Ingredients

Scale
  • 4 large butter croissants (preferably day-old)
  • 8 oz (225g) cooked turkey breast slices
  • 6 crispy bacon strips
  • 1 cup shredded Gruyère cheese (100g)
  • ½ cup shredded sharp white cheddar cheese (50g)
  • 3 tablespoons (42g) unsalted butter
  • 3 tablespoons (24g) all-purpose flour
  • 2 cups (480ml) whole milk, warmed
  • Salt to taste
  • Freshly ground white pepper to taste
  • Pinch of nutmeg
  • 1 teaspoon Dijon mustard
  • About ¼ ounce (7g) fresh black truffle shavings (or a few drops of high-quality truffle oil as substitute)

Instructions

  1. Preheat your oven to 375°F (190°C). Butter a 9×13-inch baking dish thoroughly to prevent sticking.
  2. Slice each croissant in half horizontally and place the bottom halves in a single layer in the baking dish. Layer turkey slices evenly over each croissant base, then top with crispy bacon strips.
  3. In a medium saucepan, melt the butter over medium heat. Whisk in the flour to create a roux and cook for about 2 minutes until light golden.
  4. Slowly pour in the warmed milk while whisking constantly to prevent lumps. Continue cooking and whisking until the sauce thickens, about 5-7 minutes.
  5. Remove from heat and stir in shredded Gruyère and cheddar until melted and smooth. Season with salt, white pepper, nutmeg, and Dijon mustard. Adjust seasoning to taste.
  6. Spoon the creamy Mornay sauce generously over the prepared croissants, covering all the turkey and bacon.
  7. Bake in the oven for 15-18 minutes until the sauce is bubbling and golden on top and croissants are warmed through. Check at 12 minutes to avoid burning.
  8. Remove from oven and let rest for 2 minutes. Shave thin slices of fresh black truffle over each croissant using a sharp knife or truffle slicer.
  9. Serve immediately, ideally with a crisp green salad or light side to balance the richness.

Notes

[‘Use day-old croissants to prevent sogginess and maintain crisp edges.’, ‘Whisk constantly when making the roux and adding milk to avoid lumps.’, ‘The Mornay sauce should be thick enough to coat the back of a spoon but still pourable.’, ‘Cook bacon until just crispy but not burnt for best texture.’, ‘If fresh black truffles are unavailable, use a few drops of high-quality truffle oil as a substitute.’, ‘Warm milk before adding to the roux to prevent lumps.’, ‘Check the baking sauce at 12 minutes to avoid burning; tent with foil if necessary.’, ‘Reheat leftovers gently in a 325°F oven to keep croissants flaky; avoid microwaving.’]
