I Tried Tuna Sandwiches From 17 Popular Sub Chains

What makes a perfect tuna sandwich?

I’ve often wondered this while staring at menu boards across America’s sandwich shops.

So I embarked on a fishy adventure, visiting 17 popular sub chains to find the ultimate tuna creation.

Armed with my appetite and a notepad, I sampled each offering, judging everything from bread freshness to tuna-to-mayo ratio.

The results? Surprisingly varied—and one clear champion emerged.

1. Subway’s Soggy Disappointment

My tuna journey began where most sandwich quests do—at Subway. Their tuna had that unmistakable smell that hits you before the sandwich even arrives. The bread quickly transformed into a soggy mess, collapsing under the weight of overly mayonnaise-heavy tuna.

The vegetables lacked crunch, seemingly wilted from sitting in the display case too long. I couldn’t detect any seasoning beyond mayo, making each bite blend into a monotonous paste. Perhaps most concerning was the texture—suspiciously smooth without any real tuna chunks to speak of.

Those viral “is it really tuna?” controversies suddenly made sense. For a chain with such ubiquity, this was a disappointing start to my tuna tour.

2. Jersey Mike’s Fresh Take

Jersey Mike’s tuna sandwich arrived with a promising appearance—chunky tuna salad nestled in their signature bread that’s crusty outside and pillowy inside. The tuna mixture struck a nice balance between creamy and chunky, with visible celery bits adding welcome texture. Unlike many competitors, they don’t skimp on the protein.

Each bite delivered substantial tuna chunks that actually tasted like the ocean (in a good way). Their “Mike’s Way” addition of onions, lettuce, tomatoes, vinegar, and oil created a pleasant contrast to the rich tuna. The sandwich held together remarkably well without soaking through the bread. Jersey Mike’s clearly puts thought into their tuna prep, elevating it beyond basic lunch counter fare.

3. Jimmy John’s Speed Without Substance

Jimmy John’s prides itself on freaky fast delivery, but speed doesn’t always equal quality. Their tuna arrived in record time, wrapped in their signature paper. The French bread had that distinctive Jimmy John’s chew, which initially impressed me. Unfortunately, the tuna itself was remarkably bland. The mixture lacked seasoning beyond a heavy mayo presence, and I struggled to find much actual tuna texture.

Their vegetables were fresh and crisp—I’ll give them that—but couldn’t compensate for the underwhelming protein. The portion size also left me wanting more. For the price point, I expected a more substantial filling. Jimmy John’s might win the race for speed, but their tuna sandwich finished far from first in flavor.

4. Firehouse Subs’ Smoky Surprise

Firehouse Subs takes a unique approach to their tuna sandwich, serving it hot on toasted sub rolls. The warmth brings out different flavor notes you don’t typically experience in cold tuna. Their bread—steamed before toasting—creates a delightful texture that complements the filling. What sets their tuna apart is a subtle smoky quality that permeates the mixture. I detected hints of dill and possibly a touch of lemon that brightened each bite.

The vegetables maintained their crispness despite the sandwich’s warmth. Firehouse doesn’t overwhelm with mayo, allowing the tuna’s natural flavors to shine through. The portion size impressed me too—generous without being excessive. This was the first sandwich that genuinely surprised me with its thoughtful preparation.

5. Quiznos’ Toasty Tragedy

Remember when Quiznos was everywhere? Their numbers have dwindled, but I tracked one down for this tuna mission. Their signature toasting process seemed promising for a tuna sandwich, potentially adding flavor dimension. The reality proved disappointing.

While the bread had nice crispness from toasting, the heat caused the already mayo-heavy tuna to become uncomfortably warm and oily. The promised spices listed on their menu were virtually undetectable. Texture-wise, their tuna lacked the chunky quality I prefer, instead presenting as an overly processed spread. The vegetables were fresh enough but couldn’t save this sandwich.

Quiznos’ former innovation seems to have faded, leaving behind a forgettable tuna experience.

6. Potbelly’s Comforting Classic

Potbelly Sandwich Shop exudes cozy vibes, and their tuna sandwich continues that homestyle approach. Served on their signature oval bread (I chose multigrain), the sandwich arrived warm with perfectly melted Swiss cheese—an optional add-on I couldn’t resist. Their tuna salad achieves the ideal texture balance—not too chunky yet not suspiciously smooth.

I detected hints of celery, onion, and possibly a touch of relish that added complexity without overwhelming the tuna flavor. The proportions felt just right, with enough filling to satisfy without creating a messy eating experience. Potbelly’s attention to detail extended to the vegetables, which tasted garden-fresh.

