In a medium skillet over medium heat, cook chopped bacon until crisp, about 6 to 8 minutes.
Transfer bacon to a paper towel–lined plate and discard all but 1 tablespoon of the bacon grease.
Add butter, melt, then stir in diced onion and sauté until tender and translucent, about 3 minutes.
Make Sauce & Cook Beans
Stir in brown sugar and bourbon; bring to a simmer and cook until the sugar dissolves and the bourbon reduces by half, about 2 minutes.
Add green beans, water, salt, pepper, garlic powder, and red pepper flakes; stir to coat well.
Cover and cook until beans are tender yet retain a slight snap, about 10 minutes, stirring halfway through.
Uncover, stir in crispy bacon and lemon zest, then serve immediately.
Notes
Testing Note #1: Trimming beans in uniform pieces shaved off prep time and ensured even cooking.Testing Note #2: If beans brown too quickly, lower the heat and add a splash more water to prevent sticking.Testing Note #3: Let the dish cool completely before sealing in an airtight container to keep the beans firm.
