One thing you may not know about me is that I’m actually a California girl. While Californian’s love the sun and the beach, there is another thing that I feel many Californians feel very passionate about: In-N-Out Burger.

When I first moved the Texas, the In-N-Out vs Whataburger debate was a constant point of conversation at my household. While whataburger does win on the vast menu options, In-N-Out takes the cake on the most delicious burger sauce recipe.

Naturally, I had to take a piece of my home and recreate it in my own kitchen so here you have my own copycat In-N-Out burger sauce recipe. It tastes so similar to the classic sauce and will take your homemade burgers to a level that mustard and ketchup simply cannot!

Ketchup: I prefer one that has no added sugar because we will be adding our own sugar.
Dill relish: If you prefer a sweeter sauce, you could choose sweet relish.
Sugar: Add this is small increments and to taste!

That’s all you’ll need to make your burgers feel fancy and customized!

The process:

This sauce will be ready to enjoy in just two simple steps:

LTN Tip: Be sure to add your ingredients, especially the sugar, in small increments. If you used a ketchup that has added sugar in it or choose to include a sweet relish, you may want to add a bit less sugar so that your sauce does not get too sweet. Always add to taste.

Recipe FAQ:

Can I make this recipe lower in calorie?
1. Absolutely! If you make it as written, the low fat mayo significantly cuts down on calories that you would see in other traditional burger sauce recipes. If you want a lower calorie and higher protein burger sauce, use blended cottage cheese instead of mayonnaise.
How should I store the sauce?
1. I store mine in a sealed, glass container in the refrigerator. Then, I give it a good stir when I am ready to eat.
How long will the leftovers stay good?
1. Per the USDA, you can refrigerate the leftovers for 3 to 4 days and enjoy throughout the week making this a great dip to store in the refrigerator. As always, you should also use your best judgment when assessing leftovers and give it a stir before you enjoy it again.
