Step-by-Step Instructions

Step 1: Preheat the Oven

Preheat your oven to 325°F (165°C).

Step 2: Season the Beef

Pat the roast dry with paper towels. Rub it with olive oil, then season all sides with salt, pepper, garlic powder, onion powder, and smoked paprika.

Step 3: Sear the Roast

Heat a large skillet over medium-high heat. Sear the roast for 3–4 minutes on each side until deeply browned.

Step 4: Prepare the Casserole Dish

Arrange the sliced onions, garlic, carrots, potatoes, and celery (if using) in the bottom of a large casserole dish.

Step 5: Place the Roast

Set the browned roast on top of the vegetables.

Step 6: Make the Au Jus

In a bowl, whisk together the beef broth, beef stock, Worcestershire sauce, soy sauce, tomato paste, thyme, rosemary, and bay leaves.

Step 7: Pour Over the Roast

Carefully pour the au jus mixture around the roast, leaving the top exposed.

Step 8: Cover

Cover the casserole dish tightly with a lid or aluminum foil.

Step 9: Roast

Bake for 3½–4 hours, or until the beef is fork-tender.

Step 10: Baste

About halfway through cooking, spoon some of the cooking juices over the roast.

Step 11: Rest

Transfer the roast to a cutting board and let it rest for 15 minutes before slicing.

Step 12: Finish the Au Jus

Remove the bay leaves and skim any excess fat from the cooking liquid if desired.

Step 13: Slice

Slice the roast against the grain into thick, juicy slices.

Step 14: Serve

Return the sliced beef to the casserole dish or serve on a platter with the rich brown au jus spooned over the top.

Step 15: Garnish

Sprinkle with fresh parsley and cracked black pepper before serving.

Tips, Notes & Q&A

Tips

• Chuck roast provides the most tender results after slow cooking.
• Searing the beef first creates a richer flavor and deeper color.
• Keep the casserole tightly covered to retain moisture.
• Leftover au jus is excellent for dipping sandwiches.
• For a thicker gravy, whisk 1 tablespoon cornstarch with 2 tablespoons cold water and stir it into the hot cooking liquid.

Can I prepare this ahead of time?
Yes. Cook the roast a day ahead, refrigerate overnight, and gently reheat in the au jus before serving.

How should I store leftovers?
Store the beef and au jus together in an airtight container in the refrigerator for up to 4 days.

Can I freeze it?
Yes. Freeze sliced beef with the au jus for up to 3 months. Thaw overnight in the refrigerator before reheating.

What should I serve with it?
Mashed potatoes, buttered noodles, roasted vegetables, rice, dinner rolls, or a crisp green salad pair perfectly with this roast.
