Creamy, spiraled sweet potato noodles are so good, you won’t even notice that they're vegetables. While other vegetable "noodles" can become soggy and don't hold up well to a thick, rich sauce, sweet potato noodles have an excellent texture that allows them to keep their shape. They also lend a subtle sweet flavor to a savory sauce, like this rich, velvety cashew cream sauce. This recipe is topped with crispy bacon, but you can easily omit it to make the dish completely vegetarian.

The creamy sauce and hearty noodles are an excellent base for a variety of mix-ins and toppings. Add more herbs like chopped basil or parsley or change up the vegetables to include sautéed kale. Try adding mushrooms with the onions for even more texture and flavor.

  6. Heat a large, shallow saucepan over medium-high heat. Add the diced bacon and cook, stirring frequently, until the bacon is crisped. Using a slotted spoon, remove the bacon, leaving the drippings behind. Reserve the crisped bacon for serving.

  7. Add the olive oil and onion to the pan. Sprinkle with about half of the salt and pepper, and cook over medium-low heat, stirring occasionally, until softened and slightly caramelized, about 20 minutes.

    Get a jump on dinner by making the noodles ahead of time in bulk. They freeze well and can easily be tossed into a dish, no thawing required.

    If you don't have a tool to spiralize the potatoes, many supermarkets carry spiralized vegetables, including sweet potatoes, in the produce section.
