Broccoli Potato Soup Instant Pot Ingredients
- Chicken stock – I use frozen chicken broth, no need to thaw it!! If you don’t have homemade stock, “Better than Bullion” chicken stock concentrate is another great option.
- Potatoes – I love using leftover baked potatoes in this recipe. But you could also use about 2lbs raw russet potatoes.
- Broccoli – Both fresh or frozen broccoli works. If using frozen broccoli, take it out of the freezer as you start cooking.
- Milk – For richer flavor, use whole milk. But 2% milk works fine too!
- Cornstarch – Helps to thicken the soup.
What type of potato is best for potato soup?
You can use any leftover baked potatoes that you have on hand for this recipe. Any variety will work well.
If you don’t have leftover baked potatoes, you can also use raw russet potatoes. If you cut them into small cubes, they will cook thoroughly and work well in this broccoli potato soup.
Can I use frozen broccoli instead of fresh for soup?
You can use fresh or frozen broccoli as they both work equally well, so use what you have on hand. I always have some frozen broccoli in the freezer, as it’s super convenient, and I highly recommend you keep a bag or two as well.
If using frozen broccoli for your broccoli soup, remember to take it out on the counter to thaw slightly as you start cooking the dinner.
How to make Broccoli Cheddar Potato Soup
Making this potato soup recipe couldn’t be easier!
- You start by adding the frozen chicken stock to the Instant Pot to thaw slightly. Fresh chicken stock will work just fine too, simply continue with the recipe without waiting for the stock to warm up.
- Once that has started thawing and there is about a cup of liquid stock that has melted, you add in the potatoes and seasoning.
- We add broccoli florets after pressure cooking the potatoes, because otherwise they come out super over cooked.
- Then we’ll add milk for extra creaminess and cornstarch slurry to thicken the soup.
- And lastly, stir in the cheese and serve!
A creamy, comforting dinner in less than 45 minutes that the whole family can tuck into!
How to serve Potato Broccoli Cheese Soup
Serve the broccoli soup with additional shredded cheese on the side. You can also serve it with cooked bacon and crackers.
Can you freeze broccoli potato cheese soup?
Most soups freeze well and can be reheated with no issues. However, as this soup has cheese and potatoes in it, it might be more difficult to get a good result when reheating.
Potatoes come out mushy and gummy when reheated from frozen due to their high moisture content. If you would like to try and freeze this soup, perhaps keep the potatoes separate or under cook them beforehand so that they cook more when being reheated.
The cheese in this broccoli cheese soup might also cause an issue when reheating as dairy can often separate when being reheated from frozen. If you have frozen this soup and want to reheat it, reheat it very gently over low heat. This should help prevent separation.
Another tip is to freeze the soup into smaller individual portions. This helps them freeze faster with fewer water crystals forming. This helps the structure of the soup and the soup will have a better texture when reheated.
Instant Pot Broccoli Potato Soup FAQs
Mix cornstarch with a little bit of water to make a cornstarch slurry, and add it into a boiling soup. Let the soup boil for a few minutes to thicken.
Stir in the cheese once the soup is fully cooked and off the heat.

Broccoli Potato Cheese Soup (Instant Pot)
- 3 cups chicken stock Note 1
- 2-3 leftover baked potatoes Note 2
- 1 teaspoon salt
- 1 teaspoon garlic powder
- 6 cups frozen broccoli florets Note 3
- 1 cup whole milk
- 1 tablespoon cornstarch
- 1 cup grated cheddar cheese more for serving
- Place the inner pot in Instant Pot and hit “saute” button. Add broth and warm it up. If you’re using frozen stock, put it in as frozen and start thawing it in the pot.
- Meanwhile, cut the potatoes into small cubes. (I use this handy tool to expedite the process.)
- Add the potatoes, salt and garlic powder into the pot with chicken stock. (If you’re using frozen stock, no need to wait for the stock to fully thaw, but make sure there’s at least 1 cup of liquid thawed.)
- Cover and make sure the valve is set to sealing. Click “cancel” button, and then Manual/Pressure Cook button. Set it for 3 minutes on High. (Note: It took 24min for IP to come to pressure with some frozen stock.)
- Once the time is up, let the Instant Pot release pressure naturally for 5 minutes. Then turn the valve to venting to release all the remaining pressure. When the pin drops, carefully open the lid.
- Hit “saute” button, add broccoli and milk. Bring it to a boil.
- Meanwhile, in a small bowl, mix cornstarch with 1 tablespoon of water. And add it to the soup while it’s boiling. Mix everything well and cook until broccoli is softened.
- Add cheese and stir until it’s fully melted. Serve with more cheese, if desired.

I followed the recipe but there seems to be too much liquid at the end ?? How do I fix that
Hi, Myranda. Once you add cornstarch slurry in and let the soup boil for a few minutes, it thickens up nicely.
I emulsified half of it right in the pot before I added the cheese… Fantastic!!
Thank you for your feedback, Patricia. So happy you loved it!
Could i use frozen broccoli? If so how to incorporate it?
Hi, Christine. Yes, frozen broccoli will work just fine. If using frozen broccoli for your broccoli soup, remember to take it out on the counter to thaw slightly as you start cooking the dinner. Then proceed as directed, no adjustment necessary.
