I’ll admit it—I’ve always had a soft spot for a good fast-food classic, and Arby’s Beef & Cheddar is high on my list of comfort favorites. That warm, cheesy sauce, the tender roast beef, and that tangy red ranch sauce tucked into a soft onion roll… it’s the kind of sandwich that makes you close your eyes on the first bite.
But let me tell you, recreating it at home has been a game-changer. I get to use fresh ingredients, tweak the flavors exactly how I like them, and skip the drive-thru line. The result? A sandwich that’s not only delicious but also feels like a little kitchen victory every time I pull it together.
What You Need To Make This Recipe
Roast Beef: The star of the show! Thinly sliced deli-style roast beef works best here. It warms up quickly and gives you that signature tender texture that makes the sandwich irresistible.
Onion Rolls: These soft, slightly sweet rolls are the base of the sandwich. The subtle onion flavor enhances the beef and cheese without overpowering them.
Cheddar Cheese Sauce: Creamy, melty, and rich, this sauce is what gives the sandwich its indulgent personality. Using real cheddar makes all the difference.
Red Ranch Sauce: This is Arby’s signature tangy-sweet sauce that adds a unique twist. You can whip up your own with a mix of ketchup, mayo, and a few seasonings.
Butter: A light brush of butter on the rolls before warming them adds richness and helps them toast up beautifully.
Ingredients List
- 1 lb thinly sliced roast beef
- 4 onion sandwich rolls

How to Make Arby’s Beef & Cheddar Copycat
Step 1: Warm the Roast Beef
Place your sliced roast beef in a skillet with a splash of water or beef broth. Warm it gently over low heat until it’s hot and tender, but be careful not to overcook—it should stay juicy.
Step 2: Toast the Rolls
Split the onion rolls in half and spread a thin layer of butter on the cut sides. Toast them lightly in a skillet or under the broiler until golden and slightly crisp.
Step 3: Prepare the Cheddar Sauce
If you’re making your own, melt butter in a saucepan, whisk in flour, then slowly add milk and shredded cheddar until smooth. Keep it warm and silky for easy drizzling.
Step 4: Assemble the Sandwich
Spread red ranch sauce on the bottom half of each toasted roll. Pile on the warm roast beef, then spoon a generous layer of cheddar cheese sauce over the top. Cap it off with the top roll and serve right away.
Tips for Making this Recipe
- Warm the beef gently to avoid drying it out.
- If you can’t find onion rolls, use regular sandwich buns and sprinkle some onion flakes on top before toasting.
- Homemade cheddar sauce tastes best, but a high-quality store-bought version works when you’re short on time.
- Adjust the tanginess of the red ranch sauce to your liking—more ketchup for sweetness, more vinegar or hot sauce for punch.
- Serve with curly fries or potato wedges to really bring home the classic fast-food feel.
FAQs
Can I make this ahead of time?
You can prep the sauces and toast the rolls ahead, but assemble the sandwich just before serving so the bread doesn’t get soggy.
What’s the best cheese for the sauce?
Sharp cheddar gives the richest flavor, but you can mix in American cheese for extra creaminess.
Is there a substitute for onion rolls?
Yes! Regular hamburger buns or brioche rolls work well—just add a sprinkle of dried onion flakes for flavor.
Can I use leftover roast beef?
Absolutely. Just slice it thinly and warm it gently with a bit of broth to keep it juicy.
