Need an easy and delicious dinner idea this week? Give this Cajun Chicken and Shrimp Alfredo a try! It takes my Homemade Alfredo Sauce recipe and pairs it with your favorite pasta, chicken, shrimp, veggies, and Cajun seasoning.

I love putting Cajun seasoning on all sorts of things. We sprinkle it on our potatoes, meat, fish/seafood, sauces/dips (even put some in our popular Boom Sauce sometimes), burgers… you name it.

What is Cajun Seasoning?

So like everything, Cajun seasoning can vary quite a bit depending on the brand (or if you make it yourself). It can include spices such as red pepper, onion powder, garlic powder, black pepper, salt, thyme, celery seed, cayenne, and paprika.

It’s generally on the spicy side, but if you use just a little it’s not too spicy. Use a lot, and definitely can feel the heat! The heat level though can vary between brands as well, so I always suggest using just a little Cajun seasoning at first then add more if you’d like.

You can easily change up a lot of the ingredients with whatever you have around the house including precooked chicken (or see my How to Make Shredded Chicken) that you may have leftover.

I used my Homemade Alfredo Sauce, but you could also use this Alfredo Sauce with Cream Cheese if you’d prefer.

Cajun Chicken and Shrimp Alfredo Ingredients

• Fettuccine pasta or your favorite kind
• Onion
• Bell pepper
• Chicken, boneless skinless breasts
• Shrimp
• Cajun seasoning (I use McCormick’s but you can use your favorite brand)
• Butter
• Garlic
• Heavy Cream
• Parmesan cheese, good quality freshly grated

How to Make Cajun Chicken and Shrimp Alfredo

1. MAKE PASTA. Bring a large pot of water to boil and cook pasta according to box directions for al dente.
2. COOK CHICKEN & VEGGIES. Meanwhile, cook onion, pepper, and chicken in a large nonstick skillet (or skillet sprayed with nonstick spray or a little olive oil) over medium heat for about 2-4 minutes or until vegetables are just about soft and chicken starts to brown and nearly cooked through. Add shrimp and 1 teaspoon Cajun seasoning, and cook an additional 3-5 minutes or until chicken and shrimp are cooked through. Set aside.
3. MAKE ALFREDO SAUCE. Place a large pot over medium heat. Melt butter, then stir in minced garlic cloves. Cook about 1 minute or until garlic is soft and fragrant, stirring constantly.
4. Slowly add the heavy cream to the saucepan, whisk until cream comes to a boil. Reduce heat and simmer about 3-5 minutes or until it starts to thicken.
5. COMBINE. Stir in Parmesan cheese and 1 teaspoon Cajun seasoning until smooth and thick. Add more Cajun seasoning as desired. Stir in onions, peppers, chicken, shrimp, and drained cooked pasta. Serve immediately.

Serving Suggestions

• I’d suggest topping the pasta with a little fresh chopped parsley and/or freshly grated parmesan cheese before serving.
• For best results, serve right away. Alfredo sauce generally tastes better when it’s fresh and not reheated.
• This pasta dish would be great with a salad and/or homemade bread like these homemade Fluffy Buttermilk Chive Biscuits or this easy Beer Bread.
• A side vegetable would also be delicious with this pasta such as steamed broccoli or even these Italian Green Beans or Roasted Brussels Sprouts. Or add a little Cajun seasoning to your favorite green veggie!

Quick Tips for Best Results

• I would recommend serving this pasta dish right away. You can reheat leftovers, but they might not be as delicious. Still good though!
• Use any kind of pasta you’d like, but make sure you adjust the pasta cooking time as needed.
• Be sure the chicken and shrimp are thoroughly cooked before mixing with the pasta.
• Cajun seasoning can vary quite a bit and some are spicier than others so you may need to adjust the amount to your personal taste.
• If you like a lot of pasta and/or sauce, you might want to double either or both in the recipe. Some people may find the serving size a bit on the small side. Likewise, if you prefer A LOT of sauce, you may want to double the sauce recipe. Personal preference.
