One-Pot Creamy Cajun Chicken Pasta

One-Pot Creamy Cajun Chicken Pasta

You can’t go wrong with a one-pot meal. Less dishes are always a win in my book. One-Pot pastas not only are easier clean up, but the pasta gets cooked right with everything else so it gets infused with the flavor. One-Pot Creamy Cajun Chicken Pasta is slightly spicy but the creaminess from the cream cheese is the perfect pairing to the cajun spice.

Ingredients You’ll Need for this One-Pot Cajun Chicken Pasta:

  • Cajun Seasoning – see more about this below!
  • Chicken Breasts
  • Olive Oil
  • Onion – yellow or white
  • 1/2 box of short pasta – such as penne, farfalle, or rotini
  • Can of Fire Roasted Diced Tomatoes – you can substitute regular diced tomatoes as well
  • Cream Cheese
  • Sliced Green Onions
  • Can of Chicken Broth

The chicken breasts are cubed and tossed in the seasoning. Then the first step is to brown the chicken in a large deep skillet. A dutch oven would also work! The chicken does not need to be cooked through at this stage, but browning on the sides helps give lots of flavor.

Then the onion is added to soften for a few minutes before adding the pasta, chicken broth, and diced tomatoes. Bring to a boil, cover, and cook!

Once the pasta is cooked and has absorbed the liquid, stir in the cream cheese. This is what makes this dish nice and creamy with little effort! Sprinkle with sliced green onions and enjoy!

What is Cajun seasoning?

Cajun cooking originated in New Orleans and is a blend of many cultures. Seasoning blends vary blend to blend but they all have similarities. Cajun seasoning blends focus on spices, but often contain the herb oregano. The heat in the blend comes from cayenne pepper. Creole Seasoning is similar to Cajun, but it does not have the same spice level. If you don’t love spice, then go ahead and substitute a creole blend in this recipe!

How can I make my own Cajun seasoning blend?

Cajun seasoning is a very simple blend to make on your own. In fact, that’s what I usually do! I mix up a batch and keep it in a small mason jar so I always have some available. Here is a recipe – feel free to adjust the spice ratio to your preference. The spices you’ll need:

  • Garlic Powder
  • Salt
  • Paprika
  • Black Pepper
  • Onion Powder
  • Cayenne Pepper
  • Dried Oregano
  • Dried Thyme
