Tips for In and Out Burger Sauce Recipe:

  • Make Ahead – We think the sauce taste best when it has set in the refrigerator for a few hours and even overnight. It gives time for all the ingredients to really marinate together.
  • Use it as a Marinate – This sauce would be great to marinate your chicken breast or chicken thighs in. Just place chicken in a zip lock bag and spoon in some sauce. Let it marinate overnight and then grill or bake your chicken.
  • Burger Bowl – I like to eat burger with no bun and make a burger bowl. I line a bowl with lettuce, dice up the burger and drizzle this sauce over the top. It gives it amazing flavor and I know exactly what is in the sauce.
