Savory Leek Bread Pudding is a hearty and comforting dish that combines toasted bread cubes, rich Gruyere cheese, and caramelized leeks. The custard is spiced with Dijon mustard, nutmeg, and fresh herbs like thyme and chives, creating a flavorful and filling dish perfect for a fall or winter meal. The layers of bread, cheese, and caramelized leeks bake into a golden, fluffy casserole that's perfect as a main course or a savory side dish.
INGREDIENTS
- Bread cubes: 12 cups, from 1 large French bread loaf, toasted
- Gruyere cheese: 2 cups, shredded (or substitute with Comté or Emmental)
- Leeks: 3 cups, sliced (about 3-4 leeks, white & light green parts)
- Kosher salt: ½ tsp
- Butter: 2 tbsp, for caramelizing the leeks
- Olive oil: 2 tbsp, for caramelizing the leeks
- Large eggs: 4, for the custard base
- Milk: 4 cups
- Half and half: 2 cups
- Dijon mustard: 1 tsp, for a hint of tanginess
- Salt: ½ tsp
- White pepper: ½ tsp (or black pepper, if preferred)
- Chives: 1 tbsp, finely chopped (or scallions)
- Fresh thyme: 1 tbsp, for a fragrant, earthy note
- Freshly grated nutmeg: ½ tsp
INSTRUCTIONS
- Step 1:
- Preheat your oven to 350°F (175°C). Slice the leeks into ½-inch rounds and soak them in lukewarm water to remove any dirt. Strain and pat dry.
- Step 2:
- In a skillet, heat medium-high heat. Add leeks and salt, cooking for 5 minutes. Then lower the heat, stir in butter and olive oil, cover, and cook for another 20-30 minutes, stirring occasionally, until the leeks are soft and caramelized.
- Step 3:
- While the leeks are caramelizing, cut the bread into 1-inch cubes and toast them on a sheet pan in the oven for 20 minutes, until golden and dry. Transfer to a large mixing bowl.
- Step 4:
- In a separate bowl, whisk together eggs, milk, half and half, Dijon mustard, salt, pepper, chives, thyme, and nutmeg to create the custard mixture.
- Step 5:
- Grease a 9x13-inch baking dish. Layer the bottom with ½ cup of shredded cheese. Add half of the leek and bread mixture, topping with ½ cup of cheese. Add the remaining leek mixture and pour the custard over it, pressing the bread cubes gently to soak. Let sit for 10 minutes. Top with remaining custard and cheese.
- Step 6:
- Bake for 1½ hours, until the bread pudding is puffed and lightly browned on top.
Serving and Storage Tips
