It’s an inevitable outcome that you will have leftovers when you make a big pot roast dinner.
But what should you do with them, if you don’t want to eat the same thing for a few days in a row?
Not sure? Drawing a blank?
Maybe that’s because the bird bests the beef when it comes to leftovers!
There’s no surprise that turkey is the main meat that gets alllllllll of the attention with leftover recipes, especially when Thanksgiving comes around. A quick search on the internet pulls up countless recipes for sandwiches, stir-fries, pastas, casseroles, and soups.
The options are all delicious, of course, including our own recipe for white bean turkey chili.
But I’m tired of the turkey talk!
Holiday poultry aside, what are you supposed to do with the meaty leftovers from the dinners you make during the rest of the year?
Rather than simply reheating a plate of the same thing you had last night, dive a little deeper into the well of culinary creativity by making something new, exciting, and tasty.
Leftover pot roast is a perfect place to start!
If you live in a household that loves a hearty pot roast for a weeknight dinner, I have the perfect recipe to breathe new life into anything you may need to use up.
This ultra-savory pot roast mushroom soup will have you salivating during every single step of the cooking process.
You’ll be sneaking as many sips and spoonfuls as you possibly can as it cooks.

Sure, pot roast leftovers are typical. But I’ll be surprised if you have any more leftovers after you make this irresistible recipe!Print
Not sure what to do with your leftover pot roast? Use the remaining meat to make our hearty and comforting soup with mushrooms in a rich broth.
- 2 tablespoons olive oil
- 1 small onion, diced (about 1 cup)
- 2 cloves garlic, minced
- 1 teaspoon chopped fresh thyme, plus more for garnish
- 8 ounces button mushrooms, stems removed and sliced
- 2 tablespoons balsamic vinegar
- 4 cups beef stock or beef broth, divided
- 2 tablespoons cornstarch
- 2 cups chopped or shredded cooked pot roast
- 1/2 teaspoon salt, plus more to taste
- 1/4 teaspoon black pepper, plus more to taste
- Heat the olive oil in a large pot over medium heat. Add the onion and saute for about 5 minutes, or until soft and translucent.
- Add the garlic and thyme and saute for an additional 30 seconds, stirring constantly.
- Add the mushrooms and continue to cook, stirring occasionally, until they are dark brown and have released their moisture, about 5 to 8 minutes.
- Stir in the balsamic vinegar and 3 1/2 cups beef stock. Bring to a boil on a high heat, then reduce the heat to medium and simmer for 5 minutes.
- In a separate small bowl, whisk together the remaining 1/2 cup beef stock and cornstarch until there are no lumps. Slowly pour the cornstarch slurry into the soup, whisking constantly until completely incorporated. Simmer for another 5 minutes.

Cooking by the Numbers…
Step 1 – Prep
Dice the onion, mince the garlic (or use a garlic press), chop the thyme, remove the stems and slice the mushrooms, and shred the meat with your hands or two forks.
I prefer larger chunks of meat to make a super hearty soup, but you can choose to shred it as finely as you would like.
Step 2 – Sweat the Aromatics
Heat the olive oil in a large pot over medium heat. Add the onion and saute for about 5 minutes, or until soft and translucent.
Add the garlic and thyme to the pot and saute for an additional 30 seconds, stirring constantly.
Don’t let the garlic brown, as it will continue to cook with the mushrooms in the next step.
Step 3 – Cook the Mushrooms
Add the mushrooms and continue to cook, stirring occasionally, until they are dark brown and have released their moisture, about 5 to 8 minutes.
Step 4 – Deglaze the Pan
Add the balsamic vinegar and 3 1/2 cups beef stock, scraping up any brown bits from the bottom of the pot.
Bring to a boil on high heat, then reduce the heat to medium and simmer for 5 minutes.
Is the balsamic vinegar too tangy for you? You can choose to omit it from the recipe. You will not need to substitute the two tablespoons with any more stock.
Step 5 – Thicken
In a separate small bowl, whisk together the remaining 1/2 cup beef stock and cornstarch until there are no lumps.
Slowly pour the cornstarch slurry into the soup, whisking constantly until completely incorporated. Simmer for another 5 minutes.
Step 6 – Add the Meat and Reduce
Add the beef to the pot. Continue to cook for 10 to 20 minutes, stirring occasionally, until the soup has reduced and thickened slightly, or to your liking.
Season with salt and pepper to taste. Transfer to serving bowls and garnish with chopped thyme.
Exactly How Much Should I Reduce the Liquid?
You can choose how much you want to reduce the broth in the final step of cooking. It all depends on what final consistency you prefer.
For a liquidy soup that you can have fun slurping, I recommend cooking the soup less, for no more than 15 minutes.
For a thicker and more condensed consistency that has all the comfort food vibes of a hearty stew, cook the soup for closer to 20 minutes in the final phase of cooking.
You can cook it for even longer if you love that rich texture! Just keep in mind that your yield will be smaller the more you reduce the soup.
Whether thin or thick, this soup is amazing served with a hunk of crusty bread for the best dipping device.
As long as you team up with equally comforting side dishes, you’ll have a meal that will give you so much delicious nourishment in the evening!
