Instant Pot Potato Sausage Casserole
Mmmm! This easy potato sausage casserole is so tasty and a great one pot meal! My family loved it and the pot was scraped clean. The smoked sausage gives it great flavor. I think that you’ll also love the addition of corn and carrots. I’ll be making this recipe again soon!
Ingredients/Substitution Ideas
- Red potatoes–you can also use Yukon gold potatoes
- Carrots–you can also use baby carrots
- Olive oil–or canola oil
- Beef smoked sausage–or another type of smoked sausage (kielbasa, andouille)
- Chicken broth–or beef broth
- Sour cream–or plain yogurt
- Onion powder
- Garlic powder
- Black pepper
- Kosher salt
- Dried rosemary
- Dried basil
- Dried thyme
- Corn–I used canned corn, frozen also works. If you use frozen corn add it in the steamer basket on top of the carrots.
- Cheddar cheese–or another type of cheese you like
The Basic Steps
- Pressure cook the potatoes and carrots in a steamer basket. I love my avokado silicone steamer basket*.
- Brown the sausage. The sausage is already cooked but this just adds a little color and flavor to it.
- Toss potatoes, carrots, sausage and corn with sour cream, seasonings and cheese. Stir gently so the potatoes stay intact and don’t become mashed potatoes.
- Eat and enjoy!
Notes/Tips
- Serve with a green salad or some asparagus, brussels sprouts or broccoli.
- I used my 6 quart Instant Pot*. You can also make this in an 8 quart pot.
- If you don’t have a steamer basket* then try using a trivet to get most of the potatoes and carrots off of the bottom of the Instant Pot. This will prevent the potatoes from getting grainy.
- This recipe is gluten free (make sure broth is labeled gluten-free).
- Store leftovers in an airtight container* in the refrigerator for up to 5 days or in the freezer for up to 3 months.
- Other recipes you can make with red potatoes are Awesome Wife Casserole and Instant Pot Parmesan Ranch Potatoes.

the spices in this are great. I cooked an onion with the sausage because why not, and I was almost out of sour cream so I subbed in some cottage cheese which works with everything.
★★★★★
love the idea of cottage cheese!
It was good with unpeeled russets and Greek yogurt.

Thanks Sharon for the 5 stars!
when do you add in the corn?
nevermind. I see it now. 🤦
Karen, do you think sliced Italian sausage links would work with this recipe? Thank you.
Yes! Sounds great 🙂
What do you do with the potatoes? Slice or cut in small pieces.
Oops sorry! I just added that info. You’ll want to cube them into 1 inch cubes
