You've seen them dozens of times in the grocery produce section - spiralized veggie "noodles". They're made from sweet potatoes, beets, carrots, and the original zucchini zoodle. They look tasty, fun, and healthy....but what do you really do with them?
First, let me tell you what you *don't* do, and that's pretend that they are pasta. They are not pasta. At all. They are vegetables, and therefore contain a large amount of water. This means that your zoodle lasagna will be watery and unpleasant, and your family or dinner guests will have to lie when they compliment you on your cooking. Please don't make your family and friends lie. I'm not a fan of pretending a legit food is something else anyway. Tofu, for example: tofu stands on its own and can be used in many delicious dishes; you set yourself up for failure and disappointment when you try to turn it into chicken or beef.
So let's embrace the veggie "noodle" on its own merits and work with it accordingly.
Because zoodles are a vegetable (not a pasta, now) they are a natural for salads and make a fun, colorful addition. Toss a handful into your regular salad mix or scatter them on top for pretty presentation. Mix and match, because vegetables all love each other and want to be together.
Zoodle beds are another favorite with steaks or other grilled/pan-fried meats. Zoodles are so thin that they don't really need cooking, so all you do is make a zoodle bed on each plate, then top with a portion of the meat. The heat from the meat will wilt the zoodles a bit, but keep them firm. Then if you have a pan sauce, just pour it over the top. Zucchini works, of course, but beets are my bed of choice.
But if you must cook your zoodles:
Roasting zoodles works because it takes some of the moisture out of them. The key is to hit them with high heat for a short amount of time. Turn your oven to 450*, toss your veggie noodles with olive oil, then spread them out in a baking sheet. Roast for about 5 minutes, toss them, and give them another 5 minutes. Adjust time depending on how soft you want your zoodles. Serve as is, or hit them with a dusting of Parmesan cheese. Sweet potatoes in particular work with this method.
Zoodles also stir-fry nicely - vegetables, remember? Heat your pan on medium-high with a little oil - let it get nice and hot - and throw in your zoodles, tossing/stirring constantly for about 3 minutes. Then you can toss them with your favorite sauce/marinade. Make sure you keep it light, though; bottled Caesar dressing is one of my favorites. OR toss the hot zoodles with shredded cheese, which will melt and get comforty, because....cheesy veggies, ya'll.
Zoodles do well with pesto, Asian sauces, and most other light sauces/condiments. If you're going to leave your zoodles raw, toss them with your preferred condiment/sauce and let them marinate for a few minutes. If you're going to cook them, do so in their naked state and add your sauce afterward to reduce the watery. Another tip for keeping the water at bay is don't salt the raw veggies - ever! Salt causes vegetables to release moisture and you'll end up with a soggy blob of mess.
Certainly you can spiralize your own veggies, but let me tell you it is a raving pain in the you-know. Now that so many supermarkets are carrying pre-spiralized veggies, there's no real need to delve into the frustration and mess of doing it yourself. I mean, how much time do you really want to spend preparing vegetables?
