Sub Culture

You can tell what part of the Northeast you are in by the way folks order their crusty, meat-filled, elongated sandwiches. In Philadelphia, it’s a hoagie. In New England, you’ll hear the term grinder (as in, with bread so crusty you need to grind your teeth in it to take a bite). In certain parts of Boston, you can still order a spuckie, a shortened version of spuccadella, an early 20th century Italian-American word for a long, crusty, split roll. In New York, you’ll dig into a hero (a term credited to New York Herald Tribune writer Clementine Paddleford’s 1936 declaration that one “had to be a hero to eat the whole thing”). Cross the Hudson to New Jersey and most folks will just ask for a sub. And in Maine, it’s simply an Italian.

Whatever you call it, the basic idea is the same: a long, crusty, side-split roll piled with Italian-style cold cuts—salami, capicola, soppressata, prosciutto, ham, mortadella, provolone—layered with shredded lettuce, tomato, onion, maybe a few hot pickled peppers, and a drizzle of oil and vinegar. It’s a sandwich that was designed and built for workers at shipyards and factories to grab and wolf down on their lunch breaks. A meal for people who needed something cheap, hearty, and easy to eat with one hand.

The story of the Italian sub, like so many great American foods, begins with immigrants. In the early 1900s, Italian grocers in coastal cities began stuffing crusty rolls with cured meats and cheese for dockworkers and millhands. In Portland, Maine, Giovanni Amato started selling “Italians” from a cart near the wharves. Around the same time in Paterson, New Jersey, Dominic Conti was offering what he called submarine sandwiches—the name, he said, inspired by a vessel he saw in a museum. By the 1940s, the “sub” had spread up and down the East Coast, with every city giving it a new name and personality.

Here in Seattle, on the opposite side of the continent, there’s no shortage of good-enough-to-hit-the-spot subs, but very few excellent ones. My favorite comes from Post Alley Pizza—a little downtown spot that serves some of the finest slices of pizza in town, and whose sandwiches should not be overlooked. Their version is everything an Italian should be: bold, balanced, messy, but controlled, with a range of flavors and textures that cover all the bases—salty cold cuts, a hot pepper spread (enhanced with anchovies), sharp cheese, bracing bitter greens, and plenty of good olive oil and vinegar, all masterfully constructed on crusty, chewy, sesame seed-coated hoagie rolls baked in their pizza oven.

Thankfully, I don’t have to trek across the country or even down to Post Alley to enjoy one. The ingredients are all readily available at the supermarket, and it takes no cooking and very little time to construct one.

A perfect Italian sub is less a recipe than an act of assembly and restraint. Here’s how I build one from the bread up.

Let’s Roll

A good Italian starts, as all good sandwiches do, with the bread. It has to be sturdy and crusty enough to stand up to oil, vinegar, and the collective moisture of its fillings, but still soft enough to yield when you bite through it. I like a roll that crackles on the outside and has some chew within, with a decent amount of density. If you’ve got a good local bakery or the in-store bakery at your Supermarket makes a decently crusty baguette or Italian loaf, that should do you. Even a great Vietnamese banh mi roll will work in a pinch.

The split is a matter of philosophy: some folks cut all the way through, others hinge it so it opens like a book. I’m firmly in the hinge camp—hinging keeps everything tucked neatly inside and allows you to layer more deliberately. As for scooping out the bread, that depends on the loaf. If it’s soft and fluffy, skip the scoop—the bread can compress as you close and press the sandwich; if it’s a denser, crustier loaf (my preference), I like to scoop out a bit of the inside to make room for the fillings. A good drizzle of olive oil (or a smear of pickled pepper spread) on the cut face adds richness and protection from sogginess—much better than mayo, which, as much as I love mayo, doesn’t belong on an Italian sub.

Meat Your Maker

Next come the meats and cheese, the structural foundation and flavor backbone. They should always be thinly sliced—paper-thin, if possible. That way they can be stacked and shingled without becoming overwhelming, and, more importantly, they can be bitten through cleanly. The second-worst thing that can happen while eating an Italian sub is when your teeth pull out a slice of too-thick-salami, threatening the structural integrity of the whole affair in the process. (The worst thing that can happen? I leave that to your imagination).

