If you like seeing some "red" in your meat, this recipe is for you! Since the goal is to sear the natural juices inside the roast, you'll get very little in the pan. Gravy lovers might want a can of beef broth or packaged mix. You'll love the aroma as it cooks and how the caramelized onion flavors the juice!

Ingredients Nutrition


  1. Pre-heat oven to very hot, 500 degrees F.
  2. Prepare 8x8 baking pan with non-stick spray.
  3. Remove excess fat from roast, pat dry with paper towel, and place in pan.
  4. Rub pepper on the roast if desired.
  5. Liberally rub or brush with oil.
  6. Arrange onion slices to cover the bottom of the pan around the roast.
  7. (Note the "grain" of the roast before cooking since it will seem more tender if carved against, or perpendicular to, the grain rather than parallel with the grain.)
  8. Place in hot oven, uncovered--note that the times below are from this point.
  9. After 5-10 minutes lower oven setting to 350F; let the oven cool gradually without opening door After 35-40 minutes, pour about 1/2 cup hot water over the onions; make a foil tent to cover the brownest parts of the roast, spraying first with non-stick spray, and return to oven.
  10. Add 1/2 cup hot water at 15-20 minute intervals or whenever the bottom becomes dry and cook to desired level of doneness: Approx.
  11. 1 hr (20 mi. per lb.) for rare (125-130F); 1 1/4 hr (25mi. per lb.) medium rare (135-140F); 1 1/2 hr (30 mi. per lb.) medium (145-150F); 1 3/4 hr (35 mi. per lb.) medium well (155-160F).
  12. Important: Allow the roast to"rest" at room temperature for at least 15 minutes before carving
  13. Transfer roast to serving platter, and pour another 1/2 cup of hot water over the drippings (assuming they're fairly dry), stir, strain out the onions, and pour over the roast.

Man, what a rump roast!! I made this last night for my family and it was EXCELLENT. I substituted beef broth for the water, heating it up with some onions, and it was fabulous. I rubbed the meat with seasoning salt, black pepper and garlic powder after oiling it.

This was absolutely fantastic -- juicy, perfect roast. I roasted it 10 minutes at 500 degrees, then only about 40 minutes more at 350 for a slightly less than 3 lb roast. I appreciate the suggestion to use a thermometer! I couldn't believe this cut came out so tender in so little time. I was afraid when searching for recipes that I'd have to settle for "pot roast" but really wanted it rarer for au jus sandwiches. Thanks so much!!!
