Leek Bread Pudding (Print Version)

# Ingredients:

01 - 12 cups bread cubes (from 1 large French bread loaf), toasted.
02 - 2 cups Gruyere cheese, shredded (or Comté or Emmental).
03 - 3 cups leeks (about 3-4 leeks, white & light green parts).
04 - ½ tsp kosher salt.
05 - 2 tbsp butter.
06 - 2 tbsp olive oil.
07 - 4 large eggs.
08 - 4 cups milk.
09 - 2 cups half and half.
10 - 1 tsp Dijon mustard.
11 - ½ tsp salt.
12 - ½ tsp white pepper (or black pepper).
13 - 1 tbsp chives (or scallions).
14 - 1 tbsp fresh thyme.
15 - ½ tsp freshly grated nutmeg.

# Instructions:

01 - Preheat oven to 350°F (175°C).
02 - Slice leeks into ½-inch rounds. Soak them in lukewarm water to remove dirt, then strain and pat dry.
03 - Heat a skillet on medium-high. Add leeks and salt, cook for 5 minutes. Lower heat, stir in butter and olive oil, cover, and cook for 20-30 minutes, stirring occasionally until soft and caramelized.
04 - Cut bread into 1-inch cubes. Spread on a sheet pan and toast for 20 minutes until golden and dry. Transfer to a large mixing bowl.
05 - In a separate bowl, whisk together eggs, milk, half and half, Dijon mustard, salt, pepper, chives, thyme, and nutmeg.
06 - Grease a 9x13-inch baking dish. Layer the bottom with ½ cup cheese. Add half of the leek and bread mixture, top with ½ cup cheese. Add the remaining leek mixture and pour in the custard, pressing bread cubes to soak. Let sit for 10 minutes. Top with remaining custard and cheese.
07 - Bake for 1½ hours, until puffed and lightly browned.

# Notes:

01 - Savory Leek Bread Pudding is a hearty, comforting dish with a rich custard base, caramelized leeks, and gooey cheese. It's a perfect choice for a filling side or a main course.
