- 4 large yellow onions, thinly sliced
- 2 tablespoons olive oil (or butter)
- 1 teaspoon sugar (optional, to enhance caramelization)
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1 teaspoon fresh thyme leaves (or 1/2 teaspoon dried thyme)
- 1/4 cup beef or vegetable broth (to deglaze the pan)
For the Bread:
- 3 1/2 – 4 cups all-purpose flour
- 1 packet (2 1/4 teaspoons) active dry yeast
- 1 teaspoon salt
- 1 tablespoon sugar
- 1 cup warm water (about 110°F/45°C)
- 1/4 cup olive oil (plus extra for greasing)
- 1 cup shredded Gruyère cheese (or substitute Swiss or mozzarella)
- Optional: Fresh parsley or thyme for garnish
Step-by-Step Instructions
1. Caramelize the Onions
- Heat olive oil (or butter) in a skillet over medium heat. Add the sliced onions and cook, stirring occasionally, for 20–30 minutes, or until golden brown and caramelized.
- If the onions start to stick, add a splash of broth to deglaze the pan and scrape up any flavorful bits.
- Stir in the sugar, salt, pepper, and thyme during the last few minutes of cooking. Set aside to cool.
2. Prepare the Dough
- In a large mixing bowl, dissolve the yeast and sugar in warm water. Let it sit for 5–10 minutes until frothy.
- Add 3 1/2 cups of flour, salt, olive oil, and half of the caramelized onions to the yeast mixture. Stir until a shaggy dough forms.
- Gradually add more flour (up to 4 cups total), kneading until the dough is smooth and elastic (about 5–7 minutes). The dough should be slightly tacky but not sticky.
3. First Rise
- Place the dough in a lightly oiled bowl, turning it to coat. Cover with a towel and let it rise in a warm place for 1 hour, or until doubled in size.
4. Shape the Loaf
- Punch down the dough and transfer it to a floured surface. Flatten it into a rectangle, leaving a border around the edges.
- Spread the remaining caramelized onions evenly over the dough and sprinkle with shredded Gruyère cheese.
- Roll the dough tightly into a log, tucking the ends underneath. Transfer it to a greased loaf pan.
5. Second Rise
- Cover the loaf pan with a towel and let the dough rise again for 30–45 minutes, or until it puffs above the rim of the pan.
6. Bake
- Preheat your oven to 375°F (190°C).
- Bake the loaf for 30–35 minutes, or until golden brown and the internal temperature reaches 190°F (88°C).
- Optional: Brush the top with melted butter and sprinkle with fresh herbs for added flavor and presentation.
7. Cool and Serve
- Let the loaf cool in the pan for 10 minutes, then transfer it to a wire rack to cool completely (or slice and serve warm).
- Slice and enjoy with butter, soups, or as a base for gourmet sandwiches.
Tips for Success
- Use Low Heat for Caramelizing: Cook the onions slowly to develop their natural sweetness without burning.
- Don’t Skip the Cheese: Gruyère adds a nutty, melty element that complements the onions beautifully.
- Experiment with Herbs: Try rosemary, sage, or oregano for a different flavor profile.
- Make Ahead: Freeze the baked loaf for up to 3 months. Thaw and reheat in the oven before serving.
