This copycat In N Out Burger recipe may just be better than the real thing! Give it a try and see!
I grew up with a mother who was born and bred in California and thus a huge fan of In-N-Out Burgers. I on the other hand was born in California but raised in Wisconsin, a state with no In-N-Out within a 1,000 miles or more. It wasn’t actually until I was an adult myself on a trip to California that I experienced my first In-N-Out burger. From that time forward anytime I am in a state with an In-N-Out, my internal hamburger radar manages to find one.
Given the fact that I live in Oregon I was pretty excited when I ran across a copycat In N Out burger recipe. Now, I know there are those of you out there that don’t think In-N- Out is so great and I respect that but for you fellow In-N-Out fans, today’s post is for you I have no idea if this is how they really make their burgers but it is a good burger. In fact, my husband thought it was better than In-N-Out.
In N Out Burger Sauce
One of the most important parts of an In N Out burger is the In n Out Sauce! It is so easy to make and so delicious that you will want to add it to all of your bugers! For the secret sauce, you combine simple hamburger condiments, mayo, ketchup, and pickle relish. And then you add the secret ingredient, and a little white vinegar.
It looks and tastes just like the real thing!
How to caramelize onions
Next, I made the caramelized onions that go on top. Finely chop your onion and then cook them in vegetable oil. Cover them and allow them to cook slow for about 30 minutes until they are golden and soft. Watch your heat and don’t let them burn. Uncover them once they have started to brown and caramelize and cook for about 5 more minutes. Add in 1/2 C water and simmer until the water evaporates. These can be made ahead of time and set aside.
How to Make a Copycat In N Out Burger
After you have your In-N-Out Sauce made and your onions carmalized, it is time to start on the other ingredients to make the perfect Copycat In-N-Out burger!
Firs, you will want to toast your buns. This is one of the things I love about an In-N- Out Burger! Heat up your electric griddle and brush it lightly with some vegetable oil. Place your buns split side down on the griddle and toast until golden brown.
Set these aside and it’s time to cook the burgers. The recipe calls for ground beef chuck (at least 60% lean) This is different than regular ground beef. Then make your patties. I made my patties thicker than In-N-Out, but you can make them thiner for a more authentic experience. Add a sprinkle of salt and pepper to both sides.
Place your patties on your hot griddle (these hamburgers are not put on a BBQ grill) Cook for 3-5 minutes, depending on the thickness of your patty and your desired doneness. Spread the patty with 1 1/2 tsp of mustard on the uncooked side and then flip.
Top the cooked side with a slice of cheese. In-N-Out uses American cheese but I used a nice slice of cheddar. Again, make it with the cheese you love, or use American for an authentic In-N-Out burger!
Cook to your desired doneness. Then spread some of the burger sauce on your bun, add lettuce, tomato, the hamburger patty and caramelized onions.
For a more complete experience you can even put it into a little paper container and pretend you are in California eating the real thing! But checkered paper or not, it will taste like you are there!
