This rich and flavorful Seafood Boil Sauce is loaded with garlic, butter, Cajun spices, and a touch of sweetness. It’s the perfect dipping sauce or topping for your favorite seafood boils!
Melt butter in a large skillet over medium heat. Add diced onion and cook for 5 minutes until softened.
Add diced garlic and cook for another 3 minutes, stirring frequently.
Stir in Cajun seasoning, Old Bay, onion powder, brown sugar, and red pepper flakes. Cook for 5 minutes.
Add chicken stock, stir well, and bring the sauce to a simmer. Simmer for 6–8 minutes to thicken slightly.
Remove from heat. Stir in lemon juice and parsley. Serve warm over seafood or as a dipping sauce.
Notes
Adjust the spice level by adding more red pepper flakes or a dash of hot sauce. For a thinner sauce, add extra chicken stock. Use unsalted butter if you prefer to control the saltiness more closely.
