Ingredients

3 pounds beef chuck roast or bottom round roast
1 packet (1 ounce) au jus gravy mix
1/2 cup unsalted butter, cut into pieces

Water or beef broth is considered a free pantry staple. You will need about 2 cups. Salt and black pepper can be added to taste.

Directions

Preheat your oven to 325°F (165°C).
Pat the roast dry with paper towels and season all over with salt and pepper.
Place the roast in a Dutch oven or roasting pan.
In a medium bowl, whisk together the au jus gravy mix and 2 cups of water or beef broth.
Pour the mixture around the roast, then scatter the butter pieces over the top.
Cover tightly with a lid or aluminum foil and bake for 3 to 3½ hours, until the beef is very tender and shreds easily with a fork.
Remove the roast from the oven and let it rest for 10 to 15 minutes before slicing or shredding.
Serve with the au jus spooned over the top.

Variations

Slow Cooker Version: Transfer everything to a slow cooker and cook on LOW for 8 to 10 hours.
French Dip Sandwiches: Shred the beef, pile it onto crusty rolls, and serve with the au jus for dipping.
Herb Infusion: Add 1 teaspoon of dried thyme or rosemary to the au jus mixture.
Red Wine Version: Replace ½ cup of the water with dry red wine for a deeper flavor.
Vegetable Boost: Add carrots, potatoes, and onions around the roast before baking.
Spicy Kick: Add a pinch of red pepper flakes or a dash of hot sauce to the au jus.

Expert Tips

Use chuck roast for the most tender results. Its marbling breaks down beautifully during long cooking.
Sear the roast first. For extra depth of flavor, sear it in a hot skillet before baking. This step is optional but recommended.
Keep it covered. The tight lid traps steam and ensures the beef stays moist and tender.
Let it rest. Resting allows the juices to redistribute, keeping the meat juicy.
Skim the fat. If the au jus is greasy, skim off excess fat before serving.

Storage and Reheating

Store leftovers in an airtight container in the refrigerator for up to 4 days. Reheat gently on the stovetop or in the microwave with a splash of broth to loosen the au jus. This dish freezes well for up to 3 months. Thaw overnight in the refrigerator before reheating.
