Leftover Remix: Spaghetti and Marinara Sauce

People won’t even realize these are leftovers!

You know those times when you make a dinner that you’re totally happy with and excited to eat, but then you look at your leftovers the next day and feel uninspired and definitely not super excited to eat them? We hate wasting food, but trying to liven up (sometimes) boring leftovers is a task that even we fail at sometimes. Which is why we tasked ourselves with coming up with a way to make even the most basic of leftovers super enjoyable and delicious…in this case, no one will even recognize the meal we’ve put together out of last night’s leftovers.

So what’s the meal we’re transforming, you’re wondering? It’s classic spaghetti marinara and, we don’t mean to brag, but what we’ve turned it into is seriously impressive. We intentionally kept the two main ingredients (spaghetti and marinara sauce) separate when we were packing them up after dinner, that way we’d have more flexibility with what we could turn them into…which ended up being a replacement for garlic bread, i.e. a cheesy spaghetti loaf, and a hearty veggie minestrone. Using the noodles as bread and the red sauce as the base of our minestrone, these base ingredients get completely repurposed and turned into something brand new (and delicious).

If you read “spaghetti loaf” and thought what in heaven’s name is that, you’re not alone. It sounds pretty outlandish, but stick with us for a minute; this is a dense loaf (it is packed with noodles, after all) that’s stuffed with cheese and an herbed-egg mixture that binds everything together. It bakes in the oven, then is able to be sliced and served as you would any type of bread of loaf…albeit slightly denser, which we’re not mad about. And the spaghetti loaf isn’t the only thing we love about these repurposed leftovers – the soup is great too!

We’re not quite sure why it hadn’t occurred to us sooner, but using tomato sauce as a base for a soup is genius! If you’ve got a half-used jar in the fridge, use it in this recipe. It adds all the tomato you need, plus, it’s already seasoned, so you don’t need to empty out your spice rack. You end up with a veggie-packed, flavorful, healthy soup that’s good anytime of the week. Dip a big ol’ spaghetti loaf slice in your soup and you’re good to go!
