how to make in n out spread

Here’s a simple, copycat-style way to make In‑N‑Out–style spread at home, plus a few tweaks if you want to play with the flavor.

Quick Scoop

In‑N‑Out’s exact spread recipe isn’t public, but most close copycats use a base of mayonnaise, ketchup, sweet pickle relish, a bit of vinegar, and a touch of sugar for balance. Many home cooks also like to add a little yellow mustard, salt, and pepper to get closer to the signature taste.

Core Copycat Recipe

Ingredients (about 1 cup):

  • 1/2 cup mayonnaise
  • 3 tablespoons ketchup
  • 2 to 2 1/2 tablespoons sweet pickle relish
  • 1 to 1 1/2 teaspoons white vinegar
  • 1 to 2 teaspoons sugar
  • Optional but popular: 1 teaspoon yellow mustard, pinch of salt, pinch of black pepper

Instructions:

  1. Add mayo, ketchup, sweet pickle relish, vinegar, and sugar to a bowl.
  2. If using, add mustard, a small pinch of salt, and a pinch of black pepper.
  3. Whisk until completely smooth and uniform.
  4. Taste and adjust: more sugar for sweetness, more vinegar for tang, more relish for texture.
  5. Cover and chill at least 30–60 minutes; this helps the flavors meld and taste closer to the fast‑food original.
  1. Use on burgers, fries, or sandwiches.

Flavor Tweaks (If You Want to Experiment)

People online tweak the spread a bit depending on whether they want it sweeter, tangier, or “burger‑joint smokier.”

  • For more tang :
    • Add a bit more vinegar or a small extra squeeze of yellow mustard.
  • For more sweetness :
    • Increase sugar slightly or use a touch of honey instead of sugar.
  • For more texture :
    • Add an extra spoon of sweet relish.
  • For a lighter version:
    • Use light mayonnaise; some recipes specifically mention this works fine.

A common “internet standard” version many home cooks use looks like this:

  • 1/2 cup mayo, 3 tbsp ketchup, 2–2 1/2 tbsp sweet relish, 1 tsp yellow mustard, 1 tsp white vinegar, 1–2 tsp sugar, tiny pinch of salt and pepper.

How to Serve It

Most copycat recipes recommend chilling before serving and say it keeps well in the fridge.

  • Let it rest in the fridge at least 30 minutes, up to an hour, before using.
  • Store covered and refrigerated; many recipes say up to about 1–2 weeks is fine in a sealed container.
  • Use it as:
    • Burger spread (especially on griddled patties).
    • Sauce for “animal‑style” fries at home.
    • Dip for frozen fries, tater tots, or even roasted veggies.

Mini Forum‑Style Take

“Everyone swears they’ve cracked the exact In‑N‑Out formula, but the common thread is mayo + ketchup + sweet relish + a little acid and sweetness. Once you nail that balance, you’re in the right ballpark—even if it’s not pixel‑perfect to the original.”

TL;DR:
Mix mayo, ketchup, sweet pickle relish, a bit of vinegar, and a little sugar (plus optional yellow mustard), then chill—this gets you very close to classic In‑N‑Out‑style spread at home.
