Ingredients

3 to 4 lb rump roast, tied
2 tablespoon olive oil
2 teaspoon salt
1 teaspoon black pepper
1 large onion, sliced
3 cloves garlic, minced
4 large carrots, peeled & cut into 2-inch pieces
2 lbs baby potatoes, halved
2 cups beef broth
1 tablespoon Worcestershire sauce
2 teaspoon dried rosemary
2 teaspoon dried thyme
1 bay leaf
2 tablespoon cornstarch + 2 tablespoon water (for optional gravy)

Directions

Step 1: Sear the Roast

Pat the rump roast dry and season all sides with salt and pepper. Heat olive oil in a large skillet over medium-high heat. Sear the roast on all sides until browned, about 3-4 minutes per side. (This step is optional but adds delicious flavor!)

Step 2: Prep Your Slow Cooker

Add sliced onions, garlic, carrots, and potatoes to the bottom of your slow cooker.

Step 3: Add the Roast and Liquids

Place the seared roast on top of the veggies. Pour in beef broth and Worcestershire sauce. Sprinkle rosemary, thyme, and toss in the bay leaf.

Step 4: Slow Cook to Tender Perfection

Cover and cook on LOW for 8-9 hours or HIGH for 4-5 hours, until the roast is fork-tender and the vegetables are soft.

Step 5: Thicken the Gravy (Optional)

For a luxurious gravy, remove the roast and veggies to a platter. Whisk together 2 tablespoon cornstarch and 2 tablespoon cold water and stir into the liquid left in the slow cooker. Cover and cook on HIGH for 10-15 minutes, until thickened. Return roast and veggies, or serve gravy on the side.

Notes

Searing adds incredible depth of flavor, but skip if you’re in a hurry.
Cut hearty vegetables into large chunks so they don’t get mushy after long cooking.
Tie your roast with butcher’s twine to help it maintain shape through slow cooking.

Variations

Italian Style: Add a can of diced tomatoes and a teaspoon of Italian seasoning.
Spicy Kick: Sprinkle in crushed red pepper and add sliced jalapeños.
Mushroom Gravy: Stir in 8 oz sliced mushrooms for an earthy twist.

Storage Instructions

Let leftovers cool completely, then transfer to airtight containers. Store in the refrigerator for up to 4 days. To freeze, slice beef and place in freezer-safe containers with some cooking juices; freeze for up to 2 months. Reheat gently in the microwave or on the stovetop, adding a splash of broth to keep everything moist.

Suggested Pairings & Serving Recommendations

Serve with crusty bread or creamy mashed potatoes for a classic combo.
Pair with a crisp green salad or roasted green beans for freshness.
Top with fresh parsley or chives for color and flavor boost.

Pro Tips for Best Results

Allow your roast to rest for 10-15 minutes before slicing to lock in juices!
Always slice beef against the grain for maximum tenderness.
If you notice the veggies cooking too quickly, cut them into larger pieces or add halfway through.

FAQ

Can I skip searing the roast?

Yes, but searing adds extra flavor and a beautiful crust to your rump roast.

What’s the best way to thicken the gravy?

A cornstarch slurry (cornstarch plus water) thickens the sauce easily right in the slow cooker.

Can I prepare this ahead of time?

Absolutely! You can prep all ingredients the night before and refrigerate everything in the insert; just pop it in the slow cooker the next morning.
