Ingredients Method Notes

Ingredients
  

  • Unsalted Butter, 1 stick
  • Heavy Cream, 1 cup
  • Cajun Seasoning, 2 tablespoons
  • Kosher Salt, 1 teaspoon (omit if seasoning is salted)
  • Parmesan Cheese, 1 cup (freshly grated)
  • Lemon Zest, 1 teaspoon
  • Non-dairy alternative: 1/2 cup coconut milk + 1/2 cup cashew cream
  • Vegan cheese alternative

Method
 

  1. Melt 1 stick unsalted butter in a large skillet over low heat
  2. Stir until foam diminishes, creating a smooth base
  3. Whisk in 1 cup heavy cream and 2 tablespoons Cajun seasoning
  4. Bring to a gentle simmer while whisking every minute for 5-6 minutes until thickened
  5. Test sauce consistency by tilting pan: it should coat the back evenly
  6. Remove from heat and add 1 teaspoon lemon zest
  7. Gradually whisk in 1 cup grated Parmesan until smooth and blindingly rich

Notes

Use European butter for thicker texture
Substitute pecorino for lactose-free option
Vegan version: replace cream with coconut milk + cashew blend and Parmesan with vegan cheese
Lemon zest enhances brightness without acidity
Sauce will thicken as it cools
