In n Out Sauce Recipe
We sadly do not live in an area that has In n Out restaurants. The closest one to us is probably a 6-7 hour drive from our house.
A bit too far to drive for dinner not that we haven't thought about it a few times. LOL! Thankfully we travel fairly frequently and get the opportunity to do road trips like our California Big Trees road trip we did last year.
This year we took a road trip from Spokane all the way to El Paso and back visiting epic national parks for my husband's Park Ranger John website. It was such an amazing trip and took us to cities with In n Out Burgers which was a total bonus.
I knew that I wanted to make an In n Out Sauce recipe so we could enjoy this great sauce at home. During our Southwest National Park Road trip I brought with us multiple plastic containers so I could bring home packets of In n Out sauce from the restaurants. I stashed them in our cooler and kept them cold the entire way home through a heatwave.
Once we were home I started working on making sure our recipe tasted just like the restaurant recipe. I love having the real sauce in the house so we can compare flavors as I add and change the recipe until we get it just right.
We went through quite a few Air Fryer French Fries making sure this recipe was just right. It is really cool knowing that IN-N-OUT Burgers has been using the same sauce since 1948.
This burger sauce is epic and so easy to make! Not quite a secret sauce or special sauce it is one of the most famous west coast restaurant sauces we can find at a fast food restaurant.
