This is an easy dinner recipe. To keep it quick and to add some protein to this pasta, we like to bake breaded chicken breasts and place on top of this pasta or on the side of this pasta dish. Costco has delicious chicken patties that we use a lot. They work well with this dish along with many others. They are fantastic on salads, in a bun for a chicken sandwich-topped with barbecue sauce or ranch dressing, and alone with some vegetables.

We have many easy recipes on our on-line recipe book. Along with some that are more time consuming, but still very delicious.

Instructions for Creamy Cajun Pasta:

Cook the pasta according to package directions with a dash of salt until just done-11 minutes. Drain and set aside.

Melt the butter in a skillet over medium heat and add the onion. Sauté until the onion is tender.

Mince the garlic, add to mixture, and stir to combine.

Stir the flour into the onion mixture, this will make a paste like consistency.

Add the chicken broth and Cajun seasoning, salt, and pepper. Bring to boil and simmer until sauce thickens. Stirring to combine broth and the flour mixture.

When sauce has thickened, reduce the heat and continue stirring. Allow time for the sauce to stop boiling-just simmering.

Stir in the half and half. Stir and let the sauce return to a simmer over low to medium heat. We want the half and half to heat through and thicken at a low boil.

As the sauce is thickening, add the parmesan cheese and mix well to combine.

When sauce is the desired thickness, remove from the heat and add the lemon juice. Stir to combine.

Pour the creamy cajun sauce over the drained pasta and stir to coat.

Top with some parsley and more grated parmesan, if desired. I like how the extra parmesan and parsley flakes look on top of this pasta-it looks pretty and very appetizing.

Something to remember when using dairy in some recipes, it is important that you warm the dairy up slowly and let it simmer. Do not allow sauce to boil rapidly. For example, a queso recipe we love, if I get the queso too hot after I add the milk, it will separate-you don’t want that!!

  1. How can I avoid the half and half curdling when added to the lemon juice mixture?

    1. Hi Amber, I am so glad you reached out. If you have a picture of your finished dish, I would love to see it ( I am sorry to hear your half and half curdled. I think, when you added the half and half, the heat was too high. We want the dairy to heat through but not come to a boil. If the dairy heats too quickly or boils, it can curdle. Do you remember if it boiled? How did it taste? Another option that has helped me with soup…warm your dairy slowly in another sauce pan so it doesn’t go into your pasta dish or soup cold. I so appreciate your feedback!! I hope to hear back from you. Hopefully, you and your family are all safe and healthy. 😊
