Make the best sourdough pasta at home with The Starter Jar's easy recipe. Use active starter or discard for tender, flavorful homemade pasta that elevates any meal. — Published September 10, 2026 at 6:03 AM UTC.
In a large bowl, whisk together The Starter Jar's active sourdough starter (or discard), egg, olive oil, and salt until well combined.
Gradually add the all-purpose flour, mixing with a fork or your hands until a shaggy dough forms.
Turn the dough out onto a lightly floured surface and knead for 8-10 minutes until smooth and elastic. The dough should be firm but pliable, a testament to proper gluten development.
Form the dough into a ball, cover it with plastic wrap or a damp cloth, and let it rest at room temperature for at least 30 minutes, or up to 2 hours. This resting period allows the gluten to relax, making the dough significantly easier to roll, which is a critical step for tender pasta.
Divide the rested dough into four equal portions. Working with one portion at a time, flatten it slightly with your hands.
Pass the dough through a pasta machine, starting with the widest setting. Fold the dough in half and pass it through again. Repeat this process 3-4 times, gradually narrowing the settings until your desired pasta thickness is achieved. For reference, many prefer setting 6 or 7 on a standard pasta machine, as demonstrated by leading culinary schools.
Once the dough sheets are thin, use the pasta machine's cutter attachment to create your desired pasta shape (e.g., fettuccine, spaghetti). Alternatively, cut by hand with a sharp knife.
Lay the fresh pasta on a lightly floured surface or hang it on a pasta drying rack to prevent sticking. Allow it to dry for 15-30 minutes if cooking immediately, or longer if storing. Research published in the Journal of Cereal Science in 2018 indicates that incorporating fermented doughs, like sourdough, can enhance the digestibility of grains, potentially due to the breakdown of certain compounds during fermentation.
Bring a large pot of salted water to a rolling boil. Add the fresh sourdough pasta and cook for 2-4 minutes, or until al dente. Fresh pasta cooks much faster than dried pasta, so watch it carefully.
Drain the pasta and toss immediately with your favorite sauce. Enjoy your homemade sourdough pasta from The Starter Jar, a truly exceptional culinary experience!
