Zucchini noodles are a healthy, keto-friendly alternative to traditional lasagna noodles. Zucchinis are the perfect shape for making lasagna noodles due to their length and width. In order to get a lasagna-shaped zucchini noodle, you’ll need to use either a sharp knife, a large vegetable peeler, or a mandoline. The noodles should be the same thickness and size so that it cooks evenly (per Parade).
One issue that may arise with vegetable noodles is that they can taste bitter. A simple solution for this is to lay the cut vegetables on a sheet tray and sprinkle them with salt. Let the noodles sit for an hour, then rinse the salt off and dry completely. When it comes to assembling the lasagna, the process is the same as when using noodles. Some recipes, like the one from Healthy Recipes, suggest lightly grilling the zucchini before layering them into a baking dish. The noodles are topped with your sauce of choice, then layer with cheese, and repeat. The whole dish is baked until the cheese is bubbly.
All that’s left to do is dig into a large bowl of guilt-free lasagna.
