First, preheat the oven to 350 degrees F and bring a large pot of water to a boil.
Next, boil the pasta for 10 minutes, stirring occasionally. Strain and return the pasta to the empty pot, removing it from the heat.
Add the pasta sauce to the pot and stir to coat the pasta well. Then add about two-thirds of the mozzarella cheese and stir well to combine.
Next, lightly grease a large baking dish. Transfer the contents of the pot to the baking dish, spreading the pasta out evenly. Top with the remaining shredded cheese.
Finally, loosely cover the baking dish with aluminum foil and bake for 30 minutes. Serve hot, or store in an airtight container in the fridge for up to 5 days.
Notes
Pasta sauce: Use your favorite kind of jarred pasta sauce, or use a homemade one if you prefer! We recommend picking something extra flavorful like a tomato & basil or roasted garlic since it'll be the main source of flavor in this dish.Serving suggestion: We recommend serving this baked penne pasta with garlic bread and a side salad for a well-rounded Italian meal.Storing & meal prep: Baked penne is the perfect meal to prep for the week - it'll last up to 5 days in the fridge when stored in an airtight container. Some weeks we like to make a batch on Sunday night, then portion it out for easy grab-n-go lunches.Reheating leftovers: Reheat single servings in the microwave for about 2 minutes, stirring halfway through. Or, reheat a larger batch in the oven at 350 degrees F for about 10 to 15 minutes, or until warmed through.
