Jump to RecipeIngredients Needed
- 4 beef ribs (from a cooked prime rib roast): leftover goodness.
- 2 cups beef stock: builds on the broth.
- 1 medium potato, peeled + cubed: ¾-inch-ish. not fussy.
- 8 oz fresh sliced mushrooms (1 pack): earthy and soft.
- 1 tsp salt: you’ll adjust later.
- 1 tsp black pepper: enough to warm things up.
- ¼ cup fresh chives, chopped: for garnish. green = good.
How To Make Pioneer Woman Prime Rib Soup
Boil the Bones:
Drop those ribs in a pot. Cover with water. Bring it to a boil then drop to a simmer. Lid on. Walk away for like 2 hours. Smells amazing. You’ll know it’s ready when the meat basically falls off.
Pick the Meat:
Take the ribs out and let them cool. Pick the meat off the bones (don’t rush this). Cut into bite-sized pieces. Stick it in the fridge. Eat a bite if you want. I always do.
Reduce the Broth:
Keep simmering what’s left in the pot. Let it go ‘til it’s down to about 1 cup. That’s your flavor bomb. Toss it in the fridge too, just until the fat solidifies.
Skim the Fat:
Once chilled, scoop the fat off the top. Discard it (or save it, no judgement). You want that deep, beefy broth underneath.
Make the Soup:
Pour that reduced broth into a saucepan. Add the chopped meat, beef stock, potatoes, mushrooms, salt, and pepper. Bring it to a boil. Then simmer for 20 mins or so. Potatoes should be fork soft.
Finish It:
Sprinkle chopped chives on top before serving. Eat hot. maybe with bread. definitely with a spoon.

Recipe Tips
- Let the bones simmer long enough — flavor needs time.
- Cut potatoes evenly or they’ll cook uneven.
- Chill that broth. skimming fat is way easier cold.
- Salt at the end — stock is salty already.
- Leftovers taste even better next day. that’s just facts.
How to Store Leftovers
Fridge: Airtight container. Up to 3 days.
Freezer: Freeze in portions. Lasts 2 months.

FAQs
Can I use uncooked prime rib bones?
Nope. This one’s for leftover cooked ribs. That roasted flavor is key.
What if I don’t have mushrooms?
Skip them. Or use carrots. Or celery. Soup is forgiving.
Can I add noodles or rice?
You could. But it’s already hearty. Just don’t overdo it.
How do I know when the potatoes are done?
Poke one with a fork. If it breaks apart easy — you’re good.
Can I make this in a slow cooker?
Yes — simmer the bones and broth low for 4–6 hours. Then finish the rest stovetop.
