Bring a large pot of salted water to a boil. Add the trimmed green beans and cook for about 3 to 4 minutes until they are bright green and slightly tender. Immediately transfer them to a bowl of ice water to stop the cooking process, then drain and pat them completely dry with a paper towel.
In a small bowl, whisk together the melted butter, brown sugar, garlic powder, and onion powder. Add a pinch of salt and pepper to the mixture. This savory glaze will help the turkey bacon caramelize and add a depth of flavor to the beans as they roast in the oven.
Preheat your oven to 400 degrees Fahrenheit. Take about 6 to 8 green beans and gather them into a neat bunch. Wrap one slice of turkey bacon tightly around the center of the bundle. Place the bundle on a baking sheet lined with parchment paper, ensuring the seam of the turkey bacon is facing down to keep it secure.
Use a pastry brush to coat each bundle generously with the prepared butter and brown sugar glaze. Place the baking sheet in the oven and bake for 20 minutes. At this point, the turkey bacon should be starting to brown and the green beans should be tender.
Remove the tray from the oven and sprinkle the shredded cheddar cheese over the center of each bundle. Return the tray to the oven for an additional 3 to 5 minutes, or until the cheese is melted and bubbling. Serve immediately while hot.
