The Instant Pot is great for cooking a deliciously creamy sausage and potatoes casserole.
This creamy casserole is loaded with a huge range of flavors thanks to the smoked sausage, Dijon mustard, chicken stock, herbs, and cream. It is a super fulfilling dish that will easily satisfy a crowd.
A single batch of this casserole will feed roughly four to six people. I recommend doubling or tripling the recipe if you need to feed more people. Alternatively, some side dishes will help make the casserole go further.
The leftovers of this casserole are worth keeping but will need to be stored in the fridge or freezer. I recommend keeping leftovers for a maximum of three to four days in the refrigerator or three months in the freezer.
You can also slow cook this sausage and potato casserole if you want to prepare it earlier on in the day. The Instant Pot has a slow-cook function, or you can cook it in a dedicated slow cooker instead.
Side Dishes That Go Great with Casseroles
One of my favorite side dishes to serve with this casserole is some lovely homemade garlic bread. You can bake the garlic bread in the oven or use an Air Fryer. Both methods will work out great.
If you do not mind the extra carbs, some lovely freshly cooked rice will work great alongside the casserole flavors. I usually use a rice cooker, but cooking it over the stove or in the Instant Pot will work fine.
A light green salad is a fantastic side dish as it helps break up this very heavy casserole. I usually do a simple combination of cherry tomatoes, lettuce, red onion, feta cheese, cucumber, and avocado. Any salad dressing will work fine, but I love to keep it basic and use balsamic vinegar.
Some potato fries are perfect as a side dish if you feel like eating lots of comfort food. However, you may want to remove the potatoes from the casserole if you are worried about a potato overload. I recommend cooking the fries in an oven, air fryer, or deep fryer.
Tweaking the Recipe
Additional herbs can be added to the sauce for a bit more flavor. Basil, chives, thyme, rosemary, or even oregano will work great with the other ingredients.
Add a handful or two of shredded cheddar cheese in the last fifteen minutes of cooking for a cheesy sauce. Other cheeses such as cream cheese, provolone, or mozzarella will work great. You could even try a combination of cheeses.
You can add vegetables for more flavor and nutrition. For example, mushrooms, carrots, green beans, or even sweet potato will work great with the flavors of this dish.
Smoked sausages work fantastic in this casserole, but you can easily swap them for a different type of sausage. For example, Italian sausages are great but will require pre-cooking before you can easily slice them.

- I prefer to use a smoked sausage such as kielbasa or chorizo. However, Italian sausages will work great as well. I recommend browning the Italian sausages first.

- Depending on where you live, heavy cream can also be known as thickened cream (Australia) or whipping cream (United Kingdom).
- You can use herbs to add more flavor to the casserole. We use a little bit of parsley, but you can add herbs such as oregano, rosemary, or even thyme.
Note: I use a 5.7L (6 Quart) Instant Pot for all of the pressure cooker recipes I have on this website. If you have a smaller or larger pressure cooker, you may need to adjust the quantities in this recipe.
