Ingredients Equipment Method Notes

Ingredients
  

  • 500 g raw shrimp peeled and deveined
  • 2 tbsp butter
  • 3 cloves garlic minced
  • 1 cup heavy cream
  • 1/2 cup parmesan cheese grated
  • 2 tsp cajun seasoning
  • salt to taste
  • black pepper to taste
  • fresh parsley chopped (optional garnish)

Equipment

  • large skillet
  • mixing bowl
  • tongs or spatula
  • measuring cups and spoons
  • paper towels

Method
 

  1. Pat the shrimp dry with paper towels and toss lightly with Cajun seasoning.
  2. Heat butter in a large skillet over medium heat. Cook shrimp for about 2 minutes per side until pink and lightly golden. Remove and set aside.
  3. In the same pan, add minced garlic and cook for about 30 seconds until fragrant.
  4. Pour in heavy cream and simmer gently for 2–3 minutes. Stir in grated parmesan cheese until the sauce thickens.
  5. Return shrimp to the skillet and coat well in the sauce. Cook together for 1–2 minutes to blend flavors.
  6. Serve hot garnished with chopped parsley and extra parmesan if desired.

Notes

Pat shrimp dry before cooking for a proper sear. Use medium heat to prevent the cream sauce from separating. Adjust Cajun seasoning gradually to control spice level. Freshly grated parmesan melts better and thickens the sauce smoothly. Store leftovers in an airtight container for up to 3 days and reheat gently with a splash of cream.
