Creating Southern-Style Seafood Stuffed Potatoes is simple when you follow these easy steps:

1. Preheat Oven: Preheat your oven to 400°F (200°C).
2. Prepare the Potatoes: Scrub the russet potatoes thoroughly and pierce them with a fork several times. Place them on a baking sheet and drizzle with olive oil. Sprinkle with salt.
3. Bake the Potatoes: Bake in the preheated oven for 45-50 minutes, or until tender when pierced with a fork.
4. Make the Filling: While the potatoes are baking, combine the chopped shrimp, crab meat, cream cheese, sour cream, ½ cup of the shredded cheddar cheese, green onions, parsley, Old Bay seasoning, garlic powder, salt, and pepper in a mixing bowl. Mix until well combined.
5. Scoop the Potatoes: Once the potatoes are done baking, remove them from the oven. Allow them to cool slightly. Cut each potato in half and scoop out a portion of the flesh, leaving enough to create a sturdy shell.
6. Combine with Filling: Add the scooped-out potato flesh into the seafood mixture. Mix until well blended.
7. Stuff the Potatoes: Spoon the seafood mixture back into the potato halves, packing them generously.
8. Add Cheese: Top each stuffed potato with the remaining ½ cup of shredded cheddar cheese.
9. Final Bake: Place the stuffed potatoes back in the oven and bake for an additional 15-20 minutes, or until the cheese is melted and bubbly.
10. Garnish: Remove from the oven and garnish with additional green onions and parsley if desired.