The pickle served alongside added a perfect palate-cleansing tang between bites. This sandwich offered a nostalgic, comforting experience.

7. Blimpie’s Blast From The Past

Walking into Blimpie felt like stepping into a sandwich time machine. Their retro vibe extends to their tuna sandwich—a straightforward, no-frills approach that reminds me of school cafeteria days (but better). The tuna mixture had a pleasant tanginess that suggested they might use pickle relish or a touch of mustard in their recipe.

Their bread, while not exceptional, provided a sturdy foundation that held up well throughout the eating experience. Vegetables were standard fare but fresh enough. What Blimpie lacks in innovation, they make up for in nostalgia and value. The portion size impressed me for the price point.

While not revolutionary, their tuna sandwich delivered exactly what you’d expect—a reliable, satisfying option that wouldn’t disappoint a traditional tuna fan.

8. Penn Station’s Hot Mess

Penn Station East Coast Subs takes an unconventional approach by offering their tuna sandwich hot—and I mean really hot. The sub emerges from their oven with bubbly, melted provolone covering a substantial tuna portion on hearty Italian bread. The concept sounds intriguing, but the execution left me conflicted. The intense heat transformed the tuna’s texture into something closer to a casserole than a sandwich filling.

Their tuna recipe includes noticeable black pepper and possibly oregano, creating a unique flavor profile unlike any other chain I visited. Fresh toppings are added after baking, creating a temperature contrast that some might enjoy. While points go to Penn Station for creativity, the hot tuna concept remains divisive—you’ll either love this bold interpretation or find it utterly perplexing.

9. Which Wich’s Customization Champion

Which Wich’s ordering system—checking boxes on a sandwich bag—makes customization their superpower. Their tuna base proved solid: medium chunks mixed with just enough mayo to bind without drowning the fish. The real magic happens with mix-ins and toppings. I opted for their “signature” tuna preparation, which includes diced apple and dried cranberries.

This surprising sweet-savory combination actually worked beautifully, adding brightness to each bite. Their toasted bread maintained structural integrity despite the moisture-heavy filling. Beyond the standard lettuce and tomato, I added cucumber and avocado (for an upcharge). The fresh elements balanced the rich tuna perfectly.

Which Wich may not have the best base tuna, but their customization options allow you to create a personalized masterpiece that stands out from cookie-cutter competitors.

10. Capriotti’s Unexpected Contender

Capriotti’s Sandwich Shop isn’t typically known for seafood—their turkey subs get all the fame—but their tuna sandwich emerged as a dark horse in this competition. The bread immediately stood out: bakery-quality rolls with perfect crust-to-softness ratio.

Their tuna salad contains finely diced celery and red onion that add texture without overwhelming. The mayo ratio struck that elusive perfect balance—enough for creaminess without turning soupy.

A hint of lemon brightened the flavor profile considerably. Capriotti’s doesn’t skimp on portions either. The sandwich arrived stuffed with a generous tuna serving and fresh produce. The provolone cheese option added a subtle richness that complemented rather than competed with the tuna.

This unexpectedly excellent execution proved you shouldn’t judge a sandwich shop solely by its signature items.

11. Ike’s Love & Sandwiches’ Flavor Explosion

Ike’s doesn’t do anything conventionally, and their tuna sandwich proves no exception. Called “Sometimes I’m a Vegan” (despite containing actual tuna), this creation comes on Dutch crunch bread—a game-changer with its crackly, sugar-crusted exterior and soft interior.

Their tuna salad incorporates unexpected ingredients like cranberry sauce and artichoke hearts, creating a sweet-tangy-briny flavor combination that shouldn’t work but somehow does. Ike’s signature “Dirty Sauce” (a garlic aioli baked into the bread) adds another dimension of richness.

The sandwich comes warm with melted provolone, transforming the texture completely. While purists might call this sandwich sacrilege, adventurous eaters will appreciate the bold flavor combinations. Ike’s creates a tuna experience so unique it barely resembles what other chains serve.

12. Lenny’s Grill & Subs’ Generous Portions

Lenny’s Grill & Subs makes one thing clear from the moment they hand you their tuna sandwich: they don’t believe in skimping. The sheer weight of the package tells you you’re getting your money’s worth. Their tuna salad leans toward the chunky side with visible pieces of white albacore mixed with finely diced celery and onion. The mayo presence is noticeable but not overwhelming.

