Seahawk Burger - cooking recipe

Ingredients

1 teaspoon vegetable oil
1 sweet onion (such as Walla Walla), sliced
8 ounces mushrooms, sliced
salt and ground black pepper to taste
1/2 cup Washington state red wine (such as a Merlot or Syrah)
4 (6 ounce) grass-fed ground beef patties
Seattle Aioli:
1/2 cup mayonnaise
1/2 teaspoon Sriracha sauce
1/2 shot brewed espresso (such as Starbucks(R))
4 whole grain or artisan hamburger buns (such as Macrina Bakery(R))
4 slices Monterey Jack cheese (such as Beecher's(R) Just Jack(R))
1 cup farmer's market arugula, or more to taste

Preparation

Heat oil in a large skillet over medium-high heat. Saute onion and mushrooms in hot oil until onion begins to soften, about 5 minutes. Season vegetable mixture with salt and pepper; continue to saute until onions and mushrooms brown, about 5 minutes more.
Pour the red wine into the pan and bring to a boil while scraping the browned bits of food off of the bottom of the pan with a wooden spoon. Cook and stir until wine evaporates, about 2 minutes; remove from heat.
Preheat an outdoor grill for medium-high heat and lightly oil the grate.
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. An instant-read thermometer inserted into the center should read 150 degrees F (65 degrees C).
Whisk mayonnaise, Sriracha sauce, and espresso 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, 1/4 the onion-mushroom mixture, 1/4 cup arugula, and cover burger with the top bun. Repeat with remaining burgers.
