Preheat your oven to 400°F (200°C).
Prepare the green beans by trimming the ends.
In a bowl, toss the green beans with olive oil, garlic powder, black pepper, and salt.
Take a bundle of 4-5 green beans and wrap a slice of bacon around them, securing with a toothpick if necessary.
Place the wrapped bundles on a baking sheet lined with parchment paper.
Sprinkle paprika on top of the bundles if using, just before baking.
Bake in the preheated oven for 20-25 minutes, or until the bacon is crispy and the green beans are tender.
Remove from the oven and let cool slightly before serving.
