Yield 6 servings

Number Of Ingredients 9

1 Tablespoon grapeseed oil, plus more for frying
1 pound petite green beans, trimmed
1 Tablespoon olive oil
1 1/2 cup slices small button mushrooms
1 1/2 cups milk
1 Tablespoon tapioca starch
1/2 teaspoon salt
1/8 teaspoon black pepper
2 onions, thinly sliced

Steps:

Preheat oven to 350 degrees F. Grease a 9 inch baking dish with 1 Tablespoon of grapeseed oil. Bring a large saucepan of water to a boil over high heat. Add the green beans and cook until bright green, about 7 minutes. Drain and set aside. Heat the olive oil in a medium skillet over medium-high heat. Add the mushrooms and cook until golden, about 4 minutes. Whisk in the milk, tapioca starch, salt, and pepper and cook until thickened, about 7 minutes. Add the green beans and cook until the beans are completely tender, about 7 minutes. Let the mixture cool for 5 minutes, and then transfer to a serving dish. Bake for 15 to 20 minutes. Meanwhile, spread the onion slices on several layers of paper towels and pat dry. Pour about 1/4 inch of grapeseed oil into a small saute pan and place it over medium-high heat. Working in batches, fry the onions until golden brown and crispy, about 2 minutes. Transfer to a paper towel-lined plate to drain. Sprinkle over the green bean mixture just before serving.
