Step‑by‑Step Instructions for Seafood Boil Sauce

Step 1: Melt the Butter
In a large skillet, melt 1 cup of salted butter over medium heat until it becomes bubbly and fragrant, about 2-3 minutes. This rich and creamy base is essential for your Seafood Boil Sauce. Make sure to watch closely to avoid browning the butter, which can change the flavor.

Step 2: Sauté the Onion
Once the butter is melted, add 1 finely diced onion to the skillet. Sauté the onion for about 5 minutes, stirring occasionally, until it turns translucent and slightly caramelized. This step infuses the sauce with sweetness and depth, creating a beautiful foundation for your seafood.

Step 3: Add the Garlic
Stir in 4 minced garlic cloves and cook for an additional 2-3 minutes until fragrant, continuously stirring to prevent burning. The aroma will be delightful! This addition amplifies the flavor profile of the Seafood Boil Sauce and brings that essential punch to your dish.

Step 4: Spice It Up
Now, mix in 1 tablespoon of Cajun seasoning, 1 tablespoon of Old Bay seasoning, 1 teaspoon of onion powder, ½ teaspoon of red pepper flakes, and 1 tablespoon of brown sugar. Cook the spices for about 5 more minutes, stirring well to combine and release the flavors. Your sauce is transforming into a warm, aromatic experience!

Step 5: Add Chicken Stock
Gradually pour in 1 cup of chicken stock, stirring as you go. Bring the mixture to a gentle boil, then reduce the heat and let it simmer for 6-8 minutes. This is the time for the flavors of the Seafood Boil Sauce to meld and thicken, resulting in a velvety consistency.

Step 6: Finish with Acidity and Freshness
Remove the skillet from heat and stir in the juice of 1 lemon and ¼ cup of finely chopped fresh parsley. These ingredients will brighten your Seafood Boil Sauce and add a lovely burst of freshness. Taste and adjust seasoning if necessary, preparing your sauce for its grand debut!
