1. Prepare the Crust:

1. Preheat oven to 375°F (190°C). Peel onions and cut off tops and bottoms to create flat surfaces.
2. Carefully hollow out each onion, leaving about 1/2-inch thick outer layers. Reserve removed onion for other use.
3. Stuff each hollowed onion with cheddar cheese cubes, packing tightly.
4. Wrap each stuffed onion with 3 slices of bacon, securing with toothpicks if needed.
5. Mix garlic powder, smoked paprika, and black pepper. Rub olive oil over bacon-wrapped onions, then sprinkle with seasoning mix.
6. Place onions on baking sheet and bake for 25-30 minutes until bacon is crispy and cheese is melted.
7. Let cool for 5 minutes before serving.
