Sourdough Discard Pasta: Tender, Tangy, and Delicious

Pasta isn't usually associated with sourdough, but adding discard to pasta dough produces pasta that's slightly more tender, slightly more flavorful, and uses up extra discard at the same time. Here's the technique.

The recipe

For 4 servings of fresh pasta:

• 200g all-purpose flour
• 100g semolina flour (or more all-purpose if no semolina)
• 100g sourdough discard
• 2 large eggs
• 1 tbsp olive oil
• 1 tsp salt

Method

Mix

On a clean counter, mound the flours. Make a well in the center.

Add eggs, discard, oil, and salt to the well.

With a fork, gradually beat the wet ingredients while incorporating flour from the edges of the well.

Knead

Once it forms a rough dough, knead by hand for 8–10 minutes. The dough should be smooth and slightly tacky.

Rest

Wrap in plastic. Rest 30 minutes (or up to 24 hours in the fridge).

Roll

Divide the dough into 4 pieces. Keep covered while working.

Using a pasta roller (or rolling pin), thin each piece progressively. Final thickness depends on the pasta:

• Tagliatelle: setting 6 (medium-thin)
• Pappardelle: setting 5 (slightly thicker)
• Lasagna sheets: setting 7 (thin)
• Ravioli: setting 7 (thin enough to see your hand through)

Cut

Use a knife or pasta cutter to shape:

• Tagliatelle: 1/4-inch wide ribbons
• Pappardelle: 1-inch wide ribbons
• Fettuccine: 1/3-inch wide ribbons
• Lasagna: 4-inch wide sheets
• Ravioli: small squares with filling

Cook

Boil heavily salted water. Fresh pasta cooks fast: 2–3 minutes for thin, 4–5 minutes for thick.

Why discard works

Sourdough discard adds:

• Slight tang
• Tenderness (the acid relaxes gluten)
• Subtle wheat flavor
• Color (slightly more yellow)
• Better hydration management

The pasta is tender, holds sauces well, and has more character than plain egg pasta.

Hydration adjustments

Discard is about 50% water by weight. When adding 100g of discard:

• Reduce flour slightly (the discard adds some flour too)
• Or reduce water in the recipe

For this recipe, the discard replaces a small amount of liquid that you would have added with eggs.

Without semolina

If you don't have semolina flour:

• Use 300g all-purpose flour total
• The pasta will be slightly softer
• Slightly less yellow color
• Still excellent

Semolina adds firmness and a slight golden color. It's traditional but optional.

Variations

Whole wheat sourdough pasta

Replace 100g of all-purpose with whole wheat flour. Slightly heartier, nuttier flavor.

Spinach pasta

Add 100g cooked, finely chopped spinach (squeeze dry first). Reduce eggs to 1.

Beet pasta

Add 100g pureed cooked beet. Striking pink-red color.

Squid ink pasta

Add 1 tbsp squid ink. Black pasta, mild seafood flavor.

Herb pasta

Knead in 2 tbsp finely chopped fresh herbs (parsley, basil, chives).

Common mistakes

Pasta is too tough — over-kneaded, or didn't rest long enough. Rest at least 30 minutes.

Pasta is too soft — not enough flour, or too much liquid. Add more flour while kneading.

Pasta breaks during rolling — too dry. Wrap in damp towel for 5 minutes, retry.

Pasta sticks together when cut — not enough flour during cutting. Toss cut pasta with semolina or flour.

Drying pasta for storage

Fresh pasta lasts 1 day in the fridge before quality drops.

For longer storage:

• Drape over a pasta drying rack or hangers
• Air dry for 24–48 hours until brittle
• Store in jars at room temperature for months

Or freeze:

• Toss with semolina to prevent sticking
• Spread on a sheet pan, freeze
• Transfer to bag when frozen
• Cook from frozen (1 minute longer)

A weekly pasta routine

If you make pasta weekly:

• Make 2x recipe (8 servings)
• Cook 4 servings fresh tonight
• Refrigerate 4 servings for tomorrow
• Or freeze 4 for next week

Pasta becomes a regular weeknight option without special preparation.

Sauces that pair

Sourdough discard pasta loves:

• Brown butter and sage
• Lemon and parmesan
• Carbonara (the egg-pasta combination is luxurious)
• Tomato and basil
• Pesto
• Mushroom and cream
• Bolognese

Don't overload the sauce — fresh pasta deserves to be tasted.

Equipment needed

A pasta roller makes life easier but isn't required:

• KitchenAid pasta attachment — $150, attaches to your stand mixer
• Manual pasta roller (Marcato Atlas) — $80, hand-cranked
• Rolling pin — free, harder work but works

A pasta cutter wheel ($5–10) is much faster than a knife but a knife works.

Cost comparison

Store-bought fresh pasta: $5–8 for 1 lb (4 servings).

Homemade sourdough discard pasta: $1.50 for 4 servings (eggs, flour, discard).

You save $3–6 per meal. Plus the discard would otherwise go to waste.

A perfect Sunday

A pasta-making afternoon:

• Build levain (for tomorrow's bread)
• Make pasta dough (15 minutes)
• Roll out and cut (30 minutes)
• Make sauce while pasta dries (30 minutes)
• Cook and serve (5 minutes)

Fresh pasta dinner with tomorrow's bread already in motion.

A note on the egg

Eggs in pasta:

• Add richness and color
• Help bind the dough
• Affect final texture

For eggless pasta, replace eggs with:

• 100g water + 30g additional discard
• The pasta will be slightly less rich but still good

Why this is worth doing

Beyond the cost savings and using up discard, homemade pasta is:

• Better than 95% of store-bought pasta
• A connection to a tradition older than recorded recipes
• Surprisingly easy after a few attempts
• Impressive to serve guests

The first time you serve homemade ravioli at a dinner party, your guests will think you've trained at a culinary school.

A skill that compounds

Once you can make pasta, the variations multiply: stuffed pastas, shaped pastas, regional variations. Italian cuisine opens up.

Sourdough discard pasta is the perfect entry point — the discard adds character, the dough is forgiving, and the result rewards practice.

This isn't a side use of discard. It's a major use, worth keeping in regular rotation.
