Ingredients

  • 4 sticks Butter unsalted (3 sticks optional read post and see notes below)
  • ¼ cup Olive oil
  • 1 whole Onion diced
  • 3 tablespoons Garlic diced
  • 1 Lemon juiced
  • 4 cups Chicken or Vegetable broth or water
  • 3 tablespoons Old Bay seasoning
  • 3 tablespoons Paprika
  • 2 tablespoons Chili powder
  • 1 tablespoon Cajun seasoning
  • 1 tablespoon Cayenne pepper
  • 1 tablespoon Red pepper flakes
  • 1 tablespoon Lemon pepper seasoning (optional depending on fresh lemon juice)
  • 1-2 dashes Tobasco sauce
  • 2 tablespoons Sweet chili sauce optional

Instructions

  • Melt one stick of butter and olive oil in a skillet on medium heat. Add the sliced or chopped onions and sauté them until they become translucent, about 5-7 minutes.
  • Stir in the Garlic and saute for 30 seconds to one minute, be sure to stir constantly so the garlic doesn't burn. Add juice of the lemon, and all of the seasonings. Adjust cayenne and red pepper to your level of desired spiciness.
  • If using additional butter, add the additional sticks now (see notes above about healthier option).
  • Pour in the chicken broth, vegetable broth, or water now (choose either or, not all three). Simmer the sauce until the butter is melted and the sauce reduces a bit, about 10 minutes.
  • Pour over your favorite seafood and/or reserve some for dipping.

Notes

One stick of butter is necessary, however do not use the remaining 3 sticks if it's not desired.
Add chicken broth or water to cut the fat ratio from the butter. Allow the sauce to simmer for at least 10 minutes so that it is not too thin/runny.