Lenny’s submarine-style rolls deserve special mention—substantial enough to support the filling without becoming a bread overload. The regular size sandwich could easily feed two people, making it a value standout. While their tuna recipe doesn’t reinvent the wheel with unusual ingredients, they execute the classics exceptionally well. Sometimes perfect execution of fundamentals beats flashy innovation.

13. Togo’s Tuna Triumph

California-based Togo’s has a loyal following, and their tuna sandwich demonstrates why. The first bite revealed albacore tuna with minimal mayo—you actually taste the fish rather than just creamy spread. Their preparation includes finely minced celery and red onion that add textural interest.

Togo’s bread deserves special recognition—slightly chewy with a tender crumb that stands up to the filling without getting soggy. I opted for the #16 (tuna and avocado), which proved a winning combination. The avocado’s buttery texture complemented the tuna perfectly.

What impressed me most was the tuna’s freshness—no fishy aftertaste or questionable texture. The portion size hit the sweet spot: generous without being unwieldy. Togo’s clearly prioritizes quality ingredients over gimmicks, resulting in a sandwich that satisfies tuna purists.

14. Erbert & Gerbert’s Quirky Approach

Erbert & Gerbert’s stands out immediately with their unusual bread technique—they remove some of the soft interior (called “the guts“) and place it on top of the sandwich. This creates more room for fillings while reducing bread heaviness.

Their tuna salad features a coarser texture than most chains, with larger tuna chunks that provide satisfying bite. The mayo ratio is conservative, allowing the seafood flavor to dominate. A surprise ingredient—a hint of dill—adds wonderful aromatic notes.

Their vegetable toppings arrive remarkably crisp, and their signature hot pepper blend (optional) adds welcome heat that cuts through the tuna’s richness. The hollowed-out bread technique actually works brilliantly for tuna, preventing the dreaded soggy sandwich syndrome that plagues many competitors. This quirky regional chain delivers an unexpectedly thoughtful tuna experience.

15. Publix Deli’s Supermarket Standout

Supermarket delis rarely compete with dedicated sandwich shops, but Publix defies expectations. Their tuna sandwich on fresh-baked Cuban bread immediately impressed with its presentation—neatly assembled, generously filled, and precisely sliced. The tuna salad achieves ideal consistency—substantial chunks bound with just enough mayo to hold together.

They incorporate finely diced sweet pickles that add tangy contrast without overwhelming. The sandwich artist built perfect proportions of lettuce, tomato, and onion, creating balanced bites throughout.

Most surprising was the value—significantly less expensive than chain competitors while offering superior quality. The bread’s slightly sweet notes complemented the savory filling beautifully. Publix proves that some of the best sandwiches come from unexpected places, not flashy national chains with big advertising budgets.

16. Wawa’s Convenience Store Conqueror

Wawa inspires cult-like devotion in the Mid-Atlantic region, and their tuna hoagie demonstrates why. Ordering via touchscreen allows precise customization—I selected a wheat roll, pepper jack cheese, and their signature herb blend. The tuna itself surprised me with its quality. Rather than the homogeneous paste many quick-service spots serve, Wawa’s version contains identifiable tuna flakes with balanced mayo. Their bread—delivered daily to stores—tastes remarkably fresh for a convenience chain.

What elevates the experience is their vegetable quality and preparation. Everything is sliced to order, resulting in crisp, garden-fresh toppings.

For a place better known for coffee and gas pumps, Wawa delivers a tuna sandwich that outperforms many dedicated sandwich shops. The convenience factor combined with unexpected quality makes this a standout option for tuna lovers on the go.

17. Schlotzsky’s: The Unexpected Winner

Schlotzsky’s circular sourdough buns immediately set their tuna sandwich apart visually. The bread’s tangy flavor profile creates a perfect foundation, complementing the seafood rather than competing with it. Their toasting technique yields a delicate exterior crunch while maintaining interior softness. Their tuna preparation achieves perfection through simplicity—chunks of premium albacore mixed with minimal mayo, black pepper, and finely diced red onion.

No unnecessary fillers or overwhelming spices, just clean, fresh flavors. The sandwich comes dressed with crisp lettuce, ripe tomato, and their signature sauce that adds a slightly sweet, tangy dimension. Every component works in harmony, creating a tuna sandwich greater than the sum of its parts.

The portion size satisfies without overwhelming. After 16 other contenders, Schlotzsky’s emerged as the clear champion—proof that thoughtful execution of quality ingredients beats gimmicks every time.
