A speedy, homemade version of Arby’s iconic Beef N' Cheddar — thinly sliced roast beef, creamy American cheese sauce, tangy house-style sauce, and soft onion buns. Ready in under 10 minutes.

This Copycat Arby's Beef N' Cheddar has been my fast-food comfort in a pinch, perfect for nights when the craving for a hearty sandwich hits but the idea of leaving the house does not. I first pulled this together on a busy weeknight using deli-sliced roast beef from the grocery counter and a handful of pantry staples. The result? A sandwich that hits the same savory, slightly sweet notes as the original: warm, tender beef, a gooey, silky American-style cheese sauce, and that tangy, bright sauce that cuts through the richness. It became an instant favorite with my family and a regular contender for last-minute dinners.
What makes this version special is the balance between speed and flavor. With only a few minutes of active prep and common ingredients like ketchup, milk, and American cheese, you get multilayered taste and satisfying texture. The onion rolls provide a soft, slightly sweet cradle for the beef and cheese, while the homemade signature sauce brings acidity and a hint of savory spice. This is a sandwich I trust to please picky eaters and grown-up palates alike, and it always brings back memories of sharing a quick meal after a busy day at the soccer field.
I remember the first time I made this for my sons; they declared it indistinguishable from Arby's and asked for it two nights in a row. The confidence that comes from recreating a fast-food favorite at home — with control over quality and portions — is why this sandwich lives in our regular rotation.
My favorite aspect is how quickly the components come together without sacrificing the layered flavors that make the original memorable. I have a vivid memory of bringing these sandwiches to a small picnic; they stayed satisfyingly warm in an insulated bag and received unanimous approval from neighbors who declared them as close to the real thing as any homemade attempt.
To store, separate the components: keep the warm roast beef in an airtight container and the cheese sauce in a small jar, both refrigerated for up to two days. The signature sauce will last up to seven days and can be spooned onto toasted buns at serving time. Avoid assembling fully before storing as the buns will absorb moisture and become limp. For freezing, place only the beef in a freezer-safe bag for up to three months; thaw overnight in the refrigerator and reheat gently in a skillet.
If you prefer a less processed approach, substitute shredded sharp cheddar for the American cheese; use 1 cup shredded cheddar and 2 tablespoons cream to create a smooth sauce. For a lower-sodium option, purchase low-sodium or reduced-sodium deli roast beef and use a reduced-sodium ketchup for the signature sauce. Vegetarian diners can use thinly sliced seared mushrooms or plant-based deli slices and a dairy-free cheese alternative; expect a different mouthfeel but similar satisfaction.
Serve these sandwiches with classic frozen curly fries warmed until crispy or alongside a bright cabbage slaw to cut the richness. Garnish with a few thinly sliced dill pickles for acidity or a small handful of microgreens for color. For a heartier plate, add a side cup of tomato soup or a crisp apple and fennel salad to balance the savory notes.
The Beef N' Cheddar is an American fast-food classic associated with a roast beef sandwich tradition that emphasizes thin slicing and bold, saucy flavors. Regional sandwich shops have long offered similar compositions, pairing warm roast beef with melted cheese and a tangy sauce. Recreating this at home taps into midcentury deli techniques and the modern convenience of deli counters, blending nostalgia and practicality.
In colder months, bulk up the sandwich with caramelized onions and a smear of roasted garlic aioli for a cozy edge. In summer, keep it lighter by using a tangier sauce with a splash of apple cider vinegar and pairing the sandwich with a seasonal corn salad. Swap the onion bun for a lighter roll or whole-grain bun in spring for fresher contrast with garden salads.
Make the signature sauce and the cheese sauce ahead and store separately in airtight containers. Pack the warmed beef in a thermal container if you are transporting lunches, and toast buns briefly just before serving. For batch cooking, multiply the sauce quantities and reheat gently on low, whisking to reincorporate smoothness. Portion into microwave-safe containers for quick reheats at work.
Bringing this fast-food favorite into your kitchen is both satisfying and practical. With a few smart shortcuts and attention to heat and texture, you can recreate the savory-sweet balance of the original in minutes and make it your own.
Ask the deli to slice the roast beef paper-thin for the best texture and mouthfeel.
Keep the cheese sauce on very low heat and stir constantly to prevent it from separating.
Toast the buns lightly to create a barrier that keeps them from getting soggy from the sauce.
