Nothing feels quite as comforting as a hearty rump roast with rich gravy—except when you can make it on a weeknight without babysitting the oven for hours. This Instant Pot rump roast recipe is the shortcut I reach for when I want that slow-cooked, fork-tender vibe in a fraction of the time.
Rump roast is leaner than chuck, so the key is building flavor (hello, browning) and cooking it just long enough with plenty of liquid so it turns tender—not dry. The Instant Pot makes that easier than ever, and the gravy? Let’s just say you’ll be spooning it over everything.
Why I love this recipe
- Comfort-food results, faster: It tastes like it cooked all day.
- One-pot magic: Meat, veggies, and gravy in one place.
- Great for leftovers: The next-day sandwiches are legendary.
Ingredients
For the roast
- 3 to 4 lb rump roast
- 2 tsp kosher salt
- 1 tsp black pepper
- 1 tsp garlic powder
- 1 tsp onion powder
- 2 tbsp oil (avocado or vegetable)
- 1 large onion, sliced
- 4 cloves garlic, minced
- 2 tbsp tomato paste (optional, adds depth)
Cooking liquid
- 2 cups beef broth
- 1 tbsp Worcestershire sauce
- 1 tbsp soy sauce (optional but great for umami)
- 1 tsp dried thyme (or 1 tbsp fresh)
- 1 tsp dried rosemary (crushed)
- 2 bay leaves
Vegetables (optional but recommended)
- 1 lb baby potatoes (or quartered Yukon golds)
- 4 large carrots, cut into big chunks
- 2 celery ribs, chopped (optional)
To thicken gravy
- 2 tbsp cornstarch
- 2 tbsp cold water
Swaps and notes
- No rump roast? Bottom round works similarly; chuck roast will be even more fall-apart.
- Broth options: Beef broth is best; chicken broth works in a pinch but is lighter.
- Flavor boost: A splash of balsamic vinegar (1–2 tsp) adds a subtle “roastiness.”
- Veg timing: If you like firmer veggies, cook them after the roast (I’ll show both ways).
Step-by-step instructions
1) Season and sear
Pat the roast dry. Season all over with salt, pepper, garlic powder, and onion powder.
Set Instant Pot to Sauté. Add oil. Sear the roast 3–4 minutes per side until deeply browned. Remove to a plate.
2) Sauté aromatics + deglaze
Add onion and cook 2–3 minutes. Stir in garlic (30 seconds). Add tomato paste if using and cook 30 seconds more.
Pour in beef broth and scrape up every browned bit from the bottom (this prevents burn warnings and makes the gravy amazing). Stir in Worcestershire, soy sauce (if using), thyme, rosemary, and bay leaves.
3) Pressure cook
Return roast to the pot.
Cook time guideline:
- For sliceable tender: 18 minutes per pound
- For shreddable tender: 20 minutes per pound
For a 3.5 lb roast, that’s 63–70 minutes on High Pressure.
4) Natural release
When done, let it naturally release 15 minutes, then quick release the rest.
5A) If cooking veggies with the roast (easy method)
Add potatoes and carrots around the roast before pressure cooking. They’ll be very tender at the end—classic pot-roast style.
5B) If cooking veggies after the roast (best texture)
Remove the roast, tent with foil. Add potatoes and carrots to the pot. Pressure cook 5 minutes, then quick release.
6) Make gravy
Remove bay leaves. Turn on Sauté.
Mix cornstarch + cold water. Stir into the pot and simmer 2–3 minutes until thickened. Taste and adjust salt/pepper.
7) Slice or shred
For slices: cut against the grain.
For shredding: pull apart and toss with a little gravy.
Tips for success
- Don’t skip the sear. It’s the difference between “good” and “whoa.”
- Cut against the grain to keep rump roast tender.
- Natural release matters. It keeps the meat juicy.
- If it’s not tender enough: Put it back for 8–12 more minutes on High Pressure, then natural release again.
Serving suggestions and pairings
- Serve with mashed potatoes, egg noodles, or crusty bread for gravy-dunking.
- Add a simple green veg (green beans, broccoli, or a crisp side salad) to balance the richness.
