Ingredients
Scale
- 6 cups raisin bread (I used 5 cups and 1 of doughnuts), cut into cubes
- 2 cups kale, roughly torn
- 2 onions, roughly chopped and roasted with olive oil and pepper for about 40 minutes at 400 degrees F
- 7 large eggs
- 2 ½ cups milk (I used skim, use what you love)
- ½ teaspoon kosher salt
- 1 teaspoon freshly ground black pepper
- 2 teaspoons ground mustard
- 1 cup grated gruyere cheese
- 1 cup grated cheddar cheese
Instructions
- Preheat oven to 350 degrees F. Place the bread (and potentially doughnuts) on a piece of foil and toast in the oven about 10 minutes to get a little crispy.
- Oil a 9 by 13 inch pan. Once the bread is toasted, place it in an even layer in the pan. Scatter the kale and onions around the bread.
- In a medium bowl, whisk together the eggs, milk, salt, pepper, mustard, and cheeses. Pour over the bread. Press down slightly to make sure the bread is immersed fully in the custard.
- Bake 1 hour to 1hour 15 minutes, until puffed, golden brown, and the custard is fully set. Serve immediately or store in an airtight container in the refrigerator for up to 3 days. Serve cold or reheat in the microwave for about 1 minute.
