Pot roast flavors in a bowl! This easy paleo and whole 30 recipe turns a family dinner favorite (pot roast) into a comforting soup. Make this in your slow cooker or Instant Pot.
Updated 2019 with Instant Pot instructions
Pot roast and soup. Two of the ultimate comfort foods. With winter being full-blown right now, I thought it would be only fitting that I convert one of my favorite pot roast recipes into a soup. Even though it’s 70 degrees here in Los Angeles.
This uses the traditional pot roast ingredients – beef, carrots, onions, potatoes (I used white sweet potatoes), low-sodium beef broth and some simple seasonings.
I used an arrowroot starch ‘slurry’ to thicken this soup up. Optional but recommended step. If you’re not worried about whole30/paleo then you can use the cornstarch or your preferred thickener.
I used white sweet potatoes because I wanted this to be paleo but you can use regular potatoes if you want. Don’t have thyme? Use rosemary or another herb.Print

- Add onion, carrots, and garlic and cook for a 2-3 minutes, stirring frequently. Add the broth, and using a wooden spoon scrape well the bottom of the IP to remove any bits that stuck to it, make sure you scrape it well to avoid burning during cooking. Add the beef back to the pot along with all remaining ingredients EXCEPT the arrowroot slurry.
- Close lid and seal valve. Set high pressure and cook for 9 minutes. Natural release pressure for 5 minutes then manually the remaining pressure.
Optional slurry to thicken- In a small bowl, mix together arrowroot slurry. Pour slurry into the IP and stir to mix well. Turn IP to WARM setting until soup has thickened to your liking.
If you don’t have beef stew meat then you can take a roast and cut it into chunks. You can even keep a small roast whole and shred the meat after it’s done cooking.
