Use day-old sourdough bread to make this easy sourdough French toast. The sturdy texture prevents sogginess, resulting in a crispy exterior and a rich, custardy center perfect for weekend brunch.

Ingredients

Scale
  • 6 thick slices day-old sourdough bread
  • 4 large eggs
  • 1 cup half-and-half (or whole milk)
  • 2 tablespoons granulated sugar
  • 1 teaspoon pure vanilla extract
  • 1/2 teaspoon ground cinnamon
  • 1/4 teaspoon ground nutmeg
  • Pinch of salt
  • 2 tablespoons unsalted butter, for cooking
  • Maple syrup and powdered sugar, for serving

Instructions

  1. In a shallow dish, whisk together the eggs, half-and-half, granulated sugar, vanilla extract, cinnamon, nutmeg, and salt until fully combined. This creates your custard base.
  2. Heat a large griddle or non-stick skillet over medium heat. Add half of the butter and let it melt until it sizzles slightly.
  3. Dip one slice of sourdough bread into the egg mixture, allowing it to soak for about 15 to 20 seconds per side. Sourdough is sturdy, but you want it saturated enough for a custardy interior.
  4. Place the soaked slice onto the hot griddle. Repeat with the remaining slices, working in batches to avoid overcrowding the pan.
  5. Cook for 3 to 4 minutes per side, until the French toast is golden brown and has crispy edges. Adjust the heat if the outside browns too quickly before the inside cooks.
  6. Remove the cooked French toast from the skillet and keep warm while you cook the remaining slices, adding more butter to the pan as needed.
  7. Serve immediately topped with maple syrup and a dusting of powdered sugar for a comforting breakfast classic.

Notes

  • Using thick-cut, day-old sourdough bread is key for achieving the best texture—crispy outside and soft inside.
  • For a richer flavor, substitute half-and-half with heavy cream.
  • If you prefer a stronger spice flavor, increase the cinnamon to 3/4 teaspoon.
