Add the oil to a large non-stick skillet...

Add the oil to a large non-stick skillet and heat to medium. Add the onions and cook, stirring occasionally, until onions begin to brown on the edges, about 15 minutes. Reduce the heat to medium-low and continue cooking, stirring occasionally, until onions are dark brown and caramelized, about 40 minutes. Add a small amount of water twice throughout the cooking process to deglaze the pan when the onions begin sticking.

Once the onions are almost fully caramelized, add the mushrooms. Continue cooking until onions are a deep brown color and mushrooms have leached mush of their liquid, have softened, and have a golden-brown sear on them.

While the onions are caramelizing, make the pesto...

While the onions are caramelizing, make the pesto sauce and prepare the burgers. Add the basil, walnuts, and sea salt to a food processor and pulse until chopped. Leave the food processor on while streaming the oil through the top. Taste for flavor and add more sea salt or oil as desired. Set aside until ready to use.

Add the ground meat to a mixing bowl...

Add the ground meat to a mixing bowl along with the sea salt, onion powder, and garlic powder. Mix well with your hands. Form 4 to 6 burger patties (according to your size preference).

Add 1 to 2 tablespoons of avocado oil...

Add 1 to 2 tablespoons of avocado oil (or cooking oil of choice) to a large cast iron skillet and heat to medium-high. Once the skillet is fully hot, carefully place the burger patties on the surface. Cook until deep brown char marks appear, about 3 to 5 minutes. Carefully flip and continue cooking to desired doneness, another 2-3 minutes for medium-rare, 5 minutes for medium, and 7 to 8 minutes for well-done.

Toast your burger buns (if desired), then add...

Toast your burger buns (if desired), then add sauteed kale (or green of choice), a burger patty, pesto sauce, and caramelized onions and mushrooms. Sink your teeth in, and enjoy.

Caramelized Onion Burger with Arugula

1lb 85% lean ground beef*

onion

salt

tsp black pepper

tsp black garlic (I had some on hand

red pepper flakes

paprika

tbs worchestershire sauce

yellow onion, thinly sliced

tsp coconut sugar sugar

ghee butter

Arugula

Brioche Bun or Lettuce Wrapped

Provolone Cheese

 MIX IT -  In a large bowl, combine beef, onion, spices, and worchestershire sauce. 

Form It

- Form into 4 evenly sized patties and store in the fridge while you make the caramelized onions. 

SAUTE

- Heat a high rimmed skillet over medium high heat. Add ghee. Once it starts simmering, add the onion. Stir frequently to prevent burning. After the onions have softened (about 3-5 minutes), add the sugar. The sugar helps the caramelization process move faster. Keep sauteeing until all onions are a dark brown color. (about an additional 7-10 minutes). Discard to a paper towel lined plate and set aside.

Cook

- In the same skillet, add the burger patties. Cook about 2 minutes per side. About 1 minute before the burgers finish cooking, add the cheese (if using). 

Steam the cheese

- To get super yummy gooey cheese, put the lid on the skillet for 1 minute. And be prepared to be WOWED by the steamed provolone cheese 🤤

ASSEMBLE - 

Build your perfect french onion style burger. To the bun add the burger, onions, and arugula. So simple yet so good! 

Boom! This recipe is delicious and super easy. The burgers drop, literally, with flavor. The sautéd onions and arugula add just the right touch. Another winner, Amanda!

And again, if I can make this, anyone can.
