Bring a large pot of salted water to a boil. Cook the jumbo shells according to package directions until al dente. Drain and let them cool for a few minutes so they're easier to handle when stuffing.

In a large oven-safe skillet over medium-high heat, brown the ground beef with chopped onion. Season with salt, pepper, paprika, and Italian seasoning. Once browned, drain excess grease and add minced garlic. Cook for 30 seconds, then stir in marinara sauce and simmer on low.

In a mixing bowl, combine ricotta cheese, egg, Parmesan cheese, garlic powder, and dried parsley. Mix well until smooth and creamy. This filling will stuff about 21 shells.

Using a spoon, carefully fill each cooled shell with 1½ to 2 spoonfuls of the ricotta mixture. Don't overfill them or they'll be difficult to handle and may break.

Preheat oven to 400°F. Place the stuffed shells in the skillet with the meat sauce, pressing them gently into the sauce. If using a regular skillet, transfer everything to a greased 9x13 baking dish. Top with mozzarella cheese.

Bake uncovered for 25 minutes until the cheese is melted and edges are slightly crispy. Cover with foil if you prefer softer edges. Let cool for 5 minutes, garnish with dried parsley, and serve hot.
