There is nothing better than soup, it’s my ultimate comfort food. My favorite of all soups? Pot roast soup.
I love a beef broth-based soup that’s hearty in vegetables. For this recipe, I made the pot roast soup in the Ninja Foodi (my favorite kitchen appliance) but I have instructions for a pressure cooker (InstantPot) and a slow cooker as well.

I bought my Ninja Foodi this past Amazon Prime Day and let me tell you, this baby gets used all the time. It’s a pressure cooker, slow cooker, air fryer, roaster, a few more things all in one. I really like how you can crisp your food up after pressure cooking and/or slow cooking. It’s perfect for quick wings or buffalo cauliflower bites.

Anyway, before I carry on and on about how much I love this kitchen tool…let’s get to the recipe and some helpful tips to help you get the most out of this recipe.
What’s the difference between pot roast and roast beef?
Essentially pot roast soup is a hearty beef and vegetable soup. Pot roast itself is cooked in liquid and that’s the main difference between pot roast and roast beef.
Can I use leftover beef in soup?
Of course, I highly encourage it as it reduces potential food waste. This particular recipe I used leftover brisket from Christmas dinner but you can use leftover chuck roast, sirloin roast, etc.
If you don’t have any leftover beef you can use stew meat. I recommend you sear it first to lock in some flavor and start breaking down the fat. It should end up nice and tender by the time you cook it in the pressure cooker.
How you thicken beef soup?
I keep soups fairly broth based but if you would like a thicker soup you can whisk in flour, arrowroot powder, or a bit of cornstarch (shake up the flours/starches with broth or water first before you add it so it mixes in well).
The soup itself will thicken naturally as it cooks but it’s all a personal preference so do what you need to do to make it work for you.
Is beef soup healthy?
Beef gets a bad rap, but it shouldn’t. Yes, it’s higher in saturated fat but as the saying goes – everything in moderation.
Beef is a healthy food to have in your diet. Again, in moderation.
The health benefits of beef are:
- High in protein (depending on the cut there is roughly 26g of protein in 3.5oz).
- A source of vitamin B12, B3, and B6.
- A source of zinc, iron, selenium, and a few other minerals.
Combine some of those health benefits with the hearty vegetables added to the soup, and throw in the fact that you’re upping your fluids with the broth. This pot roast soup is a delicious way to fill up and enjoy a fantastic healthy dinner recipe.
How many calories are in pot roast soup?
There are roughly 239 calories in 1/10th of this recipe. I say roughly as everyone’s vegetables may be different sizes, different brands of broth, etc. However, the count will be close.
There are only 5 grams of carbs per serving, which makes this pot roast soup a low carb recipe (and it qualifies as a keto diet recipe for those of you looking for recipes that would qualify for that as well).
The fat content will change depending on the cut of beef you used. I used leftover brisket, which is quite fatty so the fat content will vary depending on the meat you want.
That being said, I’m a firm believer in having a rough estimate of what you’re eating. It doesn’t always have to be black and white. I teach more about that in the 30 Days to a Healthier You Challenge. You can register for the nutrition challenge or learn more about that here.
How to make beef vegetable soup low carb
A question I am often asked is how to make recipes low carb.
I generally don’t add noodles, rice, quinoa, potatoes to my soups and that’s my version of low carb. I keep it simple with veggies and beef.
If you want to lower the carbohydrate count even further, then you will have to look at the vegetables I added (carrots, green beans, celery, etc) and see what you can leave out or swap. That being said, I personally don’t recommend this route.
These are vegetables that are good for you, keep them. They provide nutrients for your body and they help make the soup what it is. Besides, with the vegetables, I have added one serving is roughly 5g of carbs. It’s low enough already.
What vegetables go good in beef soup
The other route you could go is to add whatever vegetables you have in the fridge to make this recipe your own. I’ve included the vegetables I’ve used plus a few others that I think would go great.
Feel free to experiment! Cooking is all about winging it.
- Green beans
- Bell peppers

Pressure Cooker Pot Roast Soup
- Instant Pot
- Slow Cooker
- 2 tbsp avocado oil
- 1 onion diced
- 2 celery stalks diced
- 3 carrots peeled and diced
- 3 garlic cloves minced
- 3/4 cup red wine
- 1 cup green beans I used frozen
- 1/2 tsp fresh rosemary
- 1 14oz can fire roasted tomatoes
- 4 cups beef broth
- 3 cups beef cooked (I used leftover brisket, but you can use whatever leftovers on hand or 1 1/2 lbs of raw stew meat).
- 1 ts salt
- 1 tsp pepper
- 2 tsps oregano
- 1 tbsp gluten free flour or regular flour, optional (see notes)
For the NinjaFoodi/InstantPot/Pressure Cooker
- Turn on the saute feature and add the avocado oil. Please see the notes below if you're using raw stew meat.
- Add the onions, carrots, and celery and saute until the vegetables have softened up (the onions should be almost see-through). Add the garlic next, stir until fragrant (about one minute).
- Add the wine. Let it simmer a bit and reduce down, I let this go for about 3-5 minutes.
- Add the rest of the ingredients. Turn off the saute feature and place the pressure cooker lid on top of the cooker.
- Turn the valve to seal, and turn on manual pressure on high for 25 minutes.
- Once it's done you can release the pressure manually but full disclosure: I totally forgot about it for an hour so it released on its own. Either or is fine.
Slow Cooker Instructions
- Add everything to the slow cooker (see notes below for a browning option) and turn the heat to low. Cooker for 8-10 hours.
Stove top Instructions
- Follow the pressure cooker instructions. However instead of adding the lid and sealing, bring the soup to a boil, then cover with a lid and reduce it to a simmer.
- Let the soup simmer for 45 minutes, but the longer the better. I like to simmer for 1-2 hours depending on how much time I have.
Stew Meat InstructionsPressure Cooker Instruction Notes: If you are using raw beef (stew meat) I recommend browning it first. Add the beef to the pan before the veggies and brown. Remove it and place it on a plate somewhere, then follow the instructions above. Add the beef back in after. Slow Cooker Instructions: You have the option to brown the meat as well but the slow cooker should break down the beef until tender.
Flour InstructionsIf you would like the soup a little thicker, you can add a tablespoon of flour (or gluten free flour) mixed wth some beef broth to thicken. Simply thicken it to your liking.
