Wild MushroomCheddar Burger

• 2 tablespoons olive oil
• 1 tablespoon unsalted butter
• 12 ounces assorted mushrooms (such as cremini, lobster, chanterelles, and stemmed shiitakes), chopped
• 1 small shallot, finely diced
• Kosher salt and freshly ground black pepper
• 1 tablespoon chopped fresh thyme leaves
• 2 tablespoons chopped fresh flat-leaf parsley leaves
• 1 1/2 pounds ground chuck (80 percent lean) or ground turkey (90 percent lean)
• 1 1/2 tablespoons canola oil
• 4 slices sharp cheddar cheese
• 4 hamburger buns, split; toasted (see page 15), if desired
• Chipotle Ketchup (page 112; optional)

1. Heat the olive oil and butter in a large saute pan over high heat until almost smoking.
2. Add the mushrooms and cook, stirring occasionally, until soft, about 5 minutes.
3. Add the shallot, season with salt and pepper, and cook until the mushrooms are golden brown, about 5 minutes.
4. Stir in the thyme and parsley and transfer to a bowl.
5. Divide the meat into 4 equal portions (about 6 ounces each).
6. Form each portion loosely into a 3/4-inch-thick burger and make a deep depression in the center with your thumb.
7. Season both sides of each burger with salt and pepper.
8. Cook the burgers, using the canola oil (see page 16) and topping each one with a slice of cheese and a basting cover during the last minute of cooking (see page 21).
9. Place the burgers on the bun bottoms and top each burger with chipotle ketchup, if using, and a large spoonful of the mushrooms.
10. Cover with the bun tops and serve immediately.
