  • 500 grams (1 package) frozen puff pastry, thawed
  • 1/2 lbs 273 grams, cooked bacon slices
  • 1/2 lbs 273 grams, cooked mushroom slices (white button or crimini)
  • 1/2 cup grated gruyere cheese (or preferred alternative such as cheddar, comte, jack, or mozzarella)
  • 4-8 large eggs
  • 1 large egg, beaten with 1 tsp of water in it.
  • 1/4 tsp dried thyme or 1/2 tsp fresh leaves to garnish


  1. Preheat oven to 400° F and line a baking sheet with non-stick paper.

  2. On a lightly floured surface rollout puff pastry until about 3 mm thick, approximately 11" x 13". Prick all over with a fork or a the pointy end of a knife, leaving a 1" border. Using a pastry brush, brush border with egg wash (beaten egg with water). Bake for 15-20 minutes, or until just starting to brown.

  3. Top pastry with bacon, mushrooms and cheese creating little areas for the eggs to sit in. Crack eggs on top.

  4. Season very lightly with salt and with a bit more pepper. Sprinkle thyme all over.

  5. Bake for 4-8 minutes, or until egg whites are set and yolks are still soft.
