Ingredients:

  • 3 sticks (1.5 cups) unsalted butter
  • 4 Tbsp shallots, finely minced
  • 4 Tbsp garlic, minced
  • 1/4 cup Cajun seasoning blend (e.g., Tony Chachere's)
  • 2 Tbsp smoked paprika
  • 2 Tbsp tomato paste
  • 1 tsp cayenne pepper
  • 1 Tbsp brown sugar
  • 1/2 cup low sodium chicken broth
  • 2 Tbsp fresh lemon juice

Instructions:

  1. Melt the butter: Place the 3 sticks of butter into a heavy-bottomed pot or saucepan over medium-low heat. Allow it to melt slowly without browning.
  2. Sauté Aromatics: Add the minced shallots and garlic to the melted butter. Cook gently for 3–4 minutes until they soften and become highly fragrant, ensuring they do not crisp or burn.
  3. Bloom Spices: Stir in the Cajun seasoning, smoked paprika, cayenne pepper, and brown sugar. Continue cooking and stirring for 2–3 minutes. This crucial step blooms the spices, releasing their aromatic oils and dissolving the fat-soluble flavor compounds completely into the butter, developing the deep color and rich flavor.
  4. Build Base: Whisk in the tomato paste until it is fully incorporated into the spiced butter mixture, about 1 minute.
  5. Emulsify: Slowly whisk in the chicken broth and lemon juice. Increase the heat slightly and continue whisking until the sauce emulsifies and achieves a smooth, opaque, and velvety consistency. Simmer gently for 2–3 minutes to finish the cooking process. Serve immediately over prepared seafood boil ingredients.
