Preheat your oven to 190°C (375°F) and bring a large pot of salted water to a boil.
Cook the pasta shells in the boiling water until just al dente, about 8 minutes. Drain and set aside to cool slightly.
In a mixing bowl, combine ricotta, shredded mozzarella, Parmesan, and your minced or roasted garlic. Sprinkle in smoked paprika and season with salt and pepper, then mix until smooth and creamy.
Using a spoon or piping bag, carefully stuff each shell with the cheese mixture, pressing gently to fill completely without overstuffing.
Arrange the stuffed shells in a baking dish and pour marinara sauce over the top, ensuring each shell is well coated. Sprinkle extra cheese on top for a golden finish.
Bake in the preheated oven for 25-30 minutes, until the sauce is bubbling and the cheese on top is golden and slightly crispy at the edges.
Remove from the oven and let the shells rest for 5 minutes to settle the cheese before serving.
