Overnight Yeast-Raised Belgian Waffles (Brown Butter Method)

A brown-butter, overnight-fermented belgian waffles recipe with whipped egg whites folded in for a shatter-crisp shell and custardy center.

Ingredients

Scale
  • 2 cups whole milk, warmed to 110°F
  • 1 packet (2 1/4 tsp) active dry yeast
  • 1 tbsp granulated sugar
  • 1/2 cup unsalted butter, browned and slightly cooled
  • 2 large eggs, separated
  • 1/2 tsp fine sea salt
  • 2 1/4 cups all-purpose flour
  • 1/2 tsp baking soda
  • 1 tsp vanilla extract
  • pinch of cream of tartar (optional, for whipping whites)
  • neutral oil or melted butter, for greasing the iron

Instructions

  1. Brown the butter in a light-colored saucepan over medium heat, swirling constantly, until it foams, then turns golden with nutty brown flecks and smells toasted, 5-7 minutes. Pour into a bowl to cool slightly.
  2. Warm the milk to about 110°F. Whisk in the yeast and sugar and let stand 5-10 minutes, until foamy on top.
  3. In a large bowl, whisk the flour and salt. Whisk in the yeast-milk mixture, browned butter, egg yolks, and vanilla until you have a smooth, loose batter.
  4. Cover the bowl and refrigerate overnight, 8-12 hours. The batter will rise, bubble, and smell faintly tangy.
  5. The next morning, whisk the baking soda into the cold batter — it will fizz and deflate slightly; that"s expected.
  6. Whip the egg whites (with cream of tartar, if using) to soft peaks. Fold into the batter in two additions, gently, until just combined.
  7. Preheat and lightly grease a Belgian waffle iron. Ladle in batter (start with 3/4 cup and adjust to your iron"s size), close, and cook until deep golden and steam stops escaping, 4-5 minutes.
  8. Serve immediately, or hold waffles on a wire rack in a 200°F oven while you finish the batch — never stack them hot, or they"ll steam and go soft.

Notes

Swap in bread flour for a chewier, more structured interior, or replace 1/2 cup of the all-purpose flour with dark rye for an even nuttier match to the brown butter. Batter keeps in the fridge up to 24 hours if you need to push the timeline. Cooked waffles freeze well in a single layer, then bagged — reheat straight from frozen in a toaster or 375°F oven until crisp, never in the microwave, which turns them soft.
