Spaghetti with tomato sauce is an easy-to-make meal that pleases almost everyone. But you might not want to eat over and over again if you have leftovers. If you don’t feel like repeating the same dinner from the night before, you can re-invent the noodles by combining them with unusual ingredients, or by cooking them in a different style to create a whole new dish.

Baked Spaghetti

Turn leftover spaghetti into casserole the next day. Simply place the spaghetti in a greased baking dish, and cover with spaghetti sauce and sprinkle with cheddar cheese. Bake in the oven at 350 degrees F until the cheese is bubbly and golden brown. You can substitute traditional tomato-based spaghetti sauce with a cream sauce, and add a variety of different cheeses such as Parmesan and mozzarella to create an extra cheesy version. Add other items such as mushrooms, and fresh herbs if you like.

Pan-Fried Spaghetti

Use day old spaghetti to make a stir-fry. Saute frozen vegetables such as peas, carrots, and broccoli in a wok or large skillet with olive oil, then add the spaghetti and soy or teriyaki sauce. Another idea is to saute the leftover pasta in oil, and add any leftover spaghetti sauce you may have. Let the bottom layer of spaghetti and sauce get stuck to the bottom of the pan briefly so it will caramelize and add more flavor. Scrape the pan to distribute the bottom pieces throughout the rest of the spaghetti. The spaghetti should be slightly crispy when it is ready.

Breakfast Spaghetti

Serve leftover spaghetti for breakfast by mixing it in with eggs. To make a spaghetti and egg frittata, scramble eggs, then add the spaghetti and mix until they are well-coated with yolk. Pour the mixture into a well-greased frying pan and let the egg set on the bottom. Check with a spatula to make sure the mixture is slightly browned on the bottom, then flip over and brown the other side before serving. You can also add extra ingredients just as you would with a regular omelet, such as pieces of bacon, diced ham, onions, and vegetables such as spinach or broccoli.

Spaghetti Salad

Although tube and spiral type noodles are more commonly used for pasta salad, there’s no reason why you can’t use spaghetti noodles. Simply chop up the noodles and toss them in a bowl with your favorite pasta salad ingredients, such as Italian dressing, olives, onions, peppers, and grated cheese. You can also add add chopped cold spaghetti on top of a salad made of greens to make it more hearty.
