Arby’s is already famous for its roast beef sandwiches and curly fries, but there’s a whole hidden world of menu items most people never get to try. These off-menu creations are real, and you can order them just by asking the right way at the counter.
Whether you’re a longtime Arby’s fan or just getting curious, these secret options are worth knowing about. Get ready to upgrade your next fast food run in a seriously delicious way.
1. Meat Mountain Sandwich

Imagine every meat Arby’s has in the kitchen piled onto a single sandwich. That’s exactly what the Meat Mountain is — roast beef, turkey, ham, brisket, bacon, and chicken tenders all stacked between two buns in one glorious tower of protein.
It started as a joke menu poster, but fans demanded it for real. Ask for it by name and most locations will build it for you.
Fair warning: you might need both hands and a serious appetite to tackle this beast.
2. Double Stacked Reuben

Classic Reubens are already a crowd-pleaser, but Arby’s secret version takes things up a notch with double the corned beef. Melted Swiss cheese, tangy sauerkraut, and creamy Thousand Island dressing round out every bold, satisfying bite.
The marble rye bread gets toasted just right, giving it that signature crunch. If you’re the kind of person who always wants more meat, this upgrade was basically made for you.
Just ask the staff to double up the corned beef when ordering.
3. Bacon Beef ‘n Cheddar

Arby’s Beef ‘n Cheddar is already a fan favorite, but adding crispy bacon turns it into something next-level. The smoky, salty crunch of the bacon plays perfectly against the warm cheddar sauce and tender roast beef.
All of it sits on a soft toasted onion roll that brings the whole thing together. This is one of those off-menu tweaks that feels so obvious you’ll wonder why it’s not on the regular menu.
Requesting it is simple — just ask for bacon added to your Beef ‘n Cheddar.
4. French Dip Max

The regular French Dip at Arby’s is solid, but the Max version is on another level entirely. You get a full seven ounces of roast beef — that’s double the standard amount — plus an extra slice of Swiss cheese melted right on top.
A soft sub roll holds everything together, and the au jus dipping sauce on the side makes each bite even more flavorful. It’s the kind of upgrade that turns a good lunch into a genuinely memorable meal.
Ask for the French Dip Max and watch the magic happen.
5. Ultimate BLT

Eight strips of pepper bacon. Let that sink in for a moment.
The Arby’s Ultimate BLT isn’t playing around — it’s a full-on bacon lover’s dream stacked with fresh lettuce, ripe tomatoes, and creamy mayo on toasted honey wheat bread.
The pepper bacon adds a slightly spicy kick that sets it apart from your average BLT. It’s surprisingly simple as a concept, but the execution is anything but ordinary.
This one is perfect for anyone who thinks regular sandwiches just never have enough bacon.
6. Loaded Italian Sandwich

Not everyone knows Arby’s can go full Italian-deli mode when you ask nicely. By combining their deli-style meats — think ham, salami, and pepperoni — with provolone and banana peppers, you get a sandwich that feels like a trip to your favorite sub shop.
The key is asking staff to layer the meats on a toasted hoagie-style roll and add whatever toppings speak to you. Availability depends on your location, but adventurous eaters swear by this one.
It’s bold, hearty, and completely worth the ask.
7. Arby’s Club Sandwich

Who says fast food can’t do a proper club sandwich? At Arby’s, you can request a stacked club-style creation using turkey, roast beef, Swiss cheese, bacon, lettuce, and tomato — all piled onto toasted bread for a deli-quality experience.
The combination of meats gives it a rich, layered flavor that feels more upscale than your usual drive-through order. It’s a surprisingly satisfying option for anyone who wants variety without committing to just one protein.
Describe the build to your server and they’ll usually put it together without any trouble.
8. Jalapeño Roast Beef Sandwich

For spice lovers, Arby’s roast beef gets a fiery makeover with the addition of fresh jalapeños, pepper jack cheese, and a drizzle of hot sauce or spicy mayo. The heat builds slowly at first, then hits you right where it counts.
It’s a clever remix of a classic that adds serious personality to every bite. Staff can usually pull this together easily since most ingredients are already on hand.
If your usual order feels a little too tame, this jalapeño twist is exactly what you’ve been missing.
9. Triple Stack Roast Beef

Some days, a regular roast beef sandwich just doesn’t cut it. The Triple Stack fixes that problem by tripling the roast beef and layering it with cheddar and red ranch sauce inside a toasted bun that somehow holds it all together.
It’s a nostalgic, no-frills order that celebrates what Arby’s does best — great roast beef, done right. This one works especially well if you’re coming in hungry after a long day.
Just ask for three portions of roast beef and let the rest fall into place.
10. Curly Fry Beef ‘n Cheddar Mash-Up

Here’s a quirky one that sounds wild but actually works brilliantly — stuffing Arby’s curly fries directly inside a Beef ‘n Cheddar sandwich. The crispy, seasoned fries add crunch and a peppery punch that transforms the whole eating experience.
It’s the kind of food hack that feels almost rebellious in the best possible way. Fans who’ve tried it say it’s hard to go back to eating them separately after this.
Ask for your curly fries on the side, then load them right into your sandwich at the table.
