This dish is wonderful for holidays, weekend dinners, or just when you're looking for something a bit different to throw into the weekly routine. With only seven ingredients, it's not daunting and can be marinated the night before, to make for an easier cooking process.

The marinade of soy sauce, sugar, garlic, thyme, and ginger helps tenderize and flavor the beef. It does double duty since it's used to baste the beef in the last 30 minutes of cooking. You can marinate the beef for as little as four hours or up to overnight, but don't leave the roast beef in the marinade much longer than eight hours, since it will eventually turn the texture of the beef mushy.

Serve roast beef with classic vegetable sides like mashed or roasted potatoes, glazed carrots, and green beans. Homemade rolls would also be a real treat.

How Long Can I Marinate Beef?

Marinating adds flavor and can help to tenderize tough cuts of beef, like roast beef. While at least four hours is recommended for this recipe to fully infuse the meat with flavor, you can leave it for up to eight hours. After more than eight hours the beef will start to lose its structure. When marinating beef, you may be tempted to leave it as long as possible for the most tender results, but the meat will become unpleasantly mushy if marinated for too long. For this reason, avoid over-marinating.

Tip for Making Marinated Roast Beef Recipe

An eye-of-round roast is one of the best choices for this oven-roast beef, but it can be made with a sirloin tip roast or a rump roast.
