Ingredients
For the Roast
- 3 to 4 pounds boneless beef roast (chuck roast or rump roast)
- 1 packet (1 ounce) dry au jus gravy mix
- 2 cups low-sodium beef broth
Instructions
Step 1: Prepare the Oven
Preheat your oven to 300°F (150°C). Select a deep baking dish or casserole dish large enough to hold the roast comfortably with space around the sides for the cooking liquid.
Step 2: Prepare the Roast
Pat the beef roast dry using paper towels. Removing excess moisture helps the seasoning adhere better and allows the meat to develop deeper flavor during cooking.
Place the roast in the center of the baking dish.
Step 3: Season the Meat
Sprinkle the dry au jus gravy mix evenly over the top and sides of the roast. Gently press the seasoning into the meat to help it stick and create a flavorful coating.
Step 4: Add the Broth
Slowly pour the beef broth around the roast rather than directly on top. This helps preserve the seasoning layer while providing enough liquid to keep the roast moist during the long cooking process.
The broth should reach about one-third to halfway up the sides of the roast.
Step 5: Cover and Bake
Cover the baking dish tightly with aluminum foil or a fitted lid. A secure seal traps steam inside, ensuring the beef becomes tender and juicy.
Place the dish in the oven and bake for 3 to 3½ hours, or until the beef is fork-tender and easily pulls apart.
Larger or thicker roasts may require additional cooking time.
Step 6: Rest the Roast
Carefully remove the dish from the oven and uncover it, allowing the steam to escape away from you.
Transfer the roast to a cutting board and let it rest for 10 minutes before slicing. Resting allows the juices to redistribute throughout the meat.
Step 7: Prepare the Au Jus
While the roast rests, skim any excess fat from the surface of the cooking liquid.
Taste the au jus and adjust the seasoning if needed. Keep in mind that the gravy mix already contains salt and seasonings.
Step 8: Slice and Serve
Slice the roast against the grain into thin slices for maximum tenderness.
Return the slices to the baking dish and spoon the warm au jus over the top. Allow the meat to sit in the gravy for a few minutes before serving so it can absorb even more flavor.
Serve directly from the casserole dish with plenty of extra au jus on the side.
Serving Suggestions
This roast beef pairs beautifully with a variety of classic side dishes:
- Creamy mashed potatoes

The flavorful au jus is perfect for spooning over potatoes, rice, or vegetables.
Recipe Variations
Make It Kid-Friendly
For younger eaters, shred the beef instead of slicing it. The tender shredded meat is delicious served over mashed potatoes or tucked into soft sandwich rolls.
Create a Thicker Gravy
If you prefer a gravy-like consistency, transfer the au jus to a saucepan and bring it to a gentle simmer.
Mix:
- 1 tablespoon cornstarch
- 2 tablespoons cold water
Whisk the mixture into the simmering au jus and cook until slightly thickened.
Add Extra Flavor
For a deeper roasted flavor, sear the beef in a hot skillet before placing it in the baking dish. This optional step creates a rich caramelized exterior and adds complexity to the finished dish.
Storage and Leftovers
Store leftover roast beef and au jus in an airtight container in the refrigerator for up to 4 days.
To reheat, place the beef in a saucepan with some of the au jus and warm gently over low heat until heated through.
The leftovers also make excellent sandwiches, sliders, wraps, and beef bowls.
Helpful Tips
- Use chuck roast for maximum tenderness.
- Avoid opening the oven frequently during cooking.
- Slice the beef against the grain for the most tender texture.
- Allow the roast to rest before slicing.
- Keep leftover beef stored in its au jus to maintain moisture.
