Sourdough Discard Curried Lentil Crackers
Crispy, thin crackers made with active sourdough discard and ground red lentils, spiced with warm curry powder. These are a smart way to use up your sourdough discard while creating a flavorful, protein-rich snack with warming Indian spices. They're vegan, require no special equipment, and come together quickly before baking.

Steps
Before you start
- Have active, bubbly sourdough discard at room temperature (fed 4–6 hours before baking)
- Preheat your oven to 375°F (190°C) during Step 3
- Line two baking sheets with parchment paper before you start rolling
- Have a food processor ready; this speeds up grinding the lentils
Grind lentils and spices
- In a food processor, combine dried red lentils, curry powder, sea salt, and black pepper.
- Pulse for 1–2 minutes until the mixture resembles fine flour; some tiny lentil pieces are okay, but aim for no large chunks.
- Transfer to a mixing bowl.

Ready when: Fine flour consistency with no large pieces of lentil remaining
Tip: Don't over-process to a paste; you want a coarse flour texture for better cracker structure and texture
Mix dough
- Add active sourdough discard and olive oil to the lentil flour mixture.
- Stir with a wooden spoon until all flour is moistened and a stiff dough forms.
- If the dough seems very dry and crumbly, add water 1 tablespoon at a time and stir until it comes together into a firm, cohesive dough that's not sticky to the touch.

Ready when: Stiff dough forms; not sticky but holds together when pressed
Tip: Sourdough discard thickness varies; start with no water and add only if needed—wetter discard may require no water at all
Preheat and prepare sheetsOven 375°F / 190°C
- Preheat your oven to 375°F (190°C).
- Line two large baking sheets with parchment paper.
Roll thin crackers
- Divide the dough in half.
- Take one portion and place it between two sheets of parchment paper.
- Using a rolling pin, roll as thin as possible, aiming for about 1/8 inch (3 mm) thick—you want them very thin so they crisp up during baking.
- The dough should be nearly transparent and uniform in thickness.
- Repeat with the second portion.

Ready when: Dough is very thin (1/8 inch / 3 mm), nearly transparent, and uniform in thickness
Tip: Rolling between parchment is key—it prevents sticking and makes cutting easier. Work quickly so the dough doesn't dry out
Cut and transfer to sheets
- Carefully peel off the top layer of parchment from each rolled portion, leaving the dough on the bottom parchment.
- Using a pizza cutter or sharp knife, cut the dough into ¾-inch to 1-inch (2–2.5 cm) squares, diamonds, or triangles; uniform size ensures even cooking.
- Slide the bottom parchment with cut dough directly onto your prepared baking sheets.

Ready when: Dough is cut into uniform pieces, approximately 1 inch (2.5 cm) across
Tip: Don't separate the pieces on the parchment—leave them touching as you cut; they'll separate and crisp individually during baking
Bake until crispyOven 375°F / 190°C
- Place baking sheets in the preheated 375°F (190°C) oven.
- Bake for 15–18 minutes, rotating the sheets from top to bottom rack halfway through (around the 8-minute mark) to ensure even browning.
- The crackers are done when they're golden brown throughout and completely crispy when you break one—they should shatter, not bend.
- Edges will brown first; if the edges look very dark but the center is still pale, rotate again or tent lightly with foil.

Ready when: Golden brown and completely crispy when broken; crackers shatter rather than bend
Tip: Keep a close eye after 12 minutes—oven temperatures vary, and burnt crackers happen fast. Pull them out while still a light golden color; they'll continue to crisp as they cool
Cool completely
- Remove the baking sheets from the oven.
- Let the crackers rest on the hot pans for 10 minutes—they'll continue to firm up from residual heat.
- Then transfer them (still on parchment or to a wire cooling rack) to cool to room temperature, about 10–15 minutes more.
- They'll become even crispier as they cool.
- Once completely cool, break apart any pieces that stuck together during cutting.

Ready when: Completely cool and fully crispy to the touch
Tip: Don't eat them straight off the pan—waiting allows moisture to escape and makes them truly crispy, not just hot and chewy
Good to know
Tips
- Active sourdough discard is essential: it should be bubbly and smell pleasantly sour, typically 4–6 hours after feeding. Stale or unfed discard will make denser, less flavorful crackers.
- Rolling between parchment paper prevents sticking and makes cleanup effortless. If dough sticks to parchment, let it rest 1 minute—the surface dries out quickly and will release.
- Thin crackers (1/8 inch) crisp up beautifully and taste far better than thicker versions, which can turn out chewy. Don't skip the rolling-thin step—it's the secret to success.
- Oven temperatures vary widely. If crackers look pale at 14 minutes, give them 2 more minutes; if they're browning fast, start checking at 12 minutes. It's better to pull them out slightly underbaked and finish in a low oven than to burn them.
Make ahead
The dough can be made up to 2 days ahead and refrigerated in an airtight container before rolling and baking. Baked crackers keep fresh in an airtight container for up to 5 days; re-crisp in a 325°F oven for 2–3 minutes if they soften from humidity.
Storage & reheating
Room temperature: Keep in an airtight container or zip-top bag for up to 5 days; the low moisture content keeps them crispy. Freezer: Baked crackers freeze in an airtight container for up to 3 months; no thawing needed—eat straight from the freezer or re-crisp in a 325°F (160°C) oven for 3–5 minutes. No refrigeration needed.
Substitutions
- red lentils, dried → Red lentil flour (¾ cup / 85 g). Use store-bought red lentil flour directly instead of grinding whole lentils; this saves time and works just as well, though whole lentils provide slightly more texture and wholeness.
- curry powder → Garam masala (2 tsp / 5 g) or tandoori spice blend (2 tsp / 5 g). For a different but equally delicious spice profile. Garam masala is warmer and more subtle; tandoori adds smoky, deeper notes.
- sourdough discard, active and bubbly → Sourdough starter fed 4–6 hours prior (¾ cup / 180 ml), thinned with 2 tbsp water. If using fed starter instead of discard, dilute it slightly with water to match the consistency of discard. The flavor will be slightly more sourdough-forward.
- olive oil → Melted butter (1 tbsp / 15 g) or melted coconut oil (1 tbsp / 15 ml). Butter adds richness and browning power; coconut oil gives a subtle coconut note that pairs beautifully with curry flavors.
