A rump roast cooks in low-sodium broth with onion soup mix and a little Worcestershire, then the drippings thicken into a brown gravy. It is pulled at 190 to 195°F.

Ingredients

  • 3 lb beef rump roast, trimmed

  • 1 packet (about 1 oz) dry onion soup mix

  • 2 cups low-sodium beef broth

  • 1 tbsp Worcestershire sauce

  • 1 large yellow onion, sliced into half-moons

  • 3 garlic cloves, minced

  • 1 tsp dried thyme

  • 1/2 tsp black pepper

  • 8 oz cremini mushrooms, halved

  • 3 tbsp butter

  • 3 tbsp all-purpose flour

  • Mashed potatoes or egg noodles, to serve

Directions

  • Pat the roast dry and rub the onion soup mix over all sides, pressing it in so it sticks.
  • Layer the sliced onion, garlic and mushrooms in the bottom of a 6-quart slow cooker.
  • Set the roast on top and pour the broth and Worcestershire around it, not over it, so the rub stays on the meat.
  • Sprinkle the thyme and pepper over the top. The liquid should come about three quarters of the way up the roast.
  • Cover and cook on LOW for 7 to 8 hours. Do not use HIGH if you will be out when it finishes.
  • Halfway through, flip the roast once and close the lid at once.
  • From hour 6, check the thickest part with a probe thermometer. Pull the roast at 190 to 195°F when a fork twists it apart.
  • Rest the roast 10 to 15 minutes on a platter. Ladle 3 cups of the hot cooking liquid into a measuring jug.
  • Melt the butter in a saucepan over medium heat, whisk in the flour and cook 1 minute. Pour in the hot liquid a little at a time, whisking, and simmer until smooth and thick.
  • Taste the gravy before adding salt, then slice or shred the roast and serve it over mashed potatoes or egg noodles.

Notes

    The soup mix is already salty, so use low-sodium broth and add no salt until the gravy is tasted. If you over-thicken the gravy, whisk in a splash of beef broth. Leftover meat keeps 3 to 4 days in the gravy, which protects it from drying out when you reheat it. Reheat to 165°F over low heat, covered.

Why rump needs gravy

Rump is lean, so gravy protects it. The soup mix seasons the meat and the drippings make a quick butter and flour sauce.

The mushrooms add body.

Swaps and serving

Gluten-free flour can replace regular flour in the gravy. Do not add salt early. Serve over mashed potatoes or noodles.

Green beans round it out.

Storing and the HIGH mistake

Leftovers keep 3 to 4 days in the gravy.

The mistake is using HIGH when you are away. Lean rump goes from tender to dry quickly without someone checking.

Finishing the gravy

Whisk the hot liquid into the butter and flour a little at a time so the gravy stays smooth. If it looks too thick, add broth. Taste before salting, since the soup mix does a lot of work. The mushrooms in the pot add body without extra effort.

Serve the gravy poured over the meat and potatoes while hot. If any is left over, it keeps with the meat and reheats gently without drying it out.

Hi, I'm Iren Pavlenko. I read the top-ranked slow cooker recipes for a dish side by side and write down what they disagree on and what they all leave out — the cut, the pot size, and both the LOW and HIGH times. I write these guides so your weeknight dinner doesn't turn into a dry roast because a recipe never said which of those four things mattered.
