Sourdough Onion Pretzel Bites

There is something deeply satisfying about pulling a tray of golden pretzel bites from the oven—the kind that fill your kitchen with the warm, yeasty aroma of freshly baked bread mingled with the sweet perfume of caramelized onions. These Sourdough Onion Pretzel Bites are exactly that kind of recipe: humble in ingredients, rewarding in process, and irresistible at the table. Made with a lively sourdough starter and studded with slow-cooked caramelized onions, each bite carries a depth of flavor that sets it apart from any store-bought snack. Whether you are hosting a gathering or simply treating yourself on a quiet afternoon, these little bites have a way of disappearing fast.

Pin it

The secret to these pretzel bites lies in two unhurried steps: the long caramelization of the onions and the two-hour rise of the sourdough dough. Neither can be rushed, but both reward your patience generously. The baking soda bath is what gives each bite its characteristic chewy crust and deep mahogany color—a classic technique borrowed from traditional German pretzel-making and carried joyfully into the American snack repertoire. Once you have made these, it is very hard to go back to anything else.

Ingredients

• Dough
• 1 cup (240 g) active sourdough starter (100% hydration)
• 2 ½ cups (320 g) bread flour
• ⅔ cup (160 ml) warm water
• 2 tbsp unsalted butter, melted
• 1 tbsp granulated sugar
• 1 tsp fine sea salt
• Onion Mixture
• 1 medium yellow onion, finely diced
• 1 tbsp olive oil
• ½ tsp salt
• Baking Soda Bath
• 6 cups (1.4 L) water
• ¼ cup (60 g) baking soda
• Topping
• 1 egg, beaten (for egg wash)
• Flaky sea salt, for sprinkling
• Optional: minced chives or dried onion flakes

Instructions

Step 1 – Caramelize the onions

In a skillet over medium heat, add olive oil. Add diced onion and ½ tsp salt. Cook, stirring occasionally, until onions are golden and caramelized, about 12–15 minutes. Set aside to cool.

Step 2 – Mix the dough

In a large mixing bowl, combine sourdough starter, bread flour, warm water, melted butter, sugar, and 1 tsp salt. Mix until a shaggy dough forms.

Step 3 – Add onions and knead

Add cooled caramelized onions to the dough. Knead by hand (or with a dough hook) for 7–10 minutes until smooth and elastic.

Step 4 – First rise

Place dough in a lightly greased bowl. Cover and let rise in a warm place for about 2 hours, or until doubled in size.

Step 5 – Preheat oven

Preheat oven to 425°F (220°C). Line two baking sheets with parchment paper.

Step 6 – Shape the bites

Turn dough onto a floured surface. Divide into 4 equal pieces. Roll each piece into a 12-inch (30 cm) rope, then cut each rope into 1-inch (2.5 cm) pieces.

Step 7 – Baking soda bath

Bring 6 cups water to a boil in a large pot. Carefully add baking soda (it will bubble). Working in batches, drop pretzel bites into the boiling water for 30 seconds. Remove with a slotted spoon and arrange on prepared baking sheets.

Step 8 – Egg wash and salt

Brush each bite with beaten egg. Sprinkle with flaky sea salt (and optional toppings).

Step 9 – Bake

Bake for 12–15 minutes, or until deep golden brown.

Step 10 – Serve

Let cool slightly before serving warm.

Zusatztipps für die Zubereitung

Für ein besonders aromatisches Ergebnis empfiehlt es sich, die Zwiebeln wirklich geduldig zu karamellisieren—mindestens 12 bis 15 Minuten bei mittlerer Hitze, bis sie tief golden und weich sind. Wer den Teig noch würziger mag, kann ½ TL Knoblauchpulver direkt in den Teig einarbeiten. Die Natronlösung sollte sprudelnd heiß sein, bevor die Pretzel-Bites hineingegeben werden, damit die typische Kruste entsteht. Ein gutes Pastry-Brush sorgt für einen gleichmäßigen Ei-Anstrich und damit für eine schöne, gleichmäßige Bräunung im Ofen.

Varianten und Anpassungen

Diese Sourdough Onion Pretzel Bites lassen sich auf vielfältige Weise abwandeln. Wer es herzhafter mag, kann getrocknete Zwiebelflocken zusätzlich auf die Bites streuen, bevor sie in den Ofen kommen. Frische Schnittlauch-Streifen als Topping verleihen eine frische, leicht scharfe Note. Das Grundrezept bleibt dabei immer gleich: der Teig aus Sauerteig-Starter, Brotmehl, warmem Wasser, geschmolzener Butter, Zucker und Salz, verfeinert mit den karamellisierten Zwiebeln und gebadet in der Natron-Lösung.

Serviervorschläge

Diese Pretzel Bites schmecken am besten frisch aus dem Ofen, noch leicht warm. Servieren Sie sie mit Senf, einem Käse-Dip oder einem cremigen Zwiebel-Dip—alle drei Varianten passen hervorragend zum herzhaften Sourdough-Aroma. Für ein geselliges Beisammensein können Sie mehrere Dips gleichzeitig anbieten und die Bites in der Mitte des Tisches platzieren, sodass sich jeder nach Belieben bedienen kann. Restliche Bites lassen sich einfrieren und bei 175°C (350°F) in 5–7 Minuten wieder aufwärmen.
