Ingredients
Method
- Heat oven to 375°F (190°C). In a large skillet over medium-high heat, cook the beef until browned, about 6 minutes. Add onion and garlic and cook 3 minutes more. Drain fat and let cool.
- In a large bowl, combine the cooled beef mixture, ricotta, 1 cup mozzarella, Parmesan, egg, spinach (if using), salt, and pepper. Stir until evenly mixed.
- Spoon 1 cup marinara into a 9x13-inch baking dish. Fill each uncooked manicotti shell with the meat mixture, packing it in firmly, and lay them in a single layer in the dish.
- Pour the remaining 2 cups marinara over the shells, nudging sauce between them. Sprinkle the reserved 1/2 cup mozzarella on top.
- Cover with foil and bake 30 minutes. Remove foil and bake another 5 to 10 minutes until the cheese is melted and lightly browned. Let rest 5 minutes, then top with parsley or basil and serve hot.
Notes
Let the manicotti rest for 5 minutes before you scoop the first serving. That short pause lets the filling set up a little, so the dish holds its shape on the plate instead of sliding apart.
