Method
Prepare the casserole
- Heat the oven to 375°F and rub the olive oil over the bottom and sides of a 9x13-inch baking dish.
Cook the pasta and sauce
- Bring the water to a boil in a 6-quart pot, add the kosher salt and penne, and cook 2 minutes less than the package directions; drain.
- Return the penne to the pot and stir in the marinara sauce.
Make the cheese mixture
- In a medium bowl, stir together the ricotta, egg, Parmesan, and black pepper until combined.
Assemble and bake
- Spread half the sauced penne in the prepared dish, spoon the ricotta mixture evenly over it, and sprinkle with 1 cup of the mozzarella.
- Spread the remaining penne over the cheese layer and top with the remaining 1 cup mozzarella; bake uncovered for 25 to 30 minutes, until bubbling at the edges and the center reaches 160°F.
Rest the casserole
- Let the casserole rest for 10 minutes before serving.
Notes
For a firm pasta texture, cook the penne 2 minutes less than the package directions before baking. Refrigerate leftovers for 3 to 4 days; freezing is suitable. Gluten-free penne can be used as a dietary swap.
