Easy Sourdough Discard Soft Pretzels

I've made these sourdough pretzels probably forty times at this point, and I still get a little excited every time they come out of the oven. They've got that deep golden crust, the chewy bite, the flaky salt on top — and unlike a lot of homemade pretzel recipes I've tried, they actually stay soft the next day.

Here's the thing you need to know up front: this is an active starter recipe, not a discard recipe. You need a bubbly, recently fed starter — discard will make them dense and sad. If you have a jar of discard you're trying to use up, I'd send you to my 25 sourdough discard recipes instead. Come back when your starter is fed and active.

For everyone else — let's make pretzels.

Quick Answer: What Makes These Work

• Active sourdough starter (not discard) for lift, flavor, and that subtle tang
• Soft, slightly tacky dough — if it's stiff, your pretzels will be dense
• The baking soda bath — non-negotiable, this is what makes a pretzel taste like a pretzel
• Butter brush right out of the oven — locks in that soft, glossy bakery finish
• Total time: about 3.5 hours, mostly hands-off (or overnight in the fridge for deeper flavor)

Makes 8 large pretzels, perfect for game day, a snack board, or feeding a kitchen full of hungry kids.

Why You'll Love These

• Soft and pillowy inside with a real chewy crust
• Naturally fermented flavor from active starter — better than store-bought, not even close
• Flexible timing — same-day if you're motivated, overnight if you're not
• Beginner-friendly — if you can roll a rope of dough, you can shape a pretzel
• Reheats beautifully — soft pretzels at noon the next day, no problem

Ingredients (And Why They Matter)

I'm not going to lecture you about flour science, but a few of these matter more than you'd think.

Active sourdough starter. Bubbly, recently fed, doubled-since-last-feeding active. This isn't where you use up old discard — you need the lift. If your starter is sluggish, give it a feed and try again in a few hours.

Whole milk. Makes the dough soft and rich. Warm it gently — hot milk will kill your starter's momentum.

Brown sugar. Just enough to balance the salt and help with browning. Honey works too if that's what you have.

Unsalted butter, melted. Adds flavor and tenderness. Let it cool a little before mixing in.

Bread flour (or all-purpose). Bread flour gives you a slightly chewier bite, but AP works just fine. Start with 2½ cups and add more only if you need it.

Fine sea salt. Distributes evenly through the dough. Don't skip it — pretzels without salt in the dough taste flat.

The Baking Soda Bath

This is the step people want to skip, and the step you absolutely should not skip.

The quick boil in baking soda water is what gives pretzels that deep mahogany crust, chewy texture, and that real pretzel flavor. Without it, you basically have dinner rolls shaped like pretzels. They're fine. They're not pretzels.

Twenty to thirty seconds in the bath, flip once, and you're done. That's it. That's the whole secret.

If you're new to baking with starter and want to keep yours ready to go for recipes like this, my guide on how to store sourdough discard (fridge vs freezer) covers the basics of keeping your starter healthy and on standby.

Instructions

How to Make Sourdough Pretzels

1. Make the Dough

In a stand mixer (or a big bowl with a wooden spoon), combine:

• 1 cup active sourdough starter
• 1 cup warm whole milk
• 2 tablespoons brown sugar
• 4 tablespoons melted, slightly cooled butter

Stir until well mixed.

Add:

• 2½ cups bread flour (start here, you can add more)
• 1½ teaspoons fine sea salt

Mix until a soft dough comes together. If it feels sticky, add flour one tablespoon at a time until it's tacky but not gluing itself to your hands. Knead 5–7 minutes until smooth and elastic.

The dough should feel pillowy, almost like a baby's cheek. Stiff dough = stiff pretzels. Trust me on this one.

2. Bulk Ferment

Cover the bowl and let the dough rise until it's about 50% bigger — not doubled.

You have two timing options:

• Same day: 3–4 hours at room temperature
• Overnight: 8–12 hours in the fridge (better flavor, more sourdough tang)

I do same-day when I'm feeding a Saturday afternoon football crowd and overnight when I want to feel like a real bakery person on Sunday morning.

3. Shape

Turn the dough out onto a lightly floured counter. Divide into 8 equal pieces (eyeball it or use a scale — I usually eyeball it).

