Preheat oven to 375 F
Spray a casserole dish or pan with deep edges with nonstick cooking spray
After green beans have been thoroughly washed and the ends removed, bundle them into 4-5 pieces and wrap a piece of bacon around each bundle
Place each bundle in the dish with the wrapped side of the bacon face down to prevent it from unraveling
In a small pot, melt butter over low heat and add in brown sugar and stir until melted
Sprinkle salt, pepper, garlic powder and Cajun seasonings on top of each bundle
Pour the butter and brown sugar mixture over the bundles and bake in oven for 45 minutes, or until the bacon is crisp
Serve immediately & enjoy!
