Easy Baked Mostaccioli

Step 1
Preheat the oven to 350 degrees F (175 degrees C). Grease a 9×13-inch baking dish with cooking spray.

Step 2
Bring a large pot of lightly salted water to a boil. Cook mostaccioli in the boiling water, stirring occasionally, until tender yet firm to the bite, 8 to 10 minutes. Drain.

Step 3
Meanwhile, heat a nonstick pan over medium-high heat. Cook and stir ground beef until browned and crumbly, 5 to 10 minutes. Remove from the heat. Drain and discard grease. Add spaghetti sauce to the pan and mix with the beef.

Step 4
Transfer beef mixture to the prepared baking dish. Spread evenly over the bottom and layer cooked pasta over top. Sprinkle with mozzarella and Parmesan cheeses. Cover with foil.

Step 5
Bake in the preheated oven for 40 minutes. Remove foil and continue to bake until cheese is melted and lightly browned, about 10 more minutes.
