Creamy Cajun tortellini soup for a cozy and comforting quick and easy weeknight dinner! Chock full of tender cheese tortellini, flavorful andouille sausage, spicy Cajun seasoning and spinach. So freaking good!

If you know me at all, you know I love spicy. Not just heat level, but flavor, too. So it's no surprise that my favorite spice blend is Cajun seasoning. I love the stuff! And I'm always down for creamy, comforting homemade soups, especially when the weather turns cooler.

This Cajun tortellini soup is inspired by my favorite creamy tortellini soup from Damn Delicious made with Italian sausage and kale. I spice things up with a Cajun flavor profile ~ andouille sausage and Cajun seasoning ~ creamy and spicy and deliciously satisfying!

HERE'S WHAT YOU NEED

olive oil
andouille sausage
onion, garlic, Cajun seasoning
salt and pepper, a little flour for thickening
chicken stock or broth, preferably homemade
tomato sauce
a package of refrigerated three cheese tortellini
baby spinach
a little heavy cream
fresh parsley
grated Parmesan for serving

WHAT IS CAJUN SEASONING?

Cajun seasoning or Creole spice mix is a blend of several herbs and spices. You’ll often see Cajun and Creole used interchangeably, but they basically cover the same flavor profile ~ garlic, onion, salt, pepper, cayenne pepper, paprika, oregano and thyme. I use an unsalted local store blend or you can easily make your own. Here is the recipe I use from Immaculate Bites for making your own Creole Cajun Seasoning.

STEP BY STEP INSTRUCTIONS

Step 1: Cut the andouille sausage into coins and caramelize a bit in olive oil. Add onion, garlic and Cajun seasoning, cook until translucent and then add flour and stir and cook for a minute or so.

Step 2: Whisk in chicken stock and tomato sauce and bring to a boil and simmer until reduced and thickened a bit.

Step 3: Stir in the tortellini and cook until tender, then add the spinach and cook a couple minutes until wilted.

Step 4: Lastly, stir in the cream and parsley, heat through and season with salt and pepper. Ladle into bowls and serve with some grated Parm on top!

RECIPE NOTES AND TIPS

Andouille sausage is easily found in the grocery store and is fully cooked. You'll likely find national brands, and here in St. Louis several local brands. The local brands are usually spicier, and lately I've been using a chicken andouille sausage. If you can't find andouille at all, any smoked fully cooked sausage links will work.
I highly recommend an unsalted Cajun seasoning blend and then you can adjust for salt. Blends with salt are usually just too salty! The homemade mix I make has no salt at all and tastes just like the unsalted blend I buy from the bulk spice section at my local grocery.
Homemade chicken stock is simply the best if you have it. I almost always have some in my freezer. I save all my chicken scraps and bones in a bag in the freezer, then make chicken stock in my Instant Pot whenever I need it. So easy and it makes such a difference in all my recipes, from soups to stews to sauces.
Since it's usually just the two of us, this soup freezes beautifully! I freeze enough for another meal down the road, I love having soup in the freezer!
Feel free to adjust the amount of Cajun seasoning to your spice comfort level. You don't want your mouth on fire! The amount in the recipe is the perfect balance of heat and flavor, but you do you if it's too much or not enough!
Serve with a generous sprinkling of grated Parmesan and maybe some crusty bread and a simple green salad. This soup comes together quick and easy for a homemade weeknight dinner in about 45 minutes!

I hope you try this creamy and spicy tortellini soup, I think you will love it! And did I mention you can get this on the table in under an hour? Oh I did, so now you know. Creamy Cajun Tortellini Soup for the win! Kelly🍴🐦
