Prepare the Peppers

1. Preheat the Oven: Preheat your oven to 375°F (190°C). Grease a baking dish large enough to hold your bell peppers.
2. Prepare the Peppers: Cut the tops off the bell peppers and remove the seeds and membranes. Place the peppers upright in the prepared baking dish.

Make the Filling

1. Cook the Shrimp: In a medium skillet, heat olive oil over medium heat. Add the shrimp and cook for 2-3 minutes per side, until pink and cooked through. Remove from the pan and chop into small pieces.
2. Sauté the Aromatics: In the same skillet, add the chopped onion and garlic. Sauté for 2-3 minutes until softened and fragrant.
3. Prepare the Filling: In a large bowl, combine the cooked shrimp, crab meat, sautéed onion and garlic, breadcrumbs, cream cheese, Parmesan cheese, parsley, Old Bay seasoning, paprika, salt, and pepper. Mix well to combine.

Stuff the Peppers

1. Fill the Peppers: Spoon the seafood mixture into each bell pepper, pressing down gently to pack the filling.
2. Top with Cheese (Optional): Sprinkle shredded mozzarella cheese on top of each stuffed pepper for a cheesy finish.
3. Bake: Cover the baking dish with aluminum foil and bake for 30 minutes. Remove the foil and bake for an additional 10 minutes, or until the peppers are tender and the cheese is golden and bubbly.

Finish and Serve

1. Cool Slightly: Let the stuffed peppers rest for a few minutes before serving.
2. Garnish and Serve: Garnish with fresh parsley and serve hot.
