How to Make Creamy Cajun Chicken Pasta

- Boil Pasta. Cook the pasta in a large pot of salted water to al dente according to package instructions.

2. Cook the chicken. Season the beaten chicken breasts and sear on both sides. In a skillet, sear the chicken on both sides, then turn the heat down and cook it over low heat for 5 minutes or until it is cooked through. Remove from the pan, chop into bite-sized pieces, cover, and set aside to keep warm.

3. Cook veggies. To the same pan, add sliced mushrooms and butter: saute, then add minced garlic and diced tomatoes.
Make alfredo sauce. Turn the heat down to low and add heavy whipping cream, parmesan cheese, and remaining cajun spice. Stir to combine and bring up to a simmer and cook until the sauce begins to thicken.

4. Combine. Add the cooked pasta to the sauce and toss lightly to combine. Top with extra grated parmesan cheese and fresh parsley, and serve!
Expert Tips:

Though chicken tastes incredible in this dish, you can easily swap it out for a variety of proteins! Juicy cajun shrimp or andouille sausage for a delicious cajun flavor.

Store & Reheat
- Storage. Keep leftovers in an airtight container and store them in the fridge for up to 3 days.
- Reheat. To warm up leftovers, add the pasta to a warm pan, add a little water, and cover with a lid. The sauce will thicken in the fridge, and as it is reheated, it should become creamy again. The noodles also absorb the sauce, and if they are too dry, you can add a splash of heavy cream to help give them that creamy consistency again.
- Freeze. We don’t recommend freezing this recipe as the sauce can begin to separate.
