No reviews

A foolproof, hands-off slow cooker pot roast with a rich, savory-sweet glaze from ranch seasoning, au jus, and cream of mushroom soup, finished with golden onion rings.

  • Total Time: 8 hours 15 minutes
  • Yield: 6 servings

Ingredients

Scale
  • 34 lb beef chuck roast
  • 1 packet ranch seasoning mix
  • 1 packet brown gravy mix
  • 1 cup au jus or beef broth
  • 1 can (10.5 oz) condensed cream of mushroom soup
  • 45 medium baby carrots
  • 45 small Yukon Gold potatoes, unpeeled and halved
  • 1 large yellow onion, sliced into rings
  • 2 tbsp olive oil
  • Fresh parsley, chopped (optional garnish)

Instructions

  1. Pat the beef roast dry and season lightly with salt and pepper.
  2. Place half the onion rings in the bottom of a 6-qt slow cooker.
  3. Set the roast on top of the onions and sprinkle with ranch seasoning and gravy mix.
  4. Pour in the au jus and cream of mushroom soup around the roast.
  5. Cover and cook on LOW for 8 hours or HIGH for 5–6 hours, until fork-tender.
  6. During the last 30 minutes, add carrots and potatoes around the roast (if using firm vegetables) or at the end if using softer ones.
  7. Top with remaining onion rings in the final 15 minutes to caramelize slightly.
  8. Shred or slice the roast, spoon pan juices over top, and garnish with parsley before serving.

Notes

  • For extra crispy onions, broil the final onion topping for 2–3 minutes after cooking.
  • Double the sauce for mashing into potatoes or serving over egg noodles.
  • Frozen carrots and potatoes work well—just added 30 minutes before end of cook time.
  • Leftovers freeze well and are great in sandwiches or over rice.
