Step-by-Step Cooking Instructions
The process of making these caramelized onion buns is a rewarding one. It takes a little time, but the results are definitely worth the wait. Follow these steps, and you’ll have freshly baked caramelized onion buns ready to enjoy.
Start by heating a large skillet over medium heat. Add a tablespoon of butter and let it melt. Once the butter is melted, add the sliced onions to the skillet. Stir occasionally to prevent them from burning. As the onions begin to soften, lower the heat to medium-low. Stir them frequently for the next 20-25 minutes, letting them turn golden brown and develop a rich, sweet flavor. Add the brown sugar after about 10 minutes of cooking to help enhance the caramelization process. If you want an added layer of flavor, splash a little balsamic vinegar into the mix. This step gives the onions a deep, savory-sweet profile. Once they are perfectly caramelized, remove them from the heat and set them aside to cool.
In a small bowl, combine the warm water, sugar, and yeast. Stir gently to dissolve the sugar and let the mixture sit for 5-10 minutes until it becomes frothy. This step is crucial as it activates the yeast, ensuring that the dough rises properly.
In a large bowl, combine the all-purpose flour and salt. Create a well in the center, and pour in the activated yeast mixture, milk, and olive oil. Stir everything together using a spoon until a dough starts to form. Transfer the dough to a floured surface and knead it for about 8-10 minutes until it becomes smooth and elastic. The dough should feel soft and slightly tacky but not too sticky. If it’s too sticky, sprinkle in a bit more flour. If it’s too dry, add a little more water.
Once the dough is kneaded, place it in a lightly oiled bowl, turning it around so the dough is coated with oil on all sides. Cover the bowl with a clean kitchen towel and let the dough rise for about 1 hour, or until it doubles in size. The dough needs warmth to rise properly, so place it in a warm, draft-free spot.
After the dough has risen, punch it down gently to release any air bubbles. Divide the dough into 10 to 12 equal portions. Roll each portion into a ball and then flatten it slightly to form a bun shape. Place the shaped dough balls on a baking sheet lined with parchment paper. Leave some space between each one to allow them to expand as they rise.
Cover the shaped buns with a kitchen towel and let them rise for another 30 minutes. During this second rise, the buns will puff up and become light and airy.
Preheat your oven to 375°F (190°C). While the buns are rising, beat the egg in a small bowl. Once the buns have finished rising, brush the egg wash over the top of each bun to give them a golden, shiny finish when baked. Bake the buns in the preheated oven for 18-22 minutes or until they are golden brown on top and sound hollow when tapped on the bottom. Allow the buns to cool slightly before slicing.
After the buns have cooled for a few minutes, slice them open and fill them with the caramelized onions. You can add extra ingredients like cheese, meats, or herbs if you like. Serve immediately, or store in an airtight container for later.
Tips for Customizing the Recipe

While this recipe is delicious as-is, there are plenty of ways you can make it your own. Here are a few ideas to personalize your caramelized onion buns:
Rosemary or thyme work wonderfully with caramelized onions, adding a fragrant, earthy flavor to the buns.
If you’re a cheese lover, add a slice of cheese (such as cheddar or gouda) inside the buns along with the caramelized onions. The melted cheese creates a decadent, savory treat.
For a spicy twist, add a pinch of chili flakes or some finely chopped jalapeños to the caramelized onions.
Swap out the butter and milk for plant-based alternatives like almond milk or vegan butter to make this recipe vegan-friendly.