I’ve had OK luck finding extra-thin pre-sliced cold cuts in fancier deli cases, but for the best results, head to the deli counter and ask the folks there to slice it fresh for you, as thin as they possibly can.

The best Italian subs mix textures and flavors: a spicy, fatty salami or soppressata; something rosy and tender like capicola or mortadella; and some ham for sweetness (cooked ham or raw ham like prosciutto will both work). Sharp provolone ties it together with just enough bite.

Stack to the Future

When it comes to stacking, there is, unsurprisingly, some debate. My former colleague Andrea Geary, over at Cook’s Illustrated once wrote about “air” as an essential sandwich ingredient (paywalled link), suggesting that gently folding the cold cuts to incorporate air pockets improves the eating qualities of the sandwich. On the other hand, my friend Ethan Chlebowski over on his website Cook Well, suggests the opposite: an Italian sub should be compact and compressed.

For me, compression wins because it lets the flavors merge while keeping the structure clean. Air might make for a prettier cross-section, but I’m not eating this thing with a jeweler’s loupe. The meat and cheese layer in a great sub should be compact and compressed, like a neutron star of flavor. It should have a satisfying moment of resistance before it yields.

I start with a foundation of cheese, then add my meats in thin, overlapping layers that cover both sides of the opened bread to form a cradle for the vegetables. Shingling the meat like this provides a moisture barrier so that the dressed greens don’t come into direct contact with the bread, which can cause it to turn soggy (or worse, fall apart).

The Bitter (Greens) Truth

The vegetable layer is where personality shows. Some regions stick to iceberg lettuce and tomato; others add onions, pickles, peppers, or even olives. For the greens, I take a cue from Post Alley Pizza and use a mix of shredded lettuce and bitter greens—chicory, endive, or radicchio—tossed directly with thinly sliced red onion and dressed, like a salad, with really good extra-virgin olive oil, red wine vinegar, salt, black pepper, and oregano. That bite of bitterness and acidity cuts through the fat and salt of the meats.

In a pinch, you could go with just iceberg lettuce (but that would be... radicchio-less).

For tomatoes, I avoid extra-juicy farmer’s market tomatoes (save those for BLTs or tomato sandwiches), instead opting for firm, not-too-ripe Romas; they give you that tomato flavor without the gush of juice that turns a sandwich into a sponge.

Finally, I love a good pickled pepper on my hoagie. You can add a swipe of Calabrian chili paste or a spoonful of hot giardiniera, banana peppers, or even pickled jalapeños, but I like to use Mama Lil's, a local brand of pickled Hungarian goathorn peppers that, like a young goat, start out sweet but end with a swift kick.

Wrap It Up (and Let It Rest)

Once all the meats, cheese, and vegetables are added, I close the sandwich, using the back of a bread knife to press everything towards the hinge so that the bread can envelop it completely. Finally, the last step is the one most people rush past: wrapping and resting. Once assembled, the sandwich needs to sit, tightly wrapped in paper or foil, for a good five to ten minutes. This gives the oil and vinegar time to mingle, the bread to soften slightly, and the flavors to unify. The Italians call it riposo—rest—and it’s important.

Just like a steak needs to rest so its juices redistribute, a sandwich needs a moment for its fillings to settle into equilibrium. Cut it too soon, and you lose the cohesion that makes a truly great Italian sub more than the sum of its parts.

Imagine yourself walking home from the deli down the street before unwrapping your sandwich up and taking a bite. That’s the timeframe to aim for. 

At its best, a great Italian sub isn’t just a sandwich—it’s a blueprint for balance and restraint. They're a cross-section of texture and flavor that reward patience and precision. Whether you call it a sub, hero, hoagie, grinder, spuckie, or Italian, what matters is that moment after the rest, when the bread has softened just enough, the oil has mingled with the vinegar, and your stomach grumbles have reached maximum volume.

