If you are a fan of Cajun and Creole flavors, you will love this Potato Casserole loaded with chunks of andouille sausage, seasoned with Tony Chachere’s Original Creole Seasoning.

If you’ve been following my recipes, you know that Tony Chachere’s seasonings are my go-to Creole and Cajun seasonings.

I use them in many of my recipes, such as Cajun Steak and Potato Foil Packs, Baked Cajun Fries with Cheese Sauce, Muffuletta Pasta Salad, and Blackened Shrimp Pasta. I just love their rich, gorgeous and complex flavors – they seriously make everything taste amazing!

Think of this as a classic potato dish with some of our favorite Cajun ingredients and flavors.

The potatoes are soft and creamy, coated in a cheesy rich sauce, while the andouille sausage and the Creole seasoning will remind you of some of your favorite Cajun dishes.

Whenever I bring this to parties or serve this for dinner, it gets DEVOURED.

Something about that magical combination of potato, cheese and a ridiculously good seasoning…yum!

This Cajun Potato Casserole with Andouille Sausage is such an accessible recipe that uses a short list of pantry-friendly and easy-to-find ingredients:

  • diced hash brown potatoes – these are found in the freezer section. They are usually sold in 2 lbs bags and are super convenient because they are already peeled and diced! It really doesn’t get easier than this!
  • smoked andouille sausage – these should be already-cooked sausage. Slice them into small slices
  • Tony Chachere’s Original Creole Seasoning – responsible for the amazing creole and cajun flavors in this dish. DO NOT SKIP THIS! A little bit of it goes a long way!
  • cream of chicken soup – this is the canned concentrated soup that will be responsible for bringing creaminess and flavors to our Cajun potato casserole
  • sour cream – also responsible for bringing creaminess to the dish. Unlike cream of chicken soup, it has a pretty neutral flavor when it is cooked
  • shredded cheese – I used mozzarella and cheddar, and find that Monterey jack works really well too. I would use whichever one you have at hand.

Note that we are not adding salt because Tony Chachere’s Creole Seasoning and the cream of chicken soup have salt in them.

Send it into the oven and bake at 350℉ for 1 hour.

When it is done, potatoes should be soft and creamy, the flavors from the andouille sausage and seasoning would have soaked through the sauce and potatoes, merging with that cheese to form the most delicious, melt-in-your-mouth gooey bites of cheesy potatoes.

Frequently Asked Questions

Can I use shredded hashbrown potatoes instead of diced hashbrown potatoes?

That works fine as well!

Should I thaw the potatoes before baking?

No. The 1 hour cook time assumes potatoes are frozen so you do not need to thaw the potatoes before baking.

How do I make my Cajun potato casserole less/more salty, less/more spicy?

Tony Chachere has different Creole Seasonings that are less/more salty or less/more spicy. Substitute one of them (No Salt Seasoning, Lite Creole Seasoning, BOLD Creole Seasoning, More Spice Seasoning, or Spice n’ Herbs Seasoning) for their Original Creole Seasoning and make the casserole according to your preference! You can find all of their seasonings at a store near you or at their online store.

    This was a great breakfast addition. I made it vegetarian by using cream of mushroom soup and veggie links sausages. Everyone loved it. So creamy and easy to make.

    Can this be made in an instant pot? I’d like to make this for a potluck the day before and need a way to reheat the day of.
