Ingredients

  • 2 tbsp olive oil
  • 2 large sweet onions, chopped
  • 1 tbsp granulated sugar
  • 1 tsp dried thyme leaves
  • 3/4 tsp salt
  • 1/2 cup whole milk (for pre-dough)
  • 3 tbsp flour (for pre-dough)
  • 2/3 cup whole milk, cold
  • 2 1/2 cups flour
  • 5 tbsp butter, melted
  • 2 tbsp granulated sugar
  • 2 tsp instant yeast
  • 1 tsp dried thyme
  • 1 tsp salt
  • 1/2 tsp garlic powder
  • 1 egg, whisked with 1 tbsp milk (for egg wash)
  • 1 tsp flake sea salt, for sprinkling

Instructions

  1. Heat olive oil in a skillet, then add onions, sugar, thyme, and salt. Cook over low heat, stirring occasionally, until golden and caramelized (35–40 minutes). Let cool.
  2. For the pre-dough, whisk 1/2 cup milk and 3 tbsp flour in a saucepan over medium-low heat until thickened. Transfer to stand mixer bowl.
  3. Add remaining dough ingredients to the pre-dough. Mix until smooth and elastic (10 minutes in mixer or 16–20 minutes by hand). Place in greased bowl, cover, and let rise 1 hour.
  4. Punch down dough and roll into a 14×17-inch rectangle. Spread caramelized onions evenly over dough.
  5. Roll into a 14-inch log, slice into 12 rolls, and place in a parchment-lined casserole dish. Cover and let rise 1 hour.
  6. Preheat oven to 375°F during last 20 minutes of rising. Brush rolls with egg wash, sprinkle with flake salt, and bake 35–40 minutes until golden.
  7. Cool slightly before serving warm.

Notes

  • Add sautéed mushrooms to the filling for extra depth.
  • Sprinkle gruyere or cheddar over the onions before rolling for indulgent flavor.
  • A drizzle of balsamic glaze enhances sweetness in the onions.
  • Fresh thyme may be used—double the amount since it’s milder than dried.
  • Sweet onions caramelize best, but yellow onions work too.
