What Makes This Special

This pie is a vibrant showcase of Swiss savory pie tradition with a summer twist: the crust is naturally tinted coral with beets, filled with a Gruyère and goat cheese custard, flecked with blueberries, and scored in a patriotic motif for Independence Day. The advanced scoring technique transforms the pie into edible art, while the chilling method ensures each slice is creamy, vibrant, and refreshing—perfect for a festive summer gathering.

Ingredients

Combining classic Swiss cheeses, summer blueberries, and a coral-hued beet crust, this recipe celebrates the season. The filling is rich but balanced by pops of fruit, and the crust’s color is both dramatic and all-natural.

For the Coral Beet Crust

  • 250g all-purpose flour (structure)
  • 100g finely ground blanched almonds (crisp texture, flavor)
  • 10g fine sea salt (seasoning)
  • 35g freeze-dried beet powder (color and subtle earthiness)
  • 200g cold unsalted butter, cubed (flakiness)
  • 1 large egg, cold (binding)
  • 50ml ice water (hydration)
  • 2 tbsp white wine vinegar (tenderness)

For the Chilled Blueberry-Gruyère Filling

  • 200g Gruyère cheese, grated (Swiss flavor, meltiness)
  • 120g goat cheese, crumbled (tang, creamy texture)
  • 3 large eggs (set the custard)
  • 180ml heavy cream (richness)
  • 1 tsp black pepper (spice)
  • 3g freshly grated nutmeg (aromatic)
  • 250g fresh blueberries (summer freshness)
  • 1 tbsp fresh thyme leaves (herbal note)
  • 1 tbsp elderflower syrup, optional (subtle floral lift)
  • 50g red bell pepper, diced small (color contrast)
  • 40g shallot, minced (sweetness)
  • 20g fresh baby spinach, chiffonade (green accent)
  • 20ml olive oil (sautéing)

For Finishing & Decoration

  • 1 egg yolk + 1 tsp water (egg wash for shine)
  • 25g cold unsalted butter, melted (brushing the crust)
  • Sea salt flakes (crunch, finish)

Instructions

Step 1: Prepare and Chill the Coral Beet Crust

  1. In a food processor, pulse together flour, almond meal, salt, and beet powder until evenly mixed and a uniform coral color is achieved.
  2. Add cold butter cubes and pulse 8-10 times: you want pea-sized lumps for flakiness.
  3. Whisk egg, ice water, and vinegar together. Pour in a steady stream, pulsing until dough just comes together—don’t overwork.
  4. Turn dough onto a lightly floured surface. Knead gently to form a cohesive, streak-free disk. Wrap tightly and chill for at least 1 hour (preferably 2) until very firm. This step is essential for structure and vivid color.

Step 2: Roll and Line the Tin

  1. On a lightly floured (or chilled marble) surface, roll out dough to 4mm thickness.
  2. Drape over the tin, gently pressing into corners and sides. Trim excess, leaving 1cm overhang. Fold overhang inward for a double-thick edge.
  3. Chill 30 minutes (minimum). This prevents shrinkage.

Step 3: Blind Bake for Crispness

  1. Heat oven to 190°C (fan 180°C).
  2. Prick base all over with fork. Line with parchment and fill with weights.
  3. Bake 18 minutes. Remove weights and parchment; bake another 8-10 minutes until set and lightly golden. Cool completely on a rack.

Step 4: Prepare the Blueberry-Gruyère Filling

  1. In a skillet, heat olive oil over medium. Sauté shallot and red pepper until soft, 2-3 min. Cool.
  2. In a large bowl, whisk eggs, cream, black pepper, nutmeg, and elderflower syrup until smooth. Stir in Gruyère, goat cheese, sautéed veg, spinach, thyme, and half the blueberries.
  3. Season to taste with salt.

Step 5: Fill, Score, and Decorate

  1. Pour filling into cooled crust. Distribute remaining blueberries on top for a jewel-like effect.
  2. For advanced scoring: Roll out reserved scraps (from trimmed crust) to 2-3mm. Chill until firm (10 min). Using a sharp paring knife or lame, cut out patriotic motifs—stars, stripes, or abstract firework patterns.
  3. Place designs on top of the filling, gently pressing. For the scoring, make shallow cuts or etchings in the dough shapes for dimension but do not penetrate the filling. (See pro tips below.)

Step 6: Bake and Chill

  1. Brush pastry designs with egg wash. Bake at 170°C (fan 160°C) for 30-35 minutes, or until just set in the center—slight wobble is perfect.
  2. Cool to room temperature, then chill at least 1.5 hours. The chilling phase is essential: it allows flavors to meld and the pie to slice cleanly.

Step 7: Finish and Serve

  1. Just before serving, brush crust and decorative elements with melted butter for a glossy sheen. Sprinkle with sea salt flakes and extra thyme leaves.
  2. Slice with a hot, sharp knife, wiping between cuts for clean edges.

Pro Tips

  • For Beet Powder: Use freeze-dried beet powder for vibrant coral color without excess moisture. If you can’t find it, pulse dried beet chips in a high-speed blender.
  • Scoring Technique: Chill dough shapes thoroughly before scoring. Use a razor-sharp paring knife or baker’s lame, holding at a shallow angle, and etch gently. Avoid pressing too deep—score for design, not to cut through.
  • Chilling is Key: The filling must be fully chilled to achieve a sliceable, creamy texture. Let stand at room temperature 10 minutes before serving for best flavor.

Troubleshooting

Crust shrank or cracked? Ensure dough is well-chilled at every stage, especially after lining the tin. Avoid stretching dough into the tin.

Filling is runny after chilling? The pie may have been underbaked—ensure the center is just set before removing from the oven. Next time, bake a few minutes longer.

Variations

  • Swiss Alpine Version: Substitute blueberries with sautéed wild mushrooms and add caramelized onion for a forest-inspired pie.
  • Smoked Salmon & Blueberry: Layer smoked salmon ribbons atop the chilled pie before serving for a luxe, red-white-blue finish.
  • Vegetarian Red-White-Blue: Add roasted red peppers and torn mozzarella to the filling, and decorate with cherry tomatoes for more patriotic color.

Storage

Wrap the chilled pie tightly and store in the refrigerator for up to 3 days. Serve slices cold or at cool room temperature. Avoid freezing, as the custard may separate. To maintain the crust’s crispness, store uncovered for the first 12 hours, then loosely tent.

Embrace the artistry of scoring and the freshness of summer—this pie will be the centerpiece of your Independence Day spread!
