Step 1

Heat oil in a large skillet over medium-high heat. Sauté onion and mushrooms in hot oil until onion begins to soften, about 5 minutes. Season vegetable mixture with salt and pepper and dried thyme; continue to sauté until onions and mushrooms brown, about 5 minutes more. Add a dash or two of Worcestershire sauce, if desired.

Step 2

Mix to combine the ingredients for the beef and form the patties. You can make 4 large patties, or I prefer to make 8 smaller ones.

Step 3

Cook burgers until they are firm, hot in the center, and just turning from pink to grey, 8 to 10 minutes per side for medium well.

Step 4

Whisk mayonnaise and Sriracha sauce together in a bowl until aioli is smooth. Spread aioli on each hamburger bun. Place a beef patty on the bottom bun, top with a slice of Monterey Jack cheese, one quarter of the onion-mushroom mixture, ¼ cup arugula, and cover burger with the top bun. Repeat with remaining burgers.
