This slow cooker 5-ingredient au jus beef roast is the kind of weeknight dinner I lean on when I want something deeply savory with almost no effort. It borrows its flavor from classic French-style jus—those simple, concentrated pan drippings—but translates it into an easy, set-it-and-forget-it method. The key is a lean beef top round roast, a packet of au jus gravy mix, and just three pantry ingredients to create a rich, spoonable jus. You literally sprinkle, pour, cover, and walk away. By the time you’re ready to eat, the meat is tender enough to pull apart, and in my house it tends to vanish before I can even think about packing leftovers.
Serve the sliced or shredded beef with its jus over creamy mashed potatoes, buttered egg noodles, or a bed of steamed white rice to soak up all the savory juices. A simple green side—like roasted green beans, a crisp salad with vinaigrette, or sautéed broccoli—balances the richness nicely. For a more casual meal, pile the beef onto toasted hoagie rolls with a slice of provolone and offer the warm jus in small bowls for dipping, French dip–style. A light red wine or a cold lager pairs well with the beef’s deep, salty-savoriness.
Slow Cooker 5-Ingredient Au Jus Beef RoastServings: 6
Ingredients
1 (2 1/2 to 3 pound) beef top round roast, trimmed
1 (1-ounce) packet au jus gravy mix
1 cup low-sodium beef broth
1 medium yellow onion, sliced
2 tablespoons unsalted butter, cut into pieces
Directions
Place the sliced onion in an even layer on the bottom of a 5- to 6-quart slow cooker to create a bed for the roast and add sweetness to the jus.
Set the beef top round roast on top of the onions in the slow cooker, fat side up if there is a fat cap.
Sprinkle the dry au jus gravy mix evenly over the top and sides of the raw roast, letting any excess fall into the slow cooker around the meat.
Pour the beef broth around the roast (not directly over the top so you don’t wash off the seasoning), letting it settle into the bottom of the slow cooker.
Dot the top of the roast with the pieces of butter, spacing them out so they melt evenly over the meat as it cooks.
Cover the slow cooker with the lid and cook on LOW for 8 to 9 hours, or on HIGH for 4 to 5 hours, until the beef is very tender and can be easily pulled apart with a fork.
Transfer the roast to a cutting board. Let it rest for about 10 minutes, then slice it against the grain or gently shred it with two forks, depending on how you prefer to serve it.
Skim excess fat from the surface of the cooking liquid in the slow cooker, then stir the onions into the jus. Taste and adjust seasoning with a small pinch of salt if needed.
Return the sliced or shredded beef to the slow cooker, nestling it into the warm au jus, and let it sit on the WARM setting for 10 to 15 minutes so the meat can soak up more flavor before serving.
Variations & Tips
For a little heat, add 1 to 2 teaspoons of crushed red pepper flakes or a few dashes of hot sauce to the broth before cooking. If you prefer a stronger onion presence, use two onions instead of one, or swap in a sweet onion for a milder, caramel-like flavor. To tilt this toward a French dip sandwich, skip slicing the roast thinly, shred it instead, and serve on toasted baguette or hoagie rolls with provolone or Swiss, broiled just until the cheese melts, with small bowls of the warm jus for dipping. For a slightly richer jus, substitute 1/4 cup of the beef broth with dry red wine. If you like a thicker, gravy-like sauce, after removing the beef whisk 1 tablespoon cornstarch with 2 tablespoons cold water, stir it into the hot jus, and cook on HIGH for 15 minutes until lightly thickened. You can also adapt this for meal prep: cook the roast, shred it, cool it in its jus, and refrigerate up to 3 days; reheat gently in the slow cooker or on the stovetop, adding a splash of broth if needed to loosen the sauce.
