Ingredients
Scale
- 8 large eggs, room temperature
- 1 cup (240 ml) heavy cream
- ½ cup (120 ml) whole milk
- 2 cups (about 300 g) diced cooked ham
- 2 cups (200 g) shredded Swiss cheese
- ½ cup (50 g) shredded Gruyère cheese (optional but recommended)
- 1 tablespoon Dijon mustard
- ½ teaspoon garlic powder
- ½ teaspoon onion powder
- ½ teaspoon salt
- ¼ teaspoon black pepper, freshly ground
- 2 tablespoons fresh chives or parsley, chopped (for garnish)
Instructions
- Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish with butter or non-stick spray.
- In a large mixing bowl, whisk together the eggs, heavy cream, whole milk, Dijon mustard, garlic powder, onion powder, salt, and black pepper for about 1 minute until pale yellow and slightly frothy.
- Spread the diced ham evenly across the bottom of the prepared baking dish. Sprinkle about 1½ cups of the shredded Swiss cheese (and Gruyère, if using) over the ham. Reserve the remaining ½ cup for the top.
- Slowly and evenly pour the egg mixture over the ham and cheese. Gently shake the dish or use a spatula to ensure even distribution. Do not stir.
- Sprinkle the reserved ½ cup of Swiss cheese over the top.
- Bake on the middle rack for 35-40 minutes, until the edges are set and the center is slightly jiggly. If the top browns too quickly, tent loosely with foil around the 25-minute mark.
- Let the casserole rest for 10 minutes before slicing. This allows it to finish setting.
- Garnish with fresh chives or parsley, slice into squares, and serve warm.
Notes
For best texture, use room-temperature eggs and shred your own cheese. Avoid overbaking—pull when center is slightly jiggly. Let rest for 10 minutes before serving. Can be assembled the night before; add 5-10 minutes to baking time if starting from cold. For extra creaminess, use a water bath.
