Learned this from my grandmother and it never disappoints

This Oven Baked 3-Ingredient Au Jus Roast Beef is a magnificent, slow-braised carving masterpiece that flips a standard cut of beef into an elite, melt-in-your-mouth comfort luxury. By blanketing a robust chuck or rump roast in a savory canopy of dry au jus seasoning and slow-simmering it in a deep pool of low-sodium beef broth, you construct a flawless structural flavor matrix. Tightly sealed and baked under low, steady oven heat, the dense meat fibers completely break down, infusing the broth with rich, natural beef gelatin to create a premium, full-bodied dipping gravy. It stands as an exceptionally high-reward dinner centerpiece that delivers restaurant-quality carvery elegance with absolute minimal kitchen monitoring.

Oven Baked 3-Ingredient Au Jus Roast Beef

Ingredients:

Step-by-Step Directions:

Step 1: Ignite the Steady Oven Heat: Preheat your oven to a low, gentle 300°F (150°C). Select a deep baking dish or high-sided casserole dish that can comfortably nestle the meat block with plenty of extra volumetric space around the borders to contain the simmering gravy pools.

Step 2: Apply the Seasoning Jacket: Pat the entire surface of your 3 to 4 lb beef roast completely bone-dry with paper towels to clear away surface moisture. Place the roast flat in the center of your deep dish. Sprinkle the 1 / packet of dry au jus gravy mix completely uniformly over the top and sides of the meat canopy, using your hands to gently press the savory crystals firmly into the muscle walls so it holds a thick, even seasoning jacket.

Step 3: Introduce the Braising Liquid: Slowly pour your 2 cups of low-sodium beef broth into the empty floor space around the perimeter of the roast. Be exceptionally careful not to pour the liquid directly over the top of the beef, as you do not want to wash away your pressed seasoning jacket. The broth line should rise roughly 1/3 to 1/2 of the way up the vertical sidewalls of the meat.

Step 4: Lock the Steam Seal: Seal the baking dish exceptionally tightly with a sheet of heavy-duty aluminum foil or a precisely fitted lid.

Tip: This tight structural seal is non-negotiable! The low-and-slow cooking method relies entirely on trapped, high-pressure steam to dissolve the tough connective tissues inside the roast. A loose seal will allow your broth to evaporate, leaving you with a dry, leathery texture instead of fork-tender meat.

Step 5: Execute the Low and Slow Braise: Slide the sealed dish onto the center oven rack and bake undisturbed for 3 / to 3 1/2 / hours. Resist the urge to peek or crack the foil during the cycle. The roast is perfectly executed the exact moment the beef fibers lose their rigidity and pull apart effortlessly with the gentle press of a kitchen fork.

Step 6: The Rest and Skim Protocol: Carefully lift the pan from the oven and peel the foil back away from your face to safely redirect the hot steam currents. Lift the tender roast out of the liquid and transfer it to a clean cutting board, letting it stand undisturbed for exactly 10 / minutes so the internal juices can settle back into the meat walls. While it rests, use a wide spoon to skim away any heavy pool oils floating on the surface of the remaining au jus.

Step 7: Slice and Submerge: Using a sharp chef’s knife, carve the rested roast across the natural grain lines into thin, elegant slices. Transfer the carved meat straight back into the deep baking dish, nestling the slices uniformly into the warm au jus so they are beautifully submerged and glazed. Ladle extra hot gravy over the top and serve right from the dish!
