Ingredients You’ll Need

Choosing fresh, quality ingredients really shines here. The tuna should be well-drained, and ripe avocados make all the difference by adding creaminess without overpowering the other flavors.

• Pesto: Use a vibrant, good-quality basil pesto—homemade or store-bought works fine.
• Mayonnaise: Combines the aioli and tuna salad, adding creaminess; feel free to use light mayo if preferred.
• Chili crunch: This crunchy, spicy chili oil is a game-changer for a subtle heat and texture.
• Honey: Just a touch to balance the spice with a slight sweetness.
• Lemon juice & zest: Brightens the tuna and aioli, giving the whole sandwich a fresh zing.
• Canned tuna: Drain it really well; I usually press it gently with a paper towel before mixing.
• Dijon mustard: Adds a savory tanginess that’s essential for that classic tuna flavor.
• Garlic cloves: Fresh garlic keeps the sandwich from feeling bland—don’t skip it.
• Capers: Briny little bursts of flavor that wake up the tuna salad.
• Anchovy paste or filets: For that umami depth—trust me, it’s magic when blended smoothly.
• Dill: I love using fresh dill, but dried works if that’s what you have on hand.
• Red onion: Adds crunch and a bit of bite to balance the creamy elements.
• Whole wheat flatbread, sourdough, or focaccia: Toasted to a thin crisp, they add the perfect texture for holding everything together.
• Tomato slices: Look for ripe but firm tomatoes so the sandwich doesn’t get soggy.
• Avocado: One large, perfectly ripe avocado sliced thick for that luscious creaminess.
• Pickled banana peppers (optional): For an extra spicy-briny punch that brightens every bite.

Variations

I love tweaking this recipe depending on mood and season—don’t hesitate to personalize it to your liking. It’s all about making it work for you!

• Vegan Option: Swap the tuna for smashed chickpeas and replace mayo with vegan mayo for a plant-based twist that still hits all those creamy, savory notes.
• Extra Heat: Add more chili crunch or a few dashes of hot sauce in the pesto aioli if you like things really spicy—my husband can’t get enough that way!
• Bread Choices: Try it on a gluten-free pita or a hearty rye bread if you want a different texture, just toast it until crisp to avoid sogginess.
• Fresh Herbs: Experiment with swapping dill for fresh parsley or basil to highlight different flavor profiles.

How to Make Tunacado Sandwich with Spicy Pesto Aioli Recipe

Step 1: Whip Up the Spicy Pesto Aioli

Start by mixing together pesto, mayonnaise, chili crunch, honey, and lemon juice until smooth in a small bowl. Season with salt and pepper to your taste. I usually make this first so those flavors have just a few minutes to meld while I prep the rest. Set it aside, but don’t forget to give it a little taste before assembling; sometimes a pinch more chili crunch or a splash more lemon juice makes all the difference.

Step 2: Blend the Perfect Tuna Salad

Grab a food processor and add the drained tuna, mayo, dijon mustard, lemon zest and juice, garlic cloves, drained capers, anchovy paste or filets, and dill. Pulse until smooth and fluffy—this usually takes about a minute, but don’t hesitate to scrape down the sides to ensure even mixing. When it’s got that whipped, light texture, transfer to a bowl and stir in the diced red onions, salt, and pepper. Taste and adjust seasoning; sometimes a little more lemon juice brightens it up perfectly.

Step 3: Toast Your Bread to Crispy Goodness

Heat 1 tablespoon of oil in a large skillet over medium-high heat. Place two slices of your bread cut side down into the pan, then press gently with a smaller pan or pot to ensure even toasting. Cook for 2 to 3 minutes until golden brown and crispy, then remove and toast the rest. The goal here is a thin crisp edge with a still soft, chewy interior that provides amazing texture contrast to the creamy filling.

Step 4: Assemble Your Tunacado Sandwich Masterpiece

Spread a generous layer of your spicy pesto aioli on each slice of toasted bread, then evenly distribute the whipped tuna salad on two pieces. Layer with slices of ripe tomato and avocado—don’t be shy with the avocado, as it adds that luscious, buttery feeling with every bite. If you love a bit of briny heat, add some pickled banana peppers on top. Close the sandwiches, slice in half, and get ready to impress your taste buds.

How to Serve Tunacado Sandwich with Spicy Pesto Aioli Recipe

Garnishes

I usually keep it simple with extra fresh dill sprigs or a light dusting of cracked black pepper on top. Sometimes I’ll add extra pickled banana peppers on the side for guests who love a bit more heat and tang—it’s a small touch that amps up the experience.

Side Dishes

My go-to sides for this sandwich are simple and fresh: a crisp green salad with lemon vinaigrette, crispy kettle chips, or even a cup of cool cucumber soup on the side. These help keep the meal light but satisfying without competing with the bold sandwich flavors.

Creative Ways to Present

For gatherings, I love to slice these sandwiches into smaller sliders and arrange them on a platter with little picks through the center for easy serving. Adding a colorful side like roasted red pepper mixed olives or marinated artichokes makes the plate pop visually and flavor-wise.

Make Ahead and Storage

Storing Leftovers

If you have leftovers, I store the tuna salad mixture and the aioli separately in airtight containers in the fridge. The bread and fresh avocado are best left separate and assembled fresh to avoid sogginess and browning.

Freezing

I don’t recommend freezing this sandwich assembled because the textures and flavors change—especially with avocado and aioli. However, you can freeze the tuna salad mixture if needed, just thaw in the fridge overnight and give it a good stir before using.

Reheating

Since the sandwich is best fresh, I typically only reheat the bread if needed by popping it in a toaster oven for a couple of minutes. Reheat the tuna salad gently at room temperature if preferred, but avoid microwave heating to preserve texture and flavor.
