In the world of sourdough baking, there’s a magical ingredient that often gets overlooked: the discard. Yes, that’s right—the portion of sourdough starter that many bakers toss aside during feedings. But what if I told you that this humble discard could be transformed into something truly extraordinary? Say hello to sourdough starter discard pasta—the ultimate marriage of sustainability and deliciousness. On this page, we’ll explore the art of turning sourdough discard into mouthwatering pasta and share some delectable recipe ideas to get you started!

The Beauty of Sourdough Starter Discard:
Before we delve into the pasta-making process, let’s take a moment to appreciate the beauty of sourdough starter discard. While its name may suggest otherwise, discard is far from worthless. It’s packed with flavor and potential, just waiting to be unleashed in the kitchen. By repurposing discard into pasta, we not only reduce food waste but also infuse our dishes with a subtle tang that adds depth and character.

The Sourdough Pasta Making Process:
Turning sourdough starter discard into pasta is surprisingly simple. All you need is flour, eggs, salt, and, of course, your discard. Start by combining the discard with flour and eggs to create a dough, then knead until smooth and elastic. Let the dough rest to allow the gluten to develop, then roll it out and shape it into your desired pasta style—whether it’s spaghetti, fettuccine, or something more adventurous like farfalle or fusilli.

Recipes Ideas for your Sourdough Discard Pasta:
- Sourdough Discard Linguine with Garlic and Olive Oil: Cook freshly made linguine until al dente, then toss it with a generous amount of sautéed garlic, good-quality olive oil, red pepper flakes, and a sprinkle of Parmesan cheese. The tangy undertones of the sourdough discard add a delightful twist to this classic dish.
- Sourdough Discard Ravioli with Ricotta and Spinach: Fill homemade ravioli with a creamy mixture of ricotta cheese, wilted spinach, lemon zest, and a touch of nutmeg. Serve with a light tomato sauce or a drizzle of sage-infused brown butter for a comforting meal that’s sure to impress.
- Sourdough Discard Pappardelle with Wild Mushroom Ragù: Cook wide ribbons of pappardelle until tender, then top them with a hearty ragù made from a medley of wild mushrooms, onions, garlic, and herbs.

kcalIngredients
150 grams Sourdough Starter Discard
250 grams All Purpose Flour
2 Large Eggs
Pinch of Kosher Salt
Instructions
- Add all ingredients to bowl of a stand mixer. Mix on low/medium speed with the paddle attachment until a dough starts to form.
- Switch your paddle attachment out for the dough hook and let the dough hook knead the dough on a low speed for 5 minutes, or until the dough is soft and elastic.
- Form into a ball and cover with a damp cloth or wrap in plastic. I use the air-tight lid to my glass mixing bowl. Allow to rest at room temperature for 30 minutes.
- Divide dough into four equal pieces. Work with one at a time and keep the others covered.
- Roll out the dough into using a pasta machine and cut with a cutter or shape by hand. You can also form into walnut size balls and pass through an extruder.
- Bring a large pot of heavily salted water to a boil. Add the pasta to the boiling water and let boil until cooked through, 2-3 minutes.
- Use a spider strainer and add directly into your sauce. You can also drain in a colander if your sauce isn’t ready.
Notes
- Depending on where you live, the time of year, and the weather, your dough may turn out more or less dry. If your dough is crumby, add water, a teaspoon at a time until it becomes smooth. If your dough is sticky, add more flour.
- Sourdough Pasta is very delicate, so be sure to use it with a shape that doesn’t require it to be rolled out too thin. I have found that it tears a bit more readily that traditional egg dough pasta.
