Ingredients
  

  • 3 cups All-purpose flour
  • 2 medium Yellow onions
  • cup Castelvetrano Olives or your favorite green olives, pitted, roughly chopped
  • 2 cups Gruyere Cheese shreaded, divided
  • 2 teaspoon Kosher Salt
  • 1 teaspoon Active Dry Yeast
  • 1 tbsp Olive Oil for brushing the cast iron skillet
  • 1 ½ cups warm water plus more as needed (see notes)

For serving:

  • Butter, Sea Salt, Fresh Thyme, Olive Oil

Instructions
 

  • In a heavy-bottomed skillet over medium heat, add sliced onions and cook, stirring every few minutes until golden and caramelized but not mushy (15-20 mins). See more tips for caramelizing onions. Set aside and cool. Makes about 1 cup of caramelized onions depending on the onion's size.
  • In a medium mixing bowl combine the flour and salt and gently mix. (See note 1 below.) Add ¾ cup of the cooled onions, chopped olives, half of the gruyere cheese, and yeast. Gently mix until well combined. Slowly stir in the water a little at a time until a firm, but sticky dough forms. (See note 2 below, and the photos in the step-by-step above for reference.) Cover the dough with plastic wrap and a paper towel and set in a warm place for 4 hours or until doubled in size. (See notes 3 and 4.)
  • Preheat your oven to 425℉ and position a rack in the center
  • Using a pastry brush, brush the inside of the cast iron skillet with a thin coat of olive oil. Using a rubber spatula, gently transfer the dough to the cast iron skillet (see note 5).
  • Bake for 15 minutes. Remove from the oven and top with the remaining gruyere cheese. Bake another 15-20 minutes or until golden brown and cooked through.
  • Remove from the oven and let the bread sit in the cast iron skillet for 5 minutes, then remove from the skillet, transfer to a wire rack, and cool for another 25-30 minutes (note 6).
  • Slice and serve with butter topped with fresh thyme, flaky seas salt and a drizzle of olive oil.

Tips + Tricks

    1. Measure accurately: For consistent results, spoon the flour into the measuring cup and level with a knife.
    2. Adjust hydration: No-knead bread recipes typically have a high hydration level, but you may need to adjust it slightly  (I recommend adding 1 tablespoon at a time) depending on factors like humidity and the type of flour you're using. The dough should be sticky but still manageable.
    3. Be patient with rise/fermentation: The key to developing flavor in no-knead bread is allowing the dough to ferment slowly over a long period. Four hours is the shortest amount of time needed for this dough to rise, however, the fermentation period can range from 4 to 24 hours or even longer.
    4. Experiment with rising/fermentation time and temperature: You can adjust the fermentation time and temperature to suit your schedule and preferences. A longer fermentation at cooler temperatures (such as in the refrigerator) develops more complex flavors, while a shorter fermentation at warmer temperatures speeds up the process.
    5. Handle the dough gently: Since you're not kneading the dough, it's important to handle it gently to avoid deflating it too much. Use a light touch when transferring it to the cast iron skillet.
    6. Let it cool: Allow the bread to cool in the skillet for a few minutes before transferring it to a wire rack to cool completely. This helps prevent the crust from becoming soggy.
