450 g lean ground beef
60 g finely chopped onion
680 g jar prepared marinara sauce
4 tsp kosher salt, divided
3/4 tsp ground black pepper
1 tsp garlic powder
1 tsp Italian seasoning
340 g jumbo pasta shells
240 g ricotta cheese
50 g grated Parmesan cheese, divided
200 g shredded mozzarella cheese
2 tbsp finely chopped fresh parsley (optional)
Step 1
Preheat the oven to 190°C (375°F) and lightly grease a mini muffin pan.
Step 2
In a large pot, bring water to a boil over high heat.
Step 3
In a large deep skillet over medium-high heat, cook the ground beef until browned, about 5-7 minutes. Add the onion and cook until softened, about 3-4 minutes. Stir in the marinara sauce, 1 tsp salt, pepper, garlic powder, and Italian seasoning. Simmer for 20 minutes, stirring often.
Step 4
Add the remaining 3 tsp of salt and the pasta to the boiling water. Cook until tender, about 10-12 minutes. Drain, rinse with cold water, and drain well.
Step 5
Turn the pasta shells inside out and place 24 shells into the prepared muffin pan. Reserve any broken or remaining shells for another use.
Step 6
Fill each shell with about 2 tsp of ricotta and sprinkle 50 g of Parmesan cheese evenly over the ricotta. Top with about 1 tbsp of meat sauce, and then evenly sprinkle with mozzarella and the remaining Parmesan.
Step 7
Bake in the preheated oven until slightly golden around the edges and bubbly inside, about 15 minutes. Let stand for 10 minutes before serving. Sprinkle with parsley if desired.
