My parents recently ditched me and the East Coast and moved to Southern California where it’s perfect weather 89% of the year. I don’t blame them at all. First, it’s much closer to Asia (Taiwan, specifically), and second they’re retired and who doesn’t want to retire in a state where the humidity is low and sunshine is abundant? Most importantly, California and the West Coast sure do have some pretty legit burger joints that we have yet to get over here. I remember when Shake Shack first came over, then Habit Burger. We are still waiting on In n Out.

What is a California Burger?

Well, the beef patty itself is pretty standard as a beef patty on a burger goes (however – I discovered this hack for burger patties that I’m pretty sure I will never make a burger without again. Keep reading…) but the ‘California’ part of the burger is more about the toppings on the burger than anything else.

As we all know, California is tends to have fresh ingredients all year long and the lettuce, tomatoes, onions on top of this California Burger are as fresh as can be! However, most notably, the avocado is what really gives this burger its name. I’m not sure how it was coined that when you throw an avocado on something, it automatically becomes Californian, but hey – I’m here for it.

How To Make a California Burger

Here is a general overview of the steps involved to make this sunny and bright California burger. Be sure to scroll to the bottom of this post for the full recipe.

Mix the burger meat and seasonings. In a large bowl, mix together ground beef, onion dip seasoning mix, grated onion, salt, and pepper with your hands. Do not overmix!

Form the burger patties. Form even burger patties with your hands, about 5 ounces each. Flatten to desired thickness. Set aside on a baking sheet or plate.

Pop in the freezer. As you’re preparing the other toppings, pop the burger patties in the freezer. Since you were working with the meat with your hands, the freezer will quickly help the meat firm up again so it won’t fall apart on you since there’s no binder.

Cook the burgers. Once everything is prepped, heat outdoor grill on high or cast iron skillet on the stovetop. Cook the burger patties to your desired doneness.

Add the toppings. Toast up brioche buns then add all the toppings to your California burger!

Recipe Tips, Substitutions, and Variations

  • Don’t overmix the beef mixture. Overmixing will cause the burger to be dense and tough which will result in a less than stellar burger. Mix until ingredients are just combined. Remember, you still have to form the patties so less time mixing it will help the entire mixture not be overmixed in the end.
  • Why grate the onion? I love grating onion when I’m making burgers because sometimes the diced onions don’t allow the beef to bind together well and it makes it fall apart. The grated onions also are so fine that it is able to be evenly distributed throughout all the burger meat.
  • Use another ground protein. For a leaner option, ground turkey and ground chicken would be a great substitute for the ground beef.
  • Make it spicy. Adding a little bit of cayenne pepper would kick the heat up but pickled or regular jalapeño slices on top would be a great addition too!
  • Go bunless. If you’re watching carbs, use the green leaf lettuce to make this into a wrap!
  • Try not to press down on the patty while cooking. You’re essentially squeezing out all the juices that keep the burger moist! Resist the urge to press down on it. Just flip and let it do its thing.
  • BYOB. Everyone loves options so laying out all the topping possibilities for this burger would give everyone different ways to build their own burger.
  • Grill it, air fry it, sear it. Whichever method of cooking works for you, this burger recipe isn’t picky!

Storage and Reheating Instructions

There are several ways to store and reheat these burger patties! It depends on your method so here are some options for you.

Prepping ahead of time: If you’re making the burger patties ahead of time to freeze, form the burger patties then wrap them tightly in plastic wrap and place into a freezer-safe bag in the freezer for up to 3 months. You can cook them directly on your outdoor grill from frozen.

Refrigerator: For already cooked burger patties, store in an airtight container in the refrigerator for up to three days. To reheat, you may reheat on the stovetop or if you’re going to use a microwave, cover with a damp paper towel to keep some of the moisture.
