Let’s bring this recipe to life in your kitchen:

1. Preheat your oven to 375°F (190°C). Line a baking sheet with parchment paper for easy cleanup.
2. Using a sharp bread knife, carefully cut the sourdough loaf into a grid pattern. Make sure not to slice all the way through, leaving the base of the loaf intact.
3. In a medium bowl, combine the mozzarella, Parmesan, and chopped spinach. Mix until evenly distributed.
4. In a small saucepan, melt the butter over medium heat. Add the minced garlic, olive oil, oregano, and red pepper flakes. Stir until fragrant, about 2 minutes.
5. Place the loaf on the prepared baking sheet. Gently pry apart the bread sections and evenly distribute the spinach and cheese mixture within the cuts.
6. Brush the top of the bread with the butter and garlic mixture, ensuring every nook and cranny is coated.
7. Season with salt and pepper to taste. If you’re anything like my abuela, a little extra sprinkle of love never hurts!
8. Cover the loaf with aluminum foil and bake for 15 minutes. Remove the foil and bake for an additional 10 minutes, or until the cheese is bubbly and golden brown.
9. Allow the bread to cool for a few minutes before serving. Enjoy the delightful aroma that fills your home!
