuna properly can make the mixture too watery.
Meal Prep & Storage Notes
These crostini are best served fresh, but you can prepare some components in advance:
Store the toasted baguette slices in an airtight container at room temperature for up to 2 days. Keep the tuna mixture and hummus in the fridge, separately, for up to 3 days. Assemble the crostini just before serving to maintain the crunchy texture of the bread.
Frequently Asked Questions
Can I use canned tuna in water instead of olive oil?
Yes, you can! However, using tuna in olive oil adds a richer flavor and moisture to the crostini. If you choose to use tuna in water, consider adding a little extra olive oil to the mixture for taste.
Can I make my own hummus for this recipe?
Absolutely! Homemade hummus can elevate your crostini even more. Just blend cooked chickpeas, tahini, garlic, lemon juice, and olive oil until smooth for a delicious homemade version.
What could I serve alongside these crostini?
These crostini pair wonderfully with a simple green salad, roasted vegetables, or a platter of fresh fruit. You could also offer a selection of olives and cheeses for a Mediterranean-inspired spread.
Is there a vegetarian option for this recipe?
Certainly! Simply omit the tuna and add more veggies, such as marinated artichokes, roasted red peppers, or sun-dried tomatoes, to the hummus and pesto for a delicious vegetarian alternative.
