The Ingredients

This recipe uses simple, affordable ingredients that come together beautifully.

3 to 4 pounds boneless beef roast (chuck roast or rump roast) – Chuck roast is more marbled and flavorful; rump roast is leaner.
1 (1-ounce) packet dry au jus gravy mix – The secret to the rich, savory flavor.
2 cups low-sodium beef broth – For the au jus. Low-sodium lets you control the salt.

Step-by-Step Instructions

Step 1: Preheat and Prep

Preheat your oven to 300°F (150°C). Choose a deep baking dish or casserole dish that will comfortably hold the roast with room around it for the au jus. A dish with higher sides is best so the beef can sit in the gravy as it cooks.

Pro Tip: A deep dish with higher sides keeps the roast partially submerged in the au jus, which keeps it moist and flavorful.

Step 2: Pat the Roast Dry

Pat the beef roast dry with paper towels. This helps it brown a little better and keeps the juices from watering down the flavor. Place the roast in the center of the baking dish.

Pro Tip: Dry beef = better browning and more concentrated flavor.

Step 3: Season the Roast

Sprinkle the dry au jus gravy mix evenly over the top and sides of the roast. Use your hands to gently press the seasoning onto the meat so it sticks. You want the roast well coated, like my grandmother always said, “Give it a good jacket.”

Pro Tip: Press the seasoning firmly into the meat so it adheres and flavors every bite.

Step 4: Add the Broth

Slowly pour the beef broth around the roast into the baking dish, being careful not to wash all the seasoning off the top. The broth should come about ⅓ to ½ of the way up the sides of the roast. This liquid will turn into the rich brown au jus as it cooks.

Pro Tip: Pour the broth around, not over, the roast to keep the seasoning in place.

Step 5: Cover and Bake

Cover the baking dish tightly with heavy-duty aluminum foil or a fitted lid. A tight seal is important to keep the moisture in so the roast turns out tender instead of dry. Place the covered dish in the preheated oven and bake for 3 to 3½ hours, or until the beef is very tender and easily pulls apart with a fork. Thicker roasts may need a little more time. Try not to peek too often so you don’t let the steam escape.

Pro Tip: Don’t lift the foil! Every time you open the oven, you lose heat and moisture.

Step 6: Rest the Roast

Carefully remove the dish from the oven and peel back the foil away from you to avoid the hot steam. Transfer the roast to a cutting board and let it rest for about 10 minutes so the juices settle and the slices hold together.

Pro Tip: Resting is essential—it allows the juices to redistribute and the meat to firm up for slicing.

Step 7: Skim and Taste the Au Jus

While the roast rests, skim any excess fat from the surface of the au jus in the baking dish with a spoon. Taste the au jus and adjust with a pinch of salt if needed, keeping in mind that the au jus packet already has seasoning.

Pro Tip: Skimming the fat gives you a cleaner, richer au jus.

Step 8: Slice and Serve

Slice the roast across the grain into thin slices. Return the slices to the baking dish, nestling them into the warm au jus so they’re mostly submerged. This is what gives you that look of tender slices swimming in rich brown gravy. Spoon some of the hot au jus over the top of the beef, then serve the roast right from the deep white casserole dish at the table.

Pro Tip: Slicing across the grain ensures the meat is tender and easy to chew.
