Gruyère & Caramelised Onion Pretzels Recipe
Introduction
These Gruyere & caramelised onion pretzels offer a delicious twist on a classic snack. Soft, chewy pretzels are filled with sweet caramelised onions and topped with nutty, melted Gruyere cheese. Perfect for sharing or enjoying as a savoury treat at any time of day.

Ingredients
- 20g salted butter
- 1 onion, finely diced
- 500g strong white bread flour, plus extra for dusting
- 7g instant yeast
- 1 tbsp light brown soft sugar
- Flavourless oil, for proving
- 5 tbsp bicarbonate of soda
- 1 egg, beaten
- 100g Gruyère, coarsely grated
Instructions
- Step 1: Melt the butter in a small saucepan over medium heat. Once it starts to foam, add the diced onion and a pinch of salt. Cook gently for 15-20 minutes, stirring often, until the onions are golden and caramelised. Spread the onions out on a plate and allow to cool completely.
- Step 2: In the bowl of a stand mixer fitted with a dough hook, combine the flour, yeast, sugar, and 1 teaspoon salt. With the mixer running, gradually pour in 280ml lukewarm water and knead the dough for 5-6 minutes until smooth. Turn the dough onto a lightly floured surface and shape it into a ball. Place it in an oiled bowl, cover, and leave to prove for 1-2 hours until doubled in size.
- Step 3: Tip the dough onto a floured surface and gently knock it back. Roll it out into a flat rectangle, then sprinkle the cooled caramelised onions over the surface. Knead the dough gently to distribute the onions evenly. Divide the dough into 12 equal logs and let them rest for 5-10 minutes.
- Step 4: Using your palms, roll each dough piece into a rope about 35-40cm long. Shape each rope into a pretzel by forming a U-shape with the curve facing you, crossing the ends over twice to create a twist, then folding the ends down to press into the base of the U. Place the pretzels on a baking tray lined with parchment, cover with a clean tea towel, and allow to prove for 20 minutes.
- Step 5: While proving, bring 2.5 litres of water to a boil in a large saucepan. Stir in the bicarbonate of soda until dissolved. Preheat the oven to 200°C (180°C fan)/gas mark 6.
- Step 6: Working in batches, gently lower each pretzel into the boiling water. Boil for 30 seconds on each side, using a slotted spoon or tongs to keep them submerged if needed. Remove with a slotted spoon and place back on the baking tray. Brush each pretzel with beaten egg, then sprinkle with grated Gruyère and a little flaky sea salt.
- Step 7: Bake the pretzels for 20-25 minutes until they turn a deep golden brown and the cheese is melted and bubbling. Allow to cool for 15 minutes before serving.
Tips & Variations
- For a vegetarian version, ensure your yeast and bicarbonate of soda are free from animal products and omit the butter or replace with plant-based alternatives.
- Try adding fresh thyme or rosemary to the caramelised onions for an herbal note.
- Use different cheeses like sharp cheddar or Emmental if Gruyère is unavailable.
- Sprinkle some sesame or poppy seeds on top before baking for extra texture and flavor.
Storage
These pretzels are best enjoyed fresh on the same day. To store, let them cool completely, then wrap tightly and freeze for up to one month. Reheat in a preheated oven at 180°C (160°C fan) for 8-10 minutes until warmed through. Avoid microwaving to maintain their chewy texture.

FAQs
Can I make the dough by hand instead of using a mixer?
Yes, you can knead the dough by hand on a floured surface for about 10 minutes until smooth and elastic. It may take a bit longer but works just as well.
What does boiling the pretzels in bicarbonate of soda do?
Boiling the pretzels in bicarbonate of soda water gives them their characteristic chewy crust and deep golden color by partially cooking the exterior before baking and triggering the Maillard reaction.

Ingredients
Caramelised Onions
- 20g salted butter
- 1 onion, finely diced
- Pinch of salt
Dough
- 500g strong white bread flour, plus extra for dusting
- 7g instant yeast
- 1 tbsp light brown soft sugar
- 1 tsp salt
- 280ml lukewarm water
- Flavourless oil, for proving
Boiling Solution and Topping
- 5 tbsp bicarbonate of soda
- 1 egg, beaten
- 100g Gruyere, coarsely grated
- Flaky sea salt, to sprinkle
Instructions
- Caramelise the Onions: Melt the butter in a small saucepan over medium heat until foaming. Add the finely diced onion and a pinch of salt. Cook on medium-low heat for 15-20 minutes, stirring frequently, until the onions turn golden and caramelised. Spread on a plate and let cool completely.
- Prepare the Dough: In the bowl of a stand mixer fitted with a dough hook, combine the flour, instant yeast, sugar, and 1 tsp salt. With the mixer on, gradually add 280ml lukewarm water and knead the dough for 5-6 minutes until smooth. Turn the dough out onto a lightly floured surface, shape into a ball, then place in an oiled bowl. Cover and allow to prove for 1-2 hours until doubled in size.
- Incorporate the Onions: Turn the risen dough onto a floured surface and knock it back to deflate. Roll it out into a flat rectangle, then evenly scatter the cooled caramelised onions over the surface. Knead gently to distribute the onions throughout the dough. Divide the dough into 12 equal logs and let rest for 5-10 minutes.
- Shape the Pretzels: Roll each piece of dough into a rope about 35-40cm long. Form a U-shape with the rope, cross the ends over twice to create a twist, then fold the ends down pressing them into the curve of the U. Repeat for all pieces and place them on a baking tray lined with parchment paper. Cover with a clean tea towel and let prove for 20 minutes.
- Boil the Pretzels: While pretzels are proving, bring 2.5 liters of water to a boil in a large saucepan. Dissolve 5 tablespoons of bicarbonate of soda in the boiling water. Working in batches, gently lower each pretzel into the soda water. Boil each side for 30 seconds using a slotted spoon or tongs to keep them submerged if needed. Remove and place back on the baking tray.
- Prepare for Baking: Brush each boiled pretzel with beaten egg, then sprinkle with grated Gruyere cheese and some flaky sea salt.
- Bake: Preheat the oven to 200°C (180°C fan)/gas mark 6. Bake the pretzels for 20-25 minutes until they are deep golden brown and the cheese is melted and bubbling.
- Cool and Serve: Remove from the oven and allow the pretzels to cool for 15 minutes. Serve warm. These pretzels are best enjoyed on the day but can be frozen for up to one month.
Notes
- Use strong white bread flour for the best chewy texture in the pretzels.
- Caramelise onions slowly over low heat to bring out their natural sweetness without burning.
- Boiling pretzels in bicarbonate of soda water gives them their characteristic chewy crust and shiny appearance.
- Ensure the water is at a rolling boil before adding the pretzels for best results.
- You can substitute Gruyere with other melting cheeses like Emmental or sharp cheddar if desired.
- For an extra crunchy crust, brush pretzels with egg wash and sprinkle cheese just before baking.
- Store leftover pretzels in an airtight container at room temperature for up to two days or freeze for up to one month.
