- 1 lb deli-style roast beef: Choose thinly sliced, high-quality roast beef for tender, juicy layers.
- 1 can Ricos Premium Cheddar Cheese Sauce (15 oz): Creamy and cheesy, this sauce delivers the signature melt that makes the sandwich irresistible.

How to Make DIY Arby’s Roast Beef Cheddar Sandwiches with Curly Fries Recipe
Step 1: Preheat and Prepare the Roast Beef
Start by warming your oven to 250°F. Wrap your deli-style roast beef in foil and place it on a baking sheet. Heating it slowly like this for about 8 to 10 minutes ensures the meat stays juicy and doesn’t dry out, which is key to that melt-in-your-mouth texture you want.
Step 2: Heat the Cheddar Cheese Sauce
While the beef warms, pour the cheddar cheese sauce into a saucepan and heat it over medium-low heat. Stir occasionally until the sauce is smooth and melty, perfect for drizzling generously over your warm roast beef later on. This step fills your kitchen with that amazing cheesy aroma that sets your taste buds to full alert.
Step 3: Toast the Buns
Next, give those onion sandwich buns a quick toast. Whether you use a skillet or the broiler, just 1 to 2 minutes until lightly golden is enough. This adds a slight crispness without overpowering the softness inside, creating a perfect sandwich structure to hold all your delicious fillings.
Step 4: Cook the Curly Fries
Follow the package directions to bake the curly fries, usually around 20 to 25 minutes at 425°F. The result? Crunchy, perfectly seasoned curls that steal the show as the ultimate sidekick for your roast beef sandwich.
Step 5: Assemble Your Sandwich
Place the warm roast beef on the bottom half of each toasted bun, then drizzle generously with the warm cheddar cheese sauce. Finish with the top bun, gently pressing to let the flavors meld together. This hands-on step is where everything comes alive—so take a moment to appreciate that beautiful melty cheese cascading over tender roast beef before digging in!
Step 6: Serve with Curly Fries
Serve your freshly assembled DIY Arby’s Roast Beef Cheddar Sandwiches alongside a hearty pile of those crispy curly fries. The combination of textures and flavors makes for an incredibly satisfying meal that will have everyone asking for seconds.

Garnishes
To elevate your sandwich, consider adding sautéed onions or pickles for an added tangy crunch. A light handful of shredded lettuce can add freshness and color. These simple garnishes don’t overshadow the star ingredients but complement the flavors beautifully.
Side Dishes
Besides curly fries, a crisp garden salad or coleslaw works wonderfully to balance this hearty sandwich. A cool slaw with a hint of vinegar cuts through the richness of the cheese sauce and roast beef, making every bite feel balanced and fresh.
Creative Ways to Present
If you’re hosting, serve the sandwiches open-faced on a wooden board with small ramekins of extra cheddar sauce for dunking. You can also arrange curly fries in a cone or mini basket for a fun twist. Presentation like this makes your DIY Arby’s Roast Beef Cheddar Sandwiches with Curly Fries Recipe feel restaurant-worthy and exciting to dig into.
Make Ahead and Storage
Storing Leftovers
Wrap leftover sandwiches tightly in foil or plastic wrap and store them in the refrigerator for up to 2 days. Keep the curly fries separate in an airtight container to help preserve their texture as much as possible.
Freezing
The roast beef and buns freeze well individually if you want to prepare ahead, but it’s best to avoid freezing assembled sandwiches to maintain the best taste and texture. Freeze your cheese sauce in a sealed container for up to a month, then gently reheat.
Reheating
Reheat the roast beef wrapped in foil in a low oven to keep it tender. Gently warm the cheese sauce on the stovetop, stirring often. For curly fries, a quick toss in a hot oven or air fryer will revive their crispiness perfectly without sogginess.
FAQs
Can I use a different type of cheese sauce?
Absolutely! While Ricos Premium Cheddar Cheese Sauce mimics the classic flavor best, you can experiment with homemade cheese sauce or other creamy varieties to suit your taste.
Is there a way to make homemade curly fries?
Yes! If you’re feeling adventurous, spiralize potatoes yourself and season with similar spices before baking or frying. It’s a fun way to personalize your DIY Arby’s Roast Beef Cheddar Sandwiches with Curly Fries Recipe.
Can I substitute roast beef with another meat?
While roast beef is traditional for this sandwich, thinly sliced turkey or ham can work as tasty alternatives for a different twist.
How long does this recipe take from start to finish?
The entire meal comes together in about 30 minutes, making it a quick and satisfying option for weeknights or casual gatherings.
What drink pairs well with this meal?
A cold soda, iced tea, or even a robust beer pairs beautifully with the rich flavors of the roast beef and cheddar sauce while balancing the seasoned fries.
