Ingredients You’ll Need

This recipe uses fresh, pantry-friendly ingredients that come together to create that signature flavor combo. Whether you’re heading to the store or raiding your fridge, here’s what to look for.

• Pesto: Choose your favorite basil pesto or make your own for extra freshness.
• Mayonnaise: I use regular mayo here but feel free to swap with a lighter version if you prefer.
• Chili Crunch: This is your secret weapon for heat and texture—if you can’t find it, a chili garlic sauce is a decent substitute.
• Honey: Just a touch to balance the spice in the aioli.
• Lemon Juice: Freshly squeezed is best to brighten up both the aioli and tuna mix.
• Fine Salt & Pepper: Season to taste—it really makes the flavors pop.
• Canned Tuna: Make sure to drain it well; I prefer chunk light for texture.
• Dijon Mustard: Gives a subtle tang and depth to the tuna mixture.
• Lemon Zest: Adds that fresh citrus aroma I can’t get enough of.
• Garlic Cloves: Fresh garlic adds a punch—don’t skip it!
• Capers: They bring a salty, briny contrast that’s essential here.
• Anchovy Paste or Filets: Believe it or not, this umami boost transforms the sandwich into something next level.
• Dill (Fresh or Dried): A lovely herbaceous note that rounds out the tuna mixture.
• Red Onion: For a bit of crunch and sharpness.
• Whole Wheat Flatbread, Sourdough, or Focaccia: Any sturdy, thin bread works great; toasting it adds the perfect crunch.
• Tomato Slices: Fresh and juicy, they keep the sandwich bright and light.
• Ripe Avocado: Creamy and buttery—this is the “cado” in the tunacado!
• Pickled Banana Peppers: Optional, but I love the tangy heat they add.

Variations

I love how versatile this Tunacado Sandwich with Spicy Pesto Aioli Recipe is. You can easily swap ingredients or add new ones to make it your own. Here are a few ways I’ve experimented:

• Make it vegan: I once swapped the tuna for chickpeas mashed with a bit of smoked paprika, and it was surprisingly satisfying with the aioli.
• Spice level: If you’re sensitive to heat, just dial down the chili crunch or leave out the banana peppers; for more fire, add a pinch of cayenne to the tuna mix.
• Cheese add-in: My family sometimes requests a slice of fresh mozzarella to melt on top—so good!
• Seasonal greens: Swap in arugula or fresh spinach for extra freshness and crunch.

How to Make Tunacado Sandwich with Spicy Pesto Aioli Recipe

Step 1: Whip Up the Spicy Pesto Aioli

Start by combining pesto, mayonnaise, chili crunch, honey, and lemon juice in a small bowl. I find stirring it all by hand with a spoon works best for keeping that beautifully textured aioli. Taste it and season with salt and pepper as you like. Set this aside—it’s the zingy spread that ties the sandwich together! Pro tip: If you want it spicier, just add a little more chili crunch gradually.

Step 2: Create the Creamy Tuna Mixture

Next, grab a food processor. Toss in the tuna, mayonnaise, dijon mustard, lemon zest and juice, garlic cloves, capers, anchovy paste, and dill. Pulse on high, stopping occasionally to scrape down the sides. You’re aiming for a smooth but still slightly whipped texture. After that, stir in the diced red onion, salt, and pepper manually—this preserves a little crunch and sharpness. If you don’t have a food processor, finely mash everything well with a fork—it just might take a bit more elbow grease!

Step 3: Toast the Bread to Crispy Perfection

I’m pretty picky about bread texture here—thin, crispy bread is a must for contrast. Heat a tablespoon of oil in a skillet over medium-high heat. Place two slices of bread cut side down, and to get them extra crisp, I place a small weighted pan on top. Cook for 2–3 minutes until golden and lightly browned. Repeat with the remaining slices. This step adds that unbeatable crunch, so don’t skip it—even if you’re using sourdough or focaccia.

Step 4: Assemble Your Tunacado Sandwich Masterpiece

Spread a good layer of the spicy pesto aioli on the toasted sides of all the bread slices—that’s going to give you brightness and heat in every bite. Then spoon the tuna mixture evenly over two of the slices. Top each with tomato slices and as much sliced avocado as you can handle. Add pickled banana peppers for a punchy brininess if you like. Close your sandwich halves, slice them for easier handling, and get ready to indulge.

How to Serve Tunacado Sandwich with Spicy Pesto Aioli Recipe

Garnishes

I usually stick with simple garnishes like fresh basil leaves or a sprinkle of chopped fresh dill to echo the flavors inside. Sometimes I like to add a few extra pickled banana peppers on the side for guests who want an extra kick. These touches add freshness and a pop of color that make each bite feel fresh and vibrant.

Side Dishes

A crunchy side salad with lemon vinaigrette pairs perfectly—I love arugula or mixed greens with shaved fennel. Alternatively, sweet potato fries or a light soup, like gazpacho, complement the richness of the sandwich without overpowering it.

Creative Ways to Present

For casual gatherings, I’ve served this sandwich as finger food by cutting it into small, manageable triangles arranged on a platter with toothpicks. It ends up looking beautiful and inviting. For a cozy lunch, plate it alongside colorful seasonal fruit for a vibrant plate that feels special.

Make Ahead and Storage

Storing Leftovers

If you happen to have leftovers (though I rarely do!), store the tuna mixture separately in an airtight container in the fridge for up to 2 days. Keep any avocado slices and the bread separate to avoid sogginess.

Freezing

I’ve tried freezing the tuna mixture without the fresh avocado or bread, and it freezes well for up to a month. Just thaw in the fridge overnight and stir before using—it won’t be quite as fresh but perfect for a quick meal.

Reheating

Since the bread is toasted fresh, I recommend reheating any leftovers by warming the tuna mixture separately and then assembling the sandwich right before eating. If you want to toast the bread again, a dry skillet works wonders to crisp it back up without drying it out.
