Prime Rib Soup Recipe Pioneer Woman: Rich Beefy Broth With Tender Morsels

This soup transforms leftover prime rib into a tender, deeply flavorful meal that’s as comforting as it is impressive.

Using a slow simmer, the beef releases its rich essence into the broth, creating a base that’s both hearty and refined. Every spoonful delivers melt-in-your-mouth pieces of meat in a savory, aromatic liquid.

Ingredients for Prime Rib Soup Recipe Pioneer Woman

Leftover prime rib gets a second life in this rich, slow-simmered soup.

The prime rib is the star here, so use what you’ve got leftover—1.5 lbs is plenty for four. If you’re starting from scratch, ask your butcher for a well-marbled cut. Whole Foods or Costco have great options. The beef stock matters too; Better Than Bouillon base is my go-to for depth without the salt overload. Don’t skip the tomato paste—it’s the secret to that deep, savory backbone.

No leftover prime rib? Chuck roast works just as well—slow-cook it first, then cube. Swap beef stock for mushroom broth if you want a vegetarian twist (skip the Worcestershire). Fresh herbs can replace dried at one-third the amount, but dried hold up better in long simmers. If your stock is salty, taste before adding the Worcestershire—it’s potent stuff.

This soup actually gets better overnight as the flavors meld. Keeps for 4-5 days in the fridge, or freeze for 3 months. Reheat gently to keep the beef tender—no boiling, or it’ll toughen up.

Step-by-Step Instructions for Prime Rib Soup

Here’s the method. Straightforward, tested, works every time.

Step 1: Sauté the Aromatics and Thicken the Broth

Melt the 2 tbsp Butter in a large pot or Dutch oven over medium heat. Add the diced yellow onion, sliced carrots, and diced celery stalks. Cook for 5-7 minutes until the vegetables start to soften and the onion becomes translucent.

Stir in the 2 tbsp All-Purpose Flour to create a roux. Cook for 1-2 minutes, stirring constantly, until the mixture turns a light golden color. This step builds the base flavor and ensures a silky, thickened broth.

Step 2: Build Flavor with Garlic and Seasonings

Add the minced 4 cloves garlic cloves and cook for 30 seconds until fragrant. Stir in the 2 tbsp Tomato Paste and cook for another 1 minute to deepen its umami richness.

Pour in the 8 cups Beef Stock, then add the 1 tsp Dried Thyme, 1 tsp Dried Rosemary, 2 whole Bay Leaves, 1 tbsp Worcestershire Sauce, 1 tsp Kosher Salt, and 0.5 tsp Black Pepper. Bring to a boil, then reduce the heat to medium-low and let it simmer for 10 minutes.

Step 3: Add the Leftover Prime Rib and Finish Cooking

Gently stir in the cubed 1.5 lb Leftover Prime Rib. Simmer for another 10-15 minutes until the vegetables are tender and the flavors meld beautifully. The prime rib will warm through and infuse the broth with its rich, beefy essence.

Taste and adjust the seasoning if needed, but remember the beef stock and leftover prime rib already bring a lot of flavor to the table. Remove the 2 whole Bay Leaves before serving.

Step 4: Serve Hot and Enjoy

Ladle the soup into bowls while it’s still hot. The broth should be rich and velvety, packed with tender chunks of prime rib and perfectly cooked vegetables. Each spoonful delivers layers of savory depth from the herbs, tomato paste, and beef stock.

This soup is hearty and satisfying on its own, but it pairs wonderfully with crusty bread or a simple green salad. The flavors will continue to develop if you let it sit for a few minutes, so don’t rush—savor every bite.

Troubleshooting This Dish

Broth Too Thin

If your soup lacks body, mix 1 tbsp cornstarch with 2 tbsp cold water and stir into the simmering broth. Cook for 2-3 minutes until thickened. I prefer this over flour for a clearer finish. 💡

Meat Turns Tough

Prime rib can overcook quickly in broth. Add it only during the final 10-15 minutes of simmering. If using pre-cooked meat, just warm it through—boiling makes it chewy.

Flavor Falls Flat

Boost depth with 1 tsp fish sauce or 1 tbsp soy sauce—both add umami without overpowering. A splash of red wine (about ¼ cup) while sautéing aromatics also works wonders.

Greasy Surface

Skimming fat is key. Chill the soup for 20 minutes, then lift off solidified fat with a spoon. For immediate results, drag a paper towel across the surface to absorb excess grease.

Vegetables Mushy

Cut carrots and celery into 1-inch pieces for even cooking. Add them with the aromatics, not the meat, to prevent over-softening. Crisp-tender is the goal here.

Herbs Overpower

Dried rosemary and thyme can dominate. Use ½ tsp each if sensitive to strong flavors, or tie herbs in cheesecloth for easy removal. Fresh herbs are milder but less durable in long simmers.
