Preheat oven to 400F. Place bacon on a parchment lined baking sheet and bake for 15-20 minutes or until desired crispiness is reached. Chop and set aside. Add the onion to medium sized skillet with olive oil and cook for 2-3 minutes, until softened. Add the green beans, chicken stock, 1 teaspoon granulated garlic, and 1/2 teaspoon kosher salt. Stir and cover. Reduce the heat to medium-low and simmer for 30 minutes. After 30 minutes, sprinkle the green beans with 1/2 teaspoon granulated garlic. Arrange the potatoes over the green beans. Dot with butter and sprinkle with the remaining salt and pepper. Cover and simmer for 25-30 minutes, until the potatoes are fork tender. Stir gently and transfer to a serving dish. Sprinkle the bacon over the green beans and potatoes. Enjoy!
