Ingredients

  • 2 tablespoon Butter unsalted
  • 1 teaspoon Garlic Paste
  • 2 tablespoon Onion Chopped
  • 1 tablespoon Cajun Seasoning
  • cup Pasta Water To deglaze
  • 1 Cup Heavy Cream
  • Cup Parmesan Cheese
  • 1 tablespoon Parsley Chopped

Homemade Cajun Seasoning

  • 1 tablespoon Paprika Powder
  • teaspoon Cayenne Pepper
  • teaspoon Black Pepper
  • teaspoon White Pepper
  • ½ teaspoon Onion Powder
  • ½ teaspoon Garlic Powder
  • teaspoon Dried Oregano
  • teaspoon Dried Thyme
  • ½ teaspoon Salt

Instructions

  • In a saucepan, add 2 tablespoons butter and heat it up on slow heat. As the butter starts to melt and forms a bubbly texture, add 1 teaspoon of fresh garlic paste. Sauté for a few seconds and add chopped onion. Give a good stir and cook the onions until 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.

Notes

Quick Tips To Make Perfect Sauce
  • Use fresh Parmesan for a creamy, non-stringy texture.
  • Add cream on low heat to prevent curdling.
  • Sauce too thin? Simmer longer. Too thick? Add a splash of milk or broth.
  • If it separates, blend with a hand mixer.
  • Finish with butter + parsley for extra creaminess and freshness.
