Step-by-Step Instructions

1. Caramelize the Onions

  • Heat 2 tablespoons of olive oil in a skillet over medium heat.
  • Add the sliced onions and sprinkle with salt (and sugar, if using).
  • Cook, stirring occasionally, for 20–25 minutes until the onions turn golden brown and caramelized.
  • Remove from heat and let cool.

2. Preheat the Oven

  • Preheat your oven to 350°F (175°C).
  • Grease a 9×5-inch loaf pan with cooking spray or line it with parchment paper.

3. Mix the Dry Ingredients

  • In a large bowl, whisk together the flour, baking powder, baking soda, salt, black pepper, and dried thyme or rosemary (if using).

4. Mix the Wet Ingredients

  • In a separate bowl, whisk the eggs, olive oil, and Greek yogurt (or sour cream) until smooth and well combined.

5. Combine Wet and Dry Ingredients

  • Gradually mix the wet ingredients into the bowl with the dry ingredients. Stir until just combined.
  • Gently fold in the spinach, shredded cheese, and cooled caramelized onions.
  • If the batter is too thick, add milk one tablespoon at a time until the consistency is scoopable.

6. Bake the Bread

  • Pour the batter into the prepared loaf pan, smoothing the top with a spatula.
  • Bake in the preheated oven for 45–50 minutes, or until a toothpick inserted into the center comes out clean.
  • Let the bread cool in the pan for 10 minutes before transferring it to a wire rack to cool completely.

Pro Tips for Success

Caramelize Perfectly

  • Keep the heat on medium-low and stir occasionally. Patience is key for rich, sweet caramelized onions.

Don’t Overmix

  • Overmixing can result in dense bread. Stir just until the ingredients are combined.

Choose Your Cheese

  • Gruyere adds nuttiness, Parmesan provides saltiness, and cheddar melts beautifully for a gooey texture.

Customizations for Your Bread

  • Add Protein: Toss in crumbled cooked bacon or sausage for extra heartiness.
  • Switch the Greens: Substitute spinach with kale, arugula, or Swiss chard.
  • Herbal Notes: Use fresh herbs like parsley, dill, or basil instead of dried.
  • Spice It Up: Add a pinch of red pepper flakes for a spicy kick.

Serving Suggestions

  • Breakfast: Pair with scrambled eggs or avocado slices for a balanced start to your day.
  • Lunch: Serve alongside tomato soup, chicken noodle soup, or a fresh green salad.
  • Dinner Side: Complement roasted chicken, grilled salmon, or veggie stir-fry.
  • Snack: Enjoy on its own, warmed with a pat of butter or a drizzle of olive oil.
