Ingredients Method Notes

Ingredients
  

  • 16 oz uncooked pasta
  • 1 shallot minced
  • 2 tablespoon butter
  • 4 garlic cloves minced
  • 8 oz full fat cream cheese
  • 1 cup heavy cream
  • ½ cup parmesan cheese extra for garnish
  • ½ cup salted pasta water
  • 3 tablespoon No salt cajun seasoning
  • Salt to taste
  • Minced parsley garnish

Method
 

  1. Place your pasta of choice in a dutch oven or large pot and cover with water. Salt your water generously. Set the heat to medium high and boil your pasta until aldente.
  2. Strain out your cooked pasta and reserve about ½ cup of salted pasta water.
  3. In the same pot you cooked your pasta place your butter and shallots. Once the shallots are translucent add the garlic, cream cheese, reserved pasta water, heavy cream, parmesan and cajun seasoning. Set to medium low heat and stir until the parmesan is fully melted and the cream cheese is completely incorporated.
  4. Once your cajun alfredo sauce is ready, fold in your cooked pasta and stir to fully coat the pasta noodles in the cream cajun sauce. If you see your pasta sauce is drying out, add a splash more cream to it and continue to mix.
  5. At this point, your dish is done, serve directly from the pot or place the pasta in a serving bowl and garnish with additional parmesan cheese and minced parsley.

Notes

Cajun Alfredo Pasta Recipe Variations

  • Add some protein to this pasta like shrimp, blackened chicken, andouille sausage or salmon
  • Want to add some vegetables? Broccoli, bell peppers, onions and even peas would be great additions to this dish
  • Don't want your cajun pasta to be too spicy? Minimize the amount of spice you add to your personal preference.
  • Prefer long noodles? opt for fettuccini or spaghetti instead of penne pasta.
  • Don't want to make your own cajun seasoning? Use your favorite store bought seasoning blend like Slap Ya Mama or Tony Chachere's. Just keep in mind the salt content of those storebought blends when adding them to your alfredo sauce.

How to store Homemade Cajun Alfredo Sauce with Pasta

Step-by-Step Instructions

  1. Let it cool first
    Allow the pasta to cool at room temperature for about 20–30 minutes. Don’t leave it out longer than 2 hours.
  2. Use airtight containers
    Transfer the pasta into a sealed container to keep moisture in and odors out.
  3. Refrigerate promptly
    Place it in the fridge at or below 40°F (4°C).

Shelf Life

  • Stays fresh for 3 to 4 days in the refrigerator.

Can You Freeze Cajun Alfredo Pasta?

Yes—but with caution.

Freezing Tips

  • Use freezer-safe containers or heavy-duty zip bags.
  • Remove as much air as possible to prevent freezer burn.
  • Label with the date.

Shelf Life in Freezer

  • Best used within 1 to 2 months for optimal taste.

Important Note

Cream-based sauces like Alfredo can separate or become grainy after freezing. Stir well when reheating, and consider adding a splash of milk or cream.

Reheating Instructions

On the Stove (Best Method)

  • Add a splash of milk, cream, or even a little water.
  • Heat on low, stirring frequently to restore creaminess.

Microwave

Stir between intervals and add liquid if needed.
Place in a microwave-safe dish.
Cover loosely and heat in short intervals (30–60 seconds).
