An easy, faithful copycat of Arby's Beef 'N Cheddar — thinly sliced roast beef, cheesy sauce, and a tangy signature dressing assembled on onion buns for a fast, satisfying sandwich.

This Copycat Arby's Beef N' Cheddar is my at-home shortcut to a nostalgic fast-food favorite. I fell in love with the original as a teenager: the warm, tender roast beef folded into an onion roll, a creamy American cheese sauce pooling over the meat, and that slightly sweet, tangy dressing tying everything together. I recreated it after a long week when I wanted the exact same flavors without leaving home. The result? Comforting, quick, and remarkably close to the real thing — perfect for a busy weeknight or an indulgent weekend lunch.
I first tested this version after asking my deli to slice a roast beef extra thin. The technique is simple: warm the meat gently so it stays juicy, melt the cheese into a smooth sauce with a splash of milk, and whisk a homemade copy of Arby's signature dressing that brightens the sandwich. What makes it special is the balance: tender beef, creamy cheese, and a sauce with a little tang and garlic. It’s also fast — you can have four sandwiches ready in under 10 minutes, which makes it my go-to when friends drop by unannounced.
I served this to my partner and our kids the first time I tried the homemade dressing — everyone insisted it tasted like the real Arby's. The thin slices heat through quickly and remain tender under the cheese sauce. I love that one small technique — placing a lid on the skillet to steam the meat briefly — makes a big difference in juiciness without overcooking.
My favorite part is the cheese sauce — when it’s velvety, it mimics the diner pour-over that makes the sandwich uncanny. We once hosted a game night and made a double batch of sauce; friends kept coming back for more and compared it to the chain's version. Cooking the beef briefly under a lid preserves juices and keeps the texture tender, which is the trick for making this taste authentic at home.
Store leftover roast beef in an airtight container in the refrigerator for up to 3 days. Keep the cheese sauce in a separate sealed jar; it will thicken when chilled — reheat gently in a small saucepan over low heat with a splash of milk to bring it back to pourable consistency. Onion buns keep best at room temperature for a day; for longer storage freeze them in a zip-top bag and thaw on the counter before assembling. When reheating the assembled sandwich, use a 325°F oven for 6 to 8 minutes to warm through without drying, covering the top loosely with foil.
If you don’t have American cheese, Velveeta melts extremely smoothly and is the closest processed-cheese alternative; shredded mild cheddar works too but will be slightly less creamy. For a dairy-free version, use a dairy-free cheese that melts well and swap milk for a plant-based milk with neutral flavor. If you want to reduce sodium, purchase low-sodium deli roast beef and low-sodium ketchup; note the flavor will be milder, so increase aromatic spices like a pinch more garlic powder. Use brioche buns for a richer finish or plain potato rolls if you prefer less onion flavor.
Serve these sandwiches with classic curly fries to evoke the Arby's experience, or pair with a crisp green salad to balance the richness. For a loaded plate, add pickles or thin-sliced red onions for brightness, or a side of coleslaw for crunch. Garnish with a sprinkle of cracked black pepper over the cheese and a light brushing of melted butter on the bun before toasting to add shine and flavor. These sandwiches also pair well with a cold iced tea or a crisp lager.
The original Beef 'N Cheddar is a signature menu item from a major American sandwich chain known for roast beef and fast-service sandwiches. The combination of warm roast beef and a creamy processed-cheese sauce reflects mid-20th century American tastes that favored convenience and comforting textures. Many regional delis and diners developed similar melted-cheese-over-roast-beef plates, and this copycat version celebrates that nostalgic flavor profile while letting you control ingredients at home.
In cooler months, add a smear of horseradish mayo for warming heat, or swap the signature sauce for a roasted pepper spread in summer to keep the sandwich bright. Fall is a great time to serve with roasted root-vegetable hash on the side. For holiday gatherings, cut sandwiches into sliders and serve on a platter with extra dipping sauce for guests. Lighten it in spring by using mixed greens and a lighter cheese sauce with milk substituted by half-and-half for richness without heaviness.
For make-ahead lunches, portion meat into individual containers and ladle cheese sauce into small jars. Toast buns lightly just before serving to avoid sogginess. If preparing for a crowd, warm the roast beef in a large covered skillet or on a sheet pan in a low oven, then assemble plates assembly-line style. Use insulated containers to keep assembled sandwiches warm for short transport, and pack sauce separately in a leak-proof jar.
Bringing this sandwich home means you can recreate the fond memories of a favorite chain while making small improvements — better bread, fresher meat, and a sauce tuned to your taste. Try it once and you’ll see why it’s a fast and satisfying pick-me-up.