Now, cut it in half to reveal the cross-section (an Italian doesn’t taste right when you eat it whole), take a deep breath, admire your work, exhale, and dig in.

Recipe: The Perfect Italian Sub

A great Italian sub is all about engineering: sturdy bread, precise layering, and patience. The key is creating barriers that keep moisture where it belongs—olive oil and vinegar in the greens, not in the bread. Thinly sliced meats and cheese form a compact, shingled core that stays cohesive and biteable. Dressed radicchio and iceberg add crunch, acidity, and a bracing bitterness. A short rest after wrapping lets everything compress into a unified whole. No heat, no tricks—just balance and structure.

Every recipe I publish here is personally tested, tasted, and approved.

What I love about this recipe:

Hinging and scooping the bread makes room for fillings and allows you to compact the sandwich.

A mix of paper-thin cold cuts and cheese gives you a range of flavors without letting the sandwich get too tough.

Shingling the ingredients protects the bread from the juicy seasoned vegetable layer.

Resting the sandwich allows for the flavors to meld, the bread to soften slightly, and the layers to compress.

Yield: 1 large sandwichActive Time: 10 minutesTotal Time: 15-20 minutesNotes: Use a good, crusty loaf such as a baguette, supermarket-style Italian bread, a sesame loaf, or a Vietnamese banh mi roll.

Ingredients

For the sandwich:

1 crusty Italian roll (about a 16 inches/40cm long), sesame-seeded if desired (see note)

Extra-virgin olive oil, for drizzling

2 tablespoons (30ml) pickled pepper spread or Calabrian chile paste (optional)

3 ounces (90g) sharp provolone, thinly sliced

2 ounces (60g) Genoa salami, thinly sliced

2 ounces (60g) soppressata or hot salami, thinly sliced

2 ounces (60g) capicola or mortadella, thinly sliced

2 ounces (60g) prosciutto or cooked ham, thinly sliced

For the dressed greens:

1 cup (about 2 ounces/60g) shredded iceberg lettuce

1 cup (about 2 ounces/60g) shredded bitter greens (such as radicchio, chicory, or endive)

¼ small red onion (about .5 ounces/15g), very thinly sliced

2 tablespoons (30ml) extra-virgin olive oil

1 tablespoon (15ml) red wine vinegar

½ teaspoon (1g) dried oregano

Kosher salt and black pepper

For assembly:

1 medium Roma tomato, sliced thin

Hot or sweet pickled peppers (optional)

Method

1. Prep the bread.

Slice each roll lengthwise, leaving a hinge along one long edge so it opens like a book.If the interior crumb is soft and fluffy, skip the scoop; if it’s dense, scoop a little out to make space for the fillings. Drizzle the cut sides lightly with olive oil, and optionally smear with some hot pepper spread.

2. Build the base.

Line the bottom half with cheese slices—this creates a moisture barrier between the bread and the dressed greens. Layer the meats on top, shingling them in thin, overlapping folds so they form an even layer that covers both sides of the opened loaf. Aim for compression, not bulk: press the layers gently to compact them into a cohesive mass—your “neutron star of flavor.”

3. Make the dressed greens.

In a mixing bowl, combine shredded lettuce, bitter greens, and onion. Drizzle with olive oil and red wine vinegar, sprinkle with oregano, and season with salt and pepper. Toss until evenly coated—think of it as a lightly dressed salad that will bring acidity and crunch to the sandwich.

4. Add the vegetables.

Add a layer of tomatoes along one side of the sandwich. Season lightly with salt and pepper, then spread the dressed greens in a line down the center of the sandwich. Fold the roll closed, using the back of a long bread knife or the handle of a wooden spoon to press everything toward the hinge, allowing the bread to completely envelop the fillings.

5. Wrap and rest.

Tightly wrap each sandwich in parchment paper or foil. Let it rest 5 to 10 minutes at room temperature.

6. Eat like a hero.

Slice the sandwich in half through the wrapper, and eat, sharing it if you'd like.
