Sourdough pretzel bites are the snack you make when the discard jar is full and nobody's in the mood for another loaf: chewy, golden nuggets with a deep pretzel tang, a soft middle, and that unmistakable malty crust from a baking-soda bath. This recipe uses discard for flavor — and the discard actually makes them taste more like real pretzels than a pure-yeast version — plus a little yeast for a same-day rise. They take about 4 hours and come out salty, snackable, and dangerously easy to keep eating.
Why this recipe works
Pretzel character comes from two things: a stiff dough and an alkaline bath. The discard adds acid and a deeper fermented tang, the butter and brown sugar round it out, and the baking-soda soak is what turns an ordinary roll into a pretzel — it raises the surface pH so the crust bakes to that glossy, dark, almost bitter-in-a-good-way shell. Skip the bath and you've made bite-sized dinner rolls; do it right and you get the real thing, baked not fried.
The soda bath
This is the step people skip and then wonder why their pretzels taste like bread. Bring the water to a simmer, kill the heat, and stir the baking soda in slowly — it foams up fast, so don't dump it. Twenty to thirty seconds per bite is enough to set the crust chemistry; longer just makes them more pronounced. Lift them out with a slotted spoon, drain on a towel, and they're ready for egg wash and salt.
Serving and storage
Coarse salt on top is non-negotiable, and a mustard or beer-cheese dip turns these from snack to centerpiece. They're best within a day; freeze the rest for up to 3 months and reheat in the oven, never the microwave, to keep the chew.

Ingredients
Weights in grams are the source of truth; cup measures are approximate.
- 150 g sourdough discard (unfed, straight from the fridge)
- 500 g bread flour (about 4 cups)
- 290 g warm water (about 1 1/4 cups)
- 4 g instant yeast (about 1 1/4 teaspoons)
- 9 g fine salt (about 1 1/2 teaspoons)
- 15 g brown sugar (about 1 tablespoon)
- 30 g soft butter (about 2 tablespoons)
- 1 egg (about 50 g), beaten, for the egg wash
- 40 g baking soda (about 1/4 cup), for the bath
- 20 g coarse pretzel salt or flaky salt, for topping
Method
In a large bowl, whisk the bread flour, brown sugar and salt together.
Warm the water to about 38°C (100°F), stir in the instant yeast, then add the sourdough discard and soft butter and mix until the discard breaks up.
Pour the liquid into the dry ingredients and mix into a firm, only slightly tacky dough.
Knead 8-10 minutes until smooth and elastic — pretzel dough is stiffer than most bread doughs and that's correct.
Cover and let rise 1-1 1/2 hours at room temperature, until doubled.
Divide the dough into 6 pieces, roll each into a rope about 2 cm (3/4 inch) thick, and cut into 2-3 cm (1 inch) bites.
Bring a wide pot of water to a simmer, turn off the heat, and stir in the baking soda carefully — it will foam up, so add it slowly.
Drop the bites in batches into the soda bath for 20-30 seconds each, then lift out with a slotted spoon onto a towel-lined tray to drain.
Arrange the bites on a parchment-lined sheet, brush with egg wash, and sprinkle with coarse salt.
Bake at 200°C (400°F) for 13-15 minutes until deep mahogany brown, rotating the pan halfway, then cool 5 minutes before serving.
Frequently asked questions
Why bake in a baking soda bath instead of just boiling in water?
The alkaline bath is what gives pretzels their signature dark, glossy crust and that distinctive malty, almost soapy pretzel flavor — plain water boiling gives you a dinner roll, not a pretzel. Use food-grade baking soda added to off-the-boil water (it foams), and don't substitute lye unless you know how to handle it safely. Twenty to thirty seconds per bite is enough.
Can I make these with discard only, no commercial yeast?
Yes, with a long cold ferment — shape the bites, retard 8-12 hours in the fridge, then bath and bake. The yeast here is a same-day shortcut; the discard provides the deeper tang that actually makes these taste more pretzel-like than a pure-yeast version. Expect a more sour, chewier bite either way you go.
Why are my pretzel bites pale and tastes like bread?
Two likely causes: the soda bath was too weak or too short, or the oven wasn't hot enough. Use the full 40 g baking soda, give each bite a full 20-30 seconds, and bake hot at 200°C (400°F) until they're a deep brown, not golden. Pale pretzels skipped the alkalinity step in flavor as well as color.
How do I store pretzel bites and reheat them?
They're best the day they're made. Keep uncovered or loosely tented at room temperature for a day, or freeze for up to 3 months. Reheat in a 180°C (350°F) oven for 5-6 minutes to bring back the chew — the microwave makes them tough and rubbery, so skip it.
