Here's a basic and quick recipe for a vegetarian oven-baked pasta casserole with just five easy ingredients, plus a little salt and pepper. It's ready for the oven in no time and you can personalize it with whatever you have on hand. The variations are endless.

A few suggestions: use a homemade marinara sauce and fresh basil, try a blend of mozzarella and Parmesan, add breadcrumbs, or, for a moister baked pasta, add in one well-beaten egg. Mix in a package of mixed frozen veggies to make it more nutritious. Enjoy—it's foolproof!
