Steps

Before you start
  • Use active, bubbly sourdough discard at room temperature (fed 4–8 hours prior)
  • Preheat your oven to 475°F (245°C) about 15 minutes before baking
  • Have a 12-inch (30 cm) cast iron or heavy-bottomed skillet ready
  • Cut eggplant and prep all toppings before starting the dough
  1. Make the dough

    • In a large bowl, whisk together the sourdough discard, bread flour, lukewarm water, and olive oil until shaggy.
    • Let sit for 5 minutes to allow the flour to fully hydrate.
    • Sprinkle the salt over the mixture and mix with a wooden spoon or your hand until fully incorporated and smooth, about 2 minutes.
    • The dough should be slightly sticky but hold together.
    • Cover with a damp kitchen towel.

    Ready when: Dough is cohesive and smooth, all flour is incorporated

    Tip: Don't overwork the dough—sourdough discard already has elasticity. A 2-minute mix is plenty.

  2. Bulk ferment the dough

    • Let the dough rest, covered, at room temperature for 45 minutes.
    • After 20 minutes, perform one set of stretch-and-folds: wet your hand, grab one side of the dough, stretch it up and fold it over itself, then rotate the bowl 90° and repeat until you've folded all four sides.
    • The dough will rise slightly and develop tension.
    + Show details

    Ready when: Dough should have risen about 25–30%, feel airy, and hold a stretch without tearing

    Tip: If your kitchen is cold (below 68°F / 20°C), add 10–15 minutes to fermentation time. You want visible bubbles on the surface.

  3. Roast the eggplantOven 450°F / 230°C

    • While the dough ferments, preheat your oven to 450°F (232°C).
    • Toss the eggplant cubes with 3 tablespoons (45 ml) of olive oil, salt, and black pepper in a bowl.
    • Spread them on a baking sheet in a single layer.
    • Roast for 20 minutes, stirring halfway through, until the edges are deeply browned and the flesh is completely tender and collapsing slightly.
    + Show details

    Ready when: Eggplant is deep golden-brown with crispy edges and creamy interior

    Tip: Cut the eggplant into even-sized pieces so they cook uniformly. Don't stir too often—let each side get golden for better flavor.

  4. Make the mint oil

    • While the eggplant roasts, blanch the fresh mint leaves in a small pot of boiling water for 10 seconds, then immediately plunge them into ice water to stop cooking.
    • Pat dry thoroughly with a kitchen towel.
    • Place the mint, olive oil, lemon zest, lemon juice, and sea salt in a blender or food processor.
    • Blend until smooth and bright green, about 1 minute.
    • Pour through a fine-mesh sieve into a small bowl, pressing gently on the solids.
    • Discard the solids.
    • The mint oil should be vibrant and drinkable.
    + Show details

    Ready when: Mint oil is smooth, bright green, and flows easily

    Tip: Blanching the mint preserves its bright color and fresh flavor. Don't skip the ice bath or it will darken.

  5. Shape and proof the doughOven 475°F / 245°C

    • Increase oven temperature to 475°F (245°C).
    • Place a 12-inch (30 cm) cast iron or heavy-bottomed skillet in the oven to preheat for 5 minutes.
    • Carefully remove the hot skillet and lightly brush the bottom and sides with olive oil.
    • Gently stretch and shape the fermented dough into a rough 10-inch (25 cm) round or rectangle (it doesn't need to be perfect), then carefully place it in the hot skillet.
    • Let it rest for 5 minutes to relax and puff slightly.
    + Show details

    Ready when: Dough is about 0.5 inch (1.25 cm) thick and puffy around the edges

    Tip: Working with hot pans requires confidence—if you're nervous, let the skillet cool slightly before adding the dough. The result won't be quite as crispy but will still be excellent.

  6. Bake the baseOven 475°F / 245°C

    • Transfer the skillet to the 475°F (245°C) oven and bake for 8–10 minutes until the bottom and edges are light golden and the surface is set but still slightly soft.
    • The base should smell fragrant and slightly tangy.
    + Show details

    Ready when: Bottom is light golden, edges are set and starting to brown, surface is no longer wet

    Tip: Don't fully bake the base—you'll return it to the oven after topping. Underbaking now prevents a burnt bottom.

  7. Add garlic and eggplantOven 475°F / 245°C

    • Carefully remove the skillet from the oven.
    • Scatter the minced garlic evenly over the surface, then top with the roasted eggplant, spreading it in a single layer.
    • Drizzle any pan juices from the eggplant over the top.
    • Return to the oven for 3–4 minutes until the garlic is fragrant and just beginning to brown at the edges.
    + Show details

    Ready when: Garlic is fragrant with golden edges; eggplant is soft and slightly caramelized

    Tip: Raw garlic can burn quickly, so keep this step short. You want fragrance, not char.

  8. Finish and serve

    • Remove the skillet from the oven and immediately drizzle the mint oil generously over the top of the flatbread, starting from the center and working outward.
    • Sprinkle with fleur de sel and, if using, crumbled feta cheese.
    • Cut into 2–4 wedges and serve warm directly from the skillet, with any remaining mint oil on the side for dipping.
    + Show details

    Ready when: Mint oil is drizzled and glistening; feta is distributed evenly

    Tip: Add the mint oil right before serving so its bright flavor and color don't fade from the residual heat. Reserve a small spoonful to serve on the side.

Good to know

Tips
  • For maximum flavor, use eggplant that is firm and glossy with no soft spots; older eggplants can be bitter and watery.
  • If your sourdough discard is freshly fed, wait until it peaks (maximum rise) so the dough has maximum lift and openness. A sluggish discard will give a denser crumb.
  • The mint oil is the star—don't skimp on it. A generous drizzle brings all the flavors together and adds a stunning visual finish.
  • For a crispy-bottomed flatbread, preheat the skillet in the oven and work quickly so the dough crisps immediately. If your oven runs cool, add 1–2 minutes to baking times.
Make ahead

Prepare the sourdough discard up to 1 hour ahead. Roast the eggplant and make the mint oil up to 4 hours ahead (store mint oil in the fridge and bring to room temperature before serving). Shape and bake the flatbread within 1 hour of serving.

Storage & reheating

Store leftover flatbread wrapped loosely in foil at room temperature for up to 1 day. Reheat gently in a 325°F (163°C) oven for 5–7 minutes to restore crispness. Mint oil keeps in the fridge for up to 3 days; store in an airtight container. Freezing is not recommended as the texture degrades.

Substitutions
  • fresh mint leaves → Fresh basil or a mix of basil and parsley. Use the same quantity. Basil will be slightly less floral but still bright and Mediterranean.
  • globe eggplant → Zucchini or summer squash (400 g total), cut into ½-inch pieces. Roast for only 15 minutes as these soften faster than eggplant. Expect a milder flavor.
  • crumbled feta cheese → Ricotta salata, crumbled, or labneh (Lebanese strained yogurt). Either gives a tangy, creamy texture. Use 0.5 cup (100 g) of either.
  • bread flour → All-purpose flour. The bread will be slightly less chewy and have a softer crumb, but the result is still excellent.
