Ingredients
  

For the Aromatics
  • 2 tbsp Unsalted Butter
  • 1/2 cup Yellow Onion finely diced
  • 1/2 cup Green Bell Pepper finely diced
  • 1/4 cup Celery finely diced
  • 3 cloves Garlic minced
For the Seasoning
  • 2 tbsp Cajun Seasoning (adjust to taste, ensure it's salt-free if adding salt separately)
  • 1 tsp Smoked Paprika
  • 1/2 tsp Dried Thyme
  • 1/4 tsp Cayenne Pepper or more, to taste (optional, for extra heat)
  • 1/2 tsp Salt or to taste
  • 1/4 tsp Black Pepper freshly ground
For the Sauce Base
  • 1/2 cup Chicken Broth low sodium
  • 1.5 cups Heavy Cream
  • 1/4 cup Parmesan Cheese freshly grated (optional, for extra richness)
For Garnish
  • 2 tbsp Fresh Parsley chopped (optional)

Equipment

  • Large skillet or sauté pan
  • Whisk
  • Measuring cups and spoons
  • Cutting board
  • Sharp knife

Method
 

Prepare the Aromatics
  1. Melt 2 tbsp of unsalted butter in a large skillet or sauté pan over medium heat.
  2. Add the finely diced yellow onion, green bell pepper, and celery (the 'holy trinity') to the skillet. Sauté for 5-7 minutes, stirring occasionally, until the vegetables are softened and translucent.
Build the Flavor Base
  1. Stir in the minced garlic and cook for another 1 minute until fragrant. Be careful not to burn the garlic.
  2. Add the Cajun seasoning, smoked paprika, dried thyme, cayenne pepper (if using), salt, and black pepper. Cook for 1 minute, stirring constantly, to toast the spices and enhance their flavor.
  3. Pour in the chicken broth, scraping up any browned bits from the bottom of the pan with a wooden spoon. Bring the mixture to a gentle simmer and let it cook for 2-3 minutes, allowing it to reduce slightly.
Create the Creamy Sauce
  1. Reduce the heat to low. Gradually whisk in the heavy cream until it is fully incorporated and the sauce is smooth.
  2. Bring the sauce to a very gentle simmer (do not boil vigorously), stirring occasionally. Let it thicken for 5-7 minutes until it coats the back of a spoon.
  3. If using, stir in the freshly grated Parmesan cheese until it is melted and smooth. Taste the sauce and adjust seasoning (salt, pepper, or more Cajun seasoning) as needed.
Serve
  1. Remove the Cajun Cream Sauce from the heat. Serve immediately over your favorite pasta, grilled chicken, pan-seared shrimp, or fish. Garnish with fresh chopped parsley if desired.

Notes

For a vegetarian version, substitute chicken broth with vegetable broth. If the sauce becomes too thick while reheating, thin it with a splash of warm chicken or vegetable broth or a bit more cream. Store leftover sauce in an airtight container in the refrigerator for up to 3 days. Reheat gently over low heat.
