Jimmy John’s Gargantuan Ingredients
The Jimmy John’s Gargantuan stands out because it combines five different proteins.
Salami
Salami adds a rich, salty, and savory flavor. It also contributes protein, fat, and sodium.
Capocollo
Capocollo is a seasoned Italian-style meat that adds a bold flavor to the sandwich. It pairs with the salami and other meats to create the Gargantuan’s signature deli-style taste.
Turkey
Turkey provides a milder flavor and adds another source of protein.
Roast Beef
Roast beef adds a hearty, beefy taste and helps make the sandwich more filling.
Ham
Ham adds a familiar savory flavor and completes the five-meat combination.
Provolone Cheese
Provolone provides a creamy and slightly tangy flavor. It also adds protein, fat, and saturated fat.
Fresh Vegetables
The standard Gargantuan includes:
- Onion
- Lettuce
- Tomato
These vegetables add crunch, moisture, and freshness to balance the rich meat and cheese combination.
Mayo
Mayo adds creaminess and flavor. It also contributes calories and fat.
Oil and Vinegar
Oil and vinegar provide a tangy, seasoned flavor. The oil also adds calories and fat.
Oregano-Basil
The oregano-basil seasoning adds an Italian-inspired herbal flavor.
The complete combination creates a large sandwich with layers of meat, cheese, vegetables, and bold seasonings.

How Big Is the Gargantuan®?

The 16-inch version is especially large and often shared between two people.
This sandwich is known for being one of the most filling items on the entire menu.
Pro-Level Customization: “The Secret Menu”
If the Gargantuan isn’t enough for you, or if you want to balance the saltiness, try these veteran moves:
- “Make It Hot”: In 2026, toasting the Gargantuan has become the preferred way to eat it. The heat renders the fats in the salami and capocollo, creating a much richer experience.
- Add Jimmy Peppers®: The spice and acidity of the peppers are necessary to cut through the richness of five different meats.
- The “No Guts” Request: If you’re ordering the 16-inch Giant, ask for “No Guts” (scooping out the bread). This keeps the sandwich from becoming impossibly wide and ensures you can actually fit it in your mouth.
Is the Gargantuan® Available as an Unwich®?
Technically yes, but due to the large amount of meat, it may be difficult to wrap fully in lettuce. Most customers order it on bread because the sandwich is very large and heavy.
Who Should Order the Gargantuan®?
The Gargantuan is ideal for:
- Big appetites
- Meat lovers
- Sharing between two people
- Customers who want maximum protein
- People looking for a very filling meal
If you want a lighter option, smaller sandwiches or wraps may be better.
