Ingredients

• 3 to 4 pounds beef chuck roast
• 1 packet (about 1 ounce) dry au jus gravy mix
• 2 cups beef broth

The three ingredients are: beef roast, au jus gravy mix, and beef broth.

How to Make 3-Ingredient Au Jus Roast Beef

1. Prepare the Oven

Preheat your oven to 325°F (165°C).

Place the chuck roast in a Dutch oven or deep baking dish with a tight-fitting lid.

2. Season the Beef

Sprinkle the dry au jus seasoning evenly over the top and sides of the roast.

Au jus seasoning can already contain plenty of sodium, so additional salt usually isn’t necessary.

3. Add the Beef Broth

Pour the beef broth around the roast rather than directly over the top. This helps keep the seasoning on the meat while providing plenty of moisture for braising.

4. Cover and Slow Bake

Cover the Dutch oven with its lid. If using a baking dish, cover it tightly with heavy-duty aluminum foil.

Bake for approximately 3–4 hours, depending on the size and thickness of the roast.

For a chuck roast, you’re looking for fork-tender meat, not merely the minimum safe temperature. The roast is ready when a fork slides easily into the meat and it can be pulled apart with little resistance.

5. Rest the Roast

Carefully transfer the cooked beef to a cutting board or serving platter.

Let it rest for approximately 10–15 minutes before slicing or pulling it into large pieces.

6. Prepare the Au Jus

Stir the cooking liquid remaining in the baking dish.

If you prefer a more concentrated au jus, transfer the liquid to a saucepan and simmer it for several minutes until slightly reduced.

Taste before adding additional seasoning because the au jus mix and beef broth can both contain salt.

7. Slice and Serve

Slice the beef against the grain for tender pieces, or gently pull it apart with two forks for a more rustic presentation.

Spoon the warm au jus generously over the beef before serving.

Tips for Tender Oven-Baked Roast Beef

Chuck roast is ideal for this recipe because its connective tissue softens during long, moist cooking, creating tender beef.

Keep the baking dish tightly covered. The trapped moisture is important for braising the roast and preventing the cooking liquid from evaporating too quickly.

Don’t panic if the roast still feels tough after a couple of hours. Chuck roast often needs additional cooking time before its connective tissue breaks down enough to become fork-tender.

For richer flavor, you can brown the roast in a hot skillet before baking, although that would require an additional ingredient such as oil.

Easy Variations

If you don’t need to keep the recipe strictly three ingredients, add sliced onions, mushrooms, garlic, or pepperoncini peppers around the roast before baking.

For an extra-rich gravy-style sauce, thicken some of the finished au jus with a cornstarch slurry.

You can also add carrots and potatoes to turn the roast into a complete one-pan dinner.

What to Serve With Au Jus Roast Beef

This tender roast is especially delicious with creamy mashed potatoes, which soak up the savory au jus beautifully.

Other good choices include roasted potatoes, buttered egg noodles, green beans, roasted carrots, broccoli, dinner rolls, or a simple green salad.

Leftover beef also makes excellent hot roast beef sandwiches.

How to Store Leftovers

Store leftover roast beef together with some of the au jus in an airtight container in the refrigerator for up to 3–4 days.

Keeping the meat with its cooking liquid helps prevent it from drying out.

Reheat gently in a covered skillet or saucepan with some of the au jus until thoroughly heated.

Cooked roast beef can also be frozen for up to 3 months.

Frequently Asked Questions

What cut of beef works best?

Chuck roast is an excellent choice when you want tender, pull-apart beef. Its marbling and connective tissue are well suited to long oven braising.

Can I use rump roast?

Yes, but rump roast is leaner and behaves differently from chuck. If your goal is very tender, easily pulled beef, chuck is generally the easier choice.

Do I need to add water?

No. Beef broth provides the cooking liquid while also adding more flavor than plain water.

Why is my roast still tough?

If you’re using chuck roast and it remains tough, it usually needs additional braising time. Continue cooking it covered and check again later.

Can I make this ahead?

Yes. Roast beef reheats particularly well when stored in its au jus. You can cook it a day ahead, refrigerate it, and gently reheat it before serving.

Final Thoughts

This Oven Baked 3-Ingredient Au Jus Roast Beef proves that a hearty family dinner can be incredibly simple. Beef chuck roast, au jus seasoning, and beef broth slowly bake together until the meat is tender and surrounded by deeply savory cooking juices.

Serve it with mashed potatoes and vegetables for a classic comfort-food dinner, or use the leftovers for easy roast beef sandwiches the next day.
