Ingredients You’ll Need
What’s magical about this Tuna Arugula Sandwich on Sourdough is the way simple, straightforward ingredients come together to create a vibrant, craveable bite. Each element plays a key role, whether it’s adding crunch, creaminess, or a pop of fresh green.
- Sourdough Bread: Toasted to a golden edge, it provides a hearty base and that signature tang which cuts through the creamy tuna.
- Canned Tuna in Water: Drained well, this is the main source of protein and delivers satisfying, savory substance.
- Light Mayonnaise: Keeps things luscious and moist but not too heavy; you can adjust to taste.
- Dijon Mustard (optional): Adds an extra layer of sharpness and depth—highly recommended for flavor seekers!
- Salt & Pepper: Essential seasonings to boost all the other flavors without overpowering them.
- Fresh Arugula: Offers a peppery bite and lovely color; it transforms the whole sandwich from ordinary to special.
How to Make Tuna Arugula Sandwich on Sourdough
Step 1: Mix the Tuna Salad
Start by adding the drained canned tuna, light mayonnaise, and a spoonful of Dijon mustard (if using) to a medium bowl. Use a fork to gently break up the tuna and fold everything together until well combined. Don’t forget a pinch of salt and some fresh cracked black pepper! This is your moment to taste and tweak, making sure the flavors are just right for you.
Step 2: Toast the Sourdough
Pop two slices of sourdough bread into your toaster or a hot skillet. Toast them until they’re perfectly golden and crisp on the outside, while still tender enough to bite through. The idea is to build up a sturdy foundation that won’t get soggy once you add the tuna salad.
Step 3: Assemble the Sandwich
Spread the tuna mixture generously and evenly across one slice of your freshly toasted sourdough. Don’t skimp here—make sure every bite gets a good helping. Next, lay a big, vibrant handful of fresh arugula right on top of the tuna for a peppery zest and lovely crunch.
Step 4: Sandwich and Slice
Cap it all off with your second slice of sourdough, pressing down gently to keep the filling in place. If you like, cut your Tuna Arugula Sandwich on Sourdough in half—either diagonally for a café-style look or straight down the middle. Serve right away for best texture and flavor.
How to Serve Tuna Arugula Sandwich on Sourdough
Garnishes
A little extra attention to garnish can make your Tuna Arugula Sandwich on Sourdough feel restaurant-worthy. Try sprinkling some flaky sea salt on the arugula just before closing your sandwich. A few thin slices of pickled red onion, a squeeze of lemon, or a touch of cracked black pepper over the top can add even more zing and visual flair.
Side Dishes
This sandwich pairs beautifully with a crisp side salad—think cherry tomatoes, cucumber, and a splash of balsamic. A handful of kettle-cooked chips or a bowl of soup (like tomato or minestrone) make it into a cozy, complete meal. The possibilities are endless, and you can tailor your sides to what you’re craving that day.
Creative Ways to Present
If you want to wow your guests (or just yourself), cut your Tuna Arugula Sandwich on Sourdough into quarters and arrange them on a wooden board with tiny dill pickles and olives. For a picnic or lunchbox, wrap each sandwich half in parchment and tie with twine for a charming touch. You can even toast the assembled sandwich on a panini press for a warm, melty twist.
Make Ahead and Storage
Storing Leftovers
If you find yourself with leftovers, store the tuna mixture separately in an airtight container in the refrigerator for up to three days. Keep the sourdough and arugula separate to maintain their freshness and avoid any sogginess. Just assemble your Tuna Arugula Sandwich on Sourdough when you’re ready to eat for the best results.
Freezing
While freezing the assembled sandwich isn’t recommended (the bread and greens won’t thaw well), you can freeze the plain tuna salad mixture in a sealed container for up to a month. Thaw it in the refrigerator overnight, give it a good stir, and then add your fresh mayo or mustard and arugula when you’re ready to serve.
Reheating
If you’d like your sandwich warm, just toast the bread again or pop the whole assembled sandwich (minus the arugula, if possible) into a panini press or skillet for a couple of minutes. Add fresh arugula afterward for the best crunch and flavor.
FAQs
Can I use a different type of bread?
Absolutely! While sourdough really shines in this recipe, you can easily swap in multigrain, whole wheat, or even a baguette. Just be sure the bread you choose is sturdy enough to hold up to the tuna salad and arugula.
Is there a substitute for arugula?
If arugula isn’t your thing or you don’t have it on hand, you can use baby spinach, watercress, or even crisp romaine. Each green adds its own twist, so feel free to experiment and find your favorite.
What kind of tuna works best?
For the ultimate Tuna Arugula Sandwich on Sourdough, choose a good-quality canned tuna in water, which offers a lighter flavor and texture. If you prefer a richer result, tuna packed in olive oil will also work beautifully.
How do I make it lighter or healthier?
Use Greek yogurt in place of mayonnaise, opt for whole grain sourdough, or add extra arugula for a more veggie-forward take. You can also mix in diced celery or red onion for crunch and extra nutrients.
Can I make the tuna salad ahead of time?
Yes, prepping the tuna salad a day in advance lets the flavors meld together. Keep it in an airtight container in the fridge, and assemble your Tuna Arugula Sandwich on Sourdough just before eating for optimal freshness.
