Mississippi Sin Dip Recipe: Creamy Roast Beef Party Dip

Mississippi Sin Dip is a creamy, savory party dip made with ranch seasoning, au jus mix, sour cream, mayonnaise, and pepperoncini for a bold, tangy bite. This easy cold dip comes together in minutes and improves after chilling, making it perfect for game day, holidays, or last-minute gatherings. Serve with crackers, chips, or fresh vegetables — it always disappears fast.

This dip is usually the first thing to go at gatherings, and my family asks for it every time. It pairs well with other cold appetizers like an everything bagel cheese ball, homemade tortilla chips, and a simple sweet dip if you want a contrasting option.

Ingredient Notes

Ingredients for Mississippi Sin Dip including ranch seasoning mix, au jus gravy mix, sour cream, mayonnaise, pepperoncini peppers, and pepperoncini juice

Complete ingredient quantities and the printable recipe are located in the recipe card below.

  • Sour cream: full-fat yields the creamiest texture. You can substitute full-fat Greek yogurt if preferred.
  • Pepperoncini peppers: use jarred or canned, finely chopped. Reserve some of the juice to add tang. Banana peppers can be used as a milder substitute.

Helpful Tips

  • Finely chop the pepperoncini so they distribute evenly throughout the dip.
  • Add pepperoncini juice gradually — start small and increase to taste for more tang.
  • Chill the dip for at least 30 minutes for the best flavor.
  • Give the dip a quick stir just before serving to maintain a smooth texture.

Storage

Store the dip in an airtight container in the refrigerator for up to 4 days. Freezing is not recommended, since the sour cream and mayonnaise base can separate.

Variations and Add-ins

  • Stir in shredded cheddar or Colby Jack for extra richness.
  • Add finely chopped cooked bacon for a smoky, savory note.
  • A spoonful of cream cheese makes the dip thicker and easier to scoop.
  • A pinch of black pepper or garlic powder adds depth of flavor.
