Ingredients
  

For the Base

  • 4 tablespoons Salted Butter Enhances richness and flavor; substitute with olive oil for a lighter option.
  • 12 ounces Baguette Provides the perfect structure; if unavailable, any crusty bread like ciabatta works wonderfully.

For the Filling

  • 8 ounces Deli Ham Adds a savory protein punch; for a lighter option, try cooked turkey or veggie alternatives.
  • 8 ounces Gruyère Cheese Contributes to creaminess and depth; Swiss cheese works as a great substitute.

For the Egg Mixture

  • 6 large Large Eggs Essential for binding and texture; there are no substitutes for this key ingredient.
  • 1 cup Whole Milk Offers moisture and richness; opt for low-fat milk if you want a lighter dish.
  • 1/2 cup Half-and-Half Increases creaminess; use heavy cream for richness or milk for a lighter approach.
  • 2 tablespoons Chopped Fresh Chives Adds flavor and vibrant color; feel free to substitute with green onions or omit entirely.
  • 1 tablespoon Dijon Mustard Imparts tanginess; yellow mustard can be used as an alternative.
  • 1 teaspoon Chopped Fresh Thyme Infuses an aromatic flavor; dried thyme can be swapped (1 tsp).
  • 1 teaspoon Kosher Salt Elevates and enhances overall flavors; adjust per your taste preference.
  • 1/2 teaspoon Ground Black Pepper Provides a subtle spice; freshly ground is best for maximum flavor.

For the Thickening

  • 1/4 cup All-Purpose Flour Thickens the egg mixture; use gluten-free flour if needed.
  • 1 pinch Pinch of Nutmeg Adds warmth and complexity; feel free to omit if you prefer.

Instructions

  • Preheat the oven to 350°F (175°C). This step is crucial for achieving that perfect golden crust on top—so don’t skip it!
  • Grease a baking dish with salted butter to prevent sticking. Be generous; we want all the delicious layers to come out easily!
  • Layer half of the baguette slices in the dish, creating a solid base.
  • Distribute half of the ham and half of the gruyère cheese over the bread.
  • Repeat with the remaining bread, ham, and cheese.
  • Whisk the eggs, milk, half-and-half, chives, mustard, thyme, salt, pepper, flour, and nutmeg in a bowl until well combined.
  • Pour the egg mixture over the layered ingredients, ensuring everything is evenly coated.
  • Bake for about 50-60 minutes until the top is golden, and the center is set at 160°F.

Notes

Garnish with fresh herbs before serving for an extra touch of color and flavor. Store leftovers in an airtight container for up to 3 days.
