Cajun BBQ Sauce
Homemade Cajun BBQ sauce with a kick, made with garlic, onions, ketchup, vinegar, and cayenne pepper. Perfect for burgers, hot dogs, ribs, or any grilled meat that needs a spicy Louisiana-style sauce.

Ingredients

4 cups servings
  • 4 garlic cloves minced
  • 2 cups chopped onions
  • 1/2 cup butter or margarine
  • 2 cups ketchup
  • 2 cups water
  • 1/2 cup vinegar
  • 1/2 cup sugar
  • 2 tsp salt
  • 1 tsp cayenne
  • 4 tsp Worcestershire Sauce
  • fresh chopped jalapeno (optional)

Step-by-Step Instructions

  1. Cook garlic and onion in the butter in a medium saucepan over medium heat until tender but not brown, about 8-10 minutes.
  2. Add remaining ingredients (ketchup, water, vinegar, sugar, salt, cayenne, and Worcestershire sauce) and bring to a simmer.
  3. Reduce heat to low and simmer 30 minutes, stirring occasionally, until sauce thickens slightly.
  4. Serve with grilled burgers and hot dogs. If you like hot, increase cayenne to 2 teaspoons and/or add two fresh chopped jalapenos.

Common Problems and Solutions

Q: Why is my sauce too thin?

A: Let it simmer longer to reduce and thicken, or start with tomato sauce instead of half the water for a thicker base.

Q: Can I make this ahead?

A: Yes! This sauce keeps well in the refrigerator for up to 2 weeks and the flavors actually improve after a day or two.

Tips and Techniques

For a smokier flavor, add 1-2 teaspoons of liquid smoke. You can also blend the finished sauce for a smoother consistency if you prefer it without onion chunks.
