Creating Seafood Stuffed Potatoes is straightforward if you follow these steps:

1. Preheat Oven: Begin by preheating your oven to 400°F (200°C).
2. Prepare Potatoes: Scrub the potatoes under running water. Pat them dry and pierce each potato several times with a fork.
3. Oil and Season: Rub the potatoes with olive oil and season with salt and pepper. Place them directly onto the oven rack.
4. Bake Potatoes: Bake the potatoes for 45-50 minutes or until they are tender and cooked through.
5. Make Filling: While the potatoes are baking, prepare the filling. In a large bowl, mix together shrimp, crab meat, cream cheese, sour cream, cheddar cheese, lemon juice, garlic powder, and onion powder.
6. Scoop Potatoes: Once the potatoes are done, carefully remove them from the oven and allow them to cool slightly. Cut the tops off and scoop out most of the insides, adding the potato flesh to the filling mixture.
7. Combine Mixtures: Stir well to ensure everything is well combined. Adjust seasoning as necessary.
8. Stuff Potatoes: Generously fill each potato skin with the seafood mixture, pressing down to compact the filling.
9. Return to Oven: Place the stuffed potatoes back in the oven for another 10-15 minutes, or until heated through and the tops are slightly golden.
10. Garnish: Remove from the oven, allow to cool slightly, and then garnish with fresh parsley or chives before serving.

These steps will ensure that your Seafood Stuffed Potatoes turn out perfectly every time.
