Ingredients & Substitutions
Butter: Use unsalted butter. If you're using store-bought Cajun seasoning, make sure to check its salt content to balance the flavors.
Shallot / Onion: I like to use shallots for their naturally sweet flavor in sauces, but onions can provide a stronger, spicier kick.
Garlic: Use the fresh cloves of garlic to make the paste.
Cajun Seasoning: This Alfredo sauce shines with the zesty kick of Cajun seasoning, creating a delightful blend that complements the creamy Alfredo perfectly.
Heavy Cream: For the authentic Alfredo taste and texture, heavy cream is essential. It brings a rich, smooth creaminess to the dish (you can substitute with full-fat milk if needed).
Parmesan Cheese: Shredded Parmesan adds a nutty, tangy, and bold flavor to the sauce. It's best to use pre-shredded cheese since shredding it at home can be tricky!
Parsley: Freshly chopped parsley adds a peppery note that pairs beautifully with the Cajun seasoning in the sauce.
Pasta water/broth (optional): Used to deglaze the sauce. Any broth or water can be used.
How To Make Cajun Alfredo Sauce
In a saucepan, add 2 tablespoon butter and heat it up on slow heat. As butter started to melt and forms bubbly texture, add 1 teaspoon fresh garlic paste. Sauté for few seconds and add chopped onion. Give a good stir and cook the onions until it become translucent.
Add 1 tablespoon Cajun seasoning and mix it well. Deglaze with pasta water or broth. Mix it well on slow heat and add heavy cream. Quickly stir the sauce for a few minutes to blend all the ingredients.
Now add 1 tablespoon butter to add a shiny smooth texture of sauce. Simmer the sauce for a minute on low heat. Add freshly grated parmesan cheese and mix it well.
Add freshly chopped parsley and again give it a good mix.
Monitor the sauce consistency. If it's runny cook it to get thick.
Blend the sauce with hand blender and serve.

Tips & Variations
- Thickness is the key to the best Alfredo sauce, which can be achieved by adding lots of Parmesan cheese.
- When preparing the sauce, it's essential to cook it over low heat while incorporating heavy cream to prevent curdling.
- The delightful combination of sautéed onion and garlic enhances the sauce's flavor, so be sure to use finely grated versions for a seamless blend.
- To achieve a smooth texture without stringiness, fresh parmesan is the way to go.
- Keep an eye on the sauce's consistency, as it tends to thicken once it reaches room temperature.
- When adding parmesan, maintain low heat and allow the cheese to melt gradually, stirring to ensure a creamy, thick result.
- For this creamy sauce, it's important not to replace butter with oil, as butter acts as a crucial binding agent for that desired creaminess.
- If you find the sauce too thin, continue cooking and stirring over low heat until it thickens; conversely, if it's too thick, a splash of broth or milk can help achieve the right consistency.
- If the sauce is separating, then blend it with a hand mixer. It will make it more smooth, rich, and decadent texture.
- The addition of freshly chopped parsley will add a herbaceous aroma to the sauce.
How To Store & Reheat
Store in Refrigerator: To keep your leftover Alfredo sauce fresh, place it in an airtight glass container and store it in the refrigerator for about 3 to 4 days.
If you have a smaller amount, simply transfer it to a small bowl, cover it with plastic wrap or aluminum foil, and pop it in the fridge.
When you're ready to use it, reheat the sauce in a saucepan, adding a splash of milk or broth to prevent it from burning and to help adjust its thickness.
Freezing: I don’t recommend freezing it for a long time but still if you are a busy mom or dad, store it in an airtight freezer-friendly bag or container.
When you're ready to enjoy it again, let it thaw completely at room temperature, then reheat it slowly in a saucepan, adding a bit of milk or broth to achieve the desired consistency. Remember to stir it occasionally during the reheating process to ensure it warms evenly.
