Most gluten-free pastas shouldn’t be rinsed after boiling, similar to regular wheat pasta. When you rinse pasta, the water flushes away the starches that were released during cooking. These starches are important as they allow pasta sauce to stick properly. However, some varieties are better rinsed, so be sure to check the box for cooking instructions. If you are making hearts of palm pasta, we recommend rinsing and draining these low-carb noodles before cooking with them. This prep step helps the noodles lose some of their hearts of palm flavor and makes them taste and feel more like regular pasta.
