Onion Straws
- 1/2 cup very thinly sliced onion
- 1/4 cup soy flour
- 1/2 teaspoon kosher salt
- 1/8 teaspoon freshly ground black pepper
- 1/8 teaspoon garlic powder
Casserole
- 1 pound green beans, ends trimmed
- 1 tablespoon vegetable or canola oil
- 1/2 cup thinly sliced onion
- 8 ounces cremini mushrooms, rinsed and sliced
- 1 1/2 teaspoons kosher salt
- 1/8 teaspoon garlic powder
- 1/8 teaspoon freshly ground black pepper
- 1/2 cup no-sugar, low-sodium chicken broth
- 1 teaspoon chopped fresh thyme leaves, plus a few sprigs for garnish
- 1/2 cup sour cream
Special equipment:
- 10-inch glass pie pan
Instructions
- Preheat oven to 350F.
- Prepare the Onion Straws: Mix all ingredients in a small bowl, toss to coat evenly, and spread in a single layer on a baking sheet. Set aside.
- Prepare the Casserole: Bring a small pot of salted water to a boil. Cook green beans until tender-crisp, about 5 minutes. Drain, cool in ice water, drain again, and place in a bowl.
- Warm oil in a large skillet over medium-high heat. Add onion, mushrooms, salt, garlic powder, and pepper; saut 2 minutes. Add broth and thyme; cook until liquid reduces, 3-4 minutes. Combine with green beans and stir in sour cream.
- Transfer mixture to glass pie pan. Place casserole and onion straws on separate oven racks. Bake until straws are deeply browned and crisp, 15-17 minutes. Top casserole with straws and garnish with thyme sprigs.