Roll each piece into a 20–22 inch rope. If the dough fights you, let it rest 5 minutes and try again. Shape into classic pretzels or just twist them — twists are easier and taste exactly the same.

Place on parchment-lined baking sheets.

4. Rest

Let the shaped pretzels rest 20–30 minutes, loosely covered. They'll puff slightly. This rest matters — it gives you better oven spring and a softer interior.

5. Baking Soda Bath

Preheat your oven to 425°F (220°C).

In a wide pot, bring to a gentle boil:

• 8 cups water
• ½ cup baking soda

Carefully lower each pretzel in for 20–30 seconds, flipping once. Lift out with a slotted spatula and return to the baking sheet.

6. Egg Wash and Bake

Whisk together:

• 1 egg yolk
• 1 tablespoon milk

Brush generously over each pretzel. Sprinkle with flaky salt (pretzel salt if you have it, kosher salt if you don't).

Bake 12–15 minutes, until deep golden brown. Not pale. Not light caramel. Deep. Brown.

7. The Butter Brush (Don't Skip This Either)

The minute they come out of the oven, brush them generously with melted butter. Let them cool 5 minutes before you tear into one.

This is the difference between a good pretzel and a "where did you buy these?" pretzel. It's 30 seconds of work and it changes everything.

Variations

Once you've made the base recipe, the variations are where it gets fun:

• Cinnamon sugar pretzels — skip the salt, brush with melted butter after baking, then toss in cinnamon sugar. My boys vote for these every time.
• Cheese pretzels — sprinkle shredded sharp cheddar or parmesan on top before baking
• Everything pretzels — swap the flaky salt for everything bagel seasoning
• Pretzel bites — cut the ropes into 1-inch pieces before boiling, bake about 8–10 minutes

Serving Suggestions

These pretzels are great solo, but they really shine with something to dip:

• Honey mustard
• Garlic butter
• Cream cheese spreads

If you're putting these on a party spread, my appetizer portions per person guide will tell you exactly how many you need to make. And if pretzels are going on a bigger snack board, the how to build a charcuterie board guide walks through what to pair them with.

Storage and Reheating

Soft pretzels are best fresh out of the oven (obviously), but they hold up better than you'd think.

Room temperature (2 days max). Airtight container or zip-top bag, tightly sealed. They'll soften but stay good.

Reheat for fresh texture. 300°F oven for 5–7 minutes, or microwave 15–20 seconds. The oven is better. The microwave is faster. Pick your battle.

Skip the fridge. It dries them out fast. Counter or freezer, nothing in between.

Freezer (2 months). Cool completely, then freeze in a zip-top bag. To reheat, bake straight from frozen at 325°F for 8–10 minutes. Brush with a little butter after for extra softness.

Pro tip: If you know you're storing them, hold off on the salt until after reheating. Salt pulls out moisture and makes them soggy.

FAQs

Can I use sourdough discard? No — or rather, you can, but they'll be dense and disappointing. This recipe needs an active, bubbly starter for the lift. If you've got discard to use, my 25 sourdough discard recipes has better options.

Do I have to do the overnight rest? Nope. Same-day works beautifully. The overnight just gives you deeper flavor and a little more tang.

Why are my pretzels pale? Two likely culprits: the baking soda bath wasn't long enough, or they didn't bake long enough. Don't be afraid to leave them in another minute or two. "Deep golden brown" is darker than you think.

Can I make these dairy-free? Yes — swap in plant milk and dairy-free butter. They won't be quite as rich but they'll still be great.

Can I double the recipe? Yes, and you should if you're feeding a crowd. The dough handles doubling well. Just give yourself a second baking sheet.

Final Thoughts

These sourdough pretzels are one of those recipes that look impressive but are actually pretty forgiving once you've made them once. Soft inside, chewy crust, deeply golden, that classic pretzel flavor you can't fake. They're worth making for a Saturday afternoon, game day, or just because you have active starter and an hour.

If you're on a sourdough kick, a few more from the kitchen:

• Old Fashioned Sourdough Cinnamon Rolls — soft, gooey, perfect for slow mornings
• Soft & Fluffy Sourdough Cinnamon Roll Focaccia — the one that always gets asked about
• Double Chocolate Sourdough Pancakes — quick, indulgent, uses active starter
