Spinach Dip Hot Bread

Ingredients

  • 6 tablespoons unsalted butter, divided
  • 2 tablespoons all-purpose flour
  • ¾ cup whole milk
  • ¾ cup heavy cream
  • 1 ¼ teaspoons kosher salt, divided
  • ¾ teaspoon ground white pepper, divided
  • 1 ½ cups chopped yellow onion (about 1 medium onion)
  • 10 ounces fresh baby spinach
  • 14 ounces Der Smoked Alpen Cheese, shredded
  • 1 (24-ounce) round sourdough boule
  • 1 tablespoon chopped Calabrian chiles (from a jar)
  • ⅓ cup shredded low-moisture part-skim mozzarella cheese

Instructions

  • Preheat your oven to 450°F. In a small saucepan, melt 2 tablespoons of butter over medium heat. Whisk in the flour until smooth, about 1 minute.
  • Slowly add the milk and cream, whisking constantly to prevent lumps. Bring the mixture to a boil, then reduce heat to low and simmer for 20 minutes, stirring occasionally, until thickened. Stir in ¾ teaspoon salt and ¼ teaspoon white pepper, then remove from heat.
  • Meanwhile, melt the remaining ¼ cup of butter in a large Dutch oven over medium heat. Add the chopped onion and cook, stirring occasionally, until softened, about 6 minutes.
  • Add the spinach and cook, stirring often, until the liquid evaporates and the pot is dry, about 4 minutes.
  • Pour the milk mixture into the Dutch oven with the spinach and onion. Stir well to combine.
  • Mix in the Der Smoked Alpen Cheese and the remaining salt and pepper. Remove from heat.
  • Cut the sourdough boule into 5 slices, each about 1-inch thick. Cut almost all the way through, leaving the bottom crust intact. Slice each piece in half lengthwise, again leaving the bottom crust intact.
  • Arrange the boule on a baking sheet lined with parchment paper or foil. Spoon the spinach-cheese mixture evenly between the bread slices. Top with Calabrian chiles and mozzarella.
  • Bake in the preheated oven until the top is golden brown and the filling is hot and bubbly, 7-10 minutes.
