Ingredients You’ll Need

The ingredients for this Tunacado Sandwich with Spicy Pesto Aioli Recipe bring together bright, fresh flavors and creamy textures that complement each other perfectly. Don’t worry if you haven’t used anchovy paste or chili crunch before—they add depth without overwhelming, and I’ll share my tips for using them just right.

• Pesto: Store-bought or homemade will work; it’s the flavor base of the aioli, adding that herby punch you’ll love.
• Mayonnaise: You’ll use it both in the aioli and the tuna mix—it provides that creamy texture that holds everything together.
• Chili Crunch: This is a crunchy chili oil seasoning that adds texture and heat; if you don’t have it, a drizzle of your favorite hot sauce can work!
• Honey: Just a touch to balance the heat and acidity in the aioli.
• Lemon Juice & Zest: They brighten the whole sandwich, giving it a fresh lift that you don’t want to miss.
• Canned Tuna: Use good-quality, drained tuna packed in water or oil based on your preference.
• Dijon Mustard: Adds tang and complexity to the tuna mix.
• Garlic: Fresh garlic cloves add a subtle bite—don’t skip them!
• Capers: Their salty brine balances the rich avocado and tuna beautifully.
• Anchovy Paste or Filets: The secret umami bomb that deepens flavor without tasting fishy.
• Dill: Fresh or dried dill complements the other herbs wonderfully.
• Red Onion: Adds a crisp, sharp contrast to the creamy filling.
• Bread: I recommend whole wheat flatbread, sourdough, or focaccia—something sturdy and easy to crisp up.
• Tomato: Fresh, ripe slices make every bite juicy and refreshing.
• Avocado: Creamy and buttery, the star that gives the sandwich its ‘tunacado’ charm.
• Pickled Banana Peppers (optional): Add a tangy, spicy kick if you like a little extra zip.

Variations

I love how flexible this Tunacado Sandwich with Spicy Pesto Aioli Recipe is. Sometimes I like to switch things up depending on what’s in my fridge or what kind of mood I’m in. Feel free to make it your own because that’s part of the fun!

• Make it Vegetarian: Skip the tuna and add smashed chickpeas or mashed white beans instead for a similar texture and protein boost.
• Spice it Up More: I sometimes add extra chili crunch or a few dashes of cayenne if I want a bigger kick.
• Change the Bread: I’ve tried it with gluten-free flatbread and even on thick toasted rye for a heartier meal.
• Fresh Herbs: Swapping dill for fresh basil or parsley gives a fresh twist worth exploring.

How to Make Tunacado Sandwich with Spicy Pesto Aioli Recipe

Step 1: Whip Up the Spicy Pesto Aioli

Start by combining the pesto, mayonnaise, chili crunch, honey, and lemon juice in a small bowl. Give it a good stir until everything is fully combined and creamy. Season it with salt and pepper to your liking. This sauce is like the magic glue that makes the sandwich sing, so taste as you go! Set it aside while you prepare the tuna filling—it lets the flavors meld together beautifully.

Step 2: Make the Creamy Tuna Filling

Place your drained tuna, mayonnaise, Dijon mustard, lemon zest, lemon juice, garlic cloves, capers, anchovy paste (or filets), and dill into a food processor. Pulse it until the mixture becomes smooth, almost like a whipped salad filling. Don’t rush this step because the right texture is key—you want it creamy but with a little body. If you don’t have a food processor, finely mashing and mixing with a fork or potato masher works too! Then fold in the diced red onion along with salt and pepper, adjusting seasoning as needed.

Step 3: Toast the Bread to Crispy Perfection

Heat one tablespoon of oil in a skillet over medium-high heat. Toast two pieces of bread at a time cut side down for 2 to 3 minutes until golden and crispy. I like to weigh them down with a small skillet or lid so they get extra crusty. Then toast the other two slices. This step transforms your sandwich from ordinary to extraordinary with a satisfying crunch.

Step 4: Assemble Your Tunacado Sandwich

Spread a generous layer of the spicy pesto aioli on the toasted side of each bread slice. Divide the tuna mixture evenly on two pieces, then layer with tomato slices and avocado. If you love a bit of tang and heat, add some pickled banana peppers on top. Close your sandwich, slice it in half, and get ready to enjoy a bite that’s creamy, spicy, and utterly satisfying.

How to Serve Tunacado Sandwich with Spicy Pesto Aioli Recipe

Garnishes

I love topping my tunacado sandwich with extra baby arugula or a sprinkle of freshly cracked black pepper. Sometimes I add an extra squirt of lemon juice right before serving—it brightens things up perfectly. Pickled jalapeños or banana peppers add a zesty punch that my family always asks for.

Side Dishes

This sandwich pairs wonderfully with a crisp green salad or a handful of kettle-cooked chips. On lazy weekends, I like serving it with crispy sweet potato fries—they add just the right balance of sweet and savory. A simple pickle on the side also complements the flavors nicely.

Creative Ways to Present

For a fun gathering, I’ve assembled these as open-faced sandwiches on toasted crostini rounds for impressive finger food. Another time, I cut them into bite-sized sliders perfect for a casual party. Wrapping them in parchment paper makes packing lunches a breeze and keeps everything neat.

Make Ahead and Storage

Storing Leftovers

If you have leftovers (though they rarely last long in my house!), store the tuna mixture and pesto aioli separately in airtight containers in the fridge for up to two days. Keep the bread and avocado separate to prevent sogginess and browning.

Freezing

Because of the fresh avocado and mayonnaise, I don’t recommend freezing the assembled sandwich. However, the tuna mix freezes well on its own for up to 2 months—just thaw overnight in the fridge before use.

Reheating

Reheat bread slices in a toaster or skillet to get them crispy again, then assemble with chilled tuna and aioli. Reheating the tuna mix isn’t necessary, as it tastes best cold or at room temperature.
